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 invention relates to an airbag module for automotive vehicles, comprising a gas generator (15) and an inflatable cushion (13) which are housed in a container (11) which is prismatic in shape and formed by folding a flat sheet of suitable material in which its large sides (31, 33), its back side (35) and, as extensions of the sides of said large sides (31), flaps (37, 37?, 37?) corresponding to the sides of the closing surface of the container (11), are defined by means of pre-cut lines, said flaps (37, 37?, 37?) and the large side (33) they are separated from including cooperating means (41, 43, 45) defined by means of pre-cut lines, which allow closing the container (11). The container (11) additionally includes means (51, 53) defined by means of pre-cut lines intended for aiding in positioning and fixing the airbag module in the vehicle.

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.

Abstract: Airbag module for a car that consists of a bag (11) consisting of at least two chambers (13, 15) inflatable with gas produced by a generator (21) and providing to each one of them via outlets from a distributor conduit (23) connected to the generator (21); the outlets would be configured to provide varying gas pressure in such chambers (13, 15) that also include a diffuser (31, 33, 35, 37) associated to said distribution conduit 823) in order to prevent the passage of gas between the chambers (13, 15) through such distribution conduit (23) after finishing the gas supply from the generator (21) in order to maintain different pressure levels in both chambers (13, 15) during the entire interaction period with the occupant.
