The operation of the rotation mechanism 23 will be described with reference to FIGS.
The rotation mechanism 23 includes a regulation mechanism 23 </ b> A that regulates the rotation of the second armrest portion 22 when the second armrest portion 22 rotates to the position farthest from the first armrest portion 21. The rotation mechanism 23 includes a state in which the second armrest portion 22 is allowed to rotate with respect to the first armrest portion 21 shown in FIG. 8 and a state in which rotation relative to the first armrest portion 21 shown in FIG. 9 is restricted. Change between.

  As shown in FIG. 8, when the massage of the arm 100 is not performed, the second armrest portion 22 rotates to a position closest to the first armrest portion 21 with the front end side as a base point via the rotation mechanism 23. At this time, the arm arrangement space 20A between the first armrest portion 21 and the second armrest portion 22 is minimized. When the second armrest portion 22 rotates to the position closest to the first armrest portion 21, the airbag 30 disposed in the first armrest portion 21 and the first armrest portion 21, the second armrest portion 22 and the second armrest portion. The second armrest portion 22 does not further rotate downward due to contact with the airbag 30 disposed at the position 22. Further, the second armrest portion 22 does not rotate upward due to the weight of the second armrest portion 22 and the airbag 30 disposed on the second armrest portion 22. On the other hand, when the user lifts the rear end side of the second armrest portion 22, the second armrest portion 22 rotates upward.

  The second air bag 50 and the fourth air bag 70 are arranged alternately so that substantially the whole does not overlap in the longitudinal direction of the armrest 20. For this reason, when the 2nd armrest part 22 approaches the 1st armrest part 21, the armrest 20 can be accommodated compactly in the height direction.

  As shown in FIG. 9, when performing massage of the arm 100, the second armrest portion 22 rotates to a position farthest from the first armrest portion 21 with the front end side as a base point via the rotation mechanism 23. At this time, the arm arrangement space 20A between the first armrest portion 21 and the second armrest portion 22 is maximized. When the second armrest portion 22 rotates to the position farthest from the first armrest portion 21, the restriction mechanism 23 </ b> A restricts further rotation of the second armrest portion 22 upward and downward.

  With reference to FIG. 10, the relationship between the arm 100 and the second airbag 50 when the arm 100 is arranged in the arm arrangement space 20 </ b> A will be described. Note that an arm 100 indicated by a two-dot chain line in FIG. 10 indicates an arm 100 shorter than the arm 100 indicated by a broken line.

  The stimulation part rows 54A and 54B of the second airbag 50 are along the longitudinal direction of the arm 100 indicated by a two-dot chain line in FIG. When the fingertips of the arms 100 are arranged so as to be aligned with the front ends of the armrests 20, the first stimulating section row 54A stimulates the arms 100 and the inside of the wrist and the base of the thumb. The second stimulation part row 54B stimulates the outside of the arm and wrist and the base part of the little finger.

  Compared to the long arm 100 indicated by the two-dot chain line, the elbow side of the arm 100 is more likely to be closer to the seat 11 side in the short arm 100 indicated by the broken line. Since the second stimulation part row 54B is formed from the outside toward the seat part 11 (see FIG. 1) as it goes from the front end side to the rear end side, as shown by the broken line in FIG. In addition, the stimulation part rows 54 </ b> A and 54 </ b> B of the second airbag 50 can extend along the arm 100.

The operation of the airbag 30 will be described.
As shown in FIG. 11, when air is supplied to the first airbag 40 and the third airbag 60 and air is discharged from the second airbag 50 and the fourth airbag 70, the first airbag 40 and The third airbag 60 is inflated, and the second airbag 50 and the fourth airbag 70 are contracted.

  As shown in FIG. 12, when air is supplied to the first airbag 40 and the third airbag 60 and air is supplied to the second airbag 50 and the fourth airbag 70, the first airbag 40, The third airbag 60, the second airbag 50, and the fourth airbag 70 are inflated.

  As shown in FIG. 13, when air is discharged from the first airbag 40 and the third airbag 60 and air is supplied to the second airbag 50 and the fourth airbag 70, the first airbag 40 and The third airbag 60 contracts, and the second airbag 50 and the fourth airbag 70 expand.

  The force that prevents the arm 100 from moving relative to the armrest 20 when the first airbag 40 and the third airbag 60 are most inflated (hereinafter referred to as “restraint force A”) is that the second airbag 50 and the fourth airbag 70 It is larger than the restraining force A when it expands most.

  Specifically, the restraining force A is a dimensional difference in the direction toward the arm 100 between the time when each of the airbags 40 to 70 is most inflated and the time when each of the airbags 40 to 70 is contracted most (hereinafter, “Inflated amount”) and an area facing the arm 100 of each of the airbags 40 to 70 (hereinafter referred to as “opposing area”). The restraining force A increases as the expansion amount increases, and increases as the facing area increases.

The sum of the inflation amount of the first airbag 40 and the inflation amount of the third airbag 60 is larger than the sum of the inflation amount of the second airbag 50 and the inflation amount of the fourth airbag 70.
The sum of the opposing area of the first airbag 40 and the opposing area of the third airbag 60 is larger than the sum of the opposing area of the second airbag 50 and the opposing area of the fourth airbag 70.

The binding force A is defined as follows according to the state of the airbag 30.
(A1) The restraint force A when the first airbag 40, the third airbag 60, the second airbag 50, and the fourth airbag 70 are all inflated is defined as a restraint force A1.
(A2) The restraining force A2 when the first airbag 40 and the third airbag 60 are most inflated and the second airbag 50 and the fourth airbag 70 are most contracted is defined as a restraining force A2.
(A3) The restraining force A when the first airbag 40 and the third airbag 60 are most contracted and the second airbag 50 and the fourth airbag 70 are most inflated is defined as a restraining force A3.
(A4) The restraining force A when the first airbag 40, the third airbag 60, the second airbag 50, and the fourth airbag 70 are all contracted is defined as a restraining force A4.

  In the restraining forces A1 to A4, a relationship of “restraining force A1> binding force A2> binding force A3> binding force A4” is established. When the restraint force A is equal to or greater than the restraint force A2, the arm 100 is blocked by a strong force that moves relative to the armrest 20. On the other hand, when the restraining force A is equal to or less than the restraining force A3, the arm 100 can easily move with respect to the armrest 20. The restraining force A between the restraining force A2 and the restraining force A3 corresponds to the “predetermined value of the restraining force”.

  With reference to FIGS. 14 and 15, the operation of the stimulation unit 54 will be described. 14 and 15 indicate the state of the second airbag 50 when no air is supplied from the second airbag 50 and no pressure is applied to the second airbag 50 from the outside. Show.

  As shown in FIG. 14, when the second airbag 50 is inflated most, the stimulation part 54 protrudes upward from the outer peripheral part 55. Therefore, the stimulation of the stimulation unit 54 acts on the arm 100 more strongly than the outer peripheral portion 55 on the arm 100.

  As shown in FIG. 15, when the second airbag 50 contracts most, the stimulation part 54 is recessed by contact with the arm 100, and the positions of the outer peripheral part 55 and the upper end part of the stimulation part 54 are equal. For this reason, both the outer peripheral portion 55 and the stimulation portion 54 stimulate the arm 100 strongly on the arm 100.

The relationship between the first airbag 40 and the second airbag 50 will be described.
As shown in FIG. 16, since the first airbag 40 has a flat surface, when the first airbag 40 is inflated, the center portion in the width direction and the center portion in the longitudinal direction are the largest.

  When the first airbag 40 is inflated, the stimulating portion 54 of the first stimulating portion row 54A and the stimulating portion 54 of the second stimulating portion row 54B are overlapped with portions of the first airbag 40 having different inflating amounts. It has been. For this reason, the stimulation part 54 of the 2nd stimulation part row | line | column 54B is located above the stimulation part 54 of 54 A of 1st stimulation part rows | lines. That is, the contact pressure that is the strength of stimulation to the arm 100 of the stimulation unit 54 in the second stimulation unit row 54B is larger than the contact pressure to the arm 100 of the stimulation unit 54 in the first stimulation unit row 54A. In this case, the stimulation unit 54 in the first stimulation unit row 54A corresponds to a “first stimulation unit”. The stimulation unit 54 in the second stimulation unit row 54B corresponds to a “second stimulation unit”.

  Further, when the first airbag 40 is inflated, the respective stimulating portions 54 in the respective stimulating portion rows 54A and 54B are overlapped with portions of the first airbag 40 having different expansion amounts. For this reason, the stimulation part 54 arrange | positioned near the center in the longitudinal direction of the 1st airbag 40 is located above the stimulation part 54 arrange | positioned at the edge part of the longitudinal direction of the 1st airbag 40. FIG. That is, the contact pressure to the arm 100 of the stimulation unit 54 disposed near the center in the longitudinal direction of the first airbag 40 is such that the arm 100 of the stimulation unit 54 disposed at the longitudinal end of the first airbag 40. It becomes larger than the contact pressure. In this case, the stimulation unit 54 disposed near the center in the longitudinal direction of the first airbag 40 corresponds to a “first stimulation unit”. The stimulation part 54 arranged at the end of the first airbag 40 in the longitudinal direction corresponds to a “second stimulation part”.

  As shown in FIG. 17, when the first airbag 40 is contracted, the height positions of the stimulation part 54 in the first stimulation part row 54A and the stimulation part 54 in the second stimulation part row 54B are substantially equal. Become. That is, the contact pressure to the arm 100 of the stimulation part 54 in the first stimulation part row 54A is substantially equal to the contact pressure to the arm 100 of the stimulation part 54 in the second stimulation part row 54B.

  When the first airbag 40 is inflated and contracted, the relationship between the height positions of the stimulating portion 54 and the second stimulating portion row 54B in the first stimulating portion row 54A is different. Therefore, different stimuli can be applied to the arm 100 when the first airbag 40 is inflated and when it is contracted.

With reference to FIG. 18, an example of the massage operation by the airbag 30 will be described.
At time t <b> 11, that is, when the user performs an operation of performing massage with the remote controller 91, the supply device 80 switches the electromagnetic valve 82 and supplies and discharges air according to “state A”.

Further, the second airbag 50 and the fourth airbag 70 are arranged so as not to overlap when the second airbag 50 and the fourth airbag 70 face each other. For this reason, an armrest can be accommodated compactly.

  (11) The first airbag 40 overlaps the second airbag 50 in the direction from the first armrest portion 21 toward the second armrest portion 22. The third airbag 60 overlaps the fourth airbag 70 in the direction from the second armrest portion 22 toward the first armrest portion 21.

  Therefore, when only the first airbag 40 and the third airbag 60 are inflated, and when the first airbag 40, the second airbag 50, the third airbag 60, and the fourth airbag 70 are inflated. Different massages can be performed on the same part of the user's arm 100 when only the second airbag 50 and the fourth airbag 70 are inflated.
