Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a front seat headrest of an automobile.

<Prior art> As shown in FIGS. 6A and 6B, in a conventional automobile front seat headrest, a stay 3 fixed to the headrest main body 2 is inserted into an insertion hole 4 provided on the upper end surface of the backrest. structure and
As shown in FIGS. 7A and 7B, a tower portion 5 is provided protruding from both sides of the upper end of the backrest 1, and a guide portion 6 provided vertically on the inner surface of the tower portion 5 is provided protruding from both sides of the headrest body 2. A structure in which an engaging portion (not shown) is slidably guided is known.

<Problems to be solved by the invention> In the case of the conventional structure shown in FIG. 5 above, when the headrest main body 2 is set in the raised position as shown in FIG. 6B, the stay 3 is exposed, which is unfavorable in terms of appearance. . In addition, in the case of the conventional structure shown in FIG. 7, the headrest main body 2 does not have a stay, and the problem of the structure shown in FIG. It is a structure that cannot be used. Therefore, when there is no person sitting in the assist seat and there is a person sitting in the rear seat, the head rest main body 2
Even if you try to remove it, it won't work and you won't be able to see the front.

<Means for Solving the Problems> The present invention solves the above-mentioned conventional problems, and its structure is such that a protrusion is formed at the center of the upper end of the backrest, and both sides of this protrusion are A long groove is provided in the vertical direction, a cylindrical support is provided continuous to the lower end of the long groove, and a notched recess corresponding to the protrusion is provided in the headrest main body to form both left and right legs, which are inserted through the long groove. A stay inserted into the support projects from the inner walls of the left and right legs, is cranked along the legs, and extends from the lower ends of the legs.

<Function> In the present invention, by fitting both the left and right legs of the headrest main body to both sides of the convex part at the center of the upper end of the backrest, the stays are inserted into the long grooves and fitted into the supports to attach the headrest main body.

<Example> An example of the present invention will be described below based on FIGS. 1 to 5. In FIG. 1, 10 is a backrest. A protrusion 11 is formed at the center of the upper end of the backrest 10, and long grooves 13 in the vertical direction are recessed in both side surfaces 12 of the protrusion 11, and a cylindrical support 14 ( (see FIGS. 2 and 5). The specific structure of the long groove 13 and the support 14 is shown in FIG. 2, and the support 14 is inserted and fixed into a hole 16 formed in a frame 15. The long groove 13 is formed by a member of the side shield 20 which is made of plastic and is formed into a U-shaped cross section. The side shield 20 is inserted through the slit 19 and fixed to the base 17 with screws.

21 is the headrest main body. This headrest main body 21 is provided with a cutout recess 22 corresponding to the protrusion 11, and the cutout 22 forms legs 23 on the left and right sides. As shown in FIG. 4, each leg 23 has a stay 24 extending from the lower end of the leg 23, which protrudes from the inner wall of the leg 23, is cranked along the leg 23, and is offset inward from the center of the leg 23. It is provided.

Since the present invention has the structure as described above, by inserting the stays 24 of the headrest main body 21 into the long grooves 13 of both side surfaces 12 of the convex part 11 and inserting them into the supports 14, the legs 23 can be attached as shown in FIG. are fitted into both side surfaces 12 of the convex portion 11, and the headrest main body 21 is attached to the upper end of the backrest 10 so as to be vertically adjustable. In this installed state of the headrest main body 21, the stay 24 is connected to the long groove 1 that is closed by the leg 23.
3, so it is not exposed to the outside.

<Effects of the invention> As described above, according to the invention, long grooves in the vertical direction are recessed on both sides of the protrusion formed at the center of the upper end of the backrest, and the stay of the headrest body is inserted into the lower end of the long groove. The headrest main body is provided with notched recesses corresponding to the protrusions, legs that fit on both sides of the protrusions, and stays that protrude from the inner wall of the legs and are crank offset. Therefore, it is of course possible to attach and detach the headrest main body, and when it is installed, it is firmly attached by the fitting of the legs and the support of the stay, and the stay is concealed by the legs, which improves the appearance. have.
