An inflatable vehicle occupant restraint (12) includes a first fabric panel (60), a second fabric panel (62), and a seam (64) at which the fabric panels (60,62) are fastened to each other. The restraint (12) further includes a vent opening (128) which interrupts the seam (64) to direct inflation fluid to exit the restraint (12) between the fabric panels (60,62). The restraint (12) is inflated between a vehicle seat (16) and an adjacent vehicle door (18) upon the occurrence of a side impact collision, and protects an occupant of the seat (16) from being forcefully struck by the door (18). The vent opening (128) directs the inflation fluid to exit the restraint (12) in a direction which is perpendicular to the direction in which the door (18) is moved toward the seat (16) by the side impact collision. As a result, the flow of inflation fluid which is directed from the restraint (12) through the vent opening (128) is directed away from the occupant and is not blocked or impeded substantially by the seat (16) or the door (18).
Cette invention concerne un coussin gonflable de sécurité automobile (12) formé d'un premier panneau de tissu (60) et d'un second panneau de tissu (62) réunis par une couture (64). Le coussin gonflable (12) comporte également un orifice d'évacuation (128) sur la ligne de couture (64), qui sert à rejeter à l'atmosphère le fluide ayant servi à le gonfler. Sur impact latéral du véhicule, le coussin (12) se gonfle entre le siège (16) et la portière (18) correspondante pour protéger l'occupant du siège (16). L'orifice d'évacuation (128) est orienté dans une direction perpendiculaire au sens de déplacement de la portière (18) vers le siège (16), sur impact latéral. De cette manière, le fluide de gonflage s'échappant du coussin (12) par l'orifice (128) s'éloigne de l'occupant du siège (16) et son flux ne risque pas d'être bloqué ou ralenti par ledit siège (16) ou la portière (18).
