Definitions
- the present invention relates to a pad structure of a steering wheel in which a horn switch is operated by pressing a pad attached to a steering wheel against a biasing force of an elastic member.
- an airbag device and a pad for storing the airbag device are configured as a single module, and this module is connected to a steering ring via an elastic body. Supported by wheels.
- a horn switch is provided between the module and the steering wheel. The horn switch is pressed by pressing the pad against the urging force of the elastic body to move the pad and the airbag device. Is activated.
- the elastic body is configured to support not only the pad but also the airbag device, the spring constant of the elastic body is increased. It is necessary to urge the pad and airbag device to the occupant side. Therefore, when operating the horn switch, it is necessary to press the pad with a large pressing force, and the horn switch cannot be operated smoothly.
- a horn switch was provided on the rim or spoke of the steering wheel, and the horn was operated by pressing the horn switch. Although there are some, there is a problem that it is difficult to operate the horn switch when rotating the steering wheel. Disclosure of the invention
- the present invention has been made in view of the above circumstances, and has as its object to obtain a steering wheel pad structure capable of smoothly operating a horn switch.
- a pad for storing an energy absorbing member for absorbing an occupant's inertial movement force is supported by a steering wheel via a biasing member, and the pad is attached to the biasing member.
- an energy absorbing member that absorbs an occupant's inertial movement is attached to the steering wheel separately from the pad. That is, in the present invention, the urging member (for example, the elastic body) does not need to support the energy absorbing member, and the pad and the energy absorbing member are compared with a case where the pad and the energy absorbing member are constituted by a single module.
- the spring constant of the elastic body can be reduced, and the force required to operate the horn switch can be reduced.
- the steering wheel pad structure according to the present invention has an excellent effect that the operation of the horn switch can be performed smoothly.
- FIG. 1 shows a pad structure of a steering wheel according to an embodiment of the present invention, and is a view taken along line 2-2 in FIG. 2 in a state where an airbag device is mounted.
- FIG. 2 is a plan view showing the steering wheel before the airbag device is attached according to the embodiment of the present invention.
- a steering pad 12 is disposed at the center of the steering wheel 10. Between the steering pad 12 and the steering wheel 10, an airbag device 3 as an energy absorbing member shown in FIG. 0 is arranged. Steering pad 12 is fixed to mounting plate 16 which is fastened to contact plate 14 by bolts (not shown).
- a pair of contact plates 14 are provided on the steering pad 12 side of the hub 11 of the steering wheel 10 at intervals in the vertical direction in FIG.
- through-holes 14 A are formed at both ends of each contact plate 14 in the longitudinal direction (horizontal direction in FIG. 2).
- a shaft 1 is formed in each through-hole 14 A.
- the middle part of 8 is inserted.
- a bush 20 is fixed to an intermediate portion of the shaft 18, and the contact plate 14 is guided by the outer periphery of the bush 20 in the vertical direction in FIG.
- a female screw 18 A is formed at the lower end of the shaft 18, and the female screw 18 A is screwed to the hub 11.
- a flange 2OA is formed at the upper end of the bush 20, and the upward movement of the contact plate 14 in FIG. 1 is restricted by the flange 20A. I have.
- Each contact plate 14 is provided with a moving contact 22 near each of a pair of through holes 14 A on the surface opposite to the steering pad 12, and each moving contact 22 is attached to the contact plate 14.
- the fixed contacts 24 corresponding to 22 are fixed to the hub 11 of the steering wheel 10.
- the movable contact 22 and the fixed contact 24 constitute a horn switch.
- a compression coil spring 40 is provided between the periphery of the pair of through holes 14 A on the surface of the contact plate 14 opposite to the steering pad 12 and the hub 11 of the steering wheel 10.
- the contact plate 14 is always urged in the upper part of FIG. 1, that is, the moving contact 22 is separated from the fixed contact 24 by passing through the middle part of the contact 18. ing. Occupant urges compression coil spring 40
- the contact plate 14 When the steering pad 12 is pushed downward by the force, the contact plate 14 also moves downward, and the movable contact 22 and the fixed contact 24 come into contact, and the horn switch is turned on.
- the contact plate 14 together with the steering pad 12 is moved upward in FIG. 1 by the biasing force of the compression coil spring 40, and the movable contact 22 is fixed.
- the Horn switch is turned off.
- the airbag device 30 includes a base plate 34.
- the left and right ends of the base plate 34 in FIG. 1 are bent downward at right angles to form mounting portions 34A.
- 34 A is fixed to each of a pair of fixing plates 38 fixed to the hub 11 of the steering wheel 10 by rivets 40.
- the base plate 34 has an inflation overnight 36 and a bag 32 attached thereto.
- the airbag device 30 is separated from the steering pad 12, and therefore, the compression coil spring 40 is not subjected to the load of the airbag device 30, so that the compression coil spring 40 is compressed accordingly.
- the spring constant of the coil spring 40 can be reduced. Therefore, a large force is not required to press the steering pad 12 and the horn switch can be operated smoothly.
- the inflation overnight 36 has a substantially columnar shape, and its occupant side half passes through a circular hole (not shown) formed in the center of the base plate 34.
- a rectangular flange 36A is formed at an intermediate portion of the inflation portion 36 in the radial direction of the inflation portion 36.
- the inflation overnight 36 is fixed to the surface of the base plate 34 on the side opposite to the occupant by bolts or the like (not shown) through the flange 36A.
- a plurality of gas holes are formed on the occupant side peripheral surface of the inflation overnight.
- a starting device (not shown) that operates at the time of sudden deceleration of the vehicle is disposed on the shaft of the inflation heater 36. Further, on the outer periphery of the starting device, a primer (not shown), a detonator, A gas generant is contained. Therefore, when the vehicle suddenly decelerates, the starting device operates to ignite the detonator, and the gas generating agent is burned through the explosive and burns out. An amount of gas is generated, and this gas flows into the bag 32 from the gas hole. As a result, the bag 32 expands, the steering pad 12 is broken, and the bag 32 is interposed between the steering wheel 10 and the occupant.
- the shaft 18 to which the bush 20 is fixed is inserted through the through hole 14 A of the contact plate 14, and the shaft 18 is further inserted with the compression coil spring 40 inserted through the shaft 18. Screw into hub 1 1.
- the steering wheel pad 12 is fixed to the contact spring 14 via the mounting plate 16.
- the contact plate 14 also moves downward and the horn switch is turned on, and the pressing of the steering wheel 10 is released.
- the contact plate 14 is returned to the original position by the urging force of the compression coil spring 40, and the horn switch is turned off.
- the airbag device 30 is not connected to the steering pad 12, and the compression coil spring 40 does not receive the load of the airbag device 30.
- the spring constant of the compression coil spring 40 can be reduced. Therefore, a large force is not required to press the steering pad 12 and the horn switch can be operated smoothly.
- the airbag device 30 is provided as an example of the energy absorbing member between the steering wheel 10 and the steering pad 12 has been described.
- a cushion material for absorbing the occupant's inertial movement force may be fixed to the base plate 34.
- the spring constant of the compression coil spring 40 can be reduced similarly to the above embodiment, and the steering pad 12 is reduced. No large force is required when pressing, and the operation of the horn switch can be performed smoothly.
