Abstract

An occupant protecting device including: a seat provided in a vehicle, the seat including a seat cushion, a seat back, and a headrest, and the seat being provided with an air bag that inflates and deploys at least to a front and both of left and right sides of a head of a seated occupant; and a control device that in the case of having detected or predicted a collision of the vehicle, causes the air bag to inflate and deploy, and in the case that the seat is facing an opposite side to a collision side when the collision has been detected or predicted, delays a timing of causing the air bag to inflate and deploy more compared to in the case that the seat is facing the collision side.

First claim

What is claimed is:

1. An occupant protecting device comprising:
a seat provided in a vehicle, the seat including a seat cushion, a seat back, and a headrest, and the seat being provided with an air bag that inflates and deploys at least to a front and both of left and right sides of a head of a seated occupant; and
a control device that in the case of having detected or predicted a collision of the vehicle, causes the air bag to inflate and deploy, and in the case that the seat is facing an opposite side to a collision side when the collision has been detected or predicted, delays a timing of causing the air bag to inflate and deploy more compared to in the case that the seat is facing the collision side, wherein
the device comprises a plurality of the seats, at least one of the plurality of seats is configured such that at least its front-rear orientation can be changed with respect to the vehicle, and
the control device includes a seat direction detecting sensor that detects the orientation of the at least one seat with respect to the vehicle.

2. The occupant protecting device according to claim 1 , further comprising a collision sensor electrically connected to the control device, wherein
the control device detects or predicts the collision of the vehicle based on a signal from the collision sensor.

3. The occupant protecting device according to claim 1 , wherein
the timing is a timing that internal pressure of the air bag becomes maximum.

4. An occupant protecting device comprising:
a seat provided in a vehicle, the seat including a seat cushion, a seat back, and a headrest, and the seat being provided with an air bag that inflates and deploys at least to a front and both of left and right sides of a head of a seated occupant; and
a control device that in the case of having detected or predicted a collision of the vehicle, causes the air bag to inflate and deploy, and in the case that the seat is facing an opposite side to a collision side when the collision has been detected or predicted, delays a timing of causing the air bag to inflate and deploy more compared to in the case that the seat is facing the collision side, wherein
the control device delays the timing of causing the air bag to inflate and deploy by delaying an actuation timing of an inflator supplying a gas for inflation to the air bag.

5. The occupant protecting device according to claim 4 , wherein
the seat is configured such that at least its front-rear orientation can be changed with respect to the vehicle, and
the control device includes a seat direction detecting sensor that detects the orientation of the seat with respect to the vehicle.

6. The occupant protecting device according to claim 4 , further comprising a collision sensor electrically connected to the control device, wherein
the control device detects or predicts the collision of the vehicle based on a signal from the collision sensor.

7. The occupant protecting device according to claim 4 , wherein
the timing is a timing that internal pressure of the air bag becomes maximum.

8. An occupant protecting device comprising:
a seat provided in a vehicle, the seat being provided with an air bag that inflates and deploys at least to a front and both of left and right sides of a head of a seated occupant; and
a control device that in the case of having detected or predicted a collision of the vehicle, causes the air bag to inflate and deploy, and changes a timing of causing the air bag to inflate and deploy depending on an orientation of the seat with respect to a direction of the detected or predicted collision.

9. The occupant protecting device according to claim 8 , further comprising a collision sensor electrically connected to the control device, wherein
the control device detects or predicts the collision of the vehicle based on a signal from the collision sensor.

10. The occupant protecting device according to claim 8 , wherein
the timing is a timing that internal pressure of the air bag becomes maximum.
