Heating cushion

Abstract

A heating cushion comprising an elastic main body having a cutting line provided thereon; a heating device, which consists essentially of an electrical heating cord that can be inserted in the body from the cutting line, a female connector joins with two ends of heating cord respectively, and a male connector pairs up with the female connector for supplying power to the heating cord; and an adhesive layer, made of a binding material, applied in an inner portion of the cutting line. The heating cord and said two electrical cords connecting to the heating cords can be coupled to the bottom of the cutting line by said adhesive layer. The heating cord within the cushion has even heat conductivity and flexibility, which won't be broken easily to avoid the occurrence of short circuit.

1 . A heating cushion comprising:
 a heating device, enclosed within a compartment made by two plastic casings, which sealed by high frequency wave; the heating device including a flexible electrical heating cord selected from carbon fiber, metallic fiber or graphite fiber;   a first connecting unit, having two electrical cords connecting both ends of the heating cord to form a electrical circuit;   a second connecting unit, engaged with the first connecting unit, and supplying power through a plug, an adapter and an electric cord;   an adhesive layer made of waterproof material for attaching said electrical cords of the first connecting unit and the heating cushion.   
     
     
         2 . The heating cushion of  claim 1 , wherein at least two openings are defined on each plastic casing. 
     
     
         3 . The heating cushion of  claim 1 , wherein said plastic casing is selected from a transparent or a non-transparent heat resisting plastic, silicone or rubber. 
     
     
         4 . The heating cushion of  claim 1 , wherein a temperature controlling device is provided between said second connecting unit and adapter. 
     
     
         5 . A heating cushion comprising:
 an elastic main body, having a cutting line set thereon;
 a heating device, including at least one heating cord provided in the cutting line, a female connector join with two ends of heating cord respectively, and a male connector pair up with the female connector for supplying power to the heating cord; and; 
 an adhesive layer, made of a binding material, is applied in an inner portion of the cutting line; the heating cord and said two electrical cords connecting the heating cords are coupled to a bottom of the cutting line by the adhesive layer. 
   
     
     
         6 . The heating cushion of  claim 5 , wherein the main body is selected from a back cushion, a chair cushion, a seat cushion, a sofa cushion, a sport cushion, a floor cushion or a mattress. 
     
     
         7 . The heating cushion of  claim 5 , wherein the heating cord is flexible and is selected from carbon fiber, metallic fiber or graphite fiber. 
     
     
         8 . The heating cushion of  claim 5 , wherein the female connector has two electrical cords for connecting with both ends of the heating cords. 
     
     
         9 . The heating cushion of  claim 5 , wherein the male connector including an electrical cord and an adapter and a plug connected electrically to the cord. 
     
     
         10 . The heating cushion of  claim 5 , wherein the male connector including an electrical cord and an adapter connected electrically to the cord; a temperature controlling device is further provided between said male connector and adapter. 
     
     
         11 . The heating cushion of  claim 5 , wherein both ends of said cutting line are provided on a side face of the main body and an opening is set on both ends thereof respectively. 
     
     
         12 . The heating cushion of  claim 5 , wherein said opening has a fixed member for securing the electrical cords attached to the heating cords.
