SUMMARY OF THE INVENTION
An object of the present invention is a folding top which is movable from an opened position in which the folded top is stored within the trunk of a vehicle to a loading position in which the folded top is raised to a loading position above the trunk while the trunk lid is opened to thereby provide access to a luggage compartment of the trunk with precautions taken to prevent unintentional closing of the trunk lid against the folded top while the folded top is in the loading position.
Another object of the present invention is a vehicle having the folding top.
In carrying out the above objects and other objects, the present invention provides a vehicle having a folding top (“roof”). The vehicle includes a trunk having a luggage compartment. A trunk lid is movably connected to the vehicle body to move between a closed lid position in which the trunk lid covers the trunk and an opened lid position in which the trunk lid exposes the trunk to provide access therein. The roof has a plurality of roof parts including a rear roof part. The roof is movable between a closed roof position in which the roof parts cover the vehicle interior and an opened roof position in which the roof parts are folded together and stored within the trunk over the luggage compartment. When the trunk lid is in the opened lid position the roof is movable from the opened roof position to a loading roof position in which the roof parts are folded together and raised over the trunk to provide access to the luggage compartment. A blocking device cooperates with the trunk lid to prevent the trunk lid from unintentionally closing against the roof parts when the trunk lid is in the opened lid position while the roof is in the loading roof position.
Further, in carrying out the above objects and other objects, the present invention provides a method for a folding top (“roof”) of a vehicle. The method includes moving a roof having a plurality of roof parts into an opened roof position in which the roof parts are folded together and stored within a trunk of a vehicle. The method further includes moving a trunk lid to an opened lid position to enable the roof to be raised out from the trunk. The method further includes actuating an actuating switch connected to a drive system to actuate the drive system for moving the roof from the opened roof position to a loading roof position in which the roof parts are folded together and raised over the trunk. The method further includes disabling the drive system from moving the roof upon the roof being moved into the loading roof position. The step of disabling includes a support member on one of the roof parts actuating a limit switch connected to the drive system upon the roof being in the loading roof position to de-actuate the drive system. The method further includes blocking the trunk lid from moving toward the trunk while the trunk lid is in the opened lid position and the roof is in the loading roof position. The step of blocking includes the trunk lid and a blocking device cooperating with one another to prevent the trunk lid from moving while the trunk lid is in the opened lid position and the roof is in the loading roof position.
Also, in carrying out the above objects and other objects, the present invention provides a folding roof top for a vehicle. The vehicle includes a trunk having a luggage compartment. The vehicle further includes a trunk lid movably connected to the vehicle body to move between a closed lid position in which the trunk lid covers the trunk and an opened lid position in which the trunk lid exposes the trunk to provide access therein.
The folding roof top includes a roof having a plurality of roof parts including a rear roof part. The roof is movable between a closed roof position in which the roof parts cover the vehicle interior and an opened roof position in which the roof parts are folded together and stored within the trunk over the luggage compartment. When the trunk lid is in the opened lid position the roof is movable from the opened roof position to a loading roof position in which the roof parts are folded together and raised over the trunk to provide access to the luggage compartment. The folding roof top further includes a blocking device. The blocking device cooperates with the trunk lid to prevent the trunk lid from unintentionally closing against the roof parts when the trunk lid is in the opened lid position while the roof is in the loading roof position.
In accordance with embodiments of the present invention, the blocking device reliably prevents the trunk lid from closing when the roof is in the loading position to prevent damage to the trunk lid or the roof. The blocking device is arranged between the trunk lid and the roof. The blocking device includes first and second support members. The first support member is attached to the trunk lid and the second support member is attached to a roof part of the roof. While the roof is in either of its opened or loading positions, the outer side of the rear roof part of the roof faces the roadway of the vehicle and the inner side of the rear roof part faces the top side of the vehicle. The second support member is provided on at least one lateral longitudinal section of the inner side of the rear roof part. Proper cooperation of the second support member with the first support member is achieved as the second support member includes an elastic component formed by a sealing body of the rear roof part. The blocking device and a limit switch may be structurally combined for simplification. For this purpose, the blocking device and the limit switch may be combined into a module so that a vehicle may have a single module.
The above features, and other features and advantages of the present invention as readily apparent from the following detailed descriptions thereof when taken in connection with the accompanying drawings.

Roof parts 6, 7, and 8 are articulately connected to one another to move together between a closed position Sst of roof 5 in which roof parts 6, 7, and 8 cover the vehicle interior and an opened position Sta of roof 5 in which roof parts 6, 7, and 8 are folded on top of one another and lowered into trunk 4 for storage therein thereby exposing the vehicle interior. The solid lines of roof parts 6, 7, and 8 in FIGS. 1 and 2 illustrate roof 5 in its opened position Sta whereas the dotted lines of roof parts 6, 7, and 8 in FIGS. 1 and 2 illustrate roof 5 in its closed position Sst.
Each roof part 6, 7, and 8 includes an inner side and an outer side which are bounded on each end by respective lateral longitudinal sections. Lateral longitudinal sections 10 and 11 of rear roof part 8 each include a sealing body 12. Sealing bodies 12 seal with adjacent body parts such as side windows 13 of vehicle 1 when roof 5 is in its closed position Sst.
In its opened position Sta, roof 5 is stored within trunk 4. Roof parts 6, 7, and 8 are folded on top of one another in a stack and the folded roof part stack is positioned above luggage compartment 9 within trunk 4. Front roof part 6 is situated above middle roof part 7 in such a way that inner side Is1 of front roof part 6 and inner side Is2 of rear roof part 7 face downward toward roadway Fb. Rear roof part 8 assumes a position in which outer side As of rear roof part 8 faces downward toward roadway Fb while inner side Is3 of rear roof part 8 faces upward toward top side Fo of vehicle 1.
As shown in FIG. 3, trunk 4 is located behind rear roof part 8, as viewed in the direction of forward vehicle travel A, when roof 5 is in its closed position Sst. A trunk lid 14 spans trunk 4. Trunk lid 14 is movable between a closed position Vst (shown in FIG. 3) in which trunk lid 14 covers trunk 4 and an opened position Ost (shown in FIGS. 1, 2, and 4) in which trunk lid 14 provides access to trunk 4. Trunk lid 14 is articulately connected to vehicle body 3 to move between its closed and opened positions via a pair of hinges 15 located on each side of vehicle body 3. Trunk lid 14 may be manually swivelled between its closed position Vst and its opened position Ost.
As shown in FIG. 3, vehicle 1 includes a drive device 17. Drive device 17 is operable for moving the stacked roof parts 6, 7, and 8 from the opened roof position Sta to a loading position Bst of roof 5 (shown in FIGS. 2 and 4). Drive device 17 includes an electric motor and/or a hydraulic element which is connected to at least one of the roof parts such as rear roof part 8 for moving roof 5 from its opened position Sta to its loading position Bst. In the loading position Bst of roof 5, stacked roof parts 6, 7, and 8 are raised above trunk 4 to enable access to luggage compartment 9. As indicated above, stacked roof parts 6, 7, and 8 are positioned above luggage compartment 9 within trunk 4 when roof 5 is in its opened position Sta.
An actuating switch 16 is connected to drive device 17 to control the operation of drive device 17. Drive device 17 moves roof parts 6, 7, and 8 from the opened roof position Sta to the loading position Bst of roof 5 upon an operator actuating actuating switch 16. Actuating switch 16 is attached to a horizontal cross-member 18 of an end wall 19 of vehicle body 3. Actuating switch 16 is not accessible to an operator until trunk lid 14 is opened.
A blocking device 20 functions to fix trunk lid 14 in position when trunk lid 14 is in its opened position Ost and roof 4 is in its loading position Bst. Blocking device 20 fixes trunk lid 14 in this position so as to prevent damage to any of roof parts 6, 7, and 8 of roof 5 caused by unintentionally closing trunk lid 14 while roof 5 is in its loading position Bst.
Blocking device 20 is situated between trunk lid 14 and roof 5. Blocking device 20 includes a first support member 21 and a second support member 22. First support member 21 is on hinge 15 of trunk lid 14. Second support member 22 is on one of the roof parts such as rear roof part 8. For this purpose, lateral longitudinal section 10 of rear roof part 8 includes second support member 22. Second support member 22 is an elastic component formed by sealing body 12 which is present on rear roof part 8.
First support member 21 includes a support surface 23 facing second support member 22. Support surface 23 of first support member 21 includes relatively large, inter-spaced support surface sections 24 and 25. Support surface sections 24, 25 in the opened position Ost of trunk lid 14 and the loading position Bst of roof 5 are brought into contact with sealing body 12 of rear roof part 8. That is, support surface sections 24, 25 are brought into contact with second support member 22 when trunk lid 14 is in its opened position Ost and roof 5 is in its loading position Bst. In this position, motion of trunk lid 14 from its opened position Ost to its closed position Vst is counteracted.
Blocking device 20 is structurally combined with an electrical limit switch 26. Limit switch 26 is actuated by second support member 22, i.e., by sealing body 12, to stop drive device 17 after roof 5 has reached its loading position Bst. Limit switch 26 is a lifting switch which includes a contact element 27. Second support member 22 actuates contact element 27 while trunk lid 14 is in its opened position Ost or while roof 5 is in its loading position Bst.
The following operation sequence is employed to move roof 5 from its opened position Sta into its loading position Bst. Trunk lid 14 is moved into its opened position Ost. Trunk lid 14 maybe moved manually into its opened position Ost. Actuating switch 16 is actuated to actuate drive device 17. Upon being actuated, drive device 17 lifts the stacked roof parts 6, 7, and 8 of roof 5 from trunk 4 until second support member 22 actuates limit switch 26. Second support member 22 actuates limit switch 26 when roof 5 has reached its loading position Bst. In response to second support member 22 actuating limit switch 26, drive device 17 is de-actuated to stop lifting roof 5 from its loading position Bst. In the loading position Bst of roof 5, blocking device 20 is active to fix trunk lid 14 in place with respect to any closing motions.
