Claim 6

An independent rear wheel suspension as defined in claim 3 further comprising: a spring seat integrally formed with one of said front and rear control arms; said spring seat seating a spring interposed between said spring seat and said chassis.

Claim 7

An independent rear wheel suspension for a vehicle comprising: a chassis; a wheel support support member adapted to rotatably mount a wheel; an upwardly extending telescopic shock absorber having its lower end rigidly secured to said wheel support member; means pivotably connecting the upper end of said shock absorber to said chassis; a first transversly extending control arm pivotably connected at its inboard end to said chassis and at its outboard end to said wheel support member; a second transversely extending control arm positioned in front of said first control arm and pivotably connected at its inboard end to said chassis and at its outboard end to said wheel support member; one of said transversely extending control arms having its inboard end connected by two longitudinally spaced resilient bushings to said chassis; said two longitudinally spaced resilient bushings constructed to control the amount of wheel recession allowed for a given recessive force; said two longitudinally spaced bushings being constructed to allow said one control arm to pivot about a vertical axis as said wheel recesses to control in conjunction with said other arm the toe angle of said wheel as said wheel recesses.

Claim 8

An independent rear wheel suspension for a vehicle comprising: a chassis; a wheel support support member adapted to rotatably mount a wheel; an upwardly extending telescopic shock absorber having its lower end rigidly secured to said wheel support member; means pivotably connecting the upper end of said shock absorber to said chassis; a first transversly extending control arm pivotably connected at its inboard end to said chassis and at its outboard end to said wheel support member; a second transversely extending control arm positioned in front of said first control arm and pivotably connected at its inboard end to said chassis and at its outboard end to said wheel support member; one of said transversely extending control arms having its inboard end connected by two longitudinally spaced resilient bushings to said chassis; said two longitudinally spaced resilient bushings constructed to control the amount of wheel recession allowed for a given recessive force; said two longitudinally spaced bushings being constructed to allow said one control arm to pivot about a vertical axis as said wheel recesses to control in conjunction with said other arm the toe angle of said wheel as said wheel recesses.

Claim 13

An independent rear wheel suspension for a vehicle comprising: a chassis; a wheel support member with an attached road wheel; transversely extending front and rear control arms pivotably connected at their inboard ends to said chassis and at their outboard ends to said wheel support member; one of said control arms being connected to said chassis through front and rear longitudinally spaced resilient bushings; said longitudinally spaced bushings being of different relative stiffness so as to allow the control arm to which they are attached to pivot about a vertical axis as said wheel support member recesses so as to control in conjunction with said other transversely extending arm the toe angle of said road wheel.

Claim 14

An independent rear wheel suspension for a vehicle comprising: a chassis; a wheel support member with an attached road wheel; transversely extending front and rear control arms pivotably connected at their inboard ends to said chassis and at their outboard ends to said wheel support member; one of said control arms being connected to said chassis through front and rear longitudinally spaced resilient bushings; said longitudinally spaced bushings being of different relative stiffness so as to allow the control arm to which they are attached to pivot about a vertical axis as said wheel support member recesses so as to control in conjunction with said other transversely extending arm the toe angle of said road wheel.

Claim 15

The independent rear wheel suspension as claimed in claim 8 wherein said front arm is connected by said front and rear longitudinally spaced resilient bushings, said front bushing being of greater stiffness than said rear bushing whereby said front arm is allowed to pivot about a vertical axis during wheel recession in cooperation with said rear arm and said wheel support so as to urge said road wheel to toe in.

Claim 16

The independent rear wheel suspension as claimed in claim 8 wherein said front arm is connected by said front and rear longitudinally spaced resilient bushings, said front bushing being of lesser stiffness than said rear bushing whereby said front arm is allowed to pivot about a vertical axis during wheel recession in cooperation with said rear arm and said wheel support so as to urge said road wheel to toe out.

Claim 17

The independent rear wheel suspension as claimed in claim 8 wherein said rear arm is connected by said front and rear longitudinally spaced resilient bushings, said front bushing being of lesser stiffness than said rear bushing whereby said rear arm is allowed to pivot about a vertical axis during wheel recession in cooperation with said front arm and said wheel support so as to urge said road wheel to toe in.

Claim 18

The independent rear wheel suspension as claimed in claim 8 wherein said rear arm is connected by said front and rear longitudinally spaced resilient bushings, said front bushing being of greater stiffness than said rear bushing whereby said rear arm is allowed to pivot about a vertical axis during wheel recession in cooperation with said front arm and said wheel support so as to urge said road wheel to toe out.

Claim 19
