Abstract
A method of making an electrically heated window from at least two plies of transparent glazing material, at least one ply of interlayer material and an electrically resistant heating area device extending over one of the plies includes laying at least one length of busbar strip on one of the plies to form part of a busbar, positioning a separate corner piece of busbar strip adjacent the length of busbar strip to form a corner of the busbar, and electrically connecting the corner piece and the length of busbar strip to one another. An electrical connection device is arranged to extend from the electrically resistant area heating device past the peripheral edge of the window to terminate outside the window. The plies of glazing material are then laminated together with the ply of interlayer material and the electrically resistant area heating device extending between them. The corner piece and the length of busbar strip can be electrically connected together by providing one of the conductive strip surfaces with a coating of low melting point solder so that upon autoclaving all of the layers to form the laminated window, the solder melts and provides the electrical connection.
