1. A gas generating system comprising:
- a cylindrical housing having at least a first and a second gas exit orifices formed therealong;
a first deflector portion attached directly to an exterior of the housing at a first attachment location angularly spaced apart from a location of the first gas exit orifice, so as to cover the first gas exit orifice, the first deflector portion having a first free end angularly spaced apart from the first attachment location and in direct contact with the housing prior to activation of the gas generating system; and
a second deflector portion attached directly to an exterior of the housing at a second attachment location angularly spaced apart from a location of the second gas exit orifice and also from the first attachment location, so as to cover the second gas exit orifice, the second deflector portion having a second free end angularly spaced apart from the second attachment location and in direct contact with the housing prior to activation of the gas generating system, the second free end being angularly spaced apart from the first free end so as to define a first gap between the first and second deflector portions at the first and second free ends,the first and second deflector portions being structured so that the free ends of the each of the first and second deflector portions deflect in a direction away from the housing responsive to gases exiting the housing and impinging upon the deflector portions.

Abstract
A gas generating system is presented that contains a gas deflector positioned about an associated gas generator. The deflector may be attached to an outer wall of a perforate housing of the gas generator, or, alternatively, the deflector may be attached to a support structure positioned about the perforate housing, whereby gases exiting the gas generator upon actuation thereof, impinge upon the deflector.

8. A gas generating system comprising:
-
a cylindrical housing having at least first, second, third, and fourth gas exit orifices formed therealong; a first deflector portion attached directly to an exterior of the housing at a first attachment location angularly spaced apart from a location of the first gas exit orifice, so as to cover the first gas exit orifice, the first deflector portion having a first free end angularly spaced apart from the first attachment location and in direct contact with the housing prior to activation of the gas generating system; and a second deflector portion attached directly to an exterior of the housing at a second attachment location angularly spaced apart from a location of the second gas exit orifice, so as to cover the second gas exit orifice, the second deflector portion having a second free end angularly spaced apart from the second attachment location and in direct contact with the housing prior to activation of the gas generating system, the second free end being angularly spaced apart from the first free end so as to define a first gap between the first and second deflector portions at the first and second free ends, a third deflector portion attached directly to an exterior of the housing at the first attachment location so as to cover the third gas exit orifice, the third gas exit orifice angularly spaced apart from the first attachment location, the third deflector portion having a third free end angularly spaced apart from the first attachment location and in direct contact with the housing prior to activation of the gas generating system; and a fourth deflector portion attached directly to an exterior of the housing at the second attachment location so as to cover the fourth gas exit orifice, the fourth gas exit orifice being angularly spaced apart from the second attachment location, the fourth deflector portion having a fourth free end angularly spaced apart from the second attachment location and in direct contact with the housing prior to activation of the gas generating system, the fourth free end being angularly spaced apart from the third free end so as to define a second gap between the third and fourth deflector portions at the third and fourth free ends, the first and second deflector portions being structured so that the free ends of each of the first and second deflector portions deflect in a direction away from the housing responsive to gases exiting the housing and impinging upon the deflector portions, and such that gases flowing off of the first deflector free end and through the first gap are urged in a first direction, and gases flowing off of the second deflector free end and through the first gap are urged in a second direction converging with the first direction, and the third and fourth deflector portions being structured so that the free ends of each of the third and fourth deflector portions deflect in a direction away from the housing responsive to gases exiting the housing and impinging upon the deflector portions, and such that gases flowing off of the third deflector free end and through the second gap are urged in a third direction, and gases flowing off of the fourth deflector free end and through the second gap are urged in a fourth direction converging with the third direction. - View Dependent Claims (9, 10)

11. A gas generating system comprising:
-
a cylindrical housing having a plurality gas exit orifices formed therealong; and a first deflector portion attached directly to an exterior of the housing at a first attachment location angularly spaced apart from the gas exit orifices, so as to cover the first gas exit orifice, the first deflector portion having a first free end angularly spaced apart from the first attachment location and in direct contact with the housing prior to activation of the gas generating system; a second deflector portion attached directly to an exterior of the housing at a second attachment location angularly spaced apart from the gas exit orifices and also from the first attachment location, so as to cover the second gas exit orifice, the second deflector portion having a second free end angularly spaced apart from the second attachment location and in direct contact with the housing prior to activation of the gas generating system, the second free end being angularly spaced apart from the first free end so as to define a first gap between the first and second deflector portions at the first and second free ends such that gases exiting the housing and impinging upon the first and second deflector portions are directed through the first gap; a third deflector portion attached directly to an exterior of the housing at the first attachment location so as to cover a third gas exit orifice, the third deflector portion having a third free end angularly spaced apart from the first attachment location and in direct contact with the housing prior to activation of the gas generating system; and a fourth deflector portion attached directly to an exterior of the housing at the second attachment location so as to cover a fourth gas exit orifice, the fourth deflector portion having a fourth free end angularly spaced apart from the second attachment location and in direct contact with the housing prior to activation of the gas generating system, the fourth free end being angularly spaced apart from the third free end so as to define a second gap between the third and fourth deflector portions at the third and fourth free ends, such that gases exiting the housing and impinging upon the third and fourth deflector portions are directed through the second gap. - View Dependent Claims (12, 13, 14)
