Abstract
An initiator assembly includes an SMI assembly board onto which at least a first and a second initiator are surface mounted. The first and second initiators each include a respective surface mount initiator board with which a respective igniter element is respectively mounted. Corresponding multi-initiator assemblies for automotive airbag inflator devices as well as automotive airbag inflator device combinations are also provided.

An initiator assembly comprising:
- an SMI assembly board onto which at least a first and a second initiator are surface mounted, the first initiator comprising;
- a first container closed by a first solid body, the first container containing a supply of a first igniter material;
- a first igniter element disposed within the first container, upon actuation, the first igniter element in reaction initiating communication with the first igniter material;
- a first surface mount initiator board disposed between the first igniter element and the first solid body and
- first initiator first and second electrical contacts passing through the first solid body and the first surface mount initiator board in electrical contact with the first igniter element;
- the second initiator comprising;
- a second container closed by a second solid body, the second container containing a supply of a second igniter material;
- a second igniter element disposed within the second container, upon actuation, the second igniter element in reaction initiating communication with the second igniter material;
- a second surface mount initiator board disposed between the second igniter element and the second solid body and
- second initiator first and second electrical contacts passing through the second solid body and the second surface mount initiator board in electrical contact with the second igniter element.
