Abstract
Abstract A body of automotive vehicle, and more particularly of massproduced passenger vehicle, characterized in that its general configuration comprises two opposed irregular frustums of pyramid with non-parallel bases, assembled at their major bases, one frustum having an elongated shape converging to the front to constitute the passenger compartment and the front portion of the vehicle, its minor base constituting the front face and its major base corresponding to the greater cross-section of the vehicle body, which is located substantially at the rear of said passenger compartment, the other frustum being shorter and converging sharply to the rear, with the minor base constituting the rear end face of the vehicle and major base coplanar with that of the first or front frustum of pyramid, the perimeter of this major base following a contour slightly parallel to that the major base of said one frustum but being slightly recessed in relation thereto in order to provide a continuous, sharp-edged shoulder along the perimeter of said major base, on the faces corresponding to the roof and to the upper portion of the side panels of the body.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
192 words
A body of an automotive vehicle having a general configuration comprising two opposed irregular frustums of pyramids each having non-parallel bases, joined at their major bases, a first one of said frustums having an elongated shape converging toward the front of the vehicle to comprise a passenger compartment and the front portion of the vehicle, its minor base comprising the front face and its major base corresponding to the greater cross-section of the vehicle body which is located substantially at the rear of said passenger compartment, the second frustum being shorter than the first and converging sharply toward the rear of the vehicle, having a minor base which comprises the rear face of the vehicle and major base coplanar with the major base of the first frustum, the perimeter of this major base following a contour substantially parallel to that of the major base of said first frustum and being slightly smaller than and recessed in relation thereto in order to provide a continuous, sharp-edged shoulder along the perimeter of said major base on the faces corresponding to the roof and to the upper portion of the side panels of the body.
Claim 2
Dependent Claim
192 words
A body of an automotive vehicle having a general configuration comprising two opposed irregular frustums of pyramids each having non-parallel bases, joined at their major bases, a first one of said frustums having an elongated shape converging toward the front of the vehicle to comprise a passenger compartment and the front portion of the vehicle, its minor base comprising the front face and its major base corresponding to the greater cross-section of the vehicle body which is located substantially at the rear of said passenger compartment, the second frustum being shorter than the first and converging sharply toward the rear of the vehicle, having a minor base which comprises the rear face of the vehicle and major base coplanar with the major base of the first frustum, the perimeter of this major base following a contour substantially parallel to that of the major base of said first frustum and being slightly smaller than and recessed in relation thereto in order to provide a continuous, sharp-edged shoulder along the perimeter of said major base on the faces corresponding to the roof and to the upper portion of the side panels of the body.
Claim 3
Dependent Claim
78 words
Vehicle body according to claim 1, wherein the body also comprises a third irregular frustum of a pyramid having non-parallel bases and a flattened configuration, with the minor base comprising the roof of the passenger compartment and the major base comprising the contour of the maximum surface area of the vehicle as seen in floor projection from above, said major base lying in a substantially horizontal plane close to the base or lower edge of the car body.
Claim 4
Dependent Claim
48 words
Vehicle body according to claim 1, wherein the surfaces comprising the top of the front portion, the windscreen, the roof of the passenger compartment, the upper portions of the side panels of the passenger compartment and of the front portion are inclined and converge in the forward direction.
Claim 5
Dependent Claim
24 words
Vehicle body according to claim 1, wherein aeroflow vents communicating with the passenger compartment are disposed in the recessed zone behind the sharp-edged shoulder.
Claim 6
Dependent Claim
