Abstract
A chair has a pair of rodlike supports for contacting the ground, each of which have a first portion under the legs and seat which is curved to a first radius, and a second portion curved to a second radius different from said first radius. A flexible cover is mounted onto cross braces between the rodlike supports with the cover central portion being left hanging.
Claims6
A chair construction, comprising:
- first and second side frames, each including, a continuously curved support element having one concave portion and one convex portion, the convex side being adapted for contacting a ground plane,
- a tubular side member arranged within a support element concave portion having its ends and a central point secured to the said support element, each tubular side member having a first bend at the central point secured to a support element, a second bend above the first bend approximately at shoulder height for a seated chair user, and a third bend substantially behind the knees of a seated chair user;
- a plurality of equilength rodlike braces each having its two ends respectively secured to the first and second side frames forming a unitary framework;
- and
- a flexible sheet of material having opposite end portions connected to two of the braces leaving the central part thereof unsupported providing a seating surface.
