Curtain airbag and curtain airbag device
First Claim
1. A curtain airbag configured to deploy downward along a side surface of a vehicle interior, comprising:
- a curtain airbag body configured to be inflated with gas from an inflator; and
a tie panel disposed on a side surface of an intermediate portion of the curtain airbag body in a front-rear direction of a vehicle (hereinafter, referred to as a tie panel installation portion) on a side opposite the vehicle interior, the tie panel being connected to an upper portion and a lower portion of the curtain airbag body with an upper connection means and a lower connection means,the curtain airbag body including;
a first panel on a vehicle interior side;
a second panel on a side opposite the vehicle interior side; and
a connected portion connecting the first panel and the second panel to each other,the connected portion including;
a peripheral connected portion extending along peripheral portions of the first panel and the second panel; and
an inner connected portion positioned inward from the peripheral connected portion,a length between the upper connection means and the lower connection means in the tie panel being shorter than a length between the upper connection means and the lower connection means in the curtain airbag body, whereinthe inner connected portion includes radial connected portions extending radially in three directions or in more than three directions from a middle or from a position near the middle of the tie panel installation portion, andthe radial connected portions extending in the three directions extend at least obliquely upward or obliquely downward from the middle or from the position near the middle of the tie panel installation portion, wherein the radial connected portions extending from the middle or from the position near the middle of the tie panel installation portion include a first radial connected portion extending forward and upward, a second radial connected portion extending forward and downward, a third radial connected portion extending rearward and downward, and a fourth radial connected portion extending rearward and upward.

Abstract
A curtain airbag and a curtain airbag device that reduce the energy transferred to an occupant even though an internal inflation pressure in a curtain airbag body is low are provided. A tie panel 3 is disposed on a curtain airbag body 2 on a side opposite a vehicle interior. An upper portion and a lower portion of the tie panel 3 are connected to the curtain airbag body 2 by sewing. In an area overlapped with the tie panel 3, the panels 5 and 6 of the curtain airbag body 2 are connected to each other by sewing with linearly connected portions 32 to 35, which extend radially in four directions, so as to form four inflation chambers 8 to 11. The curtain airbag body 2 and the tie panel 3 define a space S therebetween when the curtain airbag body 2 is inflated. The space S is in a pyramidal shape in which a portion around an intersection M of the connected portions 32 to 35 protrudes the most.
