  • Apparatus for actuating the safety devices for vehicle occupants
    Patent number: 5668528
    Abstract: An apparatus for actuating a plurality of safety devices equipped in a vehicle for protecting occupants from an impact of a collision has a plurality of squibs (4,5) connected in series with each other so as to form a series circuit (6) and ignited by a current flowing through and conformed to one and the same standard. A power source (3) supplies electrical energy to the series circuit (6), and a collision detector (7) allows a current to flow from the power source (3) to said series circuit (6) when detecting a collision. A required energy for igniting all of the squibs (4,5) is thus supplied before the series circuit (6) opens electrically at one squib.
