UNDERRUN PROTECTION STRUCTURE AND METHOD FOR MANUFACTURING AND ASSEMBLING THE SAME.

摘要

The underrun protection structure is for a vehicle having a vehicle chassis frame (2). This underrun protection structure (91) comprises at least one underride guard (12) having an elongated shape and at least two support brackets (23, 24). Each support bracket extends according to a main bracket direction (33) between a first end (25) where is fixed said underride guard (12) and a second end (26) for the fixation of the underrun protection structure (91) under the vehicle chassis frame (2). Each support bracket (23, 24) has a hollow body (27), side walls (28) delimiting said hollow body (27) and inner walls (30) dividing the hollow body (27) into cavities (29). The inner walls (30) and the cavities (29) extend in parallel straight lines inside each support bracket (23, 24) and according to a direction (31) that is transverse to the main bracket direction (33) of the support bracket (23, 24) and that is perpendicular to the underride guard (12).
