1. A sealing profile (1) for embedding into a moulded part (50) made of curable material, wherein the sealing profile (1) comprises a profile body (2), with
a) a profile base (3) to be embedded within the moulded part (50), which, after embedding the sealing profile (1), comprises a profile base face (5) that faces the moulded part (50); and lateral profile base flanks (7), and
b) a profile back (4) projecting from the profile base (3) which comprises a profile-back face (6) opposite the profile base face (5) and lateral profile-back flanks (8),
and wherein,
the sealing profile (1) has at least one anchoring foot (9) projecting from the profile base face (5), and
the profile base flanks (7) merge into the profile base face (5) with rounded portions (10) or chamfers (21),
wherein the rounded portions (10) run in the cross-section of the sealing profile (1) from a first transition point (16) in a curved line to a central profile axis (11) perpendicular to the profile base face (5) and, at a second transition point (17), merge into the profile base face (5), or the chamfers (21) run in the cross-section of the sealing profile (1) from a first transition point (16) in a polygonal line to a central profile axis (11) perpendicular to the profile base face (5) on the profile base face (5), and merge into the profile base face (5) at a second transition point (17).
