Description
---` 2~62320 The present invention relates to a steering wheel cover and more particularly to a cover adapted to heat the steering wheel of a vehicle.
The steering wheel of a vehicle such as an automobile or truck can, in a Northern climate during the winter months, become sufficiently cold so as to cause discomfort to the driver of the vehicle. Even after the vehicle itself has warmed up, the steering wheel usually remains cold to the touch necessitating the wearing of gloves by the driver.
It has been proposed previously in the art to provide means for heating the ~teering wheels of vehicles and a variety of different proposals ranging from the use of hot air, heated coolants and electric resistance heating have been advanced. Some of these proposals have included the provision of heating elements as an integral part of the steering wheel; however, automotive manufacturers have not incorporated this provision into their automobiles. While there have also been a number of proposals which can be used as a retrofit device, these have not gained any wide acceptance by the public.
It is an object of the present invention to provide a steering wheel cover assembly which incorporates heating means and which assembly can be adapted to many different types of vehicles and steering wheels.

It is an object of the present invention to provide a steering wheel cover assembly which incorporates heating means and which assembly can be adapted to many different types of vehicles and steering wheels.
Generally, according to one aspect of the present invention, there is provided a steering wheel cover assembly, the steering wheel cover assembly comprising a cover member,
- 2 -~23~
an electrical resistance heating means associated with the cover member, a first structural element securable to a rotatable portion of a steerinq wheel assembly, electrical contact means associated with the first structural element, a second structural element securable to a non-rotatable portion of the vehicle approximate the steering wheel, the second element also having electrical contact means associated therewith, both of the first and second structural elements being juxtaposed to each other such that the electrical contact means of the first element and the electrical contact means of the second element are in electrical communication when the first element rotates, electrical power supply means associated with the second structural element, thermostat means for sensing and controlling the temperature of the cover member, and switch means for turning electric power to the heating means on and off.
In greater detail, the assembly of the present invention includes a steering wheel cover member having an exterior surface which may be formed of many different suitable materials providing the desired feel and esthetic appeal. Many different natural and/or synthetic materials or combinations thereof which are known in the art have been employed with conventional wheel covers and can be used with the present invention. Desirably, the material is of a somewhat resilient nature and has a suitable feel.
The steering wheel cover is preferably of a multi-layer construction and as discussed hereinbelow, includes resistance type heating means. The combination of different 20~2320 la~rers of material having different properties such as both electrical and thermal insulating properties is well known in the art and many such structures may be utilized.
Associated with the cover material is an electrical heating means of the electrical resistance type. The means of incorporation of the heating means and the particular type used may be selected from those well known to those knowledgeable in the art. Many different types are commerciallly available. The cover member may be secured to the wheel by any suitable and conventional attachment means including draw strings, removable and/or permanent fasteners, etc.
The asqembly will include means for regulating the heat supplied to the cover member such that when a desired température is obtained, the unit will cease heating. There are many different types of thermostats which can be utilized; one of the easiest and most inexpensive would be the use of a bi-metal thermostat which is located on the steering wheel rim or close thereto in order to sense the temperature of the rim.
A switch device is also preferably included in the assembly and provides means for turning the assembly on and/or off as desired and/or required. In this respect, the circuitry is very basic and suitable power leads are supplied as will be discussed in greater detail with respect to the preferred embodiment of the invention.
~ he assembly includes first and second structural elements which permit a continuous supply of power to the heating means irrespective of the rotational movement of the 2~2320 steering wheel.
The first structural element is adapted to be secured to a rotatable portion of the steering wheel assembly such that it will rotate with the turning of the steering wheel. The point of attachment will depend upon the particular type of steering wheel involved; in a relatively straightforward arrangement, the first structural element may be secured to the hub of the steering wheel which is usually formed integrally with the rim and spoke portions. When this is not suitable, it may be attached to the steering wheel rim and spoke themselves. It will be understood that many suitable forms of attachment may be utilized; in the simplest form, the first structural element is formed in two parts (two halves) to provide for ready assembly of the same about the hub of the steering wheel assembly. Mechanical fastening means such as bolts or clips may be provided. Alternatively, straps or a more permanent securement by adhesive means or mechanical fasteners may be utilized.
The first structural element, being secured to the rotatable portion of the steering wheel assembly, will provide electrical communication to the electric heating means of the steering wheel cover. The first structural element will also provide electrical contact means for receiving power from the second structural element. In this respect a conventional 12 volt direct current heating which draws power from the vehicle's electric circuit may be employed.
The second structural element is designed to be juxtaposed to the first structural element and is adapted to ~, .
~ - 5 -, , 20~232~
be fixed to a non rotatable portion of either the steering wheel assembly or a surrounding portion of the vehicle. The second structural element is designed to provide electrical contact means which will remain in electrical communication with the electric contact means of the first structural element. The arrangement is such that rotatable movement of the steering wheel and first structural element will permit electrical contact between the two different electric contact means at all positions of the steering wheel. To maintain electrical contact, one of the contact means may be biased or other spring means may be used. In turn, the electrical contact means of the second structural element will receive DC power from a suitable source of the same - it may be directly wired to one of the vehicle circuits or alternatively, there may be provision for drawing power from an accessory outlet such as the cigarette lighter.
