Abstract
Abstract A vehicle suspension mechanism including a carrier for carrying a rear wheel rotatably about an axis of rotation, a strut assembly having an upper end connected with a vehicle body and a lower end connected with the carrier, a swingable arm pivotably connected through resilient rubber bushes with the vehicle body at a longitudinally spaced first forward point and a first rearward point and with the carrier at a longitudinally spaced second forward point and a second rearward point, the first rearward point being at a higher level than a plane defined by the remaining three points so that a toe-in movement is produced when the arm is upwardly swung.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
115 words
A vehicle suspension mechanism including carrier means for carrying a rear wheel rotatably about an axis of rotation, strut means having an upper end connected with a vehicle body and a lower end connected with said carrier means, swingable arm means pivotally connected through resilient means with said vehicle body at a first forward point and a first rearward point, said first forward front spaced longitudinally from said first rearward point, and with said carrier means at a second forward point and a second rearward point, said second forward point spaced longitudinally from said second rearward point, said first rearward point being at a higher level than a plane defined by the remaining three points.
Claim 2
Dependent Claim
115 words
A vehicle suspension mechanism including carrier means for carrying a rear wheel rotatably about an axis of rotation, strut means having an upper end connected with a vehicle body and a lower end connected with said carrier means, swingable arm means pivotally connected through resilient means with said vehicle body at a first forward point and a first rearward point, said first forward front spaced longitudinally from said first rearward point, and with said carrier means at a second forward point and a second rearward point, said second forward point spaced longitudinally from said second rearward point, said first rearward point being at a higher level than a plane defined by the remaining three points.
Claim 3
Dependent Claim
41 words
A vehicle suspension mechanism in accordance with claim 1 in which said resilient means includes a rubber bush provided at each of said first forward and rearward points comprised of an inner and outer tubes connected with a cylindrical rubber element.
Claim 4
Dependent Claim
43 words
