Spring isolator for a motor vehicle suspension

An isolator for a suspension system including a coil spring comprising:

• a first surface for supporting said isolator relative to a base structure;
• a second surface for engaging said coil spring;
• and
• a projection on said first surface for orienting said isolator relative to said base structure by interfering with a recessed surface of said base structure.

An isolator for a suspension system including a coil spring comprising:

• a first surface for supporting said isolator relative to a base structure;
• a second surface for engaging said coil spring;
• a third surface extending between said first surface and said second surface, said third surface including at least one notch formed therein;
• and
• an orientation member on said second surface for orienting said coil spring relative to said second surface.

An isolator for a suspension system including a coil spring comprising:

• a first surface for supporting said isolator relative to a base structure;
• a second surface for engaging said coil spring;
• and
• a plurality of protrusions extending about a perimeter of said second surface so as to overlap a lower coil of said coil spring for securing said coil spring to said second surface.

An isolator for a suspension system including a coil spring comprising:

• a first surface for supporting said isolator relative to a base structure;
• a second surface for engaging said coil spring;
• and
• at least one notch formed in said second surface for interrupting a vibration path between said first surface and said coil spring.

A suspension mechanism for a motor vehicle comprising:

• an axle;
• a spring seat coupled to said axle, said spring seat including an aperture formed therein;
• an isolator disposed on said spring seat, said isolator including a first projection extending therefrom engaging said aperture of said spring seat such that said isolator has a pre-selected orientation relative to said spring seat, said isolator also including at least one notch formed therein for interrupting a path for vibrations through said isolator;
• and
• a coil spring coupled to said isolator by a retention member, said coil spring having an end engaging a second projection extending from said isolator such that said coil spring has a pre-selected orientation relative to said isolator.
