Inflatable bedrest
First Claim
1. An inflatable bedrest, comprising:
- an inflatable bladder comprising a flexible air impermeable sheet material which when inflated defines three longitudinally extending side walls disposed in a triangular configuration when viewed in transverse cross section, and two opposite end walls which are transverse to said side walls, interior baffles comprising a pair of longitudinally extending panels which are disposed in a V-shaped arrangement when viewed in transverse cross section mounted within the bladder for supporting the bladder in said triangular configuration when the bladder is inflated, said baffle means comprising at least one panel joined between the interior of two adjacent side walls of the bladder, and an air delivery system comprising an opening communicating with the interior of the bladder.

Abstract
An inflatable bedrest which is composed of a bladder which when inflated defines three longitudinally extending side walls disposed in a triangular configuration. To support the bladder in the desired triangular configuration, there is provided an interior baffle mounted within the bladder which in one embodiment comprises a pair of longitudinally extending panels disposed in a V-shaped arrangement and joined to the side walls. In another embodiment, one or more transverse panels form the baffle, either alone or in conjunction with the V-shaped panels. The bedrest may be used to form an assembly which may be assembled to the head end portion of a bed mattress and serves to adjustably lift the head end portion.

11. An inflatable assembly for adjustably lifting one end portion of a bed mattress, comprising
an inflatable bladder comprising a flexible air impermeable sheet material which when inflated defines three longitudinally extending side walls disposed in a triangular configuration when viewed in transverse cross section, with said side walls including a base side wall and an upwardly inclined side wall, interior baffle means mounted within the bladder for supporting the bladder in said triangular configuration when the bladder is inflated, an air delivery system comprising an opening communicating with the interior of the bladder, a casing sized to closely receive the bladder when inflated, and a tubular cover configured to slip over and encase the one end portion of a bed mattress and being sized to overlie said upwardly inclined side wall of said bladder, with said cover being secured to the casing so as to prevent relative movement therebetween.
