Power storage device for e.g. gas-filled support of rear flap of motor car, has piston rod detachably locked at different positions in longitudinal direction of base part that is blocked in one direction by relative movement of rod

摘要

The device (10) has a base part (12) and a piston rod (14) in which under expense and/or release of force is introduced partially into a base part in a bar longitudinal direction (z). A piston rod with an actuator is connected to a locking link (18) guided in the longitudinal direction for locking the base part. The piston rod is detachably locked at different positions in the longitudinal direction of the base part. The base part is blocked in one direction by a relative movement of the piston rod. An independent claim is also included for a rear flap arrangement comprising a lid arranged at a rear aperture of a car body.
