Abstract
An initiator (,) for rupturing a burst disk (,) in an air bag inflator (,) includes a body of ignitable material (,) for, when ignited, generating combustion products. A base (,) supports the body of ignitable material (,), and an electrically energizable member (,) for igniting the ignitable material, on the inflator (,). The initiator (,) also includes a cap (,) sealed to the base (,). The cap (,) encloses the ignitable material (,) and maintains the ignitable material in position on the base (,). At least a first portion (,) of the cap (,) is releasable from the base (,) under the force of the combustion products of the ignitable material (,) to enable movement of at least the first portion of the cap away from the base and into engagement with the burst disk (,) to rupture the burst disk.
