PUSH BUTTON ADJUSTER FOR CHAIR BACKREST ABSTRACT A low cost, highly convenient, and non-complicated push button adjuster for chair backrest eliminates bulky and un- sightly protruding levers, hand wheels and other external oper- ators. A simple push button normally flush with the rear face of a backrest is depressed to shift a connected locking pin out of a detent slot in a backrest support bar so that the backrest is released for height adjustment. The push button and locking pin are spring-biased to the active locking position.
