<P>PROBLEM TO BE SOLVED: To provide a knee-protecting airbag apparatus capable of suppressing the opening resistance of an airbag cover covering a stored airbag, and securing the prompt deploying/expanding of the airbag from a storage part without unnecessarily improving the inner pressure of the airbag in an expansion early stage. <P>SOLUTION: The knee-protecting airbag apparatus M1 is mounted to a column cover 16 covering a steering column 3. The airbag apparatus M1 comprises the airbag folded and stored, and arranged on the front side of knees of a driver while being deployed and expanded by making an expansion gas flow therein upon actuation; and the airbag cover 33 pushed by the expanding airbag to open doors 34, 38, and forming a projecting opening 22 of the airbag 45 at the column cover 16. The airbag cover 33 is arranged at the column cover 16 while having a separating surface SP previously separated to the peripheral edge of the projecting opening 22 from a state before opening at a part of the outer peripheral edge of the doors so as to suppress resistance when the doors portions are opened. <P>COPYRIGHT: (C)2008,JPO&INPIT |
