Bicycle seat clamp

Abstract

A bicycle seat clamp arrangement including a bicycle seat having a mounting beam extending lengthwise on an underneath side of the bicycle seat and defining a first surface. A clamp assembly is configured to apply a clamping force to the mounting beam and defines a second surface. The first and second surfaces are configured to interlock in order to inhibit relative fore and aft movement of the bicycle seat and the clamp arrangement. In one arrangement, the surfaces comprise a plurality of interlocking gear teeth. In another arrangement, the surfaces comprise a corresponding plurality of projections and depressions. The first and second surfaces may cooperate to form a wedge configuration to inhibit rocking of the bicycle seat relative to the clamp assembly.

1 . A bicycle seat clamp arrangement, comprising: 
 a mount adapted to extend in a lengthwise direction below a bicycle seat, said mount having a first mounting surface defining at least one protrusion;    a clamp assembly configured to apply a clamping force to said mount to hold said bicycle seat in a desired position relative to said clamp assembly, said clamp assembly defining a second mounting surface defining at least one depression;    wherein said at least one depression and said at least one protrusion are sized and shaped to interlock and thereby inhibit relative fore and aft movement of the bicycle seat and said clamp assembly from said desired position.    
   
   
       2 . The bicycle seat clamp arrangement of  claim 1 , wherein said mount comprises a beam having a web and a transverse section below said web, wherein said at least one protrusion is defined by an outer surface of one of said web and said transverse section.  
   
   
       3 . The bicycle seat clamp arrangement of  claim 1 , wherein said first and second mounting surfaces comprise a wedge configuration to inhibit rocking of said bicycle seat relative to said clamp assembly.  
   
   
       4 . A bicycle seat, comprising: 
 a mount extending below the seat in a lengthwise direction of said seat, said mount having a first non-smooth mounting surface including a plurality of projecting surface features each having a height of at least one-half millimeter.    
   
   
       5 . The bicycle seat of  claim 4 , wherein said plurality of projecting surface features comprises a plurality of gear teeth.  
   
   
       6 . The bicycle seat of  claim 4 , wherein said plurality of projecting surface features comprises a roughened surface finish.  
   
   
       7 . The bicycle seat of  claim 4 , wherein said first non-smooth mounting surface comprises a wedge configuration.  
   
   
       8 . The bicycle seat of  claim 4 , said seat additionally comprising a seat base defining a support surface on an upward-facing side of said seat.
