Front passenger’s SRS frontal airbag
The front passenger’s SRS frontal airbag uses a dual stage inflator. The inflator
operates in different ways depending on the severity of impact.
The total load on the seat is monitored by the passenger’s occupant detection
system weight sensor under the seat.
Using the total seat load and
