Definitions

  • the present invention relates to a curtain airbag that inflates and deploys along a side surface in a vehicle compartment for the purpose of protecting an occupant during a vehicle side collision or rollover (rollover).
  • the curtain airbag is an airbag that is installed above the door and inflates and deploys along the side window of the vehicle when an impact occurs to protect the passenger.
  • a normal curtain airbag has a longer duration of pressure when inflated and deployed than a front airbag or the like. This is because when a rollover occurs following a side collision, the time during which an impact can occur is long. Thus, the curtain airbag maintains the inflated state until the rollover, thereby restraining the occupant and preventing release from the vehicle.
  • curtain airbag When an occupant collides with the inflated curtain airbag, the curtain airbag is deformed so as to bend outwardly. In connection with this, the load from a curtain airbag may act on a passenger

  • the deployment guide cloth is wrapped in a bag shape around the outer periphery of the cushion portion, and then folded upward from below, and is folded and sandwiched between the cushion portion and the rail inner panel.
  • the deployment guide cloth is deployed before the cushion portion due to the expansion force of the cushion portion, and is interposed between the cushion portion and the occupant head so that the protection performance of the occupant head by the cushion portion is improved. Trying to improve.
  • the deployment guide cloth of the curtain airbag described in Patent Document 1 is a cover that covers the periphery of the folded cushion portion in a bag shape.
  • the unfolding guide cloth is stored with its lower end folded in a roll shape between the cushion portion and the rail inner panel.
  • the deployment guide cloth stored in such a state does not unwind conveniently and may hinder the deployment behavior itself of the cushion portion, which may impair the protection performance of the occupant's head.
  • even if the deployment guide cloth is unwound as planned it is physically natural that the development of a part of the cloth opens relatively later than the other parts. Therefore, in the curtain airbag described in Patent Document 1, it is difficult to obtain one that sufficiently satisfies the passenger protection performance against the first impact.
