The side airbags are located in the front seat backs, and the side window airbags are located in the roof headlining on both sides of the car. In addition, pyrotechnic seat belt pretensioners are fitted to the inertia reels of the front seat belts.
The airbag of Fiat Punto and seat belt pyrotechnic safety systems are armed only when the ignition is switched on, however, a reserve power source maintains a power supply to the systems In the event of a break in the main electrical supply. The airbags are activated by a 'g' sensor (deceleration sensor), and controlled by an electronic control unit located under the centre of the facia. The side airbags and side window airbags are activated by severe side impact and operate in conjunction with the main system. The pyrotechnic seat belt pretensioners operate independently of the main system.
The airbags are inflated by a gas generator. which forces the bag out from its location in the steering wheel, facia, seat back frame or roof headlining.
