Vehicle seat with rear stow pivot assembly

Abstract

A vehicle seat pivot assembly is provided including a support assembly, an arm, and a first load cam. The arm is supported on the support assembly for pivotal displacement between a first position and a second position. The first load cam is pivotally supported on the support assembly to selectively engage a first sector plate. The first load cam engages a first portion of the first sector plate to lock the arm in the first position. The first load cam engages a second portion of the first sector plate to lock the arm in the second position.

1 . A vehicle seat pivot assembly, comprising: 
 a support assembly;    an arm supported on said support assembly for pivotal displacement between a first position and a second position; and    a first load cam pivotally supported on said support assembly to selectively engage a first portion of a first sector plate to lock said arm in said first position and a second portion of said first sector plate to lock said arm in said second position.    
   
   
       2 . The seat pivot assembly of  claim 1  wherein said first sector plate includes a first notch for receiving a portion of said first load cam when said arm is locked in said first position and a second notch for receiving a portion of said first load cam when said arm is locked in said second position.  
   
   
       3 . The seat pivot assembly of  claim 1  wherein said first sector plate is fixed for rotation with said pivotal displacement of said arm.  
   
   
       4 . The seat pivot assembly of  claim 1  further comprising a biasing member biasing said first load cam into engagement with said first sector plate.  
   
   
       5 . The seat pivot assembly of  claim 1  further comprising a second load cam pivotally supported on said support assembly to selectively engage a second sector plate and lock said arm in said first position.  
   
   
       6 . The seat pivot assembly of  claim 5  wherein said second sector plate includes a notch for receiving a portion of said second load cam when said arm is locked in said first position.  
   
   
       7 . The seat pivot assembly of  claim 5  wherein said second sector plate is fixed for rotation with said pivotal displacement of said arm.  
   
   
       8 . The seat pivot assembly of  claim 1  further comprising a stop pin disposed on said arm for engaging said support assembly and preventing said arm from pivoting beyond said first and second positions.  
   
   
       9 . A vehicle seat pivot assembly, comprising: 
 a support assembly;    an arm supported on said support assembly for pivotal displacement between a first position and a second position;    a stop pin disposed on said arm and engaging said support assembly when said arm is in said first position to apply a torque thereto in a first direction;    a first sector plate supported for rotation with said pivoted displacement of said arm; and    a first load cam pivotally supported on said support assembly and operable to lock said arm in said first position through engagement with said first sector plate and apply a torque to said arm in a second direction that is opposite said first direction.    
   
   
       10 . The seat pivot assembly of  claim 9  wherein said first sector plate includes a first notch for receiving a portion of said first load cam when said arm is in said first position and a second notch for receiving a portion of said first load cam when said arm is in said second position.  
   
   
       11 . The seat pivot assembly of  claim 9  wherein said first sector plate is fixed to said arm.  
   
   
       12 . The seat pivot assembly of  claim 9  further comprising a biasing member biasing said first load cam into engagement with said first sector plate.  
   
   
       13 . The seat pivot assembly of  claim 9  further comprising a second load cam pivotally supported on said support assembly to engage a second sector plate and lock said arm in said first position.  
   
   
       14 . The seat pivot assembly of  claim 13  wherein said second sector plate includes a notch for receiving a portion of said second load cam.  
   
   
       15 . A vehicle seat assembly, comprising: 
 a seating member;    an arm attached to said seating member and supported on a support assembly for pivotal displacement between a first position wherein said seating member is in a seating position, and a second position wherein said seating member is in a stowed position;    a first load cam pivotally supported on said support assembly for selectively engaging a first sector plate to lock said seating member in said seating and stowed positions; and    a second load cam pivotally supported on said support assembly for selectively engaging a second sector plate to lock said seating member in said seating position.    
   
   
       16 . The seat assembly of  claim 15  further comprising a stop pin disposed on said arm and engaging said support assembly when said seating member is in said seating position to apply a torque thereto in a first direction.  
   
   
       17 . The seat assembly of  claim 16  wherein said first load cam applies a torque to said first sector plate in a second direction that is opposite said first direction when said seating member is in said seating position.  
   
   
       18 . The seat assembly of  claim 15  wherein said first sector plate includes a first notch for receiving a portion of said first load cam when said seating member is in said seating position and a second notch for receiving a portion of said first load cam when said seating member is in said stowed position.  
   
   
       19 . The seat assembly of  claim 15  wherein said second sector plate includes a notch for receiving a portion of said second load cam when said seating member is in said seating position.  
   
   
       20 . The seat assembly of  claim 15  wherein said first and second sector plates are fixed for rotation with said pivotal displacement of said arm.
