Patent ID: 7108324

Claim:
A pneumatic seat adjuster for moving a vehicle seat relative to a floor of the vehicle, said seat adjuster comprising: a body having a bore formed therein, the body adapted to be connected to one of a floor and a vehicle seat; a piston slidably disposed in said bore, said piston and said body defining first and second chambers, the piston adapted to be connected to the other one of the floor and the vehicle seat; a source of pressurized gas; a valve for selectively supplying pressurized gas from said source into said first and second chambers for altering a pressure differential between said first and second chambers to cause movement of said piston relative to said body; and a mechanical locking mechanism for preventing the movement of said body relative to said piston; wherein said valve selectively supplies pressurized gas from said source into said first and second chambers, and wherein said valve selectively vents gas from said first and second chambers for altering the pressure differential between said first and second chambers.
