Title
(EN) INFLATOR DEVICE HAVING MODULAR CONSTRUCTION AND RADIAL INFLATION GAS FLOW
(FR) dispositif de gonflage prÉsentant une construction modulaire et un Écoulement de gaz de gonflage radial
Abstract
(EN)
A modular inflator device for inflating an inflatable cushion of an inflatable cushion restraint system. The inflator device has an elongated cylindrical configuration an includes a supply of gas generant material to produce inflation gas upon reaction initiation. The inflator device includes a reaction housing defining a reaction chamber containing the suppl of gas generant material. An initiator device is connected to the reaction housing and in reaction initiating communication with the supply of gas generant material. The reaction housing includes a plurality of radially oriented chamber discharge openings. Upon reaction initiation of the supply of gas generant material, the inflation gas discharges from the reaction chamber through the discharge openings. An initiator diffuser is disposed between the initiator device and the supply of gas generant material. The initiator diffuser includes a plurality o radially oriented diffuser discharge openings disposed in discharge orientation toward th reaction housing side wall. The reaction housing is connected to a filter housing, and a filter element is disposed within the filter housing and external of the reaction chamber.

L'invention concerne un dispositif de gonflage modulaire servant à gonfler un coussin gonflable d'un système de sécurité à coussin gonflable. Le dispositif de gonflage présente une configuration cylindrique allongée et contient une arrivée de matériau générateur de gaz pour obtenir le gaz de gonflage après déclenchement de la réaction. Le dispositif de gonflage contient un logement de réaction définissant une chambre de réaction contenant l'arrivée de matériau générateur de gaz. Un dispositif initiateur est connecté au logement de réaction et en communication de déclenchement de réaction avec l'arrivée de matériau générateur de gaz. Le logement de réaction comprend une pluralité d'ouvertures de décharge à chambre orientées radialement. Lors du déclenchement de réaction de l'arrivée de matériau générateur de gaz, le gaz de gonflage se décharge à partir de la chambre de réaction à travers les ouvertures de décharge. Un diffuseur initiateur se trouve entre le dispositif initiateur et l'arrivée de matériau générateur de gaz. Le diffuseur initiateur comprend une pluralité d'ouvertures de décharge de diffuseur orientées radialement et disposées en orientation de décharge vers la paroi latérale du logement de réaction. Le logement de réaction est connecté à un logement de filtre, et un élément filtrant se trouve dans le logement de filtre et à l'extérieur de la chambre de réaction.
