Abstract

An airbag (11) by which, when a vehicle (20) including two seats arranged in a vehicle width direction is subjected to a side collision, an occupant (P10, P11) sitting in a seat (22L, 22R) at the opposite side of the collision is restricted from moving to the collision side. The airbag (11) has, in the maximally-expanded status, an outline shape seen from the front side of the vehicle. This outline shape has: an airbag upper part (11U) that forms a part equal to or higher than a position corresponding to a shoulder of a seat back (25L, 23R) and that protects the neck and head for example of the occupant (P10, P11); and an airbag lower part (11D) that forms a part equal to or lower than a position corresponding to a shoulder of the seat back (25L, 23R) and that protects the shoulder and arm for example of the occupant (P10, P11). The airbag (11) is configured to have an entire shape that has the inner outline of the occupant (P10, P11) in the vehicle width direction.

Description

technical field [0001] The present invention relates to an airbag for protecting occupants in a car, and more particularly to an airbag that suppresses the body of an occupant seated on a seat on the opposite side of the collision direction from moving toward the collision side under the action of the reaction force when the side of the vehicle is collided. Moving airbags. Background technique [0002] Airbag devices are widely used as protective devices for cushioning the impact on occupants in the event of a frontal collision of an automobile. The airbag device in the prior art is installed in the steering device or the instrument panel in front of the occupant. When the front of the car is collided, the airbag is inflated in front of the driver's seat and the passenger's seat. occupants move forward. As a result, when the front of the car is collided, the occupants in the driver's seat and the passenger's seat can be effectively protected. [0003] In recent years, att...
