Support part with fixing pin

Abstract

In the case of a support part ( 3 ) having at least one locating hole ( 2 ) in which a fixing pin ( 1 ) is captively arranged, the latter has a bottom insertion section ( 1 c ) and a center shank section ( 1 b ) and also a top retaining section ( 1 a ) with a number of retaining teeth ( 12, 13 ) of different length, at least one comparatively long retaining tooth ( 12 ) overlapping the hole edge ( 15 ) of the locating hole ( 2 ) at the top and at least one comparatively short retaining tooth ( 13 ) undercutting the hole edge ( 15 ) on the underside.

         7 . The support part as claimed in one of  claims 1  to  6 , characterized by a cylindrical shank section ( 1   b ) of the fixing pin ( 1 ) extending between the retaining section ( 1   a ) and the insertion section ( 1   c ).  
     
     
         8 . The support part as claimed in one of  claims 1  to  7 , characterized in that the insertion section ( 1   c ) of the fixing pin ( 1 ) is designed to be elastic.  
     
     
         9 . The support part as claimed in one of  claims 1  to  8 , characterized in that the insertion section ( 1   c ) of the fixing pin ( 1 ) is recessed over its section length while push-in arms ( 20 ) are formed.  
     
     
         10 . The support arm as claimed in one of  claims 1  to  9 , characterized in that the insertion section ( 1   c ), at the end, has a bevel ( 19 ) directed inward.  
     
     
         11 . The support part as claimed in one of  claims 1  to  10 , characterized in that the fixing pin ( 1 ), on the circumference, has at least one prominence ( 18 ) for enlarging the pin diameter (D).  
     
     
         12 . The support part as claimed in one of  claims 1  to  11 , characterized in that the fixing pin ( 1 ) is designed as a one-piece sleeve.  
     
     
         13 . The support part as claimed in one of  claims 1  to  12 , characterized in that the fixing pin ( 1 ) has a continuous longitudinal slot ( 24 ) running in the axial direction.  
     
     
         14 . The support part as claimed in one of  claims 1  to  13 , characterized in that the fixing pin ( 1 ) is held with radial clearance ( 22 ) and/or axial clearance in the locating hole ( 2 ).  
     
     
         15 . The support part as claimed in  claim 13 , characterized in that the comparatively long retaining teeth ( 12 ) are angled outward in such a way that said retaining teeth ( 12 ) bear against the hole edge ( 15 ) of the locating hole ( 2 ).
