FIG. 7  is a use state view of a heating blanket for a motorized wheelchair according to the present invention. 
     As shown in  FIGS. 1 to 6 , according to a heating blanket for a motorized wheelchair  100  comprises a windproof and waterproof fabric  10  which covers a thermal lining having Velcro fasteners  34  attached to at least one position thereof, has windproof and waterproof functions, and has a zipper  62   a  and  72   a  and a zipped entrance/exit  62  and  72  formed on the front and back sides thereof; at least one heating plate  110  which is inserted into a back side (polarpolis fabric) windproof and waterproof fabric  10  via the zipper  72   a  and is detachably mounted on the thermal lining  30 , wherein the heating plate is woven with carbon yarns so that the heating plate generates heat when electricity is applied; an electric wire  122 , a connection part  124 , an adjustment part  132 , and a connection jack  146  for supplying electricity to the heat plate, wherein the heating blanket is characterized in that the connection jack  146  is connected to the outside to allow the heating plate to be heated by receiving power of 24V from a power supply unit of the motorized wheelchair, wherein the front side of the windproof and waterproof fabric is provided with an upper pocket part  20  which covers the zipped entrance/exit  62  and of which both the upper side and the lower side, except for a hand entrance/exit slot  24  and  25 , are sewn. 
     A luminous band  32  is added to the front side of the windproof and waterproof fabric  10 . 
     Male and Female Velcro fasteners  11   a  and  11   b  are mounted to the front side of the windproof and waterproof fabric  10  and then after wearing it, both sides thereof are mutually fixed with each other. 
     The connection jack  146  is connected with a power supply unit mounted to the motorized wheelchair W and so the heating plate  110  is heated by receiving the power. 
     At the lower back end side  12  of the windproof and waterproof fabric  10  is provided with at least one or more pocket parts  153  and  163  for covering feet. 
     One or more upper pocket parts  20  can be mounted to proper positions. 
     In  FIG. 1 , the size and position of the zipper  72   a  and the zipper entrance/exit  72  can be changed more bigger and so can be modified according to the size of the heating plate  110 . 
     As shown in  FIG. 5 , the heating plate  110  is combined with a Velcro fastener  34  located at a constant position of the thermal lining  30  through a Velcro fastener  112 . The thermal lining  30  can be formed by a fabric with a Velcro material. The thermal lining  30  is sewn by forming a sewing part  111  at the circumferential part within the windproof and waterproof fabric  10 . 
     According to the present invention as described above, when using a heating blanket for a motorized wheelchair  100 , a user opens a zipper  72   a  of a back side  12  of the heating blanket  100 , inserts the heating plate  110  through a zipper entrance/exit  72  and then attaches it to a desired position (for example, desired positions such as knee, calf, ankle and so on) of a thermal lining.

Also, the user can take out the connection jack  146  (it can connect with a power supply part of a motorized wheelchair) to connect it to the power supply part (which refers to  FIG. 7 .) 
     On the other hand, as shown in  FIG. 6 , a user can use a heating blanket for a motorized wheelchair of a windproof and waterproof fabric to cover his desired position at the state that he or she sits on the motorized wheelchair. A user can cover his feet by folding a foot portion in the heating blanket and using Velcro fasteners  11   a  and  11   b . Also, a user inserts his feet into pocket parts  153  and  163  positioned at the lower portions of the heating blanket  100  and so can obtain the thermal effect. Although two pocket parts are formed, a pocket part can be formed at the middle position of the heating blanket. 
     As described above, according to a heating blanket for a motorized wheelchair according to the present invention, a heating plate is detachably mounted to the inside of a blanket, a battery is installed at the motorized wheelchair, and a controller is installed at the front pocket of the blanket to connect the battery with the heating plate, thereby supplying power to the heating plate. In a state that a user sits on the motorized wheelchair or a motorized scooter, he or she can easily control the operation of the heating plate installed at a desired position. 
     Also, in the heating blanket for a motorized wheelchair according to the present invention, a space for receiving the feet of a user is equipped with a lower backside of the blanket and so after seating a user on the motorized wheelchair, the user&#39;s feet are easily covered on the move, the thermal effect of the feet is provided, the feeling of fatigue is reduced, and blood-flow disorders can be prevented. 
     The present invention can be applied identically to a motorized wheelchair and a motorized scooter. 
     In a windproof and waterproof fabric of the present invention, a front side thereof is a waterproof fabric and the back side thereof is a polarpolis fabric. 
     When making the inside of the windproof and waterproof fabric, that is, a portion at which a heating plate is installed, a material (Nyrex (trademark) fabric, or male Velcro fastener is spread thinly) that a Velcro fastener is unnecessary can be used and formed. In this case, a Velcro fastener (fixing member) installed at the heating plate is unnecessary, a user can attach the heating plate to the inside of the windproof an waterproof fabric.
