Motor vehicle lock

A motor vehicle, in particular a side door lock, comprising a locking mechanism leaving a rotary latch and at least one locking pawl, an actuating lever chain with at least one actuating lever and a release lever, wherein a blocked locking mechanism can be unblocked by means of the release lever, and a coupling element between the actuating lever and the release lever, wherein the coupling element can be actuated by means of a mass inertia element which is mounted in the motor vehicle lock, and wherein the mass inertia element can be stored in the motor vehicle lock by means of a plastic mandrel.

Lock for a motor vehicle

A drive unit for motor vehicle applications, in particular to a locking system drive unit. The latter has an enclosure consisting substantially of a housing and cover. In addition, an electric motor is realized inside the enclosure. The electric motor is receiving with its two motor bearings in associated cutouts in the housing and is fixed by joining together the housing and the cover. According to the invention, the housing and/or the cover have/has fixing anchors in a central region that are arranged on both sides of the cutouts.

A lock for a motor vehicle, in particular a side door lock, comprising a locking mechanism having a rotary latch and at least one locking pawl, an actuating level chain with at least one actuating level and a release lever, wherein a blocked locking mechanism can be unblocked by means of the release lever, and a coupling element between the actuating lever and release lever, wherein the coupling element can be actuated by means of a mass inertia element which is mounted in the motor vehicle lock, and wherein the mass inertia element can be stored in the motor vehicle lock by means of a plastic mandrel.

A locking device for a motor vehicle comprising an actuator, a lock with a locking mechanism, comprising a rotary latch and at least one pawl, the actuator and the lock can be interconnected by a Bowden cable and the Bowden cable has provision for actively blocking a force transmitted by the Bowden cable.

Locking device for a motor vehicle

A motor vehicle door lock, comprising a locking mechanism, which essentially consists of a rotary latch and a pawl, and further comprising an actuation lever mechanism acting on the locking mechanism, and an inertia element. Said inertia element, during normal operation, follows a movement of the actuation lever mechanism. At high accelerations, for example in the event of a crash, the inertia element blocks the actuation lever mechanism acting on the locking mechanism. According to the invention, an elastic damping element is connected to the actuation lever mechanism. Said damping element abuts the inertia element at least in the event of a crash for the purpose of damping vibrations.

Motor vehicle door lock

The aim of the invention is to provide a lock for a motor vehicle, whereby the accidental opening of said lock is prevented. To achieve this aim, a lock comprises a locking mechanism with a rotary latch and a locking pawl for arresting the rotary latch in a latch position. In order to open the lock with minimum effort, an electric drive () is provided by means of which drive the locking pawl can be moved directly or indirectly out of its locking position. The lock is further provided with a movable blocking pawl (), which can impede the electric drive () from opening the lock. For the locking mechanism to be electrically opened, the blocking pawl () needs to be moved out of its blocking position and the electric drive () needs be to actuated.

A method of forming a motor vehicle door lock includes arranging a lever, providing an electric drive that pivots the lever to place the motor vehicle door lock in an open state and includes a motor and a wheel gear that is driven by the motor and has a circumferential face, forming at least one damping stop on the wheel gear that protrudes axially from the circumferential face of the wheel gear and extends from the circumferential face toward a stop plane that is spaced from and parallel to an actuating plane in which the wheel gear and the lever are rotatable, providing a housing stop surface that is engageable by the damping stop along the stop plane in a rotational direction of the wheel gear, and forming the damping stop and the wheel gear as a single piece using a two-component injection molding process.

The invention relates to a motor vehicle door lock, which is equipped with a ratchet mechanism, at least one actuation lever for triggering 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 the event of an accident ('in the event of a crash'). According to the invention the ratchet lever is mounted eccentrically on the axis thereof and thereby produces in dependence of the occurring retarding forces a counter-torque that blocks the actuation lever.

The aim of the invention is to provide a locking mechanism for a lock, which can be opened quietly. To achieve this aim, a lock is proposed comprising a locking mechanism with a rotary latch, a locking pawl for locking the rotary latch in a detent position and a braking pawl which initially can brake a rotary motion of the rotary latch that occurs after or during a movement of the locking pawl out of its detent position. Opening sounds can be reduced by means of this initial braking action. The lock also comprises a driving dog mechanism with a translatory action that can lift the braking pawl out of its braking position. This ensures that the braking pawl is moved out of its braking position in a reliable manner so that the lock can be opened.

Motor vehicle lock comprising a braking pawl and a driving dog mechanism

The invention relates to a lock, in particular for a door or opening element of a motor vehicle. In order to avoid the unplanned opening of the lock in the event of a crash, the invention proposes a lock with a locking mechanism comprising a rotary latch, a pawl for locking the rotary latch in a detent position, preferably a blocking lever for blocking the pawl in the detent position and a release lever for opening the locking mechanism, in particular by lifting the blocking lever out of the blocking position. The lock is provided with a rotation-lock device, by means of which an opening process of the locking mechanism caused by momentum or an impact can be prevented or blocked.

The invention relates to a lock, in particular for a door or opening element of a motor vehicle, said lock comprising a locking mechanism with a rotary latch, a pawl for locking the rotary latch in a detent position, preferably a blocking lever for blocking the pawl in the detent position and a release lever for opening the locking mechanism, in particular by moving the blocking lever out of the blocking position. The lock is characterized in that a safety catch device of the lock, said device comprising in particular more than one catch position, is designed to prevent the opening of the locking mechanism during excessive acceleration, in particular during excessively violent acceleration of the release lever and/or handle of a door or opening element. An unplanned opening of the lock in the event of a crash can thus be avoided.

The invention relates to a motor vehicle component support, in particular a motor vehicle door lock (), and to a method for the production thereof. Said motor vehicle component support is equipped with a strip conductor structure () composed of several strip conductors (). According to the invention, the strip conductor structure () comprises at least two conductor strip sub-structures () which are electrically interconnected by means of at least one connecting element () which is applied later.
