A gas generator includes: a housing having closure and diffuser shells; an inner tube member accommodating an igniter, an opening end of the inner tube member being located opposing a bottom plate of the closure shell and defining a ventilating portion formed at the opening end,

Gas generator for restraining device of vehicle

A gas generator, includes: a housing having closure shell, a diffuser shell including a gas discharge ports, and a flange portion; an inner tube member defining a combustion chamber in an outside thereof for accommodating a gas generating agent,

An inflator () comprised of an inner case () and an outer case (). The inflator () includes a combustion chamber located inside the inner case (), a plurality of gas discharge ports () formed on the outer case (), a gas outlet port () formed on an outer surface of the inner case () and a gas guide section that guides the inflation gas exited the gas outlet port () toward the gas discharge ports (). The gas guide section includes between the outer case () and inner case () a guide wall () provided with a guide plane that contacts with and redirects the inflation gas. The guide plane is formed into an arc face so as to swivel the inflation gas exited the gas outlet port () in a swirl or helical fashion, guide the inflation gas toward the gas discharge ports () and capture residuals.

Inflator

An inflator includes in a combustion chamber a first gas generating charge and a second gas generating charge to be ignited and burned to generate an inflation gas. The second gas generating charge is slower in speed of combustion than the first gas generating charge. The inflator further includes a partition wall that segregates the first and second gas generating charges. The partition wall is located away from an ignition area of an ignition device that ignites the first gas generating charge, with the first gas generating charge located between itself and the ignition area. The partition wall is burnable to destruction by the fire generated by combustion of the first gas generating charge so as to permit propagation of the fire to the second gas generating charge by its generally entire area.

The airbag apparatus is provided with a retainer that includes a hold-down portion for attachment of a periphery of a gas inlet of an airbag to the case, a cover wall surrounding an inflator body, deflectors and catches. The cover wall includes a plurality of outlet ports for releasing inflation gas exited discharge ports of the inflator body radially. The deflectors deflect the inflation gas exited the outlet ports in a range of angle from a direction orthogonal to an axis of the inflator body to a downward direction extending toward the hold-down portion. The catches capture residual particles contained in the inflation gas when the gas deflected by the deflectors hit them.

The present invention provides a cellulose ester in which heat resistance under wet condition is compatible with both releasability and spinnability even when the amount of the residual solvent is small in a casting process. The cellulose ester fulfills the following formula:0.5&#x3c;()/()&#x3c;1.5 wherein (A) and (B) represent the total amount (in terms of molar amount) of residual sulfuric acid in 1 gram of the cellulose ester and the total amount (in terms of molar amount) of calcium contained in 1 gram of the cellulose ester, respectively.

Cellulose ester having improved stability to wet heat

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

The present invention provides (meth)acrylate compounds bearing a specific maleimide group and resin compositions containing said compounds that can be cured by irradiation of light in a practical dose even when a photoinitiator is not used or used in a smaller amount than that of the prior art, and cured articles of the resin compositions.

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.

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.

The present invention provides a cellulose triacetate which exhibits a satisfactory filtration performance Thus, the present invention provides a cellulose triacetate whose occlusion constant (K) determined by the following method is 70 or less. Method: the cellulose triacetate is dissolved in a solvent mixture of methylene chloride/methanol (9/1 w/w) to form a 16% by weight (as a solid concentration) solution, which is then filtered under a constant pressure at the filtration pressure of 3 kg/cm and the temperature of 25&deg; C. using a muslin filter to determine a filtered volume with the lapse of time, from which the slope of a linear curve represented by t/V&minus;t (wherein t is a filtration time (sec) and V is a filtered volume (ml)) is calculated to obtain an occlusion constant (K) where K&equals;slope&times;2&times;10 .
