Description: An open roof construction for a vehicle, as well as a vehicle fitted with such an open roof construction The present invention relates to an open roof construction for a vehicle in accordance with the preamble of claim 1. Such an open roof construction is disclosed in International patent application WO 01/14158. With this known construction, a folding roof is moved to a position on the rear window of a vehicle as a unit, after which the rear window can be swung back into the boot . The object of the invention is to provide an open roof construction which is arranged in such a manner as to enable a reliable transition of the closure element from the operative position to the rearwardly moved storage position. In order to accomplish that objective, an open roof . construction according to the invention is characterized in that the cover plate is mounted on cover plate slides capable of sliding movement in the guide rails, which each comprise a height adjusting mechanism to be actuated by an adjacent rear slide of the closure element, which functions to move the cover plate upwards before further movement of said unit is possible. This construction of the cover plate enables the cover plate to provide a seal in the operative position of the closure element, which seal is broken by moving the cover plate upwards, in which position the cover plate is released for being moved to the rear. The upward movement of the cover plate can also be utilized for unlocking the cover plate so as to enable said rearward movement. Advantageous embodiments of the invention constitute the subject matter of the dependent claims. The invention leads to a very compact operating mechanism near the cover plate, in which a number of parts have more than one function. The invention will now be explained in more detail with reference to the drawings, which show an exemplary embodiment of the open roof construction according to the invention. Fig. 1 is a side elevational view of one of the guide rails of the open roof construction, with the cover plate and one slide of the folding roof present therein. Figs. 2 - 7 are larger-scale views of a part of the guide rail, in which the rear side of the folding roof, the cover plate and the slide are shown in various positions thereof, which illustrate the transition of the folding roof from a folded position to a rearwardly moved storage position. The present invention is intended especially, but not exclusively, for use in an open roof construction for a vehicle as shown in Dutch patent application no. 1016578, whose contents are incorporated herein by reference thereto. In this embodiment, the open roof construction comprises a folding roof, which is conventionally provided with stationary guide rails on either side of a roof opening formed in the roof of the vehicle. One of said guide rails is indicated by numeral 1 in the drawing. The folding roof furthermore includes a flexible liner (not shown) and a drivable operating beam at the front side of the liner, which operating beam is guided in guide rails 1 for selectively opening and closing the roof opening. A number of folding elements is provided for supporting the liner and defining a folding movement thereof when the folding roof is being opened. These parts of the folding roof do not form part of the invention, and consequently they are not shown in more detail. The folding elements are mounted on slides which are guided in the guide rails 1. Of said slides, a rear slide 2 is shown in the drawing. The rear side of the folding roof, or the rear side of the roof opening formed by opening the liner, is defined by a cover plate 3, which is fixed to the rear side of the liner and which provides a seal against the fixed roof at the rear side of the folding roof. The operating beam, the slides 2 and the cover plate 3 of the folding roof can be interlocked to form one unit in an entirely open position of the folding roof, which unit can subsequently be moved to a position on a rear window 4 of the vehicle. The rear window 4 is likewise provided with guide rails 5, which are aligned with the guide rails 1 of the vehicle. The operation and the construction of this rear window is described and illustrated in great detail in the aforementioned patent application and will not be discussed in detail herein, therefore. The cover plate 3 must remain stationary during the normal operation of the folding roof and provide a seal at the rear side of the folding roof, but it needs to be lifted from the sealing position and be unlocked in order to enable its movement to the rear window 4, which can be realised by means of the present invention. Fig. 2 shows the parts of the cover plate 3 and the slide 2 on a larger scale. As the figure shows, the cover plate 3 is provided with a link plate 6 at the location of the guide rail 1, which link plate includes a pivot pin 7 with a guide cam 8 near its rear side, by means of which the link plate 6 is pivotally mounted on a cover plate slide 9. The guide cam 8 is a tight fit in a guide hole 10, which is inclined at a slightly larger angle than the guide cam 8, thus defining the maximum pivoting angle of the link plate 6. A slot 11 is formed near the front side of the cover plate slide 9, which slot opens to the front, where it is formed with a locating funnel 12; a slot portion 11' extends parallel to guide rail 1 behind said funnel, which slot portion 11' continues into an downwardly and rearwardly sloping slot portion 11' ' . Said slot 11 is capable of cooperating with a lateral (coupling) cam 13 on the adjacent slide 2 of the folding roof. The cam 13 and the slot 11 jointly form a height adjusting mechanism for the cover plate 3. The lateral cam 13 is present on a support which is in the form of a rearwardly extending pin 14, which can engage in a supporting slot 15 in the cover plate slide 9, which extends parallel to the guide rail 1. In the position of the folding roof in which the folding roof parts are interlocked to form one unit, the pin 14 is accommodated in the supporting slot 15 in its entirety, so that any forces that may be exerted on the cam 13 , and thus on the pin 14, can be adequately absorbed. The figure furthermore shows that a locking cam 6 is present on the underside of the link plate 6 of the cover plate 3, which cam is spaced from the pivot pin 7 by some distance, as a result of which it will move along in vertical direction with the cover plate upon pivoting of the link plate 6. In the lower, locked position of the cover plate 3, the locking cam 16 is in engagement with a locking recess 17 as a counter element for the locking element in the form of a locking cam 16 of the link plate 6. The cover plate 3 is locked in position in the longitudinal direction of the guide rail 1 as a result of the locking cam 16 engaging in the locking recess 17. The underside of the locking cam 16 is slightly inclined, in such a manner that, in the upwardly pivoted position of the cover plate 3 , the underside of the locking cam 16 extends at least substantially parallel to the guide rails 1, 5, resting on the bottom of said guide rail 5, as a result of which the locking cam 16 locks the respective link plate 6 in the upwardly pivoted position, thus preventing downward pivoting movement thereof. Thus it is ensured, in combination with the engagement of the cam 13 in the slot 11, that the cover plate and the rear slide 2 are interlocked to form a unit in rearwardly moved positions. Since said rear slide 2 is also interlocked with preceding slides and with the operating beam, said parts are all interlocked to form one unit in rearwardly moved positions . As is furthermore shown in the figure, the cover plate slide 9 includes a locking element 18 comprising a hook 19 that can hook behind a mating shoulder 20 on the link plate 6 in the downwardly pivoted, locked position of said link plate 6. The locking element 18 comprising the hook 19 is pivotable about a transverse extending pivot 21 on the cover plate slide 9. An engaging cam 22 is present on locking element 18 includes for actuation thereof, with which an actuating cam 23 on the rearwardly extending pin 14 of the adjacent slide 2 can make contact for pivoting the locking element 18 from a position in which it locks the link plate 6 in position to a position in which it releases the link plate. The engaging cam 22, and thus the locking element 18, is spring-loaded by a biasing spring 24 on the cover plate slide 9, which biases the locking element 18 to the position in which it locks the link plate 6 and thus the cover plate 3 in position. The operation of the embodiment of the open roof construction according to the invention will now be described with reference to Figs . 2 - 7. Fig. 2 shows the folding roof in an almost entirely open position. In this position, the cover plate 3 is locked in position at the transition between the guide rail 1 and the guide rail 5. The rear slide 2 nears the cover plate 3. The cover plate 3 is locked in position with respect to the guide rail 1 as a result of the engagement of the locking cam 16 in the locking recess 17. The hook 19 of the locking element 18 engages round the shoulder 20 of the link plate 6 of the cover plate 3, so that the cover plate 3 is locked in the sealing position. In Fig. 3, the rear slide 2 has been moved so far to the rear that the rear portion of the pin 14 of the slide has entered the supporting slot 15 and the lateral coupling cam 13 on said pin 14 has arrived at the beginning of the slot 11. Fig. 4 shows the position in which the actuating cam 23 on the pin 14 of the slide 2 has come into engagement with the engaging cam 22 of the locking element 18 and has pivoted the locking element 18 about the traverse pivot 21, as a result of which the hook 19 has moved out of engagement with the shoulder 20. Now the link plate 6 of the cover plate 3 is released for pivoting movement about pivot pin 7. In the position that is shown in Fig. 5, said pivoting movement has started, and that as a result of the movement of the coupling cam 13 in the sloping slot portion 11' ' of the slot 11. The only way in which the coupling pin 13 , which is not movable in vertical direction, can move into said sloping slot portion 11 ' is through a pivoting movement of the link plate 6. In Fig. 6, the link plate 6 has been pivoted so far upwards by the movement of the cam 13 in the slot 11 that the locking cam 16 has moved out of the locking recess 17, as a result of which cover plate 3 is no longer locked in position in guide rail 1. The cover plate 3 can now follow the rearward movement of the slide 2, as has already happened in Fig. 6. The locking cam 16 has moved above the bottom of the guide rail 1/5 and engages said guide rail, as a result of which the link plate 6 can no longer pivot downwards and the link plate 6 is thus locked against pivoting movement in this upper position. Accordingly, also slide 2 and cover plate 3 are locked in position, as a result of the engagement of the coupling cam 13 in the slot portion 11 ' ' of the slot 11. After all, the cam 13 can only move through slot 11 as a result of the pivoting movement of the link plate 6. In Fig. 7, the unit consisting of cover plate 6 and slide 2 has been moved rearwards to a position on the rear window 4, so that the unit is present in the guide rail 5 of the rear window. In this way, the entire folding roof unit can be moved to a position on the rear window 4. The return movement of the cover plate 3 takes place in a comparable, reverse manner. Also the locking of the cover plate 3 with respect to the guide rail 1 and the uncoupling of the slide 2 takes place in the reverse manner. The locking element 18 with the hook is forced back into the locked position again by the biasing spring 2 . From the foregoing it will be apparent that the invention provides a compact and reliable construction, which ensures that the cover plate 3 is correctly locked and unlocked and moved from and to the sealing position. The invention is not restricted to the use thereof with a olding roof . The principle of the invention can not only be used with a folding roof, but also with other roof types, such as a spoiler roof, a sliding roof, a slatted roof or a similar roof comprising a closure element other than a foldable liner.
