Definitions
- 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.
- the solution according to US 4643 481 Patent is a seat area consisting of two channel-like sections for location of the thighs with the aim of their stabilization, while in the area of the anal outlet the seat has a mushroom-like throughgoing opening.
- the seat area can be tilted.
- the solutions mentioned above are suitable only for physically disabled persons and their aim is constricting the movements of the sitting part of a sitting person. 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.
- the seat area has a form shaped by the elastic deformation of at least one at least single-part flat blank.
- the flat blank is delimited by two concentric circular arches with a center angle of 10° to 170 °, continued as their tangents at the arch ends and ending by normal lines at the ends of the tangents.
- the deformation of the flat blank is obtained by its fastening in at least three points of the carrying structure. Fastening of the blank ends, i.e. of the normal lines, is made so that the normal lines are supported on conical areas with a top at the center of a connecting line of the inner ends of the normal lines and with a top angle of 0 ° to 10 °.
- the third fastening point is in the central part, i.e. at the place of the arch tops. After the fastening the intersection line of the seat area forms with its vertical symmetry plane and the horizontal plane an angle of 15 ° to 90 °.
- the central part at least one sleeve is situated, fitted with an element, which is fastened preferably with freedom of shifting and rocking on the carrying structure, so that the sleeve can make rocking motions in all directions.
- the width of the seat area can be made of two sections of the flat blank. The ends of said sections are adapted at the place of their contact as compatible with each other and are fastened in an assembly, allowing to change the distance between the ends of said sections.
- the seat area can be manufactured as a molded piece or of an elastic single-layer stuff or of sandwich-type materials or their combination. In all modifications the blank or section rims can have a form modified shape.
- Fig. 1 shows schematically the flat blank
- Fig. 2 shows schematically the blank in its deformed condition
- Fig. 3 is a side view of an armchair with a seat area
- Fig. 4 is a plan view of an armchair with the seat area
- Fig. 5 is the mechanism in its basic position
- Fig. 6 shows the mechanism in a first increased spacing of the extremities of the seat area sections.
- the carrying structure 5 consists of a level carrying tube 5_ ⁇ on both extremities of which the armchair foots 5 are fastened. At the
- a carrying bracket 5L3 85 middle of the carrying tube 5J.
- a carrying bracket 5L3 is fastened.
- the blank 2 is fitted in its central part 3 with a sleeve 4 on which a fastening element ⁇ _ is situated.
- An elastic deformation of the blank 2 is obtained in fixing it by the ends of its normals n ⁇ n 2 to the carrying tube 5.1 and in fixing its central
- the fastening element 4 is suspended on the bracket 5 ⁇ 3 on a sliding hinge, giving it a freedom of rocking movements.
- the seat area 1 is made of a single-layer elastic stuff.
- Example 2 shows an armchair with a carrying structure 5 and a seat area of identical dimensions and forms of Example 1.
- the seat area 1 is made of a blank 2 composed of two sections 23, 24, where a joint of the two sections 3, 24 is performed by means of a mechanism
- 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
