Abstract
A pivot mechanism for a vehicle external rear view mirror assembly is disclosed. The mechanism includes: a base frame portion and a case frame portion mounted to the base frame portion for rotation about a pivot axis. A detent is operable between the base frame portion and the case frame portion. A spring mechanism clamps the case frame portion to the base frame portion and includes a compression spring disposed around the axis and a spring tie. The spring has first and second tie ends spaced apart from each other and connected by a tie shaft. The tie shaft passes through the spring. The spring tie shaft includes a spring tie reaction feature, whereby in a deployed position, a torque applied to the case frame portion about an axis orthogonal to the axis by an external force is resisted by the spring tie reaction feature.
