Publication number: 20240123880Abstract: A seat back panel includes a panel main body and a separate panel. The panel main body is disposed at a posterior portion of a seat back of a vehicle seat. The panel main body structures a portion of a main body portion of a seat back frame. An aperture is formed at a location of the panel main body that opposes a dorsal region of a seat occupant. The separate panel is attached to the main body portion and closes up the aperture. At a time of rear-end collision of the vehicle, the separate panel receives a load from the dorsal region of the seat occupant and relatively displaces toward the rear side of the seat back with respect to the panel main body.Type: ApplicationFiled: April 21, 2023Publication date: April 18, 2024Inventors: Takumi Arai, Takuma Oki, Yusuke Yadomaru, Masami Handa, Toshimitu Nishio

Patent number: 5509600Abstract: A method of hot pressure welding of hot steel stock, in which the ends of the steel stock are descaled mechanically and pressure joined under a reducing flame. Since re-oxidation after descaling is prevented and the feasible temperature for hot pressure joining is maintained by the reducing flame, the joining is accomplished firmly and strong joints are obtained.Type: GrantFiled: May 27, 1994Date of Patent: April 23, 1996Assignee: Sumitomo Metal Industries, Ltd.Inventors: Seiji Okada, Yutaka Suzuki, Kouichi Sakamoto, Hitoshi Teshigahara, Takao Taka, Yasuto Fukada, Masami Oki
