Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a structure of a terminal fixing portion of a skin material in a vehicle seat such as an automobile seat (seat).

[0002]

[Prior Art]

 In a conventional automobile seat, a frame or insert wire is embedded along the periphery of a foam cushion body, and a large number of recesses are formed to expose a portion of the back surface of the cushion body to expose the frame and the like. There is one in which a recess is provided and a frame or the like in the recess is bound with an end of a skin material for covering the front surface of the cushion body with a hog ring.

This will be described with reference to FIGS. 4 to 9. FIG. 4 shows a rear seat back (RB), and FIG. 4 shows a foam cushion body before covering the skin materials (21) and (22). 1) shows the back surface, and the frame (32) and the insert wire (31) are embedded in the cushion body (1) at a position close to the back surface side, and the frame (32) and the insert wire (31) are The recesses (4) are provided at intervals so that the ends (23) of the skin material (22) can be bound, and the frame (32) and the insert wire (31) are provided in each recess (4). A part of) is exposed as shown in FIGS.

7 to 9 show that the front surface of the cushion body (1) is covered with the skin materials (21) and (22), and the end (23) of the skin material (22) is covered with the hog ring (5). The state where it is bound to the frame (32) and the insert wire (31) in the recess (4) is shown. The skin materials (21) and (22) are sewn in a bag shape in advance, the ends (23) of the openings are folded back to form a bag shape, and the core wire (24) is inserted therein. In the figure, (2A) shows a joint portion of the skin materials (21) and (22).

[0005]

[Problems to be solved by the device]

 Since the ends (23) of the above skin material (22) are bound by the hog ring (5) in the recess (4) provided on the back surface of the cushion body (1) at intervals, The skin material (22) at the binding point is pulled, and by pulling this skin material (22), the cushion body between the recess (4) and the peripheral edge of the cushion body (1) is as shown in FIG. Crushed.

Therefore, the portion of the cushion body (1) where the skin material (22) is bonded is recessed on the back surface side, and the tension between the binding site and the non-bonded portion of the skin material (22) is increased. However, as shown in FIG. 7, the joining point (2A) meanders. As a result, the quality of the appearance of the seat is very poor, and it is not possible to assemble a seat of consistent quality. Therefore, an object of the present invention is to prevent the appearance quality of the seat from being deteriorated by the binding of the end of the skin material by the hog ring.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a notch portion formed on the back surface of the cushion body in the conventional product by cutting out a part of the back surface of the cushion body in the frame or insert wire direction from the periphery thereof. It is characterized by being provided.

[0008]

[Action]

 The cutouts on the back of the cushion body do not crush the cushioning material near the binding point by pulling the skin material, even if the skin material is bound by hogging at intervals. . In addition, the entire end of the skin material is pulled evenly and bound.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a cross-sectional view of the cushion body (1) in a state before being covered with the skin materials (21) and (22) and showing a portion corresponding to line VV in FIG. This cushion body (1) has an insert wire (31) and a frame integrally foamed therein and embedded in the same manner as the above-mentioned conventional product, and has a large number of recesses for connecting the ends (23) of the skin material (22) to the back side thereof. The recesses (40) are provided at intervals so that the insert wire (31) and a part of the frame are exposed in the recessed recesses (40).

A notch (10) is provided around the back surface of the cushion body (1). The cutout portion (10) is cut out in a gradually lower slope from the peripheral edge (101) on the back surface of the cushion body (1) to a position near the insert wire. Then, the lowermost end (102) of the cutout portion (10) is made substantially at the same height as the insert wire (31). Therefore, the peripheral edge side of the cushion body (1) of the concave portion (40) is open, and the insert wire (31) is embedded between the large number of concave portions (40).

FIG. 2 shows locations where the ends (23) of the skin material (22) are bound by the hog ring (5), and FIG. 3 shows the locations between the binding points. The skin materials (21) and (22) are sewn into a bag shape like the conventional product, and the core wire (24) is inserted through the terminal (23), and the stitching point (2A) is a cushion body. The cushion body (1) is covered so as to be located on the peripheral edge (101) of (1). Then, the end (23) of the skin material (22) is attached to the insert wire (31) or the frame in the large number of recesses (40) provided on the back surface of the cushion body (1) as in the conventional case. ) And fix the skin materials (21) and (22).

Thus, since the notch (10) is provided around the back surface of the cushion body (1), when the end (23) of the skin material (22) is bound by the hog ring (5). The cushion body (1) is not crushed by the tension of the skin material (22). Further, the ends (23) of the skin material (22) are all arranged in the cutout portion (10) and do not meander.

[0013]

[Effect of the device]

 According to the present invention, the entire end of the skin material is disposed in the notch portion provided around the back surface of the cushion body, and is bonded to the insert wire or the like by the hog ring with a gap. Therefore, unlike the conventional product, only the part where the end of the skin material is bound by the hog ring is not strongly pulled. In addition, the cushion body is not crushed by the tension of the skin material. Therefore, since a partial recess is not formed around the back surface of the sheet and the joint portion of the skin material does not meander, the appearance quality of the sheet is improved.
