A latch assembly for a closure system having first and second closure members each movable between open and closed positions and method of operation are provided. The assembly includes a primary latch mechanism that has a primary actuation group to control actuation of the first closure member. The latch assembly also includes a secondary latch mechanism that has a secondary actuation group operable to control actuation of the second closure member. A controller unit is coupled to the primary and secondary actuation groups and determines which of the primary actuation group and the secondary actuation group to actuate and controls actuation of at least one of the primary actuation group and the secondary actuation group accordingly. The primary and secondary latch mechanisms, primary and secondary actuation groups, and controller unit are all integrated into the housing.

A motor vehicle lock in a fitted state interacts with a striker. The motor vehicle lock includes an adjustable catch and an adjustable locking pawl. The catch is adjustable into a main locking state and into an opening state, and the locking pawl is adjustable into an entry state, and into a lifted state. The motor vehicle lock includes a tensioning mechanism. When the catch is in the main locking state and the locking pawl is in the entry state, the tensioning mechanism can be brought into a tensioned state in which the tensioning mechanism introduces a mechanical preload into the catch in its opening direction. The tensioning mechanism can be brought into a relaxed state, in which the preload originating from the tensioning mechanism is reduced or cancelled.

In a door hinge device for the vehicle, in a vehicle without a B pillar, a hinge slider connected to a hinge portion of a door slides and moves in an external diagonal direction of a vehicle body along upper and lower rails by a driving torque of a motor inside a case, securing a rotation trajectory of the door, and then a striker fixed to the hinge slider is restrained by a latch portion fixed to the case to fix the slide movement position of the hinge slider, ensuring stability of the opening/closing operation of the door.

An embodiment vehicular door-opening-and-closing device includes a latch, a striker configured to be lockably fitted into the latch, and a magnet configured to maintain the striker in a state of being fitted into the latch. In an embodiment, the magnet has a magnetic force exceeding a repulsive force of a weather strip generated by compression of the weather strip, and the magnetic force exceeds the repulsive force in an initial operation of opening a vehicle door.

A closing device for a motor vehicle includes a locking mechanism having a rotary latch and at least one pawl, a trigger lever, with the locking mechanism being unlocked by the trigger lever, and a blocking component which is arranged on the closing device for blocking a movement of the trigger lever when a load acts on the motor vehicle from the outside. The blocking component can be guided in the closing device in a movable manner.

A motor vehicle locking system for a door or hatch, comprising a locking mechanism with a rotary latch and a pawl for latching the rotary latch, a drive pulley for an electrical opening means, which drive pulley can be rotated in a motorized manner in an operating direction for tripping the locking mechanism, and a return spring for rotating the drive pulley in the direction opposite the operating direction, wherein the drive pulley can be rotated in the operating direction without being influenced by the return spring or at least without spring load. Therefore, higher loads can be moved by the drive pulley.
