Abstract

An exterior mirror for a vehicle comprises a base member attached to the vehicle body, first pivotal engagement means mounted on an arm secured to the base member so as to project laterally in the opposite direction to the mounting face, a housing for a reflective member having second pivotal engagement means. Resilient means extend between a point on the base member which is nearer to the mounting face than the pivot axis and a chain comprising a first link and a second link. The first link is pivotally attached to the base member at one end and pivotally attached to the second link at the other end, the resilient means being pivotally attached to an intermediate point on the second link. A cam surface on the second link is urged by the resilient means into engagement with a projection on the base member located between the pivot axis and the point of connection of the first link to the base member. The projection engages against an abutment at one end of the cam surface when the links are in a position such that the line of action of the spring pulls the housing towards its position of normal use, and engages in a recess at the other end thereof when the orientation of the links is such that the line of action of the spring pulls the housing towards the mounting face, e.g. as a result of impact on the housing.
