HYBRID INFLATOR FOR AIRBAGS

摘要

To provide a hybrid inflator in which the combustibility of a second gas generating agent is improved. Some of the openings 121a out of second openings 121 are shielded with tape 132, and the opening area A2nd-1 of the remaining openings and the opening area Aex of an opening portion 131 of a recessed portion of a partition member for controlling an outflow pressure of gas satisfy the relationship Aex ( A2nd-1, whereby the pressure inside a second combustion chamber 120 readily rises upon burning the second gas generating agent 119. The combustibility of the second gas generating agent 119 is thus favorable even when a pressurized medium has been discharged and hence the internal pressure has become equal to atmospheric pressure.
