Problems solved by technology

They do not solve the origin of the diseases, resulting above all from a longlasting sitting on seats of e.g. chairs, armchairs etc.
Their limitation is a complicated structure, which also affects their overall appearance.
A considerable disadvantage of known solutions is in that the sitting area is designed as a rigid structure with no or with only an insufficient adaptability of its form to the forms and dimensions of the user.
They bring no really complete solution of the essential problem, arising from a longlasting sitting because of the said lack of adaptability to the anatomic forms and dimensions

example 1

[0013] The example shows the seat area 1 as fastened on the carrying structure of an armchair 5. The basic dimensions of the seat area are:

width of the seat area w=450 mm

spacing of inner tangents d=110 mm

depth of the seat area h=450 mm

central angle α=90°

angle of the intersection line β=70°.

[0014] The carrying structure 5 consists of a level carrying tube 5.1 on both extremities of which the armchair foots 5.2 are fastened. At the middle of the carrying tube 5.1 a carrying bracket 5.3 is fastened. The blank 2 is fitted in its central part 3 with a sleeve 4 on which a fastening element 4.1 is situated.

[0015] An elastic deformation of the blank 2 is obtained in fixing it by the ends of its normals n1, n2 to the carrying tube 5.1 and in fixing its central part 3 by means of the sleeve 4 with its fastening element 4.1 to the bracket 5.3. The fastening element 4.1 is suspended on the bracket 5.3 on a sliding hinge, giving it a freedom of rocking movements. The implementation sh...

example 2

[0016] The example shows an armchair with a carrying structure 5 and a seat area 1 of identical dimensions and forms of Example 1. The seat area 1 is made of a blank 2 composed of two sections 2.3, 2.4, where a joint of the two sections 2.3, 2.4 is performed by means of a mechanism 6, permitting to change the spacing of the extremities of said sections and consequently enabling a widening or narrowing of the seat area 1. The mechanism 6 is fastened with freedom of shifting on the bracket 5.3 of the carrying structure 5, and it replaces the sleeve 4. A simple implementation of the mechanism 6 is in that two openings 2.31, 2.32 and 2.41, 2.42 respectively with identical spacing are shaped on compatibly modified extremities of sections 2.3, 2.4. An overlapping sheet 6.1 is fastened to the bracket 5.3 by means of a nut 6.3 and a screw 6.2, the screw 6.2 being slung through suitably chosen openings 2.31 or 2.32 and 2.41 or 2.42 respectively.

Abstract

A seat area has a form shaped by an elastic deformation of at least one flat blank (2) delimited by two concentric arches with a center angle from 10° to 170°, while their ends continue by tangents terminated by normal lines. An elastic deformation of the blank (2) into the shape of a seat area (1) is obtained by fastening the flat blank (2) in at least three points of a carrying structure (5). The seat area can be made as a molded piece, or of an elastic single-layer stuff, or of a sandwich-type material. The seat area has a maximum adaptability to the forms and dimensions of the user.

Description

TECHNICAL FIELD [0001] The seat area being an object of the invention belongs to the technical field of sitting furniture, intended for schools, offices, household, catering institutions, transport vehicles and special working places requiring a longlasting sitting. BACKGROUND ART [0002] Known are solutions of chair seats with a compact area whose parts in the anal and genitals location are free and / or have a possibility of getting free by means of an inserted section having various thickness. In an alternative solution the inserted area is continually displaceable. Such solution is known from the utility model DE 9416674.9. It represents a solution of a seat area having a recess in the location of the anal outlet, genitals and tailbone, the femoral parts being stabilized by rotary areas serving for constriction of the movements of a physically disabled person. [0003] The patent specification DE 441479 shows a solution of a seat area composed of two tilting planes. The solution acco...
