In the case of a head-up display in which the light of an image-forming device (10) can be projected onto a projection surface (12) via at least one mirror (1), and the at least one mirror (1) can be rotated about a first axis of rotation (3) by means of an adjusting device (2, 4, 5, 6, 7, 8), and so the position of an image that can be projected onto the projection surface (12) can be varied, it is provided that the adjusting device has at least one sloping segment (5, 6) that is mounted in a fashion capable of rotation about a second axis of rotation (9), the second axis of rotation (9) not being perpendicular to the surface of the at least one sloping segment (5, 6), that the at least one mirror (1) is connected to a supporting unit (2, 2a, 2b) , that the supporting unit (2, 2a, 2b) is pressed against the sloping segment (5, 6) at a spacing from the second axis of rotation, and that, by rotating the at least one sloping segment (5, 6) , the supporting unit (2, 2a, 2b) slides over the sloping segment (5, 6), and the mirror (1) is thereby rotated about the first axis of rotation (3).
A head-up display in which the light of an imageforming device (10) can be projected onto a projection surface (12) via at least one mirror (1), and the at least one mirror (1) can be rotated about a first axis of rotation (3) by means of an adjusting device (2, 4, 5, 6, 7, 8), and so the position of an image that can be projected onto the projection surface (12) can be varied, characterized in that the adjusting device has at least one sloping segment (5, 6) that is mounted in a fashion capable of rotation about a second axis of rotation (9), the second axis of rotation (9) not being perpendicular to the surface of the at least one sloping segment (5, 6), in that the at least one mirror (1) is connected to a supporting unit (2, 2a, 2b), in that the supporting unit (2, 2a, 2b) is pressed against the sloping segment (5, 6) at a spacing from the second axis of rotation, and in that, by rotating the at least one sloping segment (5, 6), the supporting unit (2, 2a, 2b) slides over the sloping segment (5, 6), and the mirror (1) is thereby rotated about the first axis of rotation (3).
A head-up display in which the light of an image-forming device (10) can be projected via at least one mirror (1) onto a projection surface (12), and the at least one mirror (1) can be rotated by means of an adjusting device (2, 4, 5, 6, 7, 8) about a first axis of rotation (3), and so the position of an image that can be projected onto the projection surface (12) can be varied, characterized in that the at least one mirror (1) is connected to a sloping segment (5A, 6A) at a spacing from the first axis of rotation (3), in that a supporting surface is present that bears against the sloping segment (5A, 6A) at the spacing in a fashion capable of rotation about a second axis of rotation, the sloping segment (SA, 6A) not being arranged perpendicular to the second axis of rotation, such that owing to a rotation of the support surface about the second axis of rotation the supporting surface slides over the sloping segment (5A, 6A) and the mirror is thereby rotated about the first axis of rotation (3).
The head-up display as claimed in one of the preceding claims, characterized in that the drive for the rotation about the second axis of rotation comprises a stepping motor.
