Abstract

A compartment latch is shown. It includes a fork bolt that moves between an open position and a closed position and a first detent lever that that cooperates with the fork bolt and that moves between a latched position and a released position. A support for holding the fork bolt and the detent lever is also provided. A second detent lever for biasing against the first detent lever when the first detent lever is in the released position is provided. The second detent lever is connected to the support at a hinge.

Claims

1. A latch comprising:

a fork bolt that moves between an open position and a closed position;

a first detent lever that that cooperates with the fork bolt and moves between a latched position and a released position;

a support for holding the fork bolt and the first detent lever; and

a second detent lever for biasing against the first detent lever when the first detent lever is in the released position, the second detent lever integrally molded to the support at a living hinge, the second detent lever being configured for movement between a first position and a second position, wherein the second detent lever is spring biased into the first position by only the living hinge and the second detent lever contacts the first detent lever when the first detent lever is in the release position and the second detent lever is in the first position thereby preventing movement of the first detent lever from moving from the released position to the latched position and wherein movement of the second detent lever from the first position to the second position is only facilitated by direct contact between a portion of the fork bolt and a portion of the second detent lever;

wherein the first detent lever and the fork bolt occupy a first plane and the second detent lever occupies a second plane; and

wherein the second detent lever has a stop portion extending therefrom and the first detent lever has a feature extending therefrom for engaging the stop portion.

2. The latch of claim 1, wherein at least a portion of the support is plastic and the hinge is a living hinge is also plastic.

3. The latch of claim 2, wherein the second detent lever includes a stop portion and the first detent lever includes a feature for engaging the stop portion.

4. The latch of claim 1, wherein the second detent lever includes a stop portion and the first detent lever includes a feature for engaging the stop portion.

5. The latch of claim 1, wherein the stop portion and the feature occupy the second plane.

6. The latch of claim 1, wherein the second detent lever is a cantilever extending from the support.

7. The latch of claim 6, wherein the cantilever includes a living hinge portion adjacent a first end and a stop portion adjacent a second end for engaging the first detent lever and wherein the second detent lever is configured for movement between a first position and a second position, wherein the second end engages the first detent lever in the first position and the wherein the second end does not contact the first detent lever when it is in the second position.

8. The latch of claim 7, wherein the first detent lever includes a feature for engaging a stop portion of the second detent lever and wherein the fork bolt has a feature for engaging cam surfaces of the second detent lever in order to move the second detent lever from the first position to the second position as the fork bolt moves between the open position and the closed position.

9. A latch comprising:

a fork bolt that moves between an open position and a closed position;

a first detent lever that cooperates with the fork bolt and moves between a latched position and a released position in a first plane;

a feature extending from the first detent lever and in a second plane;

a second detent lever, the second detent lever in the second plane; and

a stop portion extending from the second detent lever and in the second plane and biasing against the feature when the first detent lever is in the released position, the second detent lever being integrally molded with a housing of the latch by a living hinge and being configured for movement between a first position and a second position, wherein the second detent lever is spring biased into the first position by only the living hinge and the stop portion contacts the feature when the first detent lever is in the release position and the second detent lever is in the first position thereby preventing movement of the first detent lever from moving from the released position to the latched position and wherein movement of the second detent lever from the first position to the second position is only facilitated by direct contact between a portion of the fork bolt and a portion of the second detent lever;

wherein the first detent lever and the fork bolt occupy a first plane and the second detent lever occupies a second plane; and

wherein the second detent lever has a stop portion extending therefrom and the first detent lever has a feature extending therefrom for engaging the stop portion.

10. The latch of claim 9, wherein the second detent lever and the housing are formed from plastic.

11. A latch comprising:

a fork bolt that moves between an open position and a closed position;

a first detent lever that that cooperates with the fork bolt and moves between a latched position and a released position; and

a second detent lever for biasing against the first detent lever when the first detent lever is in the released position, the second detent lever integrally formed as part of a housing supporting the fork bolt and the detent lever, the second detent lever being configured for movement between a first position and a second position, wherein the second detent lever is spring biased into the first position by only a portion of the second detent lever integrally formed with the housing and the second detent lever contacts the first detent lever when the first detent lever is in the release position and the second detent lever is in the first position thereby preventing movement of the first detent lever from moving from the released position to the latched position and wherein movement of the second detent lever from the first position to the second position is only facilitated by direct contact between a portion of the fork bolt and another portion of the second detent lever;

wherein the first detent lever and the fork bolt occupy a first plane and the second detent lever occupies a second plane;

wherein the second detent lever has a stop portion extending therefrom and the first detent lever has a feature extending therefrom for engaging the stop portion; and

wherein a portion of the second detent lever is a living hinge.

12. The latch of claim 11, wherein the second detent lever is cantilevered from the housing at the portion of the second detent lever.

13. The latch of claim 11, wherein the second detent lever, the housing and the living hinge are formed from plastic.
