Airbag control arrangement for a vehicle including an airbag system having at least one airbag, a seat for occupancy by an occupant to be protected by the airbag(s), a seat position sensor system for determining the seat's position, and a control system for controlling deployment of the airbag(s). The control system is coupled to the seat position sensor system and determines deployment for the airbag(s) based on the determined position of the seat. Deployment of each airbag may be based only on the determined position of the seat, i.e., not based on information about the occupant or occupying item of the seat. The control system can suppress deployment of the airbag(s) or provide for a depowered deployment when the seat position sensor system indicates that the seat is in a forwardmost position.
