The flap body () and the seal () are made of elastomers. The seal () is joined to the flap body () by a pressure plate () made of a thermoplastic. The control flap may be made by a method that includes: producing the flap body () from a thermoplastic by injection molding; producing the pressure plate () from a thermoplastic by injection molding; producing the seal () from an elastomer by injection molding; introducing the pressure plate () into the undercut () of the seal (); inserting the pressure plate () with the seal () into the recess () of the flap body () and bonding the pressure plate () and flap body ().",
