ABSTRACT:
There is disclosed a vehicle seat provided with a system for facilitating relieving of fatigue of a person driving a vehicle, the vehicle seat comprising a seat back (1) having a pad (5), the system including an occupant's body-motion promoting mechanism (12) provided in the seat back so as to be arranged behind the pad for locally pressing an occupant's body during driving of the vehicle and releasing the occupant's body from pressure, thereby moving the occupant's body and promoting blood circulation of the person. The occupant's body-motion promoting mechanism is configured to intermittently perform repeated pressing/releasing operations with respect to the third lumbar vertebrae of the occupant in a range of three to seven times, at a stroke amount in a range of 10 mm to 20 mm, and at a time interval of 5 minutes to 10 minutes.
