The adjustment mechanism includes a housing with a bore formed therein, a clutch positioned within the housing, and a rotatable shaft positioned within the housing and being operatively connected to the first mounting portion. The shaft is configured to rotate within the bore relative to the housing. The shaft is rotatable within the bore in a first rotational direction through the clutch with a first torque, and the shaft is also rotatable within the bore in a second rotational direction through the clutch with a second torque.
