Rotary cylinder lock for motor vehicle, has guide housings receiving two types of springs which cooperate with two key grooves that extend to oppose drive force exerted by associated elastic return unit when key is inserted in rotor

摘要

The lock (1) has a rotor (10) mounted rotatingly inside a stator (20). Springs are mounted to move inside guide housings (41- 46) between a locking and an unlocked position, where each spring is coupled to an elastic return unit. Each one of the housings receives two types of springs which cooperate with two key grooves which extend to oppose a drive force exerted by the associated return unit when the key is inserted in the rotor. An independent claim is also included for a motor vehicle comprising a locking/unlocking device.
