Abstract: A rotary latch (11) of a door lock is retained in a detent position by a spring-mounted retainer (20). A motor-driven working member (47) is provided for lifting said retainer (20). An energy-storing device (30) subjects a storing member (22) to a force and hereby serves to lift the retainer (20) out of its detent position in the rotary latch (11). To this end, the storing member (22) has a control surface against which the working member (47) travels in a first motor phase in order to load the energy-storing device (30). A counter-control surface (29) against which the working member (47) travels when lifting the retainer (20) in a staggered second motor phase is also provided. The aim of the invention is to provide a reliable door lock which will also function in the event of an accident. To this end, both the control surface (23) and the counter-control surface (29) are located on the storing member (22).

Abstract: A vehicle security arrangement includes at least one functional control unit, which provides a first code word; a theft protection control unit, which is coupled via a bus to the at least one functional control unit; and at least one input unit, which transmits to the theft protection control unit a second code word which the theft protection control unit forwards to the at least one function control unit. The theft protection control unit may initiate the provision of the first code word and the second code word. In the at least one functional control unit, a comparison of the first code word of the at least one functional control unit with the second code word takes place. In case of agreement between the first code word and the second code word, the at least one functional control unit enables itself.

Abstract: The invention relates to a closure comprising a closing head (20) and a lock (10) which rest on the immobile or mobile part of a door, flap or such like. The closing head (20) has an undercut axial shoulder (26) which during coupling is engaged by a radially mobile blocking member (11) in the lock (10). The lock (10) further comprises a sensing member (12) and a restoring member (13) for the blocking member (11). To make the lock less prone to malfunctions the invention provides for the axially spring-loaded sensing member (12) to be used as a locking means for the radially spring-loaded blocking member (11). When the locking effect is actuated the blocking member (11) is held in a release position in relation to the closing head (20). When the closing head (20) is engaged the sensing member (12) carries out an axial movement which releases the lock so that the radial spring-loading can move the blocking member (11) into its blocked position.

Abstract: The invention relates to a door lock provided with a roller catch (11). When the door is closed an immobile locking part (10) moves into said roller catch (11), causing it to pivot from an open position into a preliminary or main latching position, the roller catch (11) being held by a latch. For greater user comfort and a more compact door lock the invention provides for the same drive motor (30) to be used as locking aid and as opening aid. A transmission element (35) which can be moved into two different positions is introduced into the gear assembly (31, 37). The drive energy generated by the drive motor (30) is transmitted in one position to the roller catch and in the other position to a second output track leading to the locking latch (20).

Abstract: The invention relates to a lock that can be used with a flap, comprising a rotary unit that is made up of a rotary spagnolet that interacts with a closing element (10) and a rotating latch (22). In order to improve operational performance, the rotary unit is provided with a rigid catch (23) that preferably has two counter shoulders running in opposite directions. The output member (35) of a motor (40)—driven gear mechanism is also provided with two corresponding counter shoulders. This enables the motor to provide assistance with closing and, optionally, opening, whereby the rotary unit can be guided in a closing, tilting direction or an opening, tilting direction until the flap is fully closed or opened. The motor (40) comprises a gear mechanism with a group of gears that can be displaced between an engaged position and a separated position. The detent pawl (16) which interacts with the rotating latch (22) is disabled in the separated position, should an emergency arise.

Abstract: The invention relates to a rotating catch lock, wherein a closing member (10) interacts with a catch (20), which can be rotated between a closing position accommodating the closing member (10) and an open position which releases said member. The catch (20) is force-loaded (22) in an open position and is held by a spring-loaded (33) rotating latch (30) in the close position. Said latch (30) is moved by a motor (50) between the locking position retaining the catch (20) and a stand-by release position in which the spring-loaded latch (30) is propped up by the catch (20) as long as it remains in an open position. In order to use small compact motors (50), the invention provides that the stored energy (61) exerted by an energy storage mechanism (60) is transmitted to the latch (30) via a storage lever (40). Normally, the latch (30) is shifted into its stand-by position by the storage lever (40).

Abstract: A vehicle lock has a rotary latch and a closing member cooperating with the rotary latch that is rotatable between a closing position receiving the closing member and an open position releasing the closing member. A pivotable pawl is spring-loaded toward a locking position for securing the rotary latch in the closing position. The pawl has a release position for releasing the rotary latch. Interior, exterior, and safety handles can transfer the pawl into the release position. A common control lever switches the lock between first, second, and third states. The first state is the closing state; vehicle access is authorized via the interior and external handles. The second state is the locking state; access is denied via the exterior handle. The third state is the secured state; access is denied via the external and internal handles. A release lever connected to the control lever transfers the pawl into the release position when actuated by an access-authorized handle.

Abstract: The invention relates to a circuit for controlling an electrically activated motor vehicle door lock or the like, with a lock latch (1) and a detent pawl (2) which keeps the lock latch (1) in the closed position and with an electric motorized auxiliary closing drive (4) which is turned on after the lock latch (1) has reached a preclosing position and then moves the lock latch (1) by motor into the main closing position, there being a switch (16) which recognizes the preclosing position, especially a lock latch switch which scans the position of the lock latch (1).

Abstract: A motor vehicle gate lock having a lock catch (2) which can be shifted from an open position into a catch position and vice versa, a detent pawl (5) which holds the lock catch (2) in the catch position by catching, and a spring (7) which pretensions the lock catch (2) and detent pawl (5) relative to one another. The detent pawl (5) has an actuating surface (11) for the lock catch (2) at a distance from a catch projection (9) of the detent pawl. There is an electric motor drive (13) with a drive element (14) and a driving lug (16) that located off-center relative to the axis of rotation of the drive element. The driving lug (16) touches the actuating surface (11) by rotation of the drive element (14) in one direction and then lifts the catch projection (9) of the detent pawl (5) out of a catch projection (10) of the lock catch (2) which, in the open position, keeps the detent pawl (5) in a raised position.

Abstract: A process for triggering a electrically actuated motor vehicle door lock by a mechanical or electromechanical actuating handle. In this process, triggering takes place such that the electric motor drive always returns to an initial rest position after initial triggering and that actuation of the actuating handle for less than a minimum time does not trigger a switching function. Thus misactuations are unlikely. The operating characteristics of the motor vehicle door lock which is controlled using this process is matched as much as possible to the operating characteristics of mechanical or electromechanical motor vehicle door locks of conventional design. This facilitates acceptance among customers and prevents misoperations.

Abstract: In a fuel-injection valve, an armature (7) having upper and lower guide surfaces (12, 13) is arranged within a valve housing (1). Via the upper guide surface (12), the armature (7) is guided in a guide borehole (15) of the valve housing (1) directly below the magnet winding (3) of the fuel-injection valve. In this way the losses of magnetic flux are very small.
