Description

Seats with stable seating

technical field

The utility model relates to a seat with a stabilizing sitting mechanism, which is mainly designated for office chairs to ensure the best position of the spine when sitting.

Background technique

So far, we know that office chairs are mostly equipped with a stable seat that can move up and down. The solution for such seats is based on their fixed connection to the seat back and the kinematic mechanism. Their disadvantage is that they do not provide any solution to the problem of unilateral loading of the spine and pelvis.

The known technical solution is described in the registered Slovak Utility Model No. 5251 named Chair With a Right and Left Flexible Seat Surface, where the right The seat portion and the left seat portion are interconnected by means of connecting means and spring means which are interconnected with a central seat leg. The disadvantage of this technical solution is its undue load on the spine and waist when sitting for longer periods of time.

Another known technical solution is described in the Slovak plant model no. 5153 named Shifting and Fixation Chair, in which at least one leg of the chair is externally and/or internally with at least one bracket Fixed to the ground, this bracket has an opening, while at least one hollow cylinder is fixed to it at the top, a flexible screw is mounted to the fastening element, and the bottom part of the bracket is mounted to the fastening element by a spring with a pad and stop capsule. The disadvantage of this technical solution is that its practicality only specifies inactive people, so it is not suitable in terms of healthy sitting.

Another known technical solution is described in the registered Slovakian facility model No. 2 411 named Kneeling Chairs, this chair structure comprising a shin rest, leg and seat part. It also includes an adjustable fixed kneeling structure in which the first part of the fixing device is placed on the leg or bottom part of the seat, and the backrest, pillow, seat part, or armrest is detachable and consists of several parts. The disadvantage of this technical solution is that the seat can shift the center from the waist and ischia to the knees, and this increases the possibility of overloading, resulting in immobility.

Another known technical solution is described in the registered Slovakian facility model no. 1 350 named Special Chair, in which the legs, backrest, side supports and seat are formed from a monolithic frame, the waste opening ( waste opening) is equipped with external reinforcement straps for fitting the hood over the waste opening and two parallel side straps fit under the seat for insertion of the waste housing under the waste opening. Disadvantages of this technical solution relate to the inability of the special seat to move on the backing plate and unsuitable loads on the spine and lumbar region after sitting for a long time.

Another known technical solution is described in the Slovak installation model registered No. 1 609 named Seat, in which the divided central seat part has a width-adjustable surface extending to the working area of the eccentre and height-adjustable surface, the eccentric is firmly connected to a lever that is rotationally fixed in the seat portion and in the central portion and/or body of the height-adjustable surface, and which has a fixed or fluid or jumping Ground adjustable partial surface. The rear body of the seat has a folding element with a folding body with adjustable parts and a mobile fixator extending to an insert body with a support surface that is adjustably placed in relation to the folding The supporting surfaces have moving bodies with a common axis. Disadvantages of this technical solution relate to the complexity of the technical implementation, the inability to move on the backing board and unsuitable loads on the spine and lumbar region after sitting for a long time.

Another known technical solution is described in the registered Slovakian installation model No. 2 931 named Seat, the seat of which is formed by two surfaces, one of which is placed on top of the other , and between them, in the front part there are fixed front legs, and they are connected in such a way that the lower part of the front part of the seat is inserted into the opening of the upper part, and vertical movement of the legs is impossible because of the The upper part is snapped into the shell or opening in the upper part of the seat, and the two surfaces of the seat are inserted into the openings in the backrest, which is held in place by the rear legs, which are inserted into the prepared upper and lower parts of the seat overlapping the backrest In the mouth. The disadvantages of this technical solution relate to the complexity of the technical implementation, the inability to move on the pad and unsuitable loads on the spine and lower back after sitting for a long time.

Another known technical solution is described in the Czech installation model no. 17 550 named Ergonomic Chair with therapeutic features. The upper surface of the seat is provided with upholstered protrusions designed for a proper position of the legs when sitting, and the backrest is provided with upholstered protrusions designed for a proper position of the upper part of the pelvis. The positioning device enables individual adjustment of the necessary operating positions for correct seating, mainly by adjusting the height of the seat, its inclination, pressure, blocking strength, release, height adjustment of the armrests and headrests. The disadvantages of this technical solution relate to the complexity of the technical implementation and the resulting high manufacturing costs.

Utility model content

The above-mentioned prior art problems are overcome by the seat with stable seating device of the present invention, which is formed by an adjustment assembly detachably mounted to the base from one side and from the The other side mounts securely to the stand with a solid backrest. The stand has a securely attached connection assembly that is rotationally placed from the other side in a housing that is securely mounted to the unstable backing plate or the unstable seat.

It is advantageous to mount the unstable backing plate to the unstable seat.

It is advantageous for the balance stabilizer to be placed loosely between the stand and the unstable seat.

It is also advantageous to have at least one adjustable armrest mounted to the firm backrest.

Furthermore, it is advantageous to form the connection assembly from a ball pin and a dust protection mounted to the housing.
