Abstract

The invention relates to a vehicle seat (2) for reducing kinetosis-related disorders of an occupant (1) on the vehicle seat (2) during driving of a vehicle having an automatically moveable headrest (2.2) and a seat belt assigned to the vehicle seat (2). In accordance with the invention, the vehicle seat (2) and/or the headrest (2.2) move for acceleration compensation or for acceleration reduction, and/or a connection of the occupant (1) to the vehicle seat (2) is increased at least by means of the seat belt before the onset of acceleration.

First claim

1 . Device for reducing kinetosis-related disorders of an occupant ( 1 ) on the vehicle seat ( 2 ) during driving of a vehicle having a vehicle seat ( 2 ), an automatically moveable headrest ( 2 . 2 ), and a seat belt assigned to the vehicle seat ( 2 ),
characterised in that the vehicle seat ( 2 ) and/or the headrest ( 2 . 2 ) is actively moveable for acceleration compensation or acceleration reduction, and/or a connection of the occupant ( 1 ) to the vehicle seat ( 2 ) is increased at least by means of the seat belt before the onset of acceleration.

2 . Device according to claim 1 ,
characterised in that the headrest ( 2 . 2 ) is coupled to an actuator system which is designed to move the headrest ( 2 . 2 ) automatically, at least in sections, counter to an expected direction of acceleration of at least the head of the occupant ( 1 ) before the onset of the acceleration.

3 . Device according to claim 1 or 2 ,
characterised in that a seat frame of the vehicle seat ( 2 ) is rotatably mounted at least in sections around a vehicle transverse axis.

4 . Device according to claim 3 ,
characterised in that the vehicle seat ( 2 ) is coupled to a torque motor and/or a linear drive with transmission, wherein a torque motor and/or a linear drive with transmission is/are designed for an at least sectional rotation of the vehicle seat ( 2 ) around the vehicle transverse axis.

5 . Device according to one of the preceding claims,
characterised in that a seat frame of the vehicle seat ( 2 ) is rotatably mounted at least in sections about a vehicle vertical axis by means of a rotary plate.

6 . Device according to one of the preceding claims,
characterised in that a reversible belt tensioner is provided for tightening the worn seat belt before the onset of acceleration.

7 . Device according to one of the preceding claims,
characterised in that the vehicle seat ( 2 ) comprises a seat back ( 2 . 1 ) and a vertically displaceable shoulder clamp ( 3 ) which can be extended from the seat back ( 2 . 1 ) for connecting at least an upper body of the occupant ( 1 ) to the vehicle seat ( 2 ).

8 . Device according to claim 7 ,
characterised in that the shoulder clamp ( 3 ) comprises padding in which at least one vibration motor and/or air cushion is/are integrated.

9 . Device according to one of the preceding claims,
characterised in that the vehicle seat ( 2 ) comprises a seat back ( 2 . 1 ) and a flat fabric which can be pulled out of a side panel of the seat back ( 2 . 1 ) and one end of which is fastened inside the seat panel and the opposite end of which can be connected to an opposite side panel of the seat back ( 2 . 1 ) for the flat connection of the upper body of the occupant ( 1 ).

10 . Vehicle having a device according to one of the preceding claims.
