Claims

1. A mirror for a vehicle, in particular an aircraft, comprising:

at least one ultra-thin, hardened first glass sheet with a maximum thickness of 1.0 mm;

at least one fastening layer connected to a front side of the first glass sheet and comprising at least one polymer and at least one fire-retardant additive,

at least one hardened second glass sheet with a maximum thickness of 0.7 mm connected to the fastening layer, the second glass sheet positioned on a front side, remote from the first glass sheet, of the fastening layer connected to the first glass sheet, and

at least one mirror layer disposed between the first glass sheet and the second glass sheet.

2. The mirror as in claim 1, wherein the first glass sheet is chemically hardened.

3. The mirror as in claim 1, wherein the second glass sheet is chemically hardened.

4. The mirror as in claim 1, wherein at least one of the fire-retardant additives is formed by an organohalogen compound.

5. The mirror as in claim 1, wherein at least one of the fire-retardant additives is formed by an intumescent substance comprising melamine.

6. The mirror as in claim 1, wherein the fastening layer comprises at least one fibre-reinforced polymer.

7. The mirror as in claim 1, wherein the mirror layer is disposed between the first glass sheet and the fastening layer.

8. The mirror as in claim 1, wherein the mirror layer has a light transmission of between 10% and 80%.

9. The mirror as in claim 1, wherein a side of the mirror layer remote from the first glass sheet is at least partially provided with a coating which protects the mirror layer.

10. The mirror as in claim 1, wherein the fastening layer comprises a film.

11. The mirror as in claim 10, wherein the fastening layer further comprises an ionomer.

12. The mirror as in claim 1, wherein the fastening layer comprises at least one thermosetting polymer which is at least partially cured.

13. The mirror as in claim 12, wherein the thermosetting polymer is fibre-reinforced.

14. The mirror as in claim 1, wherein the fastening layer is substantially transparent.

15. The mirror as in claim 1, wherein the fastening layer has a maximum thickness of 2.5 mm.

16. The mirror as in claim 1, wherein the second glass sheet is directly connected to a front side, remote from the first glass sheet, of the fastening layer connected to the first glass sheet.

17. The mirror as in claim 1, wherein the second glass sheet is connected to the first glass sheet such that the fastening layer is enclosed by the second glass sheet and the first glass sheet.

18. The mirror as in claim 1, further comprising a laminate that comprises an adhesive layer for attaching the laminate to a bearing structure such as a wall.

19. The mirror as in claim 1, wherein the mirror comprises at least one additional material layer positioned on a front side of the fastening layer remote from the first glass sheet, wherein the at least one additional material layer is chosen from the group consisting of:

a decorative layer, a coloured layer, an additional fastening layer, an electronic layer, a reflective layer and an additional glass sheet.

20. The mirror as in claim 1, wherein at least a part of an end surface of at least one glass sheet is polished.

21. A method for manufacturing a mirror for a vehicle, comprising:

providing at least one ultra-thin hardened first glass sheet with a maximum thickness of 1.0 mm,

arranging a mirror layer on at least one front side of the first glass sheet, successively laying onto each other the first glass sheet provided with the mirror layer, a fastening layer comprising at least one polymer, wherein the fastening layer comprises at least one fire-retardant additive, and a hardened second glass sheet with a maximum thickness of 0.7 mm, and

laminating, using heat, the first glass sheet provided with the mirror layer and the fastening layer to form a mirror.

22. The method as claimed in claim 21, wherein the fastening layer arranged during step comprises at least one thermosetting polymer, and further comprising curing the thermosetting polymer being at least partially and preferably substantially wholly cured during the laminating.
