Airbag unit
First Claim
1. An airbag unit, comprising:
- at least one seat that is to be disposed in a vehicle, and capable of shifting between a first state being a state in which the seat is frontward-oriented in a front-rear direction of the vehicle and a second state being a state in which the seat is rearward-oriented in the front-rear direction of the vehicle;
a pair of side airbags that are expandable and deployable, and disposed in the seat on respective sides of the seat in a width direction of the vehicle;
a seat state detector that detects whether the seat is in the first state or the second state; and
an airbag deployment controller that performs a first deployment control to the pair of side airbags, on a condition that the seat state detector detects that the seat is in the first state, and performs a second deployment control to the pair of side airbags, on a condition that the seat state detector detects that the seat is in the second state, the second deployment control being in a reverse sequence from the first deployment control,wherein the vehicle comprises a vehicle side collision sensor, and the seat state detector detects whether the seat is in the first or second state after the vehicle side collision sensor detects a vehicle side collision.

Abstract
An airbag unit includes a seat, a pair of side airbags, a seat state detector, and an airbag deployment controller. The seat is reversely rotatable in a front-rear direction of a vehicle. The pair of side airbags are expansive and deployable, and incorporated in the seat on respective sides of the seat in a width direction of the vehicle. The seat state detector detects a rearward-oriented state of the seat, i.e., a state in which the seat is rearward-oriented in the front-rear direction. The airbag deployment controller performs a deployment control of the pair of side airbags, on a condition that the seat state detector detects the rearward-oriented state of the seat. The airbag deployment controller performs the deployment control in a reverse sequence from a deployment control in a frontward-oriented state of the seat, i.e., a state in which the seat is frontward-oriented in the front-rear direction.

14. An airbag system, comprising:
-
a seat that is rotatable to be in a first state in which the seat is oriented in a first direction, and a second state in which the seat is oriented in a second direction; a plurality of airbags that are disposed in the seat; a vehicle side collision sensor which detects a vehicle side collision; a seat state detector that, after the vehicle side collision sensor detects a vehicle side collision, detects whether the seat is in the first state or the second state; and a controller that deploys the plurality of airbags in a first sequence if the seat state detector detects that the seat is in the first state, and deploys the plurality of airbags in a second sequence different from the first sequence if the seat state detector detects that the seat is in the second state. - View Dependent Claims (15, 16, 17)

18. An airbag system, comprising:
-
a first plurality of airbags that are disposed in a first seat, the first seat being rotatable to be in a first state in which the first seat is oriented in a first direction, and a second state in which the first seat is oriented in a second direction; a second plurality of airbags that are disposed in a second seat, the second seat being rotatable to be in a first state in which the second seat is oriented in the first direction, and a second state in which the second seat is oriented in the second direction; a vehicle side collision sensor that detects a vehicle side collision; a seat state detector that, after the vehicle side collision sensor detects a vehicle side collision; detects whether the first seat is in the first state or the second state; and detects whether the second seat is in the first state or the second state; and a controller that; deploys the first plurality of airbags in a first sequence if the seat state detector detects that the first seat is in the first state, and deploys the first plurality of airbags in a second sequence different from the first sequence if the seat state detector detects that the first seat is in the second state; and deploys the second plurality of airbags in the first sequence if the seat state detector detects that the second seat is in the first state, and deploys the second plurality of airbags in the second sequence if the seat state detector detects that the second seat is in the second state.
