[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a headrest mounted on the upper end portion of a seat back of a vehicle seat, and a headrest cover structure for fastening first and second terminal portions of a cover skin covering the headrest body. It is about.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 5 and 6, a cover skin 11 'for covering a headrest main body 4' is sewn into a bag shape having an opening at the center of the lower end thereof. ´. Of the first and second terminal portions 12 'and 15' forming the bag opening of the cover skin 11 ', the first terminal portion 12'
, A holding plate 21 ′ is fixed, and a second terminal portion 15 ′ is attached to a terminal plate 18 ′ corresponding to the holding plate 21 ′.
Is fixed.

As shown in FIG. 6, the holding plate 21 '
Has a locking hook which is folded back in parallel toward the side to which the first terminal portion 12 'is fixed and has an insertion groove 23'
22 'is formed. Then, by inserting the second terminal portion 15 'together with the terminal plate 18' from the insertion opening of the insertion groove 23 ', the second terminal portion 15' is fixed to the holding plate 21 '. I have.

[0004]

By the way, in the above-mentioned conventional device, the terminal plate 18 'easily comes off from the insertion opening of the insertion groove 23' of the holding plate 21 ', and furthermore, the position in the lateral direction is increased. It is easy to slip. For this reason, when an external force is applied to the cover skin 11 ′, or when the cover skin 11 ′ becomes slack due to a difference in the coefficient of thermal expansion between the headrest body 4 ′ and the cover skin 11 ′, the insertion groove of the holding plate 21 ′. There was a case where the terminal plate 18 'slipped out of the insertion opening of 23' and came off, or moved laterally and came off.

An object of the present invention is to provide a headrest cover structure capable of positively preventing the terminal plate from coming off the insertion groove of the holding plate in view of the above-mentioned conventional problems.

[0006]

In order to achieve the above-mentioned object, the present invention is directed to a first and second terminal portions of a cover skin covering a headrest main body, the first terminal portion having a holding plate. While being fixed, a terminal plate is fixed to the second terminal portion, and a locking hook having an insertion groove into which the second terminal portion of the cover skin is inserted together with the terminal plate is formed on the holding plate. A headrest cover structure, wherein the locking hook of the holding plate always closes the insertion slot of the insertion groove, and is elastically deformable in a direction of expanding the insertion groove when the terminal plate is inserted. The terminal plate is provided at both side edges thereof with stopper pieces for engaging with both sides of the holding plate to prevent lateral displacement.

[0007]

In the headrest cover structure configured as described above, the insertion groove is expanded while the locking hook of the holding plate fixed to the first terminal portion is elastically deformed. The second terminal part of the cover skin is inserted together with the terminal plate from the insertion port. When the second terminal portion of the cover skin is inserted together with the terminal plate to the required position of the insertion groove, the locking hook is returned to the original state by the elastic force based on the elastic deformation, and the insertion hole of the insertion groove is inserted. Is closed and the stopper pieces of the terminal plate are engaged with both sides of the holding plate, whereby the second terminal portion of the cover skin is fixed to the holding plate. In the state where the second end portion of the cover skin is fixed to the insertion groove of the holding plate in this way, the insertion hole of the insertion groove is closed by the locking hook, so that the terminal plate is pulled out from the insertion hole. You are prevented from leaving. Further, the lateral displacement of the terminal plate is also prevented by the stoppers of the terminal plate engaging with both sides of the holding plate.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 3 and 4, a headrest 3 that is attached to the upper surface of the seat back 2 of the vehicle seat 1 so as to be adjustable in height is mainly composed of a headrest main body 4 and a cover skin 11 that covers the headrest main body 4. You. The headrest main body 4 includes a pad 5 having cushioning properties such as urethane foam, a core metal (not shown) inserted into the pad 5, and a predetermined lower surface fixed to the lower surface of the core metal and suspended from the lower surface of the headrest main body 4. And a stay 6 protruding in length.

A cover skin 11 for covering the headrest body 4
Is sewn in a bag shape with a central portion of the lower end opened, and is covered with the headrest body 4. Of the first and second terminal portions 12 and 15 forming the bag opening of the cover skin 11, the first terminal portion 12 is fixedly attached to the holding plate 21 divided into three portions at the center and both left and right sides, respectively. The terminal plate 18 divided into three portions corresponding to the holding plates 21 is fixed to the two terminal portions 15.

As shown in FIGS. 1 and 2, the holding plate 21 is formed of a synthetic resin such as polypropylene, and the first end portion 12 of the cover skin 11 is sewn to one side of one side by sewing. Wearing 13 is done. At one end of the holding plate 21, a locking hook 22 is formed which is folded toward the side where the first terminal portion 12 is to be sewn. Is formed. The distal end of the locking hook 22 extends to a position where the insertion slot of the insertion groove 23 is substantially closed, and when the terminal plate 21 is inserted, the locking hook 22 is elastic in a direction to expand the insertion groove 23. It is formed integrally with the holding plate 21 so as to be deformable. Further, a stopper surface 24 is formed on the insertion opening side of the insertion groove 23 so as to abut on the end face of the terminal plate 18 to prevent the terminal plate 18 from moving toward the insertion side.

A terminal plate 18 sewn 16 to the second terminal portion 15 of the cover skin 11 by sewing is formed into a flat plate made of a synthetic resin such as polypropylene and having a size to be inserted into the insertion groove 23. Is formed. On both side edges of the terminal plate 18, slip stoppers 19 for engaging with both sides of the holding plate 21 to prevent lateral displacement are formed.

This embodiment is configured as described above.
Therefore, after the holding plate 21 is sewn 13 to the first end portion 12 of the cover skin 11 and the end plate 18 is sewn 16 to the second end portion 15 of the cover skin 11, the cover skin 11 is attached to the headrest body 4. Is covered. Then, with the insertion groove 23 expanded while the locking hook 22 of the holding plate 21 is elastically deformed, the second terminal portion 15 of the cover skin 11 is moved from the insertion port of the insertion groove 23 to the terminal plate 18. Is inserted with.

When the second end portion 15 of the cover skin 11 is inserted together with the end plate 18 to a required position of the insertion groove 23,
The locking hook 22 is returned to the original state by the elastic force based on the elastic deformation, and the insertion opening of the insertion groove 23 is closed, while the slip stopper 19 of the terminal plate 18 is engaged with both sides of the holding plate 21. The second end of the cover skin 11
15 is fixed to the holding plate 21.

[0014]

[Effect of the invention] As described above, according to the invention,
Inserting the terminal plate of the second terminal portion of the cover skin to a required position of the insertion groove while elastically deforming the locking hook of the holding plate fixed to the first terminal portion of the cover skin, As a result, the insertion opening of the insertion groove is closed, and the stopper pieces of the terminal plate are engaged with both sides of the holding plate. As a result, it is possible to solve the problem that the terminal plate is pulled out from the insertion slot of the insertion groove of the holding plate and comes off, or moves laterally and comes off.
