Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the wiring structure of a cushion sheet.

(Prior Art) For example, when attaching an electrical product such as a speaker to a headrest, conventionally the cord was inserted deep inside the sponge-like cushion material in the headrest, or the cord was run along the surface of the cushion material.

(Problem that the invention aims to solve) However, in the former case, the cord is routed deep inside the cushion material, which complicates manufacturing and makes it difficult to repair or replace the cord in the event of a failure. It was hot.

In addition, in the latter case where the cord was exposed and stretched over the surface of the cushion material, the skin member that further covered the surface of the cushion material swelled, resulting in an improper appearance.

(Means for Solving the Problem) Therefore, the present invention has been devised so that it looks good in appearance and also allows the cord to be attached and replaced easily. Wiring groove 1 with approximately the same shape as
1, a cord 12 is fitted into the groove, and the outer surface of the cord 12 is covered with a skin member 6.

One embodiment of the present invention will be explained with reference to the drawings. 1 is a headrest, and the headrest 1 is a seat 2
Attach it to the top of the seat bag 3. Reference numeral 4 denotes a speaker, which is attached inside the side surface 5 of the headrest 1. 6 is the skin of the headrest 1, 7 is the cushion material of the headrest 1, 8 is the frame of the headrest 1, the base of the stay 9 is attached to the frame 8, and the tip of the stay 9 is attached to the leg 1 of the headrest 1.
0, and is fitted into the mounting tool on the upper part of the seat 2 so as to be freely inserted and removed.

Therefore, the wiring groove 1 is formed on the surface of the cushion material 7.
form 1. A cord 12 is fitted into the wiring groove 11, and the outer skin 6 is covered from above. Wiring groove 1
Reference numeral 1 has a shape that is approximately the same as the cross-sectional shape of the cord 12, and the wiring groove 11 is formed into a square shape by the skin 6 covering the surface thereof. The wiring groove 11 is
In the embodiment, it is formed on the outer surface of the cushion material 7 of the headrest 1, but it can be applied to either a backrest or a seat.

14 is a connector attached to the end of the cord 12, and is connected to the main body of the stereo or the like. 15 is the seat cushion of the seat 2.

(effect) Next, we will discuss the effect.

When attaching the speaker 4 to the side surface 5 of the headrest 1, the cushion material 7 of the headrest 1 is provided with a wiring groove 11 having approximately the same cross-sectional shape as the cord 12 from the side surface 5 to the rear surface 13 and below the legs 10. Since the cord 12 leading to the speaker 4 can be easily wired by fitting it into the wiring groove 11, the cord 12 can be wired without exposing the cord 12 by covering its upper surface with the skin 6. The inserted cord 12 is in the wiring groove 11
Since the cross-sectional area of the cord 12 is approximately the same as or slightly deeper than the cross-sectional area of the cord 12, the cord 12 prevents unevenness from forming on the surface of the skin 6 and prevents wrinkles. The cord 12 is fitted into the wiring groove 11 and wired from the headrest 1 to the seat back 3 of the seat 2, and the cord 12 is attached integrally with the headrest 1, so it is not visually obtrusive and can be directly connected when people get on and off the seat. The cord 12 can also be protected without being hooked.

However, if the cord 12 becomes disconnected or deteriorates, remove the skin 6 of the headrest 1 and remove the cord 12.
When the end of 2 is pulled, the cord 12 is inserted into the wiring groove 11.
It can be easily removed from the inside and can be easily repaired or replaced.

(Effects) As mentioned above, in the past, the cord was inserted deep inside the sponge-like cushion material of the headrest, making manufacturing complicated and making it difficult to repair or replace the cord in the event of a failure.
In addition, when the cord was exposed and stretched on the surface of the cushion material, the skin material swelled, resulting in an undesirable appearance.

However, in the present invention, as described above, a wiring groove 11 having a shape substantially the same as the cross-sectional shape of the cord 12 is formed on the surface of the cushion material 7, and the cord 12 is inserted into the groove.
Since the wiring structure of the cushion sheet is configured such that the outer surface is covered with the skin member 6, a. Since the cord 12 is wired, the cord 12 can be protected.

(b) Therefore, it is possible to eliminate causes of malfunctions such as cords being caught when people get on and off the train.

C. Since the cord 12 is wired in the wiring groove 11 formed between the skin 6 of the head rest 1 and the cushion material 7, the surface of the skin 6 has no irregularities, resulting in a good appearance and high commercial value.

Repair and replacement of the code 12 can be done easily and easily.

E) The manufacturing process can be simplified, making it cheaper.

This effect is achieved.
