Description

[Detailed Description of the Invention] The present invention relates to a frame structure of a headrest used in a seat.

As schematically shown in FIG. 1, the frame structure of a conventional headrest is such that a metal plate is press-molded into an appropriate shape to form a frame body 2, and a headrest formed in an inverted U shape is formed on this frame body 2. The stay 3 is fixed by welding or other methods to form the frame 1 of the headrest.

However, when manufacturing different headrests, the frame body 2 and headrest stay 3 of the headrest must be changed, which complicates quality control and makes it difficult to arbitrarily change the size and strength of the frame body 2. It had some drawbacks.

The purpose of the present invention is to provide a frame structure of a headrest that is extremely economical and allows various different headrest frames to be obtained by combining a headrest frame main body and a headrest stay. It will become clear from the detailed explanation given below.

2 and 3 respectively show the basic structure of the frame structure of the headrest according to the present invention, and in this embodiment, a case where one cylindrical headrest frame body 12 is used is shown. The side walls 1 at both ends of the frame body 12 are shown in FIG.
A through hole 14 is formed approximately at the center of each of the holes 2a. A pair of connecting members 15 are formed so as to protrude outward from the side wall 12a of the frame body 12,
In this embodiment, the pair of connecting members 15 are continuous rods 16 that respectively pass through the through holes 14 of the frame body 12.
A threaded portion 15a is formed at both ends of the connecting rod 16.

The headrest stay 13 has a fitting hole 17 formed in its upper part, and an uneven part 18 formed in its lower part so that it can be attached to a seat bag frame (not shown) with vertical position adjustment. Therefore, the series 16
The connecting rod 16 is inserted into the frame body 12.
The headrest stay 13 is fitted into the threaded portions 15a formed at both ends of the rod through the fitting hole 17, the washer 19 is attached from the outside, and the nut 20 is screwed into the threaded portion 15a of the connecting rod 16. As a result, a headrest frame 11 is formed.

Incidentally, cans and open cans for youth, soft drinks, etc. can be used for the frame main body 12, and when a open can is used, the side wall 1 as shown by reference numeral 22 in FIG.
Use No. 2 reinforcing plate. The use of open cans helps conserve resources and reduces costs.

A first embodiment of the present invention is shown in FIGS. 4A and 4B, and this headrest frame 11 includes a plurality of the cylindrical headrest frame bodies 12 arranged in series, and the length of the continuous rod 16 It has the same structure as the first embodiment, except that the length is formed to be longer in accordance with the length of the plurality of frame bodies 12, that is, in accordance with an integral multiple of the length of the frame bodies 12. As shown in FIG. 4B, by making the length of the frame body 12 small, the length of the headrest frame 11 in the width direction can be changed extremely easily, and headrest frames of various lengths can be made. You can get 11.

FIG. 5 schematically shows a second embodiment of the headrest frame according to the present invention, and this headrest frame 11 has a cylindrical frame body 12.
are arranged in parallel, and a lower fitting hole 17b is further formed in the headrest stay 13 at a predetermined interval below the upper fitting hole 17a. The threaded portion 15a of the connecting rod 16 similar to the above-mentioned embodiment, which protrudes outward from the side wall 12a of the frame body 12, is inserted, and the nut 20 is screwed into the threaded portion 15a of the connecting rod 16 from the outside to secure the head. A rest stay 13 is fixed to the frame body 12. Also in this embodiment, as shown in FIGS. 4A and 4B, a plurality of frame bodies 12 arranged in series can be used.

FIG. 6 schematically shows a third embodiment of the present invention, and parts corresponding to those in FIG. The frame 11 is the frame body 12
A triangular mounting plate 25 is fixed between the headrest stay 13 and the headrest stay 13.
5 has a pair of through holes 25a and 25b formed at positions facing the pair of fitting holes 17a and 17b of the headrest stay 13, respectively, and a third through hole 25c, and a third through hole 25c. Holes 25a and 25
After fitting the mounting plates 25 to the threaded portions 15a of the connecting rods 16 of the pair of connecting members 15 through the screws 15b, the head rest stays 13 are fixed to the connecting members 15, so that the mounting plates 25 are fixed at the same time. Furthermore, by attaching the third frame main body 32 to the third through hole 25c via the connecting member 15, the headrest frame 11 in which the first to third frame main bodies 12 and 32 are arranged in parallel can be formed. This embodiment has the same structure as the second embodiment except that it can be obtained. Also in this third embodiment, it is possible to use a structure in which a plurality of frame bodies 12 are arranged in series, and by deforming the mounting plate 25, an even larger number of frame bodies 32 can be attached. It will be clear that the shape of 11 can be changed quite easily.

The above is an outline of one embodiment of the frame structure of the headrest according to the present invention. According to such a structure, the combination of the headrest frame main body and the headrest stay, and furthermore, the assembly of these and the mounting plate. By combining various headrest frames, it is extremely easy to obtain various headrest frames, and since the frame body is formed in a cylindrical shape, it receives impact evenly from any direction. It is possible to obtain a frame structure of the headrest that has excellent stability and is extremely economical because the deformation is constant even when subjected to impact from above.
