A steering wheel includes a functional device and a control device, which is electrically connected to the functional device. The functional device includes a functional case, which constitutes a housing of the functional device. The control device includes a control case, which constitutes a housing of the control device. A first connector is partially exposed to an outside of the functional case. A second connector is partially exposed to an outside of the control case. The first connector is coupled to the second connector, so that the functional device is electrically connected to the control device without a harness between the functional case and the control case.

Steering wheel

A steering wheel includes a metal core earthed to a body of a vehicle, an airbag device, an insulator, and a connector. The airbag device includes a bag holder supported by the metal core, wherein the bag holder forms part of a positive electric path connected to a horn device, an airbag coupled to the bag holder by a fastener, and an inflator including a circumferential portion that forms a flange, wherein the flange of the inflator is coupled by the fastener to the bag holder. The insulator insulates the bag holder from at least the flange and the fastener among elements of the airbag device. The connector electrically connects at least the flange, among the flange and the fastener, to the metal core.

A completely folded body of an airbag includes: a front-side folded portion; and a rear-side folded portion, wherein: the front-side folded portion has such a folded shape that a tip separated longitudinally from the mounting portion of the front overlapped portion is stored in a dent portion, in which a front side is open and a rear side is dented, between a mounting-portion-side folded portion near the mounting portion and a central folded portion between the tip and the mounting-portion-side folded portion; the tip of the front overlapped portion includes a leading edge separate longitudinally the farthest from the mounting portion, and a tip root-side portion connected to the leading edge; and the leading edge is provided on an upper side of the tip root-side portion in the front-side folded portion to be inverted rearward to a central side of the mounting portion.

Completely folded body of airbag and folding method of the same

An air bag system includes: a pad including a ceiling wall portion which covers an air bag and a side wall portion which extends into a cylindrical shape; a mounting base which holds the pad and holds the air bag by causing an annular retainer; and switch members which make up a horn switch mechanism so that the mounting base is mounted on a steering wheel main body, wherein: the switch members are provided below the air bag; and movable-side members are provided so that a portion at a side facing the inlet opening on an upper side thereof is brought into abutment with the retainer via a circumferential edge of the inlet opening of the air bag and a portion at a side thereof is brought into abutment with a lower surface of the side wall portion of the pad.

Air bag system

A steering wheel includes: a boss part; a ring part that is located at an outer circumferential side of the boss part; a plurality of spoke parts that connect the boss part and the ring part; and a core including: a core boss part; a core ring part that is located at an outer circumferential side of the core boss part; and core spoke parts that connect the core boss part and the core ring part, wherein: the plurality of spoke parts include true spoke parts having the core spoke parts, and a pseudo spoke part that does not have the core spoke parts; and the pseudo spoke part is mounted on the core ring part, and includes a separate retaining member that retains a shape of the pseudo spoke part.

Cover of airbag device for automobile

An airbag cover includes a ceiling wall portion provided on a steering wheel, and covered an airbag. The ceiling wall portion has an attaching door portion and a non-attaching door portion opened to the left and the right, causing a predetermined fracture portion to facture by the inflating airbag. The attaching door portion has an ornament retained on an attaching seat. In the predetermined fracture portion, the common portion positioned at the center of the right and left door portions has a bypass portion on the circumference of the attaching seat. The attaching door portion is slightly opened toward the rear.

Steering wheel airbag cover

An elastic wire which is linearly moved in an assembling direction parallel with an orthogonal surface perpendicular to an axial line of a steering shaft and thus assembled to a core member includes an attaching part that is attached to a core member and an engaging part that is engaged into a pin in a through-hole. The core member is provided with a surface restraint part that permits the attaching part to linearly move in the assembling direction and restrains the engaged attaching part from moving in a direction parallel with the orthogonal surface. The surface restraint part includes a restraining protrusion that permits the bent partof the attaching partto surmount the restraining protrusion as the elastic wire is linearly moved and restrains the bent part having surmounted the restraining protrusion from moving in an opposite direction to the assembling direction.

Steering wheel having airbag apparatus attached thereto

In an airbag-equipped steering wheel, a plurality of horn switch mechanisms assembled to a bag holder each have a securing pin, which is inserted into a corresponding one of through holes formed in a metal core. A clip is engaged with a locking groove of each securing pin, so that each horn switch mechanism is fastened to the metal core. The through holes include one or more normal through holes that restrict inclination of the corresponding securing pins, and a special through hole that has an inclination permitting portion. The inclination permitting portion permits the corresponding securing pin to be inclined about the corresponding clipserving as a fulcrum. In the special through hole, the securing pin is permitted to be inclined about the clip serving as a fulcrum only when the clips are disengaged from the securing pin in all the normal through holes.
