  • Publication number: 20190145133
    Abstract: The disclosure relates to a motor vehicle lock, wherein the motor vehicle lock comprises an actuating lever which is pivotable about an actuating lever axis. The motor vehicle lock has an adjustable crash element which is adjustable into a released position in which the locking pawl is disengageable by an actuation of the actuating lever and into a crash position in which the crash element blocks the actuating lever in a blocked position or decouples the actuating lever from the locking pawl. It is proposed that the crash element is coupled to the actuating lever such that, with an actuation of the actuating lever and depending on the actuating lever speed, the crash element reaches the released position from a central position either in a first adjusting direction or the crash element reaches the crash position in a second adjusting direction and is latched in the crash position.

  • Publication number: 20180371803
    Abstract: A motor-vehicle lock has a latch mechanism, catch and an actuating lever, of which the actuation from a starting position into an actuating position makes it possible to disengage the catch, wherein the motor-vehicle lock has a crash element, which can be adjusted from a normal state into a crash state, in which the crash element blocks the actuating lever in a blocking position or uncouples it from the catch, wherein the crash element is coupled to the actuating lever such that, when the actuating lever is actuated at an actuating speed above a limit actuating speed, the crash element latches in the crash state. With the crash element latched in the crash state, a restoring action of the actuating lever into the starting position causes the latching action to be reversed and the crash element to be adjusted into the normal state.

  • Patent number: 10100558
    Abstract: The invention relates to a locking aid drive for a motor vehicle lock, with a drive housing, the locking aid drive being coupleable in terms of drive to the motor vehicle lock via a Bowden cable with Bowden cable core and Bowden cable sheath, and a driving motor with a downstream feed mechanism for producing driving movements and a coupling element for transferring the driving movements being provided. It is proposed that the coupling element can be brought, in particular by means of the drive motor, into at least one coupling position in which said coupling element is accessible from the outside for the production of a coupling of the Bowden cable to the coupling element, and otherwise is inaccessible from the outside for the production of a coupling of the Bowden cable to the coupling element.

  • Publication number: 20180187463
    Abstract: A motor vehicle lock in a fitted state interacts with a striker. The motor vehicle lock includes an adjustable catch and an adjustable locking pawl. The catch is adjustable into a main locking state and into an opening state, and the locking pawl is adjustable into an entry state, and into a lifted state. The motor vehicle lock includes a tensioning mechanism. When the catch is in the main locking state and the locking pawl is in the entry state, the tensioning mechanism can be brought into a tensioned state in which the tensioning mechanism introduces a mechanical preload into the catch in its opening direction. The tensioning mechanism can be brought into a relaxed state, in which the preload originating from the tensioning mechanism is reduced or cancelled.

  • Patent number: 9617763
    Abstract: A lock is provided especially for a door (2) or flap of a motor vehicle. Said lock has a lock housing (3) and a locking mechanism having a rotary latch (4) and a pawl, wherein the rotary latch (4) is arranged pivotably about an axis (22) and interacts with a locking bow (9), which is assigned to the bodywork (8), during the opening and closing of the door (2). At least one spring plate (15) which is oriented substantially parallel to the rotary latch (4) and surrounds the locking bow (9) in the locking position of the lock is arranged in the lock inlet region of the lock housing (3).

  • Patent number: 9540854
    Abstract: The invention relates to a motor vehicle door lock comprising at least one actuation lever (3) that is arranged in a lock housing (1, 2). Furthermore, a connection means (4, 5) is used for coupling the actuation lever (3) to an actuation element (6) arranged outside the lock housing (1, 2). Finally, an attachment element (2) is provided for mounting the connection means (4, 5) on the lock housing (1, 2). According to the invention, the attachment element (2) is designed as a partial housing (2) which can be combined with a main housing (1) to form the lock housing (1, 2) and which, in the mounted state, at least largely covers an opening (7) in the main housing (1) as well as a joining zone (8) between the actuation lever (3) and the connection means (4, 5).

  • Patent number: 9482037
    Abstract: The invention relates to a module for locking a motor vehicle lock. The aim of the invention is to design an easy-to-make and compact locking module for a lock. Said aim is achieved by a locking module comprising a housing, a switching nut that can be connected to a locking cylinder so as to rotate the switching nut by means of a key, and mechanism for converting a rotary movement of the switching nut into a linear movement to lock and unlock a lock. The mechanism comprises a dog which is linearly moved by a rotary movement of the switching nut. In the mounted state of the locking module, the linear movement of the dog actuates a mechanism that causes the lock to unlock or lock. In order to minimize the number of parts, the switching nut is rotatably mounted by the module housing.

  • Patent number: 9422754
    Abstract: A lock including a catch mechanism made up of a rotary latch and catch for latching the rotary latch. The rotary latch and catch have blocking surfaces for latching purposes. In the latched state, the blocking surface of the rotary latch rests on the blocking surface of the catch, and this prevents the rotary latch from being able to rotate in the direction of the open position. The lock also includes a component with an abutment surface, against which the blocking surface of the rotary latch butts in the open position of the catch mechanism. This abutment prevents the situation where, in the open position, dust can pass onto the blocking surface of the rotary latch. In addition, the abutment reduces the penetration of dust into the catch mechanism. An increase in the opening forces as service life increases is thus avoided.

  • Publication number: 20150097378
    Abstract: The invention relates to a lock for a door or hatch, having a locking mechanism that comprises a rotary latch and at least one locking pawl for latching the rotary latch. The rotary latch has a protruding blocking surface and a pocket-shaped recess or pocket adjoining the protruding blocking surface. The pocket-shaped recess extends arcuately from the protruding locking surface, whereby a ā€œVā€-shape is avoided. The arcuate shape prevents zones in which dust may accumulate to an increased extent. If dust is unable to accumulate to an increased extent, then there is correspondingly less dust available that may deposit between surfaces and cause creaking noises.
