(Prior Art) Generally, this type of headrest includes a headrest main body made of a headrest frame fixed on a headrest stay extending from the seat back side and a pad material arranged around the headrest frame;
It is composed of a skin material covering the outer periphery thereof.

By the way, in the headrest having the above-mentioned configuration, the skin material enclosing the pad material constituting the headrest main body is usually placed over the headrest main body from above, and then the opening edges are overlapped from both sides and fastened with a fastener. The so-called bellow fastener method is used. Also, there is a method called the undercover method, in which the opening edges of the skin material described above are joined with ohm clips, etc., and then this joint is covered with an undercover that is screwed to the lower part of the headrest body. is also known.

(Problems to be solved by the invention) However, according to the above-mentioned bellow fastener method, the work is not only troublesome and complicated, but also the overlapping part of the fastener at the lower end of the headrest is exposed to the outside and looks unsightly. Furthermore, the above-mentioned overlapping portions could not be properly joined, and variations were likely to occur, and there was a risk that the appearance would be impaired.

In addition, with the undercover method, not only is the work of fixing the undercover screwed to the lower end of the head rest troublesome, but the parts of the undercover other than those screwed tend to float, resulting in an unsightly appearance. It was hot.

The present invention was developed in view of the above circumstances, and the opening edge of the skin material covered with the outer periphery of the headrest frame and pad material constituting the headrest main body has been developed without unnecessary fixing tools or troublesome tools. To provide an inexpensive headrest which can be easily and appropriately fixed without any work, greatly improves workability, and has a configuration with good appearance.

(Means for Solving the Problems) The headrest according to the present invention has an undercover on the lower surface of the headrest body made of a headrest frame and a pad material, which holds the opening edge of the skin material covered on the outer periphery. A recess into which the undercover is fitted is formed, and a locking groove into which the side edge of the undercover is engaged is formed in the side wall of the recess, and the opening edge of the skin material is connected to the side wall of the undercover. It is adapted to be held and fixed by engaging the locking groove in the recess together with the side edge.

(Function) According to the present invention, when covering and fixing the skin material to the headrest main body, the opening edge of the skin material can be fixed with one touch at the same time as the undercover that is fitted into the recess formed on the lower surface of the headrest main body. It can be fixed.

(Example) Hereinafter, the present invention will be described in detail using an example shown in the drawings.

1 and 2 show an embodiment of the headrest according to the present invention, and in these figures, the headrest, which is designated as a whole by the reference numeral 1, is a headrest stay 3 extending from the upper part of the seat bag 2. A headrest main body 6 consisting of a headrest frame 4 disposed at the upper end and a pad material 5 attached around the headrest, and a skin material 8 having an opening 7 and covering the outer periphery of the main body 6 from above.
and an undercover 9 that is attached to the lower part of the headrest main body 6 while holding the edge of the opening 7 of the skin material 8. In the figure, 3a is a holder that holds the headrest stay 3 at the upper end of the seat bag 2, and the headrest stay 3 and the headrest frame 4 are connected and fixed by appropriate fixing means.

Now, according to the present invention, in the headrest 1 having the above-described structure, a recess 10 into which the undercover 9 is fitted and fixed is formed on the lower surface of the headrest main body 6, and one side of the undercover 9 is inserted into the recess 10. The undercover 9 is attached to the side wall portion 10a.
A locking groove 11 into which one side edge 9a is engaged is formed in the headrest frame 4, and an edge of the opening 7 of the skin material 8 is connected to the other side edge 9b of the undercover 9.
It is locked by a claw part 12 as a locking part provided on the side,
A further feature is that the remaining portion of the undercover 9 is held and fixed by being engaged with the locking groove 11 in the recess 10 together with the one side edge 9a of the undercover 9.

Here, 4a in the figure is a hole formed in the headrest frame 4. Further, the undercover 9 described above can be moved vertically up and down on the headrest stay 3 through a hole (not shown) formed in a part thereof, and furthermore, the undercover 9 is The claw portion 12 is appropriately formed on a side edge other than the one side edge 9a that is locked in the locking groove 11, and is configured to lock the opening edge of the skin material 8 over substantially the entire circumference. This is what has been done. In this case, the skin material 8
It will be easily understood that a hole 8a is formed at the edge of the opening to correspond to the claw 12.

According to such a configuration, when covering and fixing the skin material 8 to the headrest main body 6, the edge of the opening 7 faces into the recess 10, as shown in FIG. By fitting the undercover 9 into the recess 10 in this state, the side edges 9a and 9b of the undercover 9 can lock the opening edge of the skin material 8 and can be fixed to the main body 6 side at the same time with one touch. be. Therefore, the workability during molding of the headrest 1 can be greatly improved, and the undercover 9 formed by locking the edge of the opening 7 of the skin material 8 can be accommodated in the recess 10 on the lower surface of the main body 6. Therefore, there is no problem such as spoiling the appearance of the headrest 1 as in the conventional case, and there is an advantage that the design effect can be exhibited.

Further, according to the above-described configuration, the recess 10 is formed below the head rest main body 6 so as to surround the head rest stay 3, and this recess 10 holds the head rest stay 3 protruding from the upper end of the seat back 2. Since the holder 3a and the like can be accommodated when the headrest 1 is lowered, the gap that occurs between the lower surface of the headrest 1 and the upper end surface of the seat back 2, which has been a problem in the past, is eliminated and the appearance is improved. is possible. That is, in the configuration according to the present invention, when the headrest 1 is lowered to the lowest level and brought into close contact with the seat bag 2, the holder 3a becomes an obstacle and creates a gap, and the headrest 1 is not forced down. This can solve the problem of the surface of the seat back 2 being warped in a wavy manner, impairing its appearance, and has a great practical effect. Of course, in this case, the lock release lever etc. for raising and lowering the headrest 1 in the vertical direction may be provided at a location other than the upper end of the seat back 2, or simply attached to the headrest 1.
It is sufficient to adopt a ratchet configuration in which the unlocked state can be obtained by pulling the lock upward.

Note that the present invention is not limited to the structure of the embodiment described above, and the shape and structure of each part may be modified and changed as necessary. For example, various modifications can be made to the shapes of the headrest frame 4 and pad material 5 constituting the headrest main body 6, and it goes without saying that the same applies to the other constituent parts.

(Effect of the invention) As explained above, according to the headrest of the present invention, a recess into which the undercover for holding the opening edge of the skin material is fitted is formed on the lower surface of the headrest main body, and inside this recess. A locking groove is formed in the side wall portion of the undercover into which the side edge of the undercover is engaged, and the opening edge of the skin material is held and fixed by being engaged with the side edge of the undercover in the locking groove in the recess. Therefore, in spite of the simple and inexpensive structure, when covering and fixing the skin material to the headrest main body, the opening edge is fixed with one touch at the same time as the undercover, and this allows molding. In addition, the undercover can hold and secure the opening edges of the skin material evenly over the entire circumference, and accommodate them in the recess on the bottom surface of the headrest. As a result, there are various excellent practical effects such as eliminating the conventional problem of spoiling the appearance, and greatly improving the quality of the product and its design effect.

Further, according to the present invention, since a recess is formed on the lower surface of the headrest, this recess is used to accommodate a holder, etc. for holding the headrest stay on the upper end surface of the seatback, so that when the headrest is lowered to the lowest level, the seatback can be moved. It can be brought into close contact with
This also has the advantage of providing a good appearance since no gap is created between the two.
