  • Patent number: 4969672
    Abstract: A deck lid release actuator in which a uni-directional motor is mounted on a housing and rotatably drives a screw having high lead threads. The screw is rotatably journaled in a housing and a saddle nut threadedly engages the high lead threads of the screw so that rotation of the screw drives the saddle nut along the screw. An actuator member operably engages the detent lever of the deck lid latch and is mounted on the housing by a slide track extending parallel with the screw. When energization of the motor turns the screw, the saddle nut abuts against the actuator member to move the actuator member along the slide track and unlatch the deck lid latch. A spring acts on the actuator member to return the actuator member along the slide track thereby pushing the saddle nut axially along the screw as permitted by rotary back-drive of the screw and motor by the effort of the spring.

  • Patent number: 4875723
    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.

  • Patent number: 4869537
    Abstract: Mechanism for pulling an opened compartment panel closed and engaging a latch with a striker includes a slide member mounted on the body for horizontal reciprocating movement and having a cam slot which receives a cam follower carried by the striker so that horizontal reciprocating movement of the slide member vertically reciprocates the striker. The cam slot includes an inclined cam surface effective to provide the vertical reciprocation of the striker. The cam slot also includes a horizontal dwell surface at the end of the inclined surface to define the retracted position of the striker in which the compartment panel is closed so that the load imposed on the compartment lid in the direction to pry open the compartment panel is prevented from urging the slide member in a direction which would permit the striker to extend.

  • Patent number: 4861089
    Abstract: A venting arrangement for an automotive vehicle is provided in which its rear closure is automatically raised to a slightly open position in response to opening a door of the vehicle so that upon closing the door, entrapped air in the vehicle can escape through the rear to reduce door closing effort. The arrangement includes a latch and pull down mechanism for the rear closure of the vehicle to move the same between a partially open and a closed position and a control means including door jamb switches for energizing the pull down unit to raise the rear closure to its partially open position in response to opening movement of the door and to return the same to its fully closed position in response to closing of the door.

  • Patent number: 4850140
    Abstract: A releasable connection device for connecting a motor driven drive cable to a closure includes a pin attached to the closure and having a head supported by a necked down stem. A cylindrical housing member has an opening in a lateral wall thereof which receives the pin. A slide member is attached to the drive cable and is reciprocably carried by the housing member. The slide member has an open ended slot smaller than the head of the pin and receiving the necked down stem. A spring acts between the housing member and the slide member to urge the members to relative positions in which the head of the pin is captured to effect a connection between the drive cable and the closure. The spring yields upon imposition of force to permit energy absorbing limited relative movement between the members and yields further to permit withdrawal of the open ended slot of the slide member beyond the head of the pin so that the pin is released from the housing member.

  • Patent number: 4823059
    Abstract: A control for a motorized deck lid pull down mechanism which does not require the use of mechanically activated limit switches for detecting deck lid positions or the presence of closing or sealing obstructions. Detection of specified pull down conditions as well as the presence of deck lid obstructions is achieved by monitoring the magnitude of motor current in relation to various predefined motor current thresholds. Engagement of the deck lid with obstructions during the pull down sequence will cause the motor current to exceed the closing and sealing thresholds, terminating or reversing the respective function.

  • Patent number: 4796916
    Abstract: Each vehicle door in which a retractor is mounted includes a jamb switch mounted in the door jamb for sensing actual opening of the door, and a lock switch mounted in the door lock assembly for sensing actuation of the interior or exterior door handles. When door opening or closure is indicated, locking of the retractors is inhibited for a predetermined interval. Logical agreement between the lock and jamb switches is required to maintain the inhibit beyond the predetermined interval while the door is open. If agreement is not achieved within the interval, a switch failure is presumed, and the inhibit is removed to permit normal locking of the retractors. If such agreement is achieved, the inhibit is maintained until closure of the door, and thereafter for another predetermined interval. If the switches fail to remain in agreement after closure of the door, further operation of the inhibit on subsequent opening of the door is disabled.

  • Patent number: 4746153
    Abstract: A vehicle body compartment is selectively closed by a spring loaded closure panel movable between an open position and a closed position. A latch assembly is mounted on the panel and has a latch bolt spring biased to an unlatched position and normally maintained in the latched position by a key releasable detent lever. A pull down mechanism includes a housing mounted on a vehicle body and a striker mounted thereon by a motorized vertically reciprocating drive unit for moving the striker between extended position and a retracted position. When the panel is moved toward the closed position, the latch bolt engaes with the extended striker to interconnect the panel with the striker. The drive unit is energized and retracts the striker, thereby pulling the panel to its fully closed position. A cam acts between the detent lever of the latch assembly and the housing of the pull down mechanism.
