Abstract

A vehicle exterior mirror has a cowl 2 which is spaced at its forward edge from the edge of the mirror to define a slot 4. The slot extends around the entire circumference of the mirror. Apertures 5 at the rear of the cowl communicate with the slot 4. In use of the vehicle, air passes into the apertures and out through the slot, and this air stream tends to carry spray away from the surface of the mirror. Hitherto, fouling of the mirror occured due to a reduced pressure region created in front of the mirror in use. <IMAGE>

Description

SPECIFICATION Vehicle exterior mirror This invention relates to vehicle exterior mirrors.
A problem for drivers of vehicles, especially commercial vehicles, is the fouling of the mirror which occurs in bad weather conditions due to spray from the roadwheels being drawn into the region of reduced pressure created in front of the mirror in use.
The invention provides a vehicle exterior mirror having a cowl arranged behind the mirror, the forward edge of the cowl being spaced from the edge of the mirror to define a slot between the cowl and the mirror extending around the circumference of the mirror, and having one or more apertures in the cowl communicating with the slot.
In use of the vehicle, air passes into the aperture or apertures and out through the slot and this air stream tends to carry spray away from the surface of the mirror.
An exterior rear-view mirror for a commercial vehicle will now be described by way of example, with reference to the accompanying drawings, in which: Figure 1 is a vertical section through the mirror; Figure 2 is a perspective view of the front of the mirror; and Figure 3 is a perspective view of the rear of the mirror.
Referring to the drawings, the mirror comprises a mirror head 1 mounted via a friction clutch (not shown) in a cowl 2 which is firmly supported on a mirror arm 3. The edges of the mirror head are spaced from the forward edge of the cowl to define a slot 4 there between, which allows for adjustment of the alignment of the mirror head relative to the cowl. The shape of the cowl 2 is chosen so as to reduce aerodynamic drag.
A series of apertures 5 are provided in the rear of the cowl, and these communicate with the slot 4. When the vehicle is moving, air passes through the apertures 5 and fast moving jets of air are thus directed around the edge of the mirror head. These jets of air protect the mirror surface by carrying fouled water away.
The width of the slot 4 is approximately 5mm.
The aperture may be located anywhere suitable in the cowl.
1. A vehicle exterior mirror having a cowl arranged behind the mirror, the forward edge of the cowl being spaced from the edge of the mirror to define a slot between the cowl and the mirror extending around the circumference of the mirror, and having one or more apertures in the cowl and communicating with the slot.
2. A vehicle exterior mirror as claimed in claim 1, wherein the apertures are in the rear of the cowl.
3. A vehicle exterior mirror substantially as hereinbefore described with reference to and as shown in the accompanying drawing.
