Abstract: A driver seat airbag device restrains an occupant seated in a driver seat of a vehicle, and includes, a chest protecting cushion that expands and deploys behind a yoke steering wheel; and a head protecting cushion that expands and deploys adjacent to and above the chest protecting cushion. The head protecting cushion extends from an upper portion of the chest protecting cushion to an upper surface of an instrument panel when expanded and deployed, and contacts and restrains the head of the occupant from the front.

Abstract: An airbag device for a driver's seat is provided with a variant steering wheel, and an airbag module. The variant steering wheel has a module mounting surface and a cover member. When the cover member receives the expansion pressure of a cushion, a cover door opens. The airbag module includes a cloth member that is put on the cushion. A front end side of the cloth member is connected to an inflator, and a rear end is a free end. The airbag module is in a state in which the cushion is in a stored state, the cloth member is put over the cover member side of the cushion, and the cloth member is held between the cover member and the cushion in the stored state.

Abstract: Problem: To provide a damper mechanism of a steering wheel and a steering wheel apparatus for a vehicle in which it is possible to ensure a damping effect comparable to that of the known art and to decrease an airbag module in size so as to achieve a reduction in cost.
Solution: A damper mechanism of a steering wheel includes: two damper units 11 that are provided between a steering wheel 1 and an airbag module 2 functioning as a damper mass and damp vibration of the steering wheel; and an engaging mechanism (hook of a plate-shaped damper 18) that is provided in parallel with the damper unit, between the steering wheel and the airbag module, and holds the steering wheel and the airbag module in a relatively displaceable manner.

Abstract: An airbag includes first and second inner tethers, first and second vent holes formed on left and right sides of the airbag, and first and second opening/closing members capable of opening/closing the first and second vent holes. A first opening/closing tether has a first end portion coupled to the first opening/closing member and a second end portion coupled to the first inner tether, and a second opening/closing tether has a first end portion coupled to the second opening/closing member and a second end portion coupled to the second inner tether. When an occupant contacts the airbag, at least one of the first and second inner tethers is deformed to move at least one of the first and second opening/closing tethers toward the corresponding vent hole and cause at least one of the first and second opening/closing members to open the corresponding vent hole.
