Abstract
Official abstract text for this publication.
In a vehicle door latch, a motion restriction device is coupled to an auxiliary pawl that is connected to the pawl of a ratchet and pawl combination. The auxiliary pawl must be actuated by one or more release levers in order to actuate the pawl and release the ratchet from a striker-containing position and open the latch. Because the only criterion for selectively prohibiting movement of the auxiliary pawl is its speed, it is possible to prevent the latch from unintentionally opening in a crash situation regardless of the direction the inertial forces of the crash are applied to the latch or the release levers therein or the outside or inside handles.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle door latch, comprising: a housing; a ratchet mounted for pivotal movement in the housing, the ratchet moving between a latched position for retaining a striker and an unlatched position for releasing the striker, the ratchet being biased toward the unlatched position; a pawl mounted for pivotal movement in the housing, the pawl moving between an engaged position maintaining the ratchet in the latched position and a release position enabli…
