1. A diffuser for use in an air bag system, the diffuser comprising:
- a connector part configured to be connected about an exit port of an air bag inflator;
a gas distribution part formed as an integral extension of the connector part and configured to deliver gas from the connector part to an inflatable volume of the air bag;
the gas distribution part including a first conduit having a side wall, the first conduit being closed at one end and having a first passage of a first diameter within the first conduit side wall, the first passage terminates at a distal end forming a first distribution port configured to be connected to a first inflatable volume, the first passage intersects the side wall of the connector part forming a first flow chamber between the connector part and first conduit;
the gas distribution part also including a second conduit having a side wall with a second passage therethrough and a distal end forming a second distribution port, the second passage intersecting the first conduit generally opposite the location where the first conduit intersected the side of the connector part, forming an extension of the first flow chamber, gas received in the first flow chamber exiting the diffuser through the first and second passages.

3. A diffuser for use in an air bag system, the diffuser comprising:
-
a body (52) configured to be connected about an exit port of an air bag inflator to receive gas from the inflator, the body including an outer wall (53); and a first gas distribution outlet formed as an integral extension of the body and configured to deliver gas from the connector part to a first portion of the air bag; the first gas distribution outlet (60) including a first side wall (62) with a first passage (64) therethrough, the first side wall being contiguous with the outer wall (53) of the body (52), the first side wall at one end thereof intersecting the body (52), the first passage having an effective first area;
the first side wall, at an end opposite the end that intersects the body, terminates at a distal end (66) configured to be connected to the air bag, the intersection of the first side wall with the outer wall of the body, a first opening communicating the connector part and the first passage;the body including a second gas distribution outlet (70) including a second side wall (72) with a second passage (74) therethrough, a distal end connectable to the air bag;
the second side wall (70) intersecting the first side wall (60) at a location generally opposite the location where the first side wall intersected the outer side of the body forming a second opening communicating the first passage with the second passage. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
