Abstract
Abstract A sitting device for freely chosen or fixedly attached mounting on a floor and on a subframe, or for attachment to vertical surfaces, said device comprising an array of supporting faces consisting of at least two such faces, neighboring supporting faces having different positions. One of the two neighboring supporting faces may serve to support the posterior of the occupant and the other to support the calf. Alternatively one serves to support the back and the other to support the posterior. The supporting faces comprise a forwardly inclined seat cushion and a calf cushion forming a mutual angle of at least 90°. The supporting faces may be arranged at a distance from each other and with free space between these. They may be mechanically linked with each other. A set of two posterior supports, a common calf support and a common table is provided.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
194 words
A sitting device for use by at least first and second occupants sitting one behind the other, and facing forward comprising: at least two identical integral and generally inverted L-shaped units supported in spaced-apart positions fixed relative to each other and disposed one behind the other with free space between them, each unit including first and second supporting faces corresponding to an upper generally horizontal leg of the inverted L-shape and the generally vertical leg thereof, respectively; a posterior support for the first occupant being formed by the first supporting face of one unit and the second supporting face of the same unit forming a shin support for the second occupant seated on the other unit behind the first occupant, the first supporting face of the other unit forming a posterior support for the second occupant; and the first supporting face of each unit being in the form of a substantially unobstructed inclined surface extending across the unit, whereby the occupants may adjust their position on the first supporting faces so as to engage the second supporting faces with their shins regardless of variations in the lengths of the upper legs of different occupants.
Claim 2
Dependent Claim
