Abstract:
An actuating means for a vehicle body closure latch includes a driver or passenger controlled electric motor driving a reciprocable rack through a gear train. The rack is resiliently biased to a neutral position and shifts an actuator from neutral to an operating position when the rack is moved from the neutral position to a driving position. The actuator is engageable with a latch operator to control movement of the latch bolt to unlatched position when the actuator moves to an operating position. When the actuator reaches the operating position, the actuator is positively stopped to stall the motor or power operator. When the power is removed from the stalled motor or power operator by the driver or passenger releasing a switch, the bias of the resilient centering means returns the rack to its initial neutral or starting position and back drives the motor through the gear train.
Abstract:
A seat belt retractor has a reel for winding and unwinding a restraint belt and a winding spring urging winding rotation of the reel to tension the belt about the body of a seat occupant. A pawl is pivotally mounted for engagement with a ratchet wheel carried by the reel to prevent belt winding rotation and thereby relieve the tension on the belt. A spring acts on the pawl to normally urge the pawl toward engagement with the ratchet reel and goes overcenter upon predetermined movement of the pawl away from engagement with the ratchet wheel so that the spring holds the pawl in a disabled position. A control disc is connected to the reel by a friction clutch for rotation therewith and has a cam surface for controlling movement of the pawl into and out of engagement with the ratchet wheel and further cam surfaces for operating the pawl to and from the disabled position upon predetermined sequence of rotation of the control disc.

The drive unit also includes a flexible drive member having a plurality of spaced windows, an attachment assembly moveably attached to the guide channel, and an adjustable pulley assembly coupled to the guide channel that has a second pulley that rotates around a moveable pulley axis that can be adjusted to change the distance between the fixed pulley axis and the moveable pulley axis to take up slack in the flexible drive member.
Abstract:
An automotive vehicle has a power operated lift-gate that is opened and closed by two drive units. The typical drive unit has a guide channel, an attachment assembly that is disposed in the guide channel, a flexible drive member that is attached to the attachment assembly and formed in a loop for moving the attachment assembly in the guide channel. The flexible drive member is trained solely around two pulleys at the respective opposite ends of the guide channel to form the flexible drive member in a narrow loop. One of the pulleys is an idler pulley that is part of an adjustable pulley assembly and the other pulley is driven by a power unit that is attached to the guide channel. The adjustable pulley assembly adjusts the distance between the pulleys to take up slack in the flexible drive member.
Abstract:
A modular drive assembly for a sliding door, comprising: a guide track having a hinge slidably received therein; a pair of pulleys disposed on either end of the guide track; a pair of cables each having an end that is secured to the hinge and the other end is secured to a cable drum of a motor drive unit mounted to the guide track, the motor drive unit being configured to rotate the cable drum, wherein the cable drum is also capable of freely rotating within the motor drive unit when the motor drive unit is not rotating the cable drum, wherein rotation of the cable drum causes the hinge to move in the guide track as one of the cables wraps onto the cable drum while the other one of the cables wraps off of the cable drum.
Abstract:
A hinge assembly for coupling a sliding door of a vehicle to a drive unit for sliding the sliding door from an open position to a closed position, the drive unit causing the hinge assembly to slide within a guide track as the door moves between the open position and the closed position, the hinge assembly comprising: a first hinge portion; a second hinge portion, the first hinge portion being pivotally secured to the second hinge portion; a cable attachment being secured to the second hinge portion; and a guide surface disposed on a surface of the first hinge portion, the guide surface being configured to make contact with a portion of a cable having an end secured to the cable attachment when the second hinge portion is in a first orientation with respect to the position of the first hinge portion and the cable no longer makes contact with the guide surface as the second hinge portion moves from the first orientation to a second orientation with respect to the first hinge portion.
Abstract:
A vehicle door latch system including a deadbolt locking mechanism. The deadbolt locking mechanism is disengaged manually from outside the vehicle using the key cylinder. The manual deadbolt disengagement mechanism is effective in disengaging the deadbolt in the event of total vehicle power loss. The deadbolt mechanism includes a power driven rack.
Abstract:
A vehicle door check is provided including an arm connected with the door along a first end and with the vehicle along a second end, the arm adjacent the second end having a slot with first and second ends; a track of the vehicle for receiving the arm second end having a striker plate and an entrapment section; a rotary detent plate slidably mounted in the arm slot having its own first and second arms and a locking member; a spring for biasing rotation of the detent plate in a first angular direction and toward the slot first end; a contact surface fixed upon the arm interacting with the detent plate second arm whereby motion of the door from a closed position to a checked open position causes the detent plate locking member to contact the striker and pivot the detent plate in a second angular direction opposite the first angular direction and to move the detent plate toward the slot second end and wherein further movement of the door toward a checked open position causes the detent plate to pivot again in the first angular direction to place the locking member in the track entrapment section of the track with a low threshold of force on the door in the opening direction; and wherein the door is thereafter checked open even when the vehicle is on a declining surface toward the first end of the slot.
Abstract:
A hood latch engages a striker for latching a hood panel movable between open and closed positions relative to a body panel. The striker is mounted on one of the panels. A housing is mounted on the other panel. A pop-up lever is pivotally mounted to the housing for movement between lowered and raised positions. A pop-up spring bias the pop-up lever to the raised position. A latch lever has a hook for latching engagement with the striker. The latch lever is pivotally mounted to the pop-up lever for movement between latched and unlatched positions and has a handle for manually moving the latch lever. A latch spring acts between the pop-up lever and the latch lever to rotate the latch lever towards the latched position. A detent lever pivotally mounts to the housing for releasably engaging and retaining the pop-up lever in the lowered position and preventing rotation to the raised position. A detent spring acts between the detent lever and the housing for biasing rotation of the detent lever towards engagement with the pop-up lever. A cable is attached to the detent lever to rotate the detent lever away from engagement with the pop-up lever to release the pop-up lever from the lowered position. This release of the pop-up lever from the lowered position allows the pop-up spring to rotate the pop-up lever to the raised position. The latch lever and handle are then exposed to allow rotation of the handle.
Abstract:
A belt carriage is movable along a vehicle body mounted track to move an occupant restraint belt between an occupant restraint position and a stowed position permitting occupant ingress and egress. A plastic drive tape is attached to the carriage and has perforations which mesh with a toothed tape drive gear for driving the drive tape and carriage back and forth along the track. An electric motor and a speed reduction gear unit are connected to the tape drive gear by a clutch which couples with the drive gear only when the electric motor is energized so that whenever the electric motor is not energized the occupant may grip the belt carriage and manually move the belt carriage and the drive tape to move the restraint belt between the occupant restraint and stowed positions independently of the motor. The clutch is preferably a centrifugal clutch in which clutch pawls are thrown outwardly by centrifugal force to engage with the tape drive gear when the motor is energized.
