The invention relates to a vehicle seat comprising at least one seat element in which at least one heating device and at least one ventilation device are provided. The vehicle seat comprises a sensor device, which has at least one temperature sensor and at least one moisture sensor. A closed-loop/open-loop control device controls the heating device and/or the ventilation device in an open-loop or closed-loop manner on the basis of the data from the sensor device with respect to the comfort parameters of temperature and/or moisture content, whereby the seat climate can be actively controlled in an open-loop or closed-loop manner.

A vehicle with a flat seat may include a floor portion having a leg groove recessed downward from a surface of the floor portion; a seatback disposed on the floor portion and reclining by a rotation of the lower end; a seat cushion disposed on the floor portion ahead of the seatback; and a leg cushion disposed in the leg groove of the floor portion and having a rear portion rotatably coupled to the seat cushion.

A personal heating ventilation and air conditioning system (HVAC) for an aircraft seat includes at least one aircraft seat, a heating/cooling device disposed on the at least one aircraft seat and at least one branch configured to provide at least one flow path from the heating/cooling device. The system also includes at least one sub-branch provided within the at least one aircraft seat. The at least one sub-branch is configured to provide flow from the at least one branch through the at least one aircraft seat. The system also includes means for expelling air from the at least one sub-branch to an interior surface of the at least one aircraft seat.

A thermoelectric device is disclosed. The thermoelectric device comprises: a body part comprising a hollow in which a semiconductor device is disposed; a plurality of connecting parts protruding on the lateral sides of the body part and comprising connecting holes; and a plurality of electrode parts connected to the semiconductor device and extending to the connecting holes of the connecting parts.

A system having a controller includes one or more thermal generation element assemblies, or a plurality of air bladder assemblies, or a plurality of electromagnetic coil assemblies, or a combination thereof, that are in communication with the controller and are configured for activation by the controller. The one or more thermal generation element assemblies, or the plurality of air bladder assemblies, or the plurality of electromagnetic coil assemblies, or a combination thereof are configured to provide a holistic mitigating effect on a vehicle occupant confined within the interior space of a vehicle for long periods of time.

A seat assembly may include a seat including a seat base and a seat back, a sensor, a vent unit disposed at least partially within the seat back, and/or an electronic control unit (ECU) connected with the sensor and the vent unit. The ECU may be configured to determine, via the sensor, if a user of the seat exhibits symptoms of fatigue. The ECU may be configured to operate the vent unit in a first mode and a second mode. When the vent unit is in the first mode, the vent unit may provide cool air to said user of the seat. When the vent unit is in the second mode, the vent unit may provide warmer and/or less air to said user of the seat. The ECU may automatically switch the vent unit between first and second modes to reduce symptoms of fatigue.

A vehicle seat has at least one occupant comfort actuator suited for acting on a part of the body of an occupant of the seat. The actuator is driven based on at least one measurement of one sensor of sweat from the occupant of the seat.

A vehicle occupant air curtain system includes a seat that has a seat cushion and a seat back. The seat back has a region that is configured to be arranged above an occupant shoulder. An air vent is supported on the seat back and is arranged in the region. The air vent is configured to be directed adjacent to a seated occupant's head and neck.

An occupant support comprises a vehicle seat including a cushion and trim positioned around at least a portion of the cushion. The occupant support includes an occupant-comfort system having a heat transfer station positioned in the seat cushion in spaced-apart relation to the trim and configured to move selectively heat to an occupant in a heating mode and away from the occupant in a cooling mode.

A method of controlling a temperature altering element within a seating assembly of a vehicle comprising: presenting a vehicle including a seating assembly including a temperature altering element, a controller in communication with the temperature altering element, the controller including a Pre-established Predictive Activation Model setting forth rules governing the activation of the temperature altering element as a function of data relating to Certain Identifiable Conditions, and a user interface configured to allow the temperature altering element to be manually activated or deactivated; occupying the seating assembly with a first occupant; collecting data relating to the Certain Identifiable Conditions while the first occupant is occupying the seating assembly; determining, by comparing the collected data to the rules of the Pre-established Predictive Activation Model, whether the collected data satisfies the rules of the Pre-established Predictive Activation Model so as to activate the temperature altering element; and activating the temperature altering element.
