An armrest adjustment mechanism supports an armrest unit with respect to a vehicle seat. The mechanism includes a plate fixed to the seat. The fixed plate has a pair of projecting pins and a plate slot extending between the pins. A frame is movably mounted adjacent to the plate and attached to the armrest unit. The frame has a bore extending therethrough and a pair of frame slots which slidably receive the pins. A bolt has a head which non-rotatably engages the plate and which is slidable in the plate slot. The bolt has a threaded shaft which extends through the bore in the plate. A knob is rotatably and threadably mounted on the end of the shaft. A hollow cylindrical bushing is mounted on the shaft between the knob and the frame. The knob can be rotated to clamp the frame with respect to the plate, or loosened to allow the frame to be moved with respect to the plate.
