  • Patent number: 11519201
    Abstract: 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.

  • Patent number: 11274474
    Abstract: 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 (1) 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 (2), which can impede the electric drive (1) from opening the lock. For the locking mechanism to be electrically opened, the blocking pawl (2) needs to be moved out of its blocking position and the electric drive (1) needs be to actuated.

  • Patent number: 11085211
    Abstract: 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.

  • Patent number: 10858868
    Abstract: 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.

  • Patent number: 10662681
    Abstract: 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.

  • Patent number: 10557289
    Abstract: 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.

  • Publication number: 20180073280
    Abstract: The subject of the invention is a motor vehicle door closure which is equipped with a motor vehicle door lock (1) and, interacting therewith, a lock holder with a locking bolt (2). Also provided is a locking mechanism (3, 4) which is arranged in the motor vehicle door lock (1) and consists substantially of a rotary latch (3) and a pawl (4). There is additionally an actuating lever unit (7, 8, 9) which acts on the locking mechanism (3, 4). The rotary latch (3) is mounted in and/or on a lock case (5, 6) so as to be rotatable about an axis (10). At the end of its running-in movement into the locking mechanism (3, 4) and in its locking position in the running-in direction (E), the locking bolt (2) is arranged at a (distance I) in front of the axis (10) of the rotary latch (3). According to the invention, the actuating lever unit (7, 8, 9) is mounted at least for the most part on the lock case (5, 6).

  • Patent number: 9879450
    Abstract: 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.
