Description

e e S c ii 1 f 1 b u n g Enclosed car bodies (e.g. coupés) in open (e.g.

Roadster) is, in addition to the foldable convertible tops, known to break down the upper body into several rigid lines, the articulated or displaceable with one another, all or individual Parts of the closed roof structure in the case of an open vehicle in the lower body respectively lowered the trunk; but that is not possible if there is room for that Lowered rear window group already through other vehicle parts such as rear wheel wing, Axle drive, mid-engine, etc. is used. Other types where E.g. the middle upper body part is designed as a roll bar, require that the roof shell must be removed by hand and stowed in the trunk. Apart from that that loose parts are easily lost or damaged, it is with today's Traffic pollution of the streets for reasons of accident prevention not acceptable that in the case of a sudden onset of road that also has a visual impairment, vehicles Stop in the flow of traffic and people only to close the convertible top on the lane have to walk around.

These serious disadvantages are avoided by the inventive Avoided design that all parts of the closed roof structure when Open on the rear body of the car body together, creating a manufacturing process and advantages in terms of handling that are important because there are no loose parts are, the lower body space is not used, as well as opening and closing the structure can also be made from the driver's seat while driving.

The following figures show exemplary embodiments: Fig. I Side view of the roof structure with a wide roll bar Fig. II Section through the lowered roof ball according to Fig. I Fig. III Side view of the roof structure with Roll-over case Fig. IV Section through the lowered roof structure according to Fig. II T) he The roll bar (1) is a fixed part of the Larostierie body (2), like Fig.I shows. The roof shell (3) reads on the front of the windshield frame (4) and on the back of the roll bar (1). At its rear end (5) it is articulated connected to the rear window part (o) that in turn is below (7) on the body (2) is articulated 0 When the roof shell (3) is pushed back, the rear window part lies down in position (6 ') on the rear body (8) and is up through the lowered roof shell (3 ') covered, the rear window (6) can accordingly the upper body shape (8) be arched forward, so that there is a low overall height "h" results (Fig.II) Instead of the rear window part (6) a rear-open one can be used Frame or contact bracket (9) at the top of the Vach shell (3) and at the bottom in the body (8) be hinged, for example if the rear window itself is in the roll bar (1) is fixed or installed as a crank window (10) further to the front. The lower pivot point (7) Kar; n is expediently coaxial with the hinge of the trunk lid (11) because it is easier to open when the roof shell (, ') is on top will can.

Since the wide side surfaces of the roll bar (1) according to Fig. I, impair the view to the side and back, which is very important when overtaking, it is recommended to use only one pipe bracket (12) as a rollover protection according to Fig0 III and to design the surfaces adjoining it to the rear as side windows (13). These are hinged with their rear edges (14) on the rear window part (6) and can be swiveled inwards against the rear window and with this and the hinged Roof shell (3) can be lowered back onto the body (8). Whose Surface resp. the suitcase-.

cover (11) are shaped so that a harmonious connection to it the roof shell (3 ') is created (Fig. IV). This version is also without a roll bar possible, because the roof shell (3) at the back of the upper hinge (5) of the rear window part (õ) and is carried at the front by the windshield window frame (4).

The side window (13) then strikes with its upper edge (15) the roof shell (3) and t the front edge (16) from the inside against the door window (17).

It is also possible not to use the rear side window (13) !! Rear window part (6) to be connected, but as individual parts in-cie body side walls lower so that the rear window part (6) is hinged to it at the top Place the roof shell (3) backwards on the body (8).

The operation of the roof structure takes place in a very simple this from Driver's seat off. A handle is expediently located on the inside of the roof shell (3) appropriate. After loosening the usual tension locks on the windbreak frame (4) leaves move the front part of the roof backwards by hand, thereby removing the rear part of the roof automatically through the rear window (6) respectively. the analog bracket (9) on the back of the body (8) is lowered, then the roof shell (3) by means of the appropriate locking mechanism is being held. Conversely, after releasing this lock, the front edge of the roof can be opened by hand by reaching backwards over the shoulder of your in the closed position (3) pulled up and fastened to a protective frame (4).

These processes can be carried out, for example, by torsion springs in the pivot points (5) and / or (7) influenced respectively. be relieved.

The rear window part (6) be = N. the analog bracket (9) can use the lower pivot points (7) down into the body body (8) reaching lever (18) have pneumatic, hydraulic, mechanical or spring forces at the end (19) attack and control the swivel movement.
