Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a front seat device installed in, for example, an automobile cabin, and particularly relates to a front seat device equipped with at least three
The present invention relates to an improvement in an adjustment mechanism operating section that has two adjustment functions concentrated in one place.

[Technical background of the invention and its problems]

Figure 1 shows the cabin of a conventionally used general automobile, where 1 is a front seat device, and 2 is a front seat device.
is a rear seat device. Both seat devices 1 and 2 are composed of a seat cushion 3 and a seat bag 4. By the way, while the seat back 4 of the rear seat device 2 is fixed to the vehicle body and cannot adjust its posture or height, the seat back 4 of the front seat device 1 is a so-called reclining seat whose posture can be adjusted. It is normal for there to be. Furthermore, recently, in the front seat device 1, not only the front and rear sliding position and height adjustment of the seat cushion 3, but also the
The seat back 4 can be divided into two parts (upper and lower) so that the posture of each part can be adjusted, or the side parts (side supports) of the seat back 4 can be separated and the angle can be adjusted, or the part corresponding to the passenger's waist (lumbar A wide variety of adjustment mechanisms have been developed and put into practical use, including those in which the angle of the support is separate.

It is obvious that if the adjustment levers for operating such an adjustment mechanism are arranged in different positions, it will become difficult to operate, and even if many adjustment levers are concentrated in one place, it will become cumbersome to operate. It is. Therefore, it is generally thought that if the operation part A, which has the adjustment levers of the three adjustment mechanisms gathered in one place, is provided on the side of the seat bag 4, the operation will be easy to remember and the operability will not be impaired.

FIG. 4 is an example of an operating unit A in which first to third adjustment levers 5, 6, and 7 for operating three adjustment mechanisms, respectively, are gathered in one place. . That is, the first adjustment lever 5 for operating the first adjustment mechanism has a first
shafts 8 are connected and extend along the axis. A second adjustment lever 6 for operating the second adjustment mechanism is located on the back side of the first adjustment lever 5, and a second pipe 9 is connected to this second adjustment lever 6. . Also, the second pipe 9
are fitted into the first shaft 8 so as to be rotatable with each other. A third adjustment lever 7 for operating the third adjustment mechanism is located on the back side of the second adjustment lever 6, and a third pipe 10 is connected to this. . third pipe 10

supported by.

By arranging the adjustment levers 5 to 7 of the first to third adjustment mechanisms in one place in this manner, predetermined operations can be performed separately, resulting in extremely high operability.

However, each shaft and pipe 8 to 1
In order to make the shafts and pipes 8 to 10 coaxially fit together and rotatable, the mutual precision between the shafts and the pipes 8 to 10 must be extremely high, which is troublesome to manufacture and difficult to assemble. Furthermore, since all of these components are supported by the bearing member 11, there is a problem that the overall size increases and the dedicated space becomes large.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and its purpose is to reduce manufacturing and assembly precision, reduce costs, and reduce the size of the front seat device. It is intended to provide an operating section for the adjustment mechanism.

[Summary of the idea]

That is, the present invention is provided in a front seat device consisting of a seat cushion and a seat back, and includes at least a first adjustment mechanism to a third adjustment mechanism, such as adjusting the posture of the seat back, adjusting the front and back slide of the seat cushion, and adjusting the height. In the operation section of the adjustment mechanism in which the adjustment levers of the mechanism are provided in one place, the rotating bodies integrally connected to the adjustment levers of the first adjustment mechanism and the second adjustment mechanism are rotatable with respect to each other. At the same time, the rotating body on the outer circumferential side is supported by a bearing member, and a bracket is integrally provided on the adjustment lever of the third adjustment mechanism, and the bracket is rotatably fitted on the rotating body on the outer circumferential side. This is an operating section of an adjustment mechanism in a characteristic front seat device.

[Example of idea]

Hereinafter, one embodiment of the present invention will be described based on the drawings. However, the overall front seat equipment 1
Since it is the same as that shown in FIG. 1 earlier, a new explanation will be omitted here. Operation section A of the first to third adjustment mechanisms for adjusting various functions
The same applies to providing the seat bag 4 on the side surface thereof. However, in this embodiment, the operating section A is configured as shown in FIG. In the figure, 20 is a first adjustment lever for operating the first adjustment mechanism, and a shaft 21, which is a rotating body, is connected along the axial direction of the first adjustment lever. A second adjustment lever 2 is located on the back side of the first adjustment lever 20.
2 is provided, and a pipe 23, which is a rotating body, is connected to this. The pipe 23 is rotatably fitted into the shaft 21, and its outer peripheral side is supported by a bearing member 24. Further, a third adjustment lever 25 is provided on the back side of the second adjustment lever 22, and as shown in FIG. A bracket 26 is integrally provided. This bracket 26 is rotatably fitted to the outer peripheral surface of the pipe 23 so as to hold the bearing member 24 from both sides thereof. Needless to say, the shaft 21, pipe 23, and bracket 26 are each connected to a not-shown operating portion of each adjustment mechanism.

Thus, by operating the first to third adjuster levers 20, 22, 25 as necessary, a desired function can be obtained.

Furthermore, when manufacturing the operating part A, the precision can be lowered by the reduction in the number of pipes, and assembly becomes easier. Furthermore, since the bearing member 24 and the bracket 26 fit into the pipe 23, the overall size is reduced and no dedicated space is required.

[Effect of idea]

As explained above, according to the present invention, it is possible to achieve effects such as lowering the precision of manufacturing and assembly, thereby reducing costs, and achieving miniaturization to reduce the dedicated space.
