Estimating the term…
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.
A bumper for a motor-vehicle having a box-shaped cross-section, comprising an elongated bumper member made of plastics material and having an open cross-section substantially shaped like a "C", said bumper member being closed in the rear by one removable reinforcing wall comprising a substantially rectilinear lamina having at each end one enlargement radiused to the plane of the lamina by means of a slanting plane and provided with transversal holes for a stable anchoring of the reinforcing wall to the bumper member and to the motor-vehicle, said reinforcing wall having along its longitudinal borders first coupling means which are engageable with corresponding second coupling means provided along the opposite longitudinal borders of the bumper member, said first and second coupling means providing a solid joining of the bumper member and reinforcing wall.
