Abstract

A fuel housing assembly for a vehicle includes a fuel door. A primary fuel door lock system includes a locking shaft having a locked configuration where a locking end of the locking shaft engages a locking member of the fuel door to inhibit opening of the fuel door and an unlocked configuration where the locking end of the locking shaft is removed from the locking member to allow opening of the fuel door. A secondary fuel door lock system is connected to the locking shaft by a decoupling structure that allows movement of the locking shaft between the locked and unlocked configurations relative to the secondary fuel door lock system.

First claim

What is claimed is:

1. A fuel housing assembly for a vehicle, comprising:
a fuel door;
a primary fuel door lock system comprising a locking shaft extending in a first direction, the locking shaft having a locked configuration where a locking end of the locking shaft engages a locking member of the fuel door to inhibit opening of the fuel door and an unlocked configuration where the locking end of the locking shaft is removed from the locking member to allow opening of the fuel door; and
a secondary fuel door lock system that is connected to the locking shaft by a decoupling structure that allows movement of the locking shaft between the locked and unlocked configurations relative to the secondary fuel door lock system;
wherein the decoupling structure comprises a loop portion, the loop portion receiving a connector component comprising a connecting portion extending outwardly from the locking shaft in a second direction, wherein the second direction is different from the first direction, wherein the connector component further comprises an enlarged head portion and a positioning paddle, and wherein the positioning paddle is connected to the locking shaft via the connecting portion and the positioning paddle extends outward along a lengthwise direction of the loop portion beyond the enlarged head portion.

2. The fuel housing assembly of claim 1 , wherein the secondary fuel door lock system comprises a release cable, the decoupling structure located on the release cable.

3. The fuel housing assembly of claim 2 further comprising an actuator that applies a force for locating the locking shaft in the locked and unlocked configurations;
wherein the force applied by the actuator for locating the locking shaft in the locked and unlocked configurations is offset from a force applied by the release cable for locating the locking shaft in the locked and unlocked configurations; and
wherein the force applied by the actuator is substantially parallel to the force applied by the release cable.

4. The fuel housing assembly of claim 1 , wherein a clearance is provided between the connector component and a distal end of the loop portion with the locking shaft in the locked configuration.

5. The fuel housing assembly of claim 1 , wherein a clearance is provided between the connector component and a proximal end of the loop portion with the locking shaft in the unlocked configuration.

6. The fuel housing assembly of claim 1 , wherein the loop portion provides a slot having a length that is greater than a travel distance of the connector component measured between the locked configuration and the unlocked configuration.

7. The fuel housing assembly of claim 1 , wherein the loop portion is located between the enlarged head portion and the positioning paddle.

8. The fuel housing assembly of claim 7 , wherein at least one of the enlarged head portion and the positioning paddle has a width greater than a width of a slot formed by the loop portion.

9. The fuel housing assembly of claim 1 , wherein the primary fuel door lock system comprises an actuator for locating the locking shaft in the locked and unlocked configurations and the secondary fuel door lock system includes a release cable that is manually graspable by an operator for locating the locking shaft in the unlocked configuration.

10. The fuel housing assembly of claim 1 , wherein the enlarged head portion extends outwardly beyond the positioning paddle in the second direction.

11. A vehicle comprising:
a fuel door;
a primary fuel door lock system mounted within the vehicle comprising:
a locking shaft having a locked configuration where a locking end of the locking shaft engages a locking member of the fuel door to inhibit opening of the fuel door and an unlocked configuration where the locking end of the locking shaft is removed from the locking member to allow opening of the fuel door; and
an actuator for locating the locking shaft in the locked and unlocked configurations; and

a secondary fuel door lock system that is connected to the locking shaft by a decoupling structure, the secondary fuel door lock system including a release cable that is manually graspable by an operator for locating the locking shaft in the unlocked configuration;
wherein the decoupling structure comprises a loop portion, the loop portion receiving a connector component extending outwardly from the locking shaft, the connector component comprising an enlarged head portion and a positioning paddle that extends outward along a lengthwise direction of the loop portion beyond the enlarged head portion.

12. The vehicle of claim 11 , wherein the decoupling structure is located on the release cable.

13. The vehicle of claim 11 , wherein a clearance is provided between the connector component and a distal end of the loop portion with the locking shaft in the locked configuration.

14. The vehicle of claim 13 , wherein a clearance is provided between the connector component and a proximal end of the loop portion with the locking shaft in the unlocked configuration.

15. The vehicle of claim 11 , wherein the loop portion provides a slot having a length that is greater than a travel distance of the connector component measured between the locked configuration and the unlocked configuration.

16. The vehicle of claim 11 , wherein the loop portion is located between the enlarged head portion and the positioning paddle.

17. The vehicle of claim 16 , wherein at least one of the enlarged head portion and the positioning paddle has a width greater than a width of a slot formed by the loop portion.

18. A vehicle comprising:
a fuel door;
a primary fuel door lock system mounted within the vehicle, the primary fuel door lock system comprising:
a locking shaft extending in a first direction, the locking shaft having a locked configuration where a locking end of the locking shaft engages a locking member of the fuel door to inhibit opening of the fuel door and an unlocked configuration where the locking end of the locking shaft is removed from the locking member to allow opening of the fuel door; and
an actuator mounted within the vehicle using a mounting bracket that locates the locking shaft in the locked and unlocked configurations; and

a secondary fuel door lock system that is connected to the locking shaft by a decoupling structure that allows movement of the locking shaft between the locked and unlocked configurations relative to the secondary fuel door lock system;
wherein the decoupling structure comprises a loop portion, the loop portion receiving a connector component comprising an enlarged head portion and a positioning paddle, wherein the positioning paddle is connected to the locking shaft via a first arm extending outwardly from the locking shaft in a second direction and a connecting portion extending outwardly from the locking shaft in a third direction, and wherein the first direction, the second direction, and the third direction are each different.

19. The vehicle of claim 18 , wherein the mounting bracket includes an opening that receives a release cable of the secondary fuel door lock system.

20. The vehicle of claim 19 , wherein the decoupling structure is located on the release cable, wherein a clearance is provided between the connector component and a distal end of the loop portion with the locking shaft in the locked configuration and wherein another clearance is provided between the connector component and a proximal end of the loop portion with the locking shaft in the unlocked configurati
