Abstract
The present invention provides a side curtain air bag facilitating the control of tension with the airbag. The side curtain air bag includes chambers expanded by gas supplied from a gas generator, and expands and develops into a curtain shape along a side part of a vehicle so as to protect vehicle occupants. The side curtain air bag includes primary chambers which expand to form the side curtain air bag, and a secondary chamber which expands after the primary chambers to apply additional tension across the expanded side curtain air bag. The secondary chamber includes an opening communicating with the primary chamber.

3. A side curtain air bag, which includes chambers expanded by gas supplied from a gas generator, and expands and develops into a curtain shape along a side part of a vehicle so as to protect vehicle occupants, the side curtain air bag comprising:
-
at least one primary chamber which expands by gas supplied by the gas generator so as to protect an occupant;
at least one secondary chamber which expands by gas supplied by the gas generator, and wherein the secondary chamber is expanded and developed after the primary chamber is expanded and developed; and
at least two tethers, each tether having one end attached to the side curtain air bag at a joint end and the other end attached to a vehicle at a fixation end. wherein, when the side curtain air bag is expanded and developed, the primary chamber and the secondary chamber are arranged such that a portion or all of the primary chamber and a portion or all of the secondary chamber respectively overlap a virtual band, the virtual band being formed along a virtual line connecting the respective joint ends of the pair of tethers. - View Dependent Claims (5)
