Abstract

A vehicle seat includes a driving portion capable of changing a position of a seat (, a rear-seat airbag that is fixed to the seat and deploys between a seatback portion of the seat and an occupant seating space of a rear seat behind the seat, and a control portion configured to change the position of the seat with the driving portion, and adjust a deployment region of the rear-seat airbag, when a collision of a vehicle is predicted.

Claims

1. A vehicle seat comprising:

a driving portion that changes a position of a seat;

a rear-seat airbag that is fixed to the seat and deploys between a seatback portion of the seat and an occupant seating space of a rear seat behind the seat; and

a control portion configured to change a position of the seat with the driving portion and adjust a deployment region of the rear-seat airbag, when a collision of a vehicle is predicted.

2. The vehicle seat according to claim 1, wherein

the driving portion is configured to change an inclination angle of the seatback portion;

the rear-seat airbag is fixed to the seatback portion; and

the control portion is configured to change the inclination angle of the seatback portion to a predetermined angle with the driving portion when the collision of the vehicle is predicted.

3. The vehicle seat according to claim 1, wherein

the driving portion is configured to change a vehicle forward-rearward position of the seat;

and

the control portion is configured to change the vehicle forward-rearward position of the seat to a predetermined position with the driving portion when the collision of the vehicle is predicted.

4. The vehicle seat according to claim 1, wherein

the driving portion is configured to rotate the seat around an axis that extends in a vehicle up and down direction;

and

the control portion is configured to rotate the seat with the driving portion to a predetermined position around the axis that extends in the vehicle up and down direction.

5. The vehicle seat according to claim 1, further comprising:

a first detecting portion that detects an occupant seated in the seat,

wherein the control portion is configured to start changing the position of the seat with the driving portion earlier when an occupant is not detected by the first detecting portion than when an occupant is detected by the first detecting portion.

6. The vehicle seat according to claim 1, further comprising:

a second detecting portion that detects an occupant seated in the rear seat behind the seat,

wherein the control portion is configured to stop control that changes the position of the seat with the driving portion, when an occupant is not detected by the second detecting portion.

7. The vehicle seat according to claim 1, wherein the driving portion is at least one of a reclining motor that changes an inclination angle of the seatback portion and a forward-rearward sliding motor that changes a vehicle forward-rearward position of the seat.

8. The vehicle seat according to claim 1, further comprising a collision predicting apparatus that predicts the collision of a vehicle, the collision predicting apparatus including at least one of a camera and a radar device.
