Device integrated into motor vehicle for combating motion sickness

The invention relates to an anti-motion-sickness device mounted to a motor vehicle (10), characterized in that the anti-motion-sickness device comprises:-a triaxial accelerometer configured to detect accelerations of the vehicle (10) along three axes and to emit corresponding acceleration signals; display means (12, 12 ', 12' ') of light markings adapted to form at least one first artificial horizontal line (14, 14') at a first inner surface (13) of the motor vehicle (10) and at least one second artificial horizontal line (16, 16 ') at a second inner surface (15, 15') of the motor vehicle (10), the first artificial horizon (14, 14 ') and the second artificial horizon (16, 16') are perpendicular or substantially perpendicular to each other; and a control unit, the control unit can receive the acceleration signal emitted by the accelerometer and can drive the display device (12, 12 ', 12' '), so that the first artificial horizontal line (14, 14') and the second artificial horizontal line (16, 16 ') are arranged
