Abstract
A height-adjustable office chair having an incline-adjustable seat and back includes a bearing device to which is connected a length-adjustable seat pneumatic spring connected by an articulated joint to the seat structure, a length-adjustable back-rest pneumatic spring connected to the back by an articulated joint, and a height-adjustable pneumatic spring. The actuating rods of all three of these pneumatic springs are in the bearing device and are controlled by an actuating lever movable both horizontally and vertically. Vertical movement of the actuating lever controls the height-adjustable pneumatic spring. Horizontal movement of the actuating lever serves to control one of two intermediate levers which are respectively arrestable and lockable by a detent lever located above the height-adjustable pneumatic spring.
