Description
- This application is a continuation-in-part of U.S. patent application Ser. No. 10/640,726 having a filing date of Aug. 13, 2003.
- The invention pertains to a lightweight, portable seat cushion that can be secured to a seat surface. The cushion is inflatable. The cushion may include a back support. The cushion can be folded into a small compact shape when not in use. The seat-attaching component also used to secure the compact folded pad in a convenient strap that allows the seat cushion to be carried through a belt, belt loop, or similar clothing component or accessory.
- Outdoor facilities typically provide benches or seats to facilitate use by spectators. Often the spectators pay for admission or otherwise provide a form of compensation to the host of the outdoor event. Enhancing the comfort of spectators can increase attendance and thereby may increase revenue received by the event host.
- However, most outdoor facilities have little or no form of seat cushioning. This is in part due to the harsh outdoor environment. The seats are often permanently installed outdoors. Any seat or bench cushions or padding device may also be subject to vandalism or destruction by natural elements. There is accordingly a need for a lightweight, compact inexpensive cushion that can be carried by an individual and that is adaptable for use with seats, benches, or bleachers. There is also a need for a cushion that can be temporarily fastened to the bleacher, bench seat or similar structure in order that it will stay in place when the occupant shifts position, stands or moves. It can be readily appreciated that an unsecured cushion may drop down from a bleacher-seating surface to the support structure below, and may be permanently lost to the user.
- Furthermore, it is beneficial to have a seat cushion that can also be utilized to increase seating comfort when used in any outdoor or indoor environments, including improving indoor seating and seating during outdoor activities that do not involve seats or benches, such as camping, beach activities and picnics.
- The apparatus pertains to a lightweight, portable seat cushion that can be secured to a fixed seat surface or utilized in the absence of fixed seating surfaces. The cushion can be inflatable. The cushion may include a back support. The cushion can be folded into a small compact shape when not in use, and the seat-attaching component also used to secure the compact folded pad in a convenient flexible and/or elastic strap that allows the seat cushion to be carried through a belt, belt loop, or similar clothing component or accessory. The cushion can be inflated by blowing or pumping air into a collapsible sealable cavity or it can be self-inflating. Self-inflating can include placing open cell foam in the sealable cavity. When a valve or similar port is open in the cavity, the ambient air pressure fills the empty cavity or the open cell foam.
- The apparatus provides a lightweight and compact seat cushion, which can be inflated prior to use and deflated for storage and transport. The apparatus provides a seat cushion that can be removeably attached to a seat, bench or bleacher structure. The cushion uses an attachment means to also contain or hold the cushion when packaged for transport or storage. The apparatus can include a cushion that also provides back support. The invention can include a light-weight, portable cushion device that can be stored and transported in a compact manner, and easily inflated to provide a comfortable seating surface at any location, including during hiking and camping.
- Other benefits of the invention will also become apparent to those skilled in the art and such advantages and benefits are included within the scope of this invention.

FIG. 20 illustrates an embodiment of the valve for the invention with an exploded view of one embodiment of the valve. - The above general description and the following detailed description are merely illustrative of the subject apparatus and additional modes, advantages and particulars of this apparatus will be readily suggested to those skilled in the art without departing from the spirit and scope of the apparatus.
- The apparatus comprises a lightweight, fluid inflatable seat cushion. The apparatus can be made from a lightweight strong woven material or from sheets of resinous material such as a plastic material used in fluid mattress or inflatable objects that can float in water or provide cushioning for camping, etc. The apparatus, can be composed of waterproof materials.
- The body of the apparatus may include a woven fabric type or other flexible material covering a fluid inflatable cushion component. The apparatus also may include one or more flexible and/or elastic straps attached to the flexible cushion component covering. The apparatus or components of the apparatus can be made of multiple layers. For example, the fluid inflatable cushion component may be made of a relatively lightweight plastic that forms a sealable inner pouch, surrounded by an outer layer of a high strength woven fabric material. It will be appreciated that the material or combination of materials be sufficiently flexible or pliable to allow folding and unfolding, without loss of strength and fluid sealing ability.
- In another embodiment, the fluid inflatable cushion component can include a pliable open cell foam material. The material can be compressed into a smaller volume when the fluid within the open (fluid permeable) cells is squeezed out of the cells. When the compressive force is removed, the ambient fluid pressure causes fluid to return to the individual pliable cells, having a relative low pressure due to the earlier removable of fluid, thereby causing the foam material to expand in volume. If the expanded foam is placed in a fluid-tight envelope or pouch which prevents fluid from escaping from the volume occupied by the foam, the composition of foam and hermetically sealable pouch creates a fluid cushion than can be later unsealed and compressed into a smaller space for transport and storage, and can be re-inflated by again opening the sealed pouch to allow fluid to return into the cells of foam. (After the release of the compressive force, the foam is in a low pressure, partial vacuum state.)
- In yet another embodiment, the foldable covering material having components permitting removable attachment(s) to stadium seating or other objects is provided separately from the collapsing fluid cushioning devices. In this embodiment, one or more separate objects such as inflatable/deflatable fluid cushioning devices can be inserted within the foldable pouches. In yet another embodiment, the foldable pouch is sufficiently impermeable to fluid such that a separate object, such as a lightweight, “down-like” sleeping bag parka, can be inserted into the hermetically sealable pouch to provide the fluid cushioning supporting. It will be readily appreciated that this embodiment of the apparatus creates a second use for existing objects having suitable characteristics or properties.
- The fluid inflatable cushion can have a fluid valve, which is of a type commonly used in the industry for fluid intake and deflation. Upon activation the valve can release the fluid in the inflated cushion and upon dormancy maintain the integrity of the inflated component, thereby not allowing fluid to escape. This embodiment allows for easy fluid removal and fluid inflation of the cushion, thereby improving the speed in which the user can use the apparatus. In one variation of the valve, the valve adds integrity support to the inflatable cushion components by preventing gas release from fluid cushion upon increased pressures.
- In yet another embodiment, a plurality of objects subject of this apparatus can be combined or removeably attached together to form a larger fluid cushioned area. For example, using existing attachment components of the object of this apparatus, multiple cushions can be linked together to form a cushioned pad over a hard ground surface.

In the illustrated embodiment, thecomponent 280 is permanently attached at oneend 283 to the flexible and/orelastic strap 250 by stitching or other means and attached at the other end byhook 282 andeye 281 means. It will be appreciated that other mechanisms may be used for fastening theapparatus 100 during transport such as a hook & loop connection device. Other commercially available attachment devices can also be used such as metal or resin plastic snaps. The components of theapparatus 100 described with reference toFIG. 1 are also shown inFIG. 1A . -
FIG. 2 illustrates theapparatus 100 unfolded. The portion of theapparatus 100 illustrated inFIG. 2 is thesurface 200A that will be proximate to the bench or bleacher surface (not shown). The user will sit on the opposite side of thecushion 200. Illustrated is the cushion securing flexible and/orelastic strap 250A containing at least one segment (eye or loop segment) 220 of the two-part hook & eye/loop material (Velcro™). The other part of the hook & eye material is attached to the opposing side (not shown) of the flexible and/orelastic strap 250. Also illustrated is aloop 310 having anannulus 315 through which the flexible and/orelastic strap 250 is looped as part of the method for securing theapparatus 100 to the bench surface. Reference is made toFIGS. 5 & 6 . - Also illustrated in
FIG. 2 is avalve device 410 for inflating and deflating thefluid cushion component 200. It is important to note that a portion of thefluid cushion component 200 may be comprised ofmaterial 200′ containing at least one segment (eye or loop segment) of the two-part hook & eye/loop material (Velcro™) such that counterpart material, such as elastic strap 250 aportion segment 220, containing at least one segment (eye or loop segment) of the two-part hook & eye/loop material (Velcro™) can adhere tomaterial 200′. Aflap 320 can cover the valve. This flap can also be secured by a hook & eye system, a male-female snap system such as that typically found on outdoor apparel and equipment, or other similar device. Theloop 310, which can be of metal, molded nylon or similar material, can be secured to the cushion in a variety of ways, including by the use of a fabric loop or sleeve (not shown). -
FIG. 2A is a further illustration of theapparatus 100, but containing a view of an innerinflatable bladder 200 that may be used to create the fluid cushion. The sealable bladder can be inflated by means of thefluid valve 410. The cushion will be inflated using a two-wayfluid valve 410. Thevalve 410 can be opened and fluid blown or forced into the pouch by the user. After being sufficiently inflated, thevalve 410 can be closed and theapparatus 100 used as a cushion over a hard surface. The bladder can be protected from puncture or tearing by one ormore covering materials 295 comprising the outer layer(s) of thecushion component 200. The other components illustrated inFIG. 2 are also shown inFIG. 2A . -
FIG. 2B illustrates the opposite side of thecushion component 200B and flexible and/orelastic strap 250B of the apparatus. The side of the flexible and/orelastic strap 250B depicted containsseveral eye segments 220, along with thehook 210 segment located proximate to thestrap end 205. This portion of theapparatus 100 is the underside of thestrap 250 referenced inFIG. 1 . Anattachment sleeve 231 for thestrap loop 310 is also shown. Thefluid valve 410 and cover flap are not shown. In the embodiment of theapparatus 100 depicted here, thecushion surface 200B will typically be the side of theapparatus 100 upon which the user will sit. It will be appreciated that in this arrangement, the fluid valve (not shown) may be located on the underside of the seat cushion. (ReferenceFIG. 2A .) - It will be appreciated that the placement of the eye segments, as well as pattern shape illustrated in
FIG. 2B may be modified to facilitate the desired securing arrangement.FIG. 2C illustrates such further embodiment utilizing a moreelongated eye segment 220 allowing thestrap end 205 to be secured to objects of varying diameters. Ideally, the flexible and/orelastic strap 250 can be used to hold thecushion 200 in place on the seat surface used for sitting, but it will be appreciated that it will also be advantageous to have thecushion 200 secured in a manner that will allow it to remain in reach of the user after standing or moving. In this manner, thecushion component 200 of the apparatus can be deemed to be loosely tied or leashed to an object such as a seat or bench support. The remaining components illustrated inFIG. 2C are also illustrated inFIG. 2B . The flexible and/orelastic strap 250B may be composed of material that is elastic, thereby allowing for a wide range of attachment applications. Some flexible and/orelastic strap 250B composition materials may include, but are not limited to, plastic or fabric woven materials. -

It is important to note that thevalve 410A can be utilized in any of the embodiments of the device or apparatus in question and is not limited in any other shape form other than that it allows for easy intake and outflow of fluid or gas from thefluid cushion component 200.Valve 410, can be but is not limited to avalve apparatus 410A (FIG. 20 ). -
FIG. 20 illustratesvalve apparatus 410A is preferably, but not limited to, composed of, a plurality of separate elements in mechanical communication with each other.Base 1003 is a valve base that is preferably, but not necessarily, composed of a plastic, rubber, or other non-reactive material. Thebase 1003 preferably contains an aperture disposed about its interior 1003A. The interior 1003A is substantially defined by an interior wall with a protrudingridge 1003B. The interior wall with a protrudingridge 1003B is preferably fitted to fixably engagespring coil 1002 in such a manner as to allow forspring coil 1002 to fit connectedly into interior 1003A without moving completely through thebase 1003. Adjacent and posterior to the interior wall with a protrudingridge 1003B is incline ridge 1003C. Incline ridge 1003C is preferably designed to releasably engagefluid plug 1004 in such a manner as to create a seal capable of preventing fluid flow. Thebase 1003 also has a contact surface 1003D, which comes into direct contact with and is adhered tofluid cushion component 200. Thefluid cushion component 200 and contact surface 1003D are fastened in such a manner as to create a fluid tight seal between base 1003D andfluid cushion component 200.Fluid plug 1004 is preferably designed in such a manner as to have an interior hollowed cavity 1004A, which is capable of securely engaging the nub portion 1001A oftop piece 1001 upon nub piece 1001A insertion. Thetop piece 1001 is preferably designed to be substantially equal in radius or greater in radius to thespring coil 1002, such that when thetop piece 1001 is actuated it can preferably evenly compress thecoiled spring 1002. Thetop piece 1001 is preferably porous so as to allow for increased fluid movement upon activation. - The
valve 410A is preferably assembled in the following manner, but it is important to note that one of ordinary skill in the art can appreciate that thevalve 410A may be constructed in a variety of manners.Spring coil 1002 is placed securely on protrudingridge 1003B located inbase 1003. Bothtop piece 1001 andfluid plug 1004 are preferably then interconnected by placingfluid plug 1004 with hollowed cavity 1004A facing coiledspring 1002 flush with incline ridge 1003C.Top piece 1001 is then placed, nub piece 1001A facing hollowed out cavity 1004 A, adjacent to coiledspring 1002. Nub Piece 1001A and hollowed out cavity 1004A are then pressed together preferably such that the nub piece 1001A is firmly inserted into the hollowed out cavity 1004A, thereby completing thevalve 410A. - In use, the
valve 410A, functions in the preferably following manners. The user can insert gas into thefluid cushion component 200 via thevalve 410A by either orally forcing fluid into thetop piece 1001 or by attaching thetop piece 1001 to an inflation device (not shown). Upon fluid being forced onto thetop piece 1001 thespring coil 1002 will compress and thefluid plug 1004 will move distal to thebase 1003 thereby breaking the fluid seal and allowing fluid into thefluid cushion component 200. The device can also work to deflate thefluid cushion component 200. If thetop piece 1001 is depressed after thefluid cushion component 200 is inflated then thespring coil 1002 will be depressed and thefluid plug 1004 seal with the incline ridge 1003C will be broken and the gas can escape thefluid cushion component 200. It should be appreciated that thefluid valve 410A adds increased integrity to thefluid cushion component 200 by allowing for the interior fluid cushion fluid pressure to maintain and support the fluid seal created byvalve 410A. - It will be appreciated that the
apparatus 100 may be used for multiple uses or for a single event of limited duration. It will also be appreciated that theapparatus 100 may incorporate team or organization identified colors or logos. Theapparatus 100, particularly the seat cushion, may identify advertisers, event sponsors or the specific event or venue. This may be particularly advantageous for embodiments of the apparatus intended for single or limited use. -

Thisseparate component 290 can provide back support by limiting the movement of theback support component 290 relative to theseat cushion component 200. In one embodiment, the movement is restricted by one or more flexible, but non-elastic cords orstraps 510 connecting theupper back support 290 with theseat cushion 200. All or a portion of the back support can comprise aninflatable cushion device 414 similar to the cushioning components for the seat previously discussed. InFIG. 7 , the inflatable seat cushion component is shown to be of threecomponents 450A - This
cushioning mechanism 414 can increase user comfort by providing greater rigidity to the back support. Rigidity can also be created by inclusion of one or more flexible, lightweight structures. This component can also be constructed in a manner that allows it to be folded with the deflated cushion package but reassembled into a single unit that is rigid in at least one direction. Examples of embodiments utilizing this component are illustrated inFIGS. 8 through 12 . Multiple components can be oriented together wherein the folding directionality of each is opposing the other. - In regard to the attachment of the
back support 290 to theseat cushion 200, thestrap 510 can be adjusted by latchingbuckles 520 or similar mechanisms commonly utilized in camping and travel equipment.FIG. 7 illustrates the adjustable nature of the buckle mechanism, resulting in a variable amount of strapping 511 pulled through thebuckle 520 to control the diameter or effective length of thestrap 510. Note that the separate strapping 250 used to package theapparatus 100 for storage and transportation and attachment to a seating surface is shown inFIG. 7 for reference. -
