Description

[Detailed description of the invention] (Industrial application field) This invention relates to a vehicle seat (automobile seat).
More specifically, the present invention relates to an improvement in the structure of an insert wire embedded within a cushion member of a seat cushion.

(Prior Art) Conventionally, as this type of vehicle seat, one shown in FIG. 4 is known. In the figure, 1 is a seat cushion for an automobile seat, which is formed by placing a cushion member 4 on a spring support member 3 stretched over a frame-like frame 2, and covering this cushion member 4 with a skin member 5a. be done. A suspension wire 5, a trim wire 6, etc. are buried within the cushion member 4. The hanging wire part 5 is embedded in the cushion member 4 in order to suspend the button 7 attached to the surface of the skin member 5a, and the trim wire 6 is embedded in the cushion member 4 in order to lock the end of the skin member 5a to the frame 2. 4.

(Problems to be Solved by the Invention) According to the automobile seat having the above configuration, the skin member 5 is provided in the cushion member 4 of the seat cushion 1.
It is necessary to bury the trim wire 6 for locking the button 7 and the hanging wire 5 for hanging the button 7. When burying the trim wire 6 and the hanging wire 5, prepare the respective wires and bury them at each location. As a result, the work required time and effort, and since wires having the functions of trimming and hanging wires were prepared, the number of parts increased and costs increased.

This idea was made to solve these problems, and it is possible to reduce the number of wire parts buried in the cushion member, thereby reducing costs, and to provide a vehicle seat with good workability. The aim is to obtain insert wires of

(Means for Solving the Problems) The insert wire for a vehicle seat according to the present invention has an insert wire having an uneven shape embedded in a cushion member of a seat cushion that has a groove for suspending the skin on the seating surface. The insert wire includes a convex suspension wire portion that suspends the upper surface of the skin member covering the cushion member into the suspension groove, and a suspension wire portion that is continuous with the suspension wire portion and that is attached to the skin member. a trim wire portion having a concave shape that locks the end stopper, and the hanging wire portion is disposed in the hanging groove of the cushion member; The top surface of the skin member is exposed and suspended from the hanging wire portion of the insert wire, and the end of the skin member is locked to the trim wire portion of the insert wire, and the top surface of the skin member is suspended from the trim wire portion of the insert wire. The insert wire can be used both as a hanging wire and as a trim wire for locking the end of the skin member.

(Example) An example of this invention is shown in Figures 1 to 3.
This will be explained based on the diagram. In the figure, 11 is a car seat, with a seat back 12 and a seat cushion 1.
It consists of 3. The seat cushion 13 is constructed by placing a foam part 14, which is a molded cushion member, on a spring support member 16 stretched over a frame 15, and then attaching the foam part 14 to a skin member 17. Formed by coating. The foam part 14 has insert wires 18 and 19 having an uneven shape on its front and left and right parts.
will be buried. A front wire 18 having protrusions 18a and recesses 18b formed at predetermined intervals along the left and right direction of the foam pad 14 is embedded in the front part of the foam pad 14. Similar to the wire 19, convex portions 19 are provided at predetermined intervals.
a and the left and right wires 19 with recesses 19b formed therein.
will be buried. The wires 18 and 19 have convex portions 18a,
19a is a hanging wire part, and recesses 18b, 1
9b is a trim wire part, the convex parts 18a and 19a are arranged in the suspension grooves of the foam part 14, the upper surface of the skin member 17 is suspended in the convex parts 18a and 19a, and the concave parts 18b and 19b are made of foam part 14. It is exposed to the outside from the bottom surface of the pad 14, and the end 17a of the skin member 17 is locked in the recesses 18b and 19b. The end portions 19c of the left and right wires 19 protrude from the rear portion of the foam pad 14 to form folded portions 19d. The ends 17a of the skin member 17 are hooked into the recesses 18b and 19b of the front and left and right wires 18 and 19 of the foam pad 14, respectively.
The outer skin member 1 is secured to the convex portions 18a and 19a.
7 is suspended and covered with this skin member 17. Furthermore, the terminal portions 19 of the left and right wires 19
c is used for attachment to the body.

The insert wire of the vehicle seat according to the above structure has protrusions 18a and 19a arranged at predetermined intervals in the foam part 14 forming the seat cushion 13.
The front wire 18 and the left and right wires 19 are buried in which the recesses 18b and 19b are sequentially formed, and the protrusions 18a and 19a of the front and left and right wires 18 and 19 are buried.
While suspending the skin member 17 in the recess 18
The ends 17a of the skin member 17 can be locked to the ends 17a of the skin member 17, and the protrusions and recesses of the front and left and right wires 18, 19 can be used for suspending and locking the skin member 17. Since it can have multiple functions, it is possible to reduce the number of parts and work hours, and reduce costs. Furthermore, the terminal portions 19c of the left and right wires 19 can be used for attachment to the body, and furthermore, the functionality thereof can be improved and the work effort can be reduced.

In the above embodiment, the protrusions 18 are sequentially formed on the front and left and right wires 18 and 19 at predetermined intervals.
A, 19a and recesses 18b, 19b are formed, but the present invention is not limited to this.
For example, protrusions may be formed alternately in the vertical direction on the foam parts.

(Effect of idea) According to the present invention, the following effects are achieved.

An insert wire with an uneven shape is embedded in the cushion member of the seat cushion, and a convex suspension wire part and a concave trim wire part are formed continuously on this wire part, and the suspension wire part is concave. The insertion wire portion is disposed in the hanging groove of the cushion member to hang the upper surface of the skin member, and the trim wire portion is exposed to the outside from the bottom surface of the cushion member to lock the end of the skin member. The insert wire can be used both for suspending the skin member and for locking the end.

Therefore, it is not necessary to separately embed the wire for suspending the skin member and the trim wire for locking the end of the skin member in the cushion member, and the number of parts can be reduced.

Loads are generated in opposite directions on the suspension wire portion and the trim wire portion of the insert wire, and the safety of the insert wire within the cushion member is improved compared to a case where a load is generated in one direction.

Therefore, the insert wire does not fall out from inside the cushion member to the outside, and the durability of the insert wire is improved.
