ABSTRACT
A hybrid inflator has flame-transferring holes 118 which allow outflow of a booster gas, and first communication holes 125 which allow outflow of a combustion gas are arranged in the same position in the longitudinal direction of the hybrid inflator to render smooth outflow of the booster gas and the combustion gas.
BACKGROUND OF THE INVÈNTION
1. Field of the Invention
This invèntion relates to an inflating-type safety system of motor vehicles, and more particularly to a hybrid inflator capable of inflating an air bag rapidly and unfailingly and an air bag system using the same inflator.
2. Description of Related Art
With the development of an inflator for an inflating-type safety system of motor vehicles, a hybrid inflator using both a pressurized gas and a solid gas generating agent is attracting attention. A main design requirement for a hybrid inflator is that the inflator inflates an air bag by a predetermined amount in a predetermined time so that the air bag is effectively activated. Various proposals concerning a structure to meet the requirement have heretofore been made (for example, as referred in JP-A8-282427). In order to secure safety of an occupant, it is important for such a hybrid inflator to inflate the air bag unfailingly.
