Conditioned seat
First Claim
1. A conditioned seat, comprising:
- at least one seat contact surface, an outer side of which faces towards part of a passenger in said seat,an air-conditioning device which supplies air to a region of an inner side of said seat contact surface), said air having a water vapour partial pressure less than in a microclimate between said seat contact surface and a passenger in said conditioned seat,an electrical heating element arranged in said region of said inner side of said seat contact surface for warming said seat contact surface,a temperature sensor for detecting a temperature in said region of said inner side of said seat contact surface, anda controlling system which is in connection both with said air-conditioning device and with said electrical heating element and controls said air-conditioning device and said electrical heating element corresponding to a predetermined desired temperature value in dependence on said temperature measured by said temperature sensor,wherein said air-conditioning device comprises an air duct through which air is blown and a Peltier element having a first heat exchanger on a cooling side and a second heat exchanger on a heating side, said first heat exchanger extending into said air duct and said second heat exchanger extending into said air duct downstream of said first heat exchanger, a portion of said air duct downstream of said second heat exchanger being connected with an air supply system which supplies said air flowing through said air duct to said region of said inner side of said seat contact surface, with a drying means for drawing off water being arranged in said air duct between said first heat exchanger and said second heat exchanger.

Abstract
The conditioned seat, has at least one seat contact surface (31), the outer side of which faces towards part of a passenger in the seat. An air-conditioning device (18) supplies conditioned air to the region of the inner side of the seat contact surface (31). An electrical heating element (24) is arranged in the region of the inner side of the seat contact surface (31) for warming the seat contact surface (31). A temperature sensor (28) detects the temperature in the region of the seat contact surface (31). For achieving a fast adjustment of the seat temperature to a preset desired temperature independent from the ambient temperature a controlling system (20) is provide which is in connection both with the air-conditioning device (18) and with the electrical heating element (24) and controls these corresponding to a pre-set desired temperature value in dependence on the temperature measured by the temperature sensor (28).

11. A method for temperature and moisture conditioning a seat, comprising the steps of:
-
cooling ambient air to create cool air; removing water moisture that is condensed out of said cool air to create cool dry air; heating said cool dry air to create heated dry air having an increased ability to hold moisture by having a lowered water vapour partial pressure; directing said heated dry air having a lowered water vapour partial pressure against an inner surface of a seat surface, wherein a temperature of said seat surface is lowered and moisture in a microclimate between said seat surface and a seat occupant is drawn through said seat surface and absorbed by said heated dry air due to a moisture-absorbing capacity of said heated dry air. - View Dependent Claims (12, 13, 14, 15, 16, 17)
