A latch for a motor vehicle, having a locking mechanism with a catch and at least one pawl, a triggering lever, whereby by means of the triggering lever a locked locking mechanism can be unlocked, an operating lever and a coupling lever, whereby the operating lever can be coupled with the triggering lever dependent on an operating speed of the operating lever by means of the coupling lever and whereby the coupling lever is mounted and guided in the operating lever.

Latch for a motor vehicle

An activation device for at least two spatially separated motor vehicle closure units, for example for a tailgate latch on the one hand and a fuel filler door latch on the other hand. The activation device possesses a linear drive with a linear actuator. Dependent on its activation direction, the linear drive impinges either the first motor vehicle closure unit or the other second motor vehicle closure unit. According to the invention, dependent on its actuating direction, the linear actuator impinges at least a pivotable activation lever to interact with either the first motor vehicle closure unit or the other second motor vehicle closure unit.

A motor vehicle door lock includes a locking mechanism having a rotary latch, a pawl, and an actuating lever mechanism having at least one coupling lever rotatable about an axis and a mass inertia element rotatable about an additional axis spaced apart from the axis of the coupling lever to guide the coupling lever, at least in the event of an accident. The coupling lever in its 'engaged' position connects the actuating lever mechanism mechanically with the locking mechanism and in its 'disengaged' position ensures that the actuating lever mechanism is locked and/or separated from the locking mechanism. The mass inertia element has a guide contour for the coupling lever that interacts with a contact contour of the coupling lever so that the guide contour and/or contact contour is configured so that a force exerted upon it runs essentially tangentially to the diameter of the associated axis.

Motor vehicle lock, in particular a motor vehicle door lock

A vehicle lock for a door or a flap of a motor vehicle, the vehicle lock including a locking mechanism with a catch and a pawl for latching the catch as well as a gear mechanism with a spindle for moving a nut and for transferring a motion and/or force to the locking mechanism by the nut movement for locking or unlocking the vehicle lock, and a clip for holding the spindle in an axial position. A simple and easy to produce vehicle lock with reduced number of parts, in particular without thrust plates, can be obtained.

A closing device for use in motor vehicles, in particular a backrest latch for locking and unlocking backrests in motor vehicles. The closing device is also provided with a multi-pawl locking mechanism substantially consisting of a catch, a comfort pawl that interacts with the catch and a blocking pawl that secures the comfort pawl. The catch includes an L-shaped insertion slot for a closing pin for forming at least a first closed position and a second closed position.

Closing device for use in motor vehicles

A motor vehicle door latch which is equipped with a locking bolt and a locking mechanism interacting with the locking bolt, including a catch and a pawl. The motor vehicle door latch possesses a stop lever pivotably located on the control lever, which interacts with a protrusion on the catch beyond a main ratchet position and a pre-ratchet position, whereby the protrusion corresponds to a third ratchet position with an increased distance of the locking bolt in respect of the main ratchet and pre-ratchet position compared to a catch axis. The stop lever impinges a triggering lever lifting the pawl from the catch in order to open the locking mechanism.

A latching device for motor vehicle applications, in particular to a multi-position backrest latch for locking and unlocking seat backrests in motor vehicles. The basic structure of the device has a locking mechanism substantially consisting of a catch and pawls, and also has a locking pin that interacts with the locking mechanism, and a cam element, which acts upon the locking pin in the direction of an open position. According to the invention, the cam element acts on a blocking element which engages over the locking pin.

The object of the invention is a motor vehicle door lock that is equipped with a lock housing (), also with a lock cylinder nut () supported in the lock housing (), and at least one locking element () that can be acted upon by the lock cylinder nut () via a positioning element (). According to the invention, the lock cylinder nut () has a connected eccentric element (). Said eccentric element () engages in an eccentric mounting () of positioning element () in order to displace it.

Motor vehicle door lock

A motor vehicle door latch is equipped with a locking mechanism including a catch and a pawl, a release element for the locking mechanism, and a memory element that effects an unimpeded opening movement of the catch from a closed to an open position and maintains the release element in an ineffective position in respect of the locking mechanism during the opening movement of the catch. The memory element includes at least two components with a control lever and a blocking lever interacting with the release element located thereon.

A latching system for a motor vehicle is formed of compact construction, that can manage with a small number of components and, enable bolting and/or opening the motor vehicle conveniently and quickly. The motor vehicle latching system is provided with an actuator and a drive for driving the actuator with a first acceleration and a second acceleration, whereby the actuator adjusts the latching system dependent on acceleration. If the drive accelerates the actuator sufficiently slow, the actuator moves the latching system into a first position. If the drive accelerates the actuator sufficiently quick, the actuator moves the latching system into a second position different from the first position. It is therefore adjusted by the drive dependent on the acceleration. Adjustment takes place quickly and especially conveniently without requiring an excessively large number of components. In particular, bolting and/or opening occurs in a motorized manner.

Latching system for a motor vehicle with actuator

A motor vehicle latch includes a retaining device which retains the pawl in its starting position with particular reliability during an opening process. The motor vehicle latch includes a locking mechanism encompassing a catch and a pawl for ratcheting of the catch. A retaining device is present which retains the pawl in its non-ratcheting starting position during opening. The retaining device encompasses a spring with an elastically rotated leg and a spring lever mounted thereon which can retain the pawl in its starting position during opening due to the elastic torsion. The pawl is retained in its starting position during opening with the aid of the spring lever and consequently with the aid of a torsional moment.

Latch for motor vehicle with pawl position retaining

A lock with a locking mechanism includes a rotary catch and a pawl for engaging the rotary catch, and a releasing lever for opening or releasing the locking mechanism. The lock may include a blocking lever capable of blocking the pawl if the latter is located in its catching position. If the releasing lever is actuated, the pawl or the blocking lever is thereby moved out of its blocking position if the releasing lever is not excessively accelerated. If excessively large accelerations of the releasing lever occur, as can be caused by a crash, then an arresting device of the lock prevents the releasing lever from being able to move the pawl or the blocking lever out of its blocking or latching position, respectively. The lock is therefore incapable of opening if the releasing lever is accelerated in the event of a crash.

Lock for a motor vehicle

An attachment element () connecting a locking bar () of a lock () of a motor vehicle to an actuation lever () of a motor vehicle lock (), wherein the attachment element () consists of one part and is C-shaped, and wherein the limbs () of the C-shape () are connected with each other in a hinge-type connection and are designed so that they can be connected positively and/or frictionally with an opening () of a lever ().
