Patent attributes
The area of panels used in an airbag that inflates so that a recess extends in the vertical direction between a left chamber and a right chamber. The airbag 1 includes a front chamber 2 positioned in the forefront when viewed from the position of an occupant, the left chamber 3 communicating with the front chamber 2 to be inflated on the left side in front of the occupant, and the right chamber 4 communicating with the front chamber 2 to be inflated on the right side in front of the occupant. In a state in which the airbag 1 is inflated, there is no extending member such as a tie panel between the distal parts of the left chamber 3 and the right chamber 4, and a recess 6 formed between the distal parts of the left chamber 3 and the right chamber 4 opens toward the occupant, and continuously extends from the upper part of the airbag 1 to the lower part thereof. A tether belt 7 extends between the upper part of the deepest part of the recess 6, and the bottom part of the airbag 1 so that the upper part of the recess 6 is pulled to the inside of the airbag 1.
