Elastomeric and plastics materials are used in a variety of components which are designed to protect automobiles and their occupants from damage or injury during impacts. Such components may also afford some pedestrian protection. The use of rubber in various modes of deformation provides the designer of bumper systems with a range of force/deflection characteristics with which to work. In general, impact-absorbing bumpers are either rigid bars mounted on resilient supports or bumpers made of an elastomeric material along their entire length. An example of the former type employs rubber shear mountings. For the latter type, in which complete soft front-ends may be included, specific physical properties are required of the rubber used. Stiff natural rubber compounds are being developed for these applications. The paintability of rubber is also an improtation consideration. (a) /TRRl/
