Abstract: Disclosed is a microswitch that allows the setting of the microswitch to be detected. The microswitch includes a conducting element movable along a surface that includes at least one conducting track that is contacted by the movable conducting element. Actuating the microswitch moves the movable conducting element along the surface resulting in electrically connecting or disconnecting two electrical tracks and causing electrical switching. In addition, the contact surfaces electrically connected by the conducting element may have different electrically conductive regions such that moving the connected surfaces changes the electrical resistances. Different switch positions can be determined by measuring resistance.

Abstract: In order to minimize the sliding friction between the locking parts, that is, between the pawl and the rotary latch of a motor vehicle door lock, it is advantageous if, during the production process, the different latch surfaces of both locking parts are provided with a stamped contour have straight grooves and also with a stamped contour, characterized in that the provided grooves are oblique. The grooves which are oblique to the latch surface on the pawl can be produced such that the entire pawl or also the rotary latch are connected in an oblique manner to the base of the lock case housing which can be produced in several ways. Between the straight grooves and the oblique grooves, at least two coverings are provided which ensure that both locking parts are in mutual contact reducing the friction.

Abstract: In order to minimize the sliding friction between the locking parts that is, between the pawl and the rotary latch of a motor vehicle lock, it is advantageous if, during the production process, the different latch surfaces of both locking parts are provided with a stamping contour having straight grooves and with a stamping contour characterized in that the provided grooves are oblique. Said oblique grooves of the latch surface on the pawl are placed in the position indicated in figure such that the entire pawl is twisted about the longitudinal axis thereof. Also, at least two overlapping points are provided between the straight grooves and the oblique grooves such that both of the locking parts come into mutual contact reducing the friction.

Abstract: The invention relates to a lock for a door or flap, comprising a locking mechanism that consists of a rotary latch (1) and at least one pawl (2) for locking the rotary latch (1), the rotary latch (1) when in the detent position preferably initiating an opening moment in the pawl (2). The design of the rotary latch (1) is such that said latch is deformed under excessive stress in the locked state in such a way that an engagement between the pawl (2) and the rotary latch (1) is maintained or increases. A lock of this type will not open even under excessive stress.

Abstract: The invention relates to a method for producing motor vehicle door locks with the locking parts: a rotary latch and a pawl. Said latch and the pawl are stamped from rolled sheet metal defining vertical or approximately vertical edges with corresponding latch surfaces on the rotary latch and the pawl, and subsequently are provided with a covering while maintaining the catch surfaces. After stamping, the locking parts are bent in the region of the main latch and/or another latch resulting in the formation a contour which is void of stamped channels, and are then inserted into the lock housing box.

Abstract: A motor vehicle door lock comprising a locking mechanism (1, 2) and a mechanical lever gear (4, 5) as well as a motor-driven opening unit (7 to 9), which are respectively individually arranged for opening of a locking mechanism (1, 2), wherein in the normal mode, the motorized opening unit (7 to 9) provides a free movement of the lever gear (4, 5) in relation to the locking mechanism (1, 2) and the engagement of the lever gear with the locking mechanism (1, 2) in the opening mode.

Abstract: The present invention relates to a lock having a lock housing (3, 4) together with a lock cover (2), a lock case (9), a locking mechanism which is mounted on the base surface of the lock case (9), and an activation device for opening the locking mechanism. An activation lever of the activation device is at least partially covered by a pivotable flap (5) of a lock covering means (2, 3). The invention also relates to a method for manufacturing the flap together with a lock cover (2) by injection molding.

Abstract: The invention relates to an actuation device for a motor vehicle door lock (1), comprising a handle (7), and a locking lever (10) which renders the handle (7) inactive when accelerating forces of a predetermined magnitude occur, for example, in the event of an accident. In the normal operation, the locking lever (10) is displaced when impinged upon by the handle (7) and the handle (7) is simply rendered inactive in the locked operation.

Abstract: The problem addressed by the invention is providing a closing device for a motor vehicle that can be opened comfortably and nevertheless can be produced with little effort and cannot open in an unplanned manner. This problem is solved in that a closing device comprises a locking mechanism, which has a rotary latch and a pawl, and at least one electrical drive for opening the locking mechanism. The closing device has an actuating apparatus for actuating the electrical drive, such that the locking mechanism can be opened exclusively electrically. Thus, there is no mechanical system—for example, comprising a handle and a Bowden cable that connects the handle to a release lever of the locking mechanism—for enabling the locking mechanism to be opened exclusively in a mechanical manner, i.e., without the use of the electrical drive or another electrical apparatus. In the non-actuated state, the electrical drive is completely disconnected from the current-carrying electrical conductors.

Abstract: A motor vehicle door closure includes a locking mechanism having a rotary latch and a locking pawl for locking the rotary latch. The door closure also includes a blocking pawl for blocking the locking pawl when engaging, a release lever for releasing the locking pawl, and a locking lever that blocks the locking mechanism at least in the event of acceleration forces of a predetermined magnitude occurring, for example in an accident (impact). The release lever and the locking lever are arranged about an axis. This results in a particularly simple lock design.

Said switch identification light (15) comprises light-emitting diodes (16, 17) which illuminate the entire area around the child lock (6) such that even in unfavourable lighting conditions, the important component of the motor vehicle door (1) can be actuated safely and the switching position can be identified.

Abstract: The invention relates to a motor vehicle door lock equipped with a locking mechanism (1, 2, 15), an actuation lever unit (3, 4) acting on the locking mechanism (1, 2, 15), and a catch lever (10). The catch lever (10) renders the actuation lever unit (3, 4) ineffective, at least when acceleration forces of a given magnitude occur, e.g. in case of an accident (crash). According to the invention, the catch lever (10) blocks the actuation lever unit (3, 4) during non-deflected normal operation and in the event of a crash while releasing the actuation lever unit (3, 4) only for deflected normal operation.

In the normal operation, the locking lever (10) is displaced when impinged upon by the handle (7) and the handle (7) is simply rendered inactive in the locked operation.

Abstract: The invention relates to a motor vehicle door lock equipped with a locking mechanism (1, 2, 3), an actuation lever unit (6, 7) acting on the locking mechanism (1, 2, 3), and a catch lever (12). The catch lever (12) blocks the locking mechanism (1, 2, 3) at least when acceleration forces of a given magnitude occur, e.g. in case of an accident (crash), rendering the locking mechanism ineffective. According to the invention, the catch lever (12) acts upon a pawl (3) of the locking mechanism (1, 2, 3) in the direction of the blocking position of the pawl during normal operation and in the event of a crash while allowing the pawl (3) and thus the locking mechanism (1, 2, 3) to be in the releasing position only during normal opening operation.
