An apparatus and method are provided for sealing locking components of a retractor, wherein the retractor has a spool shaft extending therefrom. A base of a housing defines an opening therethrough, and an outer surface of the base is mounted to the retractor with the spool shaft extending into the opening. The locking components are arranged on an inner surface of the base of the housing. A sealing member engages the base of the housing and extends about a periphery of about the opening, and also extends about and engages a periphery of the spool shaft, to form a seal between the spool shaft and the base of the housing to block ingress of moisture and particles to the locking components. A cover is hermetically attached to the housing about a periphery thereof with the locking components sealed between the cover and the base of the housing.
