Abstract

A motor vehicle has an openable roof which can be raised and swiveled back via pairs of swivel arms that engage laterally in its end area until it is placed on the rear compartment, possibly with a little distance. In the opposite way, the roof can also be closed again and sealed and secured in the front edge area. This makes it possible to use a vehicle with a rigid roof both as a convertible and as a correspondingly safe limousine without additional frame structures or the like being necessary, and without losing additional storage space in the rear compartment for the openable roof.

Description

The invention relates to a pivoting vehicle roof, in particular for passenger cars, which can be placed on the rear rear area after opening and at the transition to the area of the rear window as well as joints or the like at the transition from the rear window to the area of the rear area and attack swivel arms on both sides in the rear end area, which are also approximately at the level of the hinged to the lower edge of the side and rear windows and can be pivoted together.

Such a pivotable vehicle roof is known from DE-OS 19 45 559. It becomes a rigid one Allows vehicle roof, which can be placed on the rear compartment when opened, and on each side of the The roof is provided with a swivel arm, the lower swivel joint on the vehicle itself and the one upper swivel joint engages the roof in each case. that this performs an undesirable relative pivoting movement and, for example, by the airstream is folded up. When closing the roof it is also necessary that this has a horizontal

In this way, the for

The solution to this problem is that at the opening of the rigid roof a serving structure At least two roll bars are integrated on one side of the roof, when the roof is closed extending pivot arms are provided, the roof performs its function while it is open and that this roof, which can be moved together with one another, does not act as a disruptive element in the then ge swivel arms are profiled and the profiles protrude at least the desired free space, if also for the open on the rear space stored position at least th state a roll bar is desired partially interlock. Advantageous further developments of this easily within the clear cross-sections of the subject matter of the invention are provided separately from the dependent claims of the closed roof, to be found. It can be particularly advantageous if the lower

This allows the with the help of the swivel arm extending swivel arms substantially parallel to 45 formed roll bars also in the lower area even move and pivot and be closed, resulting in further bracing in the rear compartment. This also enables a '"

Actuation while driving because the roof area practically only with its narrow side is directed against the wind and remains directed. Especially in In the position stored on the rear compartment, the swivel arms, due to their profiling, partially interlocks, occupying as little space as possible, while at the same time providing good stiffening and stabilization this swivel arm is achieved.

It is particularly advantageous if at least two pivot arms are arranged on both sides of the vehicle roof are that the roof with the vehicle body, especially immediately behind the passenger compartment,

Below is an embodiment of the invention with its essential details described in more detail with reference to the drawing. It shows

F i g. 1 is a side view of a vehicle with the roof closed,

F i g. 2 shows a side view according to FIG. 1 with the roof opening or closing, with three intermediate positions of the roof are shown,

F i g. 3 shows a side view of a vehicle with the vehicle completely open and thereby deposited on the rear compartment Roof part,

4 shows the rear view of a vehicle with the closed Roof and

F i g. 5 shows the rear view of a vehicle with an open roof and

F i g. 6 the top view of the vehicle with the roof open,

F i g. 7 to 10 in view, in two cross-sections and in Top view of a preferred embodiment of the pivot arms holding the roof.

A motor vehicle designated as a whole by 1 has a rigid, but nevertheless pivotable and openable one Vehicle roof 2, which according to FIGS. 2 and 3 can be placed on the rear compartment 3, and in the following is called roof 2 for short

In the rear lateral end area of the roof 2, two side by side grip each other on both sides Pivot arms 4 articulated, which also on the vehicle body 5 approximately at the level of the lower edge the side windows 6 are attached to joints 7 and can be pivoted together. Especially in Fig. 2 recognizes one that the roof 2 can be raised and pivoted by pivoting the pivot arms 4 back, wherein the roof surface remains essentially parallel to itself. If the roof 2 is initially shown in FIG. 1 closed, it can be swiveled backwards and placed on the rear compartment 3. From this open position according to FIG. 3 it can then in the opposite way by pivoting the pivot arms 4 back into the Closing position according to FIG. 1 can be brought. Special Fühnmgskonstruktionen above the stern area and special precautions that despite such constructions allow the rear space 3 to be opened are avoided.

One can see above all in FIG. 2 that the length the pivot arms 4 are approximately the distance of their joint 7 on the vehicle body 5 from the rear edge area 8 of the rear space 3 corresponds. in order to be able to store a correspondingly large roof area, as shown in FIG. 3 is shown

F i g. 2 also shows that the pivot arms 4 are each arranged approximately parallel to one another, resulting in a good guidance of the roof 2 leads even during the opening and closing movement.

One recognizes in FIG. 2 and 3 as well as in FIG. 6 also that the body-side joints 7 of the Swivel arms 4 are arranged close to the hinges of the trunk lid, so that an opening of the The rear area may even be possible with the roof 2 lying on it. However, it is possible to open the Rear compartment 3 just as well possible that roof 2 in an ίο at least partially raised position again bring.

In the F i g. 2, 4 and 6 can be seen an advantageous embodiment of the invention, in which a rear window 9 holding frame 10 is provided, the lower and upper edge area of which is articulated to the body or the vehicle body 5 or the roof 2 are attached, so that this rear window 9 when open and closing of the roof can be folded down at the same time; F i g. 2 shows that the outside of the The rear window is placed against the top of the rear space 3, so that contamination of the interior of the Vehicle is also avoided in the area of the rear window. The inside of the Roof on the inside facing surface of the rear window in the closed position, so that also here none Transferring pollution, rather preventing pollution during driving.

In Fig. 1 it can be seen that the roof 2 opposite the rear window 9 has an upper stand 11 at open roof can serve as a spacer with respect to the rear space 3. This supernatant can take off Sealing rubber od. Like. Padding material exist, so that the paint of the trunk lid when open Roof is protected.

Especially in Fig. 6 it can be seen that the pivot arms 4 of the two sides of the vehicle each with one another are connected so that they simultaneously form 1 roll bar for the closed vehicle. The corresponding Cross bars are shown in FIG. 6 marked with number 12

The FIG. 6 also that 4 cross bars 13 are provided in the lower region of the pivot arms can be, so that an even better stiffening of this construction and the roll bar formed thereby results

The drive of the pivoting movement for opening and closing the roof can be done by hand and / or with the help one or more servomotors take place, so that especially in the latter case this opening and Closing movement can advantageously also take place while driving. It can be seen in FIG. 2 It is clear that this is also possible because the main roof surface is also in the intermediate positions is exposed to practically no wind

Overall, the result is due to the laterally engaging pivot arm pairs in the rear roof area the possibility of a stiff roof 2 of a vehicle 1 without additional frame guides or the like. On the To be able to store the rear compartment so that the vehicle can be opened and used as a convertible while it has the desired rigid roof 2 in the closed position. The rear window 9 be made of glass so that the glass pane contributes to further stiffening The parallel guide or almost par-

allelic guidance of the roof 2 during the opening and closing movement allows this movement to be carried out even with at least a reduced driving speed.

Control drives for opening and closing the vehicle via a speedometer, so that operation is prevented when the vehicle speed is too high.

In the F i g. 7 to 10 is highlighted and separately a particularly favorable embodiment of the Swivel arms, which carry the roof 2 and are suitable for placing it on the rear space 3, are shown. This special embodiment avoids cuffs or the like. Fabric parts in this side area and results Nevertheless, a good stiffening and, in a particularly advantageous way, the possibility with the roof closed to vent the interior of the vehicle.

Especially when comparing FIGS. 8,9 and 10 recognizes that the rigid roof 2 which can be stored on the rear space 3 and which can be moved together with one another Swivel arms 4 are profiled and the profiles are at least in the stored position on the rear space 3 according to FIGS. 8 and 9 at least partially intermesh and fit into each other and when in the closed position of the roof 2 according to Fi g. 7 overlap laterally with at least one leg 24. The F i g. 8 and 9 show cross-sections through the pivot arms 4 brought into the open position at different Positions shown in FIG. 7 are marked with the lines IX-IX on the one hand and X-X.

The cross-sections according to FIGS. 8 and 9 illustrate that as pivot arms 4 in the embodiment U-profiles are provided, although under certain circumstances angle profiles could also be sufficient. These When the roof 2 is put down or open, U-profiles interlock and complement each other with at least a U-leg 24 according to Fi g. 7 with the roof 2 closed laterally approximately to form a continuous surface. In practice, the outer U-legs 24 of the profiles forming the swivel arms 4 form when the arm is closed Roof a body part, as is the case with rigid, self-supporting bodies between the rear and side windows are provided below the roof surface.

In the exemplary embodiment there are a total of three U-profiles with pivot bearings or joints lying next to one another 7 are provided, which run approximately parallel to one another and on three pivot bearings lying next to one another 25 on the side of the rear area of the roof 2. One can clearly see that each front joint 7 on the vehicle corresponds to a front pivot bearing 25 on the roof 2

The U-profiles of the swivel arms 4 are oriented in this exemplary embodiment in such a way that the free edges of the U-legs 24 and 26 extend backwards in the direction of travel or, when the roof is open, downwards towards the rear space 3. This is particularly clear from FIG. 8 and 9. When the roof is closed, the U-profiles simultaneously form gutters that run obliquely from top to bottom. It is useful if these U-shaped swivel arms 4, with their cross section essentially opening upward, open with a closed roof 2 (FIG. 7) over a body cavity or the like with a water drain. This gives these swivel arms and their profile an additional function, because they are not only very stiff and well suited to holding the roof during the opening and closing process, but also effectively prevent rainwater from entering the passenger compartment when the roof is closed. It is nevertheless possible that the overlapping areas of the swivel arms 4 have some play and, when the roof 2 is closed, serve as interior ventilation. The access of water is nevertheless prevented by the three U-shaped pivot arms 4 lying one behind the other in the manner of a backdrop and their labyrinth-like interlocking, while air can nevertheless escape.
7 to 9, it becomes clear that at least the innermost U-profile in its interior contains a seal 27 which projects beyond the U-legs 24 and supports the swivel frame and the roof 2 with respect to the rear space 3. This seal cushions the roof when it is placed on the rear compartment, prevents damage to the surfaces and also provides a seal against rainwater when the roof is closed. It can also be seen that the rear window or the rear window 9 is connected to this narrowest, rearmost when the roof 2 is closed and the lowest when the roof 2 is open, and laterally in the area of its U-leg 26 facing the vehicle center and preferably in the one enclosed therein Seal 27 protrudes so that it also seals this rear window 9 as well.

At least the uppermost swivel arm 4 in the open position carries a U transverse web 28 on the outside a seal 29 effective in the closed position of the roof 2 with respect to the side window 6. In FIG. 8 is true the position shown with the roof open, but the interaction of the side window 6 with the seal 29 indicated how it occurs with the roof closed.

First of all, F i g. 10 makes it clear that the U-shaped Swivel arms 4 each taper towards their joints or bearings 7 and 25 and are arranged at an angle are to go from a larger vehicle width in the area of the vehicle-side joints 7 to a smaller one Transfer width in the roof area and in the area of the pivot bearing 25. This applies to numerous vehicle types The existing smaller width in the roof area can therefore be achieved through the interlocking and approximately parallel to bridge mutually movable swivel arms in a simple manner, advantageously in this position the roof edge reaches over a large part of these swivel arms, which is also due to the comparison 8 and 9 with FIG. 10 becomes clear. It So there is a safe and wide support of the roof 2 on the widest, topmost in the open position Swivel arm 4, which has the already mentioned seal 29, which in turn now also has the roof 2 itself opposite the swivel arm 4 cushions and cushions.

The roof-side bearing bolts on the pivot bearings 25 can be designed as rods that the Connect swivel arms on one side with those on the other side, as shown in FIG. 10 recognizes thereby there are, in turn, the aforementioned rollbars, when the roof 2 is closed.

The U-transverse webs 28 of the U-shaped pivot arms 4 are in the area of the vehicle-side joints 7 or Pivot bearing 25 beveled, which can be seen especially in FIG. 7 recognizes. Opposite the course of the U-profiles these bearing-side end pieces of the U-transverse webs 28 themselves close an obtuse angle accordingly the angle of these profiles relative to a horizontal with the roof closed. One recognizes in 7 that these somewhat angled areas of the profiles run approximately horizontally when the roof is closed. As a result, these swivel arms adapt well to the body shape and the location of the roof as well as the Slope of the rear window 9. Nevertheless, they are also well and safely stiffened and in the area of the joints 7 can according to FIG. 10 one inside the other.

In FIGS. 8 and 9 it can be seen that the respectively outer U-legs 24 are longer in cross section than the inner U-legs 26 and have enough space for the in particular on the outer U-legs 24 engaging or the inner U-legs 26 of the above Pivot arm 4 crossing vehicle-side bearing bolts release, also as a continuous Rods can be designed to a total of a stable frame with the swivel arms and the to form the aforementioned cross members 12.

Especially when combining the aforementioned features and measures and especially when using of mutually fitting profiles as swivel arms, the side profile legs of which are closed when the Supplementing the roof to form a body surface results in a motor vehicle 1 in which the Roof 2 can also be opened and closed while driving, but no volume when open of the passenger compartment and / or the trunk as it is smooth and streamlined on the Trunk or rear space 3 can be placed. In the closed state, and from itself a good rainproofness, but still a desired ventilation of the passenger compartment allows. If desired, in the overlapping areas of the side profile parts of the Swivel arms sealing lips can be arranged over all or part of the length of this Swivel arms are sufficient and thus reduce the ventilation or - if desired - eliminate it.
