Description

[Detailed Description of the Invention] The present invention relates to a seat, particularly a reclining seat for a vehicle or the like.

Generally, a reclining seat consists of a seat 1 and a tiltable backrest 2, as shown in FIG.
It consists of a frame made of spring material, a filling made of a cushioning material such as polyurethane, and a front member 3 made of leather or the like covering the filling.

In manufacturing the back support part 2, the front member 3, which has been sewn into a bag shape in advance, is placed on the filling, and then the open part of the front member 3 at the lower end 2 of the back support part 2 is closed. That's what I do.

FIG. 2 is a sectional view showing the opening of this front member 3,
In the figure, the front member 3 consists of a front front member 31 and a rear front member 3□, the lower end of the front front member 3 is folded back, and this folded portion 4 is sewn to the front front member 3. The end wire 5 is inserted into the hollow portion thus obtained.

Further, the lower end of the rear front member 3□ is also folded back and sewn to form a border.

A connecting piece 6 is branched on the inside of the lower part of this rear surface member 3□, and the lower end of this connecting piece 6 is folded back and sewn.
An end wire 7 is placed in the hollow portion formed by this folding.
is inserted.

The inserted portions of the end wires 5, 7 are clamped with clips 8 shown in FIG. 3 and are thereby connected to the pieces.

The lower part of the rear surface member 3□ serves as a covering part 9 to improve aesthetic appearance by covering this connection part.

However, according to the above structure, the lower ends of the connecting piece 6 and the front face member 3 must be folded back and sewn together, which makes the folding work complicated and cannot improve mass productivity.

In addition, since a gap occurs in the portion of both end wires 5 and γ that is not fixed by the clip 8, a covering part 9 is required to hide this, but providing such a covering part 9 is difficult in terms of mass production. undesirable.

The present invention eliminates the above drawbacks by making it possible to close the opening with a simple operation and covering the entire length of the opening, and will be described in detail below using examples.

FIG. 4 shows the seat according to the present invention, particularly the front upholstery 3 constituting the backrest. 10 is a cross-sectional view showing the connecting portion between the rear surface material 3 □ and the rear surface material 3 □ . In the same figure, 10 is a long fixing part made up of stators 10 □ and 10 □ , and is held by a long holding frame 11 . integrated.

Stator 10. ．． 2 is the front surface material 3 and the rear surface material 3□
horizontal pieces 12 to which are sewn, vertical pieces 13 that hang down from the butting ends of each horizontal piece 12, and protruding pieces that protrude in opposite directions from the lower ends of the vertical pieces 13 and have semicircular lower surfaces. It consists of 14.

The holding frame 11 has a substantially bowl-shaped cross section, and its inner surface is in close contact with the lower surface of the protruding piece 14.

A blocking piece 15 extends from the inner surface of the end portion of the holding frame 11 and comes into contact with the upper surface of the protruding piece 14 .

That is, the protruding piece 14 is held and integrated with the holding frame 11.

The end of the holding frame 11 extends toward the front member 31.3□ side and covers the seam l.

Note that the fixing portion 10 and the holding frame 11 are made of synthetic resin.

According to the above configuration, after the ends of the front members 30 and 32 are sewn to the horizontal piece 12 of the stator 101. By fitting, the front members 31 and 32 can be connected.

In this case, since the holding frame 11 surrounds the entire length of the protruding pieces 14, there is no gap as in the conventional case, and since the seam 1 is hidden, only one holding frame 11 is present in appearance. , the aesthetic appearance is excellent.

Therefore, the conventional covering section 9 can be omitted.

Also, the front member 3□. 32 can be simply sewn onto the horizontal piece 12, and since there is no need to fold it back, the sewing process can be carried out quickly.

5 and 6 show the seat according to the present invention, particularly the front member 31,
4 is a diagram showing the vicinity of the connecting portion of 3□, and the same parts as in FIG. 4 are denoted by the same reference numerals.

In FIG. 5, a cylindrical body 16 is provided at the lower end of the vertical piece 13, and this cylindrical body 16 is fitted into a circular groove 17, 17 provided on the inner surface of the flat holding frame 11, respectively.

Note that the end portion of the holding frame 11 extends horizontally to cover the seam.

Thereby, the picture surface covering material 31.3□ can be connected.

In FIG. 6, each of the projecting pieces 14 is plate-shaped and inserted into a rectangular hole in the holding frame 11.

As explained above, according to the present invention, the end of the front facing material, the horizontal piece connected to the end of the rear facing material, and the vertical piece hanging down from the butt end of this horizontal piece. Since it is composed of at least an elongated stator and an elongated holding frame that surrounds the lower part of the vertical piece of each stator, it is possible to easily connect the front members, and it also has the effect of providing an excellent aesthetic appearance.
