A motor vehicle lock, in particular a motor vehicle door lock, comprising a locking mechanism consisting essentially of a rotary latch and a pawl, further comprising an actuation lever chain for the locking mechanism, and comprising a locking element, at least one securing element, and exactly one spring element that cooperates with both the locking element and the securing element. The actuation lever chain can be controlled via the locking element to be put at least into the functional states 'unlocked' and “locked” and can be additionally controlled via the securing element to be put into the functional states “non-secured” and “secured.” According to the invention, the spring element additionally cooperates with the actuation lever chain.

Motor vehicle lock, in particular motor vehicle door lock

The invention relates to a motor vehicle lock, in particular a motor vehicle door lock, which is equipped with a locking mechanism () composed, essentially, of a rotary latch () and a pawl (). Furthermore, a securing device () and and an emergency actuation element () for the securing device are realized. The securing device () has at least one securing lever (), which can be acted upon both by a first motor drive () and by an emergency actuation lever () as part of the emergency actuation element (). According to the invention, the first securing lever () has a spring () for positioning the first securing lever.

Motor vehicle, in particular motor vehicle door lock

A motor vehicle lock includes a catch, a pawl, and a latch plate, wherein the catch and the pawl are rotatably supported on the latch plate, the latch plate has at least two openings for mounting the motor vehicle lock, and the latch plate has an inlet slot for a latch holder, and wherein a splay lying opposite the inlet slot is provided on the latch plate, wherein the splay has the form of a semicircle at least in an end region opposite the inlet slot.

Motor vehicle lock

The invention relates to a motor vehicle door lock () comprising: a lock housing (); an actuating nut () that is rotatably mounted in the lock housing (), the actuating nut () being mounted in the lock housing () such that said actuating nut can be rotated by an actuator acting externally on the actuating nut (); and a locking lever (), the locking lever () being displaceable by means of a rotation of the actuating nut (). The actuating nut () can be positioned in the lock housing by means of a housing cover ().

Motor vehicle door lock

The invention relates to a motor vehicle door lock comprising a locking mechanism consisting essentially of a rotary latch and a pawl, further comprising an actuation lever mechanism () that acts on the pawl, and a child safety device () that includes a child safety lever () to which the force of a spring () is applied. According to the invention, the child safety lever () and the spring () are designed as a subassembly ().

The invention relates to a lock for a motor vehicle or a building, said lock being equipped with a rotary latch () rotatably supported in the lock housing () about a locking bolt (), wherein the lock housing () has a slotted guide () for the locking bolt (), said slotted guide having at least one spring lip () on the insertion side, which spring lip reaches into the slotted guide and cushions the locking bolt (), said spring lip having creaking protection () that partially covers the surface () of the spring lip, wherein the spring lip () has a bounding bead () at the free end () and wherein the creaking protection () is designed as a sheet metal clamp () that can be attached to the spring lip () in front of the bounding bead with a preload.

Lock having a modified spring lip for motor vehicle doors

A lock for a motor vehicle door or hatch with a plastic lock housing () attached to the vehicle door or hatch, which is provided with a guide slot () for a latch bracket () or latch bolt and at least one spring lip (), attached at the entrance side of the guide slot () extending longitudinally therein and formed as a single piece with the lock housing, for elastically supporting the latch bracket () or latch bolt in the closed position of the lock as well as during insertion of the latch bracket () or latch bolt into and retraction of the latch bracket () or latch bolt out of the guide slot () and the catch (), and wherein at least one said spring lip () at least in a region of its free end, which free end corresponds to an end position and a support position () of the latch bracket () or latch bolt in the closed position of the lock, includes an overlay () having a low-friction, wear-resistant surface.

Lock for a motor vehicle door or hatch

A lock unit () comprising at least one catch (), a first pawl () with a pawl rotation axis (), and a blocking lever (), wherein in a locked state of the lock unit (), the catch () transfers a moment of rotation onto the first pawl () and the first pawl () is held in place by means of the blocking lever (), wherein a second pawl () is pivotably arranged on the pawl rotation axis () and is engageable with the blocking lever () and the catch (), and the first pawl () has a curved first blocking surface () for the primary position () of the catch ().

Lock unit having a multi-pawl locking mechanism

A motor-vehicle door latch has a housing, a part displaceable relative to the housing to release the latch, and mechanism on the housing operable to displace the part and release the latch. An actuating lever is pivotal on the housing between an unactuated position and an actuated position and a locking lever is also pivotal on the housing between a locked position coupling the actuating lever with the mechanism to displace same and an unlocked position uncoupling the actuating lever from the mechanism. Respective formations directly formed on the actuating lever and on the locking lever are directly engageable with each other for displacing the locking lever into the unlocked position on displacement of the actuating lever into the actuated position.
