Abstract

A vehicle compartment latch has a support that is fastened to a deck lid. A fork bolt is pivotally attached to the support and moved from an unlatched position to a latched position by a striker when the deck lid is closed. The fork bolt is held in the latched position by a moveable detent lever that is moved to a release position to release the fork bolt so that the deck lid can be opened. The closure latch includes a detent lock-out that holds the detent lever in the release position until the deck lid is opened once the fork bolt is released. The detent lock out includes a striker position lever that is moved to an engaged position by the striker being retained by the fork bolt and a detent pawl that holds the detent lever in the released position once the detent lever is released.

Claims

1. A vehicle compartment latch comprising:

a support that is adapted for fastening to a closure,

a fork bolt that is attached to the support for movement between an unlatched position and a latched position,

a detent lever that is attached to the support for movement between a detent position and a release position, the detent lever retaining the fork bolt in the latched position when in the detent position and releasing the fork bolt for return to the unlatched position when in the release position, and

a detent lock-out that is attached to the support for movement between a disengaged position and an engaged position, the block-out holding the detent lever in the release position when in the engaged position.

2. The vehicle compartment latch as defined in claim 1 wherein the detent block out comprises a striker position lever that is attached to the support and a detent pawl that is attached to the striker position lever for movement between a cocked position and the engaged position where the detent pawl holds the detent lever in the release position.

3. The vehicle compartment latch as defined in claim 2 wherein the striker position lever is a bell crank lever that has an elongated arm that overlaps the fork bolt and a second arm, the detent pawl being attached to the second arm.

4. A vehicle compartment latch comprising:

a support that is adapted for fastening to a closure, a fork bolt that is attached to the support for movement between an unlatched position and a latched position, the fork bolt being spring biased toward the disengaged position,

a detent lever that is attached to the support for movement between a detent position and a release position, the detent lever being spring biased toward the detent position and retaining the fork bolt in the latched position when in the detent position, the detent lever releasing the fork bolt for return to the unlatched position when in the release position,

a detent lock-out that is attached to the support for movement between a disengaged position and an engaged position, the block-out holding the detent lever in the release position when in the engaged position, and

the detent lock-out including a striker position lever that is attached to the support and spring biased toward the disengaged position, and a detent pawl that is attached is to the striker position lever for movement between a cocked position and the engaged position with respect to the striker position lever where the detent pawl holds the detent lever in the release position, the detent pawl being spring biased toward the disengaged position and toward the cocked position with respect to the striker position lever.

5. The vehicle compartment latch as defined in claim 4 wherein the striker position lever is a bell crank lever that has an elongated arm that overlaps the fork bolt and a second arm, the detent pawl being attached to the second arm.

6. A vehicle compartment latch comprising:

a support that is adapted for fastening to a closure,

a fork bolt that is pivotally attached to the support for movement between an unlatched position and a latched position, the fork bolt being spring biased toward the disengaged position, the fork bolt having a latch shoulder and being adapted to receive a striker and retain the striker in the latched position,

a detent lever that is pivotally attached to the support for movement between a detent position and a release position, the detent lever being spring biased toward the detent position and having a catch that engages the latch shoulder of the fork bolt to retain the fork bolt in the latched position when in the detent position, the detent lever releasing the fork bolt for return to the unlatched position when in the release position, and

a detent lock-out for holding the detent lever in the release position that includes a bell crank lever and a detent pawl,

the bell crank lever being pivotally attached to the support for movement between a disengaged position and an engaged position, and spring biased toward the disengaged position,

the bell crank lever having an elongated arm that overlaps the fork bolt for pivoting the bell crank lever to the engaged position responsive to a striker being retained by the fork bolt, and a second arm,

the detent pawl being pivotally attached to the second arm of the bell crank lever for movement between a disengaged position, an intermediate cocked position and an engaged position, the detent pawl being spring biased toward the disengaged position and toward the intermediate cocked position with respect to the bell crank lever,

the detent pawl holding the detent lever in the release position when the bell crank lever is in its engaged position and the detent pawl is in its engaged position.

7. The vehicle compartment latch as defined in claim 6 wherein the detent pawl has a hook that engages an end of the catch of the detent lever to hold the detent lever in the release position.

8. The vehicle compartment latch as defined in claim 7 wherein the detent lever is released by the detent pawl when the fork bolt returns to the unlatched position.
