Abstract
Abstract The hollow stabilizer is made from a single pipe and has a torsion section coupled to a vehicle, curved sections each integrally extending from each end of the torsion section, and arm sections each integrally extending from each of the curved sections. All these sections have the same outer diameter, and the curved sections have an increased thickness compared to the rest of the stabilizer.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
112 words
A hollow stabilizer for a vehicle made from a single hollow pipe comprising: a torsion section adapted to be coupled to a vehicle frame; curved sections integrally extending from each end of said torsion section; and arm sections each integrally extending from each of said curved sections and having coupling means adapted to be coupled to a wheel suspension of the vehicle; said torsion section, said curved sections and said arm sections all having the same outer diameter; said curved sections having a smaller inner diameter than said torsion section and said arm section, and said curved sections thus having a greater wall thickness than said torsion section and said arm sections.
Claim 2
Dependent Claim
112 words
A hollow stabilizer for a vehicle made from a single hollow pipe comprising: a torsion section adapted to be coupled to a vehicle frame; curved sections integrally extending from each end of said torsion section; and arm sections each integrally extending from each of said curved sections and having coupling means adapted to be coupled to a wheel suspension of the vehicle; said torsion section, said curved sections and said arm sections all having the same outer diameter; said curved sections having a smaller inner diameter than said torsion section and said arm section, and said curved sections thus having a greater wall thickness than said torsion section and said arm sections.
Claim 3
Dependent Claim
20 words
A hollow stabilizer according to claim 1, wherein said torsion section and said arm sections have the same wall thickness.
