It is formed so that it can be flexibly deformed.

As shown in FIG. 5, the vibration generating unit 6 mainly includes a motor 61, an eccentric weight 62, and a mounting bracket 63. Vibration is generated by driving the motor 61 to rotate the eccentric weight 62. Is configured.

The eccentric weight 62 is a weight formed in a substantially fan shape, and is fixed to the rotating shaft 61A of the motor 61 in the vicinity of a main part of the fan. The eccentric weight 62 is mainly composed of a plate-shaped weight unit 62A. In the present embodiment, a plurality of weight units 62A can be stacked in the axial direction (horizontal direction) of the motor 61, and a screw 64 is further provided. They can be fixed and separated from each other. As a result, the weight of the eccentric weight 62 can be easily changed by changing the number of the weight units 62A. Therefore, the vibration generating unit 6 can be changed according to the size of the vehicle seat S in which the vibration generating unit 6 is used. It is possible to easily change the magnitude of the vibration generated in.

The mounting bracket 63 is a substantially L-shaped plate-shaped member formed of metal, resin, or the like, and is disposed between the main body portion 61B of the motor 61 and the eccentric weight 62 so that the motor 61 can be mounted by screws (not shown). It mainly has a fixed portion 63A to be fixed and a mounting portion 63B extending from the front end portion of the fixed portion 63A toward the main body portion 61B. The mounting portion 63B has a long plate shape that is long in the up-down direction orthogonal to the axial direction of the motor 61, and one through hole 63C is formed at both ends in the longitudinal direction (only one is shown).

In the vibration generating unit 6, the through hole 63C of the mounting bracket 63 is passed through the through hole 63C of the mounting bracket 63 through the bolt B5 provided by being insert-molded in the pressure receiving member 40 or being passed through the through hole formed in the pressure receiving member 40 from the front side.

Next, the effect of the vehicle seat S configured as above will be described.
As shown in FIG. 4, in the vehicle seat S, the pressure receiving member 40 has the pressure receiving portion 41 and the left and right supporting portions 42, so that the central pressure receiving portion 41 and the left and right supporting portions 42 prevent the occupant's upper portion from increasing. The body can be supported in a wide range, and thus the upper body of the occupant can be stably supported. Further, as shown by the chain line in FIG. 4, since the vibration generating unit 6 is arranged at a position avoiding the tip end 42A which is most moved by the deformation of the supporting part 42, the vibration generating unit 6 causes the vibration of the supporting part 42. It is possible to prevent the deformation from being restricted. Further, since the vibration generating unit 6 is arranged at a position avoiding the tip 42A of the supporting portion 42 that moves most, it is possible to suppress the damping of the vibration generated in the vibration generating unit 6. It can be efficiently transmitted to passengers.

Further, in the present embodiment, since the vibration generating unit 6 is attached to the pressure receiving portion 41, the supporting portion 42 and the vibration generating unit 6 can be arranged separately, so that the deformation of the supporting portion 42 is restricted by the vibration generating unit 6. Can be further suppressed. Further, since the vibration generating unit 6 is attached to the pressure receiving portion 41 that is less likely to be deformed than the supporting portion 42, the vibration generated in the vibration generating unit 6 can be further suppressed from being damped, so that the vibration can be generated more efficiently. Can be communicated to the crew.

Further, in the present embodiment, since the vibration generating unit 6 is attached to the lower end portion of the pressure receiving portion 41 near the portion where the upper body of the occupant mainly contacts the seat back S2 during normal seating, the vibration generating unit 6 is generated. The vibration generated in the unit 6 can be more efficiently transmitted to the occupant. Further, since the vibration generating unit 6 is attached to the lower end portion of the pressure receiving portion 41, the pressure receiving member 40 can be greatly vibrated by the vibration generated by the vibration generating unit 6, so that the large vibration is transmitted to the occupant. It is possible to enhance the massage effect and the awakening effect.

Further, in the present embodiment, since the vibration generating unit 6 is attached to the rear surface 41R of the pressure receiving portion 41, the vibration generating unit 6 can prevent the occupant from feeling a sense of discomfort (hit). Further, the vibration generating unit 6 is less likely to get in the way in the seat back S2 as compared with the configuration in which the vibration generating unit 6 is attached to the front side of the pressure receiving portion 41, so that the size of the vehicle seat S is large as necessary. A relatively large vibration generating unit capable of generating a large vibration can be adopted.
