Abstract
The invention concerns a bumper or front piece for motorvehicles, consisting of a bumper or the like of an open cross-section, substantially C-shaped, closed on the rear in a removable way by a reinforcing plate or wall of varying thickness, consisting of a substantially straight lamina having at its opposite ends at least one enlargement radiused through a slanting plane to said lamina and being provided with suitable means for the steady anchoring of the whole reinforcing piece to the bumper itself, so as to obtain a reinforcing wall of such a shape or profile as to effectively oppose flectional and shearing stresses on the supports, said reinforcing wall having along its longitudinal edges elastic coupling means with suitable gains, with other means provided along the longitudinal edges of the bumper, so as to achieve a mechanical coupling capable of ensuring the solidarity between the jointed parts and contemporaneously to resist longitudinal tangential stresses.
