Provided is an air bag device such that a tear line can be efficiently cleaved. An air bag device is provided with: an air bag folded in such a manner as to be expandable by gas from an inflator; a packing cloth wrapping the folded air bag; and a pair of front and rear lids that close an air bag housing portion and that are both-opened as the tear line at the center is cleaved upon deployment. The packing cloth includes an opening portion. The opening portion is positioned at substantially the center in the left-right direction of an automobile with respect to the pair of front and rear lids and is offset forwardly of the automobile.

There is provided a steering wheel that can reduce the load applied to an elastic body included in a dynamic damper to lengthen the life of the dynamic damper, and that allows the frequency of the dynamic damper to be adjusted easily. An insulatorincludes a first flange portionprovided between a stopperand an elastic body, and a second flange portionprovided between a coil springand the elastic body. The elastic bodyincludes a first diameter-increased portionincreased in diameter to be contactable with the first flange portion, and a second diameter-increased portionincreased in diameter to be contactable with the second flange portion. A contact surface of the first flange portionwith the first diameter-increased portionhas a plurality of linear projectionsarranged in a substantially radial fashion.

Steering wheel

A steering wheel structure with an airbag module having a horn bracket fixed to a steering wheel, an airbag module having an inflator and serving as a weight, a spring unit installed between the airbag module and the horn bracket and transmitting vibrations of the steering wheel to the airbag module for configuring a dynamic damper. The spring unit including an elastic body that transmits the vibrations and a protector attached to the horn bracket and housing the elastic body therein in an elastically deformable manner.

A vehicle seat of the present invention includes: a seatback frame which has side frame sections on both sides thereof in a seat width direction; a load transmission member which projects toward an outside in the seat width direction from one of the side frame sections and transmits an impact load input from a side of a vehicle body to the seatback frame; and a side airbag device which is provided with an inflator which generates a gas when the impact load is input and a folded bag body to be deployed when the pressure of the gas is received. The inflator is attached to the load transmission member or the side frame section, and the bag body is disposed at a position which is further outside than a gas discharge port of the inflator in the seat width direction and is opposed to a surface facing the vehicle front side of the load transmission member.

Vehicle seat

A steering wheel in which a load exerted on an elastic member constituting a dynamic damper can be reduced, the life of the dynamic damper can be extended, and the assembly operation is readily performed. The steering wheel has a first horn plate (), a second horn plate (), guide pins (), stoppers (), bushes (), elastic members (), and coil springs (); the bushes () are divided into first bushes () which have first flanges (), openings (), columnar parts (); and recessed parts (), and second bushes () which have second flanges (), openings (, and casings (); and the columnar parts () are configured so as to be in contact with the second flanges ().

A slideris supported on a holderof a steering wheelvia a coil springso as to be movable in a direction of an axis while an air bag moduleis supported on a slidervia a damper springso as to be movable in a direction perpendicular to the axis. Since the coil springdoes not affect vibration of the air bag modulein the direction perpendicular to the axis, it is possible to set a spring constant of the coil springat a value appropriate for the operation of a horn switch, and to set a spring constant of the damper springat a value appropriate for the operation of the dynamic damper. As a result, it is possible to effectively reduce the vibration of the steering wheelin the direction perpendicular to the axis with the dynamic damper without affecting the operability of the horn switch

Vibration reducing structure for steering wheel

An automotive air bag device has a panel, a folded bag installed in a deeper portion behind the panel, a cover provided in the panel and a connecting member that connects a vehicle body side with the cover. The air bag is inflated by virtue of a gas pressure to push open the cover provided so that the air bag deploy into a passenger compartment, the cover is mounted in the panel so as to be separated from the panel when the air bag is inflated and the connecting member controls a protrusion of the air bag into a passenger compartment.
