An endless spring is an elastic body such as an oval or elongated or circular ring body for the transmission of loads in a main plane substantially centrally through the endless or ring body. Such a main plane extends in the plane of the drawing. The ring body is made up of a plurality of winding layers of fiber reinforced synthetic material. The windings in certain central body layers (2) preferably extend unidirectionally and the fibers in intermediate layers (3) and in outer layers extend at an angle relative to a main load application direction. The whole spring body includes a plurality of intermediate layers (3) and a plurality of outer layers (4) of synthetic resin impregnated fabric plies. The central body layers (2) form a winding body.

An endless spring comprising substantially straight leg portions connected by curved end portions, said endless spring forming a frame having a frame plane for taking up loads extending in said frame plane in a main load application direction, comprising a spring body having a plurality of layers (2, 3, 4) made of fiber compound materials and extending in parallel to said frame plane, said layers comprising a first layer type (2) in which fiber bundles are wound so that all the fibers extend unidirectionally in said first layer type and a second layer type (3, 4), each said second layer type comprising at least two plies (5, 6) in which the fibers extend in cross-over relationship relative to each other, said first layer type and said second layer type being arranged in alternate succession relative to each other.
