A latching device for a backrest latch of a motor vehicle for the bolting and unbolting of seat backrests includes a locking mechanism having a catch and at least one pawl, and an unbolting element for the locking mechanism which can be acted on manually and/or mechanically, whereby the unbolting element is a component of an exchangeable unbolting module and whereby the unbolting module forms a latch housing together with a basic module accommodating the locking mechanism, whereby the unbolting element is formed as a multifunctional element and whereby at least a switching and/or attenuation function can be executed by the multifunctional element.

A motor-driven door ratchet includes a catch part configured to lock a vehicle door to a vehicle body by being caught by a striker mounted on the vehicle body. A door locking and release part includes a main motor and is configured to allow the catch part to be locked or released from the striker. An inside emergency operation lever is connected to an inside handle installed in the vehicle door and is configured to be rotated by receiving a manipulation force to allow the vehicle door to be opened by applying torque to the catch part. An outside emergency operation lever is connected to an outside handle installed in the vehicle door and is configured to be rotated by receiving a manipulation force to allow the vehicle door to be opened by applying torque to the catch part.

A latch actuator comprises a motor, a speed reduction gearing coupled to an output shaft of the motor, a spindle, and a motion conversion mechanism. The spindle has a threaded portion in engagement with the speed reduction gearing. The spindle is supported to be rotatable about an axis. The threaded portion is rotationally fixed relative to the spindle. The motion conversion mechanism is configured to cause a displacement of the spindle along the axis when the spindle rotates.

An actuator for a latch is provided, the actuator having: a motor operatively coupled to a gear train; and a sector gear pivotally mounted to the actuator and operatively coupled to the gear train, wherein rotational movement of the sector gear is translated into linear movement of a link operatively coupled to the sector gear and wherein linear movement of the link causes a linear movement of a portion of a lock lever operatively coupled to the actuator.

Coupler-actuator assembly for a powered latch system of a hatch lid of a storage compartment of a vehicle, the coupler-actuator assembly including: a housing adapted to be disposed partially or wholly within and coupled to the hatch lid of the storage compartment or the storage compartment itself; a motor disposed partially or wholly within and coupled to the housing; an actuation mechanism disposed within the housing and coupled to the motor; and one or more slider racks disposed partially or wholly within the housing and coupled to the actuation mechanism. The coupler-actuator assembly also includes one or more connecting rods coupled to the one or more slider racks. The coupler-actuator assembly further includes one or more latch assemblies coupled to the one or more connecting rods, wherein, when actuated, the one or more latch assemblies are adapted to release the hatch lid from/secure the hatch lid to the storage compartment.

The invention relates to a motor vehicle door lock which is equipped with a locking mechanism (1, 2) consisting of essentially a rotary latch (1) and a pawl (2), in addition to an actuating lever chain (4) and a locking unit (5, 6). Said motor vehicle door lock also comprises a security device (8, 9, 10) which can optionally set the actuating lever chain (4) and/or the locking unit (5, 6) in a non-functioning state/functioning state. According to the invention, said security device (8, 9, 10) is designed as a retrofitted module (8, 9, 10) which can be connected, according to requirements, to a base module (1-6 and 11), said module surrounding the largest part of the locking mechanism (1, 2), the actuating lever chain (4) and the locking unit (5, 6).
