Patent number: 6648369Abstract: An inflatable belt for use in a seat belt apparatus. The belt provides an increased inflation length without having to pass an inflatable bag through a belt guide. A seat belt apparatus may include the air belt which may include a webbing of which at least a part that comes into contact with an occupant is formed as a bag-like portion and the remaining part is formed as a single-band portion. The apparatus has a bag stored in the bag-like portion of the webbing in such a manner that the bag is folded along both the longitudinal direction thereof and the direction perpendicular to the longitudinal direction thereof. The air belt includes cover that covers the webbing. When a gas is injected into the bag the bag inflates to expand the webbing and to provide EA effect and occupant protection.Type: GrantFiled: December 18, 2001Date of Patent: November 18, 2003Assignee: Takata CorporationInventors: Masaru Mishima, Akira Kokeguchi
