Abstract

A helper spring is based on a polyisocyanate condensation product, preferably polyurethane, and is 78-82 mm high and of diameter 59-63 mm. The end is in the form of a lip and the element has a hollow internal diameter of 20-24 mm. Preferably the outside of the spring has grooves and protuberances with a distance between protuberances of 5-15 mm.
