Abstract
A collapsible seat for use in pickup trucks and the like which is totally enclosed in the collapsed position by a floor, sidewalls, endwalls and a top. The top is pivotally connected to one of the sidewalls. A backrest is attached to the underside of the top of the enclosure. The seat itself is vertically adjustable by pneumatic means and consists of two pneumatically interconnected pairs of telescoping legs, one pair at either end of the seat. Each pair of legs is also interconnected at the top by an armrest. When pressurized air is introduced into each pair of telescoping legs an airtight chamber within said telescoping legs is caused to expand thereby forcing the seat upwardly in a vertical direction. The seat may be collapsed by removing the air from the airtight chambers within the telescoping legs and folding the backrest downwardly over the seat.

2. A seat as claimed in claim 1 wherein a backrest is attached to the underside of the enclosure cover.
-
3. A seat as claimed in claim 2 wherein the tops of each pair of telescoping legs are interconnected by an armrest.
-
4. A seat as claimed in claim 3 wherein the enclosure cover and endwalls contain interengaging means which limit movement of the enclosure cover from a closed to a substantially upright position.
-
5. A seat as claimed in claim 4 wherein the interengaging means consist of two solid braces attached to the enclosure cover near the backward corners and which, when the enclosure cover is in a closed position, extend inwardly and backwardly toward the backwall and then outwardly through arcuate openings in each endwall such that when the enclosure cover is raised the brace will move forwardly through the arcuate opening and be restrained against the forward end of the arcuate opening when the cover is in an upright position.
-
6. A seat as claimed in claim 4 wherein each telescoping leg consists of a piston portion and a cylinder portion, the bottom of the piston portion being attached to the floor of the enclosure and the top of the piston portion containing a flexible disc, said piston being slidably engaged in the cylinder portion such that the flexible disc engages the inside wall of the cylinder in an airtight relationship creating an airtight cylinder compartment between the flexible disc and the top of the cylinder.
-
7. A seat as claimed in claim 6 wherein the interconnecting portion between the airtight cylinder compartments is housed within the armrest attached to the top of the cylinder portion of each pair of telescoping legs.
-
8. A seat as claimed in claim 6 wherein the flat surface area of the seat in the collapsed position forms a cargo carrying area.
-
9. A seat as claimed in claim 8 wherein the vehicle bed contains sidewalls which are higher than the sidewalls of the seat enclosure.
