Patent number: 10676119Abstract: There is provided a steering wheel to make it possible to install a covering member on a rim section main body portion in a wide range and with a good external appearance. A steering wheel base section includes the rim section main body portion that configures a rim section. The rim section main body portion is provided with a groove along the rim section main body portion. The groove is provided with a first line-shaped groove and a second line-shaped groove that is less bent than the first groove. The covering member is wrapped around the rim section main body portion of the steering wheel base section. The covering member is provided with divergence covering sections disposed along the first groove with the first groove interposed therebetween. The covering member straddles the second groove at a position of the second groove and connects the divergence covering sections by a covering base portion.Type: GrantFiled: December 27, 2018Date of Patent: June 9, 2020Assignee: NIHON PLAST CO., LTD.Inventors: Akihiko Yamami, Katsuya Muramatsu, Masahiro Ooka

Patent number: 10358110Abstract: An airbag includes: an airbag body formed in a bag shape with an occupant-side panel facing an occupant and an opposite-side panel facing a steering wheel in a deployed state; and a flow regulator arranged inside the airbag body and configured to regulate a direction of flow of gas supplied from an inflator. The flow regulator includes: a flow-regulator body arranged such that at least part of the flow-regulator body faces the inflator; fixed portions provided at mutually separated positions on the flow-regulator body and fixed to the opposite-side panel; and a notch provided between the fixed portions in a recessed shape toward a center of the flow-regulator body and forming a gas passage port between the notch and the opposite-side panel, the gas passage port being a port through which the gas supplied from the inflator flows.Type: GrantFiled: June 30, 2017Date of Patent: July 23, 2019Assignee: NIHON PLAST CO., LTD.Inventors: Masahiro Ooka, Yohei Kiuchi, Akihiko Yamami, Yuta Inaba

Patent number: 10196028Abstract: A steering wheel includes a steering wheel body including at least two insertion openings, and an airbag module including at least two hooks inserted into the insertion openings. The hooks are held by wires so that the airbag module is supported by the steering wheel body. Either the at least two hooks or the at least two insertion holes are provided with adjustment ribs which come into contact with the other ones of the at least two hooks and the at least two openings, thereby regulating the positions of the other ones, so as to receive the weight of the airbag module applied to the steering wheel body. Accordingly, a decrease in positioning performance of the airbag module is prevented, so as to regulate the position of the airbag module in the steering wheel body with high accuracy.Type: GrantFiled: March 29, 2017Date of Patent: February 5, 2019Assignee: NIHON PLAST CO., LTD.Inventors: Akihiko Yamami, Yohei Kiuchi, Yuta Inaba, Takashi Mitobe

Publication number: 20180273078Abstract: A spacer is interposed between a rim core metal and an electronic part, so that the electronic part can be easily disposed. An opening is formed in the spacer such that the opening is positioned to face an overflow portion that is formed in a mold for molding of a resin layer and that is provided for a fluid synthetic resin raw material to overflow. Even when air bubbles are generated in the synthetic resin raw material between the spacer and a core metal, the synthetic resin raw material overflowing to the overflow portion can easily eject the air bubbles to the overflow portion via the opening and the air bubbles can be prevented from remaining in the resin layer.Type: ApplicationFiled: March 23, 2018Publication date: September 27, 2018Inventors: Takashi MITOBE, Akihiko YAMAMI, Nobutaka UEMATSU, Yuta INABA

Patent number: 8807589Abstract: A base plate portion 21 directly receiving face pressure of the airbag is provided with a steel plate 31 made of a metal, and a stack portion 33 having a resin layers 32 made of synthetic resin and overlapping both faces of the steel plate 31. It possible to uniformly generate stress on both faces of the steel plate 31 in contraction at the time of molding while ensuring sufficient strength against the expansion pressure of the airbag, so that it is possible to suppress deformation in a cooling process after the molding and dimensional stability is high. The peripheral wall portion 22 is able to ensure sufficient strength even when it is integrally formed with each resin layer 32 of the base plate portion 21 in the form of a single layer.Type: GrantFiled: March 15, 2013Date of Patent: August 19, 2014Assignee: Nihon Plast Co., Ltd.Inventor: Akihiko Yamami
