Airbag - apparatus and device for the protection of the lower limbs of the vehicle occupant and device for the protection of the occupant at the time of a side collision of a vehicle with the use of the same

摘要

[Problem] it is an object, an airbag - a device for the improvement of the degree of freedom in the fixing of the reaction forces in accordance with the physical frame is capable of occupants, and a device for the protection of the lower limbs of an occupant in a vehicle and a device for the protection of an occupant at the time of a side collision of a vehicle with the use of the airbag - device. [Solution] the knees of an occupant of large form, the inertial force at the time of the collision is large, are formed by the collective energy absorption effect of the upper cylinder 121, 121 and the lower cylinder 122, 122 at the time of the collision reliably protected. In one case of an occupant of less than form, the inertial force at the time of the collision is low, loads of the upper cylinders 121, 121 and the lower cylinders 122, 122 in corresponding proportions according to the physical size of the occupant is exerted on the occupant, in order to the absorption of the impact to meet the moment of collision.
