  • the anchoring feet 9 in this embodiment originate from an area of the profile base surface 5, above which a solid web 18 made of elastomeric material and extending between hollow longitudinal channels perpendicularly through the profile base 3 is formed.
  • the rounded corners and the inwardly offset anchoring feet 9 are particularly advantageous in order to avoid or reduce the flaking observed in sealing profiles 101 from the prior art.
  • a sealing profile 1 is shown here by way of example, which in this illustration has a bevel 21 made of two individual chamfers in cross section on the left and a bevel 21 made of three individual chamfers in cross section on the right.
  • the transition point 16 on the profile base flank 7 is connected to the transition point 17 on the profile base surface 5 in cross section by a polygon of two linear lines, in the bevel shown on the right the transition points 16 are , 17 connected by a polygon consisting of three linear sections.
  • the sealing profile 1 has different configurations of the corners, for example a different number of chamfers or a chamfer on one side and a rounding on the other side. However, it is preferred if both sides (viewed in cross section) are designed symmetrically to one another.

Abstract

L'invention concerne un profilé d'étanchéité (1) destiné à être intégré dans une pièce moulée (50) en matériau durcissable, grâce à quoi le risque d'écaillage sur la pièce moulée (50) est réduit. Le profil d'étanchéité (1) selon l'invention présente un corps profilé (2), ayant a) une base profilée (3) à incorporer dans la pièce moulée (50), ladite base profilée (3), après que le profil d'étanchéité (1) a été incorporé, ayant une face de base profilée (5) faisant face à la pièce moulée (50) et des flancs de base profilés latéraux (7), et b) un dos de profil (4) qui fait saillie par rapport à la base profilée (3) et présente une face arrière profilée (6) sur le côté opposé à la face de base profilée (5) et des flancs arrière de profil latéral (8), et le profil d'étanchéité (1) présentant au moins un pied d'ancrage (9) faisant saillie de la face de base profilée (5), et les flancs de base profilés (7) passant dans la face de base profilée (5) par l'intermédiaire de parties arrondies (10) ou de parties chanfreinées (21).
