Abstract
A vehicle suspension system including a pair of spring seat retainers. One of the spring seat retainers includes a flange and a pocket portion extending from the flange to a distal rim. A jounce bumper is mounted to the pocket portion of the spring seat retainer and extends from the rim. A band encircles the rim for preventing deformation of the rim upon compression of the jounce bumper.
Claims37
A spring seat retainer comprising:
- a flange extending radially from a central axis;
- a pocket portion extending axially from said flange along said central axis to a distal rim with said distal rim encircling said pocket portion and defining a cavity between said distal rim and said flange for securing a jounce bumper within said cavity;
- said flange and said pocket portion being formed of a homogeneous polymeric material having a first modulus of elasticity;
- a band formed of a metallic material having a second modulus of elasticity greater than said first modulus of elasticity with said band encircling said rim of said pocket portion for preventing bulging of said rim upon exertion of radial forces by the jounce bumper;
- said rim defines a distal end, an inner surface and an outer surface with said outer surface defining a recess extending axially from said distal end to a shoulder and said band presents spaced edges and is disposed in said recess with one of said edges abutting said shoulder.

A spring seat assembly comprising:
- a spring seat retainer having a base and a pocket portion extending axially from said base to a distal rim defining a cavity with said distal rim encircling said cavity and said pocket portion including a stem disposed between said distal rim and said base to define a bottom of said cavity;
- a securing device extending from said distal rim into said cavity above said stem;
- a jounce bumper mounted to said pocket portion within said cavity by said securing device and extending from said distal rim for exerting radial forces within said cavity against said rim;
- and
- a restrictor abutting at least a portion of said distal rim of said pocket portion for preventing deformation of said rim upon the exertion of radial forces by said jounce bumper to retain said jounce bumper in said cavity with said restrictor including a band encircling said rim for preventing bulging of said rim under said band.

A spring seat assembly comprising:
- a spring seat retainer having a base and a pocket portion extending axially from said base to a distal rim defining a cavity with said distal rim encircling said cavity and said pocket portion including a stem disposed between said distal rim and said base to define a bottom of said cavity;
- a securing device extending from said distal rim into said cavity above said stem;
- a jounce bumper mounted to said pocket portion within said cavity by said securing device and extending from said distal rim for exerting radial forces within said cavity against said rim;
- and
- a restrictor abutting at least a portion of said distal rim of said pocket portion for preventing deformation of said rim upon the exertion of radial forces by said jounce bumper to retain said jounce bumper in said cavity;
- wherein said rim defines a distal end, an inner surface and an outer surface with said outer surface defining a recess extending axially from said distal end to a shoulder and said restrictor presents spaced edges and is disposed in said recess with one of said edges abutting said shoulder.
