Abstract
Hospital mattresses are generally made of foam plastic having predominantly open cell cores and are in the form of a parallel-epipedic block which is provided with a protective layer consisting of a plastic film which is easy to clean so that injurious substances and bacteria can be removed. Such mattresses have the drawback, however, that when used they produce sounds which are disturbing. These sounds are eliminated in accordance with the present invention by arranging a layer of fabric between the outer surface of the foam plastic block and the protective layer.
Claims5
A method for producing an integrated elastic body of increased noise suppression comprising a predominantly open cell foam plastic core having upper and lower surfaces, longitudinal surfaces and transverse surfaces, and an outer non-permeable plastic layer overlying and secured to said core, comprising the steps of:
- (A) positioning an inner, noise suppressing fabric layer overlying said upper and lower surfaces and said longitudinal surfaces of said core;
- (B) adhering said fabric layer to said core over at least a portion of the surface of said core;
- (C) positioning said outer layer overlying said adhered inner layer and adjacent said upper and lower surfaces and said longitudinal surfaces of said core;
- and
- (D) adhering said outer layer to said inner layer and said core over at least a portion of the surface of said core, thereby forming said integrated elastic body.
