Abstract
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 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. 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), the at least one mirror (1) is connected to a supporting unit (2, 2a, 2b), the supporting unit (2, 2a, 2b) is pressed against the sloping segment (5, 6) at a spacing from the second axis of rotation, and 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).
