Weather strip and fixing structure of same

Abstract

A weather strip of the present invention includes a molded portion including a base having at least one hole. The weather strip also includes a seal portion, which extends from the base and has a hollow region and at least one protrusion formed at an inside of a side wall of the seal portion. Each protrusion is locally formed corresponding to a position of each hole of the base. The weather strip includes a clip, which is inserted into the hole in the base, used for fixing the base to a vehicle door. The protrusion prevents the clip from rotating in the hollow region of the seal portion.

1 . A vehicle door weather strip, comprising: 
 a molded base defining at least one attachment hole therein; and    a seal portion extending from the base and defining a hollow region therein, the seal portion including at least one clip rotation prevention protrusion formed inside of the hollow region and adjacent to the base.    
   
   
       2 . A weather strip according to  claim 1 , wherein the at least one protrusion is located corresponding to a position where the attachment hole is located.  
   
   
       3 . A weather strip according to  claim 1 , wherein the at least one protrusion is continuously formed along a side wall of the seal portion that defines the hollow region.  
   
   
       4 . A weather strip according to  claim 1 , further comprising a clip for fixing the base to a vehicle body through the attachment hole and including a horizontally elongated clip head, a clip neck clip neck that has a smaller diameter than the length of the clip head and a clip leg that is inserted into a fixing hole of the vehicle body.  
   
   
       5 . A weather strip according to  claim 1 , further comprising a clip for fixing the base to a vehicle door through the attachment hole and including a horizontally elongated clip head, a clip neck clip neck that has a smaller diameter than the length of the clip head and a clip leg that is inserted into a fixing hole of the vehicle door.  
   
   
       6 . A weather strip according to  claim 2 , wherein the at least one protrusion is formed along only one side wall of the seal portion that defines the hollow region.  
   
   
       7 . A weather strip according to  claim 4 , wherein the at least one protrusion has a predetermined height to prevent rotation of the clip head.  
   
   
       8 . A weather strip according to  claim 1 , wherein the hollow region of the seal portion is defined by a pair of side walls and a half-arc wall connecting the pair of side walls.  
   
   
       9 . A vehicle door weather strip, comprising: 
 extruded portions for sealing a vehicle door; and    molded portions each integrated with one end of each of the extruded portions for sealing the vehicle door; wherein the molded portions include a molded base with at least one attachment hole defined therein, a seal portion extending from the base and including a hollow region defined therein, and a protrusion formed within the hollow region adjacent to the base.    
   
   
       10 . A fixing structure of a vehicle weather strip, comprising: 
 a molded base defining at least one attachment hole;    a seal portion extending from the molded base and definig a hollow region therein;    a clip for fixing the molded base to a vehicle door through the attachment hole and including a horizontally elongated clip head that is located in the hollow region, a clip neck that has a smaller diameter than the length of the clip head and a clip leg that is inserted into a fixing hole of the vehicle door; and    a protrusion formed inside the hollow region and adjacent to the base, wherein the clip rotation prevention protrusion prevents the clip head from rotating in the hollow region of the seal portion.
