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. The new detent position is ensured by tightening the bolt so that the spring presses the teeth into the tooth recesses.
