Abstract (en)
[origin: US5747140A] A completely vented upholstered body of grid plates with a wave profile includes solid portions of the grid which pass through the wave extrema of its wave contour. Many of the solid portions of the grid preferably are disposed transversely to at least one wave propagation direction and, in each case, continuously over a large portion of a wavelength, at a distance from one another. There is only a limited, specified bending deformation, during which the solid portions of the grid can be deformed largely independently of one another as if they were individual spiral springs. As a result, the upholstered body has a high point elasticity despite the plate construction. By adroit dimensioning of the course of the wave thickness, an advantageous diffusion of stresses can be achieved without stress peaks. Moreover, the work of deformation is absorbed uniformly in the upholstered material. This results in a long service life of the upholstered body. A single grid plate can be used or several identical or different grid plates, which are stacked one above the other and placed loosely on top of one another, can be fixed at the edges or fixed with positive locking or positive substance locking over solid portions of the grid, which are in supportive engagement with adjacent grid plates. Elastomers, such as natural rubber and thermoplastic elastomer, spring steel or plastics come in to consideration as material.
