  FIG. 10 is a perspective view illustrating a state in which the shielding device 1 is attached to both sides of the vehicle seat 10. In FIG. 10, the vertical direction, the horizontal direction, and the front-back direction are defined for convenience of explanation.

  A vehicle seat 10 shown in FIG. 10 includes a seat portion 10a, a backrest portion 10b, and an armrest portion 10c. A laterally extending plate 10e is attached to the side portion 10d of the backrest portion 10b, and a laterally extending shaft 10f is attached to a position ahead of the plate 10e. In the present embodiment, the length of the protruding portion 2f of the bone portion 2a is longer than the distance between the plate 10e and the shaft 10f. The shielding device 1 is attached to the side portion 10d of the backrest portion 10b by connecting the shaft 10f and the shaft portion 3 to each other. Even when the seated person releases his / her hand from the bone part 2d (protruding part 2h) after deployment of the shielding member 4 when the shielding device 1 is attached, the bone parts (2a, 2b, 2c, 2d) and the shielding member 4 are deadweight. The tightness degree (contact resistance) between the bone parts (2a, 2b, 2c, 2d) is adjusted by adjusting the tightening degree of the shaft part 3 so as not to be lowered.

  When using the shielding device 1, the seated person grasps the protruding portion 2h of the bone portion 2d and lifts it upward. Since the bone parts (2a, 2b, 2c, 2d) are connected to each other via the shielding member 4, when the bone part 2d is lifted, the other bone parts (2a, 2b, 2c) are also connected to the bone part 2d. There is a possibility that each bone part (2a, 2b, 2c, 2d) does not spread. However, as described above, the length of the protruding portion 2f of the bone portion 2a is longer than the distance between the plate 10e and the shaft 10f, and therefore the protruding portion 2f contacts the plate 10e when the bone portion 2a is slightly rotated. Touch. Therefore, the bone part 2a cannot be rotated any more. In this state, when the seated person further lifts the bone part 2d upward, the bone parts (2b, 2c, 2d) are rotated and spread, and the shielding member 4 is developed accordingly. As described above, in the present embodiment, the protruding portion 2f of the bone portion 2a abuts on the plate 10e and functions as a stopper, so that when the bone portion 2d is lifted, the other bone portions (2a, 2b, 2c). Is prevented from co-rotating with the bone portion 2d, so that each bone portion (2a, 2b, 2c, 2d) can be reliably expanded.

  When the shielding member 4 is deployed, the side surface of the seated person's head is obscured by the deployed shielding member 4. Thus, the seated persons sitting on the seats adjacent to each other with the shielding device 1 interposed therebetween do not look at each other, and the privacy of the seated persons is maintained. The two shielding devices 1 attached to both side portions 10d of the vehicle seat 10 can be independently operated.

  The shielding device 1 may be configured not to be lifted from the bottom to the top but to be lowered from the top to the bottom. The deployment angle of the shielding member 4 (deployment angle between the bone portion 2a and the bone portion 2d) can be arbitrarily designed such as 90 degrees or 180 degrees.
