Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an upper structure of a motor vehicle, in particular a passenger car.

BACKGROUND OF THE INVENTION A roof construction or superstructure for a motor vehicle, in particular a passenger car, with a rear roof transverse support partially covered by the edge area of a glued-on rear window is known from DE 26 55 990.

Problems to be Solved by the Invention The problem to be solved by the present invention is that the roof panels are arranged in parallel and spaced apart in the traveling direction of the automobile, are connected to each other by the horizontal plates 2c and 3c, and are located almost entirely on the rear end of the roof outer panel 6. two chambers 4, 5 extending laterally across the width;
A superstructure for an automobile comprising: a lateral support 1 having a lateral support 1; a rain door opening upwardly between the two chambers; and a rear glass fixed to the lateral support. , while maintaining good hydrodynamic airflow without obstructing the heads of rear seat passengers, the rear glass (rear window) reliably drains rain that falls on the roof while the vehicle is in motion.
and the rear edge of the roof skin,
The purpose is to prevent this rain from flowing onto the rear windshield while the car is running.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a superstructure of a motor vehicle according to the invention at the rear end of the roof skin, with a transverse support and a transverse plate, which are supported from each other and spaced apart in the direction of travel of the motor vehicle. two chambers arranged in series and extending over substantially the entire length of the lateral support;
a rain gutter opening upwardly between the two chambers; and a rear glass fixed to the lateral support; a front region that has a shape that smoothly extends to cover a part of the rain gutter and the car seat and the seat; and a front region that smoothly extends to the front region and starts at the rear end of the rear seat and gradually descends to the rear end of the rear glass. (b) the rear end portion of the roof outer plate is configured to include a delay ridge located at a distance in front of the rain gutter and extending in the lateral direction of the vehicle; This is achieved by comprising a sloped part extending to the front end of the rain gutter and connected to the rain gutter.

A particularly advantageous structure of the invention is defined in claim 2.
Shown below.

Embodiment The embodiment of the invention shown in FIG. 1 consists of a lower jacket 2 and an upper jacket 3 which are connected to each other by welding or gluing at the end flanges 2a, 3a and 2b, 3b in sheet metal construction. 1 shows the lateral support 1 of the rear roof. The lower sheath 2 and the upper sheath 3 each have a region roughly in the center thereof that is drawn in (constricted) toward the other, and the deepest parts thereof are horizontal plates 2c, 3c that are fixed to each other.
It is formed of. The transverse support 1 is thus divided into two chambers 4, 5 one behind the other in the longitudinal direction of the vehicle. This makes the lateral supports very tall when very short.

The roof skin 6 of the vehicle terminates in a bent flange 7 which rests on and is fixed to the transverse panel 3c. The roof skin 6 has a retardation ridge 8 for rainwater flowing away, just before transitioning to a slope 8a, which forms a double-bent end region and gradually descends in the direction opposite to the direction of travel of the vehicle.

Towards the rear of the vehicle, its contour is interrupted by a rear glass 9. The glass 9 covers the chamber 5 of the transverse support 1 and has a free canopy over a part of the rain gutter 10 made above the transverse plates 2c, 3c. This canopy ensures that rainwater is not sucked upwards out of the rain gutter 10 even under unfavorable circumstances.

The rear glass 9 is attached to the upper envelope 3 of the transverse support 1 by adhesive 11, and its lower area covering the rain gutter 10 and the chamber 5 is colored 12, preferably by silk screen printing.

A ridge protector 13 is attached to the free upper edge of the rear glass 9. The edge protector 13 also performs a water guiding function.

The lower side of the lateral support 1 is completely covered with a roof covering 14. The back of the head of the rear seat passenger is indicated by the chain line 15.
As shown, it is located in front of the lateral support 1 and is not obstructed by this.

The front area 9a of the rear glass 9, except for the inclined part 8a and the rain gutter 10, is smoothly connected to the extended surface of the upper surface of the roof skin 6, and the rear area 9b of the rear glass 9 is 16. Although the curvature changes at the position indicated by , it still continues smoothly with the front region 9a.

The operation of the upper structure of the automobile having the above structure will be described.

While the car is running, rain that falls on the roof outer panel 6 runs backwards on this, reaches the delay ridge 8 and its speed is weakened, and flows into the rain gutter 10 through the slope 8a and is drained. Ru. In this way, since the flow velocity of rainwater is weakened by the delay ridge 8, the rainwater does not flow over the rain gutter 10 to the rear glass 9, and it is possible to avoid worsening the rear visibility of the driver's vehicle.

In addition to the advantages already mentioned, the inventive arrangement reduces the effectiveness of solar radiation protection for rear seat passengers, reduces the force flux of the lateral support of the roof-rear column-floor frame, considerably saves weight, and improves the manufacturing efficiency. This has the advantage of simplifying the process.

The embodiment of the invention of FIG. 2 is essentially the same as that described above and therefore the same reference numerals are used. The difference is
It is only that the cross plates 2c, 3c are spaced apart from each other and that the cross plate 2c has a hole 2d for passing a spot welding electrode, for example.

This embodiment is clearly advantageous when welding three plates is difficult due to wide differences in the thickness of the plates.

In the embodiment of FIG. 3, the same reference numerals are used for the parts already described. The difference is the lateral support 22
The structure is as follows. The support 22 consists of two tubes 1 of rectangular cross section creating separate chambers 19, 20.
7 and 18, which are connected to each other by a U-shaped or Z-shaped horizontal plate 21. tube 17,1
8 is manufactured as an extruded or drawn part.
The flange 7 of the roof outer panel 6 is fixed to the intermediate horizontal plate 21a of the horizontal plate 21.

As described above, in the automobile superstructure of the present invention, since the rear end of the roof outer plate is provided with a delayed ridge and a sloped part that continues to the rain gutter, the roof outer plate and the rear glass surface are While maintaining good hydrodynamic properties of flowing air, it is possible to prevent rain that falls on the roof from flowing into the rain gutter and onto the rear glass while the car is running. effective.
