Abstract
A seat support mechanism for a tiltable chair having a rear tilt torque mechanism including interconnected torsion bars which are adjustable to vary the resilient restraining force which opposes rearward tilt of the seat when occupied, a detent mechanism which provides additional detent and stability to maintain the seat in its normal upright position and add to the resistance of the torque mechanism, and an adjustment mechanism for adjusting said detent mechanism for front tilt.
