Abstract

Spring element is a hollow substantially cylindrical body which has a circumferential lip at one end, and consists of a material based on polyisocyanate polyaddition products. The detailed geometry of the element is defined by axial and diametral dimensions, as well as by angles and rounding radii. An independent claim is included for an automobile incorporating the spring elements.
