Method and seat adjustment system for supporting relaxation of an occupant sitting on a vehicle seat of a motor vehicle

1. A method for supporting relaxation of an occupant sitting on a vehicle seat of a motor vehicle, the method comprising:

receiving a request for relaxation from the occupant by a seat controller of the motor vehicle;

moving at least a sitting portion of the vehicle seat back and forth according to a movement sequence specified by the seat controller defining a rocking motion for the occupant sitting on the vehicle seat, wherein the movement sequence is actuated by the seat controller via at least one of: at least one seat motion actuator integrated in or attached to the vehicle seat; or an active suspension system of the motor vehicle; and

assessing, by an interior sensor system of the motor vehicle, physical dimensions of the occupant and corresponding available clearances within a passenger cabin of the motor vehicle for performing the movement sequence, wherein the seat controller adapts the movement sequence depending on the available clearances.

2. The method according to claim 1 , further comprising:

assessing, by an autonomous driving unit of the motor vehicle, whether the motor vehicle operates in an autonomous driving mode, wherein the movement sequence is only actuated in case the autonomous driving mode fulfills predefined criteria.

3. The method according to claim 1 , wherein a seat frame and/or a seat base of the vehicle seat is moved according to the movement sequence.

4. The method according to claim 1 , wherein the vehicle seat is mounted to an interior structure of the motor vehicle via at least one fixation element, wherein the movement sequence is actuated by moving the vehicle seat at the at least one fixation element.

5. The method according to claim 1 , wherein the movement sequence is actuated by at least one of eccentric motors, linear motors, pneumatic systems or hydraulic systems.

6. The method according to claim 1 , wherein the movement sequence comprises at least one of linear movements along a horizontal axis (X, Y) and/or a vertical axis (Z), arcuate movements or circular movements.

7. The method according to claim 1 , further comprising:

assessing, by the interior sensor system of the motor vehicle, whether obstacles are located within the passenger cabin of the motor vehicle limiting and/or prohibiting movement of the vehicle seat according to the movement sequence, wherein the seat controller adapts the movement sequence depending on detected obstacles.

8. A seat adjustment system for supporting relaxation of an occupant sitting on a vehicle seat of a motor vehicle, comprising:

a seat controller configured to receive a request for relaxation from the occupant, to specify a movement sequence defining a rocking motion for the occupant sitting on the vehicle seat by moving at least a sitting portion of the vehicle seat back and forth and to actuate the movement sequence via at least one of:

at least one seat motion actuator integrated in or attached to the vehicle seat; or

an active suspension system of the motor vehicle; and

an interior sensor system configured to assess physical dimensions of the occupant and corresponding available clearances within a passenger cabin of the motor vehicle for performing the movement sequence, wherein the seat controller is configured to adapt the movement sequence depending on the available clearances.

9. The seat adjustment system according to claim 8 , further comprising:

an autonomous driving unit configured to assess whether the motor vehicle operates in an autonomous driving mode, wherein the seat controller is configured to only actuate the movement sequence in case the autonomous driving mode fulfills predefined criteria.

10. The seat adjustment system according to claim 8 , wherein the seat controller is configured to move a seat frame and/or a seat base of the vehicle seat according to the movement sequence.

11. The seat adjustment system according to claim 8 , wherein the vehicle seat is mounted to an interior structure of the motor vehicle via at least one fixation element, wherein the seat controller is configured to actuate the movement sequence by moving the vehicle seat at the at least one fixation element.

12. The seat adjustment system according to claim 8 , wherein the seat adjustment system comprises at least one of eccentric motors, linear motors, pneumatic systems or hydraulic systems to actuate the movement sequence.

13. The seat adjustment system according to claim 8 , wherein the movement sequence comprises at least one of linear movements along a horizontal axis (X, Y) and/or a vertical axis (Z), arcuate movements or circular movements.

14. A motor vehicle including the seat adjustment system according to claim 8 .

15. The seat adjustment system according to claim 8 , wherein the interior sensor system of the motor vehicle is further configured to assess whether obstacles are located within the passenger cabin of the motor vehicle limiting and/or prohibiting movement of the vehicle seat according to the movement sequence, wherein the seat controller is configured to adapt the movement sequence depending on detected obstacles.
