Description

Window support for dynamic lamination glazing The present invention relates to laminated glazing, and in particular to laminated glazing intended to be used as dynamic glazing, more specifically to dynamic glazing in which a window support is fixed. The present invention is intended to be used primarily for the manufacture of glazing for automobiles, but is not limited thereto. The present invention relates to glazing equipped with electrical devices requiring electrical connections, examples of which include antennas, functional films for controlling the transparency of the glazing, or displays. For example, in the construction field, such glazing equipped with functional films is dynamic glazing that can be darkened freely, particularly electronically, to prevent solar heat and glare. In the construction field, smart windows can be darkened freely to prevent light from entering the interior in sunny weather, or can be brightened again in cloudy weather to maximize light entry or (if the dynamic glazing includes an integrated display) to maximize light from the display. Additionally, in the construction field, glazing is generally flat or has low curvature. Furthermore, designers and automotive manufacturers are increasingly demanding that functional films, such as switchable films, be provided on side or rear windows to control the amount of light entering the vehicle for temperature comfort and/or privacy and sound insulation comfort. In the automotive sector, such glazing is used, for example, for vehicle roofs, windshields, rear windows, and side windows (including quarter lights). In particular, these vehicle glazing also include window supports as mounting brackets or support frames. These window supports are primarily used for mechanical and structural purposes, such as maintaining, attaching, securing, or connecting the glazing. These window supports are widely used, particularly for sliding side windows of vehicles, where the sliding mechanism is connected to the window support. Furthermore, frame-type window supports are also widely used for fixed glazing in automobiles. Furthermore, automotive designers intend to use at least one of the automotive glazing as a display. Therefore, it is desirable to integrate a display into the glazing, particularly laminated glazing. However, laminating a display into the glazing is difficult due to the characteristics of the functional film. In addition, the display may be combined with a switchable film to maintain temperature comfort and/or privacy protection while increasing contrast. Automotive glazing, such as roofs, windshields, backlights, quarter lights, and sidelights, is typically folded to fit the vehicle's design. The folded shapes become increasingly complex, and the curvature values also increase. The folded shapes are generally obtained by applying pressure and/or heat to the laminated glazing. The folding process is well known to those skilled in the art for folding automotive and/or architectural laminated glazing. In the prior art, the use of liquid crystal (LC) films in glazing has been considered as a method to provide controllable visual blocking. In such applications, the primary function is to convert an inherently transparent glazing into a translucent glazing. Such applications do not include specific embodiments designed to provide electrical connections in the glazing. In particular, it becomes increasingly difficult to provide glazing with robust electrical connections because, specifically during manufacturing and/or use, vibration, shock, significant temperature changes, or tensile forces are applied to automotive glazing on these electrical connections, and in the case of sliding windows, movement is applied to these glazing. WO2022218953 discloses a curved laminated glazing, which comprises a functional film and an optically transparent adhesive for filling the space between the functional film and the glazing. The mechanical structure of such glazing is described. US10858875 describes a connector that surrounds the edge of the glazing, and a window support is aligned with the connector to provide a rigid electrical connection to an electrical device. US7123202 describes a cap on a glazing surface for protecting the connector of an electrical device. EP2801689 is also known that a connector is integrated on the edge of a glazing, a window support is provided with a corresponding socket, and a connector fitted on the edge of the glazing providing the connector is attached to the corresponding socket. In conventional processes, electrical devices are equipped with their own connectors, which are attached to the glazing, for example, by lamination, with one end of the connector suspended or extended from the glazing. Subsequently, during the process of installing the glazing on a vehicle or building frame, the free end of the connector is plugged in to energize the electrical device. Unfortunately, during the installation process, t
