Claims

1-43. -43. (canceled)

44. 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, which second glass sheet is 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 arranged between the first glass sheet and the second glass sheet.

45. Mirror as claimed in claim 44, wherein the first glass sheet is chemically hardened.

46. Mirror as claimed in claim 44, wherein the second glass sheet is chemically hardened.

47. Mirror as claimed in claim 44, wherein at least one fire-retardant additive is formed by an organohalogen compound.

48. Mirror as claimed in claim 44, wherein at least one fire-retardant additive is formed by an intumescent substance, in particular a substance comprising melamine.

49. Mirror as claimed in claim 44, wherein the fastening layer comprises at least one reinforced polymer, in particular a fibre-reinforced polymer.

50. Mirror as claimed in claim 44, wherein the mirror layer is arranged between the first glass sheet and the fastening layer.

51. Mirror as claimed in claim 44, wherein the mirror layer has a light transmission of between 10% and 80%.

52. Mirror as claimed in claim 44, 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.

53. Mirror as claimed in claim 44, wherein the fastening layer is formed at least partially by a film.

54. Mirror as claimed in claim 53, wherein the fastening layer is manufactured at least partially from an ionomer.

55. Mirror as claimed in claim 44, wherein the fastening layer comprises at least one thermosetting polymer which is at least partially cured.

56. Mirror as claimed in claim 55, wherein the thermosetting polymer is fibre-reinforced.

57. Mirror as claimed in claim 44, wherein the fastening layer is substantially transparent.

58. Mirror as claimed in claim 44, wherein the fastening layer has a thickness of a maximum of 2.5 mm.

59. Mirror as claimed in claim 44, 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.

60. Mirror as claimed in claim 44, wherein the second glass sheet is connected to the first glass sheet such that the fastening layer is substantially wholly enclosed by the second glass sheet and the first glass sheet.

61. Mirror as claimed in claim 44, wherein the laminate comprises an adhesive layer for attaching the laminate to a bearing structure such as a wall.

62. Mirror as claimed in claim 44, 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.

63. Mirror as claimed in claim 44, wherein at least a part of an end surface of at least one glass sheet is polished.

64. Aircraft comprising a mirror as claimed in claim 44.

65. Method for manufacturing a mirror for a vehicle, comprising the steps of:

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

B) arranging a mirror layer on at least one front side of the first glass sheet,

C) 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

D) laminating by means of heating the assembly formed during step C), thus forming the mirror.
