Abstract
A jounce bumper assembly can be used in a suspension system for an automotive vehicle. The assembly can contain a jounce bumper having a longitudinal axis, a bottom portion, and a tip portion spaced apart from the bottom portion in the axial direction, where the jounce bumper is resiliently deformable between an uncompressed basic state and an axially compressed state. The assembly can also contain a support member for supporting the jounce bumper, the support member having a wall section which can be arranged around the bottom portion and resiliently deformable with the jounce bumper in the axial and radial direction. The assembly can further contain at least one stiffening element associated to the wall section and configured to locally limit the radial deformation of the support member.

A jounce bumper assembly for use in a suspension system for an automotive vehicle, comprising:
- a jounce bumper having a longitudinal axis, a bottom portion, and a tip portion spaced apart from the bottom portion in an axial direction, wherein the jounce bumper is resiliently deformable between an uncompressed basic state and an axially compressed state,
- a support member for supporting the jounce bumper, the support member having a wall section which is arranged around the bottom portion, wherein the support member is resiliently deformable with the jounce bumper in the axial direction and a radial direction, and
- at least one stiffening element associated to the wall section and configured to locally limit a radial deformation of the support member,
- wherein the wall section of the support member has a rim portion, and the at least one stiffening element is arranged proximal to the rim portion,
- wherein the support member has a stop shoulder extending radial inwardly and/or radial outwardly from the rim portion, and
- wherein the at least one stiffening element has a sleeve portion extending in the axial direction and a stop portion extending parallel to the stop shoulder.
