Abstract:
Body support apparatus comprising a support surface defined by support members,each support member being mounted for movement in a direction substantially normal to the support surface, wherein at least a multiplicity of the support members are each provided with a pusher, said multiplicity of support members being so arranged that movement of a first support member having a pusher in a direction substantially normal to the support surface and beyond a threshold distance relative to a second support member, the second support member being adjacent to said first support member, causes said pusher of said first support member to push said adjacent support member in substantially the same direction as said first support member, there being substantially no movement of said second support member caused by the movement of said first support member when the distance of relative movement is below the threshold distance, and a plurality of said multiplicity of support members are resiliently urged towards an unloaded position.
