Abstract

PROBLEM TO BE SOLVED: To simply remove a pad from an insert to be easily disjoined and separated from each other by providing a head restraint including a separating resin coating coated on the surface of the insert, a pad foamed in the insert thereon, and a facing integrally fitted on the pad. SOLUTION: In a head restrain 10, an insert 11 includes a pair of stays 14, a separating resin coating 15 is coated on the surface of the insert 11, and further a pad 16 is foamed in the insert 11 from above the coating 15 to form a designated form of designated dimensions. Further, a facing 17 is integrally stretched on the pad 16 by foaming. As the separating resin coating 15, polyethylene is used, and at the time of foaming the pad 16, a pad undiluted solution is foamed without adhering to an A-shaped pipe frame, whereby the pad 16 can be simply removed from the A-shaped pipe frame.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head restraint used for a vehicle seat, and more particularly, to an easily dismantled skin-integrated foam type head restraint.

[0002]

BACKGROUND OF THE INVENTION Head restraints used in automotive seats have pads that are foamed directly into the insert,
Then, the foam is generally made into a skin integral foam type in which the skin is integrally attached to the pad. In this type of head restraint, the pad cannot be easily removed from the insert, the separation of the pad from the insert is very difficult and time consuming, and recycling is labor intensive. It is troublesome.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a head and a head in which a pad can be easily removed from an insert to facilitate separate disassembly of the insert and pad, and that the insert and pad can be easily recycled.
It is in the offer of the restraint.

[0004]

Means corresponding to the object and the operation thereof
An insert having a pair of stays, a release resin film coated on the surface of the insert, a pad foamed on the insert from above the film, and a skin integrally adhered on the pad by the foaming And the release resin coating allows the pad to be easily removed from the insert to facilitate separate disassembly of the insert and pad.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The head restraint of the present invention will be described below with reference to a specific example shown in the drawings. FIGS. 1 to 3 show the present invention used for a front seat of a passenger car. 10 shows a specific example of the head restraint of the present invention.
Then, the insert 11 includes a pair of stays 14, 14, and the releasable resin film 15 is
Further, a pad 16 is foamed on the insert 11 from above the coating 15 to be molded into a predetermined shape and dimensions, and further, the skin 17 is
The foam is integrally adhered on the pad 16.

[0006] The insert 11 comprises a plurality of bars 12 and 13 spaced at appropriate intervals in the vertical direction and the bars 1 and 2.
The pair of stays 14, 14 extending from both sides of the two, 13
Made in an A-shaped pipe frame with Of course, the A-shaped pipe frame 11 is composed of a long U-shaped pipe that can be bent to serve as the stays 14 and 14 and the stay 1.
Made with short straight pipes welded between the 4,14 root sides.

The releasable resin film 15 is made of polyethylene. When the pad 16 is foamed, the pad stock solution is foamed without adhering the pad stock solution to the A-type pipe frame 11 and the pad stock solution is foamed. Pipe frame 1
The pad 16 is easily detachable from the first. The polyethylene coating 15 first preheats the A-shaped pipe frame 11 as shown in FIG.
A pair of stays 14, 14 are gripped by the masking jig 23 and the A-shaped pipe frame 1 is preheated.
1 is moved to a fluidized immersion tank 20, where it is immersed in polyethylene powder 22, and the A-shaped pipe frame 11 is removed from the polyethylene powder 22, and the A-shaped pipe frame 11 is heated. The surface of the A-shaped pipe frame 11 is coated. Of course, in the fluidized immersion tank 20, the polyethylene powder 22 is filled on the perforated plate 21 and air is blown below the perforated plate 21.

The pad 16 is made of urethane foam and its skin 17 is first set in a mold, and then the A-shaped pipe frame 11 is positioned inside the skin 17 and set in the mold, and then the mold is used in the mold. It is usually foamed integrally. Of course, the skin 17 is sewn in a bag shape, set normally in the mold, and integrally adhered to the pad 16 by foaming of the pad stock solution.

Therefore, since the pad 16 is supported by the A-shaped pipe frame 11 without being completely adhered to the A-shaped pipe frame 11 by the polyethylene coating 15, the head restraint 10 is That A
The pad 16 can be easily removed from the pipe frame 11, and the A-shaped pipe frame 11 and the pad 16 can be easily separated and disassembled into the A-shaped pipe frame 11 and the pad 16, respectively. Make it easily recyclable. In this way, the head restraint 10 is provided with easy dismantling, and as a result, can be easily recycled and contribute to effective use of scarce resources.

As will be apparent from the specific embodiments of the present invention described above with reference to the drawings, one skilled in the art to which the present invention pertains will appreciate the subject matter of the present invention. Is the nature of the invention (na
), and are readily embodied in other aspects that are objectively perceived as inherent in them. Of course, the content of the present invention corresponds to the subject of the invention (be commensu).
rate with) and essential for the invention.

[0011]

As will be understood from the above description, the head restraint of the present invention comprises an insert having a pair of stays, a release resin film coated on the surface of the insert, and In the head restraint of the present invention, the pad is formed by the release resin coating because the pad includes a pad foamed into the insert and a skin integrally adhered on the pad by the foam. The insert is supported on the insert from above the coating without being fully adhered to the insert, and the pad is easily removed from the insert, which is easily disassembled to facilitate separate disassembly of the insert and the pad. And pads are easily recyclable and contribute to the efficient use of scarce resources, resulting in vehicle seats It is a very useful and practical me.
