Abstract
A spring element of an elastic material, in particular of synthetic plastic for taking a kinetic energy has a tubular piece, and a base plate which is fixedly connected to the tubular piece, the tubular piece having a wall thickness corresponding to a ratio between an outer diameter and an inner diameter of less than 2 and a structural height within the range of 0.7-1.3 of the outer diameter, so that during deflection with approximately 35% of an initial structural height an open end of the tubular piece is fitted over a force-loaded surface.
