Abstract

An adjustment mechanism is disclosed that includes a housing that has a sidewall extending circumferentially around a central axis defining an opening. A first aperture extends through the sidewall perpendicular to the central axis and a receiving member rotatably coupled to the housing and includes a protrusion that extends along the central axis and an aperture spaced from the central axis. A cable has a first end that extends through the first aperture of the housing and is fixedly coupled to the receiving member and a second end fixed relative to the housing. A knob is rotatably coupled to the housing and is configured to engage the receiving member such that rotation of the knob causes the receiving member to rotate. A locking element engages with the sidewall of the housing, and is configured to disengage the sidewall in response to a manual rotation of the knob by a user.
