Motor vehicle deformable front wing has inner sealing partition with break line created by series of blind holes

摘要

The front wing (10), designed to collapse on impact, consists of an outer wall (12) adjoining the engine bonnet (14) and an inner sealing partition (24) between its inner edge (20) and the chassis (22). The sealing partition comprises upper (42) and lower (44) sections separated by a break line (46) formed by a row of blind holes in a transverse rib. The break line allows the two sections (42, 44) to displace relative to one another in the event of impact that collapses an inner Z-shaped wall (40).
