Abstract
Abstract A motor vehicle is provided with a body having a supporting structure of sheet metal and external lateral walls which below a substantially horizontal line extending above the vehicle wheels, comprises exclusively parts of plastics material. As compared with sheet metal parts, the plastics-material parts present a number of advantages including simpler assembly, better corrosion resistance and reduced susceptibility to damage in a minor collision.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
258 words
A motor vehicle having front and rear wheels and a body including side walls each having windows and at least one door, the lower edges of said windows defining a substantially horizontal belt line, each of said side walls below said belt line being comprised of an internal sheet metal wall and an external wall spaced from each other, said body having horizontal line defining means extending about said body on the external surface thereof immediately above said wheels and spaced below said belt line, the external wall of each side wall between said belt line and said line defining means being comprised of sheet metal and the external wall of each side wall below said line defining means being constructed solely from plastic material parts, wherein considered in a vertical plane containing the axes of the vehicle front wheels, each said first plastic material part has a cross-sectional profile which arches like a roof over the corresponding front wheel and comprises a horizontal central portion, a vertical flange extending upwards from said central portion and serving to facilitate the secural of said first plastic material part to said metal structure of said body, a downwardly-inclined, straight portion connected to the end of said central portion nearest the interior of said body, and a downwardly-inclined, curved portion connected to the end of said central portion nearest the exterior of said body, the concave face of said curved portion facing upwards and outwards and said curved portion constituting a part of the external lateral wall of the vehicle body.
Claim 2
Dependent Claim
258 words
A motor vehicle having front and rear wheels and a body including side walls each having windows and at least one door, the lower edges of said windows defining a substantially horizontal belt line, each of said side walls below said belt line being comprised of an internal sheet metal wall and an external wall spaced from each other, said body having horizontal line defining means extending about said body on the external surface thereof immediately above said wheels and spaced below said belt line, the external wall of each side wall between said belt line and said line defining means being comprised of sheet metal and the external wall of each side wall below said line defining means being constructed solely from plastic material parts, wherein considered in a vertical plane containing the axes of the vehicle front wheels, each said first plastic material part has a cross-sectional profile which arches like a roof over the corresponding front wheel and comprises a horizontal central portion, a vertical flange extending upwards from said central portion and serving to facilitate the secural of said first plastic material part to said metal structure of said body, a downwardly-inclined, straight portion connected to the end of said central portion nearest the interior of said body, and a downwardly-inclined, curved portion connected to the end of said central portion nearest the exterior of said body, the concave face of said curved portion facing upwards and outwards and said curved portion constituting a part of the external lateral wall of the vehicle body.
Claim 3
Dependent Claim
247 words
A motor vehicle having front and rear wheels and a body including side walls each having windows and at least one door, the lower edges of said windows defining a substantially horizontal belt line, each of said side walls below said belt line being comprised of an internal sheet metal wall and an external wall spaced from each other, said body having horizontal line defining means extending about said body on the external surface thereof immediately above said wheels and spaced below said belt line, the external wall of each side wall between said belt line and said line defining means being comprised of sheet metal and the external wall of each side wall below said line defining means being constructed solely from plastic material parts, wherein each lateral wall of said body includes a door and wherein the portion of said lateral wall comprised between the rear end of the vehicle and said door is defined, below the said horizontal line, by a said plastic material part which considered in a vertical plane containing the axes of the rear wheels of the vehicle, has a cross-sectional profile comprising a U-shaped portion serving for the secural of the said plastic material part to the said metal structure of the body, and a straight portion connected to the end of said U-shaped portion nearest the exterior of said body and inclined downwards therefrom, said straight portion constituting a part of the external lateral wall of the vehicle body.
Claim 4
Dependent Claim
247 words
A motor vehicle having front and rear wheels and a body including side walls each having windows and at least one door, the lower edges of said windows defining a substantially horizontal belt line, each of said side walls below said belt line being comprised of an internal sheet metal wall and an external wall spaced from each other, said body having horizontal line defining means extending about said body on the external surface thereof immediately above said wheels and spaced below said belt line, the external wall of each side wall between said belt line and said line defining means being comprised of sheet metal and the external wall of each side wall below said line defining means being constructed solely from plastic material parts, wherein each lateral wall of said body includes a door and wherein the portion of said lateral wall comprised between the rear end of the vehicle and said door is defined, below the said horizontal line, by a said plastic material part which considered in a vertical plane containing the axes of the rear wheels of the vehicle, has a cross-sectional profile comprising a U-shaped portion serving for the secural of the said plastic material part to the said metal structure of the body, and a straight portion connected to the end of said U-shaped portion nearest the exterior of said body and inclined downwards therefrom, said straight portion constituting a part of the external lateral wall of the vehicle body.
