Vehicle curtain airbag apparatus
A vehicle curtain airbag apparatus includes an airbag cushion disposed on a side portion of a vehicle and including an active area inflated by gas and a plurality of inactive areas into which the gas is not introduced and a control tether to assist deployment of the airbag cushion. The control tether connects the plurality of inactive areas of the airbag cushion in a state in which a portion of the airbag cushion is folded.
1 . A vehicle curtain airbag apparatus comprising:
an airbag cushion disposed on a side portion of a vehicle and including an active area configured to be inflated by gas and a plurality of inactive areas into which the gas is not introduced; and
a control tether comprising a main body forming an exterior thereof and configured to assist deployment of the airbag cushion,
wherein the control tether connects the plurality of inactive areas of the airbag cushion in a state in which a portion of the airbag cushion is folded to form a folded portion, and
wherein the control tether includes a slit formed therein and configured to assist rupture of the main body of the control tether while the airbag cushion deploys to unfold the folded portion of the airbag cushion.
2 . The vehicle curtain airbag apparatus of claim 1 , wherein the airbag cushion includes a main body forming an exterior thereof,
wherein the main body of the airbag cushion includes a first panel configured to come into contact with a passenger and a second panel coupled to the first panel and configured not to contact the passenger, and
wherein the control tether is disposed on the second panel.
3 . The vehicle curtain airbag apparatus of claim 2 , wherein
the airbag cushion includes a first bonding portion disposed along an edge of the main body of the airbag cushion and forming the active area in the main body of the airbag cushion, and
the control tether is disposed outside the first bonding portion before the airbag cushion is folded.
4 . The vehicle curtain airbag apparatus of claim 3 , wherein
the airbag cushion includes a plurality of second bonding portions disposed inside the first bonding portion and forming the plurality of inactive areas inside the first bonding portion, and
the main body of the control tether is fixed to one of the plurality of second bonding portions of the airbag cushion in a state in which the portion of the airbag cushion is folded.
5 . The vehicle curtain airbag apparatus of claim 3 , wherein
a first end portion of the main body of the control tether is fixed to an outer side of the first bonding portion of the airbag cushion, and
the slit of the control tether is disposed proximate to the first end portion of the main body.
6 . The vehicle curtain airbag apparatus of claim 4 , wherein a second end portion of the main body of the control tether is coupled to one of the plurality of second bonding portions of the airbag cushion in the state in which the portion of the airbag cushion is folded.
7 . A vehicle curtain airbag apparatus comprising:
an airbag cushion disposed on a side portion of a vehicle and folded through a first folding process of folding a portion of the airbag cushion with respect to a first direction as a center and a second folding process of rolling the airbag cushion with respect to a second direction as an axis direction after the first folding process; and
a control tether coupled to the airbag cushion,
wherein the airbag cushion includes an active area configured to be inflated by gas and a plurality of inactive areas into which the gas is not introduced,
wherein the control tether is fixed to one of the plurality of inactive areas of the airbag cushion after the first folding process of the airbag cushion is completed,
the airbag cushion is configured to deploy through a first unfolding process of releasing a rolled state through the second folding process and a second unfolding process of releasing a folded state through the first folding process after the first unfolding process is completed, and
the control tether is configured to be ruptured while the second unfolding process of the airbag cushion is performed.
8 . The vehicle curtain airbag apparatus of claim 7 , wherein
the airbag cushion includes a first main body forming an exterior thereof,
the first main body includes a first panel configured to come into contact with a passenger and a second panel coupled to the first panel and configured not to contact the passenger, and
the control tether is disposed on the second panel.
