Seat suspension shock absorber

Abstract

The present invention concerns a seat suspension that includes a first section and a second section which are moveably connected. A deformable isolator is located between the sections. The isolator is held in place by a retaining means such a ring, post and in other ways. The isolator is comprised of a plurality of gaps separating solid sections which cooperate to resist the movement of at least one of the sections. This may be accomplished by resisting the movement of the section as it is urged against the isolator.

What is claimed is:  
     
         1 . A seat suspension comprising: 
 a first section and a second section opposingly located from said first section;    said first and second sections moveably connected to permit said first section to move relative to said second section;    a deformable isolator in communication with said sections and comprising a plurality of solid sections separated by gaps, said isolator resists movement of said first section when a portion of said first section is urged against said isolator.    
     
     
         2 . The device of  claim 1  wherein said gaps are larger in size near the center of said isolator.  
     
     
         3 . The device of  claim 1  wherein said isolator creates a resistance force which exponentially increases.  
     
     
         4 . The device of  claim 1  wherein said suspension resists fore and aft movement.  
     
     
         5 . The device of  claim 1  where said suspension resists vertical movement.  
     
     
         6 . A seat suspension comprising: 
 a first section and an opposingly located second section, said first section moveable relative to said second section;    a deformable isolator in communication with said first and second sections;    an actuator depending from said first section and in communication with said isolator;    said isolator resists movement of said first section and returns said first section to an operating position.    
     
     
         7 . The device of  claim 6  wherein said isolator contains a plurality of gaps.  
     
     
         8 . The device of  claim 6  wherein said isolator includes at least one aperture which receives said actuator.  
     
     
         9 . The device of  claim 6  wherein an outer edge of said isolator is engaged by said actuator.  
     
     
         10 . The device of  claim 6  wherein said isolator is engaged by a portion of said second section.  
     
     
         11 . The device of  claim 6  wherein said isolator is engaged by an enclosure located on said second section.  
     
     
         12 . The device of  claim 6  wherein said suspension resists fore and aft movement.  
     
     
         13 . The device of  claim 6  wherein said suspension resists vertical movement.  
     
     
         14 . The device of  claim 6  wherein said isolator creates a resistance force which exponentially increases.  
     
     
         15 . The device of  claim 7  wherein said gaps are larger in size near the center of said isolator.  
     
     
         16 . A seat suspension comprising: 
 first section and second sections moveably connected;    a deformable isolator located between said sections and held in place by a retaining means; and    said isolator comprising a plurality of gaps separating solid sections which cooperate to resist movement of at least one of said first and second sections by resisting said movement of said at least one of said first or second sections when a portion of said one of said first or second sections is urged against said isolator.    
     
     
         17 . The device of  claim 16  wherein said sections are slidingly connected by guides.  
     
     
         18 . The device of  claim 16  wherein said suspension resists fore and aft movement.  
     
     
         19 . The device of  claim 16  where said suspension resists vertical movement.  
     
     
         20 . The device of  claim 16  wherein said gaps are larger in size near the center of said isolator.  
     
     
         21 . The device of  claim 16  wherein said isolator creates a resistance force which exponentially increases.  
     
     
         22 . The device of  claim 16  wherein said retaining means is comprised of a plurality of pins which extend into said isolator.  
     
     
         23 . The device of  claim 16  wherein said retaining means is comprised of an enclosure which engages an outer edge of said isolator and at least one pin which extends into said isolator.  
     
     
         24 . The device of  claim 23  wherein said enclosure surrounds the outer edge of said isolator.  
     
     
         25 . The device of  claim 23  wherein said enclosure is comprised of a plurality of segments.
