Stowable vehicle seat apparatus and method

1. A vehicular seat moveable between a deployed position and a stowed position, the seat comprising:

a mount adapted to be coupled to an interior surface of a vehicle such that the mount is stationary with respect to the interior surface;

a seat base coupled to the mount and moveable with respect to the mount, the mount extending substantially the distance between the interior surface of the vehicle and the seat base;

a variable length strut coupled to the mount, the variable length strut having a first strut portion coupled to the mount and having a second strut portion coupled to the first strut portion and the seat base, the first strut portion movable with respect to the second strut portion;

a lock having a locked state in which the first and second strut portions are not movable with respect to one another to substantially prevent movement of the seat base with respect to the mount, and an unlocked state in which the first and second strut portions are movable with respect to one another to allow movement of the seat base with respect to the mount;

a seat back moveable between an upright position relative to the seat base and a folded position relative to the seat base;

a latch selectively engaging the seat back to substantially prevent movement between the upright and folded positions; and

a user-manipulatable control coupled to the lock and operable to change the state of the lock, and coupled to the latch and operable to disengage the latch from the seat back, thereby affording movement of the seat base with respect to the mount and movement of the seat back relative to the seat base,

wherein the lock is coupled to the latch by a cable, the latch rotating in response to operation of the user-manipulatable control to disengage the seat back and afford movement of the seat back relative to the seat base, and wherein rotation of the latch for disengagement from the seat back pulls on the cable to unlock the lock.

2. The vehicular seat as claimed in claim 1 , wherein the variable length strut is one of a pneumatic cylinder and a hydraulic cylinder.

3. The vehicular seat as claimed in claim 1 , wherein the variable length strut is pivotably coupled to the mount and to the seat base.

4. A vehicular seat, comprising:

a seat base rotatable about a first axis between a deployed position in which the seat base is substantially horizontal and positioned to support a seated user, and a stowed position in which the seat base is rotated away from the deployed position;

a seat back rotatable about a second axis, wherein the second axis is non-parallel with respect to the first axis;

a strut coupled to the seat base and another portion of the seat, and variable to different lengths corresponding to different rotational positions of the seat base;

a lock coupled to the strut, the lock having a locked state in which the strut is secured against change in length in any of the different rotational positions of the seat base, thereby preventing rotation of the seat base, and an unlocked state in which the length of the strut can be changed for rotation of the seat base;

a user-manipulatable control, wherein the seat back has a first state in which the seat back is rotatable with respect to the seat base and a second state in which the seat back is secured against rotation with respect to the seat base, and wherein the user-manipulatable control is operable to release the seat back from the second state to the first state; and

a latch coupled to the user-manipulatable control and movable by the user-manipulatable control to selectively secure the seat back against rotation relative to the seat base,

wherein the user-manipulatable control is coupled to the strut by way of the latch, and wherein movement of the latch by the user-manipulatable control to afford rotation of the seat back relative to the seat base operates to unlock the lock.

5. The vehicular seat as claimed in claim 4 , farther comprising a user-manipulatable control coupled to the strut and operable to change the state of the lock.

6. The vehicular seat as claimed in claim 5 , wherein the user-manipulatable control is coupled to the strut by a cable.

7. The vehicular seat as claimed in claim 4 , wherein the strut is one of a pneumatic cylinder and a hydraulic cylinder.

8. The vehicular seat as claimed in claim 4 , wherein the strut is pivotably coupled to the seat base.

9. A method of changing the position of a vehicle seat with respect to a vehicle, the seat including a seat base and a seat back pivotable with respect to the seat base between a folded position and an upright position, the method comprising:

operating a user-manipulatable control;

unlatching a seat back latch in response to operation of the user-manipulatable control to allow movement of the seat back from the upright position toward the folded position;

unlocking a seat base lock in response to unlatching the seat back latch to allow movement of the seat base from a lowered position toward a raised position;

rotating the seat base about a first axis;

changing the length of a strut by rotating the seat base, wherein the strut is coupled to the seat base and secured against a change in length when the seat base lock is in a locked state;

rotating the seat back toward the folded position about a second axis, wherein the second axis is non-parallel with respect to the first axis.

10. The method as claimed in claim 9 , wherein operating the user-manipulatable control includes rotating a shaft to unlatch the seat back latch, and wherein unlatching the seat back latch includes rotating the latch.

11. The method as claimed in claim 9 , wherein rotating the seat base further comprises pivoting the strut with respect to the seat base.

12. The method as claimed in claim 10 , wherein the seat base lock is coupled to the seat back latch by a cable, and wherein rotating the shaft to unlatch the seat back latch includes pulling on the cable to unlock the seat base lock.
