  • Patent number: 7543861
    Abstract: The lock includes an opening lever and a locking lever capable of displacing a connecting rod between a first position, in which the opening lever can cooperate with the connecting rod to cause the opening of the lock, and a second position which prevents the opening of the lock, blocking means for preventing a displacement of the rod between the first and second positions when the opening lever is put into an opening position before the locking lever is actuated, and an elastic device capable of memorizing both an unlocking action and a locking action when the locking lever is actuated while the connecting rod is being blocked by storing an unlocking energy or a locking energy in response to the actuation of the locking lever to automatically cause an unlocking or a locking of the lock when the opening lever returns into a position of rest.
