  • adjusting screws ZES1, ZES2, ZES3, HES1, HES2, HES3 asuge softe adjusting elements of the Einstelldreiecke EDS1, EDS2, which for engaging the mechanical and / or electromotive actuating means of the Einstelldreieck-systems EDS1, EDS2 and for connecting the main and auxiliary carrier with the support frame are set up.
  • Each adjusting screw has a threaded section GA and a ball head KK.
  • the passage openings of the support frame and the additional support each have a counter-threaded portion, which are adapted to cooperate with the threaded portions of the corresponding adjusting screws and on the one hand to connect the main and / or the additional support to the support frame and on the other hand, the position of the main and / or the additional carrier with respect to the support frame, as it is known from Fig. 6 is apparent.
  • the threaded portions of the (three) adjusting screws HES1, HES2, HES3 are arranged in the designated (three) ports of the support frame TR such that the threaded portions of the adjustment screws into the mating thread portions of the support frame corresponding thereto attack.
  • the ball head engages ever an adjusting screw in the corresponding adapted to receive a ball head receiving socket of the main wearer, as in Fig. 6 is shown.
  • the threaded portions of the (three) adjusting screws ZES1, ZES2, ZES3 are arranged in the provided (three) passage openings of the additional support ZT such that the threaded portions of the adjusting screws engage in the corresponding counter-threaded portions of the additional carrier ZT, wherein the ball head each engages an adjusting screw in the corresponding receiving socket adapted for receiving a ball socket of the support frame, as in Fig. 6 is shown.
