Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to head restraints used in vehicle seats.

BACKGROUND ART Generally, in a head restraint, in order to give a soft feeling, a structure in which a soft slab is fitted and adhered in a recess formed in a surface of a head restraint pad at a predetermined position is used. However, since the slab is retrofitted in that way, the edges of the slab are ribbed onto the surface of the pad,
As a result, the surface of the skin was stepped, resulting in a poor appearance.

In addition, Japanese Utility Model Laid-Open No. 59-182251 discloses a pad for a vehicle seat or the like in which a wadding is fitted into a recess opened in the pad surface and bonded. There, the wadding is crushed because the wadding is formed smaller than the opening of the dent and a gap is formed between the dent and the wadding in the fitted state, which is opened to the pad surface. Then, at the gap, the epidermis is folded, and the repetition of it causes a bad appearance.

Problem to be Solved by the Invention The problem to be solved by the invention is to prevent a gap between a pad and a soft slab fitted in the recess in the recess formed in the surface of the head restraint pad from being opened in the surface of the pad. It prevents the edges of the slab from protruding in a rib shape on the surface of the pad, and prevents the skin from being stepped by the protrusion of the slab, and when the slab is crushed, To provide a head restraint used for a vehicle seat that avoids the skin from being bent at the boundary between the pad and the slab, and prevents the skin from sagging due to the repetition thereof. is there.

DESCRIPTION OF SPECIFIC EXAMPLES Hereinafter, a head restraint used in a vehicle seat of the present invention will be described based on the specified and illustrated specific examples. FIGS.
Shows a specific example 10 of the head restraint used in the vehicle seat of this invention as applied to the seat,
In this head restraint 10, a head restraint pad 11 is molded with a recess 16 that is opened in the surface at a predetermined position, and a slab 12 is formed on the back surface by cutting off an edge. And a flank 17 to be molded.

In particular, the slab 12 has its outer dimensions fitted and fitted in its recess 16 as shown in FIG.
Molded into a plate shape from a resin softer than 11.

Further, in this head restraint 10, 13 is an insert bore, 14 is a stay, and 15 is an epidermis.

Therefore, first, the adhesive is applied to the bottom surface of the recess 16, and then the slab 12 is fitted into the recess 16.

When the slab 12 is fitted into the recess 16, the clearance surface 17 forms a space 18 at the bottom of the recess 16 as shown in FIG. , The slab 12 is fitted, that is, the gap between the pad 11 and the slab 12 that is opened to the surface of the pad 11 is omitted, and the pad 11 and the slab 12 have their surfaces on each other. It fits in the recess 16 in the aligned state.

Further, since the slab 12 is thus housed in the recess 16 without adhering the peripheral edge of the back surface to the bottom surface of the recess 16 and forms the space 18 at the bottom of the pad 11, the edge of the slab 12 is formed. Is prevented from protruding in a rib shape on the surface of the pad 11, and the outer skin is prevented from being stepped by the protrusion of the edge of the slab 12, and
When the slab 12 is crushed by the driver's head from above the epidermis, it is avoided that the epidermis is bent at the boundary between the pad 11 and the slab 12, and
The settling of the epidermis due to the repetition of it is prevented in advance. That is, the rib-shaped protrusion of the edge of the slab 12 is absorbed in the space 18, and when the slab 12 is crushed, the skin at the boundary between the pad 11 and the slab 12 is the surface of the slab 12. It is supported by the peripheral part and can be bent smoothly.

In the slab 12 described above, the flank 17 is an inclined surface, but the flank 17 may be a stepped surface.

As will be apparent from the specific embodiments of this invention as described above with reference to the drawings, those of ordinary skill in the art to which this invention belongs,
The subject matter of this invention derives from the nature and substance of its invention and is readily embodied in other embodiments which are objectively accepted to bring them into existence. Of course, the contents of this device are commensurate with the subject of the device and are essential to the establishment of the device.

Benefits of the Invention As can be understood from the above, the head restraint used in the vehicle seat of the present invention has a head restraint pad having a recess opened at a predetermined position on the front surface and a head restraint pad on the back surface. The head restraint used in the vehicle seat of the present invention has a flank formed by cutting off the edge, and includes a slab fitted and glued in the recess. This creates a space at the bottom of the depression, which makes the slab fit very well and avoids opening a gap between the pad and the slab on the surface of the pad, It fits into the surface of the pad in the recess, and the protrusion of the edge of the slab is absorbed in the space so that the edge of the slab becomes the surface of the pad. Of the slab is prevented from being stepped by the protrusion of the edge of the slab, and further, when the slab is crushed, the skin is separated at the boundary between the pad and the slab. Is supported by the peripheral part of the surface of the slab and smoothly bent,
The skin is prevented from being bent, and sagging of the skin due to its repetition is prevented, so that it looks good in long-term use, and as a result, it is very useful and practical for vehicle seats. is there.
