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.
1. A device for reducing a kinetosis-related disorder in an autonomous driving mode of a vehicle, comprising:
a vehicle seat with a headrest; and
an actuator system, wherein 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;
wherein a support region of the headrest comprises a material which is elastically switchable;
wherein 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 and such that the stiffened material stabilizes a position of the head of the occupant, when sunk into the support region, relative to the headrest which reduces an acceleration of the head of the occupant and which reduces a risk of kinetosis occurring to the occupant.
2. The device according to claim 1 , wherein metal threads are integrated into the material, wherein a magnetic field is generatable by the metal threads, and wherein the material is solidifiable by the magnetic field.
3. The device according to claim 1 , wherein the material is solidifiable when an electrical voltage is applied to the material.
4. The device according to claim 1 , wherein the material is solidifiable chemically and reversibly.
5. The device according to claim 1 , wherein the support region is surrounded, at least in sections, by a rigid structure.
6. The device according to claim 5 further comprising an actuator configured as a pincer element, wherein the actuator is disposed in a region of the rigid structure, and wherein a free end of the actuator projects into the support region in an activated state of the actuator.
7. The device according to claim 1 further comprising a support element which is movable in a direction of the occupant, wherein the support element is integrated into a seat back of the vehicle seat.
8. A vehicle, comprising:
the device according to claim 1 .
