Overflow channeling reaction canister assembly

摘要

A reaction canister assembly for use in an inflatable airbag module system comprises a reaction canister housing having at least one open side and an inflator chamber. An inflator is disposed in the inflator chamber and includes a plurality of perforations or ports for passing excess gas generated within the inflator into the canister housing. At least one endplate partially closes the open side of the canister to leave an excess gas outlet passage at the open side of the housing. At least one overflow channel extends along a length of the housing for filtering and cooling the excess gas generated by the inflator. The excess gas passes through the ports of the inflator into the overflow channels and is discharged through the excess gas outlet passage at the open side of the housing.
