Abstract

A tow hook assembly is detachably mounted to a frame member of a vehicle. The tow hook assembly includes a housing and a tow hook. The housing has a front wall with a front surface and an aperture formed in the front wall. The tow hook at least partially extends through the aperture and is movable between an extended position and a retracted position, in the extend position the tow hook extends farther outward from the housing than in the retracted position. The tow hook is configured to move from the extended position to the retracted position upon application of a force exceeding a first threshold. The housing is configured to disengage from the frame member upon an application of a force exceeding a second threshold greater than the first threshold.

First claim

1 . A tow hook assembly detachably mounted to a frame member of a vehicle, the tow hook assembly comprising:
a housing; and a hook at least partially received within the housing and movable between an extended position and a retracted position, in the extended position the hook extends farther outward from the housing than in the retracted position, the hook configured to move from the extended position to the retracted position upon application of a force exceeding a first threshold.

2 . (canceled)

3 . The tow hook assembly of claim 1 , further comprising an energy absorbing member damping a force at which the hook moves from the extended position to the retracted position, wherein the energy absorbing member is provided between the hook and a rear wall of the housing, the rear wall of the housing being opposite a front wall of the housing.

4 . The tow hook assembly of claim 3 , wherein the energy absorbing member comprises a spring.

5 - 8 . (canceled)

9 . The tow hook assembly of claim 1 , further comprising a spring-loaded ball plunger extending from the hook and positionable within a recess formed in the housing when the hook is in the extended position, the spring-loaded ball plunger disengaging the recess when the force exceeding the first threshold is applied to the hook.

10 . The tow hook assembly of claim 1 , further comprising a deformable clip engaging the hook when the hook is in the extended position, the deformable clip disengaging the hook when the force exceeding the first threshold is applied to the hook.

11 . The tow hook assembly of claim 1 , wherein the hook is a tow hook.

12 . The tow hook assembly of claim 11 , wherein the housing includes a front wall having a front surface, an aperture formed in the front wall.

13 . The tow hook assembly of claim 12 , wherein, the tow hook is at least partially extends through the aperture.

14 . The tow hook assembly of claim 13 , wherein the housing is configured to disengage from the frame member upon an application of a force exceeding a second threshold greater than the first threshold.

15 . The tow hook assembly of claim 14 , wherein the frame member includes a pair of flanges extending downward in a vehicle vertical direction and removably engaging the housing, the housing disengages from the pair of flanges when the force exceeding the second threshold is applied to the tow hook.

16 . The tow hook assembly of claim 15 , further comprising a retention member damping a force at which the tow hook moves from the extended position to the retracted position, wherein the retention member extends from the front wall of the housing to the tow hook.

17 . The tow hook assembly of claim 16 , wherein the retention member comprises an elastic band.

18 . The tow hook assembly of claim 17 , wherein the tow hook includes a first end and a second end opposite the first end, the first end extending through the aperture, the second end having an outer diameter greater than an inner diameter of the aperture, the second end abutting against the front wall of the housing when the tow hook is in the extended position.

19 . The tow hook assembly of claim 18 , wherein the first end extends through the aperture at a first distance, the first distance being the distance between the first end of the tow hook and the front surface of the housing when in the extended position, and the first end extends through the aperture at a second distance, the second distance being the distance between the first end of the tow hook and the front surface of the housing when the tow hook is in the retracted position, the first distance being greater than the second distance.

20 . The tow hook assembly of claim 19 , further comprising a spring-loaded ball plunger extending from the tow hook and positionable within a recess formed in the housing when the tow hook is in the extended position, the spring-loaded ball plunger disengaging the recess when the force exceeding the first threshold is applied to the tow hook.
