Abstract

The invention relates to a crash structure (10a, 10b, 10c, 10d, 10e, 10f) for a motor vehicle, having a crash element (12a, 12b, 12c, 12d, 12e, 12f), which is made at least partially of a fiber composite material, and a support unit (16a, 16b, 16c, 16d, 16e, 16f) having at least one support element (14a, 14.1b, 14.2b, 14c, 14d, 14e, 14f) and being connectable to a load-bearing structure (18) of the motor vehicle. According to the invention, the crash element (12a, 12b, 12c, 12d, 12e, 12f) is made of an undulated component with waves (22) in the vehicle longitudinal direction (20) and an end region (24) which is supported on the load-bearing structure (18) of the motor vehicle at least via the at least one support element (14a, 14.1b, 14.2b, 14c, 14d, 14e, 14f) of the support unit (16a, 16b, 16c, 16d, 16e, 16f) in the vehicle transverse direction (26).
