Seat assembly having a seat cushion rocker mechanism

A seat assembly adapted to be coupled to the floor of an automotive vehicle, said seat assembly comprising:

• a pair of spaced apart risers extending between forward and rearward ends for supporting the seat assembly above the floor of the vehicle;
• a pair of spaced apart track assemblies extending between forward and rearward ends for mounting the seat assembly to the floor of the vehicle;
• a seat cushion coupled to said risers for supporting an occupant in said seat assembly;
• a seat back pivotally coupled to said risers;
• a vertical height adjuster operatively coupled between said risers and said track assemblies for selectively vertically adjusting said seat assembly relative to the floor while simultaneously providing fore and aft adjustment, said vertical height adjuster including a pair of front adjuster links pivotally connecting said forward ends of said risers and said track assemblies, a pair of rear adjuster links pivotally connecting said rearward ends of said risers and said track assemblies, and an actuator operatively coupled to said vertical height adjuster for selectively actuating said vertical height adjuster to provide simultaneous height and fore/aft adjustment of said seat assembly wherein said front and rear adjuster links define an arcuate path of movement relative to the floor of the vehicle;
• and
• wherein each of said front adjuster links define a rocker mechanism for selectively adjusting an angular position of said seat cushion relative to the floor, said rocker mechanism including a sector gear coupled to said riser adjacent said forward end thereof by a pivotal connection and including a mounting pin offset from said pivotal connection to said riser, a rocker link having a first end pivotally coupled to said forward end of said track assembly and a second end pivotally coupled to said mounting pin on said sector gear for supporting and guiding said forward ends of said risers during pivotal movement about said pair of rear adjuster links, and a pawl pivotally coupled to said rocker link for selectively engaging and locking said sector gear to maintain said selectively adjusted angular position of said seat cushion.
