Latch rear seat back operation
View Patent ↗A vehicle seat for temporarily enlarging trunkspace includes a seat back and a seat bottom. The seat back is positionable in an upright position and a folded position. The seat back at least partially defines a portion of a vehicle storage compartment. In the folded position, the storage compartment is larger and able to hold more items than when the seat back is in the upright position. The vehicle seat is operable by a user with a single hand.
1. A vehicle seat operable to be folded by a user with a single hand, the seat back comprising:
a seat bottom;
a seat back positionable in an upright position and a folded position;
a latching system operable to release the seat back so that the seat back is moveable to folded position, the latching system comprising:
a first handle;
a second handle; and
a cable actuation system in communication with the first and second handle, the cable actuation system including a cable and a cable sheath such that the cable is moveable within the cable sheath wherein operation of either the first handle or the second handle causes movement of the cable sheath thereby releasing the seat back so that the seat back may be moved to the folded position.
2. The vehicle seat of claim 1 wherein the cable actuation system includes a first lock actuator that has a first locked setting and a first release setting, the first lock setting holding the seat back in the upright position and a release setting that allows the seat back to be positioned in the folded position.
3. The vehicle seat of claim 2 wherein the cable actuation system further includes a second lock actuator that has a second locked setting and a second release setting, the second lock setting holding the seat back in the upright position and a release setting that allows the seat back to be positioned in the folded position.
4. The vehicle seat of claim 3 wherein the first lock actuator is set to the first release setting and the second lock actuator is set to the second release setting in order to allow positioning of the seat back to the folded position.
5. The vehicle seat of claim 4 wherein the cable actuation system includes a cable and a cable sheath such that the cable is moveable within the cable sheath.
6. The vehicle seat of claim 5 wherein the cable sheath has a first position held substantially rigid with respect to the first lock actuator and a second end held substantially rigid with respect to the second lock actuator.
7. The vehicle seat of claim 6 wherein the first handle is in communication with a first end of the cable and the second handle is in communication with a second end of the cable.
8. The vehicle seat of claim 7 wherein movement of the first handle or the second handle causes movement of the cable such that the cable sheath moves in a manner to cause positioning of first lock actuator in the first release setting and the second lock actuator in the second release setting thereby allowing positioning the seat back in the folded position.
9. The vehicle seat of claim 8 wherein the first lock actuator includes a first lock lever that is operable to pivot to a predetermined position when the cable is moved by either the first or second handle.
10. The vehicle seat of claim 7 wherein positioning in the first lock actuator in the first release setting and the second lock actuator in the second release setting occurs sequentially.
11. The vehicle seat of claim 1 wherein the seat back partially defines a vehicle storage compartment.
