Patent ID: 8500203

Claim:
Dynamic furniture for supporting a seated or reclining user, said furniture comprising: a base; an actuator assembly, in excentric orbital connection to said base, having a proximate portion and a distal portion, wherein said base supports said actuator assembly and said excentric orbital connection restricts said actuator assembly to a fixed single path of excentric motion relative to said base; a seat platform, in orbital connection to said actuator assembly, wherein said actuator assembly supports said seat platform and said orbital connection enables an orbital single path of travel that is fixed for said seat platform relative to said actuator assembly; a back platform, in orbital connection to said actuator assembly, wherein said actuator assembly supports said back platform and said orbital connection enables an orbital single path of travel for said back platform that is fixed relative to said actuator assembly; and a flex joint, motionally linking said seat platform to said back platform; and 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; and wherein 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 wherein 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.
