Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
95 words
In a motor vehicle having an internal combustion engine at the front and a rear axle structure adjacent the rear and an exhaust gas system for conducting exhaust gases from the engine to the rear of the vehicle on the remote side of the rear axle structure from the engine, said exhaust system including an arch shaped conduit assembly extending vertically up and over the rear axle structure, said assembly comprising two arch members coupled together in a gastight joint located substantially at the top of the arch shape and above the rear axle structure.
Claim 2
Dependent Claim
95 words
