Patent ID: 8590969

Claim:
Dynamic furniture for supporting a seated or reclining user, said furniture comprising: a base; an actuator assembly, in a first orbital connection to said base, having a proximate portion and a distal portion, wherein said base supports said actuator and said first orbital connection restricts said actuator assembly to only a uniform, substantially-circular motion relative to said base, and causes said actuator assembly to move only in one specific circular path relative to said base; a seal platform, in a second orbital connection to said actuator assembly, wherein in said actuator assembly supports said seat platform and said second orbital connection is an eccentric orbital connection that restricts said seal platform, relative to said actuator assembly, to a fixed single path of eccentric motion and causes said seat platform to move only in one specific eccentric path relative to said actuator assembly; a flex joint, motionally linking said seat platform to said back platform, wherein said seat platform is in a direct circular orbital connection with said back platform, said seal platform supports said back platform, and said direct circular orbital connection restricts said seat platform, relative to said back platform, to uniform, substantially circular, single path motion; and a back platform, in a third orbital connection to said actuator assembly, wherein said actuator assembly supports said back platform and said third orbital connection is a circular orbital connection that restricts said back platform, relative to said actuator assembly, to a uniform, substantially circular, fixed single path of motion, and causes said back platform to move only one specific circular path relative to said actuator assembly, wherein said seat platform and said back platform are capable of remaining stationary relative to said actuator assembly while said actuator assembly moves relative to said base, said seat platform and said back platform are capable of moving relative to said actuator assembly while said actuator assembly remains stationary relative to said base, and said seat platform and said back platform are capable of moving relative to said actuator assembly while said actuator assembly moves relative to said base.
