Abstract
A piston for a piston-cylinder arrangement, in particular a shock absorber piston exhibiting a piston body (6) provided with one peripheral web (12) protruding from the peripheral surface, disposed on said peripheral surface in both areas, each of which defining one end of the piston. Supporting connector elements (10), which extend longitudinally in the direction of the other end of the piston, are arranged successively at a distance from each other in a parallel manner contiguous to the peripheral web, whereby each two adjacent supporting connector elements (10) define a groove-shaped recess (11) and are provided with a collar-shaped seal (9) made of a thermoformable sealing material, which is formed on the piston body (6) in such a way that the peripheral webs (12) as well as the supporting connector elements (10) are incorporated into the material of the collar-shaped seal (9) over only a portion of their height.
