i-SRS Airbag System (Driver's and Front Passenger's Airbag): Notes
In case of a frontal collision, the i-SRS airbag system uses a seat belt tensioner and driver's seat belt outer lap tensioner as a body restraint device in addition to the impact-absorbing construction of the body shell as a function to mitigate the impact forces acting on the head and chest of the front seat occupant. The driver's airbag and the front passenger's airbag uses two inflators for a dual-stage output control system. In case of a collision at low or medium speed, the airbag is deployed while reducing the inflator output by means of a dual-stage ignition of each inflator, which helps to reduce the possibility of injury to the occupant. In case of a sudden collision at high speed, both inflators are ignited at the same time to restrain and protect the occupants. The system registers when a seated occupant is wearing the seat belt, and in some cases like a low-speed collision, the occupant may be restrained by the seat belt only.
