First Claim
1. An inflator for inflating an inflatable vehicle occupant protection device, comprising:
- a container in which inflation fluid is stored under pressure, said container having an opening through which inflation fluid flows from said container;
a rupturable closure member fixed to said container and blocking flow of inflation fluid through said opening;
an initiator for, when actuated, rupturing said closure member to enable inflation fluid to flow from said container through said opening; and
a retainer for retaining said initiator on said container, said retainer comprising first and second parts that are movable relative to each other when said retainer is not connected with said container;
said first and second retainer parts when connected with said container cooperating to clamp said initiator in position on said container;
said first and second retainer parts defining a fluid outlet through which inflation fluid flows from said opening to exit said inflator.

Abstract
An inflator (10) comprises a container (30) in which inflation fluid is stored under pressure. The container (30) has an opening (40) through which inflation fluid flows from the container. A rupturable closure member (60) is fixed to the container (30) and blocks flow of inflation fluid through the opening (40). The inflator includes an initiator (70) for, when actuated, rupturing the closure member (60) to enable inflation fluid to flow from the container through the opening (40). The inflator (10) also includes a retainer (90) for retaining the initiator (70) on the container (30). The retainer (90) comprises first and second parts (92, 94) that are movable relative to each other when the retainer is not connected with the container (30). The first and second retainer parts (92, 94) when connected with the container (30) cooperate to clamp the initiator (70) in position on the container. The first and second retainer parts (92, 94) define a fluid outlet (108, 140) through which inflation fluid flows from the opening (40) to exit the inflator (10).
