  • This is with one during, for example Chipless shaping generated, circular in cross section Cup-shaped projection 14 provided, which is in the heat insulation material 12 extends and which in the center of their closed-walled Cup bottom 15 is a substantially conical centering aid 16 having.
  • the cup-like molding 14 is formed on its closed-walled Shell surface 17 with a serving as a so-called backing part Reinforcing body 20 provided.
  • This is essentially in the form of a Circular cylinder formed and with a hollow pin-like receiving section 21 provided whose receiving opening 22 is circular in cross section Casing surface 17 of the cup-like projection 14 engages.
  • the receiving opening 22 of the receiving section 21, which is designed in the form of a hollow pin, is from resilient tongues 23 serving as wall sections of the hollow pin bounded by 90 ° to each other, along the Shell surface of the hollow spigot cuboid-like recesses 24 in the jacket wall of the hollow pin are generated and an annular sector-like Have cross-section.
  • the resilient tongues 23 are at their free, as Tongue tip serving end with two spaced apart, radial extending stop elements 25, which with their outer, from the receiving portion 21 facing stop surface 26 was in Montagezu of the reinforcing body 20 on that facing the heat insulation layer 12 Support the outside of the inner lining 13 and thus the correct position Signal the end position during the assembly process of the reinforcement body 20.
  • the resilient tongues 23 are with their tongue root on one, on the receiving portion 21 adjoining fastening section 27 (see see Fig.
  • the fastening section 27 has a blind hole extending along its center longitudinal axis 29 30, whose longitudinal axis running through its center as that through the Center of the receiving portion 21 extending longitudinal axis with the Center longitudinal axis 29 of the fastening portion 27 coincides.
  • the Blind hole 30 serves as a core hole for self-tapping trained, circular cylindrical screw 31, which for fixing a Cooling air duct 32 is used on the inner lining 13 (see Fig. 1).
  • the cooling air duct 32 is for the purpose of attachment to the inner panel 13 with a stepped fastening cross-section 33 which is circular in cross section provided, the nozzle section reduced in cross section by the paragraph 34 for guiding and supporting the cooling air duct 32 within the cup-like projection 14 is arranged and one on the outer diameter the mounting screw 31 has adapted passage bore 35.
  • the nozzle section 34 having the through bore 35 is a reference this is enlarged in its cross section nozzle section 36 upstream, which is provided with a receiving bore 37, within which is the screw head of the fastening screw 31 in the fastening state the cooling air guide 32 is arranged and which on its from End facing away from the nozzle section 34 can be covered with a cover cap 38 is.
  • the attachment piece 33 is to increase its stability on its outer surface with its shorter nozzle section 36 overlapping up to longer support section 34 provided supporting ribs 39, which are arranged at equal angular intervals of 90 ° to one another.
  • the reinforcing body 20 is in one piece in the present exemplary embodiment made of plastic injection molding, the in the fastening section 27 molded blind hole 30 already during the spraying process is made. It differs from the present exemplary embodiment also possible, the cup-like molding 14 on its lateral surface 17 in their Equip longitudinal ribs running in the axial direction, which form-fitting with provided on the receiving section 21 serving as receiving grooves Exemptions 24 are able to cooperate, as a result of which the reinforcing body 20 in addition to its non-positive bracket, also non-rotatable in and against the direction of insertion of the fastening screw 31 on the Cup-like projection 14 is set.
  • reinforcing body 20 opposes each other the shown and described embodiment of several reinforcing bodies 20 composes, each one for itself accordingly Arranged cup-like molding 14 can be applied, so that one Reinforcement body in and without twisting without additional measures against the direction of insertion of the fastening screw 31 on the inner lining 13 is held.
