摘要:
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).
摘要:
Airbag module to protect a vehicle occupant in the event of a collision comprising an expandable bag (11) with gas provided by a generator with, at least, one ventilation orifice (13) sealed with a patch that comprises an elastic membrane (25) destined to be broken as a result of pressure inside the bag (11) to allow gas discharge through the ventilation orifice (13), which is covered with a cover (21) secured to the bag (11) with, at least, one tearable seam (31); hence the opening of the ventilation orifice (13) occurs when the pressure inside the bag (11) is greater than the pressure required to break the membrane (25) plus the additional pressure necessary to tear the seam (31). The invention also comprises a procedure to manufacture the bag.
摘要:
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.
摘要:
The present invention relates to 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 said first part (15), with a projecting neck (23) forming a gas outlet mouth; and in eihich at least one part of said 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 said openings (17) is completely or partially sealed by said projecting neck (23.
摘要:
An automotive vehicle seat (3) with an airbag intended for restraining its occupant (9) in the event of a side impact, comprising a bag (15), including a plurality of cells (31, 33, 35, 37), sized so as to protect the pelvis, abdomen, thorax and head of the occupant, located in the backrest (5) of the seat (3) wrapped in a flexible case and provided with at least two fixing points (25, 27) to fix it to the backrest (5) of the seat (3), which is inflated with the gas provided by a gas generator (17), separated from the bag, through a diffusing tube (19).
