Abstract: A brake caliper has a brake pad having a backplate with a friction material attached to one side and a loading face on an opposite side. The caliper further includes a piston that applies a force to the loading face. The brake pad is releasably attached to the piston, thereby eliminating a separate brake pad retaining structure in the caliper.

Abstract: An actuator includes an electromagnetic coil arrangement that is movable relative to a magnetic field generator between a first position and a second position of the actuator. The actuator is arranged such that when the actuator is in the first position, a pulse of current through the electromagnetic coil arrangement produces a region of magnetic field that repels the magnetic field generator from the first position and attracts the magnetic field generator towards the second position to move the actuator to the second position.

Abstract: A latch mechanism for a vehicle door includes a latch bolt, a pawl biased into engagement with the latch bolt to maintain the latch bolt in a latched condition, and a manual release lever for operable linkage to a vehicle door handle. A power release member is movable to displace the pawl from an engaged position where the pawl engages the latch bolt to a disengaged position where the pawl does not engage the latch bolt. A clutch member is mounted such that movement of the pawl causes movement of the clutch member. The clutch member is movable by the manual release lever between a first rest position at which a break is created in a transmission path from the power release member to the pawl and a second position at which power actuation of the power release member moves the pawl from the engaged position to the disengaged position.

Abstract: A lock mechanism for a vehicle door latch includes a lock actuator drivingly coupled to a lock link for movement of the lock link between a first position corresponding to a locked state of a latch and a second position corresponding to an unlocked state of the latch. The mechanism further includes a superlock actuator drivingly connected to a superlock link slidably mounted for movement of the superlock link between a third position corresponding to a superlocked state of the latch and a fourth position corresponding to a non-superlocked state of the latch. A fixed abutment surface and an inside lock lever are mounted such that movement of the lock link between the first and second positions may be achieved when the superlock link is in the fourth position. When the superlock link is the third position, the relative positions of the inside lock lever, the superlock link and the abutment surface prevent movement of the lock link between the first and second positions.

Abstract: A door latch mechanism for a vehicle comprising a release lever operable by a door handle and a transmission path linkage containing a resiliently biased inertia device. During normal operation, the inertia device is biased to form a transmission path that transmits an unlatching movement from the release lever to release a latch bolt of the latch. If an impact on the vehicle creates an acceleration force above a predetermined level, the inertia device moves to break the transmission path, preventing the latch from being unlatched.

Abstract: A latch of a vehicle door includes a retention plate having a shut face portion and a perpendicular inside face portion. The latch further includes a rotatable claw, a pawl resiliently biased into contact with the claw, and an intermediate release lever. The intermediate release lever has an axis of rotation substantially perpendicular to the axes of rotation of the claw and the pawl. During power release of the latch, a controller signals a power release actuator to rotate the intermediate release lever. The power release actuator is positioned in the plane of the inner face portion of the retention plate. As the intermediate release lever rotates, the cam surface of the intermediate release lever operatively rotates the pawl to disengage the claw and release the striker. If there is a failure of the power release mechanism, the mechanical linkage from the inside or outside door handle can be used to rotate the intermediate release lever and release the claw.

Abstract: A vehicle door latch assembly including a pivotally mounted latch claw having a mouth operatively co-acting with a striker as the door nears its closed position, a latching pawl self-engaging with the claw to hold it in latched condition retaining the door, and an unlatching mechanism selectively operable to disengage the latching pawl for opening the door. The unlatching mechanism includes a pawl lifter movable from a position of rest to carry the latching pawl out of engagement with the claw, a power output lever movable to engage and displace the pawl lifter from said position of rest, an input crank power actuated between first and second positions, a clutch releasably drive connecting the input crank to the output lever to cause shifting of the latter as the input crank moves to its second position, and an overriding link carrying the clutch into and out of drive connection.

Abstract: Vehicle door latch assembly includes power closing mechanism (FIG.1) for driving a latching claw 10 from an outer position at which it has engaged a coacting striker 14 for hold the related door at first-safety position to an inner position drawing the door to fully closed position, the claw being retained at either position by a conventional latching pawl 16 selectively releasable by unlatching means 20. The closing mechanism includes a drive pawl 24 pivoted on a powered drive lever 22 to turn the claw to the inner position, a disabling rocker 36 coupled to the arm latching means preventing engagement of the drive pawl when the latching pawl is disengaged so that release of the closed door is not obstructed.
