Abstract
Abstract An extendable and collapsible seat cushion manufactured from a unitary piece of foam. Channels are molded into the foam perpendicular to the length of the seat to allow for compression of the overall length of the seat cushion. Further, channels may be molded into the foam in a direction parallel to the length of the seat cushion to allow for compression of the seat cushion in the lateral direction as well. The channels have angular recesses near the surface of the cushion to provide a home for compression hinges created by connective foam and cloth disposed between segments of the cushion. A telescoping support frame is provided to assist in the compression and extending of the seat cushion. This support frame may be telescoped manually or with assistance by power.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
118 words
An extendable and collapsible cushion comprising: a unitary cushion member of flexible foam material having an upper surface and a lower surface; at least one channel of a depth less than the thickness of said unitary cushion member, said channel being disposed in the lower surface of said cushion member to divide said unitary member into a plurality of cushion segments; a compression hinge bridging said channel and connecting adjacent cushion segments; and said plurality of segments being movable relative to one another to open or close said hinge and to thereby adjustably extend or collapse said cushion member and said hinge being configured so that said hinge folds into said channel when said cushion member is collapsed.
Claim 2
Dependent Claim
118 words
An extendable and collapsible cushion comprising: a unitary cushion member of flexible foam material having an upper surface and a lower surface; at least one channel of a depth less than the thickness of said unitary cushion member, said channel being disposed in the lower surface of said cushion member to divide said unitary member into a plurality of cushion segments; a compression hinge bridging said channel and connecting adjacent cushion segments; and said plurality of segments being movable relative to one another to open or close said hinge and to thereby adjustably extend or collapse said cushion member and said hinge being configured so that said hinge folds into said channel when said cushion member is collapsed.
Claim 3
Dependent Claim
22 words
