Abstract

A rear view mirror for a motor vehicle of the kind having a stationary housing relative to which the reflective element is adjustable to give the required rear view has a housing which is moulded in self-skinning foam plastics. The housing has resilient pillars which bear on the back of the reflective element near its periphery. The pillars extend from the part of the housing behind the reflective element. Vibration of the reflective element is damped by contact with the resilient material of the housing and the reflective element is kept in its adjusted position. This is very useful when the reflective element is adjustable by remote control.

Claims

1. A rear view mirror for a motor vehicle comprising a housing adapted to be secured to the vehicle, a reflective element, an adjustable joint by which the reflective element is mounted in the housing and which enables the reflective element to be adjusted in relation to the housing to alter the rear view, wherein the housing is a moulding of self-skinning foam plastics material and includes resilient projections which are integrally formed in the foam material of the housing and which bear on the back of the reflective element on opposite sides of the adjustable joint and remote from the adjustable joint.

2. A rear view mirror according to claim 1, wherein the housing is cowl-shaped and has a rim extending over the periphery of the reflective element.

3. A rear view mirror according to claim 2 wherein the rim bears at least on opposite edges of the periphery, resiliently gripping the reflective element.

4. A rear view mirror according to claim 3 wherein the interior of the rim where it makes contact with the periphery is of generally part-spherical form centered on the adjustable joint.

5. A rear view mirror according to claim 4 wherein the interior of the rim has a surface formation which assists in relaxing the reflective element in adjustment.

6. A rear view mirror for a motor vehicle comprising a housing adapted to be secured to the vehicle, a reflective element, an adjustable joint by which the reflective element is mounted in the housing and which enables the reflective element to be adjusted in relation to the housing to alter the rear view, wherein the housing is a mounding of self-skinning foam plastics material comprises pillars and of resilient foam material extending from the housing behind the reflective element and arranged in at least one pair, the pillars of which are symmetrically disposed on opposite sides of the adjustable joint.

7. A rear view mirror according to claim 6 wherein the pillars are of columnar form.

8. A rear view mirror according to claim 6 wherein the pillars are of elongated cross-section and parallel to one another.
