Abstract
This invention relates to a spring core of leaf springs for mattresses and seat cushions. According to the invention, the spring core comprises at least two plates opposite each other, having a multiplicity of spring elements broken out of holes. Preferably, the spring elements of the opposite plates are mirror-images.

SPRING CORE FOR MATTRESS OR SEAT CUSHION
BACKGROUND OF THE INVENTION
1. Field of the Invention This invention relates to a spring core for mattresses and seat cushions with leaf springs.
SPRING CORE FOR MATTRESS OR SEAT CUSHION
BACKGROUND OF THE INVENTION
1. Field of the Invention This invention relates to a spring core for mattresses and seat cushions with leaf springs.
2. Di~ inn of the Related Art Spring cores made with spiral springs for mattresses and seat cushions are known. Such spring cores, which are known in a variety of forms, are not corrosion resistant. These spring cores can only be made of spring steel and not of plastics, and therefore are expensive.
The use in mattresses and seat cushions of inserts made of synthetic foam, natural fibers, and other elastic filling materials in place of springs isalso known. These known inserts have the di~pd~ Ln~ of very poor air circulation and consequent trapping of moisture, as well as early fatigue and ~uu~ u~ -lL deformation of the insert material.
SUMMARY OF THE INVENTION
The objects of the present invention are to provide a spring core that can be made from plastics and also allow a sufficient circulation of air.
BRIEF DESCRIPTION OF THE DRAWINGS
Fig 1 is a schematic ~ t,.-L~Liul- of an Pmho~limPnt. of the spring core.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Fig. 1 shows a spring core in which two mirror-image plates la, lb are opposite each other, each having spring elements 3 broken and bent out of openings 2. The spring elements 3 are, by way of example, arranged byll~ LI;~lly and in line. It can further be seen that, as a result of the mirror-image Cu~ ru. ~iull and ~ l.. .IL of the spring elements 3, a multitude of leaf spring systems with movable supports 4 is formed, which do not transfer possible latera~ of the movable supports 4 to the surroundings.
The objects of the invention are achieved in that the spring core ~ 2143088 comprises at lesst two plates arranged opposite each other. Each plste is broken out to form a multitude of xpring elements. The spring e~ements of opposing plates are mirror-images of each other. This CUllbblU~.~iUII snd al .~ ;elllellL of the spring cores results in a multitude of leaf spring systems 6 with movable supports which do not trsnsfer a lengthwise 1 icrl ~Tn f~n t of the supporting points to the cushion material.
This 1U~ lU~.~iUu results in the special advsntages in that a large supporting surface is provided for the cushion material which may form a covering, snd that air csn circulste very well through the breaches. In sn especially advsntageous .,ho-lil . -,~ of the invention, the ends of the spring elements of a plate are shaped sa pans with edgeE formed 80 as to center the opposing plate. In a further especially adv~ h~eùu~ ~mho-liTni~nt of ehe invention, the plates are preferably made from a fiber-reinforced plastic, resulting in an up-to-date corrosion-resistant and lightweight spring corê.
