Device for reducing kinetosis-related disorders of an occupant during driving mode of a vehicle

A device that reduces kinetosis-related disorders of an occupant of a vehicle in an autonomous driving mode of the vehicle, comprising:

• a vehicle seat with a headrest;
• a seat belt assigned to the vehicle seat which is configured to increase a connection of the occupant to the vehicle seat before an onset of an acceleration;
• an actuator system coupled to the headrest which is configured to move the headrest automatically, at least in sections, counter to an expected direction of an acceleration that will act on a head of the occupant before the onset of the acceleration which reduces the kinetosis-related disorders of the occupant of the vehicle, wherein the acceleration that will act on the head of the occupant and will cause the kinetosis-related disorders of the occupant of the vehicle is determined on a basis of a future trajectory of the vehicle;
• and
• a reversible belt tensioner, wherein the seat belt is tightenable by the reversible belt tensioner before the onset of the acceleration;
• wherein the actuator system is configured to move the headrest automatically counter to the expected direction of the acceleration in a lateral direction and in a longitudinal direction.
