ABSTRACT:
An actuator device for actuating a supply of gas generant material in an airbag inflator device. The actuator includes an initiator cup having a cup side wall, an end wall at a first end of the cup side wall, and a cup open end at a second end of the cup side wall opposite the end wall. A header body is connected to the initiator cup at the second end of the cup side wall. The header body and the initiator cup define a storage chamber. A radial discharge charge holder is disposed within the storage chamber and adjacent the header body. The charge holder includes a charge holder side wall substantially parallel to at least a portion of the cup side wall, a charge holder open end disposed toward the initiator cup end wall, and at least one discharge opening disposed in the charge holder side wall. The actuator device includes an inner canister with at least a portion of the inner canister disposed over the charge holder open end to define a charge holder chamber. A first reactive charge is disposed within the charge holder chamber, and a second reactive charge including a fluid or a gel is disposed within the storage chamber between the inner canister and the initiator cup end wall.
