Abstract
A heating device for a vehicle seat having at least: one first heating element, which is arranged on or close to a first user-facing surface region of the vehicle seat, the structure and operating principle of which is designed for a conductive transfer of heat to a passenger, and a further heating element the operating temperature of which in at least one operating state is greater than the operating temperature of the first heating element and the surface temperature of which generated at a further surface region of the vehicle seat is alternatively or additionally greater than that of the first heating element within the first surface region.
Claims18
A heating device for a seat comprising:
- a first heating element which is arranged on or close to a first user-facing surface region of the seat, and configured for a conductive transfer of heat, and
- a further heating element configured to have:
- an operating temperature in at least one operating state that is greater than an operating temperature of the first heating element, and
- a surface temperature generated at a further surface region of the seat that is alternatively or additionally greater than the first heating element within the first user-facing surface region,
- wherein the further heating element is controlled such that the surface temperature at the further surface region of the seat and/or the further heating element is a predetermined temperature if the further surface region of the seat is not touched by a user, and the further heating element is controlled to reduce the surface temperature at the further surface region of the seat if the further surface region of the seat is touched by the user, wherein the predetermined temperature is or exceeds 50° C.
A heating device for a seat having at least:
- a first heating element that is configured to be arranged on or close to a first user-facing surface region of the seat for conductive heat transfer, and
- a second heating element that is configured to be arranged on or close to a second user-facing surface region of the seat;
- wherein the first heating element and the second heating element are controlled so that the second heating element operates at a higher temperature than the first heating element, and
- wherein when the second user-facing surface region of the seat is touched by a user, a temperature of the second heating element is reduced below a set temperature, and when the second user-facing surface region of the seat is no longer touched by the user, then the temperature of the second heating element is increased to or above the set temperature when the set temperature is or exceeds 50° C.
