Abstract: A ventilation device for the inside of a motor vehicle, having at least one air outflow element and at least one associated directional element. The at least one air outflow element is provided in a functional arrangement with an air channel element. The air channel element represents the connection to a supply device as part of an air conditioning system. At least one light element is also provided. The arrangement of the at least one directional element and the at least one air outflow element work together so that the ventilation device can be continuously adjusted at least between two inside ventilation conditions. The at least two ventilation conditions respectively differ at least by means of a direction of outflowing air directed directly into the inside and directed indirectly along a roof liner designed for this reason in relation to a seat region of the motor vehicle.

Abstract: A heating system for a windshield of a vehicle, in which a fan unit is configured to produce a hot air flow at the inner side of the windshield. In order to enable efficient heating of a windshield of an electric vehicle, there is provision for the heating system to have an at least predominantly transparent partition unit, which in a shielding position is secured in the vehicle in such a manner that it is arranged in the longitudinal vehicle direction between at least a predominant portion of the windshield and an inner region which is provided for passengers, whereby the hot air flow can be guided at least partially in a heating region between the windshield and the partition unit.

Abstract: An air-conditioning duct for vehicles with one duct mutually connected and fixed to the other duct is provided. One duct is formed by incorporating a first unit duct with a flange formed around an opening periphery thereof and a second unit duct with a flange formed around an opening periphery thereof in parallel. The other duct is formed by incorporating a third unit duct with a flange formed around an opening periphery thereof and a fourth unit duct with a flange formed around an opening periphery thereof in parallel. The flange formed on the boundary side of the second unit duct are fixed with one over another, and the flange formed on the boundary side of the third unit duct and the flange formed on the boundary side of the fourth unit duct are fixed with one over another.

Abstract: A structure for connecting an air-conditioning duct to an air-conditioning unit; the air-conditioning unit 1 having a first air supply outlet 11 and a second air supply outlet 12 adjacent with each other, the air-conditioning duct having a first air passage and a second air passage adjacent with each other, wherein the first air supply outlet 11 and the second air supply outlet 12 include a U-shaped auxiliary wall 2 having a notched part K at one side therearound, a supply outlet boundary wall 130 separating the first air supply outlet 11 and the second air supply outlet 12, and a duct side step part Z is formed between an opening rim of a first duct 31 and an opening rim of a second duct 32, the duct side step part Z is contacted with is contacted with the supply outlet boundary wall 130 to install the air-conditioning duct 2 to the air-conditioning unit 1.

Abstract: A unidirectional valve for venting moisture from a window having at least two panes or lights, the panes or lights defining an air space therebetween, is provided. The valve includes: an elongated body having an interior passage formed lengthwise therein, wherein at least a portion of the elongated body is adapted to be inserted directly through a window pane and into the air space formed between the panes; at least one resilient plate pivotally connected to the elongated body; wherein the resilient plate moves in response to changes in fluid pressure within the air space formed between the panes of the window, and wherein the movement of the plate opens the interior passage for allowing moisture-laden air to pass therethrough and out of the air space or closes the interior passage for preventing air from flowing back into the air space between the panes.

Abstract: A vitreous system of the invention is provided for use particularly as windowpanes of a car or the like vehicle, and is always kept clean over its whole surface. A multi-layer vitreous body ‘A’ forming the system is composed of an outside glass plate (1), an inside glass plate (2) and a stratified air space (3) defined between the inside and outside plates. A number of jetting orifices (1a) are formed to penetrate the outside plate (1), and a compressor (5) is connected through a piping (4) to the air space (3) so as to charge it with a compressed air, so that this air is blown out through the orifices (1a).

Abstract: A windshield device for obtaining a favorable screen effect with respect to an air flow from the sides of a screen while suppressing large-sizing of the screen in the vehicle width direction. In a front cowling which includes a screen unit which is mounted on a front portion of a vehicle body and has a screen, an air introducing opening is formed in a front portion of the screen unit and opens forwardly. An air blow-off opening is formed in an upper portion of the screen unit that opens upwardly. An air duct allows the screen unit and the air blow-off opening to communicate with each other. Air discharge ports which open outwardly and to the sides from the vehicle are formed in a side of the air duct.

Abstract: A vehicle window ventilation system of this invention contains vertical slots in forward portions of the window or frame. Air due to vehicle movement passes in the slots to the cavity between the windowpanes. There is a passage for airflow from the cavity rearward to the door handle where there is spacing for outward passage of air. The forward location of the vertical slots allows for the flow of air across a wide area of the windows and hence a minimum reduction of visibility due to moisture in the cavity. The air passageway rearward through the cavity between the windows and then through the door to the rearward located door handle allows for a dispersion pattern of air that covers a large amount of the surface area of the double pane window. While an external fan could be used to enhance the removal of flow of air the forward location of the vertical slots and the rearward location of the inner door passageway to the door handle alleviates the necessity of having a fan.

Abstract: A window system for defrosting the windows of a vehicle comprises a windshield assembly having first and second spaced-apart panes of glass with an interlayer of air space therebetween. A frame surrounds the panes and maintains the air space therebetween. An inlet extends through the bottom wall of the frame for entry of air between the windshield panes. An outlet extends through a side wall of the frame for discharging air from between the windshield panes. The system also includes a plurality of window assemblies, each window assembly including first and second panes with an air space therebetween. An inlet extends through one side of the window frame for entry of air between the window panes. An outlet extends through an opposed side of the window frame for discharge of the air therefrom. The inlets and outlets of the windshield and window assemblies are positioned such that air may freely pass between adjacent assemblies through channels extending through vehicle support posts.
