Chair with tilt limiter
First Claim
1. A chair having a control mechanism configured to limit an angle of tilt of a chair back rest assembly relative to a chair seat, said chair comprising:
- a bracket member configured to be supported on a vertical column of a chair base;
a rotational member supported for rotation on an end of said bracket member, said rotational member being attached to the chair back rest;
a generally elongate stop member secured to said rotational member at a position extending inwardly of said end of said bracket member; and
a slide member slidable along a longitudinal axis of said bracket member and having a first generally U-shaped end provided with two mutually aligned and spaced downward directed inclined edges for engagement with said stop member;
said stop member having a free distal end configured to engage said inclined edges of said slide member and limit rotation of said rotational member and the chair back rest;
wherein said rotational member is rotatable through one of a plurality of ranges of degrees of rotation as determined by a specific position of said slide member along said longitudinal axis.

Abstract
A chair has a control mechanism configured to limit the angle of tilt of the chair back rest relative to the seat. The control mechanism includes a bracket member configured to be supported on a vertical column of a chair base. A rotational member attachable to the chair back rest is supported for rotation on an end of the bracket member. A generally elongated stop member is secured to the tubular member at a position extending inwardly of the end of the bracket member. A slide member extends along the longitudinal axis of the bracket member and has one end provided with at least one downwardly directed inclined edge. The stop member has a free distal end configured to engage the inclined edge and limit rotation of the tubular member. By this arrangement, the chair user can adjust the degree of rearward tilt of the back rest by selected movement of the slide member longitudinally of the bracket member.
