A knee protection airbag for protecting the knees of a vehicular occupant. The airbag is inflated from a storage position to a deployed position to substantially fill a space between the knees of the occupant when seated on a front seat and an instrument panel. By filling the space between the knees and the instrument panel, injury to the knees, and other body parts, is prevented. Inflation of the airbag is caused by a determination by a crash sensor system of a pending or actual crash involving the vehicle and may include an anticipatory crash sensor which forecasts a crash between the vehicle and another object prior to impact of the vehicle by the other object. In this manner, the airbag is inflated prior to the crash.

A knee protecting airbag device (M1), wherein an airbag (26) covers the substantial lower surface (9a) of a column cover (9) protruded to a driver side. Therefore, the airbag is minimized in the capacity without deteriorating the protection of the knee of the driver. As a result, it is possible to shorten the time period required for the airbag to complete the expansion and inflation. The airbag has a generally plate shape capable of covering at least the lower surface of the column cover when it completes the inflation. Even if the knee of the driver comes close to the column cover when the driver depresses a brake pedal or the like, the airbag being expanded and inflated is smoothly arranged in a narrow space between the knee of the driver and the column cover lower surface without interfering with the knee of the driver. With the knee protecting airbag device according to the present invention, therefore, the airbag is rapidly expanded and inflated in the narrow space between the column cover and the knee of the driver thereby to protect the knee of the driver properly.
