This invention relates to folding rear view mirrors for vehicles.
With vehicles such as agricultural or industrial tractors the variety of trailers, implements or attachments which may be drawn behind the tractor is very varied and this presents a problem in providing rear view mirrors which can be easily adjusted between the different width settings that are necessary to provide a clear rear view around the different trailers, implements or attachments which may be used.
One option is a telescoping arrangement as described, for example, in U.S. 2003/0117729, but such arrangements are not simple to adjust if not mechanised and may have penalties in terms of cost and component count. Simpler systems based on pivoting links, described in GB 1 339 123 and U.S. Pat. No. 3,031,929, allow a mirror mount to collapse inwards if an obstacle is encountered but do not support adjustment over a wide range of width settings whilst remaining visible to the user.
