An airbag module that serves as a damper mass mounted to the steering wheel surrounding the center of steering of the steering wheel via vibration damping parts, the vehicle steering wheel structure damping steering wheel vibration, wherein the vibration damping parts includes at least a first vibration damping part positioned upward from the center of steering and a second vibration damping part positioned downward from the center of steering with reference to a neutral position of the steering wheel and the spring constant or elastic modulus of the first vibration damping part is set lower than the spring constant or elastic modulus of the second vibration damping part.

[Problem] To enable an airbag module to be assuredly assembled to a cored bar. [Resolution Means] The present invention is applied to a steering wheel including: a cored bar member; and an airbag module which houses an airbag cushion and an inflator and is coupled to the cored bar member via a coupling pin, wherein the steering wheel employs a configuration in which the coupling pin extends from the airbag module side to the cored bar member side. The steering wheel according to the present invention includes: a coil spring arranged outside the coupling pin; and a support member supporting the upper end of the coil spring at a peripheral part of the coupling pin. Moreover, the support member includes a hook which includes: a support surface protruding in the direction vertical to the shaft of the coupling pin in order to support the upper end part of the coil spring; and a side extending from this support surface towards the lower side of the coupling pin. In addition, the coil spring is configured so as not to interfere with the side of the hook.

A driver airbag device may include: a housing having an airbag module mounted therein, and configured to induce a horn operation while moved backward by an external force; a boss part formed on the housing; a steering wheel part mounted in the housing, configured to sense a horn operation and perform a steering operation, and having the boss part installed therethrough; and a movement prevention part mounted on the boss part, and configured to prevent movement of the housing connected to the boss part.

An airbag apparatus attachment mechanism includes a holder, a supporting member, an urging member, and a functional member. The holder is fastened to a metal core with a fastening member. The supporting member protrudes further forward than an airbag apparatus and is inserted into the holder. The urging member urges the airbag apparatus rearward. The functional member is attached to a part of the supporting member that is inserted in the holder. The functional member includes a spring portion that is thinner than a gap between the supporting member and the holder. The spring portion is disposed in the gap. The functional member is configured such that the spring portion is elastically deformed in a radial direction of the supporting member due to vibration of the airbag apparatus, thereby suppressing the vibration.

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.

A driver seat airbag including a horn plate seated on a steering wheel armature and provided with a plurality of restraint holes; holders disposed in the plurality of restraint holes; restraint clips installed in the plurality of holders to be elastically deformable; a mounting plate seated on the horn plate; and hooks provided to protrude from the mounting plate to correspond to the plurality of restraint holes, inserted into the plurality of restraint holes, and hooked on and restrained by the restraint clips.

Provided is a driver airbag device for a vehicle deploying to the front of a steering wheel while avoiding an obstacle in the rear of the steering wheel on which the obstacle is positioned at a center portion, the driver airbag device comprising an airbag cushion deploying to the front of the steering wheel by passing between the obstacle and the steering wheel when gas is injected inside; a gas injection device positioned under the airbag cushion to inject gas into the airbag cushion through a gas outlet; and a diffuser positioned inside the airbag cushion and configured to partially or entirely cover the gas outlet from above to deploy by the gas injected through the gas outlet and induce the gas to flow to an opening opened toward the front of the steering wheel

A damper structure provided in a steering wheel of a vehicle to be able to achieve an improved effect of reducing vibration in a low frequency region and structurally prevent noise generation. The damper structure includes a plate member which faces the steering wheel and to which an airbag module is to be attached, an insulator attached to the plate member, a connector inserted into the insulator and having one end fixed to the steering wheel to be oscillated by vibration of the steering wheel, an elastic member surrounding the connector in the insulator, a ring provided with the elastic member to transmit the oscillation of the connector to the elastic member, a stopper provided around another end of the connector to face the elastic member, and a coil spring which brings the elastic member of the insulator into pressure contact with the stopper.

A horn plate assembly for a vehicle includes: a horn plate having a plurality of fastening holes; and fasteners fastened to a hub of a steering wheel through the fastening holes. Seating grooves having stepped cross-sections to the fastening holes are formed at the fastening holes, and portions of the fasteners are seated in the seating grooves when the fasteners are fastened to the hub of the steering wheel.

A driver airbag mounting verification system comprises a portion of an electrical circuit configured to connect a vehicle horn to a vehicle-mounted power source. The portion of the electrical circuit includes two electrical contacts resiliently biased into contact with one another so as to complete electrically the electrical circuit and thereby to actuate the vehicle horn. The portion of the electrical circuit including both of the electrical contacts is mounted on one of a driver airbag module and a vehicle steering wheel. At least one of the electrical contacts is mounted such that said at least one of the electrical contacts is moved and held out of contact with the other of the electrical contacts when the driver airbag module is securely mounted on the vehicle steering wheel.
