Crash management system for a motor vehicle

A crash management system (100) for a motor vehicle, the crash management system (100) comprising a crossbeam (10;

• 10a to 10g) for being connected to a body shell structure of the motor vehicle, the crossbeam (10;
• 10a to 10g) comprising a front flange (16;
• 26e), a rear flange (14;
• 14d) and at least two transverse walls (18, 20;
• 20c) connecting the front flange (16;
• 26e) to the rear flange (14;
• 14d) in order to form a closed cross section of the crossbeam (10;
• 10a to 10e), at least one partition wall (26;
• 26a to 26d;
• 26f;
• 26g) extending at least approximately parallel to the front flange (16;
• 26e) and/or to the rear flange (14;
• 14d) being disposed between the front flange (16;
• 26e) and the rear flange (14;
• 14d) the crash management system (100) also comprising at least one dividing wall (28;
• 28b;
• 28f;
• 35;
• 35f, 36;
• 36b;
• 36f, 53;
• 59a to 59d;
• 64a to 64f) protruding from the front flange (16;
• 26e) or the rear flange (14;
• 14d) in the direction of the at least one partition wall (26;
• 26a to 26d;
• 26f;
• 26g) and being connected to the at least one partition wall (26;
• 26a to 26d;
• 26f;
• 26g) at a joint (44, 46, 48;
• 52;
• 57;
• 61;
• 65;
• 79 to 81), said dividing wall (28;
• 28b;
• 28f;
• 35;
• 35f;
• 36;
• 36b;
• 36f, 53;
• 59a to 59d;
• 64a to 64f) separating two closed chambers (32, 34, 38, 40, 42;
• 49, 51;
• 55, 56;
• 58a to 58f, 60a to 60c;
• 62a to 62e;
• 72, 74, 76, 78;
• 85, 86) from one another within the cross section of the crossbeam (10;
• 10a to 10g), at least one, preferably all joints (44, 46, 48;
• 52;
• 57;
• 61;
• 65;
• 79 to 81) being disposed in the range between 30% and 70% of the height (h1 to h7) of the chamber (32, 38, 40, 42;
• 49, 51;
• 55, 56;
• 58a to 58f, 60a to 60c;
• 62a to 62e;
• 72, 74, 76, 78;
• 85, 86) in the direction of the front flange 16;
• 26e) or of the rear flange (14;
• 14d) in relation to a chamber (32, 38, 40, 42;
• 49, 51;
• 55, 56;
• 58a to 58f, 60a to 60c;
• 62a to 62e;
• 72, 74, 76, 78;
• 85, 86) disposed on a side of the partition wall (26;
• 26a to 26d;
• 26f;
• 26g) opposite the at least one joint (44, 46, 48;
• 52;
• 57;
• 61;
• 65;
• 79 to 81), characterized in that a neutral axis (NF) of the area cross section of the crossbeam (10;
• 10a to 10g) is disposed in the range between 20% and 45% of the depth (T) of the crossbeam (10;
• 10a to 10g) in a direction (X) extending from the rear flange (14;
• 14d) in the direction of the front flange (16;
• 26e).
