Tension adjustable membrane or mesh seat assembly

Abstract

A seat assembly for a motor vehicle includes a seat frame having a front member, a rear member, and side members extending between the front and rear members. The seat assembly also includes a trim cover material extending in tension over the seat frame and including a perimeter edge disposed about the front, rear, and side members thereof. The trim cover material includes a pocket formed along its perimeter edge. A tensioning mechanism includes a cable having a middle portion and cable ends extending out of the pocket. The tensioning mechanism further includes a tension block having opposing adjustment arms each coupled to one of the cable ends. Movement of the opposing adjustment arms towards and away from each other selectively adjusts the tension in the trim cover material disposed about the seat frame.

1 . A seat assembly for a motor vehicle, said seat assembly comprising: 
 a seat frame having a front member, a rear member, and side members extending between said front and rear members;    a trim cover material extending in tension over said seat frame and including a perimeter edge disposed about said front, rear, and side members thereof, said trim cover material including a pocket formed along said perimeter edge; and    a tensioning mechanism including a cable having a middle portion disposed within said pocket of said trim cover material and cable ends extending out of said pocket, said tensioning mechanism further including a tension block having opposing adjustment arms each coupled to one of said cable ends such that movement of said opposing adjustment arms towards and away from each other selectively adjusts the tension in said trim cover material disposed about said seat frame.    
   
   
       2 . A seat assembly as set forth in  claim 1  wherein said tension block includes a body portion having oppositely facing threaded bores.  
   
   
       3 . A seat assembly as set forth in  claim 2  wherein each of said adjustment arms includes a threaded shaft rotatably engaging said threaded bores for moving said adjustment arms relative to said body portion.  
   
   
       4 . A seat assembly as set forth in  claim 3  wherein said pocket includes a pair of openings for receiving said cable therethrough.  
   
   
       5 . A seat assembly as set forth in  claim 4  wherein each of said adjustment arms includes a hook coupled to one of said cable ends.  
   
   
       6 . A seat assembly for a motor vehicle, said seat assembly comprising: 
 a seat frame having a front member, a rear member, and side members extending between said front and rear members;    a trim cover material extending in tension over said seat frame and including a perimeter edge disposed about said front, rear, and side members thereof, said trim cover material including a pocket formed along said perimeter edge; and    a tensioning mechanism including a cable having a middle portion disposed within said pocket of said trim cover material and cable ends extending out of said pocket, said tensioning mechanism further including a tension block having a body portion, said body portion having opposing adjustment arms each including hooks for coupling to said cable ends such that movement of said opposing adjustment arms towards and away from each other selectively adjusts the tension in said trim cover material disposed about said seat frame.    
   
   
       7 . A seat assembly as set forth in  claim 6  wherein said body portion includes oppositely facing threaded bores.  
   
   
       8 . A seat assembly as set forth in  claim 7  wherein each of said adjustment arms includes a threaded shaft rotatably engaging said threaded bores for moving said adjustment arms relative to said body portion.  
   
   
       9 . A seat assembly as set forth in  claim 8  wherein said pocket includes openings for receiving said cable therethrough.
