Sealed locking retractor

摘要

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.

1. An apparatus for sealing locking components of a retractor, wherein the locking components cooperate with a spool shaft extending from a rotatable spool of the retractor to selectively lock rotation of the spool, and wherein the spool shaft rotates with the rotatable spool, the apparatus comprising:
a housing including a base defining a first opening therethrough, the base of the housing having an outer surface mounted to the retractor with one end of the spool shaft extending into the first opening, the locking components arranged on an inner surface of the base of the housing opposite the outer surface thereof, a first sealing member engaging the base of the housing and extending about a periphery of the first opening, the first sealing member also extending about and engaging a periphery of the spool shaft, the first sealing member blocking ingress of moisture and particles from the outer surface of the base of the housing to the inner surface of the base of the housing, and a cover hermetically attached to the housing about a periphery thereof with the locking components sealed between the cover and the base of the housing.
