A housing member for an actuator assembly for adjusting the orientation of
a mirror element in a mirror assembly provides integral weather seals and
noise dampeners. The weather seals and noise dampeners are injection
molded with or onto a base wall of the housing member to thereby form
seals and dampeners that have superior adhesion or mechanical retention to
the housing member and, therefore, are not subject to degradation from
noise. In addition, the integral seals and dampeners reduce the time and
cost of assembling and servicing the actuator assembly. The housing member
includes a base wall, and a sidewall which connects to the base wall and
extends around the perimeter of the base wall. The side wall includes
connectors for securing the first housing to the second housing. A gasket
material is injection molded around the passage to thereby seal the
passage, which forms an annular lip on the inner surface of the base wall
and extends through the base wall to form a flexible diaphragm on the
outer surface of the base wall. The flexible diaphragm includes a first
opening molded around the passage and a second opening for receiving and
sealingly engaging a positioning member, wherein the second opening moves
in and out of the passage with the positioning member when the positioning
member extends out or withdraws into the actuator.
