Abstract
Abstract The bodywork is accomplished with longitudinal members of the passenger compartment, and with upper crosspieces of the doors, which can be adapted to different models of automobiles by means of the use of supplementary section bars. This is done according to whether the bodywork is accomplished with doors of traditional type, or with doors of the so-said "enveloping" type. To the longitudinal member or to the structure of the crosspiece of the door at least a supplementary section bar is fastened. In particular, it is welded and shaped as to at least partially seal the longitudinal chamber defined between the longitudinal member and the structure of the crosspiece.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
219 words
Bodywork for an automobile, the automobile having a plurality of doors, each door having a glass window panel, the bodywork comprising a longitudinal member, the longitudinal member having a plurality of steel plates which are welded together to form a box-type beam, one of said steel plates having a substantially horizontal upper flange extending towards the doors, each door having a rim, the rim of each door being sealable with the longitudinal member, the rim having a first crosspiece, the first crosspiece being a structure formed of at least one first section bar, the first section bar having a substantially "C"-shaped cross-section and extending downward to receive the glass window panel, a longitudinal chamber being positioned between the longitudinal member and the first crosspiece structure of each door, a supplemental section bar being positioned and shaped to partially seal the longitudinal chamber, a first sealing gasket for sealing the first crosspiece of each door with the longitudinal member, and a second sealing gasket for sealing the supplemental section bar with the longitudinal member, the supplemental section bar being secured to the longitudinal member, and the supplemental section bar having a wall with an arcuate cross-section and being curved to conform to outer outlines of the longitudinal member and the first crosspiece whereby aerodynamic resistance of the automobile is improved.
Claim 2
Dependent Claim
219 words
Bodywork for an automobile, the automobile having a plurality of doors, each door having a glass window panel, the bodywork comprising a longitudinal member, the longitudinal member having a plurality of steel plates which are welded together to form a box-type beam, one of said steel plates having a substantially horizontal upper flange extending towards the doors, each door having a rim, the rim of each door being sealable with the longitudinal member, the rim having a first crosspiece, the first crosspiece being a structure formed of at least one first section bar, the first section bar having a substantially "C"-shaped cross-section and extending downward to receive the glass window panel, a longitudinal chamber being positioned between the longitudinal member and the first crosspiece structure of each door, a supplemental section bar being positioned and shaped to partially seal the longitudinal chamber, a first sealing gasket for sealing the first crosspiece of each door with the longitudinal member, and a second sealing gasket for sealing the supplemental section bar with the longitudinal member, the supplemental section bar being secured to the longitudinal member, and the supplemental section bar having a wall with an arcuate cross-section and being curved to conform to outer outlines of the longitudinal member and the first crosspiece whereby aerodynamic resistance of the automobile is improved.
Claim 3
Dependent Claim
55 words
The bodywork according to claim 1, wherein the rim of each door has a second crosspiece, the second crosspiece being a structure formed of at least one second section bar, the second section bar having a substantially "U"-shaped cross section, and the first and second section bars of each door are integral with one another.
Claim 4
Dependent Claim
38 words

Claim 5
Dependent Claim
22 words
The bodywork according to claim 3, wherein the remaining wall of the three walls of the longitudinal member has a longitudinal bulge.
