Backrest and foot rest linking mechanism

Abstract

The invention discloses a backrest and foot rest linking mechanism. At the present, no chairs that integrate a backrest chair and a deck chair and are convenient for letting feet take a rest are provided. A first rocker consists of a chair back supporting rod and a rocking lever which are welded together; the rocking lever is hinged to the bottom of a chair seat through a pin shaft; a resetting torsional spring sleeves the pin shaft; one end of a positioning rod is hinged to the middle part of the chair back supporting rod; two positioning slots are formed in the positioning rod; the bottom end of the chair back supporting rod is hinged to one end of a first connection rod; the other end of the first connection rod is hinged to one end of a second rocker; the other end of the second rocker is hinged to the bottom of the chair seat at a point D; a third rocker is fixedly connected with the second rocker; one end of the third rocker is hinged to the bottom of the chair seat at a point D; the other end of the third rocker is hinged to one end of a second connection rod; the other end of the second connection rod is hinged to one end of a fourth rocker; the other end of the fourth rocker is hinged to the bottom of the chair seat; and the second connection rod is fixedly connected with a triangular block. By the adoption of the backrest and foot rest linking mechanism, the backrest chair can be either used for work in an office or used as a lying chair for taking a rest.
