Patent number: 11072372Abstract: A front side member includes, at a front portion, a front section in which an upper flange joint protrudes outward in a lateral direction of the vehicle. A reinforcing plate is overlapped with and welded to a laterally-outward side surface of the front section. The reinforcing plate includes a flange that is overlapped with and welded to the upper flange joint of the front side member. A rear end of the reinforcing plate extends to the same position as a rear end of the front section or further rearward. The reinforcing plate reduces deformation of the front section and the upper flange joint, inhibiting collapse of the closed cross sectional structure of the front side member.Type: GrantFiled: September 3, 2019Date of Patent: July 27, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koichi Enoki, Junichi Abe

Patent number: 9248766Abstract: A headrest stay includes a pair of first stay-composing parts extending in top and bottom directions of a seat back while supported by the seat back, the first stay-composing parts being arranged in different positions in a direction of vehicle width; and a second stay-composing part connecting specific parts of the first stay-composing parts in the direction of the vehicle width, the specific parts extending straight in the top and bottom directions of the seat back. The specific parts face a head of an occupant seated on the seat. A portion of the second stay-composing part, which portion is between the one specific part and the other specific part in the direction of the vehicle width, is not located further forward than the specific parts, and at least part of the portion is located further rearward than the specific parts.Type: GrantFiled: October 29, 2009Date of Patent: February 2, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koichi Enoki, Masahide Sawada

Patent number: 9174557Abstract: An S-spring 14 is provided in a state of tension between a pair of seat back frames 10 constituting a vehicle seat 1. A support section 16a of a bracket 16 fixed to the seat back frame 10 supports a part of an end of the S-spring 14 from behind. The support section 16a is formed with a length equal to or greater than one pitch of the S-spring 14 in a no-load state and discontinuously supports center portions ? of the S-spring 14. When a load equal to or greater than a predetermined level acts on the S-spring 14, the S-spring 14 is stretched to cause the center portions ? to be dislocated from the support sections 16a, and as a result, the length of a deflectable portion of the S-spring 14 is changed.Type: GrantFiled: March 1, 2011Date of Patent: November 3, 2015Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koichi Enoki, Masahide Sawada
