Abstract
A gas generating system is provided including a first housing formed from a polymeric material, and a pyrotechnic gas generant material contained in the first housing. The first housing forms a combustion chamber for the gas generant. An airbag system and a vehicle occupant protection system, each incorporating a gas generating system as described herein, are also disclosed.
Claims19
A gas generating system comprising:
- a polymeric first housing defining an interior;
- a second housing having at least a portion of the first housing positioned therein, the second housing being spaced apart from the first housing;
- a baffle enclosed within the second housing,
- an annular fluid flow passage defined by the first housing and the baffle along a first side of the passage and by the second housing along an opposite side of the passage;
- the baffle incorporating means for preventing a flow of gas from the first housing interior directly into an interior of the baffle both before and after generation of a gas within the first housing interior.

A gas generating system comprising:
- a polymeric first housing;
- a second housing having at least a portion of the first housing positioned therein, the second housing being spaced apart from the first housing;
- so as to define an annular fluid flow passage extending therebetween;
- and
- a baffle enclosed within the second housing, the baffle defining a baffle chamber and having an opening enabling fluid communication between the flow passage and the baffle chamber;
- the baffle incorporating means for preventing a flow of gas from the first housing directly into the baffle chamber both before and after generation of a gas within the first housing;
- wherein all of the gases generated in the first housing are directed radially outwardly from the first housing, then toward the baffle, then radially inwardly into the baffle chamber.

A gas generating system comprising:
- a polymeric first housing;
- a second housing, spaced apart from the first housing;
- a baffle having at least a portion thereof positioned within the second housing, the baffle including a first portion and a wall extending from the first portion, the first portion and the wall defining a baffle chamber,
- an annular fluid flow passage defined by the first housing and the baffle wall along a first side of the passage and by the second housing along an opposite side of the passage;
- the baffle having at least one opening formed in the wall, the at least one opening directly connecting the chamber with the flow passage.
