In this head restraint 10, an insert 11 projects a pair of stays 14 and 14 at the bottom, and a pad 12 is formed of resin. Foam molded and supported over the insert 11 and trim covers 13 are provided with front and rear cover end extensions 16, 17 and left and right cover sides in openings 15 for fitting the pads 12. A cover end extension 16 which is sewn into the bag with extensions 18 and 19, before and after it The male component 21 of the fastener 20 is provided on one 16 of the fastener 20, and the female component 22 of the fastener 20 is provided on the other 17 of the front and rear cover end extensions 16, 17. The cover end extensions 16, 17 are joined together and their left and right cover side extensions 18, 19
Are provided with hooks 23, 23, respectively.
The cover side extensions 18 and 19 are stopped by the stays 14 and 14 at 3 and 23, respectively.

[0006] The insert 11 is formed from a steel plate into an open-ended cylinder, and the pair of stays 14, 14 are formed.
Is previously bent from a pipe into a U-shape and welded to its bottom.

[0007] The pad 12 is integrally foamed around the insert 11 from a resin in a predetermined shape, size and thickness.

[0008] The trim cover 13 is sewn to the bag from resin leather, and the opening 15 is opened in the trim cover 13 in a wide rectangular shape. In addition, the trim cover 13 is processed at the lower part of the terminal. The lower gusset extends before and after the opening edge before and after the opening 15.
End extensions 16 and 17 and their openings 15
And left and right cover side extensions 18 and 19 extending to the left and right opening edges, respectively, and
In the terminal processing, the fastener 20 and the hooks 23, 2
We utilize 3.

As the fastener 20, an elongated plate-shaped resin chuck is used. The chuck 20 is composed of the male component 21 and the female component 22 having a length corresponding to the width of the tip of the cover end extension 16, 17. The male component 21 and the female component 22
4, 24 and 25, 25, the male component 21 of which is in front of the cover end extension 1
6, the female components 22 are sewn to the subsequent cover end extensions 17, respectively.
The male and female components 21, 22 can be engaged with each other by crossing the stays 14, 14 at the stay escapes 24, 24 and 25, 25.

The hooks 23, 23 are formed into a plate shape from a resin, and are sewn to the left and right cover side extensions 18, 19 to form the stays 1.
4, 14 can be hooked.

Therefore, beforehand, the pad 12 is integrally foamed around the insert 11 with resin, while
First, because the trim cover 13 is sewn to the bag with resin leather,
The pad 12 is fitted through the opening 15 to cover the pad 12, and then the left and right cover side extensions 18, 19 are provided at the bottom of the pad 12.
And the hooks 23 are hooked on the stays 14, and the right and left cover side extensions 18, 19 are fixed to the stays 14, 14 with the hooks 23, 23. The front and rear cover end extensions 16,17 are then folded over the left and right cover side extensions 18,19 to the bottom of the pad 12 and the stay reliefs 24,24 and 25,25. That stay 1
The female component 22 engages the male component 21 with the female component 22, and the front and rear cover end extensions 16, 17 are joined together by the chuck 20 to allow the head restraint 10 to Finished.

In the head restraint 10, the trim cover 13 can have a wide opening 15 so that it can be adapted to various designs and the pad 12 can be fitted without difficulty. 15 can be easily placed on the pad 12 without damaging the trim cover 1.
The tension acting on the lower gusset 3 is made flat, the work of hooking the hooks 23, 23 on the stays 14, 14 is also performed flatly, and the terminal treatment of the trim cover 13 is facilitated. Workability is improved, mass production is smooth, and the appearance finish is ensured.

FIGS. 4 to 6 show a specific embodiment 30 of the head restraint of the present invention in which a plurality of wrinkles 32, 32, 32, 32 are provided on a front surface 31 and are used for a driver seat of a passenger car. And this head
In the restraint 30, the insert 11 projects the pair of stays 14, 14 at the bottom and the pad 12
Is foamed from resin and the insert 1
1 and supported by a trim cover 13
Is sewn to the bag with front and rear cover end extensions 16 and 17 and left and right cover side extensions 18 and 19 in the opening 15 into which the pad 12 is fitted, and the front cover end extension 16 is sewn. A plurality of short male components 34, 35, 34, 35, 34 of the fastener 33, and a long female component 36 of the fastener 33 at the subsequent cover end extension 17, and the head restraint at the fastener 33. The front and rear cover end extensions 16, 17 are connected to each other by the fastener 33 while being provided with the plurality of wrinkles 32, 32, 32, 32 on the front surface 31 of the front cover 31. Side extension 18,1 Each equipped with a hook 23 and 23 can stop the cover-side extensions 18, 19 to the stay 14, 14 in the hook 23, 23.

As the fastener 33, a plate-shaped resin chuck is used. The chuck 33 is comprised of the plurality of short male components 34, 35, 34, 35, 34 and the elongated female component 36. The plurality of short male components 34, 35, 34, 3
5, 34 are engaged with the female component 36 in a butt-aligned state, and wrinkles 32, 32, 32, 32 are applied to the trim cover 13, so that the male components 34, 35, 34, 35, 34 are provided. Is the wrinkle 3
The length is determined according to the number of 2, 32, 32, 32.

The chuck 33 may have male and female components 34, 35, 34, 35, 34 and 36 of opposite length dimensions. Of course, the shortened female components are sewn to the previous cover end extension 16 and the elongated male components are sewn to the subsequent cover end extension 17, respectively.
