A psychosomatic state adjustment support device includes: a storage section that stores a target psychosomatic state for each destination of a moving body; a specification section that specifies a current psychosomatic state of an occupant of the moving body; an acquisition section that acquires a destination of the moving body; a deciding section that decides a vibration pattern based on the target psychosomatic state according to the destination and the current psychosomatic state; and a control section that applies a vibration stimulation to the occupant by causing a vibration applying section provided in a seat on which the occupant is seated to vibrate based on the vibration pattern.

A car seat includes an air outlet located in a seat upper portion (a portion provided above a seat cushion and including a seat back and a headrest) to let out air therethrough; an air inlet located in the seat upper portion to draw in air therethrough; at least one fan configured to produce a current of air flowing from the air outlet toward the air inlet at a front side of the seat upper portion; and a scenting device configured to scent air to be forced out through the air outlet. The air outlet and the air inlet are located in such positions that at least part of the headrest is positioned between the air outlet and the air inlet in a direction from the air outlet toward the air inlet as viewed from a front side.

A utility vehicle includes a chassis and a work implement movably coupled to the chassis. An operator support is positioned within an operator cab. The operator support includes a seat and a backrest coupled to the seat. A position of the operator support is selectively adjustable relative to the chassis. The utility vehicle further includes a control system in communication with the operator support. The control system includes a sensor operable to sense a position of the work implement relative to the chassis, and a controller including a processor and a memory. The controller is configured to receive a signal from the sensor representative of the position of the work implement. The controller is further configured to generate a signal to automatically adjust the position of the operator support relative to the chassis based in part on the position of the work implement relative to the chassis.

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.

A ventilation assembly comprises a number of fan systems configured to purify air and a number of air distribution assemblies. Each air distribution assembly of the number of air distribution assemblies is configured to be removably installed on a seatback of a passenger seat. Each air distribution assembly of the number of air distribution assemblies comprises a pair of air distribution vents, ductwork configured to receive air from at least one fan system of the number of fan systems and direct air to the pair of air distribution vents, and a seat attachment device configured to removably couple the pair of air distribution vents to the seatback such that each air distribution vent is situated on opposite sides of the seatback for providing purified air to a seated passenger.

An artificial muscle chair device includes a plurality of artificial muscles embedded in a chair. Each artificial muscle includes a housing having an electrode region and an expandable fluid region. A first electrode and a second electrode each disposed in the electrode region of the housing. The artificial muscle chair device further includes a dielectric fluid disposed within the housing. The first and second electrodes electrostatically attract, inflating the expandable fluid region with dielectric fluid and thereby applying selective pressure to an outer surface of the chair.

A car seat includes an actuator capable of changing an orientation of a rest surface of a seat back laterally by turning and moving at least a side portion frame that is part of the car seat frontward and rearward, and a controller configured to exercise control over the actuator. The controller includes a run-time posture support unit configured to execute a run-time posture support control under which when a car makes a turn, the actuator is regulated to cause the rest surface of the seat back to be oriented in a direction of the turn. The run-time posture support unit is configured to regulate the actuator in accordance with a placement of the seat in the car, when the run-time posture support unit executes the run-time posture support control.
