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.
Claims23
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.
A mattress system with a lower mattress and an upper mattress, where the upper mattress comprises, between an upper pad and a lower pad, a plurality of individual spring elements horizontally distributed over the mattress, each spring element including
- at least one circumferentially closed essentially cylindrical horizontal tube section made of elastic material,
- an essentially plane lower contact surface arranged on the lower end of the spring element and contacting the lower pad and
- an essentially plane upper contact surface arranged on the upper end of the spring element and contacting the upper pad, and wherein each spring element comprises a plurality of tube sections that are stacked one above the other and are firmly connected together.
