Abstract
The mechanism comprises a part (116) sliding with respect to a base (102), locking means (144, 154) and control means adapted i) to store energy in elastic means (122) by contraction of the sliding part and ii) to release the energy by extending the sliding part by releasing of the locking means. The control means comprise an arm (130) articulated on the sliding part (116), a part (140) driven by a motor, with a cam surface (144) stressing a finger (134) integral with the arm, and a lock (150). In a first mode, the sliding part (116) is contracted via the arm (130) through the finger (134), then released after the reaching of a release area (C) of the cam surface, in the same rotation of the rotary part, whereas in a second mode, the sliding part (116) is contracted, then locked by the lock (150), then released after the reaching of a release are (D) formed by the cam surface, causing the unlocking by a reverse rotation of the rotary part.
