A stackable chair includes a seat assembly and flexible back support having a seat spring system attached therebetween. The seat assembly includes seat sides having spaced apart rear portions. The back support includes lower ends curved forwardly and disposed in registry with and separated by right and left gaps from respective seat side rear portions. Right and left spring members are disposed inwardly adjacent to bridge each gap. Each spring member includes forward ends connected to respective right and left front support members extended inbound from respective seat sides, and includes rear ends connected to opposed ends of a frame rear cross-member. The spring members allow limited reclining movement of the back frame. A limit to excessive forward movement of the back support is provided by pairs of fixation plates positioned in aligned and abutting relationship on upper surfaces of each respective forward and rear ends of each spring member.

Flexible back mechanism for stackable chairs

A chair frame () for a stackable chair. The chair frame () includes a seat support portion () for support the seat portion () of a chair, and includes a pair of leg assemblies () oppositely disposed on either side of the seat support portion (). Each leg assembly () includes a front leg () and a rear leg (), and an upper support member (). Each upper support member () has an upper surface (), at least a portion of which defines a curvilinear surface portion. Each leg assembly () also includes a stacking bar () extending between the front leg () and the rear leg (), the stacking bar () being disposed below, and being selectively space from, the upper support member (). The stacking bar () of each leg assembly () has a lower surface (), at least a portion of which defines a curvilinear surface portion configured to closely engage at least a portion of the curvilinear surface portion of the upper surface () of the upper support member () of another chair frame () to facilitate the stacking of a plurality of chairs utilizing the chair frame ().

A molded foam spring seat includes a seat cushion having a bottom surface supported by a support frame having an opening therein. A drop-in frame is insertable within the opening, with the drop-in frame including a pair of opposed walls having fastening means thereon. A plurality of compression springs are each detachably extended between the fastening means on the drop-in frame. Each compression spring is in partial compression until compressed downward by a user seated on the seat cushion. Each compression spring resiliently rebounds to partial compression when the seat cushion is not compressed. The seat cushion includes sides tapered inwardly toward a seat cushion upper surface to reduce bulging of each side outwards with repetitive use of the seat cushion, and to minimize wear on the seat cushion sides when other seat cushions and support frames are positioned adjacent, or are stacked on the seat cushion.

Molded foam spring seat

A chair including a seat assembly having an improved seat spring system to provide a flexible spring backrest frame. A pair of ends of spaced apart backrest frame members are arranged in registry with respective ends of seat support frame members, with each end positioned in spaced apart alignment across a gap from the respective end of each frame member. An elongated shaped flexible spring element spans each gap, with each spring element having opposed ends being extended a distance along each frame member from the gap. Each opposed end is restrained by a first and a second elongated U-shaped holder receptor paired and separately attachable to each opposed end of the spring element. Each holder receptor includes an opening end being faced towards and in alignment with the second holder opening end. The spring element is positioned between each opening end in side-by-side orientation beside the frame members, providing controlled angular range of motion of the backrest frame when moved by a chair occupant. The spring element is constrained from excessive flex by each holder receptor having projection ends that contact each other proximate a mid-point of the spring element to limit range of motion. The seat spring system includes few parts of low-cost materials that are accessible for adjustments by being exterior to the chair frame while controlling the range of motion of the chair backrest.
