ABSTRACT:
A lockable gas cylinder in parallel with a mechanical spring controls the adjustment of tilt in a chair seat and back. A linkage mechanism permits tilting of the chair seat about a pivot located close to the forward edge of the seat and permits tilting of the back about a pivot which is located near the rear edge of the seat. The gas cylinder may be released to permit rocking of the chair against the force of the mechanical spring alone.
