Abstract
An air-bag device capable of improving degree of freedom in setting of reaction forces according to physical frames of occupants, a vehicle occupant's lower limb protecting device and a device for protecting an occupant at the time of vehicle side collision using the air-bag device. Knees of an occupant of large build whose inertia load at the time of collision is great are assuredly protected by collective energy absorbing action of the upper cylinders (121, 121) and the lower cylinders (122, 122) at the time of collision. In a case of an occupant of small build whose inertia load at the time of collision is small, loads from the upper cylinders (121, 121) and the lower cylinders (122, 122) are exerted on the occupant in appropriate proportions according to physical size of the occupant to fulfill impact absorption at the time of collision.
