TILTING MECHANISM FOR A CHAIR

摘要

A tilting mechanism for a chair comprises two parts , for connection to the chair seat and chair back respectively, pivotally connected together for relative pivotal movement about a horizontal pivot , the parts being connected together by a pair of links pivotally connected to one of the parts and also pivotally connected to a member pivotally mounted on the other part and formed with an arcuate row of teeth or recesses . A releasable stop bar is provided for engagement in a selectible one of the recesses 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.
