Publication number: 20180043939Abstract: A vehicle front pillar includes: a front pillar outer member, and a roof inner reinforcement and a front pillar inner member, the front pillar having a length oriented in the vehicle longitudinal direction and closed cross sections over the entire length. The outer member and the roof inner reinforcement each include an inward flange directed laterally inward. The inner member includes an outward flange directed laterally outward. The outer member inward flange is overlapped and joined to the inner member outward flange, forming a closed cross section of the front pillar. The roof inner reinforcement inward flange is overlapped and joined to the outer member inward flange. The inner member includes a first ridge projecting toward the vehicle inside, defining a first groove open toward the vehicle outside, or the outer member includes a second ridge projecting toward the vehicle outside, defining a second groove open toward the vehicle inside.Type: ApplicationFiled: December 16, 2015Publication date: February 15, 2018Applicant: TOYODA IRON WORKS CO., LTD.Inventors: Kazuaki KITAGUCHI, Akiyoshi KATO

Publication number: 20170029033Abstract: A tubular reinforcement for a vehicle including a tubular portion having a sheet metal rolled to have closed edges, and an integral attachment portion formed from the same sheet metal, the attachment portion extending longitudinally from a tubular portion end and having a planar attachment base. The attachment base is raised to bring forward the contact surface, forming a peripheral wall. The tubular reinforcement is disposed in the vehicle so that an attachment base contact surface closely contacts a mounting location in the vehicle. The attachment portion lateral edges have lateral flanges on the peripheral wall opposite sides extending along with the peripheral wall toward the contact surface plane. The peripheral wall and the lateral flanges form turnback portions on both sides of the attachment base, each turnback portions defining a concavity recessed from the contact surface and having a U- or J-shaped section perpendicular to a tubular portion centerline.Type: ApplicationFiled: April 1, 2014Publication date: February 2, 2017Applicant: TOYODA IRON WORKS CO., LTD.Inventors: Kazuaki KITAGUCHI, Akira OBAYASHI, Makoto NAKANISHI, Takeshi NAKAYAMA

Patent number: 9550477Abstract: A vehicle pedal device includes a main bracket with a pair of side plates supporting a pedal and attached to a dash panel, and a sub-bracket coupling a main bracket rear end and reinforcement. Where both ends of a clinching pin inserted through coupling holes formed in side plate rear ends are inserted through insertion holes of sub-bracket side plate portions, the both ends are axially clinchingly compressed, whereby the rear ends are clinchingly attached to the portions to be overlapped, inner peripheral edges of the coupling and insertion holes having a non-circular shape, distances from their centers circumferentially varying, the portions being extended outward to be separated further away from the side plates toward the panel, and the insertion holes formed in the portions having an elongated hole shape whose length allows the both ends protruding from the side plates to pass therethrough where the portions are extended outward.Type: GrantFiled: April 1, 2013Date of Patent: January 24, 2017Assignee: TOYODA IRON WORKS CO., LTD.Inventor: Kazuaki Kitaguchi
