Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting structure for an operating switch in a power seat.

[Conventional technology]

In vehicle seats, for example, the lifting operation of the seat cushion and the reclining operation of the seat back are performed electrically.
So-called power seats are widely practiced.

In this type of power seat, a predetermined adjustment operation is performed by operating an operation switch disposed on the side of the seat to differentially operate an electric motor built in the seat.

In this power seat, for example, as shown in FIG.
and fixing brackets 5a and 5b protruding from the sides of the seat cushion frame 1a and the reclining device section 2.
It is fixed by a screw 6.

Conventionally, the mounting structure of the operating switch 4 in this type of power seat is as shown in FIG. An operator 4a of the switch 4 is projected outward from the transparent light 9, and by swinging the operator 4a in the vertical direction, the electric motor is differentially operated to perform a predetermined adjustment operation of the seat. ing.

[Problem that the invention attempts to solve]

However, in this power seat,
The operating switch 4 is supported only by the case-shaped finisher 3, and the screw 6 fixing the finisher 3 to the cushion frame 1a has a mounting post 7 for mounting the operating switch 4. Since it is set in a position far away from the mounting part of the operation switch 4,
When the operator 4a is operated up and down, the finisher 3 is bent and wobbling, which is an inconvenience.

In order to eliminate this wobbling, for example, a boss part and a rivet part are provided inside the finisher 3 protruding near the mounting part of the operating switch 4, and this rivet part is provided on the seat cushion frame 1a side. There is a method of engaging and fixing it to a fixing member, but this finisher 3 requires forming the through hole 9 and the mounting post 7 in an inclined direction in order to mount the operation switch 4 in an inclined state. Slide core 10 as shown in FIG.
Due to the use of the mold 10 having a shape of 1, it was difficult to form the boss portion, the rivet portion 11, etc. inside the finisher 3.

Another possible method is to attach the operating switch 4 to the seat cushion frame 1a and then fix the finisher 3 to the seat cushion frame 1a, but in this case, the center positions of the operating switch 4 and the through hole 9 of the finisher 3 are There was a risk that the operation element 4a of the operation switch 4 could not be projected to the outside of the finisher 3 due to misalignment.

The present invention has been devised in view of the above, and provides a structure for mounting an operating switch in a power seat, which has a simple structure and allows the operating switch to be reliably mounted.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention has a case-shaped finisher fixed to the side of the seat cushion frame, a through hole formed in the side surface of the finisher, and a finisher located near the through hole. In a power seat, a mounting post is provided protruding from the back side, and an operating switch is attached to this mounting post with a screw so that the operating element protrudes outward from a through hole. A support plate is disposed between the seat cushion frame, one end of the support plate is fastened together with an operation switch to a mounting column using a screw, and the other end is connected to an engagement column provided on the seat cushion frame. It is made by engaging with the part.

[Effect]

By doing so, the operating switch is supported on the seat cushion frame side via the support member, so that the finisher does not wobble when the operating switch is operated.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 4. Parts corresponding to those of the conventional example shown in FIGS. do.

1 and 2 show a first embodiment of the present invention, in which an operating switch 4 is supported on the seat cushion frame 1a side via a support member. This support member is made up of a pair of engaging bodies and engaged bodies, and the supporting plate body 20 as the engaging body has an upper end of a central plate portion 20a protruding upward;
A mounting hole 21 is bored in this protrusion, and a front plate part 20b is formed from the front edge of the central plate part 20a.
is bent at a substantially right angle and extended, and the center plate portion 20
From the rear edge of a, the rear plate part 20c is the front plate part 20.
It is bent and extended at a substantially right angle in the direction opposite to b. Further, the lower end of the rear side plate portion 20c extends downward to form an engaging portion 20d, and both side edges of the engaging portion 20d are tapered.

Further, the support bracket 22 as an engaged body is formed in an L shape, and the support plate body 20 is attached to the horizontal surface portion of the support bracket 22.
An engagement hole 22a into which the engagement portion 20d of the support plate 20 is inserted in a meshing manner is formed, and the engagement hole 22a has a quadrilateral shape that is wider than the thickness of the engagement portion 20d of the support plate 20, that is, long in the front-rear direction. is formed.

When the operating switch 4 is attached to the finisher 3 by the screw 8, the support plate body 20 is connected to the operating switch 4 by tightening the mounting hole 21 of the central plate portion 20a to the mounting post 7. In this state, the edge of the front plate portion 20b of the support plate 20 comes into contact with the inner surface of the finisher 3.

On the other hand, the support bracket 22 is fixed at a predetermined position on the side of the seat cushion frame 1a, that is, at a portion corresponding to the support plate 20 to which the finisher 3 is attached, by welding or the like on a vertical surface.

The finisher 3 to which the operation switch 4 and support plate body 20 are attached in this manner is aligned with the side of the seat cushion 1, and the engagement portion 20d of the support plate body 20 is inserted into the engagement hole 22a of the support bracket 22.
After that, the finisher 3 is fixed to the seat cushion frame 1a with the screw 6 in the same manner as in the conventional example described above.

In this state, the engagement portion 20d of the support plate 20 is engaged with the engagement hole 22a of the support bracket 22 at its inner and outer edges, thereby allowing the operating switch 4 to engage the support plate 20 and the engagement hole 22a. It is supported on the seat cushion frame 1a side via the support bracket 22, and the force applied to the operating switch 4 is therefore received on the seat cushion frame 1a side, so the operating switch 4 is supported on the seat cushion frame 1a side. The finisher 3 is securely fixed and held in the same way as when it is directly fixed to the holder, and therefore the finisher 3 does not bend or wobble when the operating switch 4 is operated.

Moreover, in this example, the edge of the front plate portion 20b of the support plate body 20 is brought into contact with the inner surface of the finisher 3, so that the finisher 3 can reliably receive the force applied from the outside. Furthermore, since the engaging portion 20d of the support plate 20 is formed in a tapered shape, the support plate 20 can be easily inserted into the engagement hole 22 of the support bracket 22 during assembly.
a, and in the assembled state, the engaging portion 20d of the support plate 20 is engaged with the engagement hole 22a of the support bracket 22 in a wedge-shaped manner, so that the support plate 20 is more firmly fixed and held, and therefore the finisher 3 can more reliably prevent wobbling.

Further, since the engagement hole 22a of the support bracket 22 is formed wider than the thickness of the engagement portion 20d of the support plate body 20, some misalignment may occur between the support plate body 20 and the support bracket 22. Even though
During assembly, the engaging portion 20d of the support plate 20 is inserted and fixed without any problem.

Furthermore, FIGS. 3 and 4 show a second embodiment of the present invention, and in this second embodiment, the shape of the support member is formed to be different from that of the support member of the first embodiment. There is. That is, the support plate body 30 as an engaging body has an upper plate part 3 with respect to the center plate part 30a.
0b is bent at a substantially right angle, and the lower plate part 30c is bent in the opposite direction to the upper plate part 30b, and the mounting hole 3 is formed in the upper plate part 30b.
1, it is fixed to the finisher 3 together with the operating switch 4 by a screw 8. Further, the support bracket 32 as an engaged member is formed in a round shape and is fixed to the seat cushion frame 1a by welding or the like at both side flat portions 32a and 32b, and the central convex portion 32c of the support bracket 32 is fixed to the seat cushion frame 1a by welding or the like.
The gap between the seat cushion frame 1a and the support plate 30 is larger than the thickness of the support plate 30, and the inner width of the central convex portion 32c is larger than the width of the support plate 30. The lower plate portion 30c of the support member 30 is inserted into the gap between the central convex portion 32c of the support member 32 and the seat cushion frame 1a.

When the support plate 30 is inserted into the support bracket 32 in this manner and the finisher 3 is fixed with the screw 6 so as to be pressed against the side of the seat cushion 1, the lower plate portion 30c of the support plate 30 is The support member 30 is bent and deformed, and its elasticity allows the support member 30 to press against the central protrusion 32 of the bracket 32.
The support plate 30 is pressed against the seat cushion frame 1a by this pressure contact force at two points: the inner upper end of the seat cushion frame 1a and the lower side end of the seat cushion frame 1a.
It is supported in a fixed state relative to a.

In this second embodiment as well, the operating switch 4 is supported on the seat cushion frame 1a side via a support plate 30 and a support bracket 32 as support members in the same manner as in the first embodiment described above. Therefore, the finisher 3 will not wobble when the operating switch 4 is operated.

Furthermore, in the above first and second embodiments,
Since the operation switch 4 is fixedly supported on the seat cushion frame 1a side through the support plates 20, 30 and support brackets 22, 32 as support members inside the finisher 3, the appearance does not change at all. Moreover, during assembly, when fixing the finisher 3 to the seat cushion frame 1a, the support plate 20,
30 can be easily fixed and supported by simply inserting it into the support brackets 22, 32, which has advantages such as good workability.

Note that the shapes of the support plates 20, 30 and the support brackets 22, 32 constituting the support member are not limited to those shown in the first and second embodiments described above, and can be formed into various shapes. It is.
