1. An air bag apparatus to be mounted in a vehicle in an immovable state, said air bag apparatus comprising:

  • a stationary pad mounted with a steering wheel, said pad being stationary relative to a turning movement of said steering wheel;

    a heteromorphic bag accommodated in a folded state in said stationary pad;

    an inflator having means for jetting gas into said bag when said vehicle is subjected to sudden deceleration, said inflator being mounted on said stationary pad in said bag; and

    a restricting member formed by a soft material having first and second ends thereof mounted on a surface of an inner circumference of said bag so as to restrict an expanding height of said bag which tends to expand in the form of a sphere relative to an axis of said inflator toward an occupant of said vehicle by said gas jetting upon sudden deceleration of said vehicle, wherein a mounting position of said first end of said restricting member is fixed to a lower side of said inflator, and a mounting position of said second end of said restricting member is fixed to a position on an inner surface of said bag displaced a predetermined length from a center of a front face of said bag, whereby said bag is restricted to form a flat sphere offset from said axis or said inflator.
