A seat assembly includes first and second bladders and a controller. The first bladder has a sensor configured to detect a pressure of the first bladder. The controller is configured to inflate the first bladder to a target pressure, as detected by the sensor, and to inflate the second bladder based on time expended for the first bladder to be inflated to the target pressure.

A defibrillation system may include a cardiac arrest detector detecting whether cardiac arrest of a passenger has occurred in a state of taking a seat of a self-driving vehicle and fastening a seatbelt of the vehicle; a passenger posture detection device detecting a posture of the passenger; a seat driving device changing the posture of the passenger into another posture in which the passenger lies down based on a detection signal of the passenger posture detection device when the cardiac arrest of the passenger occurs; a heart position detector configured to search for a position of a heart of the passenger; a defibrillation robot to perform a CPR method or a method using an AED on the heart of the passenger; and a controller controlling operation of the seat driving device, the heart position detector, and the defibrillation robot based on detection signals of the cardiac arrest detector and the passenger posture detection device.

A device for physiotherapy includes at least a seating surface and a back rest. The back rest is provided with arm holders positionable under a person's underarms. The back rest is also provided with powered apparatus to move the arm holders in a direction away from the seating surface, thereby to lift a person off the seating surface, and to return the person to the seating surface.

A human body stimulation device and a human body stimulation method using the human body stimulation device. A human body stimulation device includes a human body stimulation unit including a sonic vibration module configured to apply sonic vibration to a body of the user, at least one motor configured to move the sonic vibration module, a position detection unit configured to detect a position of the sonic vibration module, and a controller. The controller determines a body part corresponding to the detected position of the sonic vibration module and controls the sonic vibration module to output the sonic vibration based on characteristics of the body part.

A chair-type massage machine includes a main body on which a person to be treated is to be seated, a holding part at least part of which is placed inside a container recess to hold a first operation unit, and a moving mechanism for moving the holding part. The holding part is reciprocatably moved between a first position in which the first operation unit is contained in the container recess and a second position in which the first operation unit is exposed. The chair-type massage machine further includes a second operation unit for moving the holding part.

Therapeutic cushions having a plurality of inflatable columnar cells, pumping mechanism, and a manifold or valve system for moving a fluid between the pumping mechanism and the inflatable columnar cells. The inflatable columnar cells are constructed such that inflation and deflation of the cells cause vertical expansion/contraction of the cells with limited lateral expansion/contraction. The manifold or the valve system connect the pumping mechanism with the inflatable columnar cells such that a plurality of zones are created. A valve assembly can include a plurality of valves and is adjustable among at least three valve configurations to vary fluid connections to the inflatable columnar cells to produce rearwardly advancing waves. A venting manifold may vent air from the cells between the cushions.

A seat includes a seat bottom and a seat back. At least one of the seat bottom and the seat back includes a trim cover having a seating surface and a plurality of individually-controllable massage elements underlying the trim cover. Each of the plurality of individually-controllable massage elements has a surface facing the trim cover, wherein at least a portion of the surface includes a heating layer selectively configured to generate heat.

A spa system having a chair attachment and a tabletop device. The chair attachment includes a receptacle which is removably attachable to a chair which has a motor for providing bubble treatments. The receptable includes a housing attachment having water jets to provide a spa treatment to a user. Further, the receptacle allows for a user to submerge their entire hand within water located in the receptacle. Additionally, the tabletop device is mounted onto a table to then aid in providing spa treatment for a user. Each device contains a compartment that is attachable to the side of the device which contains various utensils to aid a user in a manicure.

A method includes disposing a plurality of actuators about a subject, each actuator being configured to generate a respective vibration signal, each vibration signal applying a normal force to the subject, and controlling the plurality of actuators such that the respective vibration signal of each actuator of the plurality has a respective vibration characteristic. Each actuator is oriented such that the respective vibration signal propagates along a longitudinal axis of the subject for stimulation of the subject remote from the plurality of actuators.

A massage system for a seat having a seat surface. At least one plane is defined for the seat, which plane is spanned by a longitudinal axis and a vertical axis of the seat. The at least one plane separates a first side and a second side of the seat from one another and intersects the seat. At least one massage element is arranged in at least one component of the seat. The at least one massage element has at least one active surface which is arranged on at least one of the two sides of the seat. The at least one active surface of the at least one massage element executes at least one stroke movement which is oriented parallel, downwards, and/or upwards at least partially in the direction of the at least one plane, relative to the seat surface
