<p>A vehicle panel (1) in which a curved member (2) is arranged to define a concave surface (3) from which extend major fins (4) and subsidiary fins (5), these major fins (4) and subsidiary fins (5) being interleaved. The major fins (4) have a tongue configuration extending from the curved surface (3) such that there is a gap either side with two opposed edges (9,10) of the curved member (2) in order to facilitate deformation particularly under perpendicular presentations of impact load to the vehicle panel (1). The subsidiary fins (5) only extend partially into the curved surface (3) in order to limit the degree of reinforcement provided by the subsidiary fins (5) which extend directly from one of the opposed edges (9). In such circumstances, the major fins (4) and the subsidiary fins (5) act in concert in order to allow appropriate energy absorption over a wide range of impact load angular presentations to the vehicle panel (1). <IMAGE></p> |
