Abstract

A glass roof arrangement, having a support frame fixedly connected to roof structure parts of a vehicle body. At least one transparent roof panel is fixedly arranged on the support frame, and a shading device is assigned to the underside of the roof panel and has a shading structure displaceable longitudinally in guide rails fastened to an underside of the roof panel. A guide profile cross-section of each guide rail is formed from an edge limb supported substantially orthogonally on the underside of the roof panel, and a guide limb extends substantially parallel to the underside and is attached to the edge limb such that a lateral guide channel for the shading structure is formed and delimited by the underside of the roof panel, the edge limb, and the guide limb.

First claim

The invention claimed is:

1. A glass roof arrangement for a motor vehicle, the glass roof arrangement comprising:
a support frame, the support frame having an operating state, the support frame in the operating state being mounted in a manner fixed on the motor vehicle by being fixedly connected to roof structure parts of a vehicle body of the motor vehicle;
at least one transparent roof panel fixedly arranged on the support frame and having an underside;
a shading device, disposed at the underside of the at least one transparent roof panel and having a shading structure; and
guide rails fastened to the underside of the at least one transparent roof panel, the shading structure being displaceable longitudinally in and relative to the guide rails in a displacement direction, each guide rail having a guide profile cross-section, the shading structure having a pair of edge regions spaced-apart from one another in a direction transverse to the displacement direction, the shading structure being guided laterally in each of the guide profile cross-sections, each guide profile cross-section being formed by an edge limb oriented substantially orthogonally to the underside of the at least one transparent roof panel, and a guide limb extending substantially parallel to the underside of the at least one transparent roof panel and being attached to the edge limb, such that a lateral guide channel for the shading structure is formed and delimited by the underside of the at least one transparent roof panel, the edge limb, and the guide limb, the edge regions of the shading structure being slidably engaged within the respective lateral guide channels.

2. The glass roof arrangement according to claim 1 , wherein each guide rail has an adhesive limb projecting from the edge limb in a direction opposite from a projection of the guide limb, the adhesive limb being positioned at a distance from the underside of the at least one transparent roof panel.

3. The glass roof arrangement according to claim 2 , wherein the adhesive limb is positioned at a distance from the underside of the at least one transparent roof panel such that a gap is formed between the adhesive limb and the underside of the at least one transparent roof panel, the gap accommodating an adhesive bead.

4. The glass roof arrangement according to claim 3 , wherein the distance of the adhesive limb from the underside of the at least one transparent roof panel is less than a distance of the guide limb from the underside of the at least one transparent roof panel.

5. The glass roof arrangement according to claim 1 , wherein each of the guide rails comprises plastic.

6. The glass roof arrangement according to claim 1 , wherein each of the edge limbs has an edge region facing the underside of the at least one transparent roof panel, the edge region including an elastically flexible damping material.

7. The glass roof arrangement according to claim 1 , wherein the edge limb of each guide rail includes an inner surface facing sidewardly and inwardly, the guide limb of each guide rail includes an upper surface facing towards the underside of the at least one transparent roof panel, the inner surface of the edge limb, the upper surface of the guide limb and the underside of the at least one transparent roof panel together forming and delimiting the respective lateral guide channel.

8. The glass roof arrangement according to claim 7 , wherein the lateral guide channels open inwardly towards one another and towards an interior of the motor vehicle.

9. The glass roof arrangement according to claim 1 , wherein each edge limb has an upper edge region disposed immediately adjacent the underside of the at least one transparent roof panel.

10. The glass roof arrangement according to claim 9 , wherein the upper edge region of each of the edge limbs includes a damping material disposed in direct contact with the undersigned of the at least one transparent roof panel.

11. A glass roof arrangement for a motor vehicle having a vehicle body with roof structure parts, said glass roof arrangement comprising:
a support frame, said support frame, in a use state on the motor vehicle, being fixed to the roof structure parts thereof;
a transparent roof panel fixed to said support frame and having an upper side and a lower side, said lower side facing opposite said upper side and towards an interior of the motor vehicle;
a pair of guide rails fixed to said lower side of said transparent roof panel in a spaced-apart manner from one another, each said guide rail being elongated and having a longitudinal dimension; and
a shading device disposed adjacent said lower side of said transparent roof panel and including a shading structure, said shading structure having a pair of edge portions disposed in spaced-apart relation with one another in a direction transverse to the longitudinal dimensions of said guide rails, each of said guide rails having a first limb oriented substantially orthogonally to said lower side of said at least one transparent roof panel, each said first limb having an upper edge portion disposed adjacent said lower side of said transparent roof panel and a lower edge portion spaced downwardly from said upper edge portion, each of said guide rails further including a second limb attached to said first limb adjacent said lower edge portion thereof and oriented substantially parallel to, and spaced downwardly from, part of said lower side of said transparent roof panel, said first limb, said second limb and said part of said lower side of said transparent roof panel together defining a guide channel, said guide channels of said guide rails opening towards one another, and said edge portions of said shading structure being slidingly engaged within the respective said guide channels such that said shading structure is displaceable along and relative to said guide rails.

12. The glass roof arrangement according to claim 11 , wherein said first limb of each of said guide rails has oppositely facing first and second sides, said second limb being disposed at said first side of said first limb, each said guide rail comprising a third limb disposed at said second side of said first limb, said third limb being attached to said first limb adjacent said lower edge portion thereof, said second and third limbs of each said guide rail projecting from said first limb in opposite directions from one another.

13. The glass roof arrangement according to claim 12 , wherein said third limb of each said guide rail is spaced downwardly from said lower side of said transparent roof portion such that a gap is formed between said lower side of said transparent roof portion and an upwardly facing surface of said third limb to accommodate a bead of adhesive.

14. The glass roof arrangement according to claim 13 , wherein a distance defined between said lower side of said transparent roof portion and said upwardly facing surface of said third limb is less than a distance defined between an upwardly facing surface of said second limb and said part of said transparent roof panel.

15. The glass roof arrangement according to claim 11 , wherein said upper edge portions of said first limbs are disposed in abutting relation with the respective said part of said lower side of said transparent roof panel, and each said upper edge portion includes a damping material.

16. A glass roof arrangement for a motor vehicle, said glass roof arrangement comprising:
a support frame;
a transparent roof panel having a peripheral edge portion fixed to said support frame, an upper side and a lower side, said lower side facing opposite
