A rear support frame has its lower and rearward end in engagement with the floor while its upper and forward end is pivotally secured to the rearward side of the chair. The rear support frame is forcibly pivotally rotated relative to the chair in order to selectively vary the extent to which the chair reclines rearwardly.As the pivoting action takes place, the main part of the chair turns upon its rocker-like members. The lower and rearward end of the rear support frame slides or rolls horizontally along the floor surface. The weight of the occupant of the chair is at all times divided between two forward support points which are provided by the rocker-like members, and a rear support point which is provided by the rear support frame. | |
