Abstract

A cable release system configured to actuate a latch mechanism includes a cable arrangement configured to shift in response to an actuation force. The shifting of the cable arrangement is thereby configured to actuate the latch mechanism. The cable release system also includes a lockout mechanism configured to selectively impede shifting of the cable arrangement in response to the actuation force. Such selective impeding of the shifting of the cable arrangement is thereby configured to prevent actuation of the latch mechanism. A vehicle may employ the cable release system configured to actuate a latch mechanism to thereby unlatch a panel from the vehicle body.

First claim

What is claimed is:

1. A vehicle comprising:
a vehicle body defining a compartment;
a panel configured to cover the compartment;
a latch mechanism configured to selectively fasten the panel to the vehicle body such that the panel maintains closure of the compartment; and
a cable release system configured to actuate the latch mechanism to unlatch the panel from the vehicle body, including:
a cable arrangement configured to shift in response to an actuation force and thereby actuate the latch mechanism; and
a lockout mechanism configured to selectively impede shifting of the cable arrangement in response to the actuation force and thereby prevent actuation of the latch mechanism;

wherein the lockout mechanism includes:
a housing configured to mount therein a shiftable mounting block;
a pivotable stop lever; and
a cam lever configured to maintain the stop lever from pivoting into contact with the mounting block; and

wherein the cable arrangement includes:
a first cable having a first end connected to the latch mechanism and a second end extending into the housing and connected to the mounting block; and
at least one second cable having a first end configured to accept the actuation force and a second end extending into the housing and connected to the mounting block.

2. The vehicle of claim 1 , wherein the at least one second cable includes two cables connected to the mounting block.

3. The vehicle of claim 1 , wherein the housing includes a guide feature configured to guide a shift of the mounting block relative to the housing.

4. The vehicle of claim 1 , wherein the lockout mechanism additionally includes a bias spring configured to urge the stop lever to pivot into contact with the mounting block to thereby impede the shift of the mounting block and the shifting of the cable arrangement relative to the housing.

5. The vehicle of claim 4 , wherein the bias spring operates between the housing and the stop lever.

6. The vehicle of claim 5 , wherein each of the housing and the stop lever includes a respective locating feature configured to position and preload the bias spring within the housing.

7. The vehicle of claim 4 , wherein the stop lever includes a stop lever first end, a stop lever second end, and a pivot arranged between the stop lever first end and the stop lever second end, and wherein the bias spring acts on the stop lever first end, and the cam lever acts on the stop lever second end.

8. The vehicle of claim 1 , wherein the lockout mechanism additionally includes an electric actuator configured to actuate the cam lever and thereby permit the stop lever to pivot into contact with the mounting block.

9. The vehicle of claim 1 , wherein the housing includes a stop feature defining a limit position and travel of the cam lever.

10. A cable release system configured to actuate a latch mechanism, the cable release system comprising:
a cable arrangement configured to shift in response to an actuation force and thereby actuate the latch mechanism; and
a lockout mechanism configured to selectively impede shifting of the cable arrangement in response to the actuation force and thereby prevent actuation of the latch mechanism;
wherein the lockout mechanism includes:
a housing configured to mount therein a shiftable mounting block;
a pivotable stop lever; and
a cam lever configured to maintain the stop lever from pivoting into contact with the mounting block; and

wherein the cable arrangement includes:
a first cable having a first end connected to the latch mechanism and a second end extending into the housing and connected to the mounting block; and
at least one second cable having a first end configured to accept the actuation force and a second end extending into the housing and connected to the mounting block.

11. The cable release system of claim 10 , wherein the at least one second cable includes two cables connected to the mounting block.

12. The cable release system of claim 10 , wherein the housing includes a guide feature configured to guide a shift of the mounting block relative to the housing.

13. The cable release system of claim 10 , wherein the lockout mechanism additionally includes a bias spring configured to urge the stop lever to pivot into contact with the mounting block to thereby impede the shift of the mounting block and the shifting of the cable arrangement relative to the housing.

14. The cable release system of claim 13 , wherein the bias spring operates between the housing and the stop lever.

15. The cable release system of claim 14 , wherein each of the housing and the stop lever includes a respective locating feature configured to position and preload the bias spring within the housing.

16. The cable release system of claim 13 , wherein the stop lever includes a stop lever first end, a stop lever second end, and a pivot arranged between the stop lever first end and the stop lever second end, and wherein the bias spring acts on the stop lever first end, and the cam lever acts on the stop lever second end.

17. The cable release system of claim 10 , wherein the lockout mechanism additionally includes an electric actuator configured to actuate the cam lever and thereby permit the stop lever to pivot into contact with the mounting block.

18. The cable release system of claim 10 , wherein the housing includes a stop feature defining a limit position and travel of the cam lever.
