Abstract
Abstract The invention relates to a generic mattress system which is easily adjustable to differing and space varying stresses with limiting spring paths. It has a top mattress and a bottom mattress with supporting elements connected to a frame and located in the plane of a frame. The elements are in U-shape and bear elastic support elements fastened to crosspieces. The upper mattress can also have spring elements between the upper and lower support, with each spring element having a section of elastic material.

Claim 1
Independent Claim
103 words
A mattress system having an upper mattress and a lower mattress, said lower mattress comprising a frame, upwardly open carrier elements of U-shaped cross section connected to said frame, each of them including an oblong cross-piece substantially coplanar with the frame between two essentially parallel upwardly-directed side-legs laterally attached to the crosspiece, a plurality of individual elastically compressible support elements distributed over the area bounded by the frame, each fastened to a cross-piece and extending upwardly between the side-legs, said support elements overtopping the side-legs in unloaded to normally loaded state and being essentially contained between the side-legs in a state of overload.
Claim 2
Dependent Claim
103 words
A mattress system having an upper mattress and a lower mattress, said lower mattress comprising a frame, upwardly open carrier elements of U-shaped cross section connected to said frame, each of them including an oblong cross-piece substantially coplanar with the frame between two essentially parallel upwardly-directed side-legs laterally attached to the crosspiece, a plurality of individual elastically compressible support elements distributed over the area bounded by the frame, each fastened to a cross-piece and extending upwardly between the side-legs, said support elements overtopping the side-legs in unloaded to normally loaded state and being essentially contained between the side-legs in a state of overload.
Claim 3
Dependent Claim
31 words
