Abstract
Abstract A resiliently deformable bumper assembly which includes an elastomeric outer shell attached to a rigid backing member. The shell is attached to upper and lower grooves formed in the backing member by means of beads received within the grooves. Each of the beads is formed by a rearward edge portion of the outer shell together with a strip of injected caulking material partially enclosed by the edge portion. The beads are preferably bulbous in cross sectional shape and conform generally to the interior contours of the respective grooves.
