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: An airbag device installed in a steering wheel of a vehicle and includes: a gas generator that is secured to the steering wheel and generates expansion gas; and an airbag cushion that is expanded and deployed by the expansion gas toward the occupant side. The airbag cushion includes an occupant side panel that faces an occupant when expanded and deployed, a steering side panel that is opposite the occupant side panel, and a side panel that connects both panels at the outer edge of the occupant side panel and the steering side panel. A recessed part is formed near the center of the occupant side panel with the airbag cushion in an expanded and deployed state. A substantially flat part that comes into contact with the face of the occupant is formed in an area above the recessed part of the occupant side panel.

Abstract: A driver seat airbag apparatus includes a steering wheel and an airbag module. The steering wheel has a central hub and a rim. The rim has a shape in which a portion of the upper portion of the hub is omitted. The hub includes: a module housing part which houses the airbag module; and a cover which covers the module housing and is cleavable at the expansion pressure of the cushion. The cover includes cover doors which open at the expansion pressure of the cushion. When the cover is cleaved, the cover doors are open in the right and left diagonal upward directions when viewed from the center of the hub, while a space portion without the cover doors is formed in the direction directly above the center of the hub when viewed from the center of the hub.

Abstract: This invention provides a vehicle steering wheel vibration reducing structure capable of effectively damping induced vibration generated in the steering wheel and contributing to vibration reduction in both low frequency bands and high frequency bands.
A vehicle steering wheel vibration reducing structure, where the vehicle steering wheel structure is such that an airbag module-2, which serves as a damper mass, is attached to the steering wheel via vibration damping parts 19 to damp vibrations of the steering wheel, and where the airbag module is formed such that the upper region above the center of steering of the steering wheel is lighter than the lower region, with reference to a neutral position of the steering wheel.

Abstract: An airbag device that is stowed in the instrument panel of a vehicle in order to protect an occupant in a passenger seat and includes an inflator for generating expansion gas along with an airbag that inflates and deploys toward the occupant side via gas released from the inflator. The airbag is connected to the inflator and includes a main chamber positioned in front of the occupant properly seated during deployment and a sub chamber connected to at least one side of the main chamber. An inner vent through which gas flows, is formed at a boundary portion of the main chamber and the sub chamber. Furthermore, a check valve for opening and closing the inner vent is provided.

Abstract: A vehicular airbag device that comprises: an inflator; and an airbag cushion that inflates and deploys between a steering wheel and an occupant. The airbag cushion includes: an occupant-side panel that deploys to the occupant side and restrains the occupant; a vehicle-side panel that is disposed on the opposite side to the occupant-side panel; and side panels that connect the occupant-side panel and the vehicle-side panel and constitute the side surfaces of the airbag cushion. The side panels comprise a plurality of subpanels. A base material weft that constitutes a central section E1 of the sub-panels extends in a virtual plane S2 that follows the occupant side of the rim of a steering wheel when the airbag cushion is inflated and deployed.
