Come to work.

<About the first and second operation levers 31, 32>
The first operation lever 31 is a lever that operates the front / rear slide device of the vehicle seat 10 and is formed wide because a relatively large pulling operation force is required. Further, the second operation lever 32 is a lever for operating the tip-up device of the vehicle seat 10, and is formed narrower than the first operation lever 31 because a smaller pulling operation force may be required. As shown in FIG. 4, the first operating lever 31 and the second operating lever 32 have the same configuration and are formed symmetrically. Moreover, the 1st operation lever 31 and the 2nd operation lever 32 are set to the same height dimension. As shown in FIG. 2, on the surfaces of the first operation lever 31 and the second operation lever 32, there are design portions 31e and 32e composed of an upper curved surface and a flat surface located below the curved surface. Is provided. And the lower back side of the design parts 31e and 32e of the 1st operation lever 31 and the 2nd operation lever 32 is the operation parts 311 and 321 which a finger | toe hangs at the time of operation, as shown in FIG. In the operation portions 311 and 321 of the first operation lever 31 and the second operation lever 32, laterally extending protrusions 311t and 321t are formed at equal intervals in the vertical direction.

  As shown in FIG. 4, side walls 313 and 314 are formed on both sides in the width direction of the first operation lever 31 in a state of being bent backward with respect to the design part 31 e, and left and right side walls 313 and 314. Are provided with bearing portions 313j and 314j through which the rotation center shaft 25 passes. Further, side wall portions 323 and 324 are formed on both sides in the width direction of the second operation lever 32 in a state of being bent rearward with respect to the design portion 32e, and rotation center axes are respectively provided on the left and right side wall portions 323 and 324. Bearing portions 323j and 324j through which 25 is passed are provided. The rotation center shaft 25 is passed through the bearing portions 313j and 314j of the first operation lever 31 and the bearing portions 323j and 324j of the second operation lever 32, and the rotation center shaft 25 is the left and right bearings of the base body portion 23. Supported by the portion 24 and the central bearing portion 26. As a result, the first operation lever 31 and the second operation lever 32 are coupled to the base body 23 in a state where the first operation lever 31 and the second operation lever 32 can rotate about the rotation center shaft 25. As described above, since the first operation lever 31 is formed wider than the second operation lever 32, the central bearing portion 26 of the base main body portion 23 has the first operation lever 31 of the first operation lever 31 as shown in FIG. 5. Arranged on the back side.

  Here, a spacer 28s of the support plate 28 is sandwiched between the right side wall 314 of the first operation lever 31 and the left side wall 323 of the second operation lever 32 as shown in FIG. Thus, the first operation lever 31 and the second operation lever 32 are held so as not to contact each other. Further, as shown in FIG. 6, the right side wall portion 314 of the first operation lever 31 and the left side wall portion 323 of the second operation lever 32 are thick at positions that are continuous with the respective design portions 31e and 32e. Portions 314n and 323n are provided. Thereby, the dimension Sx of the clearance S between the design part 31e of the first operation lever 31 and the design part 32e of the second operation lever 32 is sufficiently smaller than the thickness dimension T of the spacer 28s. That is, since the gap S between the design portion 31e of the first operation lever 31 and the design portion 32e of the second operation lever 32 is reduced, the spacer 28s is hardly visible from the outside, and the appearance is improved.

  As shown in FIG. 4, the left side wall portion 313 of the first operation lever 31 is provided with a connecting portion 316 to which a wire of the front and rear slide device is connected in the vicinity of the bearing portion 313 j. The right side wall portion 324 of the second operation lever 32 is provided with a connecting portion 326 to which a wire of a tip-up device is connected in the vicinity of the bearing portion 324j.

  Around the rotation center shaft 25, as shown in FIG. 5, a first coil spring 27a for urging the first operation lever 31 in the direction of retracting the base main body 23, that is, the downward rotation direction, and the second operation A second coil spring 27b that urges the lever 32 in a direction in which the lever 32 is stored in the base body 23 (downward rotation direction) is attached. Here, as shown in FIG. 2, the position where the first operation lever 31 and the second operation lever 32 are stored in the base body 23 is the original position of the first operation lever 31 and the second operation lever 32. is there. With the first operating lever 31 and the second operating lever 32 held in their original positions by the spring force of the first coil spring 27a and the second coil spring 27b, the lower ends of the first operating lever 31 and the second operating lever 32 A space F into which a finger can be inserted is formed between the vertical wall portion 23 w at the lower end of the base 22.

  As shown in FIG. 5, the first coil spring 27 a is held between the left side wall portion 313 and the spring receiving portion 315 of the first operation lever 31, and the second coil spring 27 b is the right side of the second operation lever 32. Is held between the side wall portion 324 and the spring receiving portion 325. Here, as described above, the first operating lever 31 requires a larger operating force than the second operating lever 32. Therefore, the spring force of the first coil spring 27a is set to be smaller than the spring force of the second coil spring 27b in order to make the operation force of the first operation lever 31 and the second operation lever 32 substantially equal.

<About the function of the lever device 20>
With the above configuration, the first operation lever 31 rotates upward against the spring force of the first coil spring 27a by placing a finger on the operation portion 311 of the first operation lever 31 and pulling the first operation lever 31 forward. To do. Accordingly, the wire or the like of the front / rear slide device is pulled by the first operation lever 31, and the front / rear slide device of the vehicle seat 10 is operated. At this time, since the spacer 28s exists between the first operation lever 31 and the second operation lever 32, the operation of the first operation lever 31 does not cause the second operation lever 32 to move. Further, by placing a finger on the operation portion 321 of the second operation lever 32 and pulling the second operation lever 32 forward, the second operation lever 32 rotates upward against the spring force of the second coil spring 27b. Thereby, the wire etc. of a tip-up apparatus are pulled by the 2nd operation lever 32, and the tip-up apparatus of the vehicle seat 10 comes to operate | move.

<Advantages of the lever device 20 of the vehicle seat 10 according to the present embodiment>
According to the lever device 20 of the vehicle seat 10 according to the present embodiment, the design portion 31e of the first operation lever 31 and the design portion 32e of the second operation lever 32 have a gap S as shown in FIGS. Are held in a line. That is, since a frame-like member or the like is provided so as to surround the first operation lever 31 and the second operation lever 32, the distance between the first operation lever 31 and the second operation lever 32 can be reduced accordingly. Thereby, the size of the base 22 can be reduced, and the lever device 20 can be made compact.

  Further, a spacer 28 s is provided between the first operation lever 31 and the second operation lever 32 in the vicinity of the rotation center shaft 25, and the design portion 31 e of the first operation lever 31 and the second operation lever 32 are provided. The gap dimension Sx between the design portions 32e is set to be smaller than the thickness dimension T of the spacer 28s. Thus, since the clearance gap between the design parts 31e and 32e in the adjacent operation levers 31 and 32 can be narrowed, the appearance of the lever apparatus 20 becomes good. The rotation center shaft 25 is supported by bearing portions 24 and 26 provided on the base 22 at both end portions and midway positions. For this reason, even when the width dimension of the base 22 is large, the rotation center shaft 25 can be stably supported.

<Example of change>
Here, the present invention is not limited to the above-described embodiment, and can be modified without departing from the gist of the present invention. For example, in the present embodiment, an example in which the spacer 28 s sandwiched between the first operation lever 31 and the second operation lever 32 is provided at the tip of the support plate portion 28 erected on the base main body portion 23 has been described. However, it is also possible to use a ring-shaped washer into which the rotation center shaft 25 is inserted instead of the spacer 28s, or to provide a bearing-like protrusion on the operation levers 31 and 32. Moreover, it is also possible to use the bearing part 26 which supports the middle position of the rotation center shaft 25 as the spacer 28s. Moreover, in this embodiment, the example which supports the 1st operation lever 31 and the 2nd operation lever 32 so that rotation around the rotation center axis | shaft 25 was shown was shown. However, a configuration in which the first operation lever 31 and the second operation lever 32 are slid relative to the base 22 is also possible. Furthermore, in the present embodiment, the lever device 20 including the first operation lever 31 and the second operation lever 32 is illustrated, but the present invention can also be applied to a lever device having three or more operation levers.
