Puzzle seating

Abstract

A seating assembly with a base, a seat and a back which have interlocking features, and a strap latch removeably securing the back to the base with a portion of the seat sandwiched therebetween. The strap latch comprises a strap affixed to one component, with a latch attached to its free end, and a catch member affixed to another component. The seat may also be configured to appear horizontal but to have a rearward incline when occupied, by affixing the seat webbing to a fixed forward member and a floating rear member, and attaching the floating member to a fixed rear member via straps, wherein the straps and the seat webbing have sufficient elasticity to allow the floating member to be depressed when a downward force is applied to the seat.

1 . A chair seat comprising:
 a fixed frame, including front and back members;   a floating frame member;   at least one first securing element, secured to and affixing said floating frame member to said back member of said fixed frame;   seat webbing, attached along one edge to said front member of said fixed frame and attached along the opposing edge to said floating rear frame member; and   wherein said seat webbing and said first securing element have sufficient elasticity to allow said floating rear frame member to be displaced in the downward direction when a downward force is applied to the seat webbing, such that the chair seat appears flat when not occupied, but has a rearward and downward incline when occupied.   
     
     
         2 . The chair seat of  claim 1 , in which there are two of said securing elements, spaced apart from one another, and secured to and affixing said floating frame member to said back member of said fixed frame. 
     
     
         3 . The chair seat of  claim 2 , in which the securing elements are straps. 
     
     
         4 . A seating assembly, comprising:
 first and second seating components;   said first seating component comprising a back and said second seating component comprising a base, said first and said second seating components are releasably secured together without the need for tools;   an interlocking system for releasably securing together said first and said second seating components, said interlocking system comprising:
 at least one first interlocking element affixed or releasably securable to said first seating component; 
 at least one second interlocking element affixed or releasably securable to said second seating component; 
 said first interlocking element being releasably securable with said second interlocking element, for securing said first seating component to said second seating component; 
   at least one third component, wherein at least two of said first, second and third components interlock with each other through said interlocking system when said components are placed into position so as to form said seating assembly;   said seating assembly further comprising a seat, said seat comprising:
 a fixed frame, including front and back members; 
 a floating frame member; 
 at least one third interlocking element, secured to and affixing said floating frame member to said back member of said fixed frame; 
 seat webbing, attached along one edge to said front member of said fixed frame and attached along the opposing edge to said floating frame member; and 
 wherein said seat webbing and said at least one third interlocking element have sufficient stretch to allow said floating frame member to be displaced in the downward direction when a downward force is applied to the seat webbing, such that the seat of the seating assembly appears flat when not occupied, but has a rearward and downward incline when occupied. 
   
     
     
         5 . The seating assembly of  claim 4  wherein said back comprises:
 two side members joining a back support; 
 a connecting brace, which extends between said side members and is fixedly attached at each end to one of the side members; and 
 one end of said first interlocking element being attached to said connecting brace and said second interlocking element being attached to said base. 
 
     
     
         6 . The seating assembly of  claim 4 , wherein said base accommodates an arm; said arm being releasably fastened to said base using a fourth interlocking element. 
     
     
         7 . The seating assembly of  claim 6 , wherein said arm and said seat include said interlocking features, whereby said arm is releasably secured to said base by said seat as well as said fourth interlocking element. 
     
     
         8 . The seating assembly of  claim 7 , comprising a second seating assembly releasably ganged to the first seating assembly by a fifth interlocking element, wherein the fifth interlocking element comprises one end affixed to one of said first and second seating assemblies and another end affixed to the other of said seating assemblies, wherein said fifth interlocking element is used to secure the first seating assembly to the second seating assembly. 
     
     
         9 . The seating assembly of  claim 7 , wherein said arm and said seat interlocking features include at least one interlocking projection on said arm which projects laterally into a portion of said base which accommodates said seat; and said seat includes a side rail which is seated over said arm projection to lock it in place when said seat is properly located on said base. 
     
     
         10 . The seating assembly of  claim 9 , wherein said base includes a front base frame member having spaced slots therein; said seat having a front seat frame member with rearwardly extending projections located to engage said slots when said seat is properly located on said base. 
     
     
         11 . The seating assembly of  claim 10 , wherein said back comprises:
 two side members joining a back support;   a connecting brace, which extends between said side members and is fixedly attached at each end to one of the side members; and   one end of said fourth interlocking element being attached to said connecting brace and another end of said fourth interlocking element being attached to said base.
