Publication number: 20230202356Abstract: A vehicle seat includes a first hinge rotatably supporting a left seatback framework and a second hinge rotatably supporting a center seatback framework. The first hinge includes a first base bracket and a first hinge bracket continuous to the first bracket, and the second hinge includes a second base bracket and a second hinge bracket continuous to the second base bracket. Each of the first hinge and the second hinge has a frame bracket coupled to the corresponding seatback framework and a shaft about which the hinge rotates. An urging member is wound on the shaft. A joining part joins a distal end of the first hinge bracket of the first hinge to a distal end of the second hinge bracket of the second hinge.Type: ApplicationFiled: June 23, 2021Publication date: June 29, 2023Applicant: DELTA KOGYO CO., LTD.Inventors: Atsushi ONJI, Yuki ARITA, Yuki SATO, Masato NARAKI

Publication number: 20220169159Abstract: Provided is a seat enabling reduction of a burden in skin assembling work and improvement of appearance quality of the seat. A seat includes linear members extending along a longitudinal direction of hanging portions of a skin and provided at the hanging portion, and elastically deformable tubular members provided inside grooves of a pad so as to extend along the groove. A slit is formed on an outer peripheral surface of the tubular member, the slit extending in a longitudinal direction of the tubular member, having a width narrower than an outer diameter of the linear member, and enabling the width to be expanded by elastic deformation of the tubular member.Type: ApplicationFiled: April 30, 2020Publication date: June 2, 2022Applicant: DELTA KOGYO CO., LTD.Inventors: Yuki ARITA, Kohei ISODA, Mizuki KATO, Atsushi ONJI

Patent number: 9738196Abstract: A base net for a back is formed from a three-dimensional stereoscopic knit, and has a configuration in which seams for bringing a pair of ground knitted fabrics thereof to close to each other in a thickness direction are partially provided, predetermined preliminary compression is applied in the thickness direction by the seams, and thereby residual stress is generated in a surface direction (stretching direction). Therefore, stiffness is partially increased by partial improvement in residual stress, and consequently a human body with extreme roughness is supported by nearly uniform pressure. Thus, in spite of a simple configuration in which the seams are provided in desired regions, posture supportiveness and body pressure dispersiveness can be improved. Further, by arbitrarily adjusting the formation positions of the seams, the pressure distribution is adjusted, thereby making it possible to easily control the vibration mode to desired setting, and easily improve vibration absorbency.Type: GrantFiled: November 23, 2012Date of Patent: August 22, 2017Assignee: Delta Tooling Co., Ltd.Inventors: Yumi Ogura, Etsunori Fujita, Seiji Kawasaki, Shogo Inoue, Yuki Arita, Eiji Sugimoto

Patent number: 9527228Abstract: Even when a mixture resin of virgin resin and recovered resin material is used as a resin material for molding, a stable, high-quality foam-molded article with excellent impact resistance is produced at low cost. For this, the resin material that is used includes a mixture resin of recovered resin material obtained by pulverizing a resin material solidified after melting, and virgin resin without thermal history of melting, and a foaming agent added to the mixture resin. The resin material is a mixture of a polypropylene-based resin and a polyethylene-based elastomer.Type: GrantFiled: January 21, 2013Date of Patent: December 27, 2016Assignee: KYORAKU CO., LTD.Inventors: Takeru Sano, Yu Igarashi, Yuki Arita, Takashi Nomura

Patent number: 9022481Abstract: A cushion member includes an intermediate layer, and an upper layer and lower layer stacked and fixed thereto. The cushion member is fixed to a frame by bending an end part of the cushion member so that the upper layer comes to the front side and the lower layer comes to the back side. The intermediate layer is subjected to shear force and the upper layer and the lower layer are subjected to compressive and tensile stress. With the spring characteristic of the intermediate layer, residual stress of the tension and compression is applied to the upper and lower layers from the intermediate layer. Thus, the cushion member can have a restoring property, generation of creases during no load application can be reduced, permanent setting is made less likely, and a compression characteristic in the thickness direction is increased.Type: GrantFiled: March 23, 2012Date of Patent: May 5, 2015Assignee: Delta Tooling Co., Ltd.Inventors: Etsunori Fujita, Yumi Ogura, Seiji Kawasaki, Yuki Arita
