Abstract: The invention relates to a motor vehicle door lock equipped with a locking mechanism, an actuation lever mechanism acting on said locking mechanism, and a locking element. The locking element disables the actuation lever mechanism when accelerating forces of a defined magnitude occur, for example in the event of an accident. According to the invention the locking element is a transmission lever which can be impinged upon by a locking unit and is located between the actuation lever mechanism and the locking mechanism.

Abstract: The subject matter of the present invention is a motor vehicle control device that is provided with at least two closing/securing parts that can move relative to each other in pairs. The closing/securing parts each have functional surfaces on the edges which can be brought into contact mechanically. The closing/securing parts are produced from a planar base material and have, at their edges, machining marks created during the production process. According to the invention, one closing/securing part is provided with a bent section in such a way that the unprocessed bent section surface at least partially defines the functional surface of the relevant closing/securing part.

Abstract: The problem addressed by the invention is that of providing a microswitch that allows the setting of the microswitch to be detected. This problem is solved in that a microswitch is provided which comprises a conducting element that can be moved along a surface. At least one, preferably at least two, conducting tracks are integrated in the surface in such a way that the conducting tracks can be contacted by the movable conducting element. By means of the actuation of the microswitch, the movable conducting element is moved at least in some regions. During the movement, the movable conducting element lies on the surface along which the movable conducting element is moved. By means of the movement, two electrical conducting tracks are electrically connected to each other or an electrical connection between two conducting tracks is disconnected. Thus, the movement causes electrical switching.

Abstract: The problem addressed by the invention is that of being to switch a motor vehicle lock from normal operation to emergency or disruption operation within an especially short time and/or with the least possible expenditure of electrical energy. This problem is solved in that a lock for a motor vehicle having a lock mechanism and an electric drive is provided such that the lock can be electrically opened in normal operation. The lock has an additional operating state, called disrupted operation. In disrupted operation, the lock can be opened mechanically, which is not possible in normal operation. The lock comprises a mechanical energy accumulator for switching the lock from normal operation to disrupted operation.

Abstract: A motor vehicle door latch mechanism, comprising a circuit arrangement with at least one sensor (9, 10, 11, 12) and with at least one connected control unit (6, 7), wherein the sensor (9, 10, 11, 12) has two or more switch states, and wherein two different control units (6, 7) are connected to the sensor (9, 10, 11, 12).

Abstract: The object of the invention is to be able, with little expenditure of electrical energy and within a short time, to change over a lock, which can be opened electrically, such that said lock can also be opened mechanically. To achieve this, a locking device with a lock, in particular for a motor vehicle, is provided with a locking mechanism, the rotary latch of which can be latched to at least one pawl in a main latching position and in a preliminary latching position. The locking device has an electric drive with which the lock can be opened electrically in normal operation. It furthermore has an actuating device with which the lock can be changed over from normal operation to emergency operation in the event of an emergency. During this changeover, the lock is adjusted from the main latching position into the preliminary latching position, and the lock can be opened mechanically in said preliminary latching position.

Abstract: The invention relates to a motor vehicle door lock equipped with a locking mechanism, an actuation lever unit acting on the locking mechanism, and a catch lever. The catch lever blocks the locking mechanism 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 acts upon a rotary latch of the locking mechanism in the direction of the blocking position of the rotary latch during normal operation and in the event of a crash while allowing the rotary latch and thus the locking mechanism to be in the releasing position only during normal opening operation.

Abstract: The invention relates to a motor vehicle door closure comprising a locking mechanism having a rotary latch and a locking pawl for locking the rotary latch. Said door closure also comprises 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). According to the invention, the release lever and the locking lever are arranged about an axis. This results in a particularly simple lock design.

Abstract: The invention relates to a motor vehicle door comprising a door leaf with a drive, a magnetic device as a component of the drive, and at least one sensor which is associated with the door leaf. According to the invention, said magnetic device also comprises a magnetorheological element and/or a magnetohydrodynamic element which can be actuated by at least one magnet.

Abstract: The invention relates to a motor vehicle door lock equipped with a locking mechanism (1, 2, 3), an actuation lever unit that acts on the locking mechanism (1, 2, 3) and includes a release lever (4), and a catch lever (10). The catch lever (10) 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). According to the invention, the catch lever (10) blocks the locking mechanism (1, 2, 3) in the event of a crash while releasing the locking mechanism (1, 2, 3) only for normal opening operation.

Abstract: The invention relates to a motor vehicle door lock, which is equipped with a ratchet mechanism, a tripping lever for opening the ratchet mechanism and a ratchet lever that is pivotable about an axis. The ratchet lever renders the ratchet mechanism ineffective, at least with regard to the magnitude and direction of occurring retarding forces, for example in an accident (“in the event of a crash”) ineffective. According to the invention the ratchet lever is connected to an actuating lever applying force to a tripping lever in such an articulated manner that both levers together in the normal operation describe a predetermined normal actuation track (R1) without mechanical blocking and in the crash operation describe a crash actuation track (R2) deviating from the normal actuation track (R1) while simultaneously a mechanical blocking occurs.

Abstract: The invention relates to a motor vehicle door lock, with a locking mechanism consisting of a rotary latch and a pawl, wherein, in the closed state of the locking mechanism, the pawl bears with the locking contour thereof against a latching contour of the rotary latch, wherein the locking contour is formed in two parts with a retaining contour and a rolling contour.

Abstract: In order to minimize the sliding friction occurring between the locking parts, that is, between the pawl and the rotary latch of a motor vehicle lock, it is advantageous if, during the machining process, the different latch surfaces of both locking parts are provided with a punched contour and with a contour having a oblique machining groove. Machining grooves are formed, in particular on the latch surface thereof, after stamping the pawl. Defined shapes of oblique channels and/or machining grooves are produced, for example, by milling out the machining grooves. The oblique machining grooves are produced at a defined angle and guarantee that the straight channels on the rotary latch only have a few overlapping points with the oblique grooves, if both locking parts come into contact with each other.

Abstract: The invention relates to a device and a method for actuating a motor vehicle closing device and in particular a motor vehicle side door. The basic structure comprises a motor and optionally a connected transmission and/or a downstream coupling. Also, at least one sensor which is connected to a control unit is provided. According to the invention, the sensor, including the control unit are designed to detect a position (angle ?) of the motor vehicle closing device with respect to a motor vehicle body and also at least one additional functional state of the motor vehicle closing device.

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. Said 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 noises occurring between the individual locking parts of a motor vehicle lock, the grooves extending at a defined angle with respect to each other are produced on the locking parts or on the latch surfaces during the production process. The generated grooves then slightly overlap which considerably reduces the sliding friction and the disturbing noises.

Abstract: In order to minimize the sliding friction appearing between the pawl and the rotary latch of a motor vehicle door lock, it is advantageous, if during the production process, the various catch surfaces of both locking parts are associated with one or also two puzzle components, said puzzle components being inserted into the main latch area of the pawl or rotary latch, in a secured position in correspondingly adapted puzzle-shaped contours. Said edge surfaces can advantageously compensate the effect of the adverse stamped contours present on the other locking part such that both locking parts are in mutual contact reducing the friction.

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 whilst 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.
