Patent number: 5520426Abstract: 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.Type: GrantFiled: September 12, 1994Date of Patent: May 28, 1996Assignee: General Motors CorporationInventors: Frank J.

Patent number: 5277461Abstract: A vehicle door latch has a fork bolt lever that is latched by a detent lever. The detent lever is operated by an intermittent lever that is operated by a transfer lever that is actuated by inside and outside door handles via operating levers. The door latch includes with a locking lever that disconnects the door handles from the intermittent lever when it is in the locked position. The door latch also includes an interlock between the intermittent lever and the locking lever that is automatically engaged in response to the position of the detent so that the door latch cannot be locked when the fork bolt lever is in an unlatched position. Consequently the door latch can only be locked when the door is closed and the fork bolt lever is in a latched position. This prevents the driver from locking his or her keys in the vehicle.Type: GrantFiled: December 24, 1992Date of Patent: January 11, 1994Assignee: General Motors CorporationInventors: Thomas A.
