Abstract

An adjustable seat for use in a passenger compartment of a vehicle. A seat cushion is slidably mounted for movement between an aft position and a fore position, and a seat back is connected to the seat cushion. A latch connected to the seat back, and a mounting member is connected to the vehicle that releasably engages the latch to limit fore-aft movement of the seat back with respect to the mounting member so that movement of the seat cushion from the aft position to the fore position moves the seat back from an upright position to a reclined position.

Claims

1. An adjustable seat for use in a passenger compartment or a vehicle, comprising:

a seat cushion that is slidably mounted for movement between an aft position and a fore position;

a seat back that is connected to the seat cushion;

a latch connected to the seat back; and

a mounting member adapted to be connected to a rear wall of the passenger compartment that releasably engages the latch to limit fore-aft movement of the seat back with respect to the rear wall of the passenger compartment so that movement of the seat cushion from the aft position to the fore position causes the seat back to move from an upright position to a reclined position, wherein the mounting member is an upright bar, and the latch is slidably related to the mounting member such that the latch slides downward along the mounting member as the seatback moves from the upright position to the reclined position.

2. The adjustable seat of claim 1, wherein the latch moves downward with respect to the mounting member as the seat cushion moves from the aft position to the fore position.

3. The adjustable seat of claim 1, wherein the seat cushion is pivotally mounted with respect to a floor of the passenger compartment for movement between a seating position and a stowed position.

4. The adjustable seat of claim 3, wherein the latch is engaged with the mounting member when the seat cushion is in the seating position and when the seat cushion is disposed in the stowed position.

5. The adjustable seat of claim 1, wherein the seat back is pivotally mounted to the seat cushion for movement between a seating position and a folded flat position.

6. The adjustable seat of claim 5, wherein the latch is engaged with the mounting member when the seat back is in the seating position and the latch is not engaged with the mounting member when the seat back is in the folded flat position.

7. The adjustable seat of claim 6, further comprising:

a release lever operatively connected to the latch for releasing engagement of the latch with respect to the mounting member.

8. The adjustable seat of claim 1, further comprising:

an adjustment lever to selectively restrain the seat cushion from moving between the aft position and the fore position.

22. The adjustable seat of claim 1, further comprising:

the mounting member having a curved portion, wherein the latch moves along the curved portion of the mounting member as the seat back moves from the upright position to the reclined position.

23. The adjustable seat of claim 1, wherein the latch is recessed with respect to a rear surface of the seat back.

9. An adjustable seat for use in a passenger compartment of a vehicle, comprising:

at least one support member adapted to be connected to a floor of the passenger compartment;

a sliding frame pivotally connected to the at least one support member;

a seat cushion that is slidably mounted to the sliding frame for movement between an aft position and a fore position;

a seat back that is pivotally connected to the seat cushion at a lower end of the seat back;

a latch connected to the seat back at an upper end of the seat back; and

a mounting member adapted to be connected to a rear wall of the passenger compartment that releasably engages the latch to limit fore-aft movement of the upper end of the seat back with respect to the rear wall of the passenger compartment so that movement of the seat cushion from the aft position to the fore position causes the seat back to pivot with respect to the seat cushion from an upright position to a reclined position, wherein the mounting member is an upright bar, and the latch is slidably related to the mounting member such that the latch slides downward along the mounting member as the seatback moves from the upright position to the reclined position.

10. The adjustable seat of claim 9, wherein the latch moves downward with respect to the mounting member as the seat cushion moves from the aft position to the fore position.

11. The adjustable seat of claim 9, wherein the seat cushion and the sliding frame are pivotally movable with respect to the at least one support member for movement between a seating position and a stowed position.

12. The adjustable seat of claim 11, wherein the latch is engaged with the mounting member when the seat cushion is in the seating position and when the seat cushion is in the stowed position.

13. The adjustable seat of claim 9, wherein the seat back is pivotally moveable with respect to the seat cushion between a seating position and a folded flat position.

14. The adjustable seat of claim 13, wherein the latch is engaged with the mounting member when the seat back is in the generally upright seating position and the latch is not engaged with the mounting member when the seat back is in the folded flat position.

15. The adjustable seat of claim 9, wherein the at least one support member spaces the sliding frame with respect to the floor of the passenger compartment.

16. The adjustable seat of claim 9, further comprising:

an adjustment lever to selectively restrain the seat cushion from moving between the aft position and the fore position.

17. An adjustable seat for use in a passenger compartment of a vehicle, comprising:

a pair of support members adapted to be connected to a floor of the passenger compartment;

a sliding frame pivotally connected to the pair of support members by a first pivot joint so that the pair of support members space the sliding frame from the floor of the passenger compartment, the sliding frame having a first pair of track members;

a seat cushion having a second pair of track members, the second pair of track members engaged with the first pair of track members of the sliding frame to slidably mount the seat cushion to the sliding frame for movement between an aft position and a fore position, the seat cushion and the sliding frame pivotally movable with respect to the pair of support members about the first pivot joint for movement between a seating position and a stowed position;

a seat back that is pivotally connected to the seat cushion by a second pivot joint at a lower end of the seat back for movement of the seat back between a seating position and a folded flat position;

a latch connected to the seat back at an upper end of the seat back; and

a mounting member adapted to be connected to a rear wall of the passenger compartment that releasably engages the latch to limit fore-aft movement of the upper end of the seat back with respect to the rear wall of the passenger compartment so that movement of the seat cushion from the aft position to the fore position causes the seat back to pivot with respect to the seat cushion from an upright position to a reclined position, wherein the mounting member is an upright bar, and the latch is slidably related to the mounting member such that the latch slides downward along the mounting member as the seatback moves from the upright position to the reclined position.

18. The adjustable seat of claim 17, wherein the latch moves downward with respect to the mounting member as the seat cushion moves from the aft position to the fore position.

19. The adjustable seat of claim 17, wherein the latch is engaged with the mounting member when the seat cushion is in the seating position or in the generally upright stowed position.

20. The adjustable seat of claim 17, wherein the latch is engaged with the mounting member when the seat back is in the seating position and the latch is not engaged with the mounting member when the seat back is in the folded flat position.

21. The adjustable seat of claim 17, further comprising:

an adjustment lever to selectively restrain the seat cushion from moving between the aft position and the fore position.
