Gas generator
First Claim
1. A gas generator, comprising:
- a housing defining an interior and having an ignition end and a discharge end, an ignition unit disposed within the interior of the housing at the ignition end, at least one discharge opening disposed at or near the discharge end of the housing and communicating between the interior and an exterior surface of the housing, a cooling system disposed within the interior of the house, at least a portion of which is tapered so as to generally decrease in diameter toward the discharge end, and a gas generating mixture disposed within the cooling system.

Abstract
A pyrotechnical gas generator, preferably for an airbag system, consists of a housing, an ignition unit, a gas generating mixture, a conically shaped cooling system (or cooling and filtering system) tapering in the discharge direction, a gas generating mixture disposed within the cooling system. The housing is preferably one piece and tubular. The combustion gases are discharged through exit ports arranged radially, axially or diagonally on a side of the housing opposite the ignition unit. The cooling system (or cooling and filtering system) separates the gas generator into a combustion chamber, which contains the gas generating mixture and in which a gas is generated by burning the gas generating mixture, and an outflow chamber, through which the cooled (and optionally filtered) gas can flow and the exit through the exit ports. The conical arrangement of the cooling system (or cooling and filtering system) tapering in the discharge direction achieves an optimum effect as regards cooling and filtering, accompanied by a minimum of space requirements and a reduction in weight.
