ABSTRACT:
A pneumatic spring is equipped with a shell tube (12) which is telescopically guided on a pneumatic-spring cylinder (9) and which can snap into different positions. For bolting between the shell tube (12) and the pneumatic-spring cylinder (9), a bolt body (16) is attached to the cylinder bottom (17). In the bolt body (16), a bolt (18) is spring-loaded by a resilient force directed radially outward. In order to bolt the pneumatic-spring cylinder (9) relative to the shell tube (12), the bolt (18) engages in various breaches (19a and 19). Finger pressure required to release the bolting depends on which one of the two relative-shift directions between the pneumatic-spring cylinder (9) and the shell tube (12) is intended. (FIG. 1 )
