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 steering wheel includes a steering wheel body, a retainer supported by the steering wheel body and provided with a hole, an airbag apparatus fixed to the retainer, and a damper apparatus disposed between the steering wheel body and the retainer. One end of the damper apparatus is fixed to the retainer by being fitted into the hole provided in the retainer. The damper apparatus includes an elastic body. The elastic body extends in a circumferential direction along an inner edge of the hole and is formed so as to fit the inner edge of the hole. The inner edge of the hole of the retainer is bent such that the end of the inner edge does not contact the elastic body.

A frequency-tuned vibration damper assembly includes a horn plate connected to a vibrating surface of a steering wheel structure at a first interface via a plurality of first elastic damper elements so as to be movable in relation to the vibrating surface. A mass supported by the plate is movable in relation to the plate on an opposite front side of the plate. Elastic buffer elements are provided at a second interface between the plate and the mass. The stiffness of the elastic buffer elements is selected such that they form second elastic damper elements which together with the first elastic damper elements and the mass form a frequency-tuned dampened mass-spring system having two damping interfaces and being frequency-tuned to vibrations of said vibrating surface.

PROBLEM Provided is a vehicle steering wheel device enabling miniaturizing an airbag module and also a miniaturized horn pad portion while ensuring a damping effect comparable to a conventional damping effect.

RESOLUTION MEANS Each damper 11 has a straight pin, a grip 19 provided at a first end is engaged to a central cored bar 8 through rotate operation around the pin axis, and a connecting tip end part 12a that connects to the module housing 6 is provided at the other end. A plurality of insertion holes through which the connecting tip end part is inserted are arranged in the module housing surrounding the outer edge of the inflator 7, and the connecting tip end part is formed with a constricted portion having an outer diameter smaller than the hole diameter of the insertion hole, and the connecting tip end part is connected to the module housing via a set spring supported by the module housing so as to engage the constriction.

The invention relates to a device (18) for securing a gas generator (14) in an oscillating manner as a vibration-absorbing mass inside an airbag module (10). The invention is characterized m that a securing ring is provided for securing to the gas generator (14), said ring being open at least in sections in the radial direction by a continuous, radially outwardly directed annular gap and is provided with at least one axially oriented damping member.

A vehicle steering wheel (100) comprising: a frame (10) supporting at least a frame cladding portion (20) visible to an occupant of the vehicle, and a module housing (30) comprising a housing wall (31) integral with the frame cladding portion (20), a safety module (40) at least partially arranged in the module housing (30) and comprising a module cladding portion (50) visible to the vehicle occupant, characterized: in that the safety module (40) comprises at least one bearing surface (411), and in that, during a mounting movement of the safety module (40) in the module housing (30), the housing wall (31) is placed in a reference position by the bearing surface (411), so that the frame cladding portion (20) has a predefined fit with the module cladding portion (50).

A steering wheel includes a steering wheel body, a retainer supported by the steering wheel body and provided with a hole, an airbag apparatus fixed to the retainer, and a damper apparatus disposed between the steering wheel body and the retainer. One end of the damper apparatus is fixed to the retainer by being fitted into the hole provided in the retainer. The damper apparatus includes an elastic body. The elastic body extends in a circumferential direction along an inner edge of the hole and is formed so as to fit the inner edge of the hole. The inner edge of the hole of the retainer is bent such that the end of the inner edge does not contact the elastic body.

The invention relates to an airbag module (10) for a vehicle steering wheel (6), comprising a module base (12) for fixed mounting on the vehicle steering wheel (6), which module base has a base opening (14), and a vibration absorber ring (16) for fastening a gas generator (18) to the module base (12) such that said gas generator can vibrate. The vibration absorber ring (16) has a ring axis (A) and a mounting flange (20) for the gas generator (18). The vibration absorber ring (16) has a resilient absorber wall (22), starting from the mounting flange (20), which absorber wall extends in an axial direction toward the module base (12) and extends around the ring axis (A) in the circumferential direction. The vibration absorber ring (16) has a plurality of resilient absorber feet (24) for fastening to the module base (12), which absorber feet extend in the axial direction. The vibration absorber ring (16) is fastened to the module base (12) by means of the absorber feet (24) such that the absorber wall (22) bears against the module base (12) already before activation of the airbag module (10) and acts in an axial direction against the module base (12) and is resiliently deformed.

A steering wheel includes a steering wheel body including at least two insertion openings, and an airbag module including at least two hooks inserted into the insertion openings. The hooks are held by wires so that the airbag module is supported by the steering wheel body. Either the at least two hooks or the at least two insertion holes are provided with adjustment ribs which come into contact with the other ones of the at least two hooks and the at least two openings, thereby regulating the positions of the other ones, so as to receive the weight of the airbag module applied to the steering wheel body. Accordingly, a decrease in positioning performance of the airbag module is prevented, so as to regulate the position of the airbag module in the steering wheel body with high accuracy.

This steering equipment component is retained on a steering wheel main unit (4) by a lock portion when, at the time of its attachment, pushed in the steering wheel main unit (4) by a predetermined stroke or longer. The steering wheel main unit (4) and the steering equipment component are each provided with an energizing portion, and the energizing portions energize a horn circuit (38) through their mutual contact. In attaching the steering equipment component, the energizing portions are configured to be in contact connection to each other until the steering equipment component is pushed in by the predetermined stroke or longer, and the contact connection between the energizing portions is configured to be interrupted when the steering equipment component is pushed in by the predetermined stroke or longer.
