Description
- This invention relates to a seat and more especially, this invention relates to a seat with an inflatable seat portion.
- There are many types of seats comprising a seat portion and a back rest portion. The seats are often such that the seat portion is not comfortable to sit on and does not give adequate support to the posterior of a person sitting on the seat portion. The seat portion may, for example, restrict the positioning of the person's pelvic girdle and it may apply undue pressure to the person's ischial tuberosities, in addition to restricting local blood flow and pinching local nerves in the region of the person's posterior.
- In International Publication No. WO 2005/002914 there is disclosed a seat comprising a seat portion and a backrest portion, the seat portion comprising a main portion and an insert portion, the insert portion being such that it fits into a complementarily shaped recess in the main portion. The insert portion comprises a pair of pads which are positioned so as to be underneath the cheeks of the posterior of a person sitting on the insert portion. The insert portion also comprises a pair of legs which are positioned so as to be underneath the thighs of the person sitting on the seat portion. The insert portion and the main portion are made of a foam material. The foam material of the insert portion may be of a different density to the foam material of the main portion.
- It is an aim of the present invention to retain the advantageous shape of the seat portion as set out in WO 2005/002914, whilst at the same time providing a completely different construction for the seat portion, and which seat construction gives varying control over the hardness/softness of the seat portion.
- Accordingly, in one non-limiting embodiment of the present invention there is provided a seat comprising a seat portion and a backrest portion, the seat portion comprising a seat main portion and a seat insert portion, the seat insert portion being such that it fits into a complementarily shaped recess in the seat main portion, the seat insert portion comprising a pair of pads which are positioned so as to be underneath the cheeks of the posterior of a person sitting on the seat portion, the seat insert portion comprising a pair of legs which are positioned so as to be underneath the thighs of the person sitting on the seat portion, and the seat insert portion being such that it is an inflatable seat insert portion which is able to be inflated and deflated by a user for maximum personal comfort of the user.

- Embodiments of the invention will now be described solely by way of example and with reference to the accompanying drawings in which:
-
FIG. 1 is an exploded view of a seat portion of a seat; and -
FIG. 2 is an exploded view of a backrest portion of a seat. - Referring to
FIG. 1 , there is shown a seat portion 2 of a seat. The entire seat is not shown but the seat comprises the seat portion 2 and a backrest portion. - The seat portion 2 comprises a seat
main portion 4 and a seat insert portion 6. The seat insert portion 6 is such that it fits into a complementarily shapedrecess 8 in the seatmain portion 4. The seat insert portion 6 comprises a pair ofpads legs 14, 16 which are positioned so as to be underneath the thighs of the person sitting on the seat portion 2. - The seat insert portion 6 is such that it is an inflatable seat insert portion 6. The seat insert portion 6 is such that it is able to be inflated and deflated by a user for maximum personal comfort of the user. The seat insert portion 6 is able to be inflated by gas in the form of air. The seat insert portion 6 is formed to have one single inflatable compartment. The
pads legs 14, 16 have curved faces which engage complementarily curved faces 18 in therecess 8. When inflated, the seat insert portion 6 will usually be softer than the seatmain portion 4. - The seat insert portion 6 includes control means 20 for inflating and deflating the seat insert portion 6. The control means 20 comprises a manually-operated
hand pump 22 which is connected to the body of the seat insert portion 6 by atube 24. Repeated squeezing of thehand pump 22 is effected to inflate the seat portion 6. If the seat insert portion 6 is inflated too much, then air can be released via an outlet valve (not shown). - The seat
main portion 4 is an inflatable seatmain portion 4. The seatmain portion 4 is also inflated by gas in the form of air. The seatmain portion 4 is formed to have one single inflatable compartment. The seatmain portion 4 is inflated by control means 26 which is basically the same as the control means 20 and which thus comprises ahand pump 28, atube 30 and an outlet valve (not shown). When inflated, the seatmain portion 4 will usually be inflated to be harder than the seat insert portion 6, but the reverse arrangement may be employed if desired. When the seatmain portion 4 and the seat insert portion 6 are inflated, then relative movement between the twoportions 4, 6 may occur if a person sitting on the seat portion 6 wishes to apply, for example, more weight on one side of the seat insert portion 6 than the other side of the seat insert portion 6. This relive movement may occur with all seat portions of the seat of the present invention. - Referring now to

backrest portion 32 comprises a backrestmain portion 34 and abackrest insert portion 36. Thebackrest insert portion 36 is an inflatable backrest insert portion which is able to be inflated and deflated by a user for maximum personal comfort of the user. Thus, for example, thebackrest insert portion 36 can be inflated to provide optimum lumbar support for the back of the user, irrespective of the height and weight of the user. - The backrest insert portion is inflatable by gas in the form of air. The backrest insert portion is formed to have one single inflatable compartment.
- The backrest insert portion includes control means 38 for inflating and deflating the
backrest insert portion 36. The control means 38 comprises a manually-operatedhand pump 40 which is connected to the remainder of thebackrest insert portion 36 by atube 32. Control means 36 also includes a control valve (not shown) for removing air from thebackrest insert portion 36 if it has been over inflated by operation of thehand pump 40. Thebackrest insert portion 36 has acurved face 44 which fits a complementarycurved face 46 of a recess 48 in the backrestmain portion 34. - The backrest
main portion 34 is an inflatable backrest main portion. The backrestmain portion 34 is inflatable by gas in the form of air. The backrestmain portion 34 is formed to have one single inflatable compartment. - The backrest
main portion 34 has control means 50 for enabling the backrestmain portion 34 to be inflated. The control means 50 comprises a manually-operatedhand pump 52 which is connected to the main body of the backrestmain portion 34 by atube 54. An outlet valve (not shown) is provided for removing air from the backrestmain portion 34 if this should be desired. - It is to be appreciated that the embodiments of the invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected. Thus, for example, the seat
main portion 4 may be made of a foam material instead of being inflatable. If thebackrest portion 32 is used with the seat portion 2, then theentire backrest portion 32 may be made of a foam material, or just the backrestmain portion 34 or just thebackrest insert portion 36 may be made of a foam material. Thebackrest portion 32 may be provided with a headrest portion (not shown). Gases other than air and also hydraulic fluids may be employed to inflate the chosen inflatable parts of the seat. A single pump and an appropriate control panel may be employed to inflate different parts of the seat. The pump may be an electrically-operated pump rather than a hand-operated manual pump if desired. - Although specific features of the invention are shown in some drawings and not in others, this is for convenience only as each feature may be combined with any or all of the other features in accordance with the invention.
