Abstract
An arrangement for controlling solar heating of passenger cars comprises a covering material which is glued onto parts which are subjected directly to the radiation of the sun in the vehicle interior, and a switching device. The covering layer is composed of a foil with a controllable capacity to transmit light, a reflecting layer and a carrier material. When the engine is switched off during parking, the foil will transmit light, whereby the incident light is reflected on the reflecting layer. In the driving operation of the passenger car, the foil will be dull, impervious to light and absorbs the incident light.
Claims6
An arrangement for controlling radiant heating of interior vehicle parts exposed to solar radiation comprising:
- a carrier material;
- a reflecting layer disposed on said carrier material;
- and
- a foil layer having a controllable light transmitting capacity, which foil layer is disposed on said reflecting layer;
- and
- a control unit which controls said foil layer to be in a light transmitting state when an engine of said vehicle is switched off, whereby incident light is transmitted to and reflected by said reflecting layer, and to be in a light absorbing state when said engine is switched on.
