  • Patent number: 6092845
    Abstract: A vehicle hood latch and release mechanism is latched when the hood striker engages the latch portion of the mechanism as the hood is moved to its closed position. The mechanism is actuated to release the hood striker by a pushing action on the cable or strand movable in the sheath of a cable assembly rather than by the typical pulling action on current hood releasing mechanisms. The pushing action is obtained with actuation of a hood latching and releasing control, by movement of a handle which operatively pushes on the cable or strand, transmitting a longitudinally compressive force rather than a longitudinally tensional force to the latch mechanism and moving that mechanism to the striker-released position. Release of the control permits one or more springs to cause the control handle to be returned to its position wherein the latching and release mechanism is ready to again be latched to the hood striker.

    Abstract: A lift-gate dual latch mechanism utilizing both a primary spring and an auxiliary spring operates to provide the additional force needed to release a striker member from both stop positions of a dual latch. Without the auxiliary spring as mentioned above, the lift-gate, being a heavy member typically stays in the latching mechanism when the lift-gate key is actuated to the open position. This requires additional lift forces, such as added springs between the lift-gate and the back panel of the vehicle to open the lift-gate from the mandated second lock position. Gas cylinders are shown to assist the opening of the lift-gate when required.

  • Patent number: 5269586
    Abstract: A sunroof, or like vehicle cover, is secured to a motor vehicle frame utilizing a latching mechanism which has a simple construction, low overall height, and reliable operation. An engagement element on the vehicle cover cooperates with a hook mounted to the vehicle frame by a guide pin received within a guide slot, and a pivot pin received within a reception slot. One of the slots is linear and the other is non-linear. The slots, pins, and hook are positioned with respect to each other and the engagement element so that as the hook moves from an unlatched position to a latched position, moving the engagement element toward the frame, it moves through an intermediate position in which the engagement element is closer to the volume defined by the frame than in the latched position. A resilient, compressible material is preferably provided between the cover and frame to accommodate movement through the intermediate position, and to bias the components to the latched position.
