2. Description of the Related Art A headrest support for supporting a headrest of an automobile seat or the like, which can be moved forward, is disclosed in, for example, Japanese Utility Model Publication No. 62-64363 and Japanese Utility Model Publication No. 62-63363. As disclosed in Japanese Patent No. 82829, a spherical support is fitted to a spherical seat formed on the head of a headrest support tube, and a pair of spherical bodies elastically springs the opposite side portions of the spherical support in the front-back direction. Some are supported so that they can be rotated.

However, in the conventional headrest support of this type, since the supporting force is not sufficient only by the support of the pair of spheres elastically urged by the spring as described above, the spherical support is closely attached to the spherical seat portion. If it is not possible to obtain a proper support state, the spherical support can be smoothly rotated while it is inserted into the headrest support insertion opening provided on the top of the seat back and used. In addition to being unable to move, the spherical body that rotatably supports the spherical support may fall out due to repeated frequent rotations of the headrest, leaving a problem in durability, and the accuracy in manufacturing each member. Is required, which causes high cost, and the seat edge covering the seat back has a free end at the rim of the headrest support insertion opening. The side of the head that is not made by pressing the skin material from the top and the decorative surface there is also a problem that unsightly become bare.

As shown in FIG. 2, this headrest support is mounted such that the collar portion 2a of the headrest support tube 1 and the upper portion of the support body 4 are exposed from the top of the seat back, and the stay of the support body 4 is mounted. It is basically the same as this type of conventional headrest support in that the stay 21 of the headrest 20 is inserted and supported through the support hole 4a.
In the present invention, the support 4 is rotatable in the front-rear direction by the pins 5 and 5 inserted from the side surface of the head 2 of the headrest support tube 1.
Is characterized in that its exposed end is covered by both leg pieces 6b, 6b of a U-shaped frame-shaped patch member 6 which is laterally fitted to the head portion 2. The leg pieces 6b prevent the pin 5 from slipping off during use, and fix the edge of the seat skin material 22 corresponding to the edge of the headrest support insertion opening to the head 2.

The patch member 6, as shown in FIG.
The headrest support tube 1 is made of the same material or another hard synthetic resin material, and two slightly wider strip-shaped leg pieces 6b, 6b are extended from both ends of the strip-shaped substrate portion 6a at substantially right angles. However, in order to prevent the headrest from coming off during long-term use, the headrest 2 of the headrest support tube 1 is attached to both leg pieces 6.
An adhesive is applied to the inner surface in advance before the assembling with b and 6b fitted from the side, and after being fitted to the head 2 by this adhesive, they are attached and integrated. In addition,
As shown in the figure, if it is assumed that a shallow groove-shaped recess 7 is formed in a portion corresponding to the pin 5 on the inner surface of the intermediate portion of each leg 6b, the recess 7 maintains the non-contact state with the pin 5. The smooth rotation of the support body 4 is ensured, and the pin 5 is surely prevented from slipping out even under a severe use condition for a long period of time. Further, the illustrated patch member 6 has the base plate portion thereof. Seat back 25 at the upper edge of 6a
Is formed in a notch portion 8 having a shape as shown in the figure that sandwiches the rim of the headrest support insertion opening of the seat skin material 22 that covers the top portion of the sheet with the collar portion 2a provided on the upper edge of the head 2. By fixing the edge of the sheet skin material 22 to the head portion 2 and pushing the sheet skin material 22 from above, the side surface of the head portion 2 is not exposed and an excellent appearance can be exhibited.

In the thus constructed structure, as shown in FIG. 4, the headrest support pipe 1 is inserted and fixed in the bracket 24 attached to the seat back frame 23, and the flange portion 2a and the upper portion of the support body 4 are fixed. Only the outside is exposed to the outside, and the stay 21 of the headrest 20 is inserted and supported in the stay supporting holes 1a and 4a for use, and the support 4 is provided with the pins 5, 5 as needed. Is used as a fulcrum to tilt the headrest 20 forward, and the support body 4 is supported by the pins 5 and 5 fitted into the head 2 from above and inserted from the side surface of the head 2. Therefore, the support body 4 does not necessarily need to be rotated along the inner surface of the head 2, so that dimensional accuracy of each member is not required, and smooth rotation is always performed at low cost. Made It is possible to provide a. Moreover, since the outer periphery of the head portion 2 corresponding to the pin 5 on which the support body 4 is fitted is covered with the band-shaped patch member 6 having a U-shaped cross section, even if the headrest 20 is rotated frequently, It does not fall off, and the smooth function of rotating the headrest can be retained forever. Further, a cutout portion 8 for sandwiching the sheet skin material 22 with the flange portion 2a provided on the upper edge of the head portion 2 is formed on the upper portion of the base plate portion 6a of the patch member 6, and the sheet skin material 22 is formed. Since the edge of the head is held fixed to the head 2, the side surface of the head 2 is prevented from being exposed when the sheet skin material 22 is pushed from the upper side, and the design is always excellent. It will have an appearance.

As is apparent from the above description, according to the present invention, the headrest can be tilted forward, and even if the headrest is frequently rotated, the pin that supports the support body is supported. It does not fall off and can exhibit excellent durability, and it also has an excellent appearance because the edge of the seat skin material is not fixed to the head of the headrest support tube and the side surface of the head is not exposed. You will be able to. Further, since each member is not required to have dimensional accuracy, there is an advantage that cost can be reduced. Therefore, the present invention is extremely large in that it contributes to industrial development as a headrest support that eliminates the conventional problems.
