Abstract
A height adjustment arrangement for a headrest or the like includes a spring in a rear recess of a backrest. A T-shaped trigger member is received in the recess for biasing against the spring. A plate is secured onto the recess, with the plate having a slit. A finger tab of the trigger member projects from the horizontal slit. Two upright tubes are formed either on sides of a J-bar or on a backside of the backrest. An, inverted U-shaped rod has a top attached to the headrest or the like and two groups of notches opposite the backrest. The trigger member is locked in two notches. In operation, the finger tab is pushed to compress the spring for disengaging the trigger member from the notches. The rod can be raised or lowered relative to the trigger member until a desired height is reached. Finally, the finger tab can be released to lock the trigger member in the other notches again.
