Abstract
Abstract A chair comprises a seat; a support for the seat; and, a plurality of biasing members mounted between the support and the seat, the biasing members, in combination, have a compressive strength sufficiently high to essentially resist static movement of a person while seated in the chair and sufficiently low to cushion dynamic loads applied to the seat when a person sits down quickly in the chair. Alternately the chair comprises a plurality of connecting members extending between the seat and the support, each connecting member having at least one first detent member to lockingly connecting the seat to the support.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
111 words
A chair comprising: (a) a seat having a lower surface; (b) a support for the seat; and, (c) a plurality of connecting members extending between the seat and the support, each connecting member having at least one first detent member to lockingly connect the seat to the support; and, (d) a plurality of second detent members having an engagement surface to abut a surface of the first detent members, the first detent member comprising spaced apart end members which are resiliently biased to a spaced apart position and which are compressible towards each other to permit slidable insertion into the second detent member and slidable removal from the second detent member.
Claim 2
Dependent Claim
111 words
A chair comprising: (a) a seat having a lower surface; (b) a support for the seat; and, (c) a plurality of connecting members extending between the seat and the support, each connecting member having at least one first detent member to lockingly connect the seat to the support; and, (d) a plurality of second detent members having an engagement surface to abut a surface of the first detent members, the first detent member comprising spaced apart end members which are resiliently biased to a spaced apart position and which are compressible towards each other to permit slidable insertion into the second detent member and slidable removal from the second detent member.
