<p>The present invention relates to connector for backrest of a chair, enabling to fix a backrest on the frame and to elastically pivot the backrest forward and rearward. The connector comprises: a first connector of which one longitudinal end is inserted and fixed in top end of the frame; a second connector which is combined with the other end of the first connector and guides the detachable coupling of the backrest in the vertical direction; and an elastic element which is installed between the first and second connectors and elastically rotate the second connector forward and rearward. Accordingly, the backrest and the frame can simplify an assembly process in accordance with a mutual detachable combination structure, and torsional deformation of the elastic element can improve reliability of a product since elasticity is able to minimize a reduction phenomenon compared to a coil spring.</p> |
