Abstract
Abstract This heating and ventilating system is adapted to deliver air in sheet form and comprises an upper hollow inlet beam associated with a helical fan and motor unit, an upper beam for de-misting and a lower beam for distributing air, which extend throughout the width of the vehicle, a casing comprising a pressurizing chamber, a heat exchanger, a mixing chamber equipped with shutters for controlling the ingress of reheated air, the opening of one of these last-named shutters being operatively connected to the inlet means for warm water from said exchanger and, in conjunction with the opening of the other shutter, a rheostat for starting said fan and motor unit.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
220 words
A heating and ventilating system for providing an air circulation in vehicles in the form of sheets spread throughout the width of the vehicle by using an assembly of hollow framestructure beams associated with a compact air-mixing apparatus, comprising: a first air inlet hollow beam closed by a bonnet formed with air inlet holes disposed at the base of the windscreen in a zone of pressurized air due to the relative wind; a helical-type motor and fan unit disposed in the lower portion of the air inlet beam and easily accessible by simply opening said bonnet and cooperating with a rheostat controlling the start and speed of the motor; an inner casing comprising a pressurizing chamber; a heat-exchanger of the warm water inlet type connected to the engine cooling system; a mixing chamber supplied through inlet shutters on the one side with air reheated through the heat exchanger and on the opposite side with external air at the atmospheric temperature, taken directly from said pressurizing chamber, the opening of the reheated air delivery shutter being operatively connected to the means supplying warm water to said heat exchanger, and the opening of the atmospheric air inlet shutter being jointly with said reheated air shutter operatively connected to said motor start rheostat, thus ensuring the desired air mixing in said mixing chamber.

Claim 3
Dependent Claim
167 words
A heating and ventilating system according to claim 1, wherein said mixing chamber is connected at one hand via a central duct adapted to be closed by a shutter to another beam extending throughout the width of the vehicle and formed in its upper portion with orifices adapted to direct air towards the lower portion of the windscreen for de-misting, de-icing and sheet ventilating same, and comprising on its rear face outlets connnected to air outlets directed towards the passengers of the vehicle and adjustable from the dual point of output and direction, and on the other hand by ducts adapted to be closed by shutters, to a second beam also extending throughout the width of the vehicle and underlying said first beam for de-misting and aerating the upper portion of the passengers'' compartment, said second beam being formed at its lower portion with orifices for distributing air to ducts means directed towards the floor of the vehicle for heating and ventilating the legs of the passengers.
Claim 4
Dependent Claim
59 words
Heating and ventilating system according to claim 2, wherein the inlet end of said duct supplying air to said first or upper beam is located in the vicinity of the inlet receiving the surrounding air, and that the inlets of said lateral ducts supplying air to said lower beam are located in the vicinity of the reheated air inlet.
Claim 5
Dependent Claim
20 words
Heating and ventilating system according to claim 3, wherein said shutters of the upper and lower beams are operatively interconnected.
Claim 6
Dependent Claim
24 words
Heating and ventilating systEm according to claim 4, wherein an air-conditioning apparatus is connected to said mixing chamber and utilizes the same distributing circuit.
Claim 7
Dependent Claim
180 words
A heating and ventilating system for vehicles comprising: an exterior air inlet comprising a hollow beam closed by a bonnet on the exterior of the vehicle, said bonnet having inlet apertures therein; an inner casing enclosing a pressurizing chamber; a motor driven helical fan in the lower portion of the inlet beam, said fan for moving air into said pressurizing chamber; a liquid-gas heat exchanger in the pressurizing chamber; a mixing chamber downstream of the pressurizing chamber, and one inlet shutter from the pressurizing chamber to the mixing chamber located downstream of the heat exchanger, and another inlet shutter from the pressurizing chamber to the mixing chamber located upstream of the heat exchanger; means for supplying warm fluid to the heat exchanger, including an inlet valve; a rheostat control means for coordinating said inlet valve, the upstream and downstream inlet shutters, and the fan motor; and a central duct connecting said mixing chamber and a hollow beam extending across the interior of the vehicle, having exit apertures for distributing a thin stream of air throughout the width of the vehicle.
Claim 8
Dependent Claim
180 words
