Modular vehicle roof
View Patent ↗A modular vehicle roof, in particular motor vehicle roof, is proposed which has a strong outer roof skin as its outer shell and an inner shell of foamed plastics connected firmly thereto, preferably foamed thereon, in the manner of the sandwich. A preferably transparent panel of glass or plastics, which allows light to reach the vehicle interior, is inserted into the vehicle roof and attached and sealed thereto in a particular way, approximately flush with the outer surface. The modular vehicle roof is simple and economic to produce, is light and has only a small structural height.
1. A vehicle roof assembly, comprising:
an outer skin having an opening through the outer skin;
a transparent panel aligned with the opening in the outer skin; and
a plastic layer bonded to at least one side of the outer skin and having a flange portion sealingly connected with an outer edge of the transparent panel.
2. The roof assembly of claim 1 , wherein the plastic layer comprises a foamed plastic secured to the outer skin.
3. The roof assembly of claim 2 , wherein the flange portion of the foam plastic is foamed onto the edge of the transparent panel.
4. The roof assembly of claim 1 , wherein the outer periphery of the transparent panel has a smaller dimension than an inner periphery of the outer skin opening and including a seal member extending between the outer periphery of the transparent panel and the inner periphery of the outer skin opening.
5. The roof assembly of claim 4 , wherein the seal member comprises some of the plastic of the plastic layer.
6. The roof assembly of claim 4 , wherein the seal member comprises a generally T-shaped rubber member having flange strips engaging corresponding portions of the outer skin and the transparent panel.
7. The roof assembly of claim 6 , wherein the outer skin includes a depression near the edge of the opening and wherein the flange of the seal member is at least partially received onto the depression.
8. The roof assembly of claim 4 , wherein the seal member comprises a first portion attached to the outer skin near the edge of the opening, a second portion extending between the inner periphery of the opening and the outer periphery of the transparent panel and a third portion engaging one side of the transparent panel near the peripheral edge of the panel.
9. The roof assembly of claim 8 , wherein the flange portion of the plastic layer extends further toward a center of the transparent panel then the third portion of the seal member.
10. The roof assembly of claim 1 , wherein the plastic layer has a first thickness across a portion of the plastic layer and a second, greater thickness at the flange portion.
11. The roof assembly of claim 1 , including an adhesion promoter secured to at least a portion of the transparent panel that is secured to the plastic layer flange.
12. The roof assembly of claim 1 , including a reinforcing profile supported by the plastic layer near an edge of the plastic layer flange, the reinforcing profile being adapted to support another member selectively connected to the reinforcing profile.
13. The roof assembly of claim 1 , wherein the transparent panel is supported within the opening exclusively by the plastic layer.
14. The roof assembly of claim 1 , wherein a portion of the plastic layer is coextensive with the side of the outer skin.
15. The roof assembly of claim 1 , wherein the outer skin has a folded edge at the opening and wherein the edge is surrounded by the plastic layer.
16. The roof assembly of claim 1 , wherein there is no overlap between the outer skin and the transparent panel.
17. A vehicle roof assembly, comprising:
an outer skin having an opening through the outer skin;
a transparent panel aligned with the opening in the outer skin; and
a plastic layer secured to at least one side of the outer skin and having a flange portion sealingly connected with an outer edge of the transparent panel, the plastic layer securing the outer skin and the transparent panel together such that the transparent panel is maintained within the opening.
18. The roof assembly of claim 17 , wherein the plastic layer is foamed onto the side of the outer skin and the outer edge of the transparent panel.
19. The roof assembly of claim 17 , wherein at least a portion of the plastic layer is bonded to and coextensive with the side of the outer skin.
