Abstract

A hood latch release system for a vehicle. The hood latch release system may have a cable and a linkage. Deflection of the cable may actuate the linkage to unlatch the hood latch.

First claim

What is claimed is:

1. A hood latch release system comprising:
a cable having a first end fixedly disposed on a bumper beam and a second end;
a cable pusher that extends through an opening in the bumper beam; and
a linkage that couples the second end to a hood latch;
wherein the cable pusher engages the cable between the first and second ends and deflects the cable to unlatch the hood latch.

2. The system of claim 1 further comprising a fascia that is disposed proximate the bumper beam that actuates the cable pusher.

3. The system of claim 2 wherein the bumper beam includes first and second cable mounting features, wherein the cable is spaced apart from the bumper beam between the first and second cable mounting features.

4. The system of claim 2 further comprising a set of cable mounting rings that are fixedly disposed on the bumper beam, wherein the cable extends through the cable mounting rings.

5. The system of claim 2 wherein the first end is disposed between a bumper beam and a fascia that defines an exterior surface of the vehicle.

6. The system of claim 5 further comprising a set of cable mounting rings that are fixedly disposed on the fascia, wherein the cable extends through the cable mounting rings.

7. The system of claim 5 wherein deflection of the fascia causes the fascia to engage the cable between the first and second ends to actuate the linkage and unlatch the hood latch.

8. The system of claim 1 wherein the cable is in tension between the first end and the linkage.

9. The system of claim 1 wherein the linkage includes a first linkage end that is pivotally coupled to a pivot pin and a second linkage end disposed opposite the first linkage end that is connected to the hood latch.

10. The system of claim 9 wherein the cable is coupled to the linkage between the first and second linkage ends.

11. A system for unlatching a hood latch, comprising:
a bumper beam having an opening;
a cable pusher that is moveably disposed in the opening;
a linkage that is adapted to be pivotally disposed on a vehicle and that is connected to the hood latch;
a cable having a first end fixedly disposed on the bumper beam and a second end connected to the linkage; and
a fascia that is disposed proximate the bumper beam and that defines an exterior surface of the vehicle, wherein the bumper beam is disposed between the fascia and the cable;
wherein deflection of the fascia in response to a vehicle impact event actuates the cable pusher through the opening to deflect the cable and the cable pusher deflects the cable to actuate the linkage and unlatch the hood latch.

12. The system of claim 11 wherein the cable pusher remains stationary when the fascia engages the cable pusher and does not exert a threshold force on the cable pusher.

13. The system of claim 11 wherein the cable pusher is spaced apart from the fascia prior to the vehicle impact event.

14. A system for unlatching a latch comprising:
a bumper beam having an opening;
a fascia disposed proximate the bumper beam defining a vehicle exterior surface;
a cable pusher received in the opening; and
a cable disposed proximate the bumper beam and connected to the latch;
wherein the cable pusher moves through the opening to engage the cable to unlatch the latch when the fascia deflects to engage a first end of the cable pusher.

15. The system of claim 14 wherein the cable pusher has a second end disposed opposite the first end, wherein the second end has a concave indentation that receives the cable.

16. The system of claim 15 wherein the second end is spaced apart from the cable before the cable pusher is actuated with respect to the opening.

17. The system of claim 14 wherein the latch is a hood latch that selectively latches a hood of a vehicle.
