Definitions
- the notification device may be provided in the occupant support device.
- the occupant can appropriately anticipate the change in the shape of the seat.
- the seat control device 76 controls the occupant support device 20 based on the inclination direction of the seat surface of the seat back 6 and the inclination amount of the seat surface of the seat back 6 (S4).
- the operation of the notification device 21 may be completed or may continue.
- the occupant support device 20 is the movable frame device 23 or the air cell device 41
- the movable frame device 23 and the air cell device 41 provided on the side opposite to the turning direction are operated, and the side of the seat 2 on the side opposite to the turning direction is operated. Protrude the part forward.
- the tilt plate device 61 the tilt plate device 61 is operated so that the front surface of the tilt plate 62 faces the turning direction.
- the seat control device 76 determines whether or not the occupant is gripping the steering wheel 71 based on the signal from the grip sensor 93, and when the steering wheel 71 is gripped by the occupant, the steering wheel 71 is gripped.
- the amount of operation of the occupant support device 20 may be smaller than that in the absence. According to this aspect, when the occupant is aware of the turning of the vehicle, unnecessary operation of the occupant support device 20 can be omitted.
