Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a headrest that is molded by inserting a frame and injecting foamed resin into the inside of the outer skin.

[Prior Art] A conventional headrest will be explained with reference to FIGS. 3 and 4. In the figure, 1 is the outer skin of the headrest, 2 is a pipe-shaped stay 2a, and this stay 2
A headrest frame material 3 is made of foamed resin such as urethane. The outer skin 1 is an impregnable skin material,
For example, it is made of breathable cloth and is sewn into a rectangular shape as shown in Figure 3.
The bottom surface 1a has a frame insertion portion 4 consisting of a slit 4a for inserting the frame 2b and holes 4b for protruding the stay 2a.

In the above configuration, the headrest frame material 2 is inserted from the frame insertion part 4 of the outer skin 1, and the holes 4b, 4b are inserted.
The stays 2a, 2a are made to protrude from. This skin 1
The stay 2a is inserted into the insertion hole 5a of the upper mold 5, and the stay 2a is fixed at a predetermined position by the fixing member 5b, and the combination of the headrest frame material 2 and the upper mold 5 is attached to the upper mold 5. Next, the outer skin 1 attached to the upper mold 5 is placed in the lower mold 6, and the upper mold 5 is attached so as to close the opening of the lower mold 6 and clamped by a clamping means (not shown). In this state, that is, in the state shown in FIG. Inject into the interior 1b of the outer skin 1. By foaming and hardening the injected liquid foam resin 3, the outer skin 1 is molded into a shape along the walls of the upper mold 5 and lower mold 6, and the head rest frame material 2 is fixed, so that the head rest is molded. be done.

[Problem to be solved by the invention] Since the conventional headrest is constructed as described above, the foamed resin 3 leaks from the frame insertion part 4 to the surface side of the outer skin 1, causing the frame to leak as shown in FIG. The foamed resin 3a adheres to the vicinity of the insertion portion 4, resulting in poor appearance. Further, since the outer skin 1 is made of an impregnated skin material, there are problems in that the adhered foamed resin 3a is difficult to remove and the workability is poor.

This invention was made in order to solve the above-mentioned problems, and the purpose is to obtain a head rest that is easy to remove foamed resin attached to the surface side, has good workability, and has a good appearance.

[Means for Solving the Problems] In the head rest according to this invention, at least the bottom surface of the outer skin near the frame insertion portion is formed of a non-impregnable resin that is not impregnated with the foamed resin.

[Function] The head rest of this invention is made of a non-impregnable resin that is not impregnated with the foamed resin at least at the bottom of the outer skin near the frame insertion part, so that even if the foamed resin leaks and adheres to the surface of the outer skin, it will not be impregnated. It does not impregnate the outer skin, and the attached foamed resin can be easily removed.

[Example] An example of this invention will be described below with reference to FIGS. 1 and 2. Components that are the same as those in FIGS. 3 and 4 are designated by the same reference numerals, and their explanation will be omitted. In the figure, 8 is a bottom member provided on the bottom surface 1a of the outer skin 1. This bottom member 8 is made of a non-impregnable resin, such as vinyl chloride, which is not impregnated with the foamed resin 3. 4a and holes 4b, 4b, and is attached by high frequency missing adhesive 9 as shown in FIG. This headrest is molded using the same process as the conventional method.

With the above configuration, even if the foamed resin 3 leaks from the frame insertion part 4 and adheres to the surface side of the bottom member 8,
Since it is a non-impregnable resin, the foamed resin 3 attached to the bottom member 8 without being impregnated can be easily removed.

In addition, in this embodiment, the bottom surface 1a of the outer skin 1
However, the entire surface of the bottom surface 1a may be made of the bottom member 8, that is, a non-impregnable resin, and the bottom member 8 is attached by high-frequency sewing adhesive 9, but it is not necessary to use sewing or adhesive. It can also be installed by twisting it.

In addition, in the above embodiment, the headrest frame material 2 is shown as having two stays 2a, 2a provided on the frame 2b, but it is also applicable to a type of headrest in which one stay 2a is provided in the center of the frame 2b. Of course it is possible.

[Effects of the invention] As described above, according to this invention, the headrest is made of a non-impregnated resin that is not impregnated with the foamed resin at least in the vicinity of the frame insertion part on the bottom surface of the outer skin, thereby preventing the foamed resin from leaking. Even if the foamed resin adheres to the surface of the outer skin, the adhered foamed resin can be easily removed, improving workability and appearance.

Claims (1)

[Scope of utility model registration request] It has a headrest frame material composed of a stay and a frame that holds the base of the stay, and the frame side of the headrest frame material is inserted into a frame provided on the bottom surface of a hollow headrest outer skin made of an impregnable skin material. The headrest is molded by inserting the foamed resin into the inside of the outer skin, and is characterized in that at least the bottom surface of the outer skin near the frame insertion part is made of a non-impregnable resin that is not impregnated with the foamed resin. Head rest.
