Dynamic furniture

Abstract

Dynamic furniture having platforms in dynamic attachment to an actuator assembly that in turn is in dynamic attachment to a base. Use of motional platforms supported by a motional actuator assembly permits an article of the furniture to conform to the many and varied body positions a user wants, and allows a user to more easily change body positions while remaining within the furniture, and in medical scenarios may obviate most needs to transfer a patient from one article of furniture to another.

What is claimed is: 
     
       1. Dynamic furniture for supporting a seated or reclining user, said furniture comprising:
 a base; 
 an actuator assembly consisting of two elongate, parallel members, each member having a proximate portion and a distal portion, wherein said actuator is in excentric, restrained, and substantially centralized orbital connection to said base between said proximate portions and distal portions of said members; 
 a seat platform, in orbital, restrained, and single connection to said proximate portion of said actuator assembly and disposed at least partially within said parallel members; and 
 a back platform, in orbital, restrained, and single connection to said proximate distal portion of said actuator assembly and disposed at least partially within said parallel members, and 
 wherein said seat platform is capable of rotation about said seat platform orbital connection without displacing said back platform, 
 wherein said back platform is capable of rotation about said back platform orbital connection without displacing said seat platform, 
 wherein vertical displacement of said seat platform proximate to said seat platform orbital connection displaces said actuator to further displace said back platform, and 
 wherein vertical displacement of said back platform proximate to said back platform orbital connection displaces said actuator to further displace said seat platform. 
 
     
     
       2. The dynamic furniture of  claim 1  whereby said seat platform and said back platform comprise orbital connections dimensioned to allow said seat platform and said back platform to selectively pass through a substantially planar orientation to achieve positions including an upright position, a reclining position, and a flexing position. 
     
     
       3. The dynamic furniture of  claim 2  wherein said seat platform is in excentric orbital connection to said proximate portion of said actuator assembly. 
     
     
       4. The dynamic furniture of  claim 3  wherein said back platform is in excentric orbital connection to said distal portion of said actuator assembly. 
     
     
       5. The dynamic furniture of  claim 3  wherein said back platform is in circular orbital connection to said distal portion of said actuator assembly. 
     
     
       6. The dynamic furniture of  claim 2  wherein said seat platform is in circular orbital connection to said proximate portion of said actuator assembly. 
     
     
       7. The dynamic furniture of  claim 6  wherein said back platform is in circular orbital connection to said distal portion of said actuator assembly. 
     
     
       8. The dynamic furniture of  claim 6  wherein said back platform is in excentric orbital connection to said distal portion of said actuator assembly.
