Abstract
An electric heating blanket including a flexible sheet-like heating element and a shell. The shell covers the heating blanket and includes two sheets of flexible material welded together.
Claims40
An electric heating blanket, comprising:
- a flexible sheet-like heating element including an upper edge, a lower edge, and at least two side edges;
- a shell covering the heating element and comprising at least two sheets of flexible material;
- and
- a weld coupling the two sheets of flexible material together about the edges of the heating element, wherein the weld is one of a RF weld, ultrasonic weld, or a heat bond, wherein the two sheets comprise PVC.
