  • Patent number: 6024389
    Abstract: A vehicle door latch has a latching mechanism and stiffness adjustment mechanism disposed in a housing. The housing includes a fishmouth slot for receiving a striker. The latching mechanism includes a fork bolt that moves between a latching position and an unlatching position. The fork bolt has a throat that is aligned with the throat of the housing for receiving the striker when the fork bolt is in the unlatching position and that captures the striker when the fork bolt is in the latching position. An overslam bumper has an elastomeric portion located at a rearward end of the housing slot. The elastomeric portion engages the striker and biases the striker against a surface of the throat of the fork bolt when the striker is captured. The elastomeric portion is preloaded by the stiffness adjustment mechanism that includes a flexible portion of the housing, an expandable bushing, a nut that slides in the bushing for expanding the bushing and an adjustment screw that screws into the nut.

  • Patent number: 5964487
    Abstract: A security door latching mechanism and complementary receiver are arranged to be installed within a door and a complementary door jamb. In the preferred embodiment, the installation takes place in a vehicle and the latching mechanism can be installed either in the door or in the door frame or jamb. The latching mechanism includes a plunger shaft which is arranged to extend from the door jamb into the receiver, and is forcibly maintained in the extended position until retracted by an electrical current provided to an actuator. This actuator is spring-driven to keep the plunger shaft in an extended position until provided with an electrical power to retract the plunger shaft. A wedge-shaped guide forces the plunger shaft to slide to the recess when the door is being closed. It is necessary to constantly maintain the electric power to the actuator in order to keep the plunger shaft retracted.

  • Patent number: 5730480
    Abstract: A lock device has a striker and a lock proper. The lock proper includes a base member having a striker receiving slot into which the striker can be led. A latch plate is pivotally connected to the base member. A locking plate is pivotally connected to the base member. A striker restraining member is pivotally connected through a pivot shaft to the base member. The striker restraining member is pivotal between a restraining position, where a contact edge thereof abuts against the striker, and a releasing position, where the contact edge disengages from the striker. Springs are employed for biasing the latch plate to pivot toward a stand-by position, biasing the locking plate to pivot toward a lock position, and biasing the striker restraining member to pivot toward the restraining position. A link mechanism is employed for causing the striker restraining member to take the restraining position when the latch plate and the locking plate take latching and lock positions respectively.

  • Patent number: 5520426
    Abstract: Objectional vehicle door opening and closing sounds are eliminated by dampening vibration in the vehicle door system. An integral dampener is positioned to engage the bolt of the door latch assembly reducing the resonation of the door opening's frame caused by release of the striker from the latch bolt. The integral dampener frictionally engages the bolt for an initial opening and final closing portion of the linear travel of the door. Once initial opening has occurred and the striker has returned to its normal door-open, no-load position, the integral dampener disengages from the bolt and the latch assembly operates in a conventional manner.

  • Patent number: 5067757
    Abstract: The Device is of the push pad type having a translating action rod which is biased in the latch bolt-extended position. An abutment is fixed to the action rod to receive thereagainst the extending plunger of a shock absorber which is removably coupled to an open guide base. The base is mounted on a base plate to support action rod operating bellcranks, and to support the action rod therein also. A shock absorber holder is clasped to the guide base, and the cylinder of the shock absorber, in which a viscous fluid is confined, is engaged by the holder to direct the plunger toward the abutment. In the depicted embodiment, the plunger resists retraction, to decelerate and damp the return of the push pad and action rod to their at-rest positions and, consequently, to suppress the operating noise of the panic exit device.

  • Patent number: 4986579
    Abstract: A vehicle door may sometime be positioned in a half-latched condition for bringing the door from this condition to a fully latched condition, a door closing device is actuated in such manner that a pawl is rotated by a motor so as to be fully engaged with a striker. Due to this rotation of the pawl, the door is also rotated towards the body. If a portion of material or other objects are unfortunately put between the body and the rotating the door, the transmission of the driving force from the motor to the pawl through a first member and a second member can be interrupted by actuating an inside-handle (an outside-handle) which is operatively connected to the first member. Thus, further movement of the door is prevented, thereby preventing further damage of the material or injury of the other objects.
