DEVICE FOR REDUCING KINETOSIS-RELATED DISORDERS OF AN OCCUPANT WHILE IN DRIVING MODE OF A VEHICLE, AND A VEHICLE

A device for reducing a kinetosis-related disorder in a driving mode of a vehicle includes a vehicle seat with a headrest and an actuator system. The vehicle seat and/or the headrest is adjustable by the actuator system to position the headrest relative to a head of an occupant on the vehicle seat. A support region of the headrest includes a material which is elastically switchable and the material is solidifiable when a pressure is exerted on the material such that the material stiffens when the head of the occupant sinks into the support region.
