  The present invention relates to a chair-type massage machine in which a massage mechanism for massage on the back of a human body is arranged in a backrest, and includes a seat cushion composed of two upper and lower layers arranged in a seat portion, and an upper layer side cushion and a lower layer side cushion. The seat cushion is connected at least at other portions except the front end side, and a flexible connecting piece whose front end is connected to the chair structure from the front end edge which is the free end of the upper side seat cushion is provided. It is characterized by being extended.

  The connecting piece preferably includes a cushion material and is bent obliquely downward, and the lower-layer seat cushion preferably includes a chamfered portion on the upper edge of the front end side.

  The structure to which the tip of the connecting piece is connected is preferably a frame of a footrest that is arranged to be pivotable up and down in front of the seat. In this case, it is preferable that the tip of the connecting piece is connected to a portion below the pivot shaft of the frame of the footrest.

  Further, the seat cushion may include an airbag that expands and contracts downward from the upper-layer seat cushion.

  In the present invention, since at least the front end side of the upper and lower two-layer seat cushions is not connected and the front end of the upper-layer seat cushion is connected to the structure by the connecting piece, a good sitting comfort is ensured. However, the seat cushion on the upper layer side can be prevented from shifting and the upper seat cushion does not hinder the inflation of the airbag even if it has an airbag. Is.

  If the connecting piece encloses the cushioning material and bends obliquely downward, the seating comfort can be further improved and the appearance can be kept good. If a chamfered portion is provided on the upper edge of the front end side of the cushion, it is possible to ensure better sitting comfort and better appearance.

  In addition, the structure to which the tip of the connecting piece is connected is a footrest frame that is arranged to be pivotable up and down in front of the seat, compared with the case where it is fixed to the frame below the seat. Thus, the gap between the footrest and the footrest can be hidden, the appearance can be improved, and the situation where the limbs are caught in the gap can be prevented. In particular, if the tip of the connecting piece is connected to a portion below the pivot shaft of the footrest frame, the tension applied to the seat cushion on the upper layer side according to the pivot of the footrest. Therefore, it is possible to obtain a preferable state both during massage and when the footrest is stored.

  Further, it is preferable that the seat cushion includes an airbag that expands and contracts below the seat cushion on the upper layer side because massage of the buttocks and thighs can be performed.

It is a side view at the time of reclining same as the above. (a) (b) is a side view of a seat part same as the above. It is a perspective view of the seat cushion of the other example same as the above. It is a perspective view of the seat cushion of the other example same as the above.

  The present invention will be described in detail based on an example of the embodiment. The chair-type massage machine shown in FIGS. 1 and 2 includes a massage mechanism (not shown) disposed in a reclining backrest 1. In addition to the backrest 1, the seat 2 and the armrests 3 and 3 located on both sides of the seat 2, the footrest 4 disposed below the front end of the seat 2, and the frame on which the seat 2 is disposed on the upper surface 5. The footrest 4 is pivotally supported on the upper part of the front end of the frame 5 and is rotatable about the shaft. By the rotation, the footrest 4 is substantially horizontal to the front side of the seat portion 2. Can be placed in a state. In the figure, the left armrest 3 is omitted.

  In the frame 5, in addition to a unit for rotationally driving the footrest 4 and a lift unit 51 responsible for the reclining operation of the backrest 1, an air pump and a valve for supplying air to each airbag described later Is arranged. In the figure, reference numeral 55 denotes a frame cover.

  As shown in FIG. 3, the lower portion of the backrest 1 is supported by a shaft 50 at the upper rear end of the frame 5, and an extension / contraction of a lift unit 51 disposed between the lower end and the upper front end of the frame 5. It can be reclined by rotating around a shaft 50, and is formed by covering a frame-shaped back frame 10 with a box-shaped frame 11 and further covering the frame 11 with an outer skin 12. The massage mechanism disposed in the backrest 1 is movable up and down along the backrest frame 10, and massage on the back of the human body is performed through the opening 13 provided on the front surface of the frame 11. It is performed by bringing the treatment element 6 into contact with the back of the human body through the outer skin 12.

  The armrest 3 includes a side plate 30 disposed on the side of the seat portion 2, a side cover 31 that covers the outer surface of the side plate 30, an armrest portion 32 that covers the upper surface of the side plate 30, and an armrest cover that is disposed on the upper surface of the armrest portion 32. The armrest cover 33 is connected to the armrest portion 32 at the front end side, and an air bag (not shown) is arranged on the surface facing the armrest portion 32, so that the upper surface of the armrest portion 32 and the armrest By inserting an arm between the cover 33 and inflating and contracting the airbag, the arm can be massaged.

  Further, as shown in FIGS. 3 and 4, the armrest 3 here has a rear end portion of the side plate 30 connected to the backrest 1 by a shaft 35 and connected to a front end portion of the side plate 30 by a shaft 37. Since the link 36 is connected to the frame 5 by the shaft 38, the angle of the upper surface changes in synchronization with the reclining operation of the backrest 1. However, in the example shown in the figure, the angle change of the upper surface of the armrest 3 is made smaller than the angle change of the backrest 1, and the angle α1 formed between the front surface of the backrest 1 and the upper surface of the armrest 3 when the backrest 1 is raised. While the angle is 115 °, the angle α2 formed by the front surface of the backrest 1 and the upper surface of the armrest 3 is 160 ° when the backrest 1 is laid down most.

  Compared to the case where only the backrest 1 is reclined and the armrest 3 does not move, the armrest 3 can be placed in a relaxed state when the backrest 1 is laid down, and the backrest 1 is also laid down. The arm (including the wrist and hand) can be massaged by the airbag in the armrest 3 even in the state where the arm rests.

  A side plate 60 fixed to the frame 5 is provided on the inner side surface (the surface on the seat portion 2 side) of the armrest 3, and an airbag 61 is disposed on the inner side surface of the side plate 60. By inflating and contracting the airbag 61, the side surface of the thigh can be massaged or fixed from the waist.

  Further, the backrest 1 here has a side wall 15 that protrudes forward, and an airbag 16 is disposed on the inner side surface of the side wall 15, so that massage members are provided on both upper sides of the backrest 1. However, projecting portions 14 and 14 projecting laterally are provided on both sides of the upper portion of the backrest 1, and the side wall 15 projects forward from the front surface of the projecting portion 14.

  The overhanging portion 14 has an upper end that is smoothly connected to the upper end of the backrest 1 and has a large overhang toward the lower side. The side wall 15 is also provided along the side edge of the overhanging portion 14. In addition, it has an inclination corresponding to the inclination of the side surface of the overhanging portion 14. In addition, the amount of forward protrusion of the side wall 15 is zero and increases toward the lower side on the upper end side of the backrest 1, so that the side wall 15 has a sense of unity with the backrest 1. In addition, the airbag 16 disposed on the inner side surface of the side wall 15 has a triangular outer shape that is larger on the lower side, like the side wall 15.

  As shown in FIG. 5, the seat portion 2 is provided with upper and lower two-layer seat cushions 21 and 22. These seat cushions 21 and 22 are connected at the rear end side, and a lower layer type seat cushion 22 is fixed to the frame 5, and is used for massaging the buttocks and thighs on the upper surface of the lower layer side seat cushion 22. A plurality of airbags 24 are arranged.

  Further, a connecting piece 23 connected to the upper surface side of the upper-side seat cushion 21 extends from the front end edge of the seat cushion 21, and the connecting piece 23 having flexibility (more preferably stretchable) has its tip. For example, a hook or a pin is connected to the frame 40 of the footrest 4 whose edge is rotatable up and down.

  In this massage machine, sitting on the seat 2 and depositing the back on the backrest 1, in this state, if the airbag 16 disposed inside the side wall 15 of the backrest 1 is inflated and contracted, massage the side of the human body from the shoulder to the upper arm. can do. In addition, if the human body is fixed to the backrest 1 by inflating the airbag 16, the massage mechanism arranged in the backrest 1 will not lift up from the backrest 1 when the body is pushed from behind with a treatment element. In addition, it is possible to effectively massage the back of the human body.

  The overhanging portion 14 including the side wall 15 is provided only on the upper portion of the backrest 1, and the side wall 15 is also provided within the range of the overhanging portion 14. For this reason, the overhanging portion 14 and the side wall 15 do not interfere with the arm placed on the armrest 1 when the reclining operation is performed. In addition, although the overhanging portion 14 protrudes laterally from the side surface of the backrest 1, the overhanging portion 14 does not protrude sideways from the armrests 3 and 3 arranged on both sides of the seat portion 2. The size when packing is not increased.

  Moreover, if the airbag 24 arranged on the seat portion 2 is inflated and contracted, massage on the buttocks and thighs can be performed. When the airbag 24 is inflated, the seat cushion 21 on the upper layer side is pushed up.

  Here, when massage is performed with this massage machine, the backrest 1 is usually reclined and the footrest 4 is rotated upward as shown in FIG. 5 (b). At this time, since the connecting piece 23 of the upper-layer seat cushion 21 is connected to the connected portion 42 located below the rotation shaft 41 of the frame 40 of the footrest 4, 4, the connecting piece 23 is slackened, and the front edge and both side edges of the upper-layer seat cushion 21 are not connected to the lower-layer seat cushion 21. The seat cushion 21 is not disturbed by the presence of the connecting piece 23, and the seat cushion 21 is not displaced even if the airbag 24 is repeatedly expanded and contracted.

  When the massage is finished and the footrest 4 is returned to the original state shown in FIG. 5 (a), the seat cushion 21 is pulled on the front end side by the rotation of the frame 40 of the footrest 4, so that the seat The cushion 21 can maintain a good-looking appearance with its surface tensioned. In addition, the connecting piece 23 also has a limb sandwiched in the gap between the seat 2 and the footrest 4. And if the connection piece 23 has a stretching property, since the seat cushion 21 can follow the larger bulge of the airbag 25, a treatment feeling can be improved.

  It is desirable to put a cushion material in the connecting piece 23 in that the feeling of the back of the knee when sitting on the seat 2 can be kept good. In this case, if the connecting piece 23 has a shape in which the steady state is directed obliquely downward as shown in FIG. Will improve. In addition, as shown in FIG. 6, if the front end upper portion of the lower side seat cushion 22 is a chamfered portion 26 formed of a curved surface or an inclined surface, it is possible to maintain a better state both in terms of sitting comfort and appearance.

  In the above-described embodiment, the upper and lower two-layer seat cushions 21 and 22 are connected only at the rear edge. However, any combination may be used as long as the airbag 24 is connected so as not to prevent the inflation of the airbag 24. As shown, the seat cushions 21 and 22 may be connected at the center in the front-rear direction and the center in the width direction.
