A bumper for motor vehicles with a cross bearer at least indirectly supported at the vehicle frame and constructed essentially as closed hollow profile and with an elastically yielding impact-absorbing profile member essentially U-shaped in cross section which is detachably and form-lockingly secured at the cross bearer on the impact-endangered side thereof; the U-shaped profile is thereby clamped with its leg ends over its entire length between web-like mounting edges extending in the longitudinal direction of the cross bearer, on the one hand, and corresponding lateral web-like mounting edges of a clamping bar also extending in the longitudinal direction and secured to the cross bearer, on the other; the web-like mounting edges of the cross bearer extend at least approximately perpendicularly to the legs of the U-shaped profile member and engage in corresponding longitudinal grooves of the U-shaped profile member provided on the inside of the leg ends; the clamping bar which is constructed as bearer channel surrounding the cross bearer on the backside thereof and which is stabilized together with the same in its cross-sectional shape, presses with its lateral longitudinal edges the leg ends of the U-shaped profile externally against the cross bearer. |
