Abstract: A mattress having an anti-roll off feature is disclosed. The mattress has an innerspring unit having an array of coiled compression springs separating opposed parallel surfaces, wherein the surfaces are covered by a webbing made of a nonwoven polypropylene, and wherein the outer periphery of the webbing has horizontally disposed rigid foam planks wrapped and held in place by the webbing. The foam planks are formed from polyethylene foam. Additionally, vertically disposed rigid polyethylene foam planks with cross members are situated within the innerspring unit between the compressions springs at the periphery of the innerspring unit. The foam planks with cross members provide the support needed to achieve the anti-roll off feature. In an alternative embodiment, rigid polyethylene foam cylinders are placed within the rows of compression springs at the periphery of the innerspring unit to provide support at those locations.

Abstract: Multiple varieties of patient support surfaces are presented with a common modular assembly primarily including a perimeter chassis and integrated upper support element. Perimeter bolsters provide relatively firmer support for gently prompting a patient towards the center of the bed, without obstructing regular entry and egress. The added stability facilitates safer transfers and better sitting at the edge of the bed. Pressure redistribution air cylinders (turned either longitudinally or laterally) are captured by shaped, slotted inner bolsters aid underside arches of an integral foam topper. All such features work collectively to cradle and surround the air cylinders. The resulting interlocking, integrated design provides flexible progressive support while maximizing structural integrity. Different arrangements of air cylinders and static or dynamic performance thereof, either non-powered or powered, permit different embodiments to be created using the same modular assembly approach.

Abstract: An adjustable bed is provided having a lower frame (1) and an upper frame (3) mounted for longitudinal movement on the lower frame. A supporting surface (7, 8, 9, 10), including a back support member (7), is connected to the upper frame for pivotal movement about a transverse axis. The back support (7) is adjustable by an adjustment mechanism comprising two pairs of pivotally interconnected arms (17, 19), one of each pair being also pivoted to the lower frame (1) and the other arm of each pair being pivoted to the upper frame (3). The pivotal interconnections (18, 20) between the arms bear on the underside of the back support members, and a drive mechanism (13, 14, 15, 16) produces longitudinal movement of the upper frame with respect to the lower frame and, simultaneously, vertical movement of the pivotal interconnection (18).
