Abstract: The invention relates to an assembly for an aircraft comprising an aircraft wall in which a routing slit is formed, a drive shaft of a bearing surface that passes through the slit while remaining free to move along the slit, and a seal to seal this slit. According to the invention, the seal is formed in two parts, comprising a lower seal part and an upper seal part arranged facing each other on opposite sides of the slit, each of the two parts comprising a lip forming contact tracks between which the drive shaft is squeezed and moves while deforming them during a phase in which the bearing surface is moved, these lips being in the shape of rabbit ears so that they can wind around the shaft so as to limit parasite opening spaces, and to prevent misalignment.
