The first locking portion 104 and the second locking portion 106 are movable in the radial direction of the rotating member 96 and are urged radially inward by the urging member (not shown). ing.

  On the other hand, a plurality of locked portions 108 that are locked to the first locking portion 104 and the second locking portion 106 are formed on the outer peripheral portion of the rotating member 96. The locked portion 108 is formed with an inclined surface 108A that goes inward in the radial direction of the rotating member 96 in the R7 direction.

  In the energy storage unit 92, the second locking portion 106 is connected to a release lever 110 provided on the grip 20 shown in FIG. 13 via a wire or the like (not shown). When the release lever 110 is pulled, the second locking portion 106 is moved radially outward of the rotating member 96, and the locking state between the second locking portion 106 and the locked portion 108 is released. It is configured.

  Furthermore, in this vehicle seat apparatus S8, as shown in FIG. 13, between the stimulus applying part 24 and the turning member 96, the turning motion of the turning member 96 is applied to the occupant support surface of the stimulus applying part 24. An actuating portion 112 is provided for conversion into a reciprocating motion in the contact / separation direction relative to 12A.

  The operating unit 112 includes a swing arm 114 and a connecting arm 116. The swinging arm 114 is integrally fixed to one end side in the longitudinal direction, and the one end side in the longitudinal direction of the transmission arm 22 can be rotated via the rotation shaft 118 on the other end side in the longitudinal direction. It is connected to.

  On the other hand, one end side in the longitudinal direction of the connecting arm 116 is rotatably connected to the intermediate portion in the longitudinal direction of the swing arm 114 via the rotation shaft 120, and the other end side in the longitudinal direction is connected to the rotating member 96. A portion that is radially outward of the moving shaft 94 is rotatably connected via a rotating shaft 122.

  In the vehicle seat apparatus S8, the string reaction spring 98 constitutes the operation reaction force acting portion in the present invention, and the first locking portion 104, the second locking portion 106, the locked portion 108, and the release. The lever 110 constitutes a switching unit in the present invention.

  In the vehicle seat device S8, as described above, when the transmission arm 22 is rotated in the R7 direction, the transmission arm 22 is in a state where the first locking portion 104 is locked with the locked portion 108. And the rotation member 96 is rotated in the R7 direction. On the other hand, when the transmission arm 22 is rotated in the R8 direction, the second locking portion 106 and the locked portion 108 are locked, thereby preventing the rotation member 96 from rotating in the R8 direction. . Accordingly, the transmission arm 22 is repeatedly reciprocated in the directions of R7 and R8, whereby the string winding spring 98 is wound, whereby elastic energy is stored in the string winding spring 98 (energy storage state in the present invention).

  On the other hand, when the release lever 110 is pulled and the locked state between the second locking portion 106 and the locked portion 108 is released, the string winding spring 98 is restored, and the elastic energy (biasing force) released by the string winding spring 98 is restored. ) Rotates the rotating member 96 in the R8 direction (energy released state in the present invention).

  When the rotating member 96 is rotated in the R7 direction, the second locking portion 106 passes over the locked portion 108 by passing through the inclined surface 108A. Similarly, when the rotation member 96 is rotated in the R8 direction, the first locking portion 104 gets over the locked portion 108 by passing through the inclined surface 108A.

  When the rotating member 96 is rotated by the biasing force of the string spring 98 as described above, the rotating motion of the rotating member 96 is supported by the connecting arm 116 and the swing arm 114 to support the occupant of the stimulus applying unit 24. It is converted into a reciprocating motion in the contact / separation direction with respect to the surface 12A. As a result, the occupant sitting on the vehicle seat 16 is continuously stimulated.

  Further, when the grip 20 is moved in the vertical direction (R7, R8 direction), the transmission arm 22 is rotated in the R7, R8 directions around the rotation shaft 94. As a result, the stimulus applying unit 24 is reciprocated in the vertical direction of the seat back 12 together with the swing arm 114, and the stimulus is given to the occupant seated on the vehicle seat 16.

  Thus, according to the vehicle seat apparatus S8, when an operating force is input to the grip 20, elastic energy can be temporarily stored in the string spring 98. Further, by releasing the elastic energy accumulated in the string spring 98, the stimulus applying part 24 can be displaced, and a stimulus can be given to the occupant seated on the vehicle seat 16.

  Further, according to the vehicle seat device S8, the release lever 110 can switch between a state in which elastic energy is accumulated in the string winding spring 98 and a state in which elastic energy is released from the string winding spring 98 at an arbitrary timing. Thereby, the operativity at the time of giving a passenger | crew a stimulus can be made favorable.

  Furthermore, according to the vehicle seat device S8, the occupant can be continuously stimulated by the operating portion 112, so that the massage effect for the occupant can be further improved.

  Further, according to the vehicle seat device S <b> 8, when an operation force is input to the grip 20 in the seat vertical direction, an operation reaction force is applied to the grip 20 by the string spring 98. Therefore, for example, an occupant (operator) seated on a rear seat with respect to the vehicle seat 16 can input an operation force to the grip 20 by hand to perform a hand exercise (for example, a muscular strength enhancement exercise). .

  The vehicle seat device S8 can be combined with the above-described configuration of the vehicle seat devices S2 to S7 according to the second to seventh embodiments (for example, the above-described stimulation limiting unit 42, universal joint 52, The movable support portion 56, the slide rail 66, the pedal 76, etc.) may be appropriately combined.

  In the vehicle seat device S8, the elastic energy stored in the string spring 98 may be used for other purposes (for example, assistance when the passenger gets on and off). good.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited above, Of course, it can change and implement variously within the range which does not deviate from the main point. .

  In each of the above embodiments, the vehicle seat devices S1 to S8 are provided on the front seat of the vehicle. For example, the second row of the seats arranged in three rows in the front-rear direction of the vehicle. Etc. may be provided.

  In the above embodiments, the vehicle seat devices S1 to S8 are applied to a vehicle such as a passenger car. However, the vehicle seat devices S1 to S8 may be applied to a bus or the like. It may be applied to other vehicles.
