  • 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.
