Abstract: A seat element having a cover and padding configured to serve as support for a user, and having a ventilation and thermal control system that includes a thermoelectric module, a blower, and a conduit delimiting a passage for air connecting the blower and the thermoelectric module. The ventilation and thermal control system is configured for passing a flow of air coming from the cover towards the blower, and the thermoelectric module is configured for cooling and/or heating the airflow.

Abstract: The present disclosure relates to a seat member comprising a first shell, a second shell fixed to the first shell, and a padding covering the second shell such that the second shell is sandwiched between the first shell and the padding, the padding being configured to support a user, and a ventilation system comprising a fan and a duct, the duct being defined by the first shell and the second shell and forming an air passage placing the fan and padding in communication via holes in the second shell. The duct comprises a housing able to receive the fan, and the first shell comprises a door through which the fan can be placed in the housing, the fan having a first orifice for the passage of air between the exterior and the fan, the door having a hole located facing the first orifice.

Abstract: A seat element includes a supporting structure, padding resting on the supporting structure and configured to serve as a support for a user, and a ventilation system having at least one fan and at least one duct placing the padding and the fan in communication. The duct is formed of a flexible material which preferably comprises a foam of polyolefin and/or ethylene-propylene-diene monomer (EPDM) and/or acrylonitrile butadiene (NBR).

Abstract: A seat element that includes a supporting structure, a padding configured to serve as a support for a user, and a ventilation system having at least one fan and a duct defining an air passageway placing the fan and the padding in communication. The duct has a first member and a second member fixed to one another, the first member being arranged between the supporting structure and the padding.

Abstract: A heating device for a motor vehicle seat includes a mat having first and second resistors which can be controlled independently of one another. The first and second resistors respectively form a loop between their two terminals, the two loops thus formed being wholly or partly inscribed one inside the other.

Abstract: A centrifugal pump is provided capable of pumping liquid volume flow rates of at least 20 m3/sec. The pump includes a centrifugal impeller rotatable about an axis and operable to direct a liquid towards a concrete volute arranged around the impeller. The pump further includes fixed fin-like elements arranged between the impeller and the volute. The elements form a discontinuous barrier around the impeller and are effective to reduce uneven radial thrusts exerted by the water on the centrifugal impeller, while limiting the water flow rate in a simple and economic manner.
