Abstract

PURPOSE:To obtain the seat cushion which can additionally increase the resistance force to the drawing from the pulling parts of a skin material and is advantageous in terms of a cost and weight by joining support cloth member near to the slender holes on the rear surface of a pad member and mounting the front ends of the pulling parts to the supporting cloth member. CONSTITUTION:The pad member 21 is formed with a pair of the parallel slender holes 23 in the positions corresponding to link parts 22a provided on the skin material 22. Square worsted felt (support members) 24 are respectively joined to the rear surface 21a of the pad member 21 near the outer side. The worsted felt 24 are integrally impregnated and joined in the pad member 21 at the time of expansion molding of the pad member. Further, clip grooves 25 for mounting are respectively formed in parallel with the slender holes 23 adjacent to the outer side of the worsted felt 24. Notches 22b for drawing out the seat belt to the rear side of the cushion 20 are formed in the link parts 22a. The resistance force to the pulling force is improved in this way.

2. Description of the Related Art As conventional seat cushions, those shown in Japanese Utility Model Application Laid-open No. 144899/1989 and those shown in FIGS. 4 and 5 are known. Reference numeral 1 designates a seat cushion for an automobile seat, which is composed of a pad member 2 and a skin material 4. The pad member 2 is integrally made of urethane foam formed by foam molding, and has a thick front portion 2a and a thin rear portion 2b corresponding to a seat back (not shown). A pair of parallel elongated holes 3 are formed in the center of this pad member 2. and,
U-shaped insert wires 7 are inserted into the outer parts of the elongated holes 3 on the back surface 2c of the pad member 2, respectively. The cloth skin material 4 includes a seating portion 5 that covers the entire surface 2d of the pad member 2, and an enclosing portion 6 that is sewn to the front side of the seating portion 5 and covers the front portion 2a of the pad member 2.
It consists of The seating part 5 is provided with two joining parts 4a corresponding to the two elongated holes 3, and the joining parts 4a have a pull part 4b made of a piece of cloth.
are sewn on each. Next, how to cover the pad member 2 with this skin material 4. First, the tip of the pulling part 4b of the skin material 4 is guided from the front surface 2d through the elongated hole 3 to the back surface 2c, and the pulling part 4b is pulled. while attaching it to the insert wire 7 with a worm clip 8. Then, the skin material 4 is once coated on the entire surface of the pad member 2, and the end portion 6a of the surrounding portion 6 and the rear end portion 5a of the seating portion 5 are coated.
Fold it back to the back surface 2c of the pad member 2. Finally, the folded end portion 6a and rear end portion 5a are stopped at regular intervals with the worm clip 8 so as to bite the internal pad member 2, thereby completing the covering work.

[Problems to be Solved by the Invention] However, in such a conventional technique, the insert wire 7 is made into a U-shape to counteract the pulling force from the pulling portion 4b. Since the wire 7 itself is rod-shaped, the wire receives the pulling force, and there is a concern about reliability when a high pulling force is applied. Further, since the insert wire 7 is formed into a U-shape as described above, it becomes long, which is disadvantageous in terms of cost and weight.

[0004] The present invention has been made by focusing on such conventional technology, and provides a sheet that can further increase the resistance to pulling out of the skin material from the pulling part and is advantageous in terms of cost and weight. It provides a cushion.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the seat cushion according to the present invention has a support cloth member joined to the vicinity of the elongated hole on the back surface of the pad member, and a tip of the pull portion of the support cloth member. This is the one with the .

[0006]

[Operation] According to the seat cushion according to the present invention, the support cloth member is joined to the vicinity of the slotted hole on the back surface of the pad member,
Since the tip of the pull-out portion of the skin material is attached to this support cloth member, the support cloth member resists the pull-out force from the pull-out portion with its surface. Therefore, it is possible to improve the resistance against the pulling force, and furthermore, since the conventional U-shaped insert wire is not used, it is advantageous in terms of cost and weight.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Note that explanations that are redundant with those of the prior art will be omitted. A seat cushion 20 is made up of a pad member 21 and a skin material 22. A pair of parallel elongated holes 23 are formed in the pad member 21 at positions corresponding to the seam portions 22a provided in the skin material 22, and a square-shaped hole is formed on the back surface 21a of the pad member 21 near the outside thereof. coarse wool felt (support cloth member) 24 are joined to each other. This coarse felt 24 is used for the pad member 21
They are integrally impregnated and bonded during foam molding. Furthermore, clip grooves 25 for attachment are formed adjacent to the outside of these coarse felts 24 and parallel to the elongated holes 23.

[0008] Furthermore, a seatbelt (not shown) is attached to the seam portion 22a provided on the skin material 22.
A notch 22b is formed for pulling out to the surface side of 0. A pull part 26 is sewn onto the notch 22b, and includes a cylindrical part 26b having a mounting flange 26a formed on the base end side, and a tongue-shaped mounting piece 26c at the tip thereof.

The procedure for covering the pad member 21 with the skin material 22 is as follows. That is, the skin material 2
Pass the attachment piece 26c of the pulling part 26 of No. 2 through the elongated hole 23 of the pad member 21 and guide it to the back surface 21a, and while pulling the pulling part 26, attach the tip of the pulling part 26 to the outside of the coarse wool felt 24 corresponding to the clip groove 25. It is attached to the end using a worm clip 27. At this time, since the clip groove 25 is provided, attachment using the worm clip 27 is very easy. Then, as described above, the periphery of the skin material 22 is folded back to the back surface 21a of the pad member 21 and fixed with the worm clip 27.

[0010] As described above, since the pulling part 26 of the skin material 22 is attached to the coarse felt 24 provided on the back surface 21a of the pad member 21, the coarse felt 24 has a surface that resists the pulling force of the pulling part 26. This will improve resistance. Furthermore, since no insert wire is used as in the conventional case, the weight is reduced and the manufacturing cost is reduced. Furthermore, since a notch 22b for the seat belt is formed, it is convenient to attach the seat belt.

[0011] In the above embodiment, the seat cushion of an automobile was described, but the present invention is not limited to this, and the present invention can also be used as a seat cushion of furniture or the like. In addition, if the coarse felt 24 is joined only to the portion where it is secured by the worm clip 27, weight and cost can be further reduced.

0012

Effects of the Invention The seat cushion according to the present invention has the content as described above, in which a support cloth member is joined to the vicinity of the elongated hole on the back surface of the pad member, and a pull portion of the skin material is attached to the support cloth member. Since the tip of the support cloth member is attached, the surface of the support cloth member resists the pull-out force from the pull-out portion. Therefore, it is possible to improve the resistance against the pulling force, and since there is no need to use the conventional insert wire, it is advantageous in terms of cost and weight.
