Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is constructed as a device with various air outlets, mounted on the inside of the door, in which the air outlet on the door side connects to the side glass leading to the windshield and the interior of the vehicle associated with this part. Concerning air delivery, heating and ventilation systems for automobiles.

Such a device is known from DE 2636640. Here, on the inner door panel close to the window, a shaped hollow body is provided with a longitudinally distributed glass and an air outlet directed towards the inner door panel. The ductwork reduces the cabin width, especially at shoulder height. It becomes difficult to get on and off the vehicle. Since the conduits are relatively long, the warm air required to keep the side windows fog-free in cold weather has only a small amount of energy. As a result, the side windows that receive warm air cannot be sufficiently fogged, and the driver is particularly troubled by incomplete visibility.

The object of the present invention is to provide a heating and ventilation system which allows air to flow into the interior of the vehicle in the vicinity of the windows without reducing the width of the interior of the vehicle and at least provides the area of the side glass necessary to maintain sufficient visibility for the driver. It is to manufacture the device.

The heating of a motor vehicle is therefore configured as a device with various air outlets mounted on the inside of the door, in which the air outlet on the door side delivers air to the side glass leading to the windshield and the interior of the vehicle associated with this part. According to the invention, the airflow outlet for supplying air into the vehicle interior is provided at the transition between the instrument panel and the inner door panel, is connected to the conduit above, and is connected to the side glass of the conduit. The sides extending parallel to the side surface constitute the at least triangular, inward side side of the blind reduced to the window section, and at least one side face in the side wall adjoining the side glass of the conduit is formed.
There are two air outlets through which the compressed air flow is directed towards the nearby side glass section.

A high fog-free area can be obtained if the duct reaches the top of the window frame and has several air outlets directed towards the side glass.

By constructing the door-side side wall of the upwardly ascending conduit from the associated window frame, an appropriate conduit size can be obtained. By drawing a conduit from the air distribution space adjacent to the conduit and passing the air through the inner door panel and into the interior of the vehicle, passenger comfort is improved.

When attaching an outside rear view mirror to a part of a car window that is not covered by glass, attach the base (feet) of the mirror to the outside side of the conduit, and direct the air overflowing from the conduit to the back side of the mirror's reflective glass. It is advantageous if the light is rotated and finally released into the outside world through the gap between the reflective glass of the mirror and the frame of the mirror.

When the conduit passes through the part where the outer rearview mirror can be controlled remotely, conduit or rod operation can be easily performed.

Two embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a heating and ventilation system 2 connected to the front door 1 is organically installed on the inner door panel 3, and also at the transition to the instrument panel (not shown) and above the inner door panel 3. . When the door is closed, the air distribution space 4 inside the heating and ventilation system 2 is connected to the pipe system 5 and selectively supplied with warm or fresh air by means of an operating device (not shown) that is easily accessible to the driver. It can lead you to the exit.

From the air distribution space 4, the air flow reaches the passenger compartment via an outlet 6, where the direction of the air can be changed by means of a regulating device (not shown). The air distribution space 4 is directed upward to the conduit 8 . The inner side surface 10 extending parallel to the side glass 9 of the conduit constitutes the side surface 11 of the interior space of the triangular blind; the outer side surface, which is not visible in the figure, is provided with an outer rear sight 12.

In the wall 13 adjacent to the side glass 9 of the conduit 8 there is an air outlet 14 through which, if necessary, the heated air exits in the shortest possible way and blows onto the area near the side glass 9. This ensures a free view of the direction of the outer rear endoscope 12 and the traffic on this side from the driver.

Further, from the air distribution space 4 to the inner door panel 3
A conduit 15 extends underneath, so that fresh or temperature-conditioned air can be conveyed into the passenger compartment 7 from the inner door panel 3 through which the air passes. moreover,
The air distribution space 4 is connected to the space on the back side of the reflective glass 17 of the outer rearview mirror 12 through the hole 16, so the heated air goes around the back side of the reflective glass 17 and exits the mirror frame 19 through the gap 18. I can get out. If the outer rear view mirror 12 can be controlled remotely, the conduit 8 can be connected to the part 2 of the operating device in a manner not detailed.
Can be chained to 0.

The heating and ventilation device 2 of FIG. 2, again provided at the transition between the inner door panel 3 and the instrument panel 21, has an air distribution space 4 and an outlet 6. A pipe line 8 is connected to the air distribution space 4 . It reaches as far as the upper part 22 of the window frame 23 and its outlet 14 in the wall 13 directs the air to adjacent parts of the side glass 9. In this embodiment, although not shown, the side wall of the conduit 8 on the door side is constituted by the associated window frame 23, so that the conduit 8 itself does not become too large.
