DETAILED DESCRIPTION

(17) FIG. 1 shows the upper part of a vehicle, particularly a passenger car. The vehicle may however also be an SUV, a truck, a camper, caravan, or the like. The vehicle has a fixed roof 1, in this case comprising a very large opening 2, in which the roof system is arranged. In the embodiment shown in FIGS. 1 and 2, the roof system includes an at least semi-transparent first or front stationary panel 3, a movable, central ventilation panel 4 and a second or rear stationary panel 5. The roof system could, however, also comprise one stationary panel only, either the front or the rear, although the front panel 3 would be favoured. The panels 3-5 are made of glass or of plastic and be made permanently semi-transparent or be provided with a (known) system to vary the transparency of one or more of the panels, for example electronically.

(18) The central ventilation panel 4 is in this case quite narrow or short in longitudinal (X) direction, but dimensions could be varied. It would also be possible that there are two separate ventilation panels arranged side-by-side in transverse (Y) direction. In the embodiment shown, the ventilation panel 4 is movable between a closed position substantially flush with stationary panels 3 and 5 and an open position, in which the rear side of ventilation panel 4 is moved upwardly to a rearwardly and upwardly inclined position. Other movements are conceivable as well.

(19) FIGS. 3, 4 and 5 show how the roof system is fixed to longitudinal reinforcement beams 6 of fixed roof 1 of the vehicle. These longitudinal reinforcement beams 6 are also called cantrails. They comprise a horizontal flange 7 onto which a frame 8 of the roof system can rest. Frame 8 is made primarily from plastic, here Polyurethane (PU) but PBT+ASA, SMA, PP and PAG are also available as frame material. A glue bead 9 can be used to attached frame 8 to fixed roof 1.

(20) Especially FIGS. 3 and 4 show that frame 8 comprises a reinforcement 10, preferably made of metal, particularly steel. It extends at least along and below the circumference of ventilation panel 4 and includes a plurality of cross bars 11 leaving a plurality of ventilation openings 12. The reinforcement 10 also extends such that it overlaps flanges 7 of reinforcement beams 6 of fixed roof 1, so that it can be attached thereto, either directly, for example by (spot) welding, or indirectly by means of glue and/or bolts. As is shown in FIG. 4, reinforcement 10 may be covered by the plastic of frame 8 at the position of flanges 7.

(21) FIGS. 3 and 4 show that frame 8 may carry a seal 20 below the whole circumference of movable panel 4. Downwardly extending ribs 13 may be provided at the transverse sides of reinforcement 10. The ventilation panel 4 is preferably adjusted by an electric motor through an operating mechanism (not shown), positioned either in the middle or on one or both transverse ends of panel 4. Panel 4 may also be split inti two panels arranged side-by-side and each having its own operating mechanism.

(22) FIG. 5 shows that plastic frame 8 is also glued by glue bead 9 to flange 7 at the position where no reinforcement is present. Here, plastic frame 8 extends around the whole circumference of panels 3 and 5. In this embodiment, the panels 3 and 5 and frame 8 are first assembled into a unit and during manufacture of the vehicle the unit is built into the vehicle, as illustrated in FIGS. 6A and 6B. It is also shown there that the vehicle may also be provided with a transverse reinforcement beam 14. This will be further discussed with reference to other embodiments.

(23) FIGS. 7A and 7B shows an embodiment in which frame 8 is only present around movable panel 4 and is provided with short longitudinal protrusions 15 only along their longitudinal sides. This small unit will be built into the vehicle first and only then panels 3 and 5 are glued to the front and rear of frame 8 and on the other sides directly to the longitudinal reinforcement beams 6 of fixed roof 1 and to transverse beams.

(24) FIGS. 8A-8C illustrate an embodiment in which frame 8 is provided with two short longitudinal protrusions 15 at the rear only. Long longitudinal protrusions 16 are arranged at the front of frame 8, such that front panel 3 can be glued to frame 8 to form a unit, then built into the vehicle and only then rear panel 5 is glued to frame 8 and directly to the vehicle. As frame 8 in this embodiment also does not extend around the whole circumference of front panel 3, this panel will also be partly glued directly to the vehicle.

(25) In the embodiment of FIGS. 9A-9B, frame 8 has long protrusions 16 in both rearward and forward direction, so that both panels 3 and 5 can be united with frame 8 before the unit is built into the vehicle. Generally, reinforcement 10 will extend into either short protrusions 15 or long protrusions 16.

(26) FIG. 10A10E again show the embodiment of FIGS. 8A-8C as built into the vehicle. FIGS. 10C and 10E show the joint where frame 8 ends and panels 3, 5 are attached directly to flange 7 of fixed roof 1. In FIG. 10C on the right an encapsulation 17 of panel 3 is attached to frame 8 by a glue bead 19. This is already done in the factory of the manufacturer of the roof system. It is further shown in FIG. 10C that frame 8 and encapsulation 17 of panel 3 are attached to flange 7 by glue bead 9. This is done at the manufacturer of the vehicle. To enable this, encapsulation 17 includes a step 18, so that the lower side of frame 8 and the lower side of encapsulation 17 adjacent frame 8 are substantially flush, and together they are attached to flange 7 by glue bead 9. The same configuration is shown in FIG. 10E for rear panel 5.

(27) FIGS. 11, 12 and 13 are cross sections of the embodiment of FIGS. 8A-8C or 9A-9B at the positions of those of FIGS. 3-5. It is shown that in FIG. 11 that encapsulation 17 of panels 3 and 5 carry a seal 21 to seal ventilation panel 4 in its closed position. There is a wet area 22 below seals 21 to catch any water seeping through. In FIG. 12, frame 8 is attached to flange 7, whereas in FIG. 13 encapsulation 17 of panel 3 is attached to frame 8 by glue bead 19, while frame 8 is attached to flange 7 of fixed roof 1 by glue bead 9.

(28) FIGS. 14 and 15 show how panels 3 and 5 are attached to fixed roof 1 at their front at rear sides. Both figures show that panels 3 and 5 are not only attached with their perimeter encapsulation 17 to transverse beams 23, 24, respectively, but also with an additional transverse encapsulation 25, 26 spaced from encapsulation 17 and attached to a horizontal flange 27, 28 at the free edge of transverse beam 23, 24.

(29) FIG. 16 is a cross section through another embodiment in which sunshades 29, 30 are provided, of which a winding roller housing 31, 32 for a winding shaft is arranged below the front and rear edge of ventilation panel 4. In this way the rollo sunshades can be moved to a closed position below the respective panel 3, 5 to prevent light coming through semi-transparent panels 3, 5 from entering the vehicle's interior.

(30) FIGS. 17A and 17B show further variations of the roof system having transverse reinforcement beam 14 as already shown in FIG. 6A. In FIG. 17A, transverse reinforcement beam 14 is part of the roof system and is welded or bolted to reinforcement 10 of frame 8. This transverse reinforcement beam 14 will be glued to longitudinal reinforcement beam 6 of fixed roof 1. In FIG. 17B, transverse reinforcement beam 14 is part of the vehicle and therefore welded or bolted to longitudinal reinforcement beams 6. Frame 8 is glued to transverse beam 14 then.

(31) From the foregoing it will be clear that aspects of the invention provide a versatile roof system having low cost and profile, but still allowing ventilation.
