This element () is of the type including a hollow elongate body () made of metal and having a closed section; and a continuous second body () made of plastics material overmolded on the metal first body (), the plastics material second body () including at least two rings () surrounding the metal first body (), the rings () being longitudinally spaced part. In any cross-section of the metal first body (), the plastics material second body () is situated entirely outside the outline of the metal first body (), and the ratio of the axial length of each ring (4) over the longitudinal distance between the rings () is less than 1. The invention is applicable to the front faces of motor vehicles.

Structural element for a motor vehicle, and a method of fabricating such an element

This element () is of the type including a hollow elongate body () made of metal and having a closed section; and a continuous second body () made of plastics material overmolded on the metal first body (), the plastics material second body () including at least two rings () surrounding the metal first body (), the rings () being longitudinally spaced part. In any cross-section of the metal first body (), the plastics material second body () is situated entirely outside the outline of the metal first body (), and the ratio of the axial length of each ring () over the longitudinal distance between the rings () is less than 1. The invention is applicable to the front faces of motor vehicles.

A structural element includes: at least one hollow metallic body () with a closed cross-section, an external surface (), and at least one adhesion lug () formed on the external surface (); and at least one plastic body () which is moulded over the metallic body, covering the external surface () of the metallic body in such a way as to at least partially cover the adhesion lug () in order to connect the plastic body () to the metallic body (). According to one aspect of the invention, the adhesion lug () protrudes over the external surface () of the metallic body (), the adhesion lug () being closed, connected to the metallic body (), and having an undercut () in relation to the external surface () of the metallic body (). The inventive structural element can be applied to the front of motor vehicles.

This structural element comprises a first () and a second () metal member, whose regions () overlap and a reinforcing piece () of plastics material which is overmoulded on the first and second metal members, the reinforcing piece comprising at least a portion () for connecting the metal members. The overlap region () of the first member () comprises at least an anchoring recess () . The overlap region () of the second member () comprises at least a discrete zone () set-back from the second metal member () for securing the plastics material, and the connecting portion () extends into the set-back zone () in order to be engaged in the anchoring recess (). Used, for example, in the construction of front faces.
