Motor vehicle door lock actuated both from inside and outside - has eccentric for circuit warning deiver doors cannot be opened from inside

摘要

The lock system has an internal opening and actuating handle which has an actuating linkage and the outside handle is coupled to his linkage. The arrangement has a cylinder lock and a safety key and the lock cylinder has an eccentric which acts on the door lock. This eccentric closes an electrical contact when the ignition circuit is connected. The eccentric connects in this case a signal generator such as a lamp or an acoustic signal. This reminds the driver that some door locks of the vehicle are locked in such a manner that they cannot be opened from inside. The eccentrics of the right hand and left hand doors respectively actuate electrical contacts which contact the signal generator when the ignition circuit is connected.
