the outer surface of the first attachment piece is flush with the outer major surfaces of the first glass piece and the second glass piece.
2. The multi-part glazing according to claim 1 , wherein the first glass piece is the same size as or larger than the second glass piece.
3. The multi-part glazing according to claim 1 , wherein the first glass piece has a thickness greater than or equal to a thickness of the second glass piece.
4. The multi-part glazing according to claim 1 , further comprising a third glass piece, wherein the second glass piece is on one side of the first glass piece and the third glass piece is on an opposite side of the first glass piece, and
a second attachment piece provided between the first glass piece and the third glass piece to connect the first glass piece and the third glass piece,
wherein the outer major surface of the first glass piece is arranged in a continuous surface with the outer major surface of the third glass piece via an outer surface of the second attachment piece, and
the outer surface of the second attachment piece is flush with the outer major surfaces of the first glass piece and the third glass piece.
5. The multi-part glazing according to claim 1 wherein the first glass piece comprises a laminated glass piece, and wherein the laminated glass piece comprises a first glass sheet, a second glass sheet, and a polymer interlayer arranged between the first and second glass sheets.
6. The multi-part glazing according to claim 1 , wherein the outer surface of the first attachment piece, the outer major surface of the first glass piece, and the outer major surface of the second glass piece form an outer surface of the multi-part glazing, and wherein the outer surface of the first attachment piece is at the smallest radius of curvature in the outer surface of the multi-part glazing.
7. The multi-part glazing according to claim 6 , wherein the smallest radius of curvature in the outer surface of the multi-part glazing is smaller than the allowable curvature of the first glass piece and the second glass sheet.
8. The multi-part glazing according to claim 6 , wherein the smallest radius of curvature among the surfaces in the surface continuation is not more than 1000 mm.
9. The multi-part glazing according to claim 1 , wherein at least one of the first glass piece and the second glass piece has an inner surface printed with a black ceramic layer.
10. The multi-part glazing according to claim 1 , wherein the multi-part glazing is assembled as a part of a vehicle, and wherein the multi-part glazing wraps front pillars or rear pillars of the vehicle when assembled.
11. The multi-part glazing according to claim 1 , wherein the first glass piece is a vehicle windshield, a vehicle rear window or a vehicle sunroof.
12. The multi-part glazing according to claim 1 , wherein the first attachment piece includes a structural member used for assembling.
13. The multi-part glazing according to claim 1 , wherein the first attachment piece includes a structural member providing a function for a vehicle.
14. The multi-part glazing according to claim 1 , wherein the first attachment piece includes a structural member configured to interact with an accessory in the vehicle.
15. A method for producing a multi-part glazing, the method comprising:
preparing a first mold half and placing first and second glass pieces on prescribed positions on the first mold half;
setting a second mold half over the first mold half and the first and second glass pieces such that there is a cavity between the first and second glass pieces;
introducing a resin material into the cavity between the first and second mold halves to form an attachment piece; and
releasing the first and second mold halves from the first and second glass pieces and the resin material to obtain the multi-part glazing.
16. The method for producing a multi-part glazing according to claim 15 , wherein introduction of the resin material is done by a bicolor molding.
17. The method of claim 15 producing a multi-part glazing as defined in claim 1 .
18. The multi-part glazing according to claim 13 , wherein the structural member operates as or is equipped with an electronics device for providing light signals or picking up electromagnetic waves, or with electrical wiring for connecting a roof side with an engine room side.
19. The multi-part glazing according to claim 9 , wherein adhesive is applied to at least one of the black ceramic layers on the first glass piece or the second glass piece.
20. The multi-part glazing according to claim 1 , wherein the first attachment piece is formed with an outer resin material and an inner resin material.
