Abstract
Abstract The stabilizer according to the invention is made from a single pipe, and it comprises a torsion section coupled to a vehicle frame, curved sections integrally extending from the opposite ends of the torsion section and arm sections each integrally extending from each of the curved sections and coupled to a wheel suspension. Each of the curved sections has a flat section extending in the plane of action of the bending load applied to it.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
190 words
A hollow stabilizer for a vehicle made from a single hollow pipe, said single hollow pipe comprising: a hollow torsion section (1) coupled to the vehicle, said torsion section having a substantially circular cross-section; hollow curved sections (2) integrally extending from the opposite ends of said hollow torsion section (1); arm sections (3) integrally formed with, and extending from said curved sections (2) respectively, said arm sections (3) each having a cross-section substantially in the form of the letter I and which extends in a plane of action of the bending load applied to each said arm section; and coupling sections (4) integrally formed with, and extending from, said respective arm sections (3), said coupling sections each having a substantially circular cross sectional portion (4a) connected to the end of the respective arm section (3) and a substantially flat shaped portion (4b) extending from said substantially circular coupling section portion (4a) and adapted to be coupled to a wheel suspension, each substantially flat shaped portion (4b) of said coupling sections extending in a plane substantially perpendicular to the plane of said I-shaped cross sectional portion of said arm section (3).
Claim 2
Dependent Claim
