Claims
- 1. An air bag apparatus to be mounted in a vehicle in an immovable state, said air bag apparatus comprising:
- a stationary pad;
- means for holding said stationary pad immovable during turning of a steering wheel, said means comprising a planetary gear structure that includes:
- a fixed gear having a training portion formed continuously over an outer peripheral surface of said fixed gear,
- a sun gear having a training portion formed continuously over an outer peripheral surface of said sun gear and wherein said sun gear is rotatable relative to a steering shaft and said stationary pad is mounted on said sun gear,
- a plurality of planetary gears coupled with said steering wheel, wherein said planetary gears include a training portion formed continuously over an outer peripheral surface of said planetary gears, and
- a timing belt cooperating with said training portion of said sun gear, said fixed gear and said planetary gears respectively;
- a heteromorphic bag accommodated in a folded state in said stationary pad;
- an inflator communicating with an interior of said bag, said inflator comprising a means for generating a gas when said vehicle is subjected to sudden deceleration,
- a means for jetting said gas into said interior of said bag, and
- a means for coupling said inflator and said bag and securing said jetting means within said bag; and
- a plurality of restricting members formed by a soft material, both ends of each of said plurality of restricting members mounted on a surface of an inner circumference of said bag so as to restrict the expanding height of said bag which tends to expand in the form of a sphere towards the side of an occupant by said gas jetting upon sudden deceleration of said vehicle, wherein,
- said bag in an inflated state is formed so that the portion corresponding to a portion other than the head of an occupant is smaller as compared with the portion corresponding to the head of said occupant, and
- said portion corresponding to a portion other than the head of said occupant is bounded by a lower portion of said bag formed into a substantially straight line.
- 2. The air bag apparatus according to claim 1, wherein said bag is formed so that said portion corresponding to a portion other than the head of said occupant is shaped in a different form from the portion corresponding to said head of said occupant.
- 3. An air bag apparatus disposed in a vehicle in an immovable state, wherein a bag is inflated in a state of sudden deceleration of said vehicle to protect an occupant by being interposed between a vehicle body and said occupant, said air bag apparatus comprising:
- a stationary pad;
- means for holding said stationary pad immovable during turning of a steering wheel, said means comprising a planetary gear structure including a fixed gear having a training portion formed continuously over an outer peripheral surface of said fixed gear,
- a sun gear having a training portion formed continuously over an outer peripheral surface of said sun gear and wherein said sun gear is rotatable relative to a steering shaft and said stationary pad is mounted on said sun gear,
- a plurality of planetary gears coupled with said steering wheel, wherein said planetary gears include a training portion formed continuously over an outer peripheral surface of said planetary gears, and
- a timing belt cooperating with said training portion of said sun gear, said fixed gear and said planetary gears respectively; and
- a heteromorphic bag accommodated in a folded state in said stationary pad, said bag including, in its inflated state, a portion corresponding to the head of said occupant and a portion corresponding to a portion other than said head of said occupant, wherein said bag in said inflated state is formed so that said portion corresponding to a portion other than the head of said occupant is made smaller as compared with said portion corresponding to the head of said occupant, wherein
- said portion corresponding to a portion other than the head of said occupant is bounded by a lower portion of said bag formed into a substantially straight line.
- 4. The air bag apparatus according to claim 3 wherein said bag is formed so that said portion corresponding to a portion other than the head of said occupant is shaped in a different form from said portion corresponding to the head of said occupant.
