Publication number: 20150048635Abstract: A bumper reinforcement includes a tubular body including a front wall that serves as an impact surface and a rear wall on a vehicle body side, the tubular body extending in a vehicle width direction and having a hollow cross section; and a tow hook attachment structure for allowing a tow hook to be removably attached thereto. The tow hook attachment structure includes a pair of cylindrical protrusions respectively integrally formed with the front and rear walls of the tubular body by shaping parts of the walls, the cylindrical protrusions being disposed at predetermined positions on the front and rear walls in the vehicle width direction so as to face each other and so as to protrude inward into the hollow cross section, and at least one of the pair of protrusions includes a threaded portion for allowing a threaded portion of the tow hook to be screwed thereinto.Type: ApplicationFiled: July 15, 2014Publication date: February 19, 2015Applicant: Kabushiki Kaisha Kobe Seiko Sho (Kobe Steel, Ltd.)Inventors: Hideki ISHITOBI, Narikazu Hashimoto, Tsunetake Tsuyoshi

Publication number: 20140353990Abstract: An end of a stay material made of a tubular aluminum alloy extruded material is expanded by electromagnetic molding to form a flange for producing a bumper stay. The flange width is increased without cracking and a decrease in the thickness. A stay material having a circumferential wall undulating in a waveform pattern is used. A circumferential length L (one round length along waveform pattern) of the outer periphery wall along the circumferential direction of the stay material is longer than a circumferential length L0 of a simple cylindrical circumferential wall having the same outer diameter (circumscribed circle) (L>L0). L?L0 is an excessive line length. Since the circumferential wall has the excessive line length, when the end of the circumferential wall is expanded to form the flange, the flange having a large diameter can be formed.Type: ApplicationFiled: January 24, 2013Publication date: December 4, 2014Applicant: KABUSHIKI KAISHA KOBE SEIKO SHO (Kobe Steel, Ltd.)Inventors: Hideki Ishitobi, Hiroaki Hosoi, Keisuke Akasaki

Publication number: 20140015285Abstract: A vehicle hood panel is formed by bonding an outer panel and an inner panel to each other. Disposed along the outer peripheral edge of the inner panel is an outer peripheral portion to which a cushion member and hinges for attaching the hood panel to a vehicle are to be later fastened. Adhesive bonding surfaces which are to be bonded to the outer panel by mastic are disposed on the region surrounded by the outer peripheral portion, and a plurality of reinforcement beads are formed between the adhesive bonding surfaces. At least some of the adhesive bonding surfaces and/or reinforcement beads are bended so as to extend toward the hinges or the cushion member as seen in a plan view.Type: ApplicationFiled: April 2, 2012Publication date: January 16, 2014Applicant: KABUSHIKI KAISHA KOBE SEIKO SHO (Kobe Steel, Ltd.)Inventors: Hideki Ishitobi, Masatoshi Yoshida
