Title
(EN) GAS PRESSURE RESTRAINT, SENSING AND RELEASE SYSTEMS
(FR) SYSTEMES DE RETENUE, DE DETECTION ET DE LIBERATION DE GAZ SOUS PRESSION
Abstract
(EN)
Systems for inflating a vehicular gas bag (10) with gas from a bottle of compressed gas (12) against an occupant (13) in an emergency include a gas pressure sensor (39) having a sensor input (20) coupled to compressed gas in the bottle prior to an emergency, and having a sensed pressure output (21). A variable gas inlet passage (15) for the gas bag has a gas inlet passage variator (22) coupled to the sensed pressure output (21), and a variable gas venting passage (16) positioned in circumvention of the gas inlet passage and inverse to the variable gas inlet passage (see 37 vs. 34), and having a gas venting passage variator (23) coupled to the sensed pressure output. A compressed gas release (25) having a compressed gas outlet (26) on the bottle is connected to the gas inlet passage (15) and to the variable gas venting passage (16). The gas pressure sensor (21) may be temperature-compensated (46-48). Gas discharge from the bottle (12) to the bag (10) may be shaped, such as with the aid of a temporary compressed gas flow restriction (52, 54, 55), for a more controlled gas discharge from the bottle or for a more gentle inflation of the gas bag.

Des systèmes permettant de gonfler un coussin gonflable de sécurité (10) de véhicule avec du gaz contenu dans une bouteille de gaz comprimé (12) contre un occupant (13) du véhicule dans un cas d'urgence comprennent un capteur (39) de pression du gaz comportant une entrée (20) de capteur qui est couplée au gaz comprimé qui se trouve dans la bouteille avant que survienne un accident, et une sortie (21) de la pression détectée. Un passage (15) d'entrée variable pour le gaz associé au coussin gonflable comporte un variateur (22) du passage d'entrée pour le gaz qui est couplé à la sortie (21) de pression détectée et un passage (16) de décharge variable pour le gaz qui est positionné autour du passage d'entrée pour le gaz et dans le sens opposé au passage d'entrée variable pour le gaz (voir 37 par rapport à 34) et qui comporte un variateur (23) du passage de décharge du gaz couplé à la sortie de la pression détectée. Un dispositif (25) de déblocage du gaz comprimé comportant une sortie (26) pour le gaz comprimé située sur la bouteille est connecté au passage (15) d'entrée du gaz et au passage (16) de décharge variable du gaz. Le capteur (21) de pression du gaz peut être à compensation thermique (46-48). La sortie de gaz de la bouteille (12) jusqu'au coussin (10) peut être adaptée à la forme, à l'aide par exemple d'un limitateur (52, 54, 55) d'écoulement temporaire du gaz comprimé en vue d'obtenir une sortie de gaz plus régulée de la bouteille ou un gonflage plus modéré du coussin gonflable de sécurité.
