Abstract
A resilient, elastomeric jounce bumper is described as having a cylindrical head which protrudes from a larger diameter cylindrical body which has a cylindrical extension which surrounds at least a portion of the head in spaced radial relation, such that an annular void is formed around the head in the area of the body extension. The outer, free annular end of the body extension curves inwardly towards the head and terminates in close proximity to the head to prevent harmful particulate matter from entering the annular void. The body extension is provided with at least one, circular metal ring which is embedded in the extension adjacent the curved end of the extension to restrict radial expansion of the head, when the bumper is place under a heavy load.
