Abstract: A motor vehicle lock comprising a lock housing, an electric power supply and at least one illuminant which can be connected to the electric power supply, emits light into a light-guiding element and can be placed directly on a circuit board located inside the lock housing.

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: 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: 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 closing/opening device (7 to 16) with at least one drive (7 to 11 and 13, 14), at least one transfer element (12, 15) and a driving pawl (16), in which the drive acts on the driving pawl with the assistance of the transfer element to open and close the locking mechanism, wherein a mechanical and/or electrical opening drive (7 to 11) and a mechanical and/or electrical closing drive (13, 14) each with a respective opening transfer lever (12) and closing transfer lever (15) are provided, in which the opening drive (7 to 11) including the opening transfer lever (12) in addition to the opening function for the locking mechanism (1, 2) is also designed to interrupt a closing function initiated by the closing drive (13, 14) in connection with the closing transfer lever (15).

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: A lock unit for a vehicle includes a rotatable catch biased in an opening direction about a catch rotation axis toward an open position of the lock unit in which a first recess of the catch is configured to receive a striker of the vehicle. Additionally, the catch includes a second recess disposed before the first recess in the opening direction. A pawl including a slot rotatable about a fixed pawl pivot axis is biased toward both the catch and the pawl pivot axis. The pawl includes a blocking arm which extends into the second recess of the catch when the lock unit is in a secondary latched position. A blocking lever of a ratchet abuts the blocking arm of the pawl against the catch in a primary latched position of the lock unit preventing rotation of the pawl away from the catch. When the lock unit is forced from the secondary latched position to the primary latched position, the pawl moves in a longitudinal direction of the slot avoiding the rotational blocking action of the ratchet.

Abstract: A method for error analysis and diagnosis uses error images stored in the system from which significant error information is extracted by analyzing the error bytes of the error image. The error information is combined, via tables, with error information extracted from other error bytes and a reference code is generated by the combination by means of which a predetermined error file is addressed, which contains information on the kind of error, its location and information on the remedying of the error.

Abstract: A priority control circuit for establishing connections between a data handling system element and a number of subsystems wherein request signals from subsystems are scanned and granted service in a sequence which is determined by their position in a priority ranking order. The scanner returns to the beginning of the order immediately after a request has been granted, the subsystem just serviced being bypassed in the next scan until all of the remaining request signals have been processed. Each time a request signal is encountered and service granted, the scanner returns to the beginning of the order, a new scan is begun and all prior requests serviced are bypassed. In the absence of any other requests or after all of the request signals have been serviced the bypassed subsystems are unlocked and a scan of all requests is begun.
