ABSTRACT:
The present invention provides a rate stiffening jounce bumper assembly, including a cup member having a large-headed mushroom stud which is inserted into the cup-shaped member and overmolded with an elastomeric bumper material. The head portion of the mushroom stud forms a shelf against which the bumper material is compressed such that the head portion effectively shortens the bumper spring thereby providing a stiffer spring rate to be obtained with a taller jounce bumper assembly.
