Description

  The present invention relates to a vehicle seat in which a pocket for an accessory case is provided on a side surface of a seat back.

2. Description of the Related Art A vehicular seat is known in which a pocket for a small case is provided on a side surface of a seat back so that small items such as gum, sunglasses, a pen, and a tissue can be stored.
Conventionally, a pocket for an accessory case is formed on the side surface of the seat back by attaching the resin case to the side surface of the seat back or stitching the fabric to the trim cover on the side surface of the seat back.

For example, in Japanese Utility Model Laid-Open No. 06-053303, a pair of opposing locking pieces are extended laterally from a resin case having a substantially semicircular cross section made of a synthetic resin, and attached to a frame behind a hole provided on the side surface of the seat back. A configuration is described in which a pocket for a small case is attached to a side surface of a seat back by locking a locking claw at the tip of the locking piece.
In Japanese Utility Model Laid-Open No. 06-065099, a substantially rectangular pocket fabric is formed from the same fabric as the trim cover, and the peripheral edge of the fabric is sewn to the trim cover except for the opening at the upper end to provide a pocket for the accessory case. The structure formed on the side surface of the seat pad is described.

  Furthermore, a configuration is also known in which an accessory pocket is provided on the back surface instead of the side of the seat back. For example, Japanese Patent Application Laid-Open No. 2005-168788 has a space on the back surface of the seat back to provide an accessory pocket. The configuration is described.

In the configuration of Patent Document 2 in which the pocket is sewn into the trim cover to make a pocket for small items, the pocket (fabric) does not protrude before putting small items, but it protrudes from the side of the seat back when small items are inserted. It becomes. Such protrusion of the pocket from the side surface of the seat back is not only accompanied by a decrease in appearance quality, but in the seat with the armrest, the armrest is flipped up, and in the storage seat, the seat is stored in the storage space. Each may interfere. For this reason, it is unavoidable that pockets of the type protruding to the side surface of the seat back are inferior in adaptability and versatility to vehicle seats, particularly automobile seats.

On the other hand, in the configuration of Patent Document 3, since a space is provided on the back of the seat back to form a pocket, there is no protrusion of the pocket to the side of the seat back, and the versatility and adaptability in addition to the improvement in appearance quality are improved.

  As shown on the left side surface of the seat back of the right seat 10R in FIG. 1, the second recess 16-2 serving as an accessory case space is opened without being covered with a trim cover. The seat pad is fitted into the second recess 16-2.

3A is a perspective view of the frame, and FIG. 3B is a cross-sectional view taken along line BB in FIG. 3A. As shown in FIGS. 3A and 3B, for example, the frame 18 is a molded product, and a flange with a folded piece 18b is formed from a soft material into a substantially rectangular shape corresponding to the shape of the second recess 16-2. Formed around the periphery, the molded product (frame body) is fitted into the second recess, and the folded piece of the flange is sewn to the periphery of the opening of the trim cover to form a pocket for small items on the side of the seat back. The Examples of the soft material used as the material of the molded product (frame body) 18 include moldable and stitchable materials such as elastomers, soft resins, and molded nonwoven fabrics.
Usually, the folded-back piece 18b of the flange is connected to the trim cover by sewing, but is not limited to sewing, and the flange may be connected to the trim cover by thermocompression bonding or an adhesive. Further, the frame 18 may be fixed by screwing the seat back frame or the like.

For example, as shown in FIG. 1, the molded product (frame body) 18 is formed in a substantially rectangular shape having an opening 18a for small articles in the front upper part (front upper part), and the second recess 16-2 of the seat pad. If it arrange | positions to, the accessory thrown in from upper opening is accommodated in the front lower part of closed space, and is accommodated, without protruding from the recess (pocket) 16-2. In addition, small objects in the recesses (pockets) are concealed by the wall surface at the front lower part that defines the closed space, and small objects are stored in the concealed state.
Except for the upper opening 18a, the front surface of the molded product 18 may be covered with a trim cover to make the presence of pockets inconspicuous.

  As described above, according to the present invention, since the accessory case space as a recess is provided on the inner side surface 14I of the seat back, the accessory case does not protrude outward from the side surface of the seat back. It can be stored without protruding from the pocket, and side storage without protruding becomes possible. In addition, since there are no protrusions on the side surface of the seat back, not only a clean appearance design can be obtained, but also an accessory case that does not adversely affect the lifting of the armrest or the storage of the seat can be easily secured.

  A pocket for small items does not protrude from the side surface of the seat back, and a second recess 16-2 serving as a small space is provided on the inner side surface of the seat back that is symmetrical to the airbag storage space. Since it is only provided, the accessory case can be formed without reducing the elasticity of the seat back seating surface or giving the seated person an uncomfortable feeling.
