A side air bag expands near a window at a time of collision of a vehicle to restrain an occupant from moving in a lateral direction. The air bag has an expansion durationprotractedwhich is extendedto constrain the occupant during overturning of the vehicle. Stowability for stowing the air bag in a folded state in a side structure of the vehicle, such as a pillar and a roof side rail portion, is enhanced in that two woven fabrics are connected along an outer peripheral portion,to form a bag portion, bya textile structure woven using a common yarninclude inofbothfabricsfabric sheets forming opposing sides of the air bag. A whole of the bag portion is coated and sealed by an airnon-permeableimpermeablecoating material to improve air tightness. A mounting portion for mounting the air bag in the side structure, such as a pillar or a roof side rail, is integrally formed by extending the woven fabrics or the common-yarn textile structure portion outward from the outer peripheral connection portion, thereby improving stowability.

Side air bag

An air bag system for protecting a passenger seated on the front passenger seat of a vehicle. In an initial stage, the air bag is inflated mildly. In the subsequent stage, the bag is inflated also mildly. The directivity of produced gas can be reduced. The air bag can be inflated mildly while maintaining a large area. The air bag system comprises an inflator, the aforementioned air bag being folded, and a diffuser mounted about the inflator. The air bag is placed in a side-by-side relation to the inflator and located behind the inflator. The diffuser is provided with numerous holes for supplying the gas. The diffuser acts to regulate flow of the gas from the inflator.

Air bag system for automotive passenger seat

An air bag system for protecting a passenger seated on the front passenger seat of a vehicle. In an initial stage, the air bag is inflated mildly. In the subsequent stage, the bag is inflated also mildly. The directivity of produced gas can be reduced. The air bag can be inflated mildly while maintaining a large area. The air bag system comprises an air bag case having an opening on its top side, an inflator disposed inside the air bag case, the aforementioned air bag folded in the air bag case, and a diffuser mounted between the inflator and the opening in the case. The air bag is placed in a side-by-side relation to the inflator and located behind the inflator inside the case. The diffuser is provided with numerous holes for supplying the gas. The diffuser acts to regulate flow of the gas from the inflator. At least when the gas is produced from the inflator, a space is created between the outer surface of the inflator and the diffuser.

In an airbag device ( ) wherein within a casing ( ) opening upwardly an inflator ( ) and an airbag ( ) are housed at its bottom part and the opening side, respectively, a cylindrical diffuser ( ) surrounding the outer circumference of the inflator ( ) is provided, which has a partition wall ( ) projecting toward the opening side of the casing and partitioning an airbag-housing space into a forward side and a rearward side relative to the vehicle, in which to house the airbag ( ) dividedly, and a lip portion ( ) of the airbag ( ) is superposed downwards of the diffuser ( ) thereby to lock the bottom part of the diffuser ( ) to the bottom surface of the casing ( ). Thus, it is easy, albeit compart, to control the deployment behavior of the airbag and excellent in workability of assembling the airbag in the casing.

Instrument panel for air bag

A side air bag expands near a window at a time of collision of a vehicle to restrain an occupant from moving in a lateral direction. The air bag has an expansion duration protracted to constrain the occupant during overturning of the vehicle. Stowability for stowing the air bag in a folded state in a side structure of the vehicle, such as a pillar and a roof side rail portion, is enhanced in that two woven fabrics are connected along an outer peripheral portion to form a bag portion a textile structure woven using a common yarn include in both fabrics. A whole of the bag portion is coated and sealed by an air non-permeable coating material to improve air tightness. A mounting portion for mounting the air bag in the side structure, such as a pillar or a roof side rail, is integrally formed by extending the woven fabrics or the common-yarn textile structure portion outward from the outer peripheral connection portion, thereby improving stowability.

Airbag for front seat passenger

Side air bag device

An inflatable bag,for airbag restraint systems for a front seat passenger, of a quadrilateral prismoidal shape comprising a right-angled quadrilateral base portion adapted to face and receive the passenger by the extension of the bag upon deployment, a lip portion defining an opening for admitting gas from the system and adapted to be attached to a dashboard, upper and lower face portions, and lateral face portions having T-like or Y-like joints diverging from the lip to base portions and exhibiting a strap effect. The bag is made of a one-piece cloth, each outlining lateral side of which has longitudinally consecutive six sides of three triangular sections wherein two endmost sides and respective two adjoining sides have respectively an equal length, or longitudinally consecutive five sides wherein two endmost sides have an equal length and other two sides adjacent to the former have a total length equal to the length of a longitudinal side therebetween. When the cloth is longitudinally folded into two, the endmost sides are superposed and sewed together. Then, respective adjoining sides are superposed and sewed together, thus forming the Y-like joints and lateral face portions, or other two sides are superposed onto the longitudinal side and sewed together, thus forming the T-like joints and lateral portions, thereby shaping the prismoidal body, which is turned inside out to give the bag. The endmost sides may assume an arc-like line.
