BACKGROUND OF THE INVENTION This invention relates generally to heated clothing, and more particularly concerns a heated suit system which is modular and which enables selective wearing of certain sections of the suit without impairment of the heating function.

There is a nee'd'for heated'garments inmany sports and other activities, such as for example, motorcycling, snowmobile operation and the operation of construction equipment out of doors in cold climates. On the other hand, a complete heated suit may become locally uncomfortable to the wearer, to the extent that he requires heating of only a selected portion of a complete suit. To my knowledge, no prior heated clothing system embodies the unusual advantages in structure, function and result such as one found in the present system, and which overcome the above as well as other problems associated with prior equipment.

SUMMARY OF THE INVENTION It is a major object of the invention to provide a heated suit system overcoming the above problems and incorporating numerous unusual advantages as will appear. Basically, the clothing comprises multiple sections each adapted to cover a different portion of the human body; electrical wires carried by the sections and including interconnected bus and heater wires; separable electrical connections between the bus wires of adjacent clothing sections; and, input electrical connections to the bus wires of at least one of the clothing sections. As will appear that one section may cover the wearers waist andmay be associated with a jacket and- /or trouser section; electrical input leads may be connected with the input electrical connections which are releasable, and a current control may be connected with at least one of the input leads for suit temperature control, considering that greater current or power will be required the more suit sections are employed; the suit sections are typically separately fastened together, as will be seen, and they may include glove, hood, face mask and slipper sections as well as jacket and trouser sections.

These and otherobjects and advantages of the invention as well as the details of an illustrative embodiment will be more fully understood from the following description and drawings, in which:

DRAWING DESCRIPTION FIG. 1 is a side elevation showing a motorcyclist whose suit embodies the invention;

FIG. 2 is a showing. of the FIG. 1 suit, with same wiring details illustrated;

FIG. 3 is an enlarged section on line 33 of FIG. 2;

FIG. 4 is an enlarged fragmentary section, partly broken away, on line 4 -4 of FIG. 2;

FIG. 5 is an enlarged cross-section on line 5-5 of FIG. 4; and

FIG. 6 is a wiring diagram.

DETAILED DESCRIPTION In the drawings, the suit 10 comprises multiple clothing sections each adapted to'cover a different portion of the human body. For example, the suit 10 includes a jacket 11 to the arms 11a of which gloves 12 are attached as by snap fasteners 13, and to the neck 11b of which a hood 14 is attached as by snap fasteners 15. 5 Also, a face mask 16 is attached to the hood as by snap fasteners 17. The suit also includes trousers 18 having snap fastener attachment to the jacket at 19; and slippers 20 having snap fastener attachment to the trouser legs 180 at 21. The latter are shown in detail in FIG. 3, although other forms of fasteners may be employed.

Electrical wires are carried by each clothing section, and include bus wires and heater wires connected therewith (as for example between the bus wires). This is tabulated as follows, with added reference to FIG. 6:

In addition, separable electrical connections are established between the bus wires of adjacent clothing sections, as tabulated as follows:

30 Adjacent bus wires Separablc connectors 22 & 24 39 21 & 40 2| & 27 41 22 & 28 42 5 27 8t 43 3 2s & 3] 44 33 & 36 45 34 & 37 46 Further, input electrical connections are established to the bus wires of at least one of the clothing sections, and in the drawings such input connections are estab lished at 47 and 48 between input leads 49 and 50 and

jacket buses

21 and 22, respectively; and in addition are also established at 51 and 52 between input leads 49 and 50 and

trouser buses

33 and 34, respectively. All of the connectors are of the releasable plug-in type, as indicated in the drawings, so that, for example, if connections 51 and 52 are released, the trousers and slippers will not be heated; and if

connections

47 and 48 are released, the jacket and the gloves, face mask and hood will not be heated. It is also seen that various of the

connections

39 and 40, 41 and 42, 43 and 44, and and 46 may be unplugged to prevent heating of the associated clothing elements.

A current control is provided as at 60 in series with input leads 49 and to control the power or current supplied to the suit so as to vary the heating as required by the number of clothing sections remaining electrically connected with the input leads, as described. An AC or DC power source is indicated at 61, and may for example comprise a battery on the motorcycle. Merely as illustrative, a fully operating suit will draw between I to 1.5 amperes at about 12 volts.

The wires (bus and heater or resistance) may be embedded between clothing layers, as indicated in FIGS. 4 and 5 where bus wire 33 extends between

trouser leg layers

18a and 18a". Note that insulation 64 may surround the bus wire, and this construction may also be employed throughout. The clothing may comprise a liner for outer clothing, or it may comprise the main garment, with an insulative outer layer as at 65 in FIG.

5 The plug-in type connectors may include plugs and receptacles, with snap or screw-in retention. One commercial type connector is a product of BF. Johnson Company, and bears jack and plug numbers 108-0902-001, 108-0903-001, lO8-O302-00l, and 10 From the above, it is clear that the invention provides very simple and advantageous selectively wearable clothing sections which are selectively heated in response to electrical interconnection of the clothing sections.
