Abstract:
1. An energy absorption device for an automobile seat of an automobile in case of a shock, said device having substantially the form of a plate having a succession of cutouts following each other in a deformation direction between a first cutout and a last cutout and defining between them a plurality of bridges extending in a stretching direction transverse to the deformation direction, wherein: the first cutout has a shape flaring in the deformation direction, in the direction of the following cutouts, the first cutout is separated from a second cutout which follows the first cutout according to the deformation direction by a first bridge, said first bridge having a first edge extending substantially in a transverse direction between two ends and delimiting the first cutout, and the first cutout is furthermore delimited by two flaring edges each extending substantially in the deformation direction to a front end by which each flaring edge is connected to one of the ends of said first edge, and flaring edges forming between them a flaring angle (α) between 10 degrees and 40 degrees, in the stretching direction, the first cutout has between the front ends of the flaring edges a width that is substantially equal to the width of the other cutouts, and all of the bridges have a striction reducing their width in the deformation direction at each of their ends in the stretching direction.
