Abstract
An airbag system and related method of inflating an airbag is disclosed. The airbag system has an airbag cushion having an interior cavity. At least one pyrotechnic gas generating compound is positioned within the interior cavity of the airbag cushion. At least one ignition source is in communication with the at least one pyrotechnic gas generating compound. A control unit is in communication with the at least one ignition source, wherein activation of the at least one ignition source by the control unit causes the at least one pyrotechnic gas generating compound to inflate the airbag cushion.
Claims17
An airbag system comprising:
- an airbag cushion having an interior cavity;
- at least one pyrotechnic gas generating compound positioned within the interior cavity of the airbag cushion;
- at least one electric ignition source in communication with the at least one pyrotechnic gas generating compound, the at least one electric ignition source comprising;
- an electric power source;
- one or more electric circuit boards located within the interior cavity of the airbag cushion and positioned on substantially opposing sides of the at least one pyrotechnic gas generating compound, wherein an electric arc is transmitted between the one or more electric circuit boards through the at least one pyrotechnic gas generating compound;
- and
- at least one wired connection between the electric power source and the one or more electric circuit boards;
- and
- a control unit in communication with the at least one electric ignition source, wherein activation of the at least one electric ignition source by the control unit causes the at least one pyrotechnic gas generating compound to inflate the airbag cushion.
An airbag system comprising:
- an airbag cushion having an interior cavity;
- at least one pyrotechnic gas generating compound positioned within the interior cavity of the airbag cushion;
- at least two electric circuit boards positioned within the interior cavity of the airbag cushion and positioned on substantially opposing sides of the at least one pyrotechnic gas generating compound, whereby the at least one pyrotechnic gas generating compound is positioned between the at least two electric circuit boards;
- at least one ignition source in communication with the at least two electric circuit boards;
- and
- a control unit in communication with the at least one ignition source, wherein activation of the at least one ignition source by the control unit causes an electric arc to be transmitted between the at least two electric circuit boards through the at least one pyrotechnic gas generating compound, thereby causing ignition of the at least one pyrotechnic gas generating compound, whereby the airbag cushion is inflated.
A method of inflating an airbag, the method comprising:
- providing an airbag cushion having an interior cavity and at least one pyrotechnic gas generating compound positioned within the interior cavity of the airbag cushion;
- positioning one or more electric circuit boards within the interior cavity of the airbag cushion and on substantially opposing sides of the at least one pyrotechnic gas generating compound;
- and
- activating at least one electric ignition source in communication with the one or more electric circuit boards with a control unit, thereby transmitting an electric arc between the one or more electric circuit boards through the at least one pyrotechnic gas generating compound, whereby the at least one pyrotechnic gas generating compound is ignited and the airbag cushion is inflated.
