(Function, effect)
In the sheet 10 of the present embodiment, when the LED 34 is caused to emit light, the light emitted from the tip of the LED 34 is incident on the end of the bead core 24A that is a linear light guide, and the bead from the outer periphery of the bead core 24A. Light is emitted to the outside of the core 24A. And the light radiate | emitted from the bead core 24A is radiated | emitted outside via the cylindrical part 24Ba of the bead outer skin member 24B. Since the sheet 10 of the present embodiment emits light from the ball edge 24 in various directions, it is excellent in light visibility and can enhance the decorative effect.
次に、車両の製造過程の一例を以下に説明する。
先ず、成形玉縁セット28の製造について説明する。
成形玉縁セット28は、予め成形しておいたソケット26を開き、同じく予め成形しておいた玉縁24を、その端部が光源嵌合凹部36に近接し、かつソケット嵌合部25が第1の部材26Aのシート接合部嵌合凹部38Bに嵌合するように玉縁24の端部側を第1の部材26Aの玉縁嵌合凹部38に配置し、その後、第1の部材26Aに第2の部材26Bを重ね合わせて突起40を穴42に圧入して玉縁24の端部をソケット26に固定することで完成される。なお、玉縁24の端部は、先に第2の部材26Bのシート接合部嵌合凹部38Bに嵌合させても良い。
Next, an example of a vehicle manufacturing process will be described below.
First, the production of the molded bead set 28 will be described.
The molded ball edge set 28 opens a socket 26 that has been molded in advance, and the ball edge 24 that is also molded in advance is close to the light source fitting recess 36 and the socket fitting portion 25 is The end side of the bead 24 is disposed in the bead fitting recess 38 of the first member 26A so as to be fitted into the sheet joint fitting recess 38B of the first member 26A, and then the first member 26A. The second member 26 </ b> B is overlaid and the protrusion 40 is press-fitted into the hole 42 to fix the end of the edge 24 to the socket 26. In addition, you may make the edge part of the edge 24 fit to the sheet | seat junction part fitting recessed part 38B of the 2nd member 26B previously.
そして、この成形玉縁セット28を用いて、シート10を製造(車体とは別に)する。なお、シート10は、玉縁24の端部側が予め決められた寸法分だけシート外方へ突出させておく。
一方、車体にはLED34及び配線44をシート取付部位に予め配置しておく。
And the sheet | seat 10 is manufactured (separately from a vehicle body) using this shaping | molding bead set 28. FIG. In addition, the sheet | seat 10 is made to protrude outward of a sheet | seat by the dimension by which the edge part side of the ball edge 24 was decided beforehand.
On the other hand, the LED 34 and the wiring 44 are previously arranged in the seat mounting portion on the vehicle body.
そして、通常通り、完成したシート10を車体のシート取付部位に取り付け、その後、ソケット26を開き、LED34をソケット26の例えば第1の部材26Aの光源嵌合凹部36に配置し、その後、第1の部材26Aに第2の部材26Bを重ね合わせて突起40を穴42に圧入する。これによって、LED34ソケット26に固定され、LED34の光軸と線状導光体である玉縁芯24Aの軸心とが一致する。なお、LED34を取り付けた後のソケット26は、シート10の目立たない場所に配置する。 Then, as usual, the completed seat 10 is attached to the seat attachment portion of the vehicle body, then the socket 26 is opened, and the LED 34 is disposed in the light source fitting recess 36 of the first member 26A of the socket 26, and then the first The second member 26B is superimposed on the member 26A, and the protrusion 40 is press-fitted into the hole 42. As a result, the LED 34 is fixed to the socket 26, and the optical axis of the LED 34 coincides with the axis of the ball core 24A that is a linear light guide. Note that the socket 26 after the LED 34 is attached is disposed in a place where the sheet 10 is not conspicuous.
このように、本実施形態では、シート10を車体に取り付けた後、工具や複数の部材を用いずに、LED34をソケット26に簡単に固定することができ、しかもLED34の光軸と玉縁芯24Aの軸心とを面倒な調整作業等をせずに一致させることができ、LED34の光を効率的に玉縁芯24Aの端部に入射させることができる。 As described above, in the present embodiment, after the seat 10 is attached to the vehicle body, the LED 34 can be easily fixed to the socket 26 without using a tool or a plurality of members. The axis of 24A can be matched without troublesome adjustment work and the light of the LED 34 can be efficiently incident on the end of the edge core 24A.
また、玉縁24は、ソケット26の玉縁嵌合凹部38に嵌合しているので、振動や玉縁24に張力が作用しても、玉縁24がソケット26に対してずれたり、玉縁24がソケット26から抜けることは無い。同様に、LED34も光源嵌合凹部36に嵌合しているので配線44に張力が作用してもLED34がソケット26から抜けることは無い。
これにより、玉縁芯(線状発光体)24Aの発光量が低下したり、玉縁芯24Aが発光しなくなる等の不具合を生じる虞が無い。
Further, since the bead 24 is fitted in the bead fitting recess 38 of the socket 26, even if vibration or tension is applied to the bead 24, the bead 24 may be displaced with respect to the socket 26. The edge 24 does not come out of the socket 26. Similarly, since the LED 34 is also fitted in the light source fitting recess 36, the LED 34 does not come out of the socket 26 even if tension is applied to the wiring 44.
Thereby, there is no possibility of causing problems such as a decrease in the amount of light emitted from the ball edge core (linear light emitter) 24A, or the ball edge core 24A not emitting light.
