摘要： A knee airbag device includes a column cover that covers a rear end portion of a steering column from below; and an airbag module. The airbag module is disposed in a column lower cover and includes a gas generation portion that generates gas and a knee airbag that is housed in the airbag module in a folded state, and is inflated and deployed by the gas supplied by the gas generation portion. The airbag module is connected to the steering column by a snap-fit action.

摘要： In a steering column provided with a knee airbag device to a vehicle, an airbag module, which is integrally provided on an airbag door formed separately from a column lower cover, is fitted to a column tube after a steering column body is assembled, and before a steering lock is fitted to the column tube. Then, after the airbag module is fitted to the column tube, a steering column sub-assembly, which is formed by fitting at least the steering lock to the column tube, is fitted to an instrument panel provided in a vehicle at a predetermined position. After the steering column sub-assembly is fitted to the instrument panel, the column lower cover and a column upper cover, which cover a rear end portion of the steering column, are fitted to the steering column.

摘要： A knee airbag device mounted on a steering column has an inner case in which a folded knee airbag is housed, and an outer case that is placed over the inner case. The outer case is fixed to a lower side of a vehicle-rear-side portion of a steering column that moves relative to a vehicle-front-side portion when a load equal to or greater than a threshold load is applied to the steering column in a direction of the axis of the steering column, and has a rigidity with which the shape of the folded knee airbag is maintained under normal conditions. The outer case has an opening formed in a region where the outer case would interfere with the vehicle-front-side portion when the vehicle-rear-side portion moves relative to the vehicle-front-side portion.
