COMPOSITE FOAM MATTRESS HAVING MULTIPLE LAMINATE CONSTRUCTION |
摘要 |
A compressible pad having a resilient core (40) wholly surrounded by and bonded to an upper layer (20) and a lower layer (30) of less resilient material wherein the upper and lower layers are bonded at their common perimeter to form an enclosed member. In one embodiment, a plurality of slits (28) are formed in one layer to permit passive ingress and egress of air into and from the void occupied by the core. In another embodiment, a valve is disposed between the environment and the core to permit air ingress and egress. Features of the invention include the formation of contours (12) on the upper and/or lower surface of the pad to alter the deflection properties of the pad, and/or facilitate storage of the pad or inflation of the pad. Preferably, the upper and lower layers are constructed from a closed cell foam and the core is constructed of an open cell foam. |
