DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headrest for a vehicle seat and, more particularly, to a headrest frame, a headrest stay projecting below the headrest frame, and a skin material attached to the headrest frame. And a headrest for a vehicle seat comprising the following.

[0002]

2. Description of the Related Art Generally, a headrest of a vehicle seat is
The vehicle includes a headrest frame, a headrest stay protruding below the headrest frame, and a pad material attached to the headrest frame and a skin material covering the pad material. In recent years, in order to reduce the weight of a vehicle seat, there is also a vehicle seat in which a pad material is omitted and a skin material is simply stretched on a seat frame such as a pipe frame.

[0003] Japanese Patent Application Laid-Open No. 6-57579 discloses that
A multi-layer woven or knitted fabric comprising a bulky woven knitted fabric having a thickness of 5 mm or more, which is made up of a double-sided double-sided base fabric and a connecting yarn for connecting the double-sided double-sided base fabrics, is disclosed. The skin material made of the bulky three-dimensional structure woven or knitted fabric has a sufficient cushioning property even if the pad material is omitted.

As shown in FIG. 5A, a skin material 3 of a headrest 1 of a conventional vehicle seat is formed in a bag shape, and a lower end opening portion 5 of the skin material 3 is formed with a lower end 6a of a front side skin material 6. The lower end 7a of the back side skin material 7 is attached to the locking member 8, respectively. The lower end 7a of the back skin material 7 is fixed to the locking member 8 by sewing or the like, and the locking piece 6b is attached to the lower end 6a of the front skin material 6, and the locking piece 6b is engaged with the locking member 8. The lower end opening 5 of the skin material 3 is closed by being inserted into and locked by the stopper 8a.

[0005]

In the conventional vehicle seat headrest 1, the lower end opening 5 of the skin material 3 is formed by the lower end 6a of the front skin material 6 and the lower end 7a of the back skin material 7. Since the skin material 3 itself is attached to the locking member 8, the skin material 3 itself is entirely displaced together with the locking member 8, and the lower end portion 6 a of the front skin material 6 of the skin material 3 and the back skin material are removed. There is a problem that the terminal line at the lower end 7a of the terminal 7 cannot be determined. Further, it is necessary to insert and lock the locking piece 6b to the locking portion 8a of the locking member 8 while applying tension to the lower end portion 6a of the front side skin material 6. If the strong tension is applied, the skin material 3 is displaced. Poor workability,
Further, as shown in FIG. 5B, when a strong load is applied to the front skin material 6 of the skin material 3, there is a possibility that the locking pieces 6 b may come off from the locking portions 8 a of the locking member 8.

SUMMARY OF THE INVENTION It is an object of the present invention to align the terminal lines at the lower end of the front skin material and the lower end of the back skin material at desired positions without the risk that the skin material itself will shift as a whole. There is no danger that this terminal line will be displaced, it is possible to easily perform the locking work while applying tension to the skin material, it is possible to improve the appearance, improve the cushioning property and the feel, and reduce the weight An object of the present invention is to provide a vehicle seat headrest which is economical and can be assembled, does not require a pad material of a main part, can reduce the thickness of the headrest, and can improve the efficiency of assembly work.

[0007]
