The present invention relates to a sheet having a hanging portion in which a skin material is suspended.

In a seat provided with a pad and a skin material covering the pad, a hanging portion linearly recessed may be provided on the seating surface of the seat cushion and the seat back in order to maintain the appearance shape. The skin material is suspended from the hanging portion and fixed to the engaging member fixed to the pad. For example, Patent Document 1 describes a hanging portion formed by locking a hanging edge portion (suspender) of a skin material with a clip installed in a groove of a pad. The clip includes a base portion and a pair of locking portions extending from the base portion, and the hanging edge portion of the skin material is locked by the pair of locking portions.

The pad is made of a foamed resin having cushioning properties such as urethane foam. The pad foam-molded in the mold is removed from the mold and then crushed by roller crushing. Roller crushing is a process performed to break the film (cell) of air bubbles generated during foam molding of a foamed resin and stabilize the hardness and settling characteristics of the pad. In the clip described in Patent Document 1, the rising portion provided on the outside of the pair of locking portions abuts on the pair of locking portions elastically deformed by the rollers during roller crushing, thereby engaging the pair. It prevents the stop from being excessively deformed.

The intermediate portion clip 9b may have the same structure as the end portion clip 9a, but may have a structure in which the extension portion 17 is omitted. The clip 9 is made of resin and is manufactured by injection molding or the like. The clip 9 is embedded in the pad 6 by being arranged in the mold of the pad 6 when the pad 6 is foam-molded.

The base portion 15 has a substantially flat plate shape orthogonal to the thickness direction, and has a plurality of through holes 18 penetrating in the thickness direction. The through hole 18 is filled with the foamed resin constituting the pad 6. The locking portion 16 includes a pair of locking pieces 19 arranged so as to be offset from each other in the extending direction and the width direction of the hanging groove 8. The base end side of the pair of locking pieces 19 is embedded in the pad 6, and the free end of the pair of locking pieces 19 protrudes from the pad 6. Each of the pair of locking pieces 19 extends from the free end in a direction close to each other in the width direction of the hanging groove 8 and locks the locked portion 13 of the hanging edge portion 11. Includes 20. When viewed from the thickness direction, the extending end edges of the pair of locking claws 20 are parallel to each other, and the distance between the extension lines of the extending end edges is equal to or greater than the width of the locked portion 13. Further, the shortest distance between the pair of locking claws 20 in the width direction of the hanging groove 8 is less than the width of the locked portion 13. The distance from the bottom surface of the hanging groove 8 to the locking claw 20 is the height of the locked portion 13 (the length from the surface facing the bottom surface of the hanging groove 8 to the surface abutting the locking claw 20). It is preferable that they are approximately equal.

The extension portion 17 extends from each of the base extension portion 21 extending from the base portion 15 in both the extending directions of the hanging groove 8 and the locking claws 20 in the extending direction of the hanging groove 8 so as to be separated from each other. Includes a free end extension portion 22 to be ejected. Of the two base extension portions 21 in each of the end clip 9a, the tip end portion of the base extension portion 21 on the side extending toward the positioning protrusion 14 is on the back surface side with respect to the positioning protrusion 14 in the pad 6. It has rushed into the adjacent part. Of the two free end extension 22s in each of the end clips 9a, the tip of the free end extension 22 extending toward the positioning protrusion 14 has entered the positioning protrusion 14. ..

The side surface of the positioning protrusion 14 on the end clip 9a side is an inclined surface 23 that is inclined so that the surface side is separated from the end clip 9a on the surface side in the thickness direction of the portion where the free end extension portion 22 has entered. include. The end of the skin extension portion 12 of the hanging edge portion 11 in the extending direction includes the inclined edge 24 facing the inclined surface 23.

The pad 6 has an individual easily deformable portion 25 corresponding to each of the clips 9 in the portion of the pad 6 forming the bottom of the hanging groove 8 and which is more easily deformed than the portion of the pad 6 around the pad 6. The easily deformable portion 25 includes a recess provided on the back surface of the pad 6. The recess is defined by the foamed resin that constitutes the pad 6. In the extending direction and the width direction of the hanging groove 8, both ends of the clip 9 are located inward of both ends of the easily deformable portion 25. Preferably, the contour of the clip 9 is located inside the contour of the easily deformable portion 25 when viewed from the thickness direction. Therefore, the easily deformable portion 25 also exists on the back surface side in the thickness direction of the portion of the positioning protrusion 14 where the extension portion 17 of the end clip 9a has entered. Further, the bottom surface of the concave portion constituting the easily deformable portion 25 is parallel to the bottom surface of the base portion 15 of the corresponding clip 9 and the bottom surface around the easily deformable portion 25 in the pad 6, and corresponds to the bottom surface of the base portion 15 of the clip 9. The distance to the bottom surface of the concave portion forming the easily deformable portion 25 is longer than the depth of the concave portion forming the easily deformable portion 25.

A member (not shown) for preventing abnormal noise from being generated between the pad 6 and the metal frame (not shown) arranged on the back surface side of the pad 6 is provided on the back surface side of the pad 6. If so, the easily deformable portion 25 may include a through hole provided in the abnormal noise generation prevention member. Further, the easily deformable portion 25 may be made of a foamed resin that is more easily deformable than the portion of the pad 6 around the concave portion instead of the concave portion.

As shown in FIG. 5, in the seat back 3, the clip 9 and the easily deformable portion 25 are arranged so as to avoid the central portion in the left-right direction of the seat back 3. Further, the wire 27 that supports the support member 26 includes a bent portion 28 for increasing the amount of bending of the wire 27 at a position that substantially coincides with the easily deformable portion 25 in the vertical direction and the horizontal direction. When a vehicle collides with another vehicle or another object and a large load is applied to the seat back 3 from the occupant, the pad 6 compresses the occupant's back to sink into the seat back 3 to alleviate the impact applied to the occupant. do. At this time, since the easily deformable portion 25 is arranged so as to avoid the central portion in the left-right direction of the seat back 3, the easily deformable portion 25 does not hinder the impact mitigation function of the pad 6. Further, the presence of the bent portion 28 of the wire 27 at a position substantially coincident with the easily deformable portion 25 in the vertical direction and the horizontal direction also contributes to the improvement of the amount of sinking of the occupant into the seat back 3.

A method of attaching the hanging edge 11 to the clip 9 will be described with reference to FIG. First, as shown in FIG. 6A, the worker tilts the locked portion 13 in the width direction with respect to the extending direction of the hanging groove 8 (see FIGS. 2 to 4). do. Next, as shown in FIG. 6B, the worker inserts the locked portion 13 between the pair of locking claws 20. Since the distance between the extension lines of the extending end edges parallel to each other of the pair of locking claws 20 is equal to or larger than the width of the locked portion 13, it is easy to tilt the locked portion 13 in the width direction. The locked portion 13 can be inserted between the pair of locking claws 20. Next, as shown in FIG. 6C, the worker passes the locked portion 13 through the center of the clip 9 and parallel to the thickness direction so as to be parallel to the extending direction of the hanging groove 8. Rotate around the axis. Since the shortest distance between the pair of locking claws 20 in the width direction of the hanging groove 8 is less than the width of the locked portion 13, in the state shown in FIG. 6C, the hanging edge portion 11 is on the surface. Even if pulled to the side, the locked portion 13 is locked to the pair of locking claws 20.

The action and effect of the sheet 1 according to the embodiment will be described. The pad 6 receives a force in the thickness direction from the roller during roller crushing during the manufacturing process. At this time, since the easily deformable portion 25 is provided on the back surface side in the thickness direction with respect to the clip 9, the clip 9 is displaced toward the easily deformable portion 25. Therefore, it is possible to prevent an excessive force from being applied from the roller to the clip 9. After passing through the roller, the clip 9 returns to its original position due to the elasticity of the pad 6. Further, in the extending direction and / or the width direction of the hanging groove 8, both ends of the clip 9 are located inward of both ends of the easily deformable portion 25, preferably, the clip is viewed from the thickness direction. Since the contour of 9 is located inside the contour of the easily deformable portion 25, the clip 9 is easily displaced toward the easily deformable portion 25 during roller crushing, and the force applied from the roller to the clip 9 is suppressed. .. Therefore, deformation and displacement of the clip 9 can be suppressed, and deterioration of the design of the hanging portion 5 can be suppressed.

Since each clip 9 is provided with an individual easily deformable portion 25, the reaction force of the pad 6 to the roller is larger in the portion where the clip 9 does not exist than in the portion where the clip 9 exists. Therefore, the force applied to the clip 9 from the roller is suppressed. Further, since each clip 9 is provided with an individual easily deformable portion 25, the ratio of the region where the easily deformable portion 25 is formed to the entire pad 6 becomes small when viewed from the thickness direction, and the cushioning property is improved. Can be suppressed.

Since the easily deformable portion 25 includes a recess, it becomes easy to form the easily deformable portion 25 on the pad 6. Further, the distance from the bottom surface of the base portion 15 of the clip 9 to the bottom surface of the concave portion constituting the corresponding easily deformable portion 25 is longer than the depth of the concave portion forming the easily deformable portion 25, so that the easily deformable portion 25 is pad 6 It suppresses the decrease in the holding force of the clip 9 due to the above.

The provision of the positioning protrusion 14 facilitates positioning of the hanging edge portion 11 in the hanging groove when the hanging edge portion 11 is inserted into the hanging groove 8.

The tip of the base extension 21 of the end clip 9a plunges into a portion adjacent to the back surface side of the positioning protrusion 14 of the pad 6, and the tip of the free end extension 22 of the end clip 9a is formed. By plunging into the positioning protrusion 14, the supporting force of the end clip 9a by the pad 6 is improved. Further, the support force of the end clip 9a by the pad 6 is also improved by filling the through hole 18 provided in the base 15 of the clip 9 with the foamed resin constituting the pad 6.

Since the extension portions 17 are provided on both sides of the end clip 9a in the longitudinal direction, it is possible to prevent the end clip 9a from being assembled to the pad 6 in the wrong direction.

Since the positioning protrusion 14 partially overlaps the easily deformable portion 25 in the thickness direction of the pad 6, the positioning protrusion 14 can compensate for the decrease in cushioning property of the pad 6 due to the provision of the easily deformable portion 25. In addition, the pad 6 can be made more compact in the extending direction of the hanging groove 8 as compared with the case where the positioning protrusion 14 and the easily deformable portion 25 do not overlap each other.

Since the positioning protrusion 14 is provided with the inclined surface 23, it is possible to prevent the skin extension portion 12 of the hanging edge portion 11 from colliding with the positioning protrusion 14.

Since the base end portion of the pair of locking pieces 19 is embedded in the pad 6, the foamed resin constituting the pad 6 is also inserted between the pair of locking pieces 19. Therefore, the portion of the pad 6 that has entered between the pair of locking pieces 19 prevents the locked portion 13 from moving to the back surface side in the thickness direction.

The first to third modifications of the above embodiment will be described with reference to FIGS. 7 to 9. The same reference numerals are given to the configurations common to the above embodiments, and the description thereof will be omitted.

In the first modification shown in FIG. 7 and the second modification shown in FIG. 8, the first surface fastener 31 attached to the bottom of the hanging groove 8 and the thickness direction of the locked portion 13 of the hanging edge portion 11 It differs from the above embodiment in that it includes a second surface fastener 32 attached to the surface on the back surface side of the above and engaged with the first surface fastener 31. The first and second hook-and-

loop fasteners

31 and 32 are arranged at positions separated from the clip 9 in the extending direction of the hanging groove 8. In the first modification, the first hook-and-loop fastener 31 is arranged in the vicinity of the positioning protrusion 14, the second hook-and-loop fastener 32 is arranged at the end of the hanging edge portion 11 in the extending direction, and the end clip 9a The extension portion 17 of the above does not rush into the positioning protrusion 14 and the portion in the vicinity thereof. In the second modification, the first hook-and-loop fastener 31 is arranged in the middle of the clips 9 adjacent to each other, and the second hook-and-loop fastener 32 is arranged in the middle portion of the hanging edge portion 11 in the extending direction.

When the hanging edge portion 11 is attached to the clip 9, an excessive force is applied from the hanging edge portion 11 to the clip 9, the position of the clip 9 with respect to the pad 6 may shift, and the design of the hanging portion 5 may deteriorate. be. Therefore, by engaging the first and second hook-and-

loop fasteners

31 and 32 with each other and then attaching the hanging edge portion 11 to the clip 9, it is possible to prevent an excessive force from being applied from the hanging edge portion 11 to the clip 9. Therefore, it is possible to prevent the clip 9 from being displaced with respect to the pad 6, and it is possible to suppress deterioration of the design of the hanging portion 5.

The third modification shown in FIG. 9 is different from the above embodiment in that the positioning protrusion 14 is provided with a slit 33 through which the hanging edge portion 11 is inserted. In the extending direction of the suspension groove 8, the tip of the base extension portion 21 is preferably located on the distal side of the end of the slit 33.
