  FIG. 6 is an exploded perspective view of the seat portion 2. The seat 2 includes a seat base 35, a seat 36 at the top of the seat base 35, and a tilt part 43 at the left and right front sides of the seat base 35.

  The seat base 35 made of synthetic resin fixes the upper surface portion 35a for fixing the seat portion 36 on which the user sits and the left and right tilt portions 43 that contact the inner side of the user's knee straddling the seat portion 36. And both side surface portions 35b.

  As shown in a cross section in FIG. 7, the seating portion 36 includes a base 37, a urethane foam (cushion) 38 is provided on the upper surface of the base 37, and the upper surface of the urethane foam 38 is covered with a skin 39. ing. The base 37 of the seating portion 36 is fixed to the seat portion housing 40 with screws 41.

  As shown in FIG. 6, a plurality of positioning bosses 40 a are provided on the lower surface of the seat housing 40, and the positioning bosses 40 a are inserted into the same number of positioning holes 35 c formed in the upper surface portion 35 a of the seat base 35. Each is fitted and fixed with a bolt or the like.

  As shown in FIGS. 8 and 9, the tilted portion 43 is formed in a large, substantially elliptical shape that is long in the front-rear direction when viewed from the side. The tilt portion 43 includes a base 44, and a urethane foam (cushion) 45 is provided on the upper surface of the base 44, and the upper surface of the urethane foam 45 is covered with a skin 46.

  A plurality of positioning bosses 44a are provided on the lower surface of the base 44. As shown in FIG. 6, each positioning boss 44a is fitted in the same number of positioning holes 35d formed on both side surfaces 35b of the seat base 35, respectively. And is fixed by bolts or the like.

  In FIG. 6, a stirrup 47 is suspended and supported on the inner surface portions of both side surface portions 35 b of the seat base 35.

  As shown in FIGS. 8 to 11, the base 44 itself of the tilt part 43 has a ring shape with an upper surface opened in a substantially elliptical shape, and the switch plate 48 fitted into the opening 44 b with a gap t therebetween. Is arranged.

  In the gap t, four arcuate hinge arms (spring plates) 49 are arranged at substantially equal angular intervals on the circumference, and one end of each hinge arm 49 is locked to the outer peripheral edge of the switch plate 48, The other end of each hinge arm 49 is locked to the inner peripheral edge of the opening 44 b of the base 44. As a result, the switch plate 48 is spring-supported in the opening 44 b of the base 44 and is normally biased so as to be substantially flush with the upper surface of the base 44. When the switch plate 48 receives pressure when the knee is sandwiched, the switch plate 48 moves inward of the base 44 against the spring force. Further, the four hinge arms 49 support the switch plate 48 so as to be substantially parallel movable.

  A sensor frame 50 is fixed with screws to a plurality of frame bosses 44c at substantially the center position in the major axis direction of the base 44, and a pressure sensor 51 facing the switch plate 48 is screwed to the center of the sensor frame 50. It is fixed with.

  Therefore, when the switch plate 48 receives pressure when the knee is sandwiched and moves inward of the base 44 against the spring force, the switch plate 48 presses the pressure sensor 51. The pressure sensor 51 detects the pinching force of the user's knee via the switch plate 48.

It comes to be. As a result, the switch plate 48 is supported by the guide sleeve 52 and the guide boss guide so as to be more accurately and substantially parallel movable.

  Pressed by the movement of the switch plate 48, the hinge arm 49, which is a support member (including a guide sleeve 52 and a guide boss if necessary) that supports the switch plate 48 so as to be substantially parallel movable. Sometimes, the pressure sensor 51 that detects the pressing force as the pinching force constitutes a detecting means. In addition, the detection means should just be provided in at least one of the tilt part 43 of the left-right front side part.

  In the case of the seat portion 2 of the oscillating motion apparatus 1 as described above, a seat portion 36 is provided on the upper portion of the seat portion base 35, and a tilt portion 43 is provided on the left and right front sides of the seat portion base 35. . As described above, the seat portion 36 and the tilt portion 43 are completely separated from each other, and the tilt portion 43 is provided with the pressure sensor 51 for detecting the pinching force of the user's knee.

  Therefore, even if the seating portion 36 is distorted and deformed during swinging, the pressure sensor 51 of the tilt portion 43 is not affected by the influence. Further, since the seating portion 36 and the tilting portion 43 are completely separated, the position of the tilting portion 43 is easy to understand visually and is easily pinched with knees, so that the shift of the seating position of the user is reduced. As a result, knee pressure can be accurately detected, and the user can be encouraged to take an accurate driving posture.

  Furthermore, since the seat portion 2 is divided into the seat portion base 35, the seat portion 36, and the tilt portion 43, each part is smaller than the case where the seat portion 36 and the tilt portion 43 are integrally formed. The molding dies for each part are also small and inexpensive, and manufacture is easy.

  Further, since the tilting portion 43 is substantially elliptical, the position of the tilting portion 43 can be easily understood by eyes, and the pressure of the knee can be detected more accurately.

  Further, the switch plate 48 of the tilt portion 43 is supported by four hinge arms 49 so as to be substantially parallel movable. Accordingly, the switch plate 48 can move substantially in parallel to press the pressure sensor 51 regardless of the position at which the knee is sandwiched at any position on the switch plate 48, so that the knee pressure can be detected more accurately. become. In particular, when the guide sleeve 52 and the guide boss (not shown) are provided, the switch plate 48 can be supported so as to be able to move in a substantially parallel manner.

  Instead of providing one pressure sensor 51 for the switch plate 48 as in the above-described embodiment, two pressure sensors 51 are provided for the switch plate 48 as shown in FIG. Can do. Alternatively, four pressure sensors 51 can be provided for the switch plate 48 as shown in FIG.

  Thus, by using the plurality of pressure sensors 51, the knee pressure can be detected more accurately.

  That is, as shown in FIG. 12A, by disposing the pressure sensors 51 at the two corners in the long axis direction, even if the pressure point shift in the long axis direction occurs, Can receive.

  Further, as shown in FIG. 12B, by disposing the pressure sensors 51 at the four corners in the major axis direction and the minor axis direction, it is possible to deal with pressure point deviations in all directions. In this case, the guide sleeve 52 and the guide boss (not shown) that support the switch plate 48 so as to be substantially parallel movable are also unnecessary.

  FIG. 13 shows a modified example. Instead of providing the four hinge arms 49 as in the above embodiment, the inner periphery of the opening 44 b of the base 44 and the outer periphery of the switch plate 48 are connected by a hinge 53. Thus, the switch plate 48 can be supported by the base 44 so as to be substantially parallel movable. In this case, the switch plate 48 detects the pressing force as a pinching force when the pressure sensor 51 is pressed by the movement of the switch plate 48, assuming that the switch plate 48 is in light contact with the pressure sensor 51.
