Abstract
The present invention provides a gas generator for air bags that includes a first shell having a circular part and an outer wall. The outer wall is formed of a porous material which allows gas to pass freely therethrough. A second shell is attached to the first shell to form a housing into which is installed a gas generating device. A plurality of first and second blade members fasten the first and second shells together. The blade members are placed in contact with the circumferential surface of the canister and arranged along the circumference of the canister at periodic intervals to form a ring. The second blade members have a width at least equal to the circumferential interval between the first blade members and are spaced radially from the first blade members and shifted in the circumferential direction from the first blade members to positions facing the intervals between the first blade members. Gas is produced by the gas generating device, upon receiving impacts, delivered passed the blade members and introduced through the outer wall of the first shell, into the air bag to protect the passenger from an impact.
