Abstract
Abstract The rocking component is pivotally mounted by the upstanding flexible steel rods on the wheel frame and is guided by means of pairs of guide wheels which roll on the upper horizontal curved rail bar of the wheel frame. The foot rest is adjustable relative to the floor level and is pivotal in two directions so as to be folded up into a vertical position and then pivoted backward into the chair frame.
