Abstract
An adjustable armrest for use with an operator's seat on a vehicle includes a pair of pins which project laterally from a side of the seat. A generally rectangular frame has an open side which faces the seat. A pair of gear wheels mounted for rotation on the frame about its central axis. Each gear wheel has another bore which is offset from the central bore and which receives one of the pins. A drive gear drives a belt which rotates the gear wheels to move the drive gears and frame with respect to the pins. A knob is slidably and non-rotatably coupled to an end of a sleeve which, in turn, is fixed to the drive gear. The knob is rotatably and non-slidably coupled to an end of a shaft which is slidable in the sleeve. The other end of the shaft is coupled to a locking pawl. As spring urges the knob, shaft and pawl to a locking position wherein the pawl engages the gear wheels cylinders to prevent their rotation. The knob is movable against the spring to disengage the pawl from the gear wheels.
