Patent Images
1. 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.

12. 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.

13. 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. - View Dependent Claims (14, 15, 16, 17, 18, 19)
