Reference numeral 7 denotes a seat cushion material. The seat cushion material 7 is made of cotton or non-woven fabric 16 and is packed in a bag-shaped outer cover 17 made of a soft material having excellent abrasion resistance and good feel. It becomes.

As shown in FIGS. 1 and 3, the backrest portion 2 has a backrest frame 19 having left and right plastic frame portions 18, 18 formed in a vertical arc along the body line. And a back cushion material 20 that covers the front side of the backrest frame 19.

The back cushion member 20, like the seat cushion member 7, is made of cotton, nonwoven fabric, or the like, and is packed in an exterior cover. The left and right sides and the back side of the backrest 2 are covered with an elastic cloth 21.

The single long guide rail 4 is composed of a square pipe bent in an arc shape over the entire length in the vertical direction so as to substantially extend along the arc-shaped backrest portion 2 and is substantially parallel to the back side of the backrest portion 2. Can be attached integrally.

The long guide rail 4 is formed to be longer than the entire length of the backrest 2 in the vertical direction, and the backrest is extended so that the lower portion 4a of the long guide rail 4 extends further below the lower end of the backrest 2. Attached to the back side of part 2,
At the time of attachment, as shown in FIG. 3, a locking piece 22 is fixed to the long guide rail 4 side, and a bracket 23 having a hat-shaped cross section is fixed to the backrest frame 18 with screws 24, and the bracket 23 is engaged with the bracket 23. The stop piece 22 is inserted and engaged.

As a result, the lower portion 4a extending further below the lower end of the backrest portion 2 of the long guide rail 4
Is located on the back side of the seat 1.

As shown in FIG. 3, a single self-propelled unitized massage mechanism 25 is provided on a single long guide rail 4.

The massage mechanism 25 includes a treatment element 3 such as a massage roller for massaging or tapping, a driving motor 26 for driving the treatment element 3, and the driving motor 26 or a driving motor different from the driving motor 26. Left and right driving sprockets 27 and three left and right idler wheels 2
8 are provided on a support base 29.

The massage mechanism 25 is provided between the three left and right idler wheels 28, 28 to extend the left and right long guide rails 4.
, And the teeth of the drive sprocket 27 are sequentially meshed with the drive holes 30 arranged at a predetermined pitch on the back side of the long guide rail 4 to reciprocate vertically along the long guide rail 4.

As shown in FIG. 1, the treatment element 3 has openings 3 provided between the left and right backrest frames 18, 18 in the up-down direction and the seat plate 6 and the seat frame 5 in the front-rear direction.
1, 32, cushion material 20, 7
It touches the human body from below.

Thus, as shown in FIGS. 1 and 4, the single long guide rail 4 is provided with left and right arms 33 in the vertical middle part thereof in an upright manner. By being pivotally attached to the left and right upright plates 12 with the shaft 34, it is supported on the base frame 9 so as to be tiltable in the front-rear direction around the shaft 34.

A reclining power unit 35 such as a hydraulic cylinder is stretched between the base frame 9 and a portion of the long guide rail 4 deviated from the shaft 34,
By the operation of the reclining power unit 35, the backrest 2 is rotated in the front-rear direction along with the long guide rail 4 in an upright posture (solid line state in FIG. 2) and a reclined posture (two-dot chain line state in FIG. 2). be able to.

The reclining power unit 35
Is operated by a reclining operation lever (not shown) provided below the armrest 8, for example.

In the upright posture of the backrest 2, the lower portion 4a of the long guide rail 4 that extends further below the lower end of the backrest 2 is located away from the rear surface of the seat 1 (see FIG. 3). When the backrest 2 is switched to the lying posture together with the long guide rail 4, the treatment element 3 is moved and guided almost parallel to the back side of the seat 1 near the front end of the seat 1. (Two-dot chain line in FIG. 2).

As shown in FIG. 2, the axis 34, which is the center of rotation of the reclining of the backrest 2, is set at substantially the same position as the position P which is the hip point of the user. This can reduce the displacement between the seat surface and the human body when the backrest portion 2 is reclined backward, that is, the displacement of the rotation axis of the backrest portion 2 and the human body can be reduced, and can eliminate the discomfort when reclining. it can.

When the backrest 2 is upright as shown in the solid line state in FIG. 2 and as shown in FIG. 5, the treatment element 3 is moved along the long guide rail 4 from near the upper end S1 of the backrest 2 to near the lower end S2. By moving it, it is possible to massage from the neck to the waist. When the backrest 2 is tilted backward (reclined) as shown by the two-dot chain line in FIG. 2 and as shown in FIG. 6, the treatment element 3 is moved along the long guide rail 4 from near the upper end S1 of the backrest 2 to the seat 1. By moving continuously from the front end to the vicinity S3, it is possible to massage from the neck muscles to the waist, buttocks and thighs.

The control for moving the treatment element 3 from near the upper end S1 of the backrest 2 to near the lower end S2 or near the front end S3 of the seat 1 is controlled by a control device (not shown).

For example, a moving position detecting switch (not shown) of the massage mechanism 25 is provided near the upper end, near the middle, and near the lower end of the long guide rail 4, and is automatically controlled by the detecting operation of the detecting switch.

As shown in FIG. 2, a footrest 36 is mounted on the front side of the seat 1 so as to be able to switch between a substantially horizontal posture and a drooping posture around an axis 37 so as to be freely movable.
If the footrest 36 is provided with a vibrator 38 and the like, and the footrest 36 is in a substantially horizontal position in front of the seat 1, the calf can be massaged by the vibrator 38 with the foot placed thereon. be able to.

The lower part 4a of the long guide rail 4
6 extends to a footrest 36 mounted horizontally on the front side of the seat 1 as shown by a two-dot chain line A in FIG. 6, and is placed on the footrest 36 with the treatment element 3 on the long guide rail 4. Massage up to the calf can be possible.

In this case, the vibrator 3 is
It is not necessary to provide the backrest 2 and the opening 3 of the seat 1.
Similarly to the first and second embodiments, the footrest 36 may be provided with an opening for allowing the treatment element 3 to face.

The size may be set such that the calf can be placed when sitting down with the knees extended thereon, and the attachment of the footrest portion 36 in FIG. 5 may be omitted.

According to this, as shown by the two-dot chain line in FIG. 7, the backrest portion 2 is tilted backward, and the single treatment element 3 is moved along the long guide rail 4, so that the neck, the waist, and the buttocks are moved. The whole body can be massaged up to the thighs and calves.

In each of the embodiments described above, the backrest 2 is disposed so as to be reclined with respect to the seat 1, and the long guide rail 4 is integrally connected to the backrest 2. Both can be tilted, and when the backrest 2 is reclined, the lower part 4a of the long guide rail 4 is arranged so as to be substantially parallel to the back side of the seat 1 but is not limited to this. Not something.

As shown in FIG. 8, the seat portion 1 and the backrest portion 2 are integrally formed at a predetermined angle, and a footrest portion 36 is provided on the front side of the seat portion 1. By extending the lower portion 4a to the footrest portion 36, the entire portion can be formed in an arc shape so as to closely follow the backrest portion 2, the seat portion 1, and the footrest portion 36.

In this case, the foot rest 36 is also attached to the backrest 2.
Similarly to the openings 31 and 32 of the seat 1 and the openings 1, 32, openings for allowing the treatment element 3 to face are provided. According to this, with a single long guide rail 4 and a treatment element 3, from the neck to the waist, buttocks,
You can massage your whole body up to your thighs and calves.
