Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
95 words
A stabilizer for a vehicle, the stabilizer being a single, one piece, unitary structure, comprising: a torsion section coupled to the vehicle, said torsion section having opposite ends; curved sections integrally extending from the respective opposite ends of said torsion section, said curved sections being heat treated to increase the mechanical strength of said curved sections; and arm sections each respectively integrally extending from each of said curved sections and having a free end coupled to a vehicle suspension; at least major portions of said torsion section and said arm sections not being heat treated.
Claim 2
Dependent Claim
95 words
A stabilizer for a vehicle, the stabilizer being a single, one piece, unitary structure, comprising: a torsion section coupled to the vehicle, said torsion section having opposite ends; curved sections integrally extending from the respective opposite ends of said torsion section, said curved sections being heat treated to increase the mechanical strength of said curved sections; and arm sections each respectively integrally extending from each of said curved sections and having a free end coupled to a vehicle suspension; at least major portions of said torsion section and said arm sections not being heat treated.
Claim 3
Dependent Claim
18 words
A stabilizer according to claim 1, wherein said curved sections are heat treated to increase the hardness thereof.
Claim 4
Dependent Claim
19 words
A stabilizer according to claim 2, wherein said curved sections are subjected to a heat treatment which includes tempering.
Claim 5
Dependent Claim
18 words
A stabilizer according to claim 1, wherein said single, one piece, unitary stabilizer structure is a hollow member.
Claim 6
Dependent Claim
18 words
A stabilizer according to claim 1, wherein said single, one piece, unitary stabilizer structure is a solid member.
Claim 7
Dependent Claim
14 words
A stabilizer according to claim 2, wherein said curved sections are high frequency hardened.
