Abstract
A conditioning system for a vehicle passenger seat and a vehicle passenger seat assembly, the system including at least one conditioning unit including a Venturi device configured to generate air flow relative to a seat element and a temperature element configured to heat or cool the Venturi device or the air flow, a temperature sensor configured to sense a temperature in relation to the at least one conditioning unit, and a controller communicatively coupled to the temperature sensor and operably coupled to the at least one conditioning unit. The controller is configured to operate in a first operating condition in which the Venturi device is activated and the temperature element is inactive to ventilate the seat, and a second operating condition in which both the Venturi device and the temperature element are activated to heat or cool the seat.
