Abstract:
1. A shock absorber for motor vehicles, comprising: a deforming body comprising a first half shell and a second half shell which are opposite and fixed to one another to form a tubular member having a longitudinal axis, said first half shell and said second half shell each having two fixing tabs or flanges extending along opposite edges of the respective half shell and parallel to said longitudinal axis, the fixing tabs or flanges of said first half shell being juxtaposed and connected to respective ones of the fixing tabs or flanges of the second half shell, the first half shell and the second half shell each further comprising, further to the two fixing tabs or flanges, a plurality of walls which are adjacent to and contiguous with one another along at least one intersection edge extending parallel to said axis, each of said first half shell and said second half shell being formed with at least one energy-absorbing deformation bead extending in a plane oriented perpendicularly to said axis and which extends on all the walls of the plurality of walls and on the fixing tabs or flanges, each said bead including as many bead portions as are the walls of the plurality of walls, said bead portions including at least one first bead portion projecting outwardly away from said axis and at least one second bead portion projecting inwardly toward said axis, the bead portions of said first half shell being coplanar with and opposed to bead portions of said second half shell, said first bead portion and said second bead portion being provided on adjacent ones of said walls and being disposed adjacent to and contiguous with one another at said at least one intersection edge, said bead portions being arranged so that there is alternation between bead portions projecting outwardly from the axis and bead portions projecting inwardly toward said axis, each bead including, in addition to the bead portions formed on the plurality of walls, bead sections formed on the fixing tabs or flanges of each of said first half shell and said second half shell, the bead sections being coplanar and contiguous with at least one bead portion of the respective deformation bead of the respective half shell, the bead sections on the fixing tabs or flanges of one of said first half shell and said second half shell being disposed adjacent to the bead sections on the fixing tabs or flanges of the other of said first half shell and said second half shell, the bead sections on the fixing tabs or flanges of one of said first half shell and said second half shell projecting away from the fixing tabs or flanges of the other of said first half shell and said second half shell.
