Abstract

Disclosed herein are embodiments of a latching mechanism for a vehicle seat. An exemplary latching mechanism for allowing selective attachment and detachment of a vehicle seat comprises a latch configured for latching and unlatching the seat, the latch being biased to a latched condition. The latching mechanism also comprises a lock for locking the latch and releasing the latch, the lock having a locked position, a transition position and a release position and configured for movement from the locked position to the release position through the transition position. The latching mechanism further comprises an indicator responsive to the position of the lock and configured to activate indication that the latch is released when the lock is moved through the transition position.

Claims

1. A latching mechanism for allowing selective attachment and detachment of a vehicle seat, comprising:

a latch configured for latching and unlatching the seat, the latch being biased to an unlatched condition;

a lock for locking the latch and releasing the latch, the lock having a locked position, a transition position and a release position and configured for movement from the locked position to the release position through the transition position, wherein on movement of the lock to the release position, the latch is biased for independent movement relative to the lock from a latched condition to the unlatched condition; and

an indicator responsive to the position of the lock and configured to activate indication that the latch is released only upon movement of the lock through the transition position.

2. The latching mechanism of claim 1, further comprising:

an operator input, the lock responsive to the operator input to lock and release the latch.

3. The latching mechanism of claim 2, wherein the indicator and the operator input are both situated on a rear surface of the vehicle seat.

4. The latching mechanism of claim 1, wherein the indicator is configured for selective positioning to indicate at least one of a locked state and a released state of the latch.

5. The latching mechanism of claim 4, wherein the indicator is configured to be visible to a user to indicate the released state and is configured to be not visible to the user to indicate the locked state.

6. The latching mechanism of claim 1, wherein the indicator is biased towards a first position indicative of a locked state of the latch and is coupled to the lock such that movement of the lock through the transition position urges the indicator towards a second position indicative of a released state of the latch.

7. The latching mechanism of claim 1, wherein the indicator faces a direction that is perpendicular to a rotational axis of the latch.

20. The latching mechanism of claim 1, wherein the lock is configured for selective engagement with the latch for locking the latch and releasing the latch, the latch is configured for movement from a latched condition to the unlatched condition in a first rotational direction about a first rotational axis, the lock is configured for movement from the locked position to the release position through the transition position in a second rotational direction about a second rotational axis, and the first rotational axis is parallel to the second rotational axis and the first rotational direction is opposite to the second rotational direction.

8. A seat for a vehicle, comprising:

a latch configured for movement between a latched condition and an unlatched condition in a first rotational direction about a first rotational axis, the latch being biased for movement towards the unlatched condition;

a cam configured for selective engagement with the latch for selectively maintaining the latch in a locked state wherein the latch is locked in the latched condition and a released state wherein the latch is released from the latched condition, wherein the cam is configured for movement from a locked position to a release position through a transition position in a second rotational direction about a second rotational axis, wherein the first rotational axis is parallel to the second rotational axis and the first rotational direction is opposite to the second rotational direction, the cam maintaining the latch in the locked state during movement from the locked position to the transition position and releasing the latch to the released state at the release position; and

an indicator responsive to movement of the cam to activate indication of the released state only upon movement of the cam through the transition position.

9. The seat of claim 8, wherein the cam is biased for movement towards the locked position.

10. The seat of claim 8, further comprising:

an operator input, the cam responsive to the operator input for movement from the locked position to the release position.

11. The seat of claim 10, wherein the indicator and the operator input are both situated on a rear surface of the seat.

12. The seat of claim 8, wherein the latch is configured for movement between the latched condition and the unlatched condition through selective engagement with a striker.

14. The seat of claim 8, wherein the indicator is configured for selective positioning to indicate at least one of the locked state and the released state of the latch.

15. The seat of claim 14, wherein the indicator is configured to be visible to a user to indicate the released state and is configured to be not visible to the user to indicate the locked state.

16. The seat of claim 8, wherein the indicator is biased towards a first position indicative of the locked state and is coupled to the cam such that movement of the cam through the transition position urges the indicator towards a second position indicative of the released state.

17. The seat of claim 16, wherein the indicator is configured to indicate the released state in response to a cam force applied by the cam when the cam urges the indicator towards the second position.

18. The seat of claim 8, wherein the indicator is situated both laterally and vertically spaced apart from the cam on a frame of the seat.

19. The seat of claim 8, wherein the indicator faces a direction that is perpendicular to the first rotational axis.

13. A seat for a vehicle, comprising:

a latch configured for movement between a latched condition and an unlatched condition, the latch being biased for movement towards the unlatched condition, wherein the latch is configured for movement between the latched condition and the unlatched condition through selective engagement with a striker;

a cam configured for selective engagement with the latch for selectively maintaining the latch in a locked state wherein the latch is locked in the latched condition and a released state wherein the latch is released from the latched condition, wherein the cam is configured for movement from a locked position to a release position through a transition position, the cam maintaining the latch in the locked state during movement from the locked position to the transition position and releasing the latch to the released state at the release position, wherein the cam engages the latch to prohibit movement of the latch out of engagement with the striker to maintain the latch in the locked state and disengages the latch to allow movement of the latch out of engagement with the striker to release the latch to the released state; and

an indicator responsive to movement of the cam to activate indication of the released state only upon movement of the cam through the transition position.
