Abstract

A combination heater and sensor comprising: (a) a heating layer, a sensing layer, or both; (b) one or more power application portions, one or more sensing application portions, or both; wherein the heating layer and the sensing layer are located within the same plane; and wherein the heating layer is a nonwoven layer that is comprised of a plurality of metallized fibers that are randomly oriented forming the heating layer so that upon application of power the heating layer provides heat.

Description

technical field [0001] The present teachings generally relate to devices that include both heating and sensing capabilities such that all or a portion of an occupant is sensed and heated. Background technique [0002] The present teaching is based on providing an improved heater, more preferably an improved heater for use in a vehicle. Generally, a heater includes a wire formed in a pattern. When power is applied to the wire, the wire generates heat. The wire may also be disposed in a carbonaceous material such that as the wire heats up, heat diffuses into the carbonaceous material to heat a larger area. However, uniform heating cannot always be achieved in these devices and hot spots can occur around the heating wires. Also, if the heater wire breaks, the heater may stop heating. The heater may also include electrodes connected with a positive temperature coefficient material such that electricity is conducted from one electrode to the other via the positive temperature...
