Abstract

A releasably mounted seat for a van-type vehicle is provided which in an embodiment includes a rear leg biased to latch to a floor of a vehicle, a seat bun frame joined to the rear leg providing a seating surface, a backing plate pivotally mounted with respect to the bun frame and selectively adjustable with respect to the bun frame means, a seat back pivotally mounted with respect to the backing frame and foldable between a first position generally extending with the backing plate and a second position folded forward generally adjacent the bun frame, and a single handle providing control to selectively position the seat back in the first and second positions and the handle providing control to selectively adjust the position of the backing plate with respect to the bun frame, and the handle providing control over the engagement of the latch of the rear leg with the vehicle floor.

Claims

1. A releasably mounted seat for a vehicle comprising:

at least one leg latched to a floor of a vehicle, the leg having a latch mechanism biased for engagement with the vehicle floor;

a seat bun frame joined to the leg providing a contact seating surface;

a backing plate pivotally mounted with respect to the bun frame;

a first adjuster mechanism to selectively adjust the position of the backing plate with respect to the bun frame;

a seat back pivotally mounted with respect to the backing frame;

a second adjuster mechanism to selectively position the seat back in a first position generally aligned and extending with the backing plate and a second position wherein the seat back is angled with respect to the backing plate and is folded forward generally adjacent the bun frame; and

a single handle providing control over the first adjuster mechanism to selectively adjust the position of the backing plate with respect to the bun frame and independent control over the second adjuster mechanism to selectively position the seat back in the first and second positions with respect to the backing plate, and the handle providing independent control over the engagement of the latch mechanism of the leg with the vehicle floor.

2. A vehicle seat as described in claim 1 wherein the leg latch mechanism cannot release from the vehicle floor until the seat back is folded forwardly in the second position.

3. A vehicle seat as described in claim 1 wherein the handle is pulled in a first direction a first amount to selectively adjust the position of the backing plate with respect to the bun frame and a second additional amount in the first direction to position the seat back from the first position to the second position and wherein the handle is moved in a second direction opposite the first direction to release the leg latch mechanism from the vehicle floor.

4. A vehicle seat as described in claim 3 wherein the first direction is generally upwardly and the second direction is generally downwardly.

5. A method of providing a releasably mounted seat for a vehicle comprising:

attaching a latch to a seat leg;

biasing the latch of the leg for engagement with a floor of the vehicle;

joining to the seat leg a seat bun frame providing a seating surface;

pivotally mounting with respect to the seat bun frame a backing plate;

selectively adjusting the position of the backing plate with respect to the bun frame by moving a handle in a first direction;

pivotally mounting with respect to the backing plate a seat back;

selectively positioning the seat back in a first position extending generally aligned with the backing plate to a second position angled with the backing plate and folded forwardly generally adjacent the bun frame by moving the handle a second additional amount in the first direction; and

releasing the latch of the leg from the vehicle floor by moving the handle in a second direction opposite the first direction.
