As shown in FIG. 1, the seat belt buckle storage structure of the present embodiment has a recess 3 </ b> A that is formed on the seating surface of the seat cushion 3 of the vehicle seat 1 and can store a buckle 5 of a seat belt device (not shown). Concerning structure. Specifically, an inside-visible preventing structure for covering the opening surface on the back side of the recess 3A so that the support member (support plate 5A) of the buckle 5 exposed in the recess 3A is not visible from the outside in the recess 3A. Is provided. Here, the support plate 5A corresponds to the “support member” of the present invention. The inside-view preventing structure is configured by a planar cover member 20 disposed in a state where the surface is directed obliquely upward and diagonally across both side surfaces 3B in the recess 3A. The configuration of the cover member 20 will be described in detail later.

  Here, the vehicle seat 1 is a 4: 6 divided narrow side seat among seat seats for three seats long in the seat width direction arranged in the last row of the vehicle. It is configured. The vehicle seat 1 includes a seat back 2 that serves as a backrest for a seated occupant, a seat cushion 3 that serves as a seating portion, and a headrest 4 that serves as a support for the head. Both the seat back 2 and the headrest 4 are configured such that a cushion pad is placed on an internal skeleton structure (not shown) and the entire surface is covered with a planar skin material. The cushion pad is made of a foamed molded body of urethane resin, and the skin material is made of a flexible cloth material.

  The seat cushion 3 has a long shape with a seating surface for the above three seats, and, like the seat back 2 described above, a cushion pad 30 is put on an internal skeletal structure (not shown). The entire surface is covered with a planar skin material 10. The cushion pad 30 is composed of a urethane resin foam molded body, and the skin material 10 is composed of a flexible planar cloth material.

  A buckle 5 for use by an occupant seated on the same side is exposed from the lower rear side of the seat cushion 3 on the seating surface of the divided narrow region of the seat cushion 3. It is provided as a state. A rectangular recess 3A that can accommodate the buckle 5 is formed in an area on the seating surface of the seat cushion 3 in which the buckle 5 is disposed.

  Here, the buckle 5 is integrated with a frame portion of the seat cushion 3 (not shown) by allowing a metal support plate 5A coupled to the base portion of the buckle 5 to pass through the recess 3A to the lower back side of the seat cushion 3. The bolt is fastened and fixed. The buckle 5 can be turned up and down with the bolt fastening portion (not shown) as a starting point, and by this turning, the buckle 5 can be pulled out to the upper side of the concave portion 3A or stored in the concave portion 3A. It can be done.

  As shown in FIG. 2, the recess 3 </ b> A is formed such that a part of the rear edge of the cushion pad 30 that forms the outer shape of the seat cushion 3 is recessed so as to penetrate in the seat vertical direction. The recessed inner peripheral surface of the recess 3 </ b> A is covered with a plurality of covering pieces 11 continuously stitched to the skin material 10 covered on the seating surface of the seat cushion 3. Here, the skin material 10 is put on the seat cushion 3 from the upper side, and the front, rear, left and right peripheral portions thereof are pulled into the bottom surface side of the seat cushion 3, and the hook is not shown in the drawing structure. It is in a state of being hooked and fixed on a wire laid on the skeleton of the cushion 3.

  Each covering piece 11 is made of a flexible surface-like cloth material, and is formed so as to cover each side surface 3B of the concave portion 3A. The edges are integrally stitched and joined to the peripheral edge facing the recess 3A of the skin material 10 (sewed portion 11A). The lower edge portion of each covering piece 11 is pulled into the bottom surface side of the seat cushion 3 in the same manner as the peripheral edge portion of the skin material 10 and is laid on the skeleton portion of the seat cushion 3 by a hook engagement structure (not shown). It is in a state of being fixed by being hooked on the wire.

  As shown in FIGS. 2 to 3, the cover member 20 made of a carpet material cut into a rectangular shape is folded and protruded into the recess 3 </ b> A on the side surface 3 </ b> B inside the sheet of the recess 3 </ b> A. It is provided as a held state. Here, the cover member 20 is made of a carpet material that is thicker than the skin material 10, and in the free state, the cover member 20 is a flexible member having rigidity capable of maintaining a state in which the surface is straightened against its own weight. It is configured. The cover member 20 is provided in a state where the cover member 20 is held in a shape bent in the recess 3A with respect to the side surface 3B of the recess 3A by the following procedure.

  That is, as shown in FIG. 4, the cover member 20 is formed by first folding a rectangular carpet material into a double folded state, and then fixing each surface portion (fixed surface portion 21) on both edge sides by the folding. Then, the side surface 3B of the recess 3A is shaped so as to face the side surface 3B of the recess 3A so as to face downward and the first part surface 21B close to this edge is sewn along the edge. To be connected to each other (first stitching portion 21A). In this state, the cover member 20 is in a state in which the cover member 20 maintains an upright state in which the surface extends straight and obliquely upward along the side surface 3B of the recess 3A due to its own rigidity matched to the double. ing. Here, the first stitching portion 21A corresponds to the “first stitching portion” of the present invention.

  Next, as shown in FIG. 5, the front surface portion (covering surface portion 22) stitched by the first stitching portion 21A of the cover member 20 is aligned with the fixed surface portion 21 so as to fall into the recess 3A. The second portion surface 22B that is bent in the direction (oblique direction) and is close to the base side of the bent cover surface portion 22 is positioned on the side where the bending is advanced (the fixed surface portion 21 described above in the present invention). The second surface of the second portion 22A). ). Specifically, the stitching of the second stitching portion 22A is performed in a rear half region of the cover surface portion 22 in the surface width direction. As a result, the cover surface portion 22 of the cover member 20 is drawn to the fixed surface portion 21 that is stitched at the rear half region portion (second portion surface 22B) stitched by the second stitching portion 22A. As shown, the urging force is applied to the direction in which the bending proceeds. Here, the second stitching portion 22A corresponds to the “second stitching portion” of the present invention.

  However, the cover surface portion 22 of the cover member 20 is not subjected to the pulling force as described above in the remaining front half region portion that is stitched by the second stitching portion 22A, and the direction in which the folding is returned due to its rigidity. It is supposed to be in a state of exerting an energizing force. Therefore, the cover surface portion 22 of the cover member 20 is always in a state of maintaining a straight standing state in the concave portion 3A in which these acting forces are balanced by both the operations in which the urging forces are exerted in directions opposite to each other. Is retained. Specifically, the cover surface portion 22 of the cover member 20 is held in a state in which the surface is directed straight upward and obliquely forward. As a result, the cover surface portion 22 of the cover member 20 is held in a state where the support plate 5A of the buckle 5 passed through the space portion below the cover member 20 is covered with a wide surface so as not to be seen from the outside. It is in a state.

  Here, as described above, the second stitching portion 22A is set in the area portion of the rear half of the cover surface portion 22 of the cover member 20, so that the upper surface thereof is a sheet as shown in FIG. It is concealed by the shape of the back 2, and the stitched portion is hardly visible from the outside. Thereby, it is set as the state by which the cover surface part 22 of the cover member 20 was arrange | positioned in the state of appearance. Further, since the cover surface portion 22 of the cover member 20 is arranged in a state where the surface is directed straight upward and obliquely forward, the concave portion when the inside of the concave portion 3A is viewed from the occupant seated on the vehicle seat 1 The opening on the back side of 3A is in a state in which it is effectively prevented from being seen as a state where the opening is widely covered by the cover surface portion 22 of the cover member 20. Further, the cover member 20 for preventing the inside from being visible has a function of covering the support plate 5A of the buckle 5 as described above by having a flexible structure supported in a cantilever manner. However, when pulling out the buckle 5 to the upper side of the recess 3A, the buckle 5 is easily bent by being pushed up from the lower side by the support plate 5A, so that the operation of moving the buckle 5 is not hindered.

  Thus, according to the seatbelt buckle storage structure of the present embodiment, it is possible to simply form the anti-invisible structure in the recess 3A by utilizing the rigidity of the cover member 20 itself and the coupling structure by stitching. . Moreover, since each coupling | bonding of the cover member 20 shall be performed by sewing, each coupling | bonding can be performed rationally and simply using the stitching | suture equipment which stitch | sutures the structural pieces of the skin material 10 of the seat cushion 3. FIG. In addition, it is possible to easily form the first stitched portion 21A and the second stitched portion 22A in a line shape in the surface width direction by stitching. In addition, since the second stitching portion 22A (second portion surface 22B) is set at one place in contact with the rear side edge portion of the cover member 20 in the surface width direction, it is compared with that formed by being dispersed in the front-rear direction. The operation of bringing the second part surface 22B close to the fixed surface portion 21 and combining them can be easily performed.

  As mentioned above, although the embodiment of the present invention has been described using one example, the present invention can be implemented in various forms in addition to the above example. For example, as shown in FIG. 6, the fixed surface portion 21 of the cover member 20 includes an upper edge portion of the covering piece 11 that covers the side surface 3B of the recess 3A, a peripheral portion of the skin material 10 that covers the seating surface of the seat cushion 3, The first stitched portion 21A is folded so as to fall into the recess 3A. The first stitched portion 21A is stitched together so as to be sandwiched between the stitched portions (first stitched portion 21A). Then, the second part surface 22B (the rear half region in the surface width direction of the cover surface portion 22) close to the base side of the bent cover surface portion 22 is a recess 3A located on the side where the bending is advanced. The cover member 20 is set in such a manner that it is brought into contact with the side surface 3B and joined to the side surface 3B by sewing together along the edge (second stitching portion 22A). Also good.

  Further, as shown in FIG. 7, the fixed surface portion 21 of the cover member 20 includes an upper edge portion of the covering piece 11 that covers the side surface 3B of the recess 3A, a peripheral portion of the skin material 10 that covers the seating surface of the seat cushion 3, The first surface portion (covering surface portion 22) stitched by the first stitching portion 21A is temporarily placed on the skin material 10 so as to be sandwiched between the stitching portions of the first stitching portion 21A. After folding so as to overlap, it is further folded so as to fall into the recess 3 </ b> A, and the second part surface 22 </ b> B (the rear side in the surface width direction of the covering surface portion 22) close to the base side of the folded covering surface portion 22. The fixed surface portion 21 (skin material) is formed in such a manner that the half region) is brought into contact with the fixed surface portion 21 (skin material 10) located on the side where the bending is advanced and is aligned and stitched along the edge. 10) jointly stitched together (second Engagement part), it may be set to cover member 20. The other configurations described in FIGS. 6 and 7 are the same as the configurations shown in the first embodiment, and thus the same reference numerals are given and the description thereof is omitted.

  In addition to the carpet shown in the above embodiment, the material of the cover member is a flexible material that can maintain a straightly extended state against its own weight due to its own rigidity in its free state. Any other material may be used as long as it is made of a planar material. Specific examples include fabrics made of woven fabrics and knitted fabrics, and flexible planar members such as leather and rubber. Further, the cover member does not have to be used by being folded in double folds, and may be used without being folded when sufficient rigidity is obtained without overlapping. Moreover, the part which couple | bonds a cover member may be the side surface of either side of a recessed part, and may be the other structural surface of the front surface of a recessed part, or a seat cushion.

  Further, the direction in which the cover surface portion of the cover member is directed may be upward as shown in FIGS. 6 and 7 or may be forward. In addition, a plurality of cover members may be provided such that the cover members are set on the side surfaces on both sides of the recess, and the support member of the buckle may be covered from more than one side or covered in multiple layers. Moreover, the 2nd stitching | suture part may be set to the front edge part and center part of the surface width direction of a cover member, and the setting number may also be plural. Moreover, the 1st coupling | bond part of this invention and the 2nd coupling | bond part may not be the coupling | bonding by sewing, but may be based on various coupling means, such as adhesion | attachment, button coupling | bonding, and coupling | bonding by a hook_and_loop | surface fastener.

  In addition, the setting region of the second coupling portion does not necessarily have to be half of the surface width direction, and is appropriately set according to usage conditions such as the rigidity of the cover member and the direction in which the folded surface portion is to be directed. What is necessary is just to set an area. In addition, the second coupling portion does not necessarily have to be coupled with the base portion of the folded-up surface portion of the cover member aligned with the third portion surface. A configuration may be adopted in which the portion or the tip portion is suspended from the third part surface with a suture or the like and held in a bent state.
