[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for manufacturing a vehicle seat using an adhesive and a pattern-shaped adhesive forming jig for a vehicle seat, and more particularly, in a vehicle seat having a groove-shaped pattern shape on a seating surface portion or a back portion. The present invention relates to a vehicle seat manufacturing method and a vehicle seat pattern shape adhesive molding jig in which bonding between a pad and a cushion pad is good.
[0002]
[Prior art]
Conventionally, in a vehicle seat using an adhesive, a skin material and a cushion pad are arranged between the upper and lower molds, and the adhesive is interposed between the skin material and the cushion pad and integrally joined. As the adhesive, an adhesive film-like hot melt type adhesive or a solvent type adhesive has been used.
[0003]
Conventionally, as shown in FIG. 8, a pattern bar 130 serving as a pressing jig is disposed at a portion corresponding to the groove-shaped pattern shape 140 formed on the skin material 110 and the cushion pad 120. After the pattern-shaped portion is inserted and held in the pattern-shaped groove of the cushion pad 120, the skin material 110 is pressed against the cushion pad 120 with a crimping die (not shown), and the skin material 110 is bonded and fixed to the cushion pad 120.
[0004]
At this time, when using a hot-melt adhesive as the adhesive, use a crimping type equipped with a heating means such as a heater or steam, activate the adhesive by heating, The cushion pad was bonded.
[0005]
[Problems to be solved by the invention]
FIG. 8 shows a configuration in which the pattern bar 130 is arranged in the pattern shape 140 when the cross-sectional shape of the pattern shape 140 is substantially V-shaped. As shown in the drawing, when the cross-sectional shape of the pattern shape 140 is substantially V-shaped, there is a gap between the pattern bar 130 and the skin material 110, so that heat from the crimping die or cooling Cooling air is efficiently transmitted to the skin material 110 and the cushion pad 120, and heating and cooling can be performed in a short time.
[0006]
However, as shown in FIG. 9, when the cross-sectional shape of the groove-shaped pattern shape 140 is substantially U-shaped, by forming the pattern bar 130 in accordance with the pattern shape 140, the pattern bar 130 becomes thicker. As a result, the air permeability is interrupted.
[0007]
For this reason, heat and cooling air from the crimping mold are not easily transmitted to the skin material 110 and the cushion pad 120, and in the peripheral portion 150 including the pattern shape 140, hot melt is difficult to melt during heating, and heat does not escape during cooling. Therefore, there is a problem that the hot melt is difficult to solidify.
[0008]
Further, since the pattern bar 130 is a solid product made of a hard member, the thermal efficiency of the pattern bar 130 itself is poor, and the pattern bar 130 itself is difficult to heat and cool, so that hot melt heating and cooling are efficient. Could not be done.
[0009]
In addition, conventionally, the pattern bar 130 has a shape adapted to the groove-shaped pattern shape 140. Therefore, the pattern bar 130 is created by a method by casting or by controlling the processing size and shape by a program. It was performed by so-called NC processing. For this reason, the capital investment for processing the pattern bar 130 is required, and the processing is troublesome, resulting in high processing costs.
[0010]
Furthermore, in the portion where the groove-shaped pattern shape 140 is formed, the pattern bar 130 is pressure-bonded to the skin material 110 with a stronger pressing force than the other portions, and heating, cooling, and pressurization are performed. In the raising type skin material 110 such as the above, there is a problem in that hair fall and whitening of the skin material 110 occur in a portion in contact with the pattern bar 130.
[0011]
The objective of this invention is providing the manufacturing method of the vehicle seat using the adhesive agent which can shorten the shaping | molding cycle in an adhesion | attachment process, and the pattern shape adhesion forming jig of a vehicle seat.
[0012]
Another object of the present invention is to provide a method for manufacturing a vehicle seat capable of improving appearance merchantability, which is unlikely to cause hair falling in a groove-shaped pattern portion even with a raised type skin material. The object is to provide a pattern-shaped adhesive forming jig for a vehicle seat.
[0013]
Still another object of the present invention is to provide a vehicle seat pattern shape adhesive molding in which a cushion pad having a groove-shaped pattern shape and a skin material covering the cushion pad are bonded to each other using an adhesive. An object of the present invention is to provide a vehicular seat pattern shape adhesive forming jig that can be easily manufactured without requiring a large-scale processing facility.

The vehicle seat is formed by mounting a cushion pad 20 on a seat frame (not shown) and covering the cushion pad 20 with a skin material 10. A pattern shape is formed on the vehicle seat, and a groove 21 corresponding to the groove-shaped pattern shape is formed on the upper surface side of the cushion pad 20.
[0029]
The skin material 10 is formed in a predetermined shape in advance by molding, sewing, or the like. When the skin material 10 has a concave shape or stitched portion corresponding to the groove-shaped pattern shape, the pattern shape portion 11 of the skin material 10 is disposed so as to coincide with the groove 21 of the cushion pad 20. . The skin material 10 and the cushion pad 20 are bonded by an adhesive.
[0030]
The manufacturing method of the vehicle seat using the adhesive of this example includes an adhesive application process, a skin covering process, a heating process of the skin material 10 and the cushion pad 20, and a skin material as a molding process. 10 and the cooling process of the cushion pad 20 are provided as main processes.
