Abstract

PURPOSE:To produce efficiently a breathable head restraint, by putting a parison on a netlike body, clamping it in molds, carrying out blow molding, and cutting off part of the molded itsm where the netlike body is located. CONSTITUTION:A stay 20 to which a netlike body 12 will be attached is arranged vertically. Then a tubular parison 30 is melted and extruded from a die of a blow molder from above the stay 20 thereby covering the parison 30 over the stay 20. Thereafter, molds 24a, 24b are closed to clamp the melted parison 30, air is forced into the parison 30 to be expanded thereby bringing the parison in firm contact with the inner surfaces of the cavities 26a, 26b, so that a preparatory molded item having a profile similar to the intended head restraint 14 and possessing the stay 20 inserted therein is formed. Then the central section 34 is cut off from the preparatory molded item with the netlike body 12 left, so that the head restraint 14 having an opening 10 at the central section thereof can be obtained.

る。PRIOR ART Seats used in passenger cars, light trucks, and other vehicles primarily have a seat system that prevents the occupant's head (hereinafter referred to as a vehicle occupant) from tilting back to prevent neck damage in the event of a rear-end collision. A ``pillow'' is attached to the top of the seat backrest in order to provide a rest for the vehicle occupant's head while the vehicle is in operation. Regarding this “pillow”,
In the automobile terminology defined in the Japanese Industrial Standards, it is written as "Head Retraints" J, and it is generally called "Head Retraints" in the field, so this specification also uses this "Head Retraints". In principle, the terminology shall be followed as ``head restraint,'' and to avoid redundancy, it may also be simply referred to as ``pillow.''

A head restraint with a unique design was proposed. However, as shown in FIG. 5, the skin material used for the Herad restraint has a structure in which an opening 10 is transparently provided in the center and a breathable member 12 is exposed through the opening. Therefore, it is not easy to manufacture this skin material, and a rational manufacturing method has been sought.

れる。(1) The step of locking the breathable member (especially in FIGS. 1 and 2) The seat mounting stay 20 inserted into the head restraint 14 is finally hollowed out as shown in FIG. The cushion material 1゛8 is inserted into the skin material 16.
It is embedded in the pillow body and is attached to the top of the seat backrest to support it. This stay 20 is made of a metal hollow tube or a solid rod-shaped body, and is known in itself, but in this case, an opening 10 is transparently provided at approximately the center of the head restraint body. Therefore, the stay is arranged at a position that avoids the opening 10. For example, as shown in FIGS. 1 and 6, the stay 20 includes a lip-shaped portion 20a that is inserted into the head restraint 14 and functions to support and reinforce the pillow body, and A pair of attachments that are an extension of the portion 20a and are inserted into the top of the seat backrest are the pillar portions 20.

It is locked and fixed by the locking tool 22 of. As shown in FIGS. 1 to 3, the air permeable member 12 is preferably a flat mesh body with a predetermined mesh size, and is made of, for example, polypropylene resin, hard vinyl chloride resin, glass fiber reinforced acrylonitrile-styrene copolymer. The material is general plastic such as composite resin or reinforced plastic, but it may also be made of metal wire (for example, stainless steel wire) that has been subjected to rust prevention treatment and is knitted into a net-like body if necessary. Furthermore, as the breathable member 12, in addition to the above-mentioned net-like body, a so-called punching board in which a large number of holes are formed in a plate-like body, and a lattice-like body consisting of a large number of lattices arranged at predetermined intervals are preferably used. .

24b is closed to clamp the molten parison 30, and the parison 30 is expanded by injecting air through the air supply pipe. By closely contacting the inner surface of the stay 2, the outer contour of the head restraint 14 is formed as shown in FIG.
A preformed body (skin material 16) having 0 inserted therein is molded. Note that both molds 24a and 24b allow the parison 30 and the net-like body 12 to pass through the hollow penetrating protrusion 2 when the mold is closed.
Since they are clamped by the respective open end surfaces of 8a and 28b, the preforms are brought into close contact with each other at the clamped portions. Therefore, if air is blown into the parison 30 in this state.

The preformed body (skin material 16) is firmly clamped by the abutting open end surfaces of b, and the central part 34 is cut off leaving the net-like body 12, or the central part 34 is cut off with an appropriate blade. As a result, as shown in FIG. 5, an opening 10 is formed approximately in the center of the head restraint 14. In this way, the skin material 16 in which the air-permeable member 12 is stretched over the opening 10 is obtained. Note that, if necessary, paris removal is performed at this time.

By blowing, a hollow skin material for a head restraint, which has an opening in the center and has a breathable member interposed in the opening, is manufactured. In other words, the present invention appropriately applies the blow molding method that is often used in the production of hollow plastic bodies to create a head restraint in which an air permeable member such as a mesh is provided in the opening, which was generally difficult to produce in the past. This has made it possible to easily and rationally manufacture the skin material.

The parison is pressed between a pair of molds each having a recess. Air is blown into this compressed parison to expand the parison and bring it into close contact with the inner surface of the cavity to obtain a preformed skin material, and then the center portion of the preform is removed to improve the air permeability. A method for manufacturing a skin material used for a head restraint, which is characterized by exposing its members to the outside.
