20080303291 | LATCH SYSTEM - A latch system includes a latch bolt, a pawl for releasably retaining the latch bolt in a closed position, a first release member, a first transmission path connecting the first release member to the pawl, a second release member, and a second transmission path connecting the second release member to the pawl. A portion of the first transmission path and a portion of the second transmission path have a common portion, the common portion including a lock link having a first position at which the lock link completes the first transmission path and the second transmission path such that operation of either the first release member or the second release member opens a latch, and the lock link having a second position at which the lock link breaks the first transmission path and the second transmission path such that a single operation of either the first release member or the second release member does not open the latch. The latch system includes a first device capable of holding the lock link in the second position, a second device capable of holding the lock link in the second position, and a third device capable of holding the lock link in the second position. | 12-11-2008 |
20090173186 | DECLUTCHING MECHANISM - A declutching mechanism includes a chassis, a first gear rotatable relative to the chassis about a first gear axis fixed relative to the chassis, and a second gear selectively engageable with the first gear. The declutching mechanism includes an eccentric arrangement having a first shaft with a first shaft axis and a second shaft with a second shaft axis offset from the first shaft axis. The first shaft is non-rotatably fixed to the second shaft and selectively rotatably mounted in the chassis. The second gear is rotatably mounted on the second shaft. A holding feature selectively holds the eccentric arrangement in a first position. With the eccentric arrangement being held in the first position by the holding feature, the first gear and the second gear are in meshing engagement. With the eccentric arrangement being released by the holding feature, gear separating forces cause the eccentric arrangement to rotate about the first axis to a second position, thereby disengaging the first gear and the second gear. | 07-09-2009 |
20090174268 | HOLDING/RELEASING/RESETTING MECHANISM - A mechanism includes a movable member and a reluctance motor having an armature, a coil and two pole pieces, the armature being operably coupled to the movable member. The mechanism also has a first condition in which the reluctance motor is powered and the moveable member engages the pole pieces to magnetically hold the moveable member in a first position and a second condition in which the reluctance motor is unpowered and the moveable member is in a second position disengaged from the pole pieces. With the mechanism in the second position, powering of the reluctance motor causes the armature to rotate to drive the moveable member to the first position. | 07-09-2009 |
20090199605 | LATCH ASSEMBLY - 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. | 08-13-2009 |
20100032968 | MOTOR ARRANGEMENT - 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. | 02-11-2010 |

A separate unlocking arrangement is provided to temporarily override the child safety locking arrangement to allow opening of the rear passenger doors by their interior handles. The override, unlocking arrangement is operable by a driver and requires the simultaneous operation of the rear passenger door handle. The child safety locking arrangement is automatically reset upon release of the rear passenger door handle, without requiring any further action by the driver. | 02-12-2009 |
20090230703 | LATCH MECHANISM - A latch mechanism includes a latch chassis, a latch bolt having a closed position and an open position, a pawl having an engaged position at which the pawl holds the latch bolt in the closed position and a disengaged position at which the pawl allows the latch bolt to move to the open position, and a first release handle operably connected to the pawl via a transmission path to selectively move the pawl from the engaged position to the disengaged position. The transmission path includes a toggle linkage having a first link pivotable about a first axis and a second link pivotable about a second axis, the first link and the second link being pivotable relative to each other about a common axis. The latch mechanism includes a stop to limit rotation of the second link in a first direction relative to the first link. The toggle linkage has a first toggle linkage position where the common axis is positioned on a first side of a line joining the first axis and the second axis, and the stop is engaged to operably couple the first release handle with the pawl. The toggle linkage has a second toggle linkage position where the common axis is positioned on a second side of the line joining the first axis and the second axis to operably decouple the first release handle from the pawl. | 09-17-2009 |
20110260475 | LATCH ASSEMBLY - A latch assembly includes a chassis, a latch bolt, movably mounted on the chassis and having a closed position for retaining a striker and an open position for releasing the striker, and 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. The pawl is rotatably mounted via a pawl pivot pin about a pawl axis, and the pawl pivot pin includes a first arcuate portion having a first radius about the pawl axis. A cross-sectional area of the pawl pivot pin, taken perpendicular to the pawl axis, is greater than an area of a circle having the first radius. | 10-27-2011 |
