Vehicle seat with system for facilitating relieving of fatigue of person sitting on the seat
First Claim
1. A vehicle seat provided with a system for facilitating relieving of fatigue of an occupant sitting on the vehicle seat, the vehicle seat including a seat back;
- the system comprising;
an occupant'"'"'s body-motion promoting means provided in an interior of the seat back for repeatedly locally pressing the occupant on the vehicle seat, to thereby promote blood circulation of the occupant;
a lateral acceleration sensor provided in the interior of the seat back for detecting accelerations that are applied in right and left lateral directions relative to a vehicle; and
an acceleration-distinction control circuit provided in the interior of the seat back for causing the body-motion promoting means to be maintained in a drivable state when an acceleration detected by the lateral acceleration sensor is in a predetermined value range, for causing drive of the body-motion promoting means to be once stopped when the lateral acceleration becomes an excessive value exceeding an upper limit of the predetermined value range during the drive of the body-motion promoting means, and for returning the body-motion promoting means to the drivable state when the lateral acceleration drops toward the predetermined value range from the excessive value.

Abstract
There is disclosed a vehicle seat provided with a system for facilitating relieving of fatigue of an occupant on the vehicle seat, the vehicle seat including a seat back, the system comprising an occupant'"'"'s body-motion promoting means 6 provided in an interior of the seat back 1 for repeatedly locally pressing the occupant on the vehicle seat, to thereby promote blood circulation of the occupant, a lateral acceleration sensor 8 provided in the interior of the seat back 1 for detecting accelerations that are applied in right and left lateral directions relative to a vehicle, and an acceleration-distinction control circuit provided in the interior of the seat back 1 for causing the body-motion promoting means 6 to be maintained in a drivable state according when an acceleration detected by the lateral acceleration sensor 8 is in a predetermined value range, for causing drive of the body-motion promoting means to be once stopped when the lateral acceleration becomes an excessive value exceeding an upper limit of the predetermined value range during the drive of the body-motion promoting means, and for returning the body-motion promoting means to the drivable state when the lateral acceleration drops toward the predetermined value range from the excessive value.
