Abstract

A vehicle latch testing assembly includes a base, a latch assembly fixed to the base, a striker assembly configured to engage the latch assembly, and a strain gauge connected to the striker assembly. An operating member is connected to the strain gauge and pivotally connected to the base. The operating member is configured to move between a first position and a second position to apply a first force to the latch assembly.

Claims (51)

1. A vehicle latch testing assembly for testing vehicle door latching assemblies prior to installation within vehicles, the vehicle latch testing assembly comprising:

a base;

a latch assembly fixed to the base;

a striker assembly configured to engage the latch assembly;

a strain gauge connected to the striker assembly; and

an operating member connected to the strain gauge and pivotally connected to the base, the operating member being configured to move between a first position and a second position to apply a first force to the latch assembly by moving the striker assembly relative to the latch assembly,

the strain gauge being configured to determine the first force applied to the latch assembly.

2. The vehicle latch testing assembly according to claim 1 , wherein

the operating member is pivotally connected to the strain gauge such that the strain gauge moves substantially longitudinally along a longitudinal axis of the strain gauge when the operating member moves between the first and second positions.

3. The vehicle latch testing assembly according to claim 1 , wherein

the strain gauge is configured to be connected to a first side of the striker assembly and the operating member is configured to be connected to a first pivot point of the base such that the first force is applied along a first axis.

4. The vehicle latch testing assembly according to claim 3 , wherein

the strain gauge is configured to be connected to a second side of the striker assembly and the operating member is configured to be connected to a second pivot point of the base.

5. The vehicle latch testing assembly according to claim 4 , wherein

the first pivot point is spaced from the second pivot point.

6. The vehicle latch testing assembly according to claim 4 , wherein

the operating member is configured to move between a third position and a fourth position to apply a second force to the latch assembly.

7. The vehicle latch testing assembly according to claim 6 , wherein

the second force is exerted along a second axis.

8. The vehicle latch testing assembly according to claim 7 , wherein

the second axis is substantially perpendicular to the first axis.

9. The vehicle latch testing assembly according to claim 1 , wherein

a first end of the operating member is pivotally connected to the base.

10. The vehicle latch testing assembly according to claim 9 , wherein

a first handle is disposed at a second end of the operating member to facilitate operation of the operating member.

11. The vehicle latch testing assembly according to claim 10 , wherein

a second handle is non-movably connected to the base.

12. The vehicle latch testing assembly according to claim 1 , wherein

a first indicator light is electrically connected to a switch of the latch assembly, the first indicator light indicating an unlatched condition between the striker assembly and the latch assembly.

13. The vehicle latch testing assembly according to claim 12 , wherein

a second indicator light is electrically connected to a switch of the latch assembly, the second indicator light indicating a latched position between the striker assembly and the latch assembly.

14. The vehicle latch testing assembly according to claim 1 , wherein

the striker assembly includes a striker connected to a plate, the plate being configured to be movably disposed on a surface of the base.

15. The vehicle latch testing assembly according to claim 14 , wherein

a first length of the plate is less than a second length of the surface of the base, and a first width of the plate is less than a second width of the surface of the base.

16. A method of testing a vehicle latch assembly comprising the steps of:

mounting a latch assembly to a base;

connecting a strain gauge to a striker assembly;

connecting an operating member to the strain gauge and to a first pivot point of the base;

engaging the striker assembly with the latch assembly; and

pivoting the operating member to apply a first force in a first direction to the latch assembly by moving the striker assembly relative to the latch assembly;

determining the first force with the strain gauge.

17. The method of testing the vehicle latch assembly of claim 16 , further comprising

connecting the operating member to a second pivot point of the base; and

pivoting the operating member to apply a second force in a second direction to the latch assembly.

18. The vehicle latch testing assembly according to claim 17 , wherein

the second direction is substantially perpendicular to the first direction.

19. The vehicle latch testing assembly according to claim 17 , wherein

the operating member is disconnected from the first pivot point and is connected to the second pivot point without disengaging the striker assembly from the latch assembly.

20. The vehicle latch testing assembly according to claim 17 , wherein

the operating member is pivotally connected to the strain gauge such that operation of the operating member maintains an orientation between the striker assembly and the latch assembly.
