Tailgate open position adjustment system

1. A system for adjusting a position of a tailgate of a vehicle, the system comprising:

a cable connecting the tailgate to a spool, the spool configured to turn in a first direction to wind the cable around the spool, and turn in a second direction to unwind the cable from the spool;

a cable release located between the spool and the tailgate, the cable passing through the cable release, the cable release configured to be in an engaged state or an unengaged state, the cable release, when in the unengaged state, allowing the cable to move through the cable release when the spool turns in the first direction to wind the cable around the spool, and preventing movement of the cable through the cable release when force is applied to the cable from the tailgate, and the cable release, when in the engaged state, allowing the cable to move through the cable release when the spool turns in the second direction to unwind the cable around the spool; and

a button coupled to the cable release and configured to toggle the cable release between the engaged state and the unengaged state when the button is pressed.

2. The system of claim 1 , wherein the spool is a spring-loaded spool configured to automatically turn in the first direction to wind the cable around the spool, and

wherein the button is a single button configured to toggle the cable release between the engaged state and the unengaged state.

3. The system of claim 1 , wherein the spool is a motorized spool configured to turn in the first direction or the second direction, and

wherein the button includes a first button and a second button, pressing of the first button causing the spool to turn in the first direction, and pressing of the second button causing the cable release to be in the engaged state and causing the spool to turn in the second direction.

4. The system of claim 3 , wherein ceasing pressing of the second button causes the cable release to be in the unengaged state.

5. The system of claim 1 , wherein the cable release includes a first end proximal to the tailgate, a second end proximal to the spool, a housing, a plunger, and a spring axially located along a central axis and surrounding the cable,

wherein the housing includes a first opening proximal to the first end and a second opening proximal to the second end, and defines a cavity,

wherein the plunger is partially located within the cavity, extends out of the first opening of the housing, and is configured to move along the central axis and prevent movement of the cable when the plunger is moved toward the first end of the cable release, and allow movement of the cable when the plunger is moved toward the second end of the cable release,

wherein the spring is located within the cavity and connected to the plunger, and configured to urge the plunger along the central axis, toward the first end of the cable release,

wherein the cable release is moved from the unengaged state to the engaged state when a force is applied to the plunger toward the second end of the cable release in a direction opposing a force of the spring, and

wherein the cable release is moved from the engaged state to the unengaged state by the spring when the force applied to the plunger is removed.

6. The system of claim 5 , wherein the cavity defined by the housing has a narrower interior shape proximal to the first opening than the second opening, and

wherein the narrower interior shape causes the plunger to prevent movement of the cable when the plunger is moved toward the first end of the cable release.

7. The system of claim 5 , further comprising an actuator coupled to the button and the plunger of the cable release, and configured to apply or remove the force toward the second end of the cable release in the direction opposing the force of the spring.

8. The system of claim 1 , wherein the spool and the cable are located between an inner liner of the vehicle and a body outer panel of the vehicle and protected from cargo of the vehicle.

9. The system of claim 8 , wherein the button is located on the inner liner of the vehicle or the body outer panel of the vehicle.

10. The system of claim 1 , wherein the button is located on the tailgate.

11. A vehicle with an adjustable tailgate, the vehicle comprising:

a cable connecting the tailgate to a spool, the spool configured to turn in a first direction to wind the cable around the spool, and turn in a second direction to unwind the cable from the spool;

a cable release located between the spool and the tailgate, the cable passing through the cable release, the cable release configured to be in an engaged state or an unengaged state, the cable release, when in the unengaged state, allowing the cable to move through the cable release when the spool turns in the first direction to wind the cable around the spool, and preventing movement of the cable through the cable release when force is applied to the cable from the tailgate, and the cable release, when in the engaged state, allowing the cable to move through the cable release when the spool turns in the second direction to unwind the cable around the spool; and

a button coupled to the cable release and configured to toggle the cable release between the engaged state and the unengaged state when the button is pressed.

12. The vehicle of claim 11 , wherein the spool is a spring-loaded spool configured to automatically turn in the first direction to wind the cable around the spool, and

wherein the button is a single button configured to toggle the cable release between the engaged state and the unengaged state.

13. The vehicle of claim 11 , wherein the spool is a motorized spool configured to turn in the first direction or the second direction, and

wherein the button includes a first button and a second button, pressing of the first button causing the spool to turn in the first direction, and pressing of the second button causing the cable release to be in the engaged state and causing the spool to turn in the second direction.

14. The vehicle of claim 13 , wherein ceasing pressing of the second button causes the cable release to be in the unengaged state.

15. The vehicle of claim 11 , wherein the cable release includes a first end proximal to the tailgate, a second end proximal to the spool, a housing, a plunger, and a spring axially located along a central axis and surrounding the cable,

wherein the housing includes a first opening proximal to the first end and a second opening proximal to the second end, and defines a cavity,

wherein the plunger is partially located within the cavity, extends out of the first opening of the housing, and is configured to move along the central axis and prevent movement of the cable when the plunger is moved toward the first end of the cable release, and allow movement of the cable when the plunger is moved toward the second end of the cable release,

wherein the spring is located within the cavity and connected to the plunger, and configured to urge the plunger along the central axis, toward the first end of the cable release,

wherein the cable release is moved from the unengaged state to the engaged state when a force is applied to the plunger toward the second end of the cable release in a direction opposing a force of the spring, and

wherein the cable release is moved from the engaged state to the unengaged state by the spring when the force applied to the plunger is removed.

16. The vehicle of claim 15 , wherein the cavity defined by the housing has a narrower interior shape proximal to the first opening than the second opening, and

wherein the narrower interior shape causes the plunger to prevent movement of the cable when the plunger is moved toward the first end of the cable release.

17. The vehicle of claim 15 , further comprising an actuator coupled to the button and the plunger of the cable release, and configured to apply or remove the force toward the second end of the cable release in the direction opposing the force of the spring.

18. The vehicle of claim 11 , wherein the spool and the cable are located between an inner liner of the vehicle and a body outer panel of the vehicle and protected from cargo of the vehicle.

19. The vehicle of claim 18 , wherein the button is located on the inner liner of the vehicle or the body outer panel of the vehicle.

20. The vehicle of claim 11 , wherein the button is located on the tailgate.
