Description

[Detailed Description of the Invention] "Field of Industrial Application" The present invention is a headrest device in which a stay extending downward from the headrest body is swingably pivoted to the seat back in order to adjust the front and back position of the headrest body. Regarding.

``Prior Art'' Conventional headrest devices include those shown in FIGS. 4 and 5, for example.

That is, the lower end of the stay 2 is pivotably supported on the seat back 1, a long hole 4 for passing the stay 2 upward is bored in the skin member 3 of the seat back 1, and a head rest is attached to the upper end of the stay 2. Main body 5
is installed. When the headrest main body 5 is moved in the front-rear direction, the intermediate portion of the stay 2 reciprocates within the elongated insertion hole 4.

``Problem to be solved by the invention'' However, in such a conventional head restraint device, the peripheral edge of the elongated hole 4 for insertion of the skin member 3 is weak, wrinkles occur, and the appearance is not good.
Additionally, there was a problem in that it would break if used for a long period of time, resulting in poor durability.

The present invention was developed by focusing on these conventional problems.The peripheral edge of the elongated hole for insertion is reinforced, and the peripheral edge is maintained in a predetermined shape to provide a good appearance and durability. The purpose is to provide an excellent headrest device.

``Means for Solving the Problems'' The gist of the present invention to achieve the above object is as follows: In order to adjust the front and back position of the headrest body, a stay extending downward from the headrest body can be swung against the seat back. In a head restraint device that is pivotably supported, a long hole for inserting the stay is bored in the skin member of the seat back, and a resin-made hole is formed on the back side of the peripheral edge of the long hole for inserting the stay, along the shape of the back surface. The present invention relates to a headrest device characterized by a iron having a reinforcing plate member attached thereto.

``Function'' When you swing the stay or lean your back against the seat bag in order to adjust the front-back position of the headrest body, the stay relatively rubs against the periphery of the elongated hole for inserting the stay, but the reinforcing plate member Therefore, the periphery of the elongated hole for inserting the stay is not easily deformed, and even if deformed, it is restored by the elastic force of the reinforcing plate member. Further, even when the stay repeatedly rubs the periphery of the elongated hole for the stay insertion, the reinforcing plate member reinforces the periphery of the elongated hole for the stay insertion, so that it is hard to wear and will not break.

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

1 to 3 show an embodiment of the present invention.

As shown in FIG. 3, the seat bag 10 is constructed by covering a back frame 11 and the like with a skin member 20. A pivot bracket 12 is attached to the back frame 11.
A pivot 13 is swingably supported via the pivot 1
A holder 14 is fixed to the stay 30 so that the pair of legs 31 of the stay 30 can be inserted into the stay 30 in the vertical direction. The upper end of the stay 30 has a head rest main body 4.
0 is fixed.

As shown in FIGS. 1 and 2, the skin member 2
0 consists of a skin 21 and a wading 22, and each of the skin members 20 has elongated holes 23 for inserting the stay through which the pair of legs 31 of the stay 30, which is held by the holder 14 and extends upward, is passed. Similarly, the butt member 24 is provided with a long groove 25 for inserting the stay.

A reinforcing plate member 50 made of resin is arranged along the back shape of the upper part of the skin member 20, and the reinforcing plate member 50
A long groove 51 is bored in the hole 51 in correspondence with the long hole 23 for inserting each stay. The reinforcing plate member 50 is sewn to the peripheral edge portion 26 of each elongated hole 23 for insertion of the stay. The reinforcing plate member 50 is made of a low foam material having a predetermined restoring force.

The reinforcing plate member 50 may be attached, for example, by gluing instead of being sewn. Furthermore, instead of simultaneously reinforcing each of the elongated holes 23 for insertion of the stays with a single reinforcing plate member 50, the elongated holes 23 may be reinforced with separate reinforcing plate members. Furthermore, as shown in FIG. 1, a reinforcing plate member 55 having such a shape may be attached to the back side of a portion of the skin member 20 where an inverse shape is required.

A thin plate-like elastic member 27 is integrally sewn to the peripheral edge 52 of the long groove 5 of the reinforcing plate member 50 with the skin member 20 and the like so as to cover the long hole 23 for inserting the stay from the outside. A slit is cut in the center of the thin plate-shaped elastic member 27, so that the elastic member 27 is bent and separated into two tongue pieces 28 through which the legs 31 of the stay 30 can be inserted.

Next, the action will be explained.

When the headrest main body 40 is in a predetermined front-rear position, the legs 31 of the stay 30 are in a predetermined position in the elongated hole 23 for inserting the stay, and in the region where the legs 31 are located, the tongue of the thin elastic member 27 is The tongue pieces 28 are bent and abut against the leg portions 31 from both sides, and the tip portions of the tongue pieces 28 are in a flat state and abut against each other in areas other than where the leg portions 31 are located. That is,
Due to the thin plate-like elastic member 27, the back frame 11 and the like cannot be seen through the long hole 23 for inserting the stay, so that the appearance is not impaired.

When the back is rested on the seat bag 10, the load applied to the seat back is also applied to the peripheral edge 26 of the elongated hole 23 for inserting the stay and the peripheral edge 52 of the elongated groove 51 of the reinforcing plate member 50. Since the reinforcing plate member 50 can sufficiently withstand the load, the peripheral edge 26 of the elongated hole 23 for inserting the stay is not easily deformed, and even if it is deformed, it is restored by the elastic force of the reinforcing plate member 50. Thereby, even after repeated use, the peripheral edge 26 of the elongated hole 23 for inserting the stay does not deform and maintains its initial predetermined shape.

When the user rests his or her back on the seat bag 10, the peripheral edge 26 of the elongated hole 23 for inserting the stay is deformed.
At this time, not only the peripheral edge 26 of the long hole 23 for inserting the stay, but also the peripheral edge 52 of the long groove 51 of the reinforcing plate member 50 and the tongue piece 28 of the thin elastic member 27 come into contact with the leg 31 of the stay 30. .

In this abutting state, vibrations during traveling are transmitted to the seat back 10, and the legs 31 of the stay 30 repeatedly rub against the peripheral edge 26 of the elongated hole 23 for inserting the stay. In such cases,
The peripheral edge 26 of the long hole 23 for inserting the stay does not get rubbed intensively, and the peripheral edge 26 of the long hole 23 for inserting the stay is reinforced by the reinforcing plate member 50, making it difficult to wear and prevent cracks. It does not get wet and has improved durability.

In addition, although the reinforcing plate member was fixed to the skin member in the above embodiment, it goes without saying that it may be attached to the pad member.

"Effect of the invention" According to the head restraint device according to the invention, a reinforcing plate member made of resin is attached to the periphery of the elongated hole for inserting the stay along the shape of the periphery, so that the periphery is reinforced. , looks good without wrinkles, maintains its shape even after long-term use,
Durability can be improved.
