A motor vehicle door lock with mechanical lock elements in a lock unit, the door lock includes a lock mechanism with several interacting elements in a control unit which is arranged at a location that is spatially separate from the lock unit in or on a motor vehicle door or hatch. The lock unit is connected to the control unit by a remote power transmission in the form of a Bowden cable, and the lock element in the lock unit can be mechanically actuated from an element of the lock mechanism in the control unit by the remote power transmission. In the lock unit, there is at least one component which is to be supplied with electricity to be triggered and/or to be interrogated, the at least one component is electrically connected by an electrical connecting element to lock electronics in the control unit, and the electrical connecting element is integrated into or combined with the mechanical power transmission.

Motor vehicle door lock with a lock unit and a control unit which are separate from one another

A motor vehicle door lock or the like including a housing with a lock latch and a detent pawl located therein, an electrical opening aid for electrical actuation of the detent pawl in a normal state, a lock mechanism for mechanical actuation of the detent pawl in a special state, remotely controllable control electronics for remote operation of the door lock, a chain of force exerting components that runs from an outside door handle into the lock mechanism, and a plurality of electrical sensors assigned to the chain of force exerting components in the lock mechanism, the plurality of electrical sensors being adapted to trigger the switching functions of the control electronics and the opening aid.

Motor vehicle door lock or the like

The invention relates to a circuit for controlling an electrically activated motor vehicle door lock or the like, with a lock latch (,) and a detent pawl (,) which keeps the lock latch (,) in the closed position and with an electric motorized auxiliary closing drive (,) which is turned on after the lock latch (,) has reached a preclosing position and then moves the lock latch (,) by motor into the main closing position, there being a switch (,) which recognizes the preclosing position, especially a lock latch switch which scans the position of the lock latch (,). The structure of the circuit is especially simple in that the negative pole (,) of the auxiliary closing drive (,) is always connected to ground or negative potential and the positive pole (,) is switched and is either at the positive potential of the vehicle voltage or at ground or is floated and that there is only one switch (,) and the switch (,) is between the ground and a switch terminal (,) and causes switching of the auxiliary closing drive (,). Here it is especially feasible if the auxiliary closing drive (,) shuts off automatically when the lock latch (,) reaches the closed position, especially when the overstroke position of the lock latch (,) which is somewhat on the other side of the closed position is reached, when therefore the positive pole (,) of the auxiliary closing drive (,) is then at ground or negative potential or is open. This applies especially when the criterion for shutting off the auxiliary closing drive (,), when the closed position is reached, especially when the overstroke position of the lock latch (,) which is somewhat on the other side of the closed position is reached, is the power consumption of the auxiliary closing drive (,).

Circuit for controlling an electrically operated motor vehicle door lock or similar

A door lock arrangement for motor vehicles with a closing cylinder arrangement (2) attached to outer sheet metal (1) of the body of a vehicle so as to be accessible from the outside and with a lock mechanism (5) attached in the body to be inaccessible from the outside. On the closing cylinder arrangement (2) there is transfer element (6) which establishes the connection of closing cylinder arrangement (2) to the lock mechanism (5). A corresponding coupling element (7) on the lock mechanism (5) engages the transfer element (6) by form-fit such that rotary motion of transfer element (6) is converted into a corresponding rotary motion of the coupling element (7). To secure against illicit penetration into the interior of the motor vehicle, it is provided that, upon forced removal of closing cylinder arrangement (2), the transfer element (6) is entrained by the closing cylinder arrangement (2) so that the coupling element (7), after forced removal of transfer element (6), is destroyed or otherwise modified such that it can no longer be actuated from the outside for purposes of opening the lock mechanism or such that the forced removal of the closing cylinder arrangement (2) triggers an anti-theft system (alarm system).
