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 aim of the invention is to design a door lock or flap lock which can be easily and reliably opened with little effort. Said aim is achieved by a door lock or flap lock comprising a locking mechanism that consists of a rotary latch and at least one pawl for locking the rotary latch, the design of the rotary latch and the pawl being such that the rotary latch can initiate a torque in the pawl, in particular an opening moment. The torque is dependent on the detent position of the pawl.
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 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 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 (a) 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:
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:
The invention relates to a locking device, in particular for a motor vehicle, having a catch mechanism and a coupling device for connecting to a motor drive. The coupling device comprises a coupling lever, which by virtue of a plurality of engagement lugs is able to pivot a coupling lever. The engagement lugs can be detected in succession by the coupling lever and are arranged in this respect one behind the other. The invention further relates to a plastics component for the locking device. An engagement lug is formed by an element protruding from a main face of the coupling lever in order to simplify production and to keep material costs and installation space to a minimum.
Abstract:
The invention relates to a motor vehicle door and to a method for acting on said motor vehicle door in terms of braking/holding or pulling closed/opening. The motor vehicle door is equipped with a driven (4, 5; 4) door leaf (1), a magnetic arrangement (4) as component of the drive (4, 5; 4) and at least one sensor (6) assigned to the door leaf (1). According to the invention, on the basis of a speed and/or position of the door leaf (1) with respect to a motor vehicle body (2) detected by means of the sensor (6), the magnetic arrangement (4) is supplied with power by a control unit (7) for either braking or holding, or pulling closed or opening the door leaf (1).
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.
