ABSTRACT:
A chair having height-adjustable arm assemblies respectively mounted adjacent opposite sides of a seat. Each arm assembly includes a horizontally elongate armrest connected to an upper end of an arm upright. The arm upright includes a vertically oriented support segment which has a guide bore defined therein. The armrest includes a vertically elongate slide tube and a horizontally elongate arm element connected to an upper end of the slide tube. A lower end of the slide tube is movably mounted within the guide bore. A lock arrangement functions to permit the slide tube to be positioned relative to the support segment at any one of a plurality of height positions. The lock arrangement includes a cartridge assembly that has a gear which is rotatably supported and carried by the slide tube. The gear has a plurality of gear teeth which engage with a series of vertically spaced notches defined within the support segment. A lock releasing mechanism functions to displace a lock member between a locking position and a releasing position. The lock releasing mechanism includes an actuator lever and an actuator rod. The actuator lever is supported on the arm element, and the actuator rod extends into the slide tube and mounts the lock member on the lower end thereof. The lock member has locking teeth which engage the gear when the lock member is positioned in the locking position.
