<p>An exterior mirror for a vehicle comprises a base member adapted to be mounted on the vehicle body, first pivotal engagement means mounted on an arm secured to the base member so as to project laterally from the vehicle body, a housing for a reflective member having second pivotal engagement means, and resilient means for urging the first and second pivotal engagement means into engagement with one another so that the housing is pivotally movable relative to the base member about a first pivot axis. First abutment means on the housing and second abutment means on the base member closer to the vehicle body than the first pivot axis are so arranged that that movement of the end of the housing remote from the base member in a predetermined direction causes angular movement about the first pivot axis, bringing the first abutment means into engagement with the second abutment means, continued movement of the end of the housing remote from the base member in said predetermined direction causing angular movement of the housing about a second pivot axis coincident with the point of engagement of said abutment means and resulting in mutual disengagement of the first and second pivotal engagement means. The resilient means is coupled to said point on the base member by a link which is pivotally attached to the base member at said point, the link being movable between a first position in which the line of action of the spring pulls the housing towards its position of normal use and a second position in which the spring pulls the housing towards the body of the vehicle.</p> |
