Definitions

  • the part comprises means adapted to be deformed during bending and thus form at least two bosses likely to come into contact if the bending angle exceeds a threshold.
  • FIG. 3 diagrammatically shows a piece provided with bosses according to the present invention, before bending
  • FIG. 6 schematically represents a variant according to the present invention according to which the intervals formed between the bosses are of variable sections along the length of the part
  • FIG. 33 represents the part of FIG. 32 after bending
  • FIG. 36 shows an alternative embodiment of FIG. 35 in which the bosses are formed in the bottom of longitudinal grooves formed on an outer face of the part
  • FIG. 43 represents a sectional view of a part according to a variant of implantation of the bosses, before bending,
  • Figure 52 shows a top view of the part of Figure 51 after bending.
  • Figure 17 which shows a top view of a part according to Figure 15 or 16 after bending, illustrates the cooperation defined between the tops of the bosses to limit bending.
  • FIG. 42 illustrates the possibility of arranging the bosses on a wall 133 or 134 of a part, for example according to FIG. 39.
