摘要： A vehicle seat provided with a seat cushion and a seat back, wherein the seat back is provided with: a urethane pad in which the surface is covered by a trim cover; and a pressure means in which a laterally extending shaft and a pair of pressing parts in the vertical direction relative to the shaft are formed on the reverse side of the urethane pad toward the side covered by the trim cover, and a configuration is adopted such that the shaft extending in the lateral direction of the pressure means rotates or swings, thereby causing the upper-side pressing part among the upper and lower pair of pressing parts to press the upper side of the urethane pad forward and the lower-side pressing part to press the lower side of the urethane pad forward.

摘要： A vehicle seat includes: a chamber in which at least a seat-front-surface side is covered with a pad and which circulates the air blown from a front surface of a seat through the pad; a fan configured to send air into the chamber; and a support body which supports the chamber so as to be able to sink in an acting direction of a load applied to the surface of the seat. The chamber includes a first region and a second region, and the first region and the second region are configured to allow subduction of the chamber independently of each other.

摘要： To provide a technique that enables the reduction of fatigue of a vehicle occupant at low cost and without an increase in the number of parts. Without preparing a sensor in addition to a posture changing mechanism, the position of a lumbar vertebra or thoracic vertebra of each vehicle occupant is estimated by controlling the operation of the posture changing mechanism. The posture changing mechanism includes: a back side support mechanism; a first motor capable of shifting a position of the back side support mechanism with respect to a vertical direction; and a second motor capable of shifting the position of the back side support member with respect to a front-back direction. A position of a lumbar vertebra of the vehicle occupant is estimated by: while changing the vertical position of the back side support mechanism by means of the first motor, changing a forward position of the back side support mechanism at each of the different vertical positions thereof by means of the second motor so as to obtain a turnover number value of the second motor achieving a desired resistance; and comparing the turnover number values of the second motor achieving the desired resistance. A position of the thoracic vertebra is determined by calculation based on the position of the lumbar vertebra. The position of the posture changing mechanism is set based on the results of estimation of the individual positions. Thus, a fatigue reduction effect is provided on the vehicle occupant by utilizing the posture changing mechanism.
