Abstract
An apparatus (,) includes an initiator (,) having a casing (,) containing a charge of pyrotechnic material (,). An end wall (,) of the casing (,) has score lines (,) delineating petal shaped sections (,) of the end wall (,). The petal shaped sections (,) of the end wall (,) are configured to diverge by deflecting pivotally upon rupturing of the end wall (,) along the score lines (,) under the influence of the pyrotechnic material (,). The apparatus (,) further includes a petal retainer structure (,) having a retainer surface (,). The retainer surface (,) is configured to receive the petal shaped sections (,) of the end wall (,) so as to limit pivotal deflection of the petal shaped sections (,) to amounts less than 90 degrees. The petal retainer structure (,) is thus configured to inhibit fragmentation of the end wall (,) that might otherwise occur upon greater pivotal deflection of the petal shaped sections (,).
