A door latch device which allows shared use of a connector for use in door latch devices equipped with standard electric components and a connector for use in door latch devices equipped with special electric components in addition to the standard electric components, thereby achieving an increase in the efficiency of the work of connecting to an external connector and a reduction in costs. A connector (32) of a standard switch plate (26) has a coupling hole (51) which penetrates, in the connecting direction of the external connector, a portion having no standard connecting terminals (304). The coupling hole (51) can be fitted with another switch plate (46) that allows the passage of electric current through electric components different than the standard electric components.

A handle for a motor vehicle includes a mounting carrier which can be secured on the inside of a door of the motor vehicle, a grip level that can be arranged on the outside of the door of the motor vehicle and is secured to said mounting carrier, and an activation element which is positioned movable on the mounting carrier. The mounting carrier comprises a control element that can be moved between a retaining position and a securing position. The control element engages with the activation element in the retaining position such that the activation element is retained in a mounting position in order to allow the grip level to be mounted more easily, and the control element is detached from the activation element when in the securing position.

A handle for a motor vehicle includes a mounting carrier which can be secured on the inside of a door of the motor vehicle, and a grip level that can be arranged on the outside of the door of the motor vehicle and is secured to said mounting carrier. A lock cylinder unit is mounted such that it can move on the mounting carrier, as a result of which the lock cylinder unit can be displaced between a pre-mounting position and a final mounting position.

A power supply device includes a boost convertor configured to perform a boost-up operation to boost a voltage supplied from an input terminal, a connection-assist diode connected in parallel to the boost convertor between the input terminal and an output terminal, and a switching element connected in parallel to the boost convertor and the connection-assist diode between the input terminal and the output terminal. A controller instructs the switching element to open and instructs the boost convertor to perform a boost-up operation for boosting the voltage at the input terminal during a boost-up period. The controller instructs the boost convertor to stop the boost-up operation when the boost-up period elapses. The controller then instructs the switching element to close the switching element. The controller then determines a state of the switching element based on a voltage at the output terminal detected. The in-vehicle power supply device can stably and accurately determine whether the switching element operates normally or not.

The disclosure relates to a door handle for a vehicle door which can be installed as such from the door inner side on a handle recess of the outer skin of the vehicle door, wherein the handle unit has a handle module and an especially elongate handle part which is accommodated by the handle module, wherein the handle module has a mechanism for the motorized adjustment of the handle part, wherein the handle unit can be pre-installed on the door. The door handle unit can have a fastening slide which, with the handle unit pre-installed is connected to the handle module on one side and to the motor vehicle door on the other side, wherein for the final installation of the door handle unit an installation movement can be introduced into the fastening slide by a tool in an installation direction from a narrow side of the vehicle door.

The invention relates to a door handle module (10) for a door handle unit (100) on a vehicle (200), in particular a commercial vehicle (200), said door handle module (10) being used to integrate an electronic unit (20) for the door handle unit (100). The door handle module (10) includes at least one covering element (11) on which at least one electronic element (21) of the electronic unit (20) is arranged, and at least one fastener (12), the door handle module (10) being securable to a module holder (110) on the door handle unit (100) by means of at least one fastener (12).

Disclosed are lock mechanisms for latch assemblies of vehicle compartment hoods, methods for making or using such lock mechanisms, and motor vehicles equipped with a multi-pull latch and lock system for releasably locking a hood assembly. A lock mechanism includes a gear that couples a closure latch to a latch release mechanism. The gear moves between a latched position, whereat the closure latch secures the closure in a closed position, and an unlatched position, whereat the gear transfers activation forces from the release mechanism to disengage the closure latch from the closure. A pawl is movable between a locked position, whereat the pawl engages and locks the gear in the latched position, and an unlocked position, whereat the pawl disengages the gear. An actuator is operatively engaged with a vehicle door to automatically move the pawl to the unlocked position responsive to movement of the door to an open position.

The present disclosure provides a vehicle back door device that improves workability when mounting a damper. The vehicle body-side mounting portion of the damper is positioned in a vehicle up-down direction and in vehicle front-rear direction relative to the bracket, by abutting an abutting piece provided at a vehicle body-side mounting portion of the damper against a positioning portion of a bracket. Further, by moving the abutting piece in a vehicle transverse direction, the vehicle body-side mounting portion of the damper can be supported by a pin of the bracket.
