A latch assembly includes a chassis and a rotatable claw-type latch bolt moveably mounted on the chassis. The latch bolt has a closed position for retaining a striker and an open position for releasing the striker. The latch bolt is provided with a latch abutment remote from a center of rotation. The latch assembly further includes a pawl rotatable about a pawl axis and having an engaged position for holding the latch bolt in the closed position and a disengaged position that allows the latch bolt to move to the open position. The latch assembly includes an eccentric arrangement defining a first axis and the pawl axis remote from the first axis. The latch assembly also includes a reset lever rotatably fixed to the eccentric arrangement for mutual rotation with the eccentric arrangement about the first axis. The latch assembly includes a biasing lever configured to transmit a biasing force to the reset lever at a position remote from the first axis and to the latch bolt via the latch abutment. The latch assembly includes a biasing device arranged to apply the biasing force to the biasing lever. The latch assembly is configured such that when the pawl retains the latch bolt in the closed position, the biasing lever applies a force to the reset lever to promote disengagement of the pawl, and such that when the pawl is disengaged, the biasing lever promotes the rotation of the latch bolt into the open position.

A latch arrangement includes a power control system which can be energized to prevent opening of a door latch by controlling the movement of a release mechanism within a latch. A sensor monitors an operative state of the release mechanism. In the event the sensor detects an unauthorized attempt to open a door, the power control system is energized, thereby preventing unauthorized opening of the latch. The sensor can monitor the direct movement of a door handle. Additionally, or alternatively, the sensor can monitor an internal component within the release mechanism to monitor movements indicative of movement of the door handle.

A latch arrangement includes a lever movable in response to movement of a door lever. A controller is configured for selectively preventing movement of the lever. The controller includes a mono-stable blocking element in the form of a bi-metallic strip which can be operated such that a distal end acts to block movement of the lever. The controller also includes a bi-stable blocking element having a nib that can be moved to an extended position to block movement of the lever. Both blocking elements can be operated at the same time. When either of the blocking elements are arranged in the path of the release lever, unlatching of the door is prevented.

A latch assembly includes a chassis, a latch bolt moveably mounted on the chassis and having a closed position for retaining a striker and an open position for releasing the striker, a pawl having an engaged position at which the pawl is engaged with the latch bolt to hold the latch bolt in the closed position and a disengaged position at which the pawl is disengaged from the latch bolt, thereby allowing the latch bolt to move to the open position, an eccentric arrangement defining an eccentric axis and a pawl axis remote from the eccentric axis. The eccentric arrangement is rotatable about the eccentric axis, and the pawl is rotatable about the pawl axis. When the pawl moves from the engaged position to the disengaged position, the eccentric arrangement rotates in one of a clockwise and a counter-clockwise direction about the eccentric axis. With the pawl in the engaged position, a force applied to the pawl by the latch bolt creates a turning moment on the eccentric arrangement in the one of the clockwise and counter-clockwise direction, and the eccentric arrangement is prevented from rotating in said one of the clockwise and counter-clockwise direction by a moveable abutment.

A motor arrangement includes a rotor with a north rotor magnetic pole and a south rotor magnetic pole, the rotor being rotatable about a rotor axis between a first rotor position and a second rotor position. The rotor includes a first rotor abutment and a second rotor abutment. The motor arrangement includes a stator having a first stator magnetic pole and a second stator magnetic pole, the stator having a first stator condition in which the first stator magnetic pole is a north stator magnetic pole and the second stator magnetic pole is a south stator magnetic pole, and a second stator condition in which the first stator magnetic pole is a south stator magnetic pole and the second stator magnetic pole is a north stator magnetic pole. The first stator condition corresponds to the first rotor position in which the north rotor magnetic pole is proximate the second stator magnetic pole and the south rotor magnetic pole is proximate the first stator magnetic pole, and the second stator condition corresponds to the second rotor position in which the north rotor magnetic pole is proximate the first stator magnetic pole and the south rotor magnetic pole is proximate the second stator magnetic pole. The motor arrangement includes an output member rotatable about the rotor axis and having a first output abutment engageable by the first rotor abutment to move the output member in a first rotational direction and having a second output abutment engageable by the second rotor abutment to move the output member in a second rotational direction. The output member is rotatable relative to the rotor to a limited extent defined by the first and second output abutments and the first and second rotor abutments. The motor arrangement includes a first stop to limit movement of the rotor past the first rotor position and a second stop to limit movement of the rotor past the second rotor position.

A vehicle door module includes a door trim defining a plane and a window regulator rail separably fixed to the door trim. The rail is fastened to a door at a fastening point. A projecting line extends from the fastening point and perpendicular to the rail to intersects the plane outside the door trim A method for assembling the door module in a door includes introducing the window regulator rail into the shell of the vehicle door, fastening the fastening point to the shell, and separating the door trim from the rail. Access is not impeded by the door trim. The arrangement simplifies mounting of the window regulator to the door.

An eccentric reduction gear for a vehicle window winder system has a ring gear, a planet pinion that is eccentric relative to the ring gear, a drive component that drives the planet pinion and the ring gear so that they roll relative to each other, and a winding drum attached to the planet pinion. A transmission component is wound around the winding drum and drives a vehicle window. The reduction gear provides a high reduction ratio in a small space and also ensures that the movement cannot be reversed.
