Abstract
An apparatus includes an airbag having first and second portions formed by seaming silicon coated cloths where the second portion has a vent. The airbag is folded in a seatback, deploys to a side of an occupant by a gas supply, and receives an occupant lumbar at the first portion and a chest at the second portion. An inflator extends across the first and second portions towards a rear of the vehicle and includes a gas injector in the first portion. A gas distributing member has a discharge port opening into the first portion and a passage opening into the second portion between the distributing member and a surface of the inflator. The distributing member is fitted to the surface and distributes gas from the inflator to the airbag so the flow rate is higher in the first portion. A communicating portion transfers gas between the first and second portions.
