AIR BAG DEVICE FOR KNEE PROTECTION

摘要

An air bag device for knee protection (M1), wherein an air bag (26) covers the substantial lower surface (9a) of a column cover (9) projected to an operator side to minimize the volume thereof without deteriorating the protection of the knee of the operator so as to reduce a time required for the air bag to complete the development and inflation, and the shape of the air bag after completing the inflation is formed generally in a plate shape capable of covering at least the lower surface of the column cover, whereby, even if the knee of the operator is close to the column cover in the state of the operator depressing a brake pedal, the developed and inflated air bag can be disposed smoothly in a small space between the knee of the operator and the lower surface of the column cover without being interferred with the knee of the operator, and thus the knee of the operator can be protected accurately by rapidly developing and inflating the air bag in the small space between the column cover and the knee of the operator.
