Abstract: The invention relates to a side airbag module for an automotive vehicle which includes an inflatable bag (11) configured to be deployed between an occupant and the vehicle body upon being filled with the gas produced by a generator, which bag comprises a front panel (21) intended to make contact with the occupant, a rear panel (23) and at least one inner panel (25) forming a first chamber (13) with the rear panel (23) and a second chamber (15) with the front panel (21), having a vent hole (19), the inner panel (25) including a duct (39) allowing the passage of gas from the first chamber (13) to the second chamber (15) and which is located in a position allowing it to be blocked upon the front panel (21) moving closer to the inner panel (25) during the contact of the bag (11) with the occupant.

Abstract: Airbag module for protecting an occupant of car with a bag (11) that includes a main front panel (17) and main rear panel (19) connected by its ends and a retention band (21) connected to the panels in two opposite ends (31, 33), capable of withstanding maximum pressure during the unfolding of the bag (11) without breaking or disconnecting from said panels, and whose length L is less than the maximum distance D that would exist between said opposite areas (31, 33) during the unfolding of the bag should said retention band (21) not exist; the bag has a ventilation orifice (23) around one of the union areas (31, 33) that can be covered by the main front and rear panels (17, 19) when the bag (11) contacts the occupant (15).

Abstract: The present invention relates to a side airbag for an automotive vehicle comprising a venting regulation device formed by a part made of a flexible material (21) joined to the inflatable cushion (11) such that it can completely or partially close or free the venting opening (17), and a tension belt (23) joined by one part to said part made of a flexible material (21) and by another part to the inflatable cushion (11), the geometric configurations of said tension belt (23) and said part made of a flexible material (21) being determined such that the degree of closing/freeing of the venting opening (17) varies according to the width of the inflatable cushion (11) during its different deployment phases during the collision, being closed in the initial and end phases and freed in the intermediate phase.

Abstract: An airbag for automotive vehicles with a gas venting regulation device assembled around a venting opening (11) comprising a first part (15) joined to the inflatable cushion (13) covering the venting opening (11), formed by an elastic area (31) and a non-elastic area (33) with a plurality of openings (17, 19) for the passage of gas; a second rigid part (21) joined to the inflatable cushion (13) and to the first part (15), with a projecting neck (23) forming a gas outlet mouth; and in which at least one part of the non-elastic area (33) is arranged such that when the first part (15) is deformed as a result of the internal pressure in the inflatable cushion during its deployment, the passage of gas through the openings (17) is completely or partially sealed by the projecting neck (23).

Abstract: The invention relates to an airbag module for an automotive vehicle comprising an inflatable cushion (11) which is inflated with the gas produced by a generator when a collision occurs and which is configured to deploy between an occupant (13) of the vehicle and an area (15) of the vehicle, in which in order to improve its adaptivity to impacts of different severities, the cushion (11) includes a venting area with surface Su distributed in a plurality of openings (23), preferably circular shaped, the sum of their perimeters being comprised between 4 and 40 times, and preferably between 6 and 18 times, the perimeter of a circle with surface Su. The invention can be applied to frontal and side airbag modules.
