Definitions
- the field of the invention relates to seating systems and, more specifically, to seating systems for children.
- Child seating systems have been used over the years. For example, child seats have been used in vehicles in order to restrain the movement of children in the vehicle and thereby prevent injury to the seated children in case of an accident involving the vehicle. For instance, rear-facing infant seating systems have been used to secure infants while forward-facing child seats have been used to secure older children. In all of these seating systems, the child is placed in the seat and secured to the seat using a harness system (e.g., a five-point harness) either incorporated into the seating system or using an existing harness of the vehicle. Various types of arrangements have also been used to attach the base of the car seat of the vehicle. In one example, the Lower Anchors and Tethers for Children (LATCH) system is used to attach the base of the child seat to the seat of the vehicle.
- LATCH Lower Anchors and Tethers for Children

Abstract
A seating system for a child includes a base. A formed seat is arranged so as to communicate with and selectively rotate about the base. A retention apparatus includes a first handle and the retention apparatus secures the formed seat to the base. A single actuation and substantially continuous movement of the first handle causes the formed seat to move around the base with respect to at least two different axes.
Description
- The field of the invention relates to seating systems and, more specifically, to seating systems for children.
- Various types of child seating systems have been used over the years. For example, child seats have been used in vehicles in order to restrain the movement of children in the vehicle and thereby prevent injury to the seated children in case of an accident involving the vehicle. For instance, rear-facing infant seating systems have been used to secure infants while forward-facing child seats have been used to secure older children. In all of these seating systems, the child is placed in the seat and secured to the seat using a harness system (e.g., a five-point harness) either incorporated into the seating system or using an existing harness of the vehicle. Various types of arrangements have also been used to attach the base of the car seat of the vehicle. In one example, the Lower Anchors and Tethers for Children (LATCH) system is used to attach the base of the child seat to the seat of the vehicle.
- One challenge faced by adults or others using these previous child seating systems has been being able to place the child in the child seat easily and quickly without dropping or otherwise injuring the child. More specifically, the child must be simultaneously held by the user and placed in the car seat without the user dropping or otherwise injuring the child. For forward-facing seats, this task can be difficult because the child may move as the user attempts to place the child into the child seat and/or the dimensions of the seat relative to the vehicle may be such that little extra space exists to easily maneuver the child into the seat.
- In an attempt to allow for easier child placement, some systems have been developed where the seat swivels towards the side of the vehicle (i.e., facing the passenger door). More specifically, in these approaches, the seat swivels from the forward-facing position to a side-facing position at the passenger door. When in the side-facing position, an adult can more easily place the child in the child seat.
- Unfortunately, while in certain respects these systems have made it easier for the child to be placed in a child seat, other problems still exist with these previous approaches. For example, complicated mechanisms were typically used to lock the seat to its base and these mechanisms were frequently difficult to unlock, turn, or operate, particularly when the user was simultaneously carrying the child in their arms. Users were also often required to unlock and move the seat in a series of complicated movements and actions increasing the difficulty in placing the child in the seat and/or the likelihood of injury to the child.
- Other problems limited the effectiveness of these previous systems in promoting child safety. For example, previous systems often included little if any additional protective measures to protect the child from injury in case of an accident (e.g., a side impact crash).
- These previous seats could also typically not be used interchangeably between different bases. To give one example, a child seat for use in a vehicle could only be used with the base in the vehicle and not with bases in any other system. Consequently, different seating systems were needed for different situations thereby increasing the cost and inconvenience to consumers.
- Approaches are described that allow a child seat to be easily and quickly rotated so that a child can be easily and quickly placed and secured in the seat. Specifically, the seat can be easily rotated by a single actuation and substantially continuous movement of a single handle or actuator, for example, from the forward-facing position to a side-facing position, thereby allowing the child to be placed in or removed from the seat.
- In many of these approaches, the child seat can be rotated in two or more different directions (i.e., about two or more axes) either simultaneously or sequentially. For example, the user may both rotate a seat towards the door and vertically adjust the seat in an upward direction with a single actuation and substantially continuous movement of a handle or other actuator. In so doing, the child may be quickly, conveniently, and easily placed and secured in the seat without utilizing complicated or difficult procedures.
- In many of these embodiments, a seating system for a child includes a base. A formed seat is arranged so as to communicate with and selectively rotate about the base. A retention apparatus includes a first handle or actuator and the retention apparatus secures the formed seat to the base. A single actuation and substantially continuous movement of the first handle causes the formed seat to move around the base with respect to at least two different axes.
- Various approaches may be used to enhance the protection of the child in the seat. For example, the formed seat may include an outer form and the outer form includes a substantially continuously-formed side portion and top enclosure portion that protect substantially the entirety of a child passenger. In another approach, the formed seat may include at least one protective member (such as at least one tubular member, at least one rod, at least one channel, or at least one plate) that is incorporated into the seat. Other approaches and/or components may also be used to provide protection for the child.
- Various mechanisms may also be used to secure the formed seat to the base. For example, the retention apparatus may include one or more couplers configured to be received in one or more receptacles or openings disposed in the base. The retention apparatus may further include one or more connection members that are coupled to the couplers. The connection members may include one or more cables, one or more cords, one or more wires, or one or more levers. Other types of connection members may also be used.
- In other examples, the seating system may include a second handle or actuator. The second handle also may be coupled to the retention apparatus. When actuated, the second handle completely disengages the formed seat from the base and allows the seat to be removed from the base.
- The seating system may also include or use one or more harnesses. One or more substantially vertical slots may be formed in the rear of the seat and be used to position the harnesses relative to the seat. The seating system may further include an indexing system (e.g., index markers) that is used to determine an appropriate position for the one or more harnesses to be positioned in the vertical slots.
- In some of these approaches, the seating system can be interchangeably used amongst various types of devices. For example, the base may be adapted to be attached to a vehicle seat, attached to an aircraft seat, incorporated into a stroller, or adapted to be incorporated into a piece of furniture. As such, the seat can be interchangeable and used with a variety of different systems. In other examples, the base may be integrated into a vehicular seat.
- The seating system can be locked at one or more positions. In one example, the formed seat is configured with the base so as to be lockable to the base in only a single forward-facing position. In this example, the base may include a groove (or pin guide) that includes a detent for temporarily retaining (without locking) the formed seat in a side-facing position. In other examples, the seat may be lockable in more than one position or in a different position other than the forward-facing position.
- The formed seat can have additional features that enhance the comfort of the child. For example, the formed seat may include ventilation openings that increase air circulation in the seat. In another example, the formed seat is constructed of a breathable material. Furthermore, various panels or cushions can be attached to the formed seat. For example, one or more panels or cushions may be attached to the formed seat to adjust the available passenger volume of the seat.
- The formed seat may be formed of one or more different components. In one example, the formed seat includes an inner shell and an outer shell. In this approach and when attached together, the inner shell and the outer shell form and enclose an open space or void that is situated between the inner shell and the outer shell. The open space may be left unfilled or filled with some type of cushioning material such as air sacks, air bags, or a supportive lattice structure.
- Thus, approaches are described that allow a child seat to be easily and quickly rotated so that a child can be quickly and easily placed and secured in the seat. The approaches described herein easy and convenient to use and, in some examples, provide enhanced protection for the occupant of the seat. In some examples, the seat can be interchangeably used between different systems (e.g., a child seat in a vehicle, a child seat in an aircraft, with a stroller, or as furniture).

Additionally, when used in a vehicle, the seat may be formed and configured to be used as an infant seat that is rear-facing. Other examples for placement and uses for the child seat are possible. - As shown in
FIGS. 1 a-d, thechild seating system 100 includes a formedseat 106 and abase 104. In this example, thebase 104 is secured to the top surface of a vehicle seat. However, as mentioned above, it will be appreciated that the base 104 can be incorporated into the vehicle seat as well. The base 104 may be constructed of any suitable material such as plastic and may be of a substantially circular shape with a break or opening in the middle. The base 104 may also be metallic to provide an interface between theseat 106 and the seat of the vehicle. Other examples of materials may also be used to form thebase 104. The base 104 may include a lip, ring, or other receiving member that communicates with theseat 106 and allows rotation of the seat along any number of axes. - As shown in
FIG. 1 d (a cross-sectional view of thechild seating system 100 taken along line 128), the formedseat 106 includes aninner shell 112 and anouter shell 110. In one example, the dimensions of theinner shell 112 andouter shell 110 ensure that a void orspace 126 is formed and exists between theinner shell 112 and theouter shell 110. Alternatively, the formedseat 106 may be constructed from a single element or more than two elements. The void 126 that is formed may be of a variety of dimensions and shapes, but, in this example, is larger at the rear of thechild seating system 100. The void 126 can be left unfilled with solid material (i.e., the void 126 may remain filled with air) or the void 126 may be filled with a cushioning material (e.g., air bags, air sacks, supportive lattice, or the like). Theinner shell 112 is coupled to theouter shell 110 with any suitable coupling mechanism such as by a sliding locking member formed or attached to theinner shell 112 that is received by a receptacle in theouter shell 110. Alternatively, other approaches can be used to couple theinner shell 112 to theouter shell 110 such as screws, bolts, levers, or any other type or combination of coupling elements. - The formed
seat 106 and its components (e.g., theinner shell 112 and the outer shell 110) may also be constructed from any suitable rigid material. For instance, theinner shell 112 andouter shell 110 may be formed from plastic or structural foam. The material may be of a honey-comb or lattice structure. Theinner shell 112 and theouter shell 110 may be formed by any suitable technique such as by using injection molding, milling, or any other appropriate approach. Other materials and techniques may also be used to form theinner shell 112 and theouter shell 110. Theouter shell 110 rests on surface (e.g., a circular surface) of thebase 104. Theshells 110 and/or 112 may also be perforated with ventilation openings to increase air circulation and provide additional comfort for the child passenger. - The
outer shell 110 has an outer form or shape. The outer form or shape includes a substantially continuously-formedside portion 132 andtop enclosure portion 130 that may protect the child occupying the formed seat. More specifically, theportions portions seat 106 may include one or more tubular members, rods, channels, or plates to protect the child in case of an accident of the vehicle. Other approaches and/or protective members or components may also be used to protect the child. - The formed
seat 106 is covered by panels orcushions cushions cushions cushions - A handle 102 (or other actuator) is actuated to unlock the
child seat 106 from thebase 104 and rotate theseat 106 between a forward-facing and side-facing position. Anopening 101 in the front of thebase 104 allows for placement of thehandle 102. Thehandle 102 may include a connector, which secures the handle to theseat 106. - The
handle 102 may be actuated (e.g., pulled, snapped up, or rotated) and, in a substantially continuous movement, the formedseat 106 rotated along a first axis and along a second axis. Although a handle is shown in the examples described herein, it will be appreciated that any type of actuator such as a rotatable knob, lever, or switch may also be used. Other examples of actuators are possible. - The rotation about the two axes may be simultaneous or sequential. For example, the
seat 106 may be simultaneously rotated about the base and vertically adjusted or first rotated and then vertically adjusted. Thehandle 102 may also be used to turn theseat 106 about thebase 104. Additionally, it will be appreciated that rotation about any number of axes can be accomplished using the techniques described herein. - A
connector 108 is used to connect thesystem 100 to a seat in the vehicle. For example, theconnector 108 may include a loop or some other mechanism to secure the seat belts of the vehicle to the base 104 thereby securing thesystem 100 to the vehicle. - In one example, tubular
protective members 114 provide a protective frame that shields the seat occupant from the impact of a crash. As described herein, other examples of protective members are possible. - Substantially
vertical slots 117 allow placement of a harness (not shown inFIGS. 1 a-1 d). In one example, the harness may be a five-point harness that is incorporated into theseat 106 and is retracted by a retractor. Alternatively, an existing harness or seat belt of the vehicle may be used. As described elsewhere in the specification, an indexing system may also be used to allow the harness position to be adjusted within the substantiallyvertical slots 117. For example, the indexing system may allow adjustments to be made to the placement of the harness to take into account the age, weight, height, or other characteristic of the child. - Referring now to
FIG. 2 , another example of achild seating system 200 is described. Theseating system 200 includes a formedseat 202 and abase 204. As with the example ofFIG. 1 , the formedseat 202 communicates with thebase 204 and rotates about thebase 204. In this regard, theseat 202 may rest or communicate with a lip or ring on thebase 204. This placement of the formedseat 202 in thebase 204 allows theseat 202 to rotate about any number of axes. Seating panels orcushions seat 202. - In one example of the operation of the system of
FIG. 2 , the formedseat 202 is rotated about thebase 204. As the formedseat 202 rotates about thebase 204, the formedseat 202 rotates along a first axis 212 (between a forward-facing position and a side-facing position) and a second axis 214 (vertically up and down). While, in this example, movement is about theaxes first axis 212,second axis 214, and athird axis 216. Additionally, the movement about theaxes axis 212 and vertically around theaxis 214. In another example, theseat 202 may be first turned around theaxis 212 and then vertically adjusted about theaxis 214. - The
seat 202 may be locked in the forward-facing position to thebase 204 and ahandle 205 is actuated to unlock theseat 202 from thebase 204. Then, in one substantially continuous movement, theseat 202 is moved approximately 90 degrees by thehandle 205 from the forward-facing position to the side-facing position. When theseat 202 is in the side-facing position, the child may be placed in theseat 202 and theseat 202 may be rotated back to the forward-facing position from the side-facing position. As theseat 202 is rotated, theaxes seat 202 and, in this example, theseat 202 rotates about theaxis 216 and theaxis 212. The rotation of theseat 202 about the twoaxes seat 202 or remove a child from theseat 202 without the need to resort to complicated or difficult adjustments and/or actuations of theseat 202. - Referring now to
FIG. 3 a, one example of the spacing between the inner shell and outer shell of a child seating system is described. As show inFIG. 3 a, the seating system includes aseat 302 and abase 304. A handle oractuator 306 actuates and allows rotation of theseat 302 about the base 304 as is described elsewhere in this specification.Latch connector 308 secures the base to a vehicle seat also as described elsewhere in this specification. Atop tether 310 secures the top of theseat 302 to the vehicle, and may be removed to allow for rotation. - As shown in the cross-sectional views of
FIGS. 3 b and 3 c, theseat 302 includes aninner shell 312 and anouter shell 314. Theinner shell 312 and theouter shell 314 are coupled together, for example, using pins, screws, bolts, locks, or some other coupling arrangement. In one example, theinner shell 312 andouter shell 314 do not fit snuggly or tightly against each other in all places. Instead, theinner shell 312 andouter shell 314 are formed and configured so that avoid 311 is formed and exists between theinner shell 312 andouter shell 314. In the example ofFIG. 3 b, small air packets 316 are used to fill at least some portions of thevoid 311. In the example ofFIG. 3 c,larger air chambers 314 are used to fill at least some portions of thevoid 311. In still another example, thevoid 311 is left empty and unfilled by any material (except by air). Filling at least some portions of the void with cushioning materials allows additional protection to be provided for the child. Additionally, the use of these additional materials may cushion the ride of the child in the seat, for example, as the vehicle (in which the seat is situated) moves. - Referring now to
FIG. 4 , another example of achild seating system 400 is described. Theseating system 400 includes anouter shell 402 and an inner shell 425. One ormore coupling members 413 on the inner shell 425 extend, snap, or are otherwise secured in to one or morecorresponding receptacles 423 in theouter shell 402 to couple the inner shell 425 to theouter shell 402. Alternatively, other types of coupling arrangements are possible. - The
outer shell 402 is formed around theprotective members protective members protective members - In this example, the
protective members - A handle or
actuator 401 is coupled to acable 403, which is in turn coupled to locking pins 406 (one shown inFIG. 4 ). It will be appreciated that thecable 403 can be constructed of wire or any other suitable material. Alternatively, thecable 403 may be replaced with some other connective arrangement such as levers or a combination of cables and levers. Other examples of connective arrangements may also be used. - When actuated, the
handle 401 pulls thelocking pin 406 fromopenings 408 in grooves (or pin guides) 405 that are disposed in a base 404 thereby allowing rotation of the seat about thebase 404. Although only two locking pins are shown, it will be appreciated that any number of locking pins can be used. In the locked position (e.g., in the forward-facing position) the locking pins 406 are retained in theopenings 408 that extend through thebase 404. In other words, since the locking pins 406 extend fully through thebase 404, the seat cannot be moved. In other examples, theopenings 408 are receptacles that do not extend fully through thebase 404. It will be appreciated that any number of locking positions (including zero) may be used. - The
cable 403 may be positioned in a channel inouter shell 402. In alternative arrangements, thecable 403 may be tunneled through theouter shell 402. - When the locking pins 406 are removed from the
openings 408 by thehandle 401, the seat (i.e., the inner shell and outer shell assembly) is allowed to rotate about thebase 404. In this example, the length of thegrooves 405 are predetermined to allow the base 404 to rotate approximately 90 degrees from the forward-facing position to the side-facing position. The length of thegrooves 405 can be adjusted to provide any degree of rotation. As the locking pins 406 move in thegrooves 405 as the seat is turned, the end of thegrooves 405 are eventually reached, rotation of the locking pins 406 within thegrooves 405 are halted, and the locking pins come to a temporary stop and rest in detents 407 (one of which is shown inFIG. 4 ). Thedetents 407 defines a slight dip in thegrooves 405 that provides a temporary resting place for the locking pins 406. In this way, when the seat is in the side-facing position, it is somewhat stable to allow for easier placement of the child but is still not fully locked. - Seat panels or
cushions 414 are placed on an outer surface of the inner shell 425. The panels orcushions 414 adjust the available volume of the seat to take into account the age, size, weight, height, or other physical characteristic of the child. Besides adjusting for the physical characteristics of the child, the panels orcushions 414 also cushion the impact of forces to the child as the vehicle moves or turns. As mentioned elsewhere in this specification, the seat panels and cushions are removable elements that, in one example, may be constructed of a variable density memory foam material that is washable. Additionally, the seating surface may be constructed from other materials such as breathable materials. - Substantially
vertical slots 420 extend through the inner shell 425 and allow harnesses to be used to secure the child. In this example, the harness may be incorporated into the seat system. Latch connectors 422 are used to secure the base 404 to a vehicle seat. For example, thebase 404 may include slots to encompass the safety belts of the vehicle. In other examples, fixed horizontal slots may be used. - Referring now to
FIG. 5 , an example of the locking pin arrangement is shown. It will be appreciated that any number of the locking pin arrangements described with respect toFIG. 5 can be used in the seating systems described herein. A lockingpin 502 is placed through anopening 504 in thebase 506. Thelocking pin 502 is forced into theopening 504 by the compressive force provided by aspring 515. In one example, thespring 515 may be a steel torsional spring, although any appropriate spring may be used. A first connection member 508 (e.g., a wire cable) extends to a first handle (not shown inFIG. 5 ) and aring 510 is bound to asecond connection member 509 to a second handle (e.g., a release grip, also not shown inFIG. 5 ). Thefirst connection member 508 is coupled to thelocking pin 502 by asuitable pin retainer 511. Thepin retainer 511 connects thelocking pin 502 to thefirst connection member 508 and provides a surface for the force of the spring 505 to act. - The
locking pin 502 extends into aholder 516 that may be formed with aseat shell 513. When the seat is not fully detached, theholder 516 holds thelocking pin 502 in place as the seat is rotated. Theseat shell 513 rests on thebase 506 and is allowed to rotate as thelocking pin 502 moves within a groove (or pin guide) 507. By resting on thebase 506, the seat is allowed to move about any number of axes. Thegroove 507 may utilize a low frictional material that is bonded to the base surface to act as a sliding contact for thelocking pin 502 to facilitate the smooth movement of thelocking pin 502 within thegroove 507. - When in a locked position, the
spring 515 forces the lockingpin 502 into theopening 504 and through thebase 506. The first handle or actuator is actuated to pull thefirst connection member 508, which in turn pulls thelocking pin 502 back (against the compressive force of the spring 505) and extracts thelocking pin 502 from theopening 504 thereby allowing movement of thelocking pin 502 within thegroove 507. Consequently, the seat is allowed to rotate about thebase 506. Upon return, the spring 505 pushes thelocking pin 502 into theopening 504 in thebase 506. - The second handle or actuator (e.g., a release grip) is used to pull the
locking pin 502 completely out of theopening 504 and also out of thegroove 507 in thebase 506. This action completely disengages thelocking pin 502 from thebase 506. After being fully detached, the lockingpin 502 may be reattached by releasing the actuator (e.g., release grip) from the locked open position. - Referring now to
FIG. 6 , another example of the child seating system is described.First opening 618 andsecond opening 614 extend through abase 601. A handle oractuator 602 is connected to afirst locking pin 604 and asecond locking pin 606. Although two locking pins are shown in the example ofFIG. 6 , it will be understood that any number of locking pins can be used. - The
first locking pin 604 is disposed within a firstlocking pin holder 608 and thesecond locking pin 606 is disposed within a secondlocking pin holder 610. In one approach, the lockingpin holders - When the seat is in a locked position, a
first spring 612 provides compressive force to force thefirst locking pin 604 through the firstlocking pin holder 608 and through afirst opening 618 in thebase 601. Asecond spring 616 pushes thesecond locking pin 606 into thesecond opening 614 in thebase 601. - The
handle 602 is actuated (e.g., pulled, moved, turned, or rotated) thereby pulling acable 619. The pulling of thecable 619 pulls the locking pins 604 and 606 thereby compressing thesprings openings handle 602. Consequently, the seat is free to rotate about the base. As the locking pins 604 and 606 move within their respective grooves (or pin guides) 620 and 622, the end of thegrooves grooves detents arrow 634. In one example, thedetents grooves springs openings - Referring now to
FIG. 7 a-d, examples of the child seating system ofFIG. 6 being rotated are described.FIG. 7 a illustrates the system before thehandle 602 is actuated. In other words, the seat is in a locked position with the locking pins 604 and 606 being retained in theopenings -
FIG. 7 b illustrates the system after thehandle 602 is actuated (e.g., pulled out). The locking pins 604 and 606 have been removed from theopenings grooves grooves 620 and 622). -
FIG. 7 c illustrates the system with thehandle 602 still actuated (e.g., pulled out) and being used to rotate the seat. The locking pins 604 and 606 (and seat) have now moved to a midpoint in thegrooves -
FIG. 7 d illustrates the system fully rotated (approximately 90 degrees) from the locked forward-facing position to the side-facing position. Here, the system has come to temporary rest and the locking pins 604 and 606 have been stopped by the end of thegrooves detents - Referring now to
FIGS. 8 a-8 d, the rotation of aseat 642 about the base 601 shown inFIGS. 6 and 7 a-d is further described.FIG. 8 a shows theseat 642 before thehandle 602 is actuated.FIG. 8 b illustrates the system after thehandle 602 has been actuated (e.g., pulled out). The locking pins 604 and 606 have been extracted from the openings in the base and are now free to move within the grooves (or pin guides) 620 and 622 in thebase 601 and theseat 642 is free to rotate about the base 601 (within the limits imposed by the retention apparatus). -
FIG. 8 c illustrates the system as theseat 642 is rotated and as thehandle 602 is still pulled down and used to rotate theseat 642. The locking pins 604 and 606 are free to move in thegrooves FIG. 8 d illustrates the system when theseat 642 is fully rotated from the locked forward-facing position to the side-facing position. Here, theseat 642 has come to temporary rest and the locking pins 604 and 606 are in the detents. It can be seen that as theseat 642 has been rotated about thebase 601, and theseat 642 has rotated aboutaxis 636 in the direction of arrow 634 (to turn the seat 642) and aboutaxis 638 in the direction of arrow 640 (vertically up and down). Rotation about theaxes - Referring now to
FIGS. 9 a-c, examples of an approach for completely disengaging the retention apparatus from the base are described. In this example, aseat 902 fits onto or rests on thebase 901. An actuator (e.g., release grip) 906 is accessible through an opening in the bottom of theseat 902 and is connected to the locking pins 908 and 910 viacables actuator 906 prevents unintended access of theactuator 906 by the child. - The
cable 914 is connected to ahandle 918. As shown inFIG. 9 b, the actuator (e.g., release grip) 906 is actuated by moving it in a direction indicated by anarrow 920. Actuating the actuator (e.g., release grip) 906 pulls the locking pins out of the openings inbase 901 and also out of grooves (or pin guides) 922 and 924. In so doing, theseat 902 is completely disengaged from and can be removed from thebase 901. - Referring now to
FIG. 10 a-f, an example of aseating system 1000 using a harness is described. Aseating system 1000 includes a formedseat 1002 and abase 1004. As shown inFIG. 10 a, theseating system 1000 also includesindex markers 1008. Theindex markers 1008 indicate positions where theharness 1006 can be positioned with substantiallyvertical slots 1010 based upon information related to the child. In this regard, theindex markers 1008 may be numbered and/or otherwise correlated with the child's age, weight, or height to give a few examples. Theindex markers 1008 may be painted on to the seat, decals may be used, or some other marking or indicting mechanism or approach may be used. - As shown in
FIGS. 10 b and 10 c, the seating system includes aharness 1006 and theharness 1006 fits through a harness guide 1009 (i.e., a harness fits across a harness guide in each of the substantially vertical slots). As shown inFIGS. 10 d and 10 e, theharness guide 1009 fits within the substantiallyvertical slots 1010 and is allowed to move up and down the substantiallyvertical slots 1010. In each of the substantiallyvertical slots 1010, theharness 1006 fits over theharness guide 1009 and, consequently supports and directs theharness 1006. Using theharness guide 1009, an adult or other person can adjust the position of theharness 1006 so that it fits comfortably and appropriately over the shoulders of a child and taking into account factors such as the weight, height, or age of the child. As shown inFIG. 10 c, abelt retractor 1001 is used to retract theharness 1006. - As shown in
FIG. 10 f, the back of aninner shell 1012 of the seat may includejagged retention edges 1014 so that theharness guide 1009 may catch and be secured into place by the retention edges 1014. Alternatively, other mechanisms may be used to hold theharness guide 1009 in place. - In many of the examples described herein, the seating system was described as being a forward-facing child car seat positioned on a seat in of any type of vehicle including cars, trains, boats, aircraft, trucks, or tractors (to name a few). Referring now to
FIGS. 11-14 , other examples of the usage of the child seating system are described. It will be appreciated that the approaches described herein are examples only and other examples are possible. Also, it will be understood that the bases as between different systems can be identical or substantially identical to allow the seat to be moved between and be interchangeably used with different systems. In one example, the seat can be moved between a base in the vehicle, a stroller, and a piece of furniture. - Referring now to

FIG. 12 , a seating system 1200 includes a formedseat 1202 that is an infant seat and abase 1204 that holds and provides for rotation of theinfant seat 1202. Thebase 1204 is coupled to avehicle seat 1206 with alatch connector 1208. For example, thelatch connector 1208 may include a loop or other arrangement and a user threads the safety belt of the vehicle through the loop thereby securing thebase 1204 to thevehicle seat 1206. In this example, the seating system has the same elements as those described above to allow for the rotation of the formedseat 1202 and these will not be further discussed here. - Referring now to
FIG. 13 , aseating system 1300 includes a formedseat 1302 and abase 1304 that is incorporated into astroller 1306. Thestroller 1306 may be any type of stroller for holding and transporting infants and/or older children. In one example, thebase 1304 is incorporated into (e.g., formed as part of and with) the stroller. - In another example, the
base 1304 is a separate piece that attaches to thestroller 1306 through any appropriate attachment mechanism such as screws, bolts nails, or clips. Other examples of attachment mechanisms are possible. In this example, the seating system has the same elements as those described above to allow for the rotation of the formedseat 1302 and these will not be further discussed here. - Referring now to
FIG. 14 , a seating system 1400 includes a formed seat 1402 and abase 1404 that is incorporated into furniture 1406.
