[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a suspension-type planar fastener-integrated foaming type, and particularly, in a seat in which a skin is suspended, is used when a planar fastener constituting a suspended portion of the seat is integrally foamed with a cushion material. Regarding molds.
[0002]
[Prior art]
Conventionally, the seat trim of the seat has been suspended for the purpose of preventing the seat skin from lifting and designing. As shown in FIG. 7, the suspension is performed by inserting the wire 152 into the cushion pad 151 and locking the steel wire 153 and the insert wire 152 with an ohmic clip (not shown) from the seat surface side. The technique of hanging is known. Symbol H is a skin, symbol 154 is a hanging bag, and symbol 155 is a stitched portion.
[0003]
As another technique, as shown in FIGS. 8 and 9, a hanging bag 103 is sewn on the back side of the outer skin 101, and a wire 107 is inserted into the hanging bag 103, The tip is bonded to a synthetic resin plate protector 104 together with a wire 107 with a C-ring 105, and the protector 104 is hooked to an insert wire or a trim wire 106 embedded in a pad 110 inside the seat to suspend the skin 101. The structure is known.
[0004]
However, in each of the above conventional techniques, it is necessary to embed an insert wire and engage the insert wire and the steel wire with an ohmic clip or a C-ring. In such a process of hanging on the insert wire, it is necessary to work from the bottom surface side of the sheet, and there is a disadvantage that the work efficiency is very poor and the work efficiency is poor.
[0005]
For this reason, techniques using planar fasteners have been proposed. That is, a seat suspension pattern is formed as a groove, a surface fastener is disposed in the groove, and the surface fastener is also attached to the surface of the surface material joined to the surface fastener. The suspended pattern was formed by joining the planar fasteners of the material.
[0006]
[Problems to be solved by the invention]
In the prior art as described above, a technique has been proposed in which a groove portion that has been preliminarily matched to the pattern shape is formed at the time of molding the cushion material, and the adhesive and fastener are joined after molding the cushion material. In the technique using the agent, a step of applying an adhesive to the groove portion is necessary, and it is difficult to join the planar fastener and the cushion material.
[0007]
When joining the surface fastener of the skin material and the surface fastener of the cushion material, the surface fastener that is integrally foamed with the cushion material has a bonding force on the cushion material side formed by integral foaming, and If the positional deviation of the skin material is to be corrected from the difference between the bonding force with the surface fastener, the bonding force between the surface fasteners is larger than the bonding force between the cushion material and the surface fastener, and FIG. As shown, there is an inconvenience that the planar fastener integrally formed on the cushion material side is peeled off, and it is practically impossible to correct the positional deviation.
[0008]
Therefore, careful work is required, and there is a disadvantage that skill and experience are required, and work efficiency is poor. In addition, when force is applied from the skin material side during movement of the buttocks during use, the surface fastener is peeled off from the cushion material due to the movement of the skin material, causing the skin material to float, etc. This is inconvenient in that it does not meet its original purpose and the appearance is deteriorated.
[0009]
An object of the present invention is to eliminate the above-mentioned inconvenience, and in a seat using a planar fastener for suspending a planar fastener formed by integral foam molding, a combination for joining a skin material and a cushion material. It is an object of the present invention to provide a suspended planar fastener-integrated foaming mold that can be prevented from peeling off the corner portion of a planar fastener by being attached to a skin material during attachment, correction, or use.
[0010]
Another object of the present invention is to provide a seat using a surface fastener for suspension and a suspension surface shape for preventing the end of the surface fastener from being peeled off from the cushion material without increasing the number of steps and cost. The object is to provide a fastener-integrated foaming mold.
[0011]
A further object of the present invention is to provide a suspension-type planar fastener-integrated foaming mold that can prevent urethane liquid from entering the fastener surface and thereby deteriorating the joining function of the planar fastener.
[0012]
[Means for Solving the Problems]
A suspension-type planar fastener-integrated foaming mold according to the present invention includes a first mold that forms a cavity mold and a second mold that closes the first mold, and the first mold has a predetermined shape. The pattern groove portion is formed by projecting toward the cavity side, and the surface for fastening is formed by integrally injecting the surface fastener by injecting resin by placing the bonding surface of the surface fastener on the mold side in the pattern groove portion. In the fastener-integrated foaming mold, the second metal mold is formed with a fastener presser projecting toward the first metal mold outside the end of the pattern groove, and the fastener presser includes the first metal mold and the second metal mold. When the mold is clamped, the planar fastener arranged extending from the end of the pattern groove is pushed into the mold side so as not to come into contact with the mold by the fastener pressing of the second mold. It is characterized by becoming.
[0013]
