    Abstract

    A motorized moveable strike assembly is provided for a vehicle door. The assembly includes a strike on the door post which is moveable by an electric motor between extended and retracted positions. A latch on the door releasably engages the strike. A switch in the latch sends a signal to the controller to actuate the motor after the latch is engaged so as to retract the strike from the extended position to fully close the door. When the latch is disengaged from the strike, the latch switch sends a signal to controller to actuate the motor so as to extend the strike from the retracted position to the extended position as to prepare for the next door closing.

When the door is closed, the latch engages the strike, which is detected by the switch, which in turn sends a signal to the controller to actuate the motor. The motor rotates the torque wheel, which in turn moves the drive link and driven link, so as to pivot the pivot plate and thereby retract the strike approximately 1″. This retraction movement of the strike pulls the door tight to provide an enhanced seal between the door and the door frame. When the latch is released or disengaged from the strike by operation of the interior or exterior door handle to open the door, the switch in the rotary latch sends a signal to the controller to actuate the motor, which in turn rotates the torque wheel which moves the drive link and driven link, so as to pivot the pivot plate and thereby extend the strike approximately 1″, in preparation for the next closing of the door.

    [0088] The torque wheel can be rotated 360° by the motor, or in the case of a reciprocating motor the torque wheel is oscillated 180°, so as to extend and retract the strike.

    [0089] The distance that the strike is moved by the motor can be adjusted or fine-tuned by changing the extent of overlap between the drive link 7 and the driven link 6. The links 6, 7 have overlapping teeth 46, 47 to secure the links in a desired position via the link adjustment screw 5.

    [0090] The motor 10 is connected to a power supply of the vehicle independently of the rotary latch. Therefore, in case of a power failure, the latch can still be operated in a normal manner to open and close the vehicle door. Thus, a person cannot be locked in or locked out of the vehicle due to a lack of power to the motor, such as a dead battery.

    [0091] In the alternative embodiment shown is FIGS. 4-9, if the strike and latch assembly is subjected to longitudinal loading, the retention of the loading rivet 29 in the slot 30 of the pivot plate 3 facilitates retention of the pivot plate to the mount plate 1.

    [0092] The alternative embodiment shown in FIGS. 32-37 is a compact design that uses a motorized wheeled pin to move a strike bolt between door open and door closed positions. When the latch is closed on the strike, the wheeled pin moves the strike bolt between door open and door closed positions. When the latch is closed on the strike, the wheeled pin then pulls the strike into the door closed position. On release of the latch, the wheeled pin returns the strike to the door open position. Assembly allows adjustment for alignment of the body-mounted strike with the door-mounted latch jaws.

    [0093] When compared to the embodiments of FIGS. 1-30, the compact design reduces the space claim for the cinching mechanism by over 50% while increasing available strike travel by 25%. The compact design also adds separate vertical and horizontal adjustability of the strike relative to the door structure of the vehicle.

    [0095] The embodiment shown in FIGS. 38-39 is a way to remotely drive a vehicle door strike with an over center mechanism that is mounted on a mount bracket along with the drive motor, cam, drive rod and controller. The package would contain all items fully assembled and the timing of the cinch mechanism in relationship to the motor and inboard/outboard sensors would be adjusted before being sold to the customer.
