  • a locking projection that restricts the displacement of the tightening cord to a base plate center side is provided on a lower surface side of such a chair, and thereby, positional deviation of the upholstery material is prevented.
  • the upholstery material can be easily attached to the cushion material and the base plate by tightening the tightening cord in the shape of a loop on the lower surface side of the base plate and tying the end parts. Moreover, variations in the tension that acts on the upholstery material can be reduced by managing the length of the tied part of the tightening cord.
  • an object of the invention is to provide a chair that can appropriately restrict displacement of a tightening cord and a peripheral edge of an upholstery material and can reduce positional deviation of an upholstery material.
  • a chair related to the invention includes a load-supporting body.
  • the load-supporting body includes a base plate constituting a framework; a cushion material arranged on a front surface side of the base plate; an upholstery material stretched to cover at least an outside surface of the cushion material and an outer peripheral edge of the base plate; and a tightening cord inserted through a peripheral edge of the upholstery material and tightened to allow end parts to be tied together on a rear surface side of the base plate in a state in which the upholstery material has covered the outside surface of the cushion material and the outer peripheral edge of the base plate.
  • the base plate is provided with first locking means for restricting displacement of the tightened tightening cord in a base-plate center direction, and second locking means for restricting displacement of the tightened tightening cord in a base plate outward direction.
  • the base plate may be formed in a substantially rectangular shape having corner parts at four corners and linear parts between the corner parts, the corner parts may be provided with the first locking means, and at least some of the linear parts may be provided with the second locking means.
  • the first locking means include a first side wall protruding from a rear surface of the base plate to a rear side, and a first protruding wall protruding in an outward direction of the base plate from the vicinity of a protruding end of the first side wall
  • the second locking means may include a second side wall protruding from the rear surface of the base plate to the rear side, and a second protruding wall protruding in an inward direction of the base plate from the vicinity of a protruding end of the second side wall.

  • the tightening cord or the peripheral edge of the upholstery material can be arranged inside the first protruding wall or the second protruding wall, pushing the tightening cord or the peripheral edge of the upholstery material into the recessed groove that is continuous in the peripheral direction of the base plate. Therefore, the upholstery material can be easily attached. Additionally, since the tightening cord or the peripheral edge of the upholstery material is arranged within the recessed groove that is continuous in the circumferential direction of the base plate, the upholstery material is not more easily curled.
  • the first protruding wall and the second protruding wall is arranged so as to be separated from each other in a direction in which the tightening cord extends, and to be adjacent to each other.
  • respective tip parts of the first protruding wall and the second protruding wall that are provided adjacent to each other extend to positions with substantially half lengths of the separation width of the first side wall and the second side wall in a direction intersecting the direction in which the tightening cord extends.
  • Tip parts of the first protruding wall and the second protruding wall may be arranged at positions that face each other.
  • the tip parts of the first protruding wall and the second protruding wall are arranged to face each other, even if the displacement direction of the tightening cord or the peripheral edge of the upholstery material varies, the displacement of the tightening cord or the peripheral edge of the upholstery material is reliably restricted by any one of the first protruding wall and the second protruding wall.
  • Portions of tip parts of the first protruding wall and the second protruding wall may be arranged to face each other, and remaining portions thereof may be arranged so as to be separated from each other in a direction in which the tightening cord extends.
  • the displacement of the tightening cord or the peripheral edge of the upholstery material is reliably restricted by any one of the first protruding wall and the second protruding wall.
  • the first protruding wall and the second protruding wall extend to be long along the direction in which the tightening cord extends. For this reason, the first protruding wall and the second protruding wall can be easily bent and deformed when the tightening cord or the peripheral edge of the upholstery material is attached. Therefore, this can facilitate the attachment of the upholstery material.

  • the upholstery material 15 is covered to hold the outside surface of the cushion material 14 and the outer peripheral edge of the base plate 13, and the peripheral edge 15a of the upholstery material 15 is fitted into the recessed groove 19 of the base plate 13 together with the tightening cord 18 on the lower surface side of the base plate 13.
  • the tightening cord 18 and the peripheral edge 15a of the upholstery material 15 ride over only the first protruding wall 26 and are pushed into the recessed groove 19.
  • the first protruding wall 26 and the second protruding wall 27 ride over the tightening cord 18 and the peripheral edge 15a of the upholstery material 15 and are pushed into the recessed groove 19.
  • both end parts of the tightening cord 18 pulled out from the insertion hole part 17 of the peripheral edge of the upholstery material 15 are tightened using an appropriate instrument, and both the end parts of the tightening cord 18 are tied together in that state.
  • the tightening of the tightening cord 18 can also be manually performed by a worker.
  • the displacement, in the base-plate center direction, of the tightening cord 18 and the peripheral edge 15a of the upholstery material 15 is restricted by the first side wall 24 and the first protruding wall 26, and the displacement, in the base plate outward direction, of the tightening cord 18 and the peripheral edge 15a of the upholstery material 15 is restricted by the second side wall 25 and the second protruding wall 27.
  • the second side wall 25 and the second protruding wall 27 that are the second locking means in addition to the first side wall 24 and the first protruding wall 26 that are the first locking means are provided at suitable positions on the lower surface of the base plate 13 of the seat body 4. Therefore, not only the displacement of the peripheral edge 15a of the upholstery material 15 that tends to narrow inward but also the displacement thereof that tends to widen outward can be appropriately restricted. For this reason, curling of the upholstery material 15 in various directions can be more reliably suppressed.
  • the second side wall 25 and the second protruding wall 27 are provided in the linear parts 13b on both the left and right sides of the base plate 13 and the linear part 13b on the front side in the thick cushion material 14 superimposed on an upper surface. Therefore, the displacement of the peripheral edge 15a of the upholstery material 15 that tends to widen outward accompanying the tightening of the tightening cord 18 can be appropriately restricted.
  • the first locking means is constituted of the first side wall 24 and the first protruding wall 26, and the second locking means is constituted of the second side wall 25 and the second protruding wall 27. Therefore, slip-out of the peripheral edge 15a of the upholstery material 15 from the recessed groove 19 can be reliably restricted by the first protruding wall 26 and the second protruding wall 27. In addition, even in a case where the tightening cord 18 or the peripheral edge 15a of the upholstery material 15 directly abuts against neither the first protruding wall 26 nor the second protruding wall 27, the displacement of the tightening cord 18 or the upholstery material 15 can be restricted by the first side wall 24 and the second side wall 25 that are walls of the recessed groove 19.
  • the recessed groove 19 is provided in the lower surface of the base plate 13 so as to be continuous in the circumferential direction of the base plate 13, the first side wall 24 is constituted of an inside wall of the recessed groove 19, and the second side wall 25 is constituted of an outside wall of the recessed groove 19. Therefore, when the upholstery material 15 is attached, the tightening cord 18 or the peripheral edge 15a of the upholstery material 15 can be easily arranged inside the first protruding wall 26 or the second protruding wall 27, continuously pushing the tightening cord 18 or the peripheral edge 15a of the upholstery material 15 into the recessed groove 19 on the base plate 13. For this reason, the upholstery material 15 can be easily attached. Moreover, since the displacement of the tightening cord 18 or the peripheral edge 15a of the upholstery material 15 is restricted within the continuous recessed groove 19, the curling of the upholstery material 15 can be made less likely to occur.
  • the continuous recessed groove 19 may not necessarily be formed in the lower surface of the base plate 13.
  • the first side wall 124 and the second side wall 125 that are narrow may intermittently protrude from the lower surface of the base plate 113 so as to run along the direction in which the tightening cord 18 extends, and the first protruding wall 126 and the second protruding wall 127 may be respectively provided continuously with the vicinities of the respective protruding ends of the first side wall 124 and the second side wall 125.
  • the first protruding wall 26 and the second protruding wall 27 provided in the linear parts 13b are arranged so as to be separated from each other in the direction in which the tightening cord 18 extends, and to be adjacent to each other. Therefore, the length of the first protruding wall 26 and the second protruding wall 27 can be sufficiently extended without causing any contact between tip parts of the first protruding wall 26 and the second protruding wall 27. For this reason, the first protruding wall 26 and the second protruding wall 27 can be easily bent and deformed when the tightening cord 18 or the peripheral edge of the upholstery material 15 is attached. Therefore, this can facilitate the attachment of the upholstery material 15.
  • the respective tip parts of the first protruding wall 26 and the second protruding wall 27 that are provided adjacent to each other in the linear parts extend to positions with substantially half lengths of the groove width (the separation width of the first side wall 24 and the second side wall 25) of the recessed groove 19. Therefore, the wide range of the recessed groove 19 is blocked by the first protruding wall 26 and the second protruding wall 27, and the slip-out of the peripheral edge 15a (tightening cord 18) of the upholstery material 15 from the inside of the recessed groove 19 can be effectively prevented.
  • the respective tip parts of the first protruding wall 26 and the second protruding wall 27 are extended to the positions with substantially half lengths of the groove width of the recessed groove 19, if minimal setting is made so that the tightening cord 18 can pass through the recessed groove at least, the work of putting the peripheral edge 15a of the upholstery material 15 into the recessed groove 19 is not hindered by the first protruding wall 26 and the second protruding wall 27.
  • FIG. 9 is a view illustrating lower surfaces of main parts of a base plate 213 of a third embodiment.
  • tip parts of a first protruding wall 226 and a second protruding wall 227 provided in the linear parts are arranged at positions that face each other.
  • the tip parts of the first protruding wall 226 and the second protruding wall 227 are arranged to face each other. Therefore, even if the displacement direction of the tightening cord 18 or the peripheral edge 15a of the upholstery material 15 varies, the displacement of the tightening cord 18 or the peripheral edge 15a of the upholstery material 15 can be reliably restricted by any one of the first protruding wall 226 and the second protruding wall 227.
  • FIG. 10 is a view illustrating lower surfaces of main parts of a base plate 313 of a fourth embodiment of the invention.
  • portions of tip parts of a first protruding wall 326 and a second protruding wall 327 provided in the linear parts face each other, and remaining portions thereof are arranged so as to be separated from each other in a direction in which the tightening cord 18 extends.
  • the displacement of the tightening cord 18 or the peripheral edge 15a of the upholstery material 15 can be reliably restricted by any one of the first protruding wall 326 and the second protruding wall 327.
  • the first protruding wall 326 and the second protruding wall 327 extend to be long along the direction in which the tightening cord 18 extends. For this reason, the first protruding wall 326 and the second protruding wall 327 can be easily bent and deformed when the tightening cord 18 or the peripheral edge 15a of the upholstery material 15 is attached. For this reason, the attachment of the upholstery material 15 can be facilitated.
  • the invention is not restricted to the above embodiments, and various design changes can be made.
  • the above embodiments exemplify a load-supporting body as a seat body, it is also possible to adopt the same structure for a backrest body of the backrest part.
