<p>A tilting mechanism for a chair comprises two parts (15, 17), for connection to the chair seat (12) and chair back (13, 14) respectively, pivotally connected together for relative pivotal movement about a horizontal pivot (18), the parts being connected together by a pair of links (23, 24) pivotally connected to one of the parts (17) and also pivotally connected to a member (26) pivotally mounted on the other part (15) and formed with an arcuate row of teeth or recesses (29). A releasable stop bar (30) is provided for engagement in a selectible one of the recesses (29) in the pivotable member to lock it in a required position, so as to determine the relative angular position of the two parts of the mechanism and thus the degree of tilt of the chair back.</p> |
