A flexible, pneumatic bumper adapted for motor vehicle applications. A plurality of individual chambers are defined by a resiliently deformable outer bumper shell, a supporting plate secured to the vehicle structural members and a plurality of baffles or separator elements extending from the bumper shell toward or to the mounting plate. When the outer bumper shell is displaced inwardly due to an impact force, resultant chamber deformation causes an increase in chamber pressure that is relieved by air being forced out of the chamber to an adjacent chamber or to the atmosphere through a pressure relief valve. Following impact, return of the bumper shell to its original shape is slowed by a restricted return air flow into the chambers thereby preventing bumper rebound forces.
