ABSTRACT:
A bumper mounting system for a motor vehicle includes a pair of bumper connectors which extend from the vehicle frame to support a bumper bar on their outer ends. Each connector extends substantially parallel with the vehicle longitudinal axis and is resiliently attached intermediate its fore and aft ends to the frame by an elastomeric isolator bracket assembly. The aft end of the connectors are flexibly coupled to the frame by means of a resilient pivotal support. The connectors allow the bumper to serve as a tuned dynamic absorber mass reducing bending amplitude of the vehicle body thereby avoiding undesirable resonant shake of the body structural components such as the floor pan, seats, steering column, wheels etc., during engine idle.
