    Abstract: A cushion structure constructed of a gel-like substance, such as an organosiloxane gel comprising the reaction product of an organosiloxane and a hydrogenosiloxane which is preferably a copolymer of a particular combination of siloxanes combined with an additive such as dimethylpolysiloxane. The gel is preferably covered, at least on one side, by sheet material which may be cloth, rubber, leather, foamed plastic or paper, depending upon the particular use. A flexible mesh-like member, such as dacron net, is preferably embedded within the cushion. The cushion structure is used to at least minimize pressure necrosis.

    Abstract: 1,170,286. Cushions. STRYKER CORP. 30 Nov., 1966 [22 Dec., 1965], No. 53598/66. Heading A4M. [Also in Division A5] A cushion includes a core 17 comprising a one-piece, coherent, elastic and semisolid organosiloxane gel having a hydrostatic property such that it is capable of flowing laterally upon application of external pressure and capable of automatically returning to its original shape when the pressure is removed whereby the pressure is equalized over the area of engagement of a body with the cushion. The core may have an elastomeric cover 18 and be located in an opening 12 or in a recess (22, Fig 5) in a foam rubber or plastics pad 11 (or 23). The cover (43, Fig 7 or 34, 35, Fig 6) may be applied only over the upper and lower faces of the core. The cushion may be supported on a seat frame or on a tractor seat (Fig 8). Alternatively, the cushion may have a rigid backing plate (50, 58, Figs. 9, 10). In another embodiment (Figs. 12, 13) the cushion comprises a heel pad with a harness (66).
