Abstract: An improved latch assembly (14) is provided for securing a vehicle door (12) in a closed position. Specifically, in one embodiment, the improved latch assembly (14) is intended to secure a first door fastener (16) to an opposing second door fastener (18) when the vehicle door (12) is subjected to a substantial acceleration. In this embodiment, the improved latch assembly (14) includes a release lever (26) coupled to the first door fastener (16). This release lever (26) is intended to selectively disengage the first door fastener (16) from the opposing second door fastener (18) thereby releasing the vehicle door (12) from its closed position. The Improved latch assembly (14) further includes an inertia-actuated detent lever (38) that is intended to block a predetermined path of the release lever (26) and prevent the release lever (26) from unlatching the vehicle door (12) from its closed position.
