Abstract
A vehicle latch is provided having a ratchet, a primary pawl, an auxiliary ratchet and a secondary pawl, and further including a gear that is movable to a secondary pawl locking position wherein the gear directly blocks movement of the secondary pawl and locks the secondary pawl in an auxiliary ratchet holding position to prevent premature or unintended opening of the latch.
Claims18
A vehicle latch, comprising:
- a ratchet movable between a striker capture position whereat the ratchet is positioned to retain a striker and a striker release position whereat the ratchet is positioned to release the striker, wherein the ratchet is biased towards the striker release position;
- a pawl movable between a ratchet holding position whereat the pawl is positioned to hold the ratchet in the striker capture position and a ratchet release position whereat the pawl permits the movement of the ratchet out of the striker capture position, wherein the pawl is biased towards the ratchet holding position;
- and
- a gear driven by an electric motor into a pawl locking position in which a gear locking surface on the gear directly blocks movement of a pawl locking surface on the pawl so that the gear directly holds the pawl in the ratchet holding position.

A vehicle latch, comprising:
- a ratchet movable between a striker capture position whereat the ratchet is positioned to retain a striker and a striker release position whereat the ratchet is positioned to release the striker, wherein the ratchet is biased towards the striker release position;
- a pawl movable between a ratchet holding position wherein the pawl is positioned to hold the ratchet in the striker capture position and a ratchet release position wherein the pawl permits the movement of the ratchet out of the striker capture position, wherein the pawl is biased towards the ratchet holding position;
- a gear that is operatively connected to the pawl, wherein the gear is rotatable to cause movement of the pawl towards the ratchet holding position, wherein the gear is rotatable to cause movement of the pawl towards the ratchet release position, wherein the gear is rotatable to a pawl locking position to lock the pawl in the ratchet holding position, and wherein the gear is rotatable to a reset position during which the gear causes movement of the pawl to the ratchet holding position;
- and
- a reset position sensor positioned to detect the presence of the gear in the reset position.

A vehicle latch, comprising:
- a housing;
- a ratchet mounted to the housing and movable between a striker capture position whereat the ratchet is positioned to retain a striker and a striker release position whereat the ratchet is positioned to release the striker, wherein the ratchet is biased towards the striker release position;
- a pawl mounted to the housing and movable between a ratchet holding position whereat the pawl is positioned to hold the ratchet in the striker capture position and a ratchet release position whereat the pawl permits the movement of the ratchet out of the striker capture position, wherein the pawl is biased towards the ratchet holding position;
- and
- a gear mounted to the housing for rotational movement about a gear axis, wherein the gear is movable to a first position in which the gear blocks movement of the pawl out of the ratchet holding position, wherein the gear is movable to a second position in which the gear holds the primary pawl in the ratchet releasing position, and wherein the gear is movable to a third position in which the gear allows the primary pawl to move toward its ratchet holding position.
