Abstract
A temperature regulating foam padding including a plurality of zones, at least one passive cooling device, disposed in at least a first zone of the plurality of zones, at least one heating device, disposed in at least the first zone, at least one temperature sensor and/or heart rate sensor, disposed in the first zone, and a controller, connected to the heating device and the sensor(s) for controlling the heating device. The passive cooling device is adapted to lower the temperature of the first zone to a first temperature (T1) below a desired temperature (T) and the heating device is adapted to increase the temperature of the first zone from the first temperature (T1) to the desired temperature (T).
Claims16
A temperature regulating foam padding comprising:
- a plurality of zones;
- at least one passive cooling device, disposed in at least a first zone of the plurality of zones;
- at least one heating device, disposed in at least one of the plurality of zones;
- at least one sensor, disposed in the first zone;
- and
- a controller, connected to the heating device and the at least one sensor for controlling the heating device;
- wherein the passive cooling device is adapted to lower the temperature of the first zone to a first temperature (T1) below a desired temperature (T);
- and
- the heating device is adapted to increase the temperature of the first zone from the first temperature (T1) to the desired temperature (T),
- wherein the passive cooling device is not adjustable and cannot be actively controlled;
- and
- wherein the heating device is controlled by the controller to compensate for a decrease of the temperature in the first zone below the desired temperature (T) caused by the passive cooling device.
A method for regulating the temperature of a foam padding, the foam padding comprising a plurality of zones, at least one heating device disposed in at least one of the plurality of zones, at least one sensor, disposed in at least the first zone, a controller, connected to the heating device and the at least one sensor, and at least one non-adjustable passive cooling device for lowering the temperature of the first zone to a first temperature (T1) below a desired temperature (T), the method comprising the steps of:
- measuring parameters in the first zone using the at least one sensor;
- allowing the at least one non-adjustable passive cooling device to lower the temperature of the first zone to a first temperature below the desired temperature (T);
- and
- controlling the heating device to compensate for the decrease of the temperature in the first zone below the desired temperature (T) caused by the passive cooling device and to increase and hold the temperature in the first zone at the desired temperature (T), using the controller.
