Electrically heatable automobile window power-supply connector assembly
First Claim
1. An electrically heatable window of a motor vehicle having resistance heating strips extending over at least part of the window area, a bus bar electrically connecting the resistance heating strips to each other, a contact on the window associated with the resistance heating strips, and a counter-contact on the motor vehicle body which is connected to an electrical power source such as the motor vehicle battery, contact and counter-contact being constructed as push contacts such that in the assembled or closed position of the window, the contact and counter-contact engage each other with additional spring pressure, closing the electrical circuit between the resistance heating strips and the power source characterized in that,the contact on the window consists of the bus bar itself and the counter-contact on the motor vehicle body is disposed on a flange like edge which serves as a support surface for the window in the assembled or closed position and comprises a compression spring-loaded pin which extends perpendicularly or essentially perpendicularly to the window surface and which is movable in the direction perpendicularly or essentially perpendicularly of the window surface, said spring loaded pin being connected at its rear end to a power cable connected to an electrical power source and operatively connected to the bus bar at its front end surface.

Abstract
An electrically heatable fixed rear window of a motor vehicle has resistance heating strips extending over part of the window area and a bus bar which electrically connects the resistance heating strips to each other and provides a contact on the window which cooperates with, and a counter-contact on the motor vehicle body which is connected to an electrical power source such as the motor vehicle battery.
The counter-contact on the motor vehicle body comprises a compression spring-loaded pin which moves in the direction perpendicularly of the window surface, which is connected at its rear end to a power cable connected to the electrical power source and which is operatively connected to the bus bar at its front end surface.
