A laminated safety glass windscreen, which can also be used as a reflector in a HUD system, comprises at least first and second panes and a thermoplastic intermediate layer which joins these panes together. The cross-section of the intermediate layer is in the shape of a wedge, decreasing in thickness from top to bottom. The thermoplastic intermediate layer may be composed of two sheets, one of which is provided with a colored filtering strip and has a wedged cross-section conditioned by the appearance of this filtering strip. The other sheet has a wedged cross-section such that the two sheets together have the prescribed convergence angle for using the windscreen as a reflector.

A window with an aerial for motor vehicles is provided with an electrically conductive layer (,) which fulfils the function of an aerial conductor. In order to prevent capacitive coupling of the layer to the bodywork of the vehicle, the layer (,) ends at a distance of a few centimetres from the edge of the window. The layer (,) is coupled capacitively to the aerial connection cable leading to the receiver set by means of a coupling electrode (,). The coupling electrode comprises thin wires (,) which are connected together by electroplating and are arranged at a large distance from one another which is large compared with their diameter.

In a contact device for an electrical functional element, for example an antenna, disposed on a window, in particular on a vehicle window, with a housing fixed on the window and comprising electrical components, such as an amplifier, with an input connection between the housing and the functional element, which is also fixed on the window, and with output links in accordance with the invention, the input connection (,) is, in two different variants, each time surrounded by an adhesive layer, independently of its placement in electrical contact; in one of the variants, it is disposed outside the housing (,), in the other variant it is overlain by the housing (,). The electrical contact to the functional element is effected during or after bonding the housing and respectively the input connection, preferably by soldering, so as to ensure particularly reliable placement in contact.

A window pane antenna suitable for radio communication, for automobiles, consists of a loop-shaped antenna conductor (,) and of a conductive area (,) disposed in the edge zone of the glass pane (,). The feed point (,) of the antenna conductor (,) is disposed in the immediate vicinity of the conductive area (,) without connection to it. The other end (,) of the antenna conductor (,) is in electrically conducting connection with the conductive area (,). In comparison with known antenna structures for radio communication, the tuning behavior of this antenna structure is comparative insensitive to mechanical tolerances during installation of the antenna window pane.

An automobile windshield covered with a transparent electrically conducting layer, on which some hollowed spaces are provided in the form of slots. The length of these slots is a function of the wavelength of the microwave radiation. The microwave radiation, as used for transmission of information in portable telephone sets or remote surveillance systems of toll roads, for example, is absorbed by the conducting layer to again be retransmitted by the slots which act as antennas. In this manner, vehicle windshields which are provided with an electrically conducting layer which reflects the infrared can allow microwave radiation to pass through.

A diversity reception antenna window provided with connection elements has connection lands of several antenna elements as well as shielding or grounding lines clustered at a location lying in the border area of the window locally in proximity to each other. Components (26) provided with connection plugs (40, 41), which at their base end have a flat support comprising junction lands (29, 33, 35, 31, 37, 39), which are arranged in accordance with the same layout as the corresponding connection lands on the window, are used as connection elements. The joining by soldering of the junction lands of the connection element with the connection lands on the window is performed in a single operation.

A glazing for an enclosed space includes at least one sheet of glass having a precisely delimited surface region and a transmitter and/or a receiver for electromagnetic radiation in a non-visible portion of the spectrum. The transmitter and/or receiver are positioned for respectively transmitting and receiving radiation in a non-visible portion of the spectrum via the precisely delimited surface region. The transmissivity of said precisely delimited surface region for electromagnetic radiation in said non-visible portion of the spectrum is higher than that of a remainder of the at least one sheet of glass for electromagnetic radiation in the non-visible portion of the spectrum.

An electrically heated composite glass sheet including heating element wires deposited and fixed in place on the thermoplastic film connecting the individual glass sheets together so as to extend from the one film edge as far as the opposite film edge. The heating wires are connected in parallel with buses, which are arranged at a predetermined distance from the edge of the film. Directly adjacent to the buses, the sections of the wires which are arranged between the buses and the edge of the film are severed by moving two electrodes, which are connected with a power supply, into contact with the wires. The electric current heats the wires between the electrodes to their fusion temperature and thereby severs the wires.

For the electric connection of a transparent surface layer (2), serving in particular as a heating resistor, on a glazing or glass substrate (1), it is proposed to deposit a coating (4) of a brazing having a low melting point by utilizing a soldering or brazing machine subjected to an ultrasonic vibration. A connecting metal electrode (5) can be soldered in spots (6) or over its entire surface to the surface layer thus solidly coated. As a result, the performance of the connectors in the finished product is improved.

A windshield (1) for motor vehicles provided with a reflecting arrangement (6) for making optical information or signals visible to the driver of the vehicle; said information or signals being made recognizable in the same field of view as is suitable for the observation of traffic and the road ahead by said driver. According to the invention, the reflecting arrangement (6) is a hologram with the characteristic of a mirror. The angle of reflection .alpha. of the holographic mirror is different from the angle of reflection .beta. of the surface of the glass upon which said hologram is mounted. As a result the rays R' reflected from the surface of the glass do not reach the eye (8) of the observer, whereas the rays R reflected from the holographic mirror do. In the case of a bent windshield, a hologram with the function of a flat mirror will be disposed on a carrier layer curved corresponding to the shape of the windshield so that even in the case of bent windshields, the reflected image of the optical signals or information is free of aberrations.

A reasonably priced power supply circuit for a motor vehicle with two different load voltages, viz. the normal vehicle supply system voltage and a voltage higher than this for operation of a window heating glazing with a thin-film heating resistor. A generator is designed for the higher voltage, which corresponds at least to the voltage required for operation of the window heating glazing. With the window heating glazing switched off, the voltage supplied by the generator is adjusted to the vehicle supply system voltage by a controller. With the window heating glazing switched on, the vehicle supply system voltage is derived from the higher voltage. To ensure a safe operating condition, a time switch for the temporary reduction of the exciter current for the generator during change-over of the load switch, a main timer for limitation of the heating time and a threshold voltage switch for limitation of the generator voltage are provided as additional monitoring elements.

Apparatus for an electrically moved sliding window used in automotive applications, having a built-in safety device is described. This detector is a proximity detector which detects the approach of a portion of a human body, e.g. a gloved hand. This detector is advantageously comprised of a capacitive pickup carried along the upper edges of the window, connected to a detector stage which, as a function of the rate of change in the signal appearing across the pickup, acts, via an amplifier, to remove the electrical power supplied to the drive motor of the window.
