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.

The invention relates to a device for removably mounting an airbag module on a steering wheel, the mounting device comprises a mounting portion of a resilient ring for forming, in a locking position of the ring, an element for holding at least one hook on the other of the module or the steering wheel, the resilient ring having an unlocking position in which the mounting portion of the ring is no longer in the zone of interaction with the at least one hook, the device further comprises an element for releasing the ring, connected to one of the module or the steering wheel and arranged so as to move the ring during a movement for extracting the module such that the ring is placed back from the locking position.

A steering apparatus assembly for a motor vehicle, having a steering axis, about which the steering apparatus assembly can rotate in the installed condition is disclosed. The steering apparatus assembly comprises a first assembly element and a second assembly element. The two assembly elements are connected to one another by a first joint and a second joint. The first joint comprises a resilient locking element, which can be deflected in a direction transverse to the steering axis to disengage the first joint. The second joint can be disengaged by an axial load acting on the assembly elements away from one another. A wedge is provided which has a wedge length transverse to the steering axis and a variable wedge height in the direction of the steering axis. The wedge length, the wedge height and an angle of inclination of the wedge are matched to one another such that both the first joint and the second joint of the assembly elements can be undone by a linear movement of the wedge in the longitudinal direction of the wedge.

Proposed is an apparatus for connecting a steering wheel and an airbag module. The airbag module is mounted on a front portion of the steering wheel. A coupling hole extends through the steering wheel in a front-rear direction. A hook extends from the airbag module through the coupling hole to protrude from a rear surface of the steering wheel. A bend on a distal end of the hook is bent in a direction intersecting a longitudinal direction of the hook. A fixing clip blocks the movement of the hook in a forward direction of the steering wheel, with first end being fixed to the steering wheel, and the second end being caught by the bend of the hook. A fixing recess is indented into the steering wheel, thereby allowing the second end of the fixing clip to move in the forward direction of the steering wheel.

Provided is a steering wheel including a dynamic damper mechanism which does not easily deteriorate over time, in which a resonance frequency to be damped does not easily change. An attaching structure for attaching an airbag device to a steering wheel incudes: a tubular guide member (51) passing through an opening of a fixing plate (25) of the airbag device; a hook (70, 80) engaging with a lock spring (53); a hollow holding member (67) fixed to a main body part (110) of the steering wheel and holding a base end portion (71) of the hook while restricting the base end portion (71) from moving toward a tip end portion (75) of the hook; and a return spring (61), and the base end portion (71) has a bottom portion being a convex spherical shape.

The disclosure is directed to a steering device assembly for positioning and fastening an airbag module on a steering device of a motor vehicle. The steering device assembly comprises a first positioning body having a detent lever, a carrier, a spring element, and a second positioning body. The detent lever comprises a first leg and a second leg connected to the first leg at one leg end the detent lever is mounted for pivoting between an initial position and a final assembly position on the carrier. The spring element loads the detent lever into the final assembly position. Each leg extends to an opposite free leg end at a specified angle. The second positioning body has a stop for the free leg end of the first leg for pivoting the detent lever from the initial position into the final assembly position and a detent contour for locking with the free leg end of the second leg in the final assembly position of the detent lever. A method for installing an airbag module on a steering device of a motor vehicle by the steering device assembly.

The invention relates to a coupling device (16) for mounting an airbag module (14) to be oscillating on a steering wheel structure (12) of a vehicle steering wheel (10), comprising a mounting member (18) which includes, relative to a steering wheel axis (A), an axial bottom side (20) which in the assembled state of the vehicle steering wheel (10) faces the steering wheel structure (12) as well as an opposite axial top side (22) which in the assembled state of the vehicle steering wheel (10) faces the airbag module (14), a contact face (24) for a damping element (26) provided on the axial bottom side (20) for oscillating coupling of the mounting member (18) to the steering wheel structure (12), and comprising a locking element (28) disposed on the top side (22) of the mounting member (18) for locking with the prefabricated airbag module (14), wherein the locking element (28) is configured so that the airbag module (14) can be coupled to the mounting member (18) by a locking connection substantially in an axially fixed manner or in an axially restrictedly movable manner.

Proposed is an apparatus for coupling an airbag module to a steering wheel. A coupling open area extends completely through a steering wheel in a forward-backward direction. A hook extends from a rear portion of an airbag module to behind the steering wheel, and includes a bent portion provided on a distal end to be bent in a direction intersecting a longitudinal direction of the hook. A fixing clip is disposed on a rear portion of the steering wheel and fixed to the steering wheel, with an end of the fixing clip being caught by and coupled to the bent portion of the hook to stop movement of the hook forward of the steering wheel. A catching protrusion protrudes from the rear portion of the steering wheel to catch the end of the fixing clip and stop movement of the fixing clip when the hook is decoupled.
