Patent number: 9327627Abstract: An unlocking mechanism of inclinable headrest includes a push button having a connecting element and an internal frame having a cylindrical element defining a through-bore in which the push button is slidably accommodated. Provided within the internal frame is a slidable lever element having one end operatively connected with a lock gear for locking the headrest and another end having a connecting hole in which the connecting element of the push button is resiliently inserted and engaged. The slidable lever element is slidably supported by a guide element so that the connecting hole thereof is retained at a location corresponding to the through-bore of the cylindrical element. Hence, in assembly, simple insertion by a worker of the push button in the cylindrical element results in quick and precise connection of the push button's connecting element with the slidable lever element's connecting hole invisibly disposed in the headrest.Type: GrantFiled: January 29, 2013Date of Patent: May 3, 2016Assignee: TACHI-S CO., LTD.Inventors: Hideo Tobata, Takayuki Yoshiga, Yutaka Sodeno
