Motor vehicle glazing
First Claim
Patent Images
1. A motor vehicle glazing comprising:
- an external glass sheet and an internal glass sheet joined by one or more thermoplastic interlayer sheets;
at least one electrically supplied functional assembly being inserted between the sheets of the glazing; and
a capacitive sensor controlling supplying of the functional assembly via a unit for processing signals emitted by the sensor, the sensor also being inserted into the glazing on a transparent support coated with a conductive layer which is also transparent, in which layer the sensor is formed,wherein the capacitive sensor comprises two electrodes formed in the conductive layer, signals emanating from each electrode resulting in an analysis by the processing unit, andwherein the electrodes defining the sensor are extended over the support by conductors also formed in the conductive layer, the conductors being at a distance from one another which is of an order of a greatest dimension of a surface covered by the electrodes.

Abstract
A motor vehicle glazing including two sheets of glass, outer and inner, brought together by one or more inserted thermoplastic sheets, at least one electrically powered functional assembly being inserted between the sheets of the glazing, a capacitive sensor controlling power supply of the functional assembly by a unit for processing signals emitted by the sensor, the sensor also being inserted into the glazing on a transparent substrate coated with an equally transparent conductive layer, a layer in which the sensor is formed.

18. A motor vehicle glazing comprising:
-
an external glass sheet and an internal glass sheet joined by one or more thermoplastic interlayer sheets; at least one electrically supplied functional assembly being inserted between the sheets of the glazing; and a capacitive sensor for controlling supplying of the functional assembly, the sensor located on a transparent support coated with a conductive layer which is also transparent, in which layer the sensor is formed, wherein one of the thermoplastic interlayer sheets defines a housing and the transparent support has dimensions so that it fits within the housing, wherein the capacitive sensor comprises two electrodes formed in the conductive layer, signals emanating from each electrode resulting in an analysis by the processing unit, and wherein the electrodes defining the sensor are extended over the support by conductors also formed in the conductive layer, the conductors being at a distance from one another which is of an order of a greatest dimension of a surface covered by the electrodes. - View Dependent Claims (19, 20)
