Abstract
Abstract Suspension systems for automotive vehicles of the type employing primary coil suspension springs between the sprung and unsprung masses are adapted for adjustment of the local suspension height and vehicle attitude or trim by including at either or both of the front and rear suspensions lower spring seats having one surface engaged by the lower end of the coil spring and an opposite surface having several pairs of parti-cylindrical seat faces complementary to the supporting axle housing or the like, the seats being rotatable to different orientations on the axle to select different amounts of elevation of the lower end of the spring.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
In vehicle suspension for automotive vehicles including sprung and unsprung masses and a coil primary suspension spring interposed therebetween, said unsprung mass including a tubular axle, a vehicle height adjusting spring seat member mounted rotatably on said axle and interposed between one end of said spring and the outer surface of said tubular axle, said spring seat including a first generally level surface engaging said end of said spring, said spring seat further including an opposite surface engageable with said outer surface of said axle and including at least two pairs of load supporting seat faces each face of each pair being formed complementary to only a portion of said outer surface of said axle, said pairs of seat faces being spaced by predeterminedly different amounts from said first surface of said seat whereby rotation of said seat effecting engagement between a selected one of said pairs of seat faces on said axle effects a selected one of varying amounts of height adjustment of said one end of said spring relative to said axle.
Claim 2
Dependent Claim
174 words
In vehicle suspension for automotive vehicles including sprung and unsprung masses and a coil primary suspension spring interposed therebetween, said unsprung mass including a tubular axle, a vehicle height adjusting spring seat member mounted rotatably on said axle and interposed between one end of said spring and the outer surface of said tubular axle, said spring seat including a first generally level surface engaging said end of said spring, said spring seat further including an opposite surface engageable with said outer surface of said axle and including at least two pairs of load supporting seat faces each face of each pair being formed complementary to only a portion of said outer surface of said axle, said pairs of seat faces being spaced by predeterminedly different amounts from said first surface of said seat whereby rotation of said seat effecting engagement between a selected one of said pairs of seat faces on said axle effects a selected one of varying amounts of height adjustment of said one end of said spring relative to said axle.
Claim 3
Dependent Claim
36 words
The combination recited in claim 1, said tubular axle further including an upstanding pilot defining an axis, said seat member being centrally bored and receiving said pilot for rotation of said seat member about said axis.
Claim 4
Dependent Claim
177 words
In vehicle suspension for automotive vehicles including sprung and unsprung masses and a coil primary suspension spring interposed therebetween, said unsprung mass including a cylindrically tubular axle, a vehicle height adjusting spring seat member mounted rotatably on said axle and interposed between one end of said spring and the outer cylindrical surface of said axle, said spring seat including a first generally level surface engaging said end of said spring, said spring seat further including an opposite surface engageable with said outer tubular surface of said axle and including at least two pairs of load supporting seat faces each face of each pair being formed parti-cylindrical complementary to a portion of said outer cylindrical surface of said axle, said pairs of seat faces being spaced by predeterminedly different amounts from said first surface of said seat whereby rotation of said seat effecting engagement between a selected one of said pairs of seat faces on said axle effects a selected one of varying amounts of height adjustment of said one end of said spring relative to said axle.
Claim 5
Dependent Claim
177 words
In vehicle suspension for automotive vehicles including sprung and unsprung masses and a coil primary suspension spring interposed therebetween, said unsprung mass including a cylindrically tubular axle, a vehicle height adjusting spring seat member mounted rotatably on said axle and interposed between one end of said spring and the outer cylindrical surface of said axle, said spring seat including a first generally level surface engaging said end of said spring, said spring seat further including an opposite surface engageable with said outer tubular surface of said axle and including at least two pairs of load supporting seat faces each face of each pair being formed parti-cylindrical complementary to a portion of said outer cylindrical surface of said axle, said pairs of seat faces being spaced by predeterminedly different amounts from said first surface of said seat whereby rotation of said seat effecting engagement between a selected one of said pairs of seat faces on said axle effects a selected one of varying amounts of height adjustment of said one end of said spring relative to said axle.
Claim 6
Dependent Claim
208 words
In vehicle suspension for automotive vehicles including sprung and unsprung masses and a coil primary suspension spring adapted to be interposed therebetween, said unsprung mass including a road-wheel supporting member, means defining on said supporting member a cylindrical load surface, an upstanding pilot extending from said load surface and defining an axis, a vehicle height adjusting spring seat member centrally bored and receiving said pilot so as to be rotatable thereon about said axis, said seat member being compressively interengaged between one end of said spring and said load surface, said seat member including a first generally level surface engaging said end of said spring, said seat member further including an opposite surface engageable with said load surface and including a plurality of pairs of load supporting seat faces each face of each pair being formed parti-cylindrical complementary to at least a portion of said load surface, said pairs of seat faces being spaced by predeterminedly different amounts from said first surface of said seat member whereby rotation of said seat member effecting engagement between a selected one of said pairs of seat faces on said axle effects a selected one of varying amounts of height adjustment of said one end of said spring relative to said axle.
Claim 7
Dependent Claim
208 words
In vehicle suspension for automotive vehicles including sprung and unsprung masses and a coil primary suspension spring adapted to be interposed therebetween, said unsprung mass including a road-wheel supporting member, means defining on said supporting member a cylindrical load surface, an upstanding pilot extending from said load surface and defining an axis, a vehicle height adjusting spring seat member centrally bored and receiving said pilot so as to be rotatable thereon about said axis, said seat member being compressively interengaged between one end of said spring and said load surface, said seat member including a first generally level surface engaging said end of said spring, said seat member further including an opposite surface engageable with said load surface and including a plurality of pairs of load supporting seat faces each face of each pair being formed parti-cylindrical complementary to at least a portion of said load surface, said pairs of seat faces being spaced by predeterminedly different amounts from said first surface of said seat member whereby rotation of said seat member effecting engagement between a selected one of said pairs of seat faces on said axle effects a selected one of varying amounts of height adjustment of said one end of said spring relative to said axle.
