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.
Claims13
A seat element comprising a cover and padding configured to serve as support for a user and a ventilation and thermal control system, the cover representing a surface of the seat element which is in contact with the user, where the ventilation and thermal control system comprises at least one thermoelectric module, a blower, and a conduit delimiting a passage for air connecting the blower and the thermoelectric module,
- wherein the ventilation and thermal control system is configured for passing a flow of air coming from the cover towards the blower, the air passing the blower being directed towards a side of the seat element opposite the cover, and where the thermoelectric module is configured for cooling and/or heating the airflow,
- wherein the seat element comprises at least one heat exchanger able to improve heat exchange between the thermoelectric module and the airflow,
- wherein an upper surface of the thermoelectric module is in contact with the padding, and a lower surface of the thermoelectric module is in contact with the heat exchanger, and
- wherein the air drawn from the cover is used to cool the heat exchanger and thereby cool the lower surface of the thermoelectric module.
