Abstract

A spring element, in particular a jounce bumper, for a vehicle shock absorber contains a longitudinal axis, a base body having a length along the longitudinal axis, and an end portion configured for contact against a damper cap of the vehicle shock absorber. The base body is elastically deformable between an uncompressed basic state and a compressed state in which the base body is at least partially compressed in the direction of the longitudinal axis. The end portion contains a contact surface that is wound along a helix around the longitudinal axis.
