Abstract: An airbag arrangement includes a middle side airbag confined between an arm-rest and a seat. The middle side airbag protects a driver of a vehicle and a passenger from the collision between the driver and the passenger upon vehicle collision. A cushion inflated from a back part of a driver seat is firmly fixed between the driver seat and an arm-rest to restrict the movement of occupants. The middle side airbag includes vertical sewed lines to vertically form a partition, or includes inclined sewed lines to inflate the middle side airbag toward at an expected collision position between the driver and the passenger. An inflator is provided on a lateral surface of a back part of the driver seat. As soon as air is injected into the middle side airbag, the middle side airbag is inflated while forming contact parts confined in the space between an arm-rest and a seat.
