Problems solved by technology

[0004] However, in the existing airbag device for knee protection, when the passenger is located in front of the normal position, the airbag protrudes to the passenger's side, that is, to the vehicle rear side, during the initial stage of inflation, and it may collide with the passenger's shins. Interference, therefore, there is still room for improvement in terms of limiting the protruding amount of the airbag to the rear side of the vehicle
