  • Patent number: 9663063
    Abstract: 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.

  • Patent number: 9195257
    Abstract: 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 insulator 14 includes a first flange portion 14a provided between a stopper 13 and an elastic body 15, and a second flange portion 14b provided between a coil spring 17 and the elastic body 15. The elastic body 15 includes a first diameter-increased portion 15a increased in diameter to be contactable with the first flange portion 14a, and a second diameter-increased portion 15b increased in diameter to be contactable with the second flange portion 14b. A contact surface of the first flange portion 14a with the first diameter-increased portion 15a has a plurality of linear projections 14c arranged in a substantially radial fashion.

  • Patent number: 8757715
    Abstract: 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.

  • Patent number: 8733203
    Abstract: 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 (11), a second horn plate (21), guide pins (12), stoppers (13), bushes (14), elastic members (15), and coil springs (16); the bushes (14) are divided into first bushes (141) which have first flanges (14a), openings (14b), columnar parts (14c); and recessed parts (14d), and second bushes (142) which have second flanges (14e), openings (140, and casings (14h); and the columnar parts (14c) are configured so as to be in contact with the second flanges (14e).

  • Patent number: 8286766
    Abstract: A slider 24 is supported on a holder 19 of a steering wheel 11 via a coil spring 25 so as to be movable in a direction of an axis while an air bag module 20 is supported on a slider 24 via a damper spring 26 so as to be movable in a direction perpendicular to the axis. Since the coil spring 25 does not affect vibration of the air bag module 20 in the direction perpendicular to the axis, it is possible to set a spring constant of the coil spring 25 at a value appropriate for the operation of a horn switch 37, and to set a spring constant of the damper spring 26 at a value appropriate for the operation of the dynamic damper. As a result, it is possible to effectively reduce the vibration of the steering wheel 11 in the direction perpendicular to the axis with the dynamic damper without affecting the operability of the horn switch 37.
