Abstract
A steering column device with a knee airbag device includes a steering column provided with a telescopic mechanism; a column cover that covers the rear end portion of the steering column; an airbag module, provided inside the column cover, which includes a gas generation device that generates gas, and a knee airbag that is inflated and deployed by the gas; an airbag door that is provided in the column cover, and that is opened when the airbag door receives the inflation pressure of the knee airbag; a collision prediction device that predicts that a vehicle will have a collision with a collision object; and a control device that operates the telescopic mechanism so that each of the column cover and the airbag module is moved rearward to a predetermined position, when the collision prediction device predicts that the vehicle will have a collision with the collision object.
