Patent ID: 7766384

Claim:
Airbag module for protecting vehicle occupants in the event of a collision involving a bag ( 11 ) expandable with gas provided by a generator with, at least, a ventilation orifice ( 13 ) sealed with a patch that comprises an elastic membrane ( 25 ) that breaks as a result of pressure inside the bag ( 11 ) to allow discharging gas, characterized in that: a) the ventilation orifice ( 13 ) is covered with a cover ( 21 ); b) the cover ( 21 ) is secured to the bag ( 11 ) through, at least, one tearable seam ( 31 ) with which the aperture of the ventilation orifice ( 13 ) occurs when the pressure inside the bag ( 11 ) is greater than the breakage pressure of the membrane ( 25 ) increased with additional pressure necessary to tear the seam ( 31 ).
