It is an object of the present invention to ensure that in an air bag device including a control valve capable of opening and closing a vent hole provided in a retainer, a sufficient opening degree of the control valve can be ensured by use of a small-sized and inexpensive actuator. For this purpose, the control valve for opening and closing the vent hole defined in the retainer supporting an inflator and an air bag in the air bag device is opened and closed by eight valve members each operated by a piezoelectric element serving as an actuator. The plurality of divided valve members of the control valve are used and hence, even if the size of the piezoelectric element for operating each of the valve members is reduced to provide a reduction in cost, a sufficient opening degree of the entire control valve can be ensured.
An air bag device including an inflator accommodated in a retainer to which a peripheral edge of an opening of a folded-up air bag is fixed, so that said air bag is deployed by a gas generated by said inflator upon collision of a vehicle to restrain an occupant, wherein a vent hole defined in said retainer can be opened and closed by a control valve operated by an actuator, said control valve including a plurality of divided valve members.
An air bag device including an inflator accommodated in a retainer to which a peripheral edge of an opening of a folded-up air bag is fixed, so that said air bag is deployed by a gas generated by said inflator upon collision of a vehicle to restrain an occupant, wherein the opening degree of a vent hole defined in said retainer can be controlled by a control valve operated by an actuator, said control valve including a valve member, which is formed of an elastomer material and supported to cover said vent hole from the outside, so that when said vent hole is opened by a gas generated by said inflator, said actuator generates a load in a direction to close or open the vent hole by said valve member of said control valve.
An air bag device including an inflator accommodated in a retainer to which a peripheral edge of an opening of a folded-up air bag is fixed, so that said air bag is deployed by a gas generated by said inflator upon collision of a vehicle to restrain an occupant, wherein a vent hole defined in said retainer can be opened and closed by a control valve having a valve member operated by an actuator, and said air bag device includes a stopper for limiting the maximum opening degree of said valve member of said control valve.
