A motor-vehicle latch mounted on a door has a front end pivoted about an upright axis, a rear end with a rearwardly directed end face, and an inside face immediately adjacent the rear end face, the door being movable relative to a frame member having a forwardly directed front face confronting the rear end face of the door in a fully closed position of the door. A holding element fixed to the front face of the frame member has a part projecting inward past the inside face of the door in the fully closed position of the door and having a support face facing forward toward the rear end face of the door. A retaining member, for example a bolt or wedge, is fixed in the holding element and a retaining element on the rear end face of the door is engageable with the retaining member to latch the door in the fully closed position. The part of the holding element projecting inward past the inside face of the door in the fully closed position thereof is formed with a forwardly directed bump lying inward of the inside face of the door in the fully closed position so that if the door is pushed back in a collision the inner face of the door will be prevented by the bump from sliding inward over the end of the holding element.

A lock with a servomotor, particularly a door lock for a motor vehicle, having a lock latch (fork member 1) which can be shifted between an open position and a detent position. In the detent position, the lock latch (fork member 1) reaches behind a pin 3 which, in the detent position, can be rotated by the servomotor about an eccentric axis from a prelocking position into a main locking position.

A latch for a motor-vehicle door comprises a housing, a door bolt engageable in and separable from the housing, a pivotal lock fork in the housing engageable around the bolt, and a release lever operatively coupled to the lock fork. Inside and outside latching elements respectively accessible and actuatable from inside and outside the door can each displace a common latching lever pivotal in the housing between a latched position and an unlatched position. Inside and outside locking elements respectively accessible and actuatable from inside and outside the door can similarly displace a common locking lever pivotal in the housing between a locked and an unlocked position. A coupling element connected to the locking lever is displaceable thereby between coupling and uncoupling positions respectively corresponding to the unlocked and locked positions of the locking lever. The coupling element is connected between the latching lever and the release lever only in the coupling position for displacement of the release lever into the freeing position only on displacement of the common latching lever into the unlatched position. A coupling is operatively engaged between the inside latching element and the inside locking element for shifting the latter into the unlocking position on actuation of the former. Thus actuation of the inside latching element with the latch locked unlocks the latch such that subsequent actuation of the inside latching element unlocks the door.

Motor-vehicle door latch

A motor-vehicle door latch for use on a vehicle door having inside and outside handles and inside and outside locking elements has a first housing part that contains a latch fork engageable in a locking position with a door bolt to retain same and lock the door, a lock pawl engageable in a retaining position with the fork to retain same in the locking position, an outside operating lever connected to the outside handle, an outside locking lever connected to the outside locking element, and an unlocking lever connected to the outside locking lever and operable to unlock the door. A second housing part contains an inside operating lever connected to the inside handle, an inside locking lever connected to the inside locking element, a coupling device pivoted coaxially with the inside locking lever and having one arm connected to the unlocking lever of the first housing part and another arm, and a central actuating unit. This unit includes an actuator, a spindle, a nut on the spindle displaceable between an unlock, a lock, and an antitheft position, and a slide displaceable jointly with the nut between the lock and unlock positions and connected to the other arm of the coupling device. An antitheft coupling is engageable between the nut, the coupling device, and the inside locking lever for coupling the inside locking lever to the coupling device and therethrough to the unlocking lever in the lock and unlock positions of the nut and for decoupling the inside locking lever from the coupling device in the antitheft position of the nut.
