Abstract
Abstract A stacking chair comprising a sheetform seat and back member in one or more pieces, a base member comprising two leg members in the form of a tube or rod which are substantial mirror images of each other and each of which has an upper generally horizontal and rearward reach, a forward generally vertical reach, and a forward angularly outwardly extending reach terminating in a generally horizontal rearward reach constituting a floor-engaging portion of the leg member, a central recess being provided at the forward edge of the seat portion of said chair having dimensions suitable to receive the generally vertical reach of the base member of an identical stacking chair, the stacking height of the leg members and thickness of the seat portion of the sheetform seat and back member enabling close vertical nesting of a plurality of identical chairs upon stacking, at least at some point on said reaches.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
190 words
A stacking chair comprising a sheetform seat And back member and a base member comprising two leg members in the form of a tube or rod, said leg members being substantial mirror images of each other and each having an upper generally horizontal and rearward reach, a forward generally vertical reach, and a forward angularly outwardly extending reach terminating in a generally rearward reach constituting the floor-engaging portion of said leg member, said mirror image leg members being secured together at their upper generally horizontal reaches and including a laterally extending seat support member extending therefrom, said seat support member being secured to a seat portion of said sheetform seat and back member, a central recess being provided at the forward edge of the seat portion of said chair having dimensions suitable to receive therein the generally vertical reach of the base member of an identical stacking chair, the generally horizontal floor-engaging reaches of said leg members and said angularly outwardly extending reaches of said leg members being adapted to engage and support identical reaches of said identical stacking chair upon stacking, at least at some point on said reaches.
Claim 2
Dependent Claim
190 words
A stacking chair comprising a sheetform seat And back member and a base member comprising two leg members in the form of a tube or rod, said leg members being substantial mirror images of each other and each having an upper generally horizontal and rearward reach, a forward generally vertical reach, and a forward angularly outwardly extending reach terminating in a generally rearward reach constituting the floor-engaging portion of said leg member, said mirror image leg members being secured together at their upper generally horizontal reaches and including a laterally extending seat support member extending therefrom, said seat support member being secured to a seat portion of said sheetform seat and back member, a central recess being provided at the forward edge of the seat portion of said chair having dimensions suitable to receive therein the generally vertical reach of the base member of an identical stacking chair, the generally horizontal floor-engaging reaches of said leg members and said angularly outwardly extending reaches of said leg members being adapted to engage and support identical reaches of said identical stacking chair upon stacking, at least at some point on said reaches.
Claim 3
Dependent Claim
40 words
The combination of claim 1, wherein the thickness of the seat member includes bumper means for compensation for difference between the stacking height of said leg members and the thickness of the seat portion of said sheetform member per se.
Claim 4
Dependent Claim
20 words
The combination of claim 1, wherein said leg members are also secured to each other at their generally vertical reaches.
Claim 5
Dependent Claim
35 words
The combination of claim 1, wherein said sheetform seat and back member comprises two identical members positioned at opposite sides of the upper horizontal reach of said base member and secured to seat support members.
Claim 6
Dependent Claim
21 words
The combination of claim 4, wherein said sheetform seat and back members are also secured together at the back portions thereof.
Claim 7
Dependent Claim
35 words
The combination of claim 4, wherein said seat and back members are slightly pitched inwardly toward the upper horizontal and rearward reach of said base member and toward the space between their respective back portions.
Claim 8
Dependent Claim
36 words
The combination of claim 4, wherein said seat and back members are secured to said base member by seat support means extending into apertures provided in the seat portions thereof for receiving said seat support members.
