48 The glider chair of claim 47 wherein said loading means comprises a camber angle provided between said pair of front glide links and said base glide assembly and between said pair of rear glide links and said base glide assembly, whereby a vertical load applied to said glide bracket induces lateral loading of said glider mechanism
49 The glider chair of claim 47 wherein said loading means compπses
said base glide assembly having a base frame, a pair of front glide upnghts cantilevered upwardly from said base frame, and a pair of rear glide upπghts cantilevered upwardly from said base frame, and
said pair of front glide links spaced laterally outwardly from said pair of front upπghts, and said pair of rear glide links spaced laterally outwardly from said pair of rear upnghts,
whereby a vertical load applied to said glide bracket induces lateral loading of said glider mechanism
50 The glider chair of claim 47 wherein said loading means comprises said glide bracket having a first vertical flange portion pivotally connected to said pair of front and rear glide links and a second vertical flange portion secured to said chair frame, said second vertical flange portion being offset laterally outwardly from said first vertical flange portion by a horizontal flange portion
51 The glider chair of claim 47 further comprising
said seat deck including a pair of side frame members spaced laterally apart by a front cross member and a rear cross member to define a chair width,
said glide bracket having a first vertical flange portion pivotally connected to said pair of front and rear glide links and a second vertical flange portion secured to said chair frame a glider mechanism width defined by the distance between said second vertical flange portions of said pair of four bar linkages, and
said chair width being greater than said glider mechanism width such that a lateral load is applied to said glider mechanism when said glider mechanism is secured to said seat deck
52 The glider chair of claim 51 wherein said glide bracket further compπses a nb formed in said glide bracket and extending vertically from said first vertical flange portion through said horizontal flange portion to said second vertical flange portion
53 The glider chair of claim 34 further comprising a swivel plate interdisposed between said base and said base glide assembly for permitting rotational movement of said base glide assembly with respect to said base
54 A glider chair comprising
a base glide assembly having a base supported on a floor surface,
a glider mechanism including a left four bar linkage and a right four bar linkage, each of said left and right four bar linkage including a glide bracket having a first vertical flange portion and a second vertical flange portion offset laterally outwardly from said first vertical flange portion by a hoπzontal flange portion, a front glide link having a first end pivotally connected at a front upper pivot to said base glide assembly and a second end pivotally connected at a front Iower pivot to said first vertical flange portion of said glide bracket, and a rear glide link having a first end pivotally connected at a rear upper pivot to said base glide assembly and a second end pivotally connected at a rear lower pivot to said first vertical flange portion of said glide bracket; and
a chair frame having a pair of side walls interconnected by a seat deck, said chair frame secured to said second vertical flange portion of said glide bracket for permitting gliding movement of said chair frame with respect to said base glide assembly.
55. The glider chair of claim 47 further comprising said seat deck having a pair of side frame members spaced laterally apart by a front cross member and a rear cross member to define a chair width, said chair width being greater than a glider mechanism width defined by a distance between said second vertical flange portions of said left and right four bar linkages, such that a lateral load is applied to said glider mechanism when said glider mechanism is secured to said seat deck.
56. The glider chair of claim 54 wherein said glide bracket further compπses a rib formed in said glide bracket and extending vertically from said first vertical flange portion through said horizontal flange portion to said second vertical flange portion.
57. The glider chair of claim 54 further comprising a swivel plate interdisposed between said base and said base glide assembly for permitting rotational movement of said base glide assembly with respect to said base.
