  The structure of the seat 10 for hall | holes which is a seat in the attitude | position change system 1 of the seat of one Embodiment of this invention is demonstrated using FIGS. In the following description, when directions such as front / rear, up / down, left / right, and the like are indicated, the directions shown in the drawings are indicated.

  As shown in FIGS. 1 and 2, the hall seat 10 is attached to the floor F through a slide rail 20 so as to be movable in the front-rear direction. Here, the hall seat 10 corresponds to a “seat” in the claims.

  The hall seat 10 includes a frame 11 that forms a skeleton, a seat cushion 12 that is supported by the frame 11 and serves as a seating surface, and a seatback 13 that is supported by the frame 11 and serves as a backrest for a seated person. It is said that. Here, the seat cushion 12 corresponds to a “seat surface portion” in the claims.

  As shown in FIGS. 1 and 2, the frame 11 is formed by assembling mainly a square pipe material having a rectangular cross section. An upper frame portion 11a that is formed in a substantially U shape having an opening in front when viewed from above and extends substantially horizontally, and an open end that is formed in a substantially U shape that has an opening in front when viewed from above is used as the opening end of the upper frame portion 11a. And a pair of left and right connecting portions 11c for connecting the rear portion of the lower frame portion 11b and the rear end portion of the lower frame portion 11b in a substantially vertical direction. And a pair of left and right front legs 11d extending obliquely forward and downward slightly from the rear center of the lower frame 11b, and a rear leg 11e extending downward from the rear end of the lower frame 11b. At the lower part of each connecting portion 11c, a first recliner 11f that adjusts the flip-up angle of the seat cushion 12 to a position above the lower frame portion 11b, and the inclination of the seat back 13 at the same height as the lower frame portion 11b A second recliner 11g for adjusting the angle is disposed. On the upper surface of the left side portion of the upper frame portion 11a, a display 11a2 for operating the first recliner 11f to change the posture of the seat cushion 12 and instruct to leave is disposed, as will be described later. Here, the first recliner 11f corresponds to “switching means” in the claims, and the display 11a2 corresponds to “change instruction means” in the claims.

  The first recliner 11f and the second recliner 11g are of an electric type and start rotating when an operation button (not shown) disposed on the frame 11 is pressed, and stop rotating when a limit switch described later is pressed. Then, it is configured to be in a locked state. A caster 11d1 that can move back and forth is attached to the lower end of each front leg 11d. The caster 11d1 abuts on the floor F and rotates to change the position of the front leg portion 11d in the front-rear direction. Although not shown in FIGS. 1 and 2, the frame 11 is covered with a resin cover member and has a good appearance.

  As shown in FIG.1 and FIG.2, the seat cushion 12 is formed in the shape used as a substantially V-shape by which side view is horizontal. Specifically, the seating posture position C1 indicated by a solid line in FIGS. 1 and 2 includes a first support surface portion 12a that faces upward and a second support surface portion 12b that faces front and lower. In the seat cushion 12 in the sitting posture position C1, the first support surface portion 12a is formed with the first support surface 12a1 that is the upper surface thereof as a substantially flat surface, and the second support surface portion 12b is the second lower surface that is the front lower surface. The support surface 12b1 is formed as a concave surface whose central portion is recessed rearward and upward. Then, the seated person P can sit on the first support surface 12a1 of the seat cushion 12 at the sitting position C1 in a sitting position with his / her waist down. Further, the second support surface 12b1 forms a pull-in surface that is pulled down rearward, and when the seated person P sits on the first support surface 12a1, the lower leg portion is rearward. A space that can be pulled in is formed. The seat cushion 12 is formed by placing cushion pads 12a2 and 12b2, which are cushion materials, on a cushion frame (not shown) forming a skeleton, and covering them with cushion covers 12a3, 12b3 which are skin materials. . That is, the first support surface 12a1 of the first support surface portion 12a and the second support surface 12b1 of the second support surface portion 12b are formed so as to softly contact and support the body of the seated person P. The seat cushion 12 is attached to the connecting portion 11c of the frame 11 via the first recliner 11f on the rear end side of the cushion frame at the sitting posture position C1.

  When the operation button is pressed while the seat cushion 12 is in the sitting posture position C1, the seat cushion 12 rotates clockwise around the rotation axis of the first recliner 11f in FIG. 2, and the front end side is flipped up. . The limit switch 11h (see FIG. 5) disposed on the frame 11 is then flipped up 90 degrees or more rearward from the sitting posture position C1 to the standing posture position C2 indicated by a two-dot chain line in FIG. ) Is pressed by the seat cushion 12, the rotation of the first recliner 11 f is stopped and the locked state is established. At this time, the second support surface portion 12b is pulled up to a position higher than the first support surface portion 12a in the sitting posture position C1, and the second support surface 12b1 forms a surface inclined in a front-lowering manner. It becomes possible to abut and support. A state in which the second support surface 12b1 forming the seating surface at the above-described standing posture position C2 forms a front-lowering surface so that the surface is widely directed toward the buttocks of the seated person P taking the standing posture. Thus, it becomes difficult to form an overhanging shape in which the front edge thereof bites into the buttocks of the seated person P. Therefore, the seated person P sitting on the second support surface portion 12b can take a standing posture with less fatigue feeling with a good sitting comfort with little foreign body feeling and with the angle of the pelvis approaching the angle at the standing posture. Here, the sitting posture position C1 and the standing posture position C2 correspond to a “second posture” and a “first posture” in the claims, respectively. Further, the limit switch 11h corresponds to “attitude determination means” in the claims.

  As shown in FIG. 2, a seating sensor 30 is disposed on the second support surface portion 12b. When the seat cushion 12 is in the standing posture position C2 and the seated person P is seated, the seating sensor 30 is arranged such that the pelvis of the seated person P in the cushion pad 12b2 is embedded at a corresponding position. Specifically, the seating sensor 30 has a rectangular surface shape and is disposed between the cushion cover 12b3 and the cushion pad 12b2. The seating sensor 30 outputs a signal to the computer 40 described later when the seated person P is seated on the second support surface 12b1. Here, the seating sensor 30 and the computer 40 correspond to “control means” and “seat determination means” in the claims, respectively.

  As shown in FIGS. 1 and 2, the seat back 13 is formed in a shape that is substantially I-shaped when viewed from the side. Specifically, in the sitting posture position B1 indicated by a solid line in FIGS. 1 and 2, the front surface serving as the backrest surface is formed so as to form a substantially flat inclined surface slightly inclined backward from the vertical. And the front surface of the seat back 13 in the sitting posture position B1 can support the back of the seated person P sitting in the sitting posture with the waist down. The seat back 13 is formed by placing a back pad (not shown) as a cushioning material on a back frame (not shown) forming a skeleton and covering the back pad 13a as a skin material thereon. . That is, the front portion of the seat back 13 is formed so as to be in soft contact with and support the body of the seated person P. The seat back 13 is attached to the connecting portion 11c of the frame 11 through the second recliner 11g on the lower end side of the back frame.

  When the operation button is pressed while the seat cushion 12 is in the sitting posture position C1 and the seat back 13 is in the sitting posture position B1, the seat back 13 in FIG. 2 rotates clockwise around the rotation axis of the second recliner 11g. Rotate to and fall back. When the seat back 13 presses a limit switch (not shown) provided on the frame 11 when the standing posture position B2 indicated by a two-dot chain line in FIG. 2 is reached, the second recliner 11g rotates. Stopped and locked. At this time, the seat back 13 is in a position where it does not contact the seat cushion 12 in the standing posture position C2. The seat back 13 moves from the sitting posture position B1 to the standing posture position B2 in a shorter time than the time from when the seat cushion 12 reaches the sitting posture position C2 to the sitting posture position C2. As a result, the seat cushion 12 and the seat back 13 are in a process in which the seat cushion 12 moves from the sitting position C1 to the standing position C2, and the seat back 13 moves from the sitting position B1 to the standing position B2. Do not interfere with each other. The seat back 13 does not come into contact with the body of the seated person P when in the standing position B2. The seat cushion 12 and the seat back 13 can be moved between the sitting posture positions C1 and B1 and the standing posture positions C2 and B2 by a signal from a computer 40 installed at a predetermined position on the floor F described later. ing. That is, the first recliner 11f and the second recliner 11g can be operated not only by the operation buttons but also by a signal from the computer 40.

  As shown in FIGS. 1 to 4, a plurality of pairs of left and right slide rails 20 are arranged on the floor F so as to extend in the front-rear direction in parallel with each other. The pair of left and right slide rails 20 are arranged so as to fit between the casters 11 d 1 of the front leg portion 11 d of the hall seat 10. As shown in FIG. 2, each slide rail 20 has a long lower rail 21 fixed to the floor F, and a short upper rail 22 attached to the lower rail 21 so as to be slidable in the extending direction of the lower rail 21. . A plurality of upper rails 22 are attached to one lower rail 21, and a lower end portion of a rear leg portion 11 e of the hole seat 10 is attached to each of the upper rails 22. In addition, each upper rail 22 is provided with a lock mechanism (not shown) that can lock and unlock the sliding with respect to the lower rail 21. As a result, each of the hall seats 10 can be moved in the front-rear direction with respect to the pair of left and right slide rails 20, and can be locked in a desired position and cannot be moved in the front-back direction. At this time, since the caster 11d1 is disposed on the outer side in the seat width direction of the pair of left and right slide rails 20, the caster 11d1 can smoothly move on the floor F.

  The operation of the hall sheet 10 will be described. In the normal state, the seat occupant of each seat is freely in the state where the seat cushion 12 is in the sitting posture position C1 and the seat back 13 is in the sitting posture position B1, or the seat cushion 12 is in the standing posture posture position C2. Is in a standing posture position B2 and is freely selected and used. That is, the seated person P of each seat freely switches between the sitting posture positions C1 and B1 and the standing posture positions C2 and B2 by operating the first recliner 11f and the second recliner 11g with the operation buttons. Is used. As shown in FIG. 3, in the normal state, the seat cushion 12 is in the sitting posture position C1 and the seat back 13 is in the sitting posture position B1, and the seat cushion 12 is in the standing posture posture position C2 and the seat back 13 is upright.
