Patent number: 10160069Abstract: A headrest stay is manufactured with a metal round pipe having a predetermined length and a predetermined thickness by performing a boring process on the metal round pipe by a cutting length of 5 mm or more from each of both distal ends of the metal round pipe to form a thin-walled portion that is thinner than the predetermined thickness; forming each of the distal ends of the metal round pipe into an curved chamfered shape having a radius of 5 mm or more by inserting each of the distal ends of the metal round pipe into a cylindrical hole; and bending the metal round pipe to have a shape of the headrest stay.Type: GrantFiled: March 9, 2016Date of Patent: December 25, 2018Assignees: TOYOTA BOSHOKU KABUSHIKI KAISHA, TOKAI CHEMICAL INDUSTRIES, LTD.Inventors: Hiroyuki Nasu, Akihide Ozaki, Koki Uemura

Patent number: 10150394Abstract: A headrest includes a stay, a headrest body, and a dynamic damper attached to the stay. The dynamic damper includes: an attachment member having an attachment portion attached to the stay and an opening having no bottom; an elastic member fixed along its entire perimeter by an edge of the opening and placed in the opening; and a weight embedded in the elastic member and placed in the opening. The attachment member includes a front-side divided body and a back-side divided body. The elastic member is sandwiched between the front-side divided body and the back-side divided body, whereby the elastic member is fixed along its entire perimeter by the edge.Type: GrantFiled: June 16, 2016Date of Patent: December 11, 2018Assignees: TOKAI CHEMICAL INDUSTRIES, LTD., TOYOTA BOSHOKU KABUSHIKI KAISHAInventors: Seiji Kobayashi, Hiroyuki Nasu

Patent number: 9663006Abstract: A vehicle seat provided in a vehicle includes a headrest with a pad in which an insert member is provided at a portion at which a head of an occupant is received. The insert member has rigidity that is higher than rigidity of the pad. When a rear-side collision occurs in the vehicle in a state in which the head of the occupant is away from the headrest and an inertia force applied to the occupant, the insert member allows the head of the occupant to sink into the headrest after the head of the occupant comes in contact with the headrest.Type: GrantFiled: April 23, 2015Date of Patent: May 30, 2017Assignees: TOYOTA BOSHOKU KABUSHIKI KAISHA, TOKAI CHEMICAL INDUSTRIES, LTD.Inventors: Hiroyuki Nasu, Koki Uemura

Publication number: 20170066352Abstract: A vehicle seat includes a seatback; a headrest that has a stay; and a headrest support that is arranged on an upper portion of the seatback so as to extend in a vertical direction, and that supports the stay in a manner that allows the stay to move in the vertical direction with an outer surface of the stay in sliding contact with a surface of an inner cylinder portion of the headrest support. The surface of the inner cylinder portion is covered by a resin coating that has a lower coefficient of friction with respect to the outer surface of the stay than material of which the headrest support is made.Type: ApplicationFiled: August 31, 2016Publication date: March 9, 2017Applicant: TOYOTA BOSHOKU KABUSHIKI KAISHAInventor: Hiroyuki NASU
