Patent number: 7119653Abstract: A fuse element is formed integrally from a conductive metal plate such that two narrow portions are formed side by side between a pair of electrical connection portions. The narrow portions each assume an arch shape and constitute a parallel conductive path. Arch-shaped convex portions are arranged so as to oppose to each other with a predetermined gap therebetween, thus constituting a fusing portion.Type: GrantFiled: May 17, 2002Date of Patent: October 10, 2006Assignee: Yazaki CorporationInventors: Haruhito Ohtsuka, Norio Matsumura

Publication number: 20060090312Abstract: A tongue cover is attached to a grip of a seatbelt tongue such that the tongue cover covers edges of the grip except for an edge to which a plate is attached. The tongue cover may be formed of synthetic resin or rubber that is softer than a resin mold of the grip. The tongue cover, which acts as a cushion, prevents the grip from directly impacting the trim on the inner side wall of a vehicle, thereby substantially reducing the likelihood that the trim will be scratched and/or dented. Moreover, the tongue cover also substantially reduces and/or eliminates noise that is typically caused when a tongue directly impacts trim on the inner side of a vehicle, in the absence of such a tongue cover.Type: ApplicationFiled: October 4, 2005Publication date: May 4, 2006Inventors: Yoshiyuki Ichida, Norio Matsumura, Yuichi Sawatari, Toshiyuki Konishi
