Abstract

PURPOSE: Provided is a structure of male velcro tape secured to the side of a car seat pad as opposed to female velcro tape formed at the stitched portion of a seat cover, and a metallic pattern for molding a car seat cover. CONSTITUTION: The male velcro tape(20) secured to the side of a car seat pad(40) as opposed to female velcro tape formed at the stitched portion of a seat cover(10) includes an iron powder-containing cover on the surface of a hook(22), and a non-woven fabric(21) adhered to the rear surface of a hook board(23). The metallic pattern for molding the seat pad(40) includes a permanent magnet inside the frame of a lower mold. Therefore, the iron powder-containing cover adheres to the permanent magnet mounted on the frame of the lower mold. Also, urethane resin in the mold is permeated into the non-woven fabric(21) that is adhered to the rear surface of the hook board(23), thereby ensuring the male velcro tape(20) to be firmly secured to the seat pad(40).

Description

Velcro tape and seat pad mold for car seat pad {car-seat-cover for velcro-tape and car-seat-pad for metallic pattern}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a male velcro tape fixed to a seat pad side of a velcro tape for attaching a seat cover to a seat pad configured in a vehicle chair and the like, and a mold for molding the seat pad.

The present invention is an improvement of Patent No. 349299 (Method for Forming a Pad for Vehicle Seat), filed by the applicant of the present invention and patented on Aug. 6, 2002.

In general, urethane resin was injected into a mold and foamed to make a urethane foam seat pad. Then, the seat cover of the fabric or leather material was wrapped in a seat pad to make a sheet.

Conventionally, the seat cover is fixed to the seat pad by using a Velcro tape to attach the seat cover when the seat pad is molded. The method is as follows.

When the seat pad was molded, Velcro tape was placed in the frame installed in the mold and urethane resin was injected and foamed to form the seat pad fixed with Velcro tape.

The urethane resin did not adhere well to the back of the hook board of the Velcro tape, so that the Velcro tape was not firmly fixed to the seat pad after urethane resin was foamed.

In addition, if the curved part of the sewing part of the seat cover has a lot of curvature, when inserting the male Velcro tape into the frame installed in the lower mold to correspond to the sewing part, the male Velcro tape is lifted or distorted and the urethane resin is injected into the mold. There was a disadvantage that a defect occurs when manufacturing the seat pad.

The present invention was developed in view of the conventional problems, and an object of the present invention is to insert a male Velcro tape into a frame installed in a seat pad mold so as to correspond to a female Velcro tape formed on the sewing portion of the seat cover, without lifting or twisting the frame. In close contact with the lower part, the urethane resin is injected and foamed into a mold to provide a seat pad Velcro tape and a seat pad mold for a vehicle chair in which a male Velcro tape is firmly fixed to the seat pad.

Features of the present invention for achieving the above object in the configuration of the male Velcro tape 20 is attached to the seat pad 40 side of the Velcro tape for attaching the seat cover 10 to the seat pad 40 of the vehicle chair ,

On the surface of the hook 22 of the male Velcro tape 20, a cover 24 containing iron powder is attached,

Velcro tape for seat pads, characterized in that the non-woven fabric 21 is bonded to the back of the hook substrate (23),

In the internal structure of the lower mold 30 of the mold for forming the seat pad 40 to which the seat cover 10 is attached,

It is configured to be provided with a seat pad mold, characterized in that the permanent magnet 32 is installed in the frame 31 of the lower mold (30).

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, a general vehicle chair seat includes a seat pad 40 formed of urethane resin and a seat cover 10 covered on the outside of the seat pad 40.

Of course, the sheet made of the above-described configuration is a known technical idea.

Here, the most important feature of the present invention relates to a mold in which the Velcro tape and Velcro tape for seat pad, which are firmly fixed at the correct position during sheet pad molding, are brought into close contact with the frame of the mold.

As shown in Figure 2, the hook 22 of the male velcro tape 20 of the velcro tape, which is usually composed of two types of females and males, is formed by the urethane resin while the urethane resin is foamed, and the hooks 22 may be generated. ), A cover 24 containing iron powder is attached to the surface of the hook 22 so as to prevent a defect and to stick to the permanent magnet 32 mounted on the frame 31 of the lower mold 30. and,

Urethane resin is injected into the mold on the back of the hook substrate 23 so that the male Velcro tape 20 can be firmly fixed to the seat pad 40 when the seat pad 40 is molded. Attached to the hook substrate 23 is a configuration.

Wherein the non-woven fabric 21 can be used as a variety of cloth material as needed, and firmly adhered using a hot melt (glue) or adhesive to be firmly bonded to the back of the hook substrate (23),

The cover 24 attached to the surface of the hook 22 has an adhesive force enough to fall off the surface of the hook 22 when a predetermined force is applied,

It is natural that the hook 22 may take various forms as necessary, such as a hook form or an anchor form as necessary.

And the male Velcro tape 20 configured as described above and the urethane resin is injected into the upper and lower molds (34, 30) and foamed so as to be located in the correct position when the seat pad 40 is molded as shown in FIG. together,

Inside the lower mold 30, a "┗┛" frame 31 having an upper portion is firmly fixed to the protrusion 33 formed to correspond to the sewing portion 12 of the seat cover 10 by using a screw or the like. On the inner upper surface of the frame 31, a permanent magnet 32 is attached.

An embodiment of the seat cover 10 manufactured using the male Velcro tape 20 and the upper and lower molds 34 and 30 configured as described above is as follows.

As shown in FIG. 4A, when the male Velcro tape 20 is inserted into the frame 31, the cover 24 is inserted into contact with the permanent magnet 32.

In this case, the cover 24 containing the iron powder is closely adhered to each other due to the magnetic force of the permanent magnet 32 installed in the frame 31, so that even if the frame 31 is severely bent, the male is not accurately lifted or twisted under the frame 31. Velcro tape 20 is in close contact.

Subsequently, as illustrated in FIG. 4B, when the upper mold 34 is covered and the urethane resin is injected and foamed, the seat pad 40 is molded according to the internal shape of the upper and lower molds 34 and 30.

At this time, since the urethane resin penetrates the nonwoven fabric 21 of the male Velcro tape 20, the seat pad 40 is molded, and the male Velcro tape 20 inserted into the frame 31 is firmly fixed at the correct position.

The cover 22 is attached to the surface of the hook 22 to prevent the inflow of the urethane resin to prevent the failure of the hook 22 due to the inflow of the urethane resin.

Subsequently, as shown in FIG. 4C, when the upper and lower molds 34 and 30 are removed and the cover 24 attached to the hook 22 surface of the male Velcro tape 20 is removed, the male Velcro tape 20 is removed. The seat pad 40 is firmly fixed to the correct position is completed.

Thereafter, as shown in FIG. 5, when the seat cover 10 is covered with the seat pad 40, the female Velcro tape 11 and the male Velcro tape 20 are attached to the seat pads 10. Is coupled to each other is the seat cover 10 is fixed to the seat pad 40 very simple and tight.

As described above, according to the present invention, when the seat cover 10 is put on the outside of the seat pad 40 and the sewing unit 12 is pressed, the female and male Velcro tapes 11 and 20 are coupled to each other so that the seat cover 10 is provided. Is firmly fixed to the seat pad 40,

Fastening and simple fixing of the seat cover 10 is possible to maximize the working efficiency and at the same time by applying more than a certain force to pull the seat cover 10 because the female, male Velcro tape (11) (20) is separated from each other Washing or post-repair of the seat cover 10 is to be easily solved to solve all the conventional problems is to increase the external competitiveness of the vehicle seat as much as possible.
