Device for locking and unlocking closed doors to the interior of a motor vehicle

A device for locking and unlocking closed doors to an interior of a motor vehicle, comprising a lock mountable to every door and actuatable by a key, said lock having a locking element swivelably supportable at a door and having retaining means cooperatable with the door and arranged near a door opening so as to be fixed with respect to a vehicle body, said locking element being swivelable with respect to a swivel axis and having two catching means which together enclose an angle with respect to said swivel axis;

• a latch element having counter-catch means and spring-loaded relative to a catch position, said catching means of said locking element cooperating with said counter-catch means of said latch element;
• a motor-activated actuating element which swivels said locking element into said locking position for locking the door and moves said latch element against a spring force for unlocking the door and in so doing disengages said catching means and said counter-catch means;
• a lock motor having a power take-off shaft, said actuating element being a crank which is a working connection with said power take-off shaft and having a stop at a distance from its axis of rotation and also a shoulder, said locking element having a counter-stop with which said stop cooperates, said latch element having a counter-shoulder with which said shoulder cooperates, said crank having a circumferentially plane, said stop projecting out of said circumferential plane to one side and said shoulder projecting out of said circumferential plane toward the other side.

• a slide movable in a longitudinal direction between a first operating position and a second operating position and having a cam;
• and a handle swivelling said latch element against a spring force both outside and inside the door so that said catch and counter-catch means of said locking element and said latch element is engaged, said second swivel arm of said latch element having a stop face projecting into an orbit of said cam in such a way that said slide passes from said first operating position to said second operating position and said cam swivels said latch element against a spring force when the door and said handle are located in one of two closing states.

• a lock motor;
• and a shaft driven by said lock motor, said actuating element having two partial elements located one after the other in direction of its swivel axis, one of said partial elements having a driver and being connected with said shaft so as to be fixed with respect to rotation relative to said shaft, the other of said partial elements being rotatable about a swivel axis against a pretensioning with respect to said one partial element along an angle and also having a drive, so that said driver of said other partial element is held by spring force against said driver of said one partial element.
