Abstract

The comfortable armchair, seat or reclining chair (2) has a pivotable backrest (11), where the pivot axis (16) of the backrest is positioned relative to the hip joint axis (17) of a person (1). The radius of a support circle (5a) increases around the hip joint axis along a pivot circle of a support element (6) by leaning back of the person. Weight of the lower body of the person alone a hold-down device (13) opposes the lifting of the upper body (3) for holding down the thighs (12) of the person.

Description

at The present invention is a comfortable one Armchair, seat or deck chair, which is used to treat back problems and can be used for relaxation. It's about the spine while sitting to stretch and thus relieve.

There is a system known ( DE 19702171A1 , IPC: A 47 C 7/54), which allows the user to lift himself out of the seat through existing axillary supports, thus extending the spine. However, this solution is not for relaxation, as the user himself has to apply and hold the power to lift himself out of the seat.

In another solution proposal ( DE 10040714A1 , IPC: A 61 H 1/02), the spine is made possible by moving the back up or the seat down. However, this movement of the back part or the seat and thus the extension of the spine is solved by the principle of gravity and amplified by means of a computer-controlled pulling device.

Furthermore, a solution for stretching the spine is known (US Pat. DE 10211145A1 ), which can be used in a rather uncomfortable, lying position while training the muscles. The use of the device for pure relaxation in a sitting position thus does not seem to be possible.

In a further patent application ( DE 102005013362A1 ) is about a relaxation lounger, which is characterized by variable lying positions. However, in this couch no stretching or relief of the spine is possible.

Another known solution ( DE 4413752A1 , IPC: A 61 G 7/015) describes a stretcher that stretches the spine by means of a movable carriage. The stretching takes place via the inclination of the lounger. However, the user is lying with his head down on this couch. This position is certainly not very comfortable in the long run.

It It is therefore the task of a comfortable chair, seat or To create a deckchair for relaxation, the spine can relieve and stretch and also as a comfortable seat serves. This object is achieved with the present invention according to claim 1 solved. Further developments of the invention are described in claims 2 to 6

In this comfortable chair, seat or deckchair ( 2 ) the pivot axis ( 16 ) of the backrest ( 11 ) relative to the hip joint axis ( 17 ) one person ( 1 ) positioned so that the radius of the support circle ( 5a . 5b ) around the hip joint axis ( 17 ) along the pivoting circle of a support element ( 6 ) while reclining the person ( 1 ) by a measure ΔL, shown in 2 , enlarged. This will relieve or stretch the person's spine ( 1 ) achieved. Either the weight of the lower body of the person ( 1 ) alone or in the area of the seat ( 7 ) arranged hold-down ( 13 ) to hold down the thighs ( 12 ) the person ( 1 ) act to raise the upper body ( 3 ) opposite. The person ( 1 ) can be activated by actuating a control element for the swivel mechanism ( 29 ) the angle of inclination of the backrest ( 11 ) latching or steplessly adjusted by clamping elements and the inclination of the backrest ( 11 ) decrease again.

conditioned through the lifestyle of people take the back problems steadily increasing in society. There is therefore a significant need these complaints in the normal environment and under fulfillment counteract today's comfort requirements. The present Invention can meet this need.

In a preferred embodiment of a comfortable chair, seat or deck chair according to the invention ( 2 ) the pivot axis ( 16 ) of the backrest ( 11 ) relative to the hip joint axis ( 17 ) one person ( 1 ) positioned so that the radius of the support circle ( 5a . 5b ) around the hip joint axis ( 17 ) along the pivoting circle of a support element ( 6 ) while reclining the person ( 1 ), so that a relief or extension of the spine of the person ( 1 ) is achieved by either the weight of the lower body of the person ( 1 ) alone or in the area of the seat ( 7 ) arranged hold-down ( 13 ) to hold down the thighs ( 12 ) the person ( 1 ) raising the upper body ( 3 ), whereby the person ( 1 ) by actuating a control element for the pivot mechanism ( 29 ) the angle of inclination of the backrest ( 11 ) latching or steplessly adjusted by clamping elements and the inclination of the backrest ( 11 ) again. In an exemplary embodiment of the invention, the inclination of the backrest ( 11 ) when reclining a person ( 1 ) by a pivoting mechanism ( 8th ) with gear transmission or self-locking worm gear, with or without motor drive, in the connection of backrest ( 11 ) and seat ( 7 ) is installed.

Operation of the swivel mechanism ( 29 ) takes place, for example, by an operating element in the form of an operating lever ( 30 ) with latching lever ( 31 ), located on the right and / or left armrests ( 36 ), thus within reach. The power transmission can via a Bowden cable ( 34 ) and a drive gear ( 33 ) respectively. By tilting the operating lever forwards or backwards ( 30 ) can be a positioning of the backrest ( 11 ) relative to the seat surface ( 7 ), as well as a determination of the position of the backrest ( 11 ) respectively.

There are support elements for the upper body ( 3 ) the person ( 1 ) in the form of bilateral armpit supports ( 10 ) and / or thoracic supports ( 18 ), which surround the thorax and on the backrest ( 11 ) are mounted laterally. These armpits ( 10 ) and / or thoracic supports ( 18 ) are attached to armpit supports ( 21 ) or breast support holders ( 19 ) and by means of both sides of the backrest ( 11 ) for the armpit support holder ( 22 ) as well as locking mechanism for thoracic cap holder ( 20 ) along both sides of the backrest ( 11 ) mounted guide rail for support elements ( 23 ) Positionable and lockable in at least one spatial direction. About these support elements, the spine relieving or stretching forces in the upper body ( 3 ) the person ( 1 ) when the backrest ( 11 ) is tilted backwards.

Above the backrest ( 11 ) is in an exemplary embodiment of the invention, a padded headrest ( 15 ), which as neck / neck support represents an additional support element and contributes to the relaxation of the neck / neck area. Both sides of the seat ( 7 ) are hold-downs ( 13 ) for the thighs ( 12 ) the person ( 1 ), each consisting of a padded holding-down arm ( 27 ), which via a height adjustment of the hold-down ( 24 ) adjustable in height and by means of a locking mechanism for the height adjustment of the hold-down ( 25 ) and via a side of the seat ( 7 ) located guide rail for hold-down ( 23 ) along the seat surface ( 7 ) and by means of associated locking mechanism for the hold-down arm ( 28 ) is fixable. Lowering the thighs ( 12 ) the person ( 1 ) can be either loose or tight.

The backrest ( 11 ) and the seat ( 7 ) are ergonomically shaped, so that when tilting the backrest ( 11 ) the back posture remains largely unchanged and a lateral inclination of the back is prevented. Thus, only a tilt of the upper body ( 3 ) the person ( 1 ) opposite the lower body ( 3a ) around the hip joint axis ( 17 ), which is crucial to the process of extension of the spine.

The equipment of a comfortable chair, seat or deck chair according to the invention ( 2 ) can also be a pivoting lower leg support with footrest ( 37 ), which, for example, via a cable system for transmitting power mechanically with the pivot axis ( 16 ) of the backrest ( 11 ) and thus upon return of the backrest ( 11 ) can expand proportionally to this. The armchair, seat or deckchair ( 2 ) can be mounted on a base ( 35 ) be mounted either fixed or rotatable. By sufficient weight and / or choice of the center of gravity is a stable standing of the chair, seat or deck chair ( 2 ) guaranteed.
