2. Description of the Prior Art 
The use of interior heating system for an automobile is known in the prior 
art. More specifically, interior heating system for an automobile 
heretofore devised and utilized for the purpose of heating the interior of 
an automobile is known to consist basically of familiar, expected, and 
obvious structural configurations, notwithstanding the myriad of designs 
encompassed by the crowded prior art which has been developed for the 
fulfillment of countless objectives and requirements. 
By way of example, U.S. Pat. No. 4,713,522 to Kimura discloses an 
electrical heating appliance detachably mounted in a motor vehicle. U.S. 
Pat. No. 4,591,691 to Babali discloses an auxiliary electric heating 
system for internal combustion engine powered vehicles. U.S. Pat. No. 
4,520,258 to Trohmann discloses a system concomitantly controlling 
passenger compartment and electrical auxiliary heating in automatic 
vehicles. U.S. Pat. No. 4,293,759 to Higgins discloses an electric heating 
system for heating the interior of a motor vehicle prior to starting. U.S. 
Pat. No. 3,870,855 to Edlund and Wiksterom discloses an electric heating 
and battery charging system for motor vehicles. Lastly, U.S. Pat. No. 
3,469,072 to Carlson discloses an electric heating system for motor 
vehicles. 
While these devices fulfill their respective, particular objectives and 
requirements, the aforementioned patents do not describe electrical heater 
device for heating the interior of an automobile that allows heating of 
the interior portion of an automobile compartment while waiting for the 
main heating core assembly to provide the heat and structured to attach to 
the main heating core assembly of the automobile. 
In this respect, the electrical heater device for heating the interior of 
an automobile according to the present invention substantially departs 
from the conventional concepts and designs of the prior art, and in doing 
so provides an apparatus primarily developed for the purpose of heating 
the interior of an automobile prior to the main heating core assembly 
increasing the temperature of the interior of the automobile, and further 
providing a temperature sensor which allows the device to be turned off 
automatically. 
Therefore, it can be appreciated that there exists a continuing need for a 
new and improved electrical heater device for heating the interior of an 
automobile which can be used for heating the interior of an automobile 
prior to the main heating core assembly increasing the temperature of the 
interior of the automobile, and further providing a temperature sensor 
which allows the device to be turned off automatically. In this regard, 
the present invention substantially fulfills this need.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
With reference now to the drawings, and in particular to FIG. 1 thereof, 
the preferred embodiment of the new and improved electrical heater device 
for heating the interior of an automobile embodying the principles and 
concepts of the present invention and generally designated by the 
reference numeral 10 will be described. 
The present invention, the electrical heater device for heating the 
interior of an automobile 10 is comprised of a plurality of components. 
Such components in their broadest context include a housing, heating 
coils, a switch mechanism and a temperature sensor. Such components are 
individually configured and correlated with respect to each other so as to 
attain the desired objective. 
Specifically, the present invention includes a generally rectangular 
housing 12. The housing is formed of a metal alloy that has a good 
tolerance for high temperatures. The housing has a plate top 14, a bottom 
plate 16 and a pair of side plates 18 therebetween. The housing has a 
length of about eight inches, a height of about six inches and a width 
being about one-half inch. The housing is capable of being fixedly mounted 
to a heater core assembly 20 of an automobile 22. As shown in FIG. 2, the 
sides of the housing allows the housing to be mounted to the rear of the 
heater core assembly. The housing when attached to the heater core 
assembly of the automobile is spaced from the an engine 24 of the 
automobile, as illustrated in FIG. 1. 
The housing 12 has a first electrical wire 30 positioned on an interior 
surface 32 of the top plate 14. As shown in shown in FIG. 3, the first 
wire enters the housing through an exterior surface of the top plate. The 
first wire continues along the top plate and extends along an interior 
surface 34 of one of the side plates 18. The first wire has a housing wire 
end 38 spaced from an attaching position 40 of the bottom plate and one of 
the side plates 18. Additionally, the housing has a second electrical wire 
42 positionable therein. The second electrical wire is positioned in a 
continuous series within the housing. The second wire forms a plurality of 
linear portions 44 along a horizontal axis within the housing. The end of 
several of the linear portions have a loop 46 formed thereon before each 
linear portion continues within the housing along the parallel axis in a 
vertical plan. The second wire enters the housing through the exterior 
surface of the top plate adjacent the first wire 30. The second wire is 
capable of coupling with the first wire at the housing wire end. 
As best illustrated in FIG. 4, a plurality of heating coils 60 are 
provided. The plurality of heating coils are positioned along the second 
electrical wire when the second wire 42 is contained within the housing. 
The coils are randomly spaced along the second wire. Each coil is capable 
of emitting temperatures above seventy degrees celsius. The temperatures 
emitted from the coils are capable of heating the interior of the 
automobile. 
A switch mechanism 54, a shown in FIG. 1, is included. The switch mechanism 
has a knob 56 and a contact casing 58. The switch mechanism of FIG. 1, is 
positioned within the interior of the automobile, and within the reach of 
a driver. The contact casing and the knob of the switch mechanism are 
formed of a rigid plastic. The contact casing has a contact wire end 62 of 
the first wire 30 therein. The contact casing has a third electrical wire 
66 with a switching end 68 contained therein. The third electrical wire 
has a length for extending from the switch mechanism into as engine area 
of the automobile for coupling with a battery 72 of the automobile. 
The switch mechanism 54 is operated by pushing in the knob. When the switch 
is engaged, the switch allows an electrical bridge to form between the 
contact end 52 of the first wire 30 and the switching end 68 of the third 
wire 66. The electrical bridge transmits an electrical current through the 
third wire and into the first wire for charging of the plurality of 
heating coils 50 of the second wire within the housing. The heating coils, 
once charged convert the electrical current into heat. 
Lastly, a generally cylindrical temperature sensor 78 is provided. As shown 
in FIG. 1, the sensor is positionable around a fluid line 80 of the heater 
coil assembly 20 of the automobile 22. The temperature sensor has a sensor 
end 82 of the second wire 42 therein. The sensor is capable of receiving a 
fourth electrical wire 86 that extends from the sensor to the battery 72. 
The fourth electrical wire and the second wire form a contact relay 88 
within the temperature sensor, as shown in FIG. 6. The temperature sensor 
is any standard sensor that is used in automobiles. The contact relay is 
capable of being disrupted when the temperature sensor responds to the 
fluid line emitting a temperature of about seventy degrees celsius or 
above. Disruption of the contact relay will cause the heating coil to lose 
current which in turn will cause the switch mechanism to disengage or pop 
out. By having the sensor line the driver will not have to remember to 
turn off the electrical heater device once the main heating system has 
completely warmed up. 
The present invention is an electrical heater device for heating the 
interior of an automobile that may be attached to existing heater core 
assembly of the automobile. The device will assist in heating of the 
interior passenger compartment of the automobile while the driver is 
waiting for the heater core assembly to provide sufficient heat. The 
device is powered directly by the electrical supply (alternator/generator) 
of the automobile which allows it to come on readily when the button is 
pushed. The device is mounted to the heating core assembly with brackets 
so that its securely attached to the existing heating core assembly. The 
device has a temperature sensor which is wrapped around the fluid line of 
the heating core assembly. This temperature sensor is designed to react to 
an increase in temperature that is emitted from the fluid line. The 
increase in temperature will automatically cause the sensor to disrupt the 
current flow that is coming from the battery which in turn causes 
disruption of the current flow into the electrical heater device. 
Disruption of the current flow will cause the button to disengage which 
will turn the device off. The device allows the interior portion of the 
automobile to be heated at a faster rate while waiting for the fluid to 
flow through the engine and begin to heat the existing heating core 
assembly. 
As to the manner of usage and operation of the present invention, the same 
should be apparent from the above description. Accordingly, no further 
discussion relating to the manner of usage and operation will be provided. 
With respect to the above description then, it is to be realized that the 
optimum dimensional relationships for the parts of the invention, to 
include variations in size, materials, shape, form, function and manner of 
operation, assembly and use, are deemed readily apparent and obvious to 
one skilled in the art, and all equivalent relationships to those 
illustrated in the drawings and described in the specification are 
intended to be encompassed by the present invention. 
Therefore, the foregoing is considered as illustrative only of the 
principles of the invention. Further, since numerous modifications and 
changes will readily occur to those skilled in the art, it is not desired 
to limit the invention to the exact construction and operation shown and 
described, and accordingly, all suitable modifications and equivalents may 
be resorted to, falling within the scope of the invention.
