Abstract: A mirror mount includes a one-piece molecularly continuous base member and a mirror arm. The mirror arm fastens a mirror to the base member. The base member may also have first and second ends, a side portion, and a reinforcement. The side portion extends between the first and second ends. The first end is generally vertical when the base member is affixed to a fender, and the first end receives a generally horizontal fastener that passes through the first end, through two portions of the fender, and into the base member so as to fasten the base member to the fender. The side portion has a contour that generally follows a profile of the fender. The reinforcement reinforces the first end.

Abstract: A mirror unit for a vehicle includes a base from which extends an arm holding a mirror housing. The arm is pivotably mounted in the base to permit the mirror to be pivoted toward the vehicle in the event that the mirror is struck, for example. The extended position of the mirror when not folded is defined by a detent in the pivoting movement. The detent position of the mirror is the result of a bolt that presses a spring. The spring in turn presses a hub on the arm against an indexing pivot post, so that ramps on the hub bear against ramps on the indexing pivot post and define the detent position of the mirror. The indexing pivot post has an arrangement of teeth that engage into tooth recesses on the base when pressed thereagainst by the spring. The detent position of the mirror can be changed by the user by the user releasing the bolt to relieve spring pressure on the teeth so that the teeth of the indexing pivot post disengage from the tooth recesses and can be pivoted to a new detent position.
