Abstract:
A folding chair has a height adjustable seat whose height is controlled by a pneumatic cylinder having locking springs is seated inside each of the two tubular front legs of the chair. A trigger mechanism allows the user to release the locking aspect of the springs, adjusting the height of the seat before locking the spring length again. The chair is supported by a pair of cylindrical sleeves that move up and down the front legs and that are connected by a seat stop bar that maintains the seat in a position ready for use because it is contacted by the straight rear edge of a pair of gussets connected to the sides of the seat. The chair seat pivots upward into a storage position through a pair of hollow pins connected to fittings at the top of the pneumatic cylinders and that move up and down the front legs within an elongated slot cut into each front leg.
