a vehicle seat comprising a backrest, wherein the reflected light beams are directed toward an eye box that is located between the windshield and the vehicle seat;
wherein the head-up display unit is attached to the vehicle seat with a fastener where the vehicle seat is fixed with respect to inclination of the backrest of the vehicle seat; and
wherein a seat inclination compensator located in the fastener detects the inclination of the backrest.
2. The head-up display system as claimed in claim 1 , wherein the head-up display unit has an image distorter that pre-distorts dependent upon on the adjustment of the vehicle seat.
3. The head-up display system as claimed in claim 1 , wherein the system is configured for use in a vehicle, and the head-up display unit is arranged on the side of the vehicle seat that faces the outer side of the vehicle.

5. A head-up display system for a motor vehicle comprising:
a partially reflecting transparent pane with a region of nearly uniform curvature;
a head-up display unit comprising a plane mirror, and a moveable mirror, wherein the head-up display unit generates light beams which are reflected by the plane mirror and moveable mirror to the partially reflecting transparent pane and which are at least partially reflected by the partially reflecting transparent pane; and
a vehicle seat comprising a backrest,
wherein the head-up display unit is attached to the vehicle seat with a fastener where the vehicle seat is fixed with respect to inclination of the backrest, wherein a seat inclination compensator located in the fastener detects the inclination of the backrest, and wherein the vehicle seat is facing toward the partially reflecting transparent pane.
6. The head-up display system as claimed in claim 5 , wherein the head-up display unit has an image distorter that pre-distorts dependent upon the adjustment of the vehicle seat.
