6. A restraint assembly for releasably restraining an occupant in a vehicle, the restraint assembly comprising:
a first web connector including
a first tongue having a first engagement feature;
a first web receiving portion configured to receive a first web; and
a first tongue cover at least partially covering the first web receiving portion;
a second web connector including
a second tongue having a second engagement feature;
a second web receiving portion configured to receive a second web; and
a second tongue cover at least partially covering the second web receiving portion;
a housing assembly configured to releasably engage the first and second tongues, the housing assembly including
a housing cover, wherein the housing cover at least partially defines an opening that receives at least the first tongue; and
one or more locking features configured to releasably engage at least the first engagement feature; and
an actuator movable relative to the housing assembly, wherein movement of the actuator from a first position toward a second position releases the one or more locking features from the first engagement feature;
wherein each of the first tongue cover and the second tongue cover includes a surface finish having a durometer hardness equal to or less than approximately Shore A 70.
7. The restraint assembly of claim 6 wherein the surface finish comprises a paint.
8. The restraint assembly of claim 7 wherein the paint comprises a urethane paint.
9. A web connector assembly comprising:
a web connector configured to be coupled to a web;
a housing assembly configured to receive at least a portion of the web connector;
a first coating disposed over at least a portion of the housing assembly, wherein the first coating has a first thickness and is elastically compressible to a second thickness that is approximately 90% of the first thickness;
an actuator movable relative to the housing assembly, wherein movement of the actuator releases the web connector from the housing assembly; and
a second coating disposed over at least a portion of the actuator; and
a third coating disposed over at least a portion of the web connector, wherein each of the second and third coatings has the first thickness and is elastically compressible to the second thickness.
10. A web connector assembly comprising:
a web connector configured to be coupled to a web;
a housing assembly configured to receive at least a portion of the web connector;
a first coating disposed over at least a portion of the housing assembly, wherein the first coating has a first thickness and is elastically compressible to a second thickness that is approximately 90% of the first thickness; and
a second coating disposed over at least a portion of the web connector, wherein the second coating is softer than the first coating.
11. The web connector assembly of claim 10 wherein the first coating has a durometer hardness that is equal to or less than approximately Shore A 70.
12. A web connector assembly comprising:
a web connector configured to be coupled to a web;
a housing assembly configured to receive at least a portion of the web connector; and
a coating disposed over at least a portion of the housing assembly, wherein the coating has a first thickness and is elastically compressible to a second thickness that is approximately 90% of the first thickness, wherein the coating comprises a urethane paint, and wherein the urethane paint comprises a resin, a thinner, and a hardener.
13. A method of manufacturing a personal restraint assembly, the method comprising:
forming a web connector having a tongue portion and a web receiving portion;
covering at least a portion of the web receiving portion with a first coating having a durometer hardness equal to or less than approximately Shore A 70;
