When the airbag inflates before the tether is fully extended and interferes with an interfering object such as an occupant, for example, when the interfering object is located near the center of the tether in the width direction, the inflating airbag is inflated. Gas flows from the upper part of the airbag body above the tether, through the gap between the left and right edges of the tether and the peripheral wall of the airbag body, to the part below the tether of the airbag body. Thus, the force protruding rearward of the airbag is weakened, and the impact on the interfering object can be reduced.

When the airbag inflates before the tether is fully extended and interferes with an obstacle located near one of the left and right edges from the center of the tether, the inflation gas is supplied to the tether of the airbag body. Air flows from the upper part to the lower part of the airbag body through the gap between the other left and right edges of the tether far from the interference and the peripheral wall of the airbag body. The force protruding rearward of the bag is reduced, and the impact on the interfering object can be reduced.

If the width of the tether on the ceiling wall side is set to 200 mm or more and 80% or less of the width of the airbag when inflated, the distance between the edge of the tether and the peripheral wall of the airbag body is reduced. Since the left and right gaps can each secure at least 10% of the width of the airbag at the time of inflation, for inflation from a portion above the tether of the airbag body to a portion below the tether of the airbag body. The gas flow is smooth, and the impact on the interfering object can be further reduced.In addition, since the tether width is secured to 200 mm or more, even if the interfering object at the time of inflation is the occupant's head, Exactly, the impact on the head can be reduced.

If the tether is configured so that the left and right edges of the portion projecting rearward from the instrument panel are parallel to each other and extend rearward, the width of the tether at the portion projecting rearward from the instrument panel can be obtained. The dimensions can be made as wide as possible. Therefore, when the tether is fully extended, the inflation gas flows from the gap between the left and right edges of the tether and the peripheral wall of the airbag body, and the lower portion of the airbag body below the tether is inflated. Even if the occupant's head is located on the side, the downwardly flowing inflation gas can be located on the peripheral wall as much as possible, and the pressing force of the inflation gas acting on the occupant's head should be minimized. Can be.

Further, the respective gaps between the left and right edges of the tether and the peripheral wall of the main body when the airbag is inflated,
If they are set to be equal to each other, when an interference object is located near the center in the width direction of the tether, the inflation gas flows from the upper part of the airbag body to the left and right edges of the tether and the peripheral wall of the airbag body. When flowing to the portion below the tether of the airbag body through the gap with the portion, the inflation gas flows evenly to the left and right, and the impact on the interfering object can be reduced in a well-balanced manner.
