Temperature indicator for motor vehicle
First Claim
1. A rear view mirror including a transparent reflective member having front and rear surfaces and a reflective layer on said rear surface for reflecting images that are viewable through said front surface, and a temperature indicator of thermochromic material between said rear surface and said reflective layer, said thermochromic material changing to different colors at different temperatures.

Abstract
A temperature indicator for a motor vehicle arranged to indicate, to the driver of the vehicle, the ambient temperature either inside or outside the vehicle. The temperature indicator comprises thermochromic material (36-46) applied to the reflective member (30) of a rear view mirror (10) and arranged in a line, locations along which are arranged to change colour at successively increasing temperatures. The line of thermochromic material (36-46) may be positioned to separate zones (32, 34) of the reflective member which differ in curvature.

- 1. A rear view mirror including a transparent reflective member having front and rear surfaces and a reflective layer on said rear surface for reflecting images that are viewable through said front surface, and a temperature indicator of thermochromic material between said rear surface and said reflective layer, said thermochromic material changing to different colors at different temperatures.
- 6. A rear view mirror including a transparent reflective member having front and rear surfaces, said rear surface having a rear surface area, a temperature indicator of thermochromic material applied to and covering a small portion of said rear surface area and being viewable through said reflective member from said front surface thereof, said thermochromic material changing to different colors at different temperatures, and a reflective layer on the remainder of said rear surface area that is not covered by said temperature indicator for reflecting images that are viewable from said front surface.
- 30. An exterior rear view mirror for a motor vehicle operable by a driver, the mirror being positionable on a motor vehicle for the viewing of images therein by a driver of the vehicle, said mirror including a reflective member that reflects images that are viewable by a vehicle driver, said reflective member having a main zone with a first curvature and an auxiliary zone of greater curvature than said first curvature, said reflective member having a temperature indicator of thermochromic material thereon that is visible to a driver of the vehicle, said thermochromic material being arranged in a line that includes a plurality of locations that sequentially change color at increasing temperatures, and said thermochromic material being positioned to provide a line of demarcation between said main zone and said auxiliary zone.
