Patent number: 11519201Abstract: 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.Type: GrantFiled: February 2, 2018Date of Patent: December 6, 2022Assignee: Kiekert AGInventors: Carsten Fuchs, Dirk Eichel

Publication number: 20220003023Abstract: A motor vehicle lock, in particular a motor vehicle door lock, which has a locking mechanism consisting of a rotary latch and at least one pawl. The pawl exerts an opening torque (U1, U2) on the rotary latch. In addition, the pawl has an arched contact region, which interacts with a latching contour of the rotary latch. The contact region of the pawl has a first arch portion and a second arch portion, each having different radiuses (R1, R2). According to the invention, the first arch portion has, in the closing direction (S) of the locking mechanism, a larger radius (R1) than the second following arch portion having the radius (R2) there.Type: ApplicationFiled: September 24, 2019Publication date: January 6, 2022Inventor: Dirk EICHEL

Patent number: 10557289Abstract: 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.Type: GrantFiled: February 28, 2014Date of Patent: February 11, 2020Assignee: Kiekert AktiengesellschaftInventors: Hendrik Wahmann, Carsten Fuchs, Dirk Eichel

Patent number: 9879450Abstract: 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.Type: GrantFiled: February 14, 2014Date of Patent: January 30, 2018Assignee: Kiekert AktiengesellschaftInventors: Hendrik Wahmann, Dirk Eichel, Carsten Fuchs

Publication number: 20150354250Abstract: The invention relates to a motor vehicle door lock, which is equipped with a ratchet mechanism, a tripping lever for opening 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 an accident (“in the event of a crash”) ineffective. According to the invention the ratchet lever is connected to an actuating lever applying force to a tripping lever in such an articulated manner that both levers together in the normal operation describe a predetermined normal actuation track (R1) without mechanical blocking and in the crash operation describe a crash actuation track (R2) deviating from the normal actuation track (R1) while simultaneously a mechanical blocking occurs.Type: ApplicationFiled: December 18, 2013Publication date: December 10, 2015Inventors: Thorsten Bendel, Armin Handke, Carsten Fuchs, Matthias Ochtrop, Dirk Eichel, Omer Inan, Jan Faitl, Tomas Janacek

Patent number: 9109380Abstract: A motor vehicle door lock is provided with a catch with an actuating-lever mechanism which acts on the catch. There is also a locking lever which, together with the actuating lever, renders the actuating-lever mechanism inactive when accelerating forces of predetermined magnitude occur, for example in the event of a crash. The actuating lever and locking lever disable the actuating-lever mechanism mechanically, as a result of the accelerating forces occurring, by associated deflection. Following dissipation of the accelerating forces, the actuating lever and locking lever reconnect the actuating-lever mechanism.Type: GrantFiled: January 14, 2011Date of Patent: August 18, 2015Assignee: Kiekert AktiengesellschaftInventors: Stephan Mittelbach, Rolf Siemensmeyer, Dirk Eichel, Michael Strathmann
