Description

  The present invention relates to a vehicle seat provided with a small case (small case) such as a cup holder on a seat cushion seat surface.

2. Description of the Related Art A vehicular seat is known in which an accessory case (accessory case) such as a cup holder is provided on a seat cushion (upper surface) of a seat cushion so that accessories such as a drink, gum, pen, and tissue can be stored.
Conventionally, a recess is formed in the seat pad at the front end corner of the seat cushion and the like, and a cup holder made of resin or the like is embedded in the recess to store an accessory. In addition, there is also a known configuration in which a bag-like pocket made of cloth is placed in the recess of the seat pad to make a small case, but with this configuration, it is difficult to stably store drinks, etc. A configuration in which a cup holder (accessory case) is embedded is widely adopted.

  For example, in Japanese Patent Laid-Open No. 2006-061536, a seat pad is formed to be harder than other portions at the periphery of a recess, and a trim cover is provided between a flange (outer flange) of a cup holder and a hard portion of the seat pad. The cup holder bottom is pinned to the seat frame on the lower surface of the seat cushion, and the cup holder is embedded and arranged in the recess of the seat pad at the front end corner of the seat cushion.

JP 2006-061536 A

Since the cup holder is generally formed from a relatively hard resin such as PP (polypropylene), the cup holder is embedded in the recess of the seat pad to form a small case (small case). Drinks can be stored stably. However, the seat pad is molded from a foam molding material such as urethane foam in order to ensure the necessary cushioning properties, and because there is a big difference in its hardness from the accessory case (cup holder) made of hard resin, The feeling of foreign objects in the case when sitting is inevitable.
In addition, the end of the trim cover is sandwiched between a flange of an accessory case made of a hard resin and a seat pad made of a foam molding material. When the seat cushion seat surface is bent, the trim cover is trimmed at the opening of the accessory case. A gap is easily generated between the terminal of the cover.

  In Patent Document 1, the seat pad is formed to be harder than the other part at the periphery of the recess, and the occurrence of a gap between the trim cover terminals when the seat cushion seat surface is bent is prevented. .

  However, in order to mold the seat pad harder than the other parts at the periphery of the recess, it is necessary to inject and mold two different foam molding materials melted at high temperatures separately into the mold at high pressure, The molding process becomes complicated and the cost increases.

  Also, the bottom of the accessory case is pinned to the seat frame on the underside of the seat cushion to generate a downward pressing force on the flange of the accessory case, and under this pressing force, the end of the trim cover is pressed against the hard part of the seat pad. The trim cover terminal is not fixed by clamping. Even if the seat pad is molded harder than the other parts at the periphery of the recess, if a large compressive force is applied to the seat pad around the recess, compression and deformation of the hard part of the seat pad cannot be avoided, and the trim cover There is a risk that the terminal will be loosened.

  For example, if the end of the trim cover is clamped under a large frictional resistance by providing irregularities on the lower surface of the accessory case flange, loosening of the clamp can be prevented. However, the shape of the small mold is complicated and the cost is increased. Moreover, even if the flange lower surface is provided with unevenness, it is difficult to completely prevent the loosening of clamping.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle seat having an accessory case that can reliably prevent the occurrence of a gap when seated and does not give a feeling of foreign matter.

  According to the first aspect of the present invention, in the recess formed on the upper surface of the seat pad of the seat cushion, the storage portion formed in a shape corresponding to the recess is embedded, and the storage portion is provided on the seat cushion seat surface. The storage portion is provided with a flange that is open at the upper end, has a flange at the periphery of the upper end opening, and is formed from a soft material that can be sewn with a trim cover that covers the seat pad, and the flange that covers the seat pad. The cover is stitched to the top of the seat pad.

In the present invention according to claim 1, since the accessory case is molded from a soft material, the flange can be sewn to the end of the trim cover, and is sewn and integrated with the trim cover. Even if the seating surface of the seat cushion is bent, there is no room for a gap between the seat and the end of the trim cover, and the generation of the gap is surely prevented.
The accessory case is formed from a soft material that can be stitched, and the difference in hardness from the seat pad is small. Therefore, even when seated, the presence of the accessory case is not felt.

1 is a schematic perspective view of a vehicle seat with an accessory case according to an embodiment of the present invention. FIG. 2 shows a partial cross-sectional view along line AA in FIG. 1.

  A recess is formed in the upper surface of the seat pad of the seat cushion. Then, a storage portion formed in a shape corresponding to the recess is embedded to provide a storage portion on the seating surface of the seat cushion, the storage portion is open at the upper end, and has a flange at the periphery of the upper end opening, A trim cover that covers the seat pad and a soft material that can be stitched are formed. The flange of the storage portion is sewn on the end of the trim cover that covers the seat pad on the upper surface of the seat pad.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic perspective view of a vehicular seat with an accessory case according to an embodiment of the present invention, and FIG. 2 is a partial cross-sectional view taken along line AA in FIG.

  As shown in FIG. 1, the vehicle seat 10 includes a seat cushion 12 and a seat back 14 provided at the rear end of the seat cushion, and an armrest 14 a is provided on a side surface of the seat back around a pin 14 a 1. A headrest 14h is provided on the upper surface of the seat back so as to be able to swing up and down. The basic structure of the seat cushion 12 and the seat back 14 is well known, and a seat pad made of a foam molding material such as urethane foam is placed on a seat frame as a skeleton, and the seat pad is covered with a breathable trim cover. A seat back is formed.

  As can be seen from FIG. 2 showing a cross section taken along line AA in FIG. 1, a recess 12P1 is formed, for example, at the front end of the seat pad 12P of the seat cushion. A small case (small case, cup holder) 16 such as a cup holder is provided on (upper surface) 12U.

  The recess 12P1 is formed in a case shape capable of storing small items such as drinks, gums, pens, tissues, etc., for example, a transverse cross section is rectangular, circular, non-circular (for example, oval), and a vertical cross section is rectangular. . The accessory case 16 is opened from the upper end, has a flange (outer flange) 16a at the periphery of the upper end opening, and is molded from a soft material into a shape corresponding to the recess 12P1. As the soft material, for example, an elastomer, Examples of the material that can be sewn such as a soft resin and a molded nonwoven fabric can be given.

  As shown in FIG. 2, the accessory flange 16a is bent downward (in the direction of the bottom of the accessory case) at its end and corresponds to the bent end 16a ', that is, along the bent end. The end of the trim cover 12c is folded downward. The bent end 16a 'of the flange and the folded back 12c' of the trim cover terminal are stitched together. Reference numeral 18 indicates a stitched portion.

  Since the bent end 16a 'of the flange is sewn to the fold 12c' of the trim cover terminal, and the accessory case 16 is integrated with the trim cover 12c, the trim cover terminal 16b can be attached even if the seat cushion seat surface is bent due to the seating. There is no room for a gap between them, and the generation of the gap is reliably prevented.

  Unlike the conventional configuration in which two types of foamed molding materials are fed into a molding die to mold portions having different hardnesses, the bent end 16a 'of the flange and the folded back 12c' of the trim cover terminal are integrated by stitching. It is sufficient, and the configuration is simple and the cost can be reduced.

  The tip of the accessory case flange 16a is bent downward, the end of the trim cover is folded back corresponding to the bent end 16a ', and the bent end is stitched to the turn 12c' of the trim cover terminal. Therefore, even if a tensile force is generated at the end of the trim cover 12, there is a room for deforming the bent end, which can be used as a play to prevent the stitched portion 18 from being broken. In other words, a durable structure capable of dealing with the tensile force can be obtained as compared with the case where the end of the trim cover 12c is directly overlapped and stitched to the flange 16a without the bent end 16a '.

  The accessory case 16 is formed from a soft material that can be stitched and has a small difference in hardness from the seat pad 12P made of foamed molding material such as urethane foam, so that the presence of the accessory case can be felt even when seated. There is no.

  Since the accessory case 16 is molded from a soft material and embedded in the recess 12P1 of the seat pad, and the flange 16a of the upper end opening is sewn to the end of the trim cover 12c, the bottom of the accessory case is used as a seat frame or the like. Even if it is not pinned, its outer shape is maintained without collapse and can stably store small items such as drinks, gums, pens, and tissues.

  Just by embedding the accessory case 16 in the recess of the seat pad and sewing the flange 16a to the end of the trim cover 12c, the accessory case is provided on the seat cushion seat surface, and the accessory case is pinned to the seat frame or the like. Therefore, the workability is improved and the cost can be reduced from this point.

  As described above, according to the present invention, since the accessory case is integrated with the trim cover by stitching, generation of a gap between the terminal of the trim cover is prevented. Moreover, since it consists of a soft material, even if an accessory case exists in the seat cushion seat surface 12U, it does not feel a foreign material feeling.

  The above-described embodiments are for explaining the present invention, and are not intended to limit the present invention. All modifications, alterations, etc. within the technical scope of the present invention are included in the present invention. Needless to say.

  Examples of soft materials for the accessory case 16 include elastomers, soft resins, and molded nonwoven fabrics, but the present invention is not limited to this, and any material that can be sewn to the trim cover, does not feel foreign matter, and can stably store accessories. That's fine.

  In the embodiment, the accessory case 16 is provided at the front end of the seat cushion seat surface 12U. However, the position of the accessory case is not limited to this, and may be provided at the left and right ends of the seat cushion seat surface.

  Furthermore, in the embodiment, the case where the accessory case 16 is provided on the seat cushion seat surface 12U has been described. However, the position where the accessory case is provided is not limited to the seat cushion seat surface, and other positions, for example, the armrest 14a. It may be provided on the upper surface.

Although the present invention is suitable for front seats such as driver seats and assistant seats, it can also be applied to seats such as second seats and third seats.
Furthermore, the present invention is usually applied to automobile seats, but the present invention can also be applied to vehicle seats other than automobiles, for example, trains, airplanes, and the like.
