Abstract
Abstract A motor car dashboard, which is compact and has a self contained design and is functionally improved in that the scales of measure of certain magnitudes (e.g. Speed) are divided into staggered sectors corresponding to the most common fields of use, and in that it is possible to take immediate digital readouts of the most important physical magnitudes of interest for a motorist on a display screen, it being sufficient to depress a pushbutton which energizes an electronic readout apparatus for each magnitude of interest and causes the display to be shown on said screen.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
115 words
A dashboard for a motor vehicles, said dashboard comprising a single panelboard including at least one speedometer scale with a pointer for indicating the speed of the vehicle and at least one engine RPM meter scale with a pointer for indicating the RPM of the vehicle engine, wherein said single panelboard further includes a number of control members and a first display controlled by said control members for selective indication of a corresponding number of measured physical magnitudes said speedometer having a bar-type scale partitioned into sectors, each sector comprising graduations of preselected values of the speed of the vehicle, the graduations of each sector being arranged staggered relative to those of the preceding sector.
Claim 2
Dependent Claim
115 words
A dashboard for a motor vehicles, said dashboard comprising a single panelboard including at least one speedometer scale with a pointer for indicating the speed of the vehicle and at least one engine RPM meter scale with a pointer for indicating the RPM of the vehicle engine, wherein said single panelboard further includes a number of control members and a first display controlled by said control members for selective indication of a corresponding number of measured physical magnitudes said speedometer having a bar-type scale partitioned into sectors, each sector comprising graduations of preselected values of the speed of the vehicle, the graduations of each sector being arranged staggered relative to those of the preceding sector.
Claim 3
Dependent Claim
48 words
A dashboard according to claim 1, wherein said RPM meter has a bar-type scale which is partitioned into sectors, each sector comprising graduations of preselected values of the rotational speed of the engine, the graduations of each sector being arranged staggered relative to those of the preceding sector.
Claim 4
Dependent Claim
33 words
A dashboard according to claim 2, wherein said single panelboard further includes a second display operatively connected to said speedometer and adapted to display a digital indication of the speed of the vehicle.
Claim 5
Dependent Claim
61 words
A dashboard according to claim 3, wherein said single panelboard further includes a scale of a pressure gauge with a pointer for indicating the engine oil pressure, a scale of a thermometer with a pointer for indicating the engine coolant temperature and a scale of a fuel level gauge with a pointer for indicating the fuel level in a fuel tank.
Claim 6
Dependent Claim
32 words
A dashboard according to claim 4, wherein said single panelboard further includes a number of pilot symbols combined with respective pilot indicators for preselected functions of the vehicle and the vehicle engine.
Claim 7
Dependent Claim
20 words
A dashboard according to claim 4, wherein said pressure gauge, said thermometer and said fuel level gauge have bar-type scales.
Claim 8
Dependent Claim
30 words
A dashboard according to claim 6, wherein said scales of the speedometer, the RPM meter, the pressure gauge, the thermometer and the fuel level gauge are superimposed to each other.
Claim 9
Dependent Claim
24 words
A dashboard according to claim 7, wherein said scales and said displays are framed by fixed ribs projecting substantially perpendicularly to the panelboard plane.
Claim 10
Dependent Claim
76 words
A dashboard according to claim 6, wherein each of said scales has a pointer formed by a set of optical electronic elements which are lit up in succession in variable number to indicate the instantaneous value of the corresponding physical magnitude, said optical electronic elements being actuated by control circuits operatively connected to measuring instruments, said optical electronic elements and said control circuits being supported by a first plate placed behind said panelboard and assembled therewith.
Claim 11
Dependent Claim
26 words
A dashboard according to claim 9, wherein said control circuits are arranged to emit trains of current pulses having rectangular waves of appropriate frequency and intensity.
Claim 12
Dependent Claim
75 words
A dashboard according to claim 9, wherein a second plate is placed adjacent said first plate, said second plate supporting logical circuits of apparatus for the adjustment of the fuel injection and of the ignition of the engine, a third plate supporting power stages of said logical circuits being located adjacent said second plate, said second and third plates being assembled with said first plate and said panelboard so as to make an entity therewith.
Claim 13
Dependent Claim
66 words
A dashboard according to claim 9, wherein said panelboard includes a light-sensitive probe for detecting the intensity of the light impinging on said panelboard from the interior of the vehicle, said probe being operatively connected to current feed means for said optical electronic elements so as to regulate the intensity of illumination of said elements consistently with the light conditions in the interior of the vehicle.
