Definitions

• the present invention relates to a seat, a seat cover, a seat frame or a corresponding device.
• the invention has for its object to provide a seat, a seat cover, a seat frame or a corresponding device which, with simple design and manageable means, largely relieves the back or spine of the user of the seat, the seat cover , the seat frame or the corresponding device.
• this object is achieved in the case of a seat, a seat cover, a seat frame or a corresponding device in that he or she is provided with armpit supports which extend approximately perpendicular to the backrest plane and protrude from it.
• the invention thus proposes the arrangement of armpit supports on the seat, on the seat cover, on the seat frame or on the corresponding device, these armpit supports extending approximately vertically from the backrest plane to the front.
• the armpit supports are each arranged so that the seat user can put his arms around or on the supports, which support the armpit area of the seat user. This allows the upper body area of the seat user to be supported on the armpits, which relieves his skeleton (spine, pelvis). If the armpits are arranged high enough, the spine is stretched, ie the body of the seat user is "lifted", so to speak.
• the seat user can use the armpit to based on taking for any length of time.
• seat or “seat frame” used here is intended to encompass all seats or corresponding devices serving human use, such as, for example, seating furniture, such as office chairs, car seats, truck seats, bus seats, railroad seats, aircraft seats, tram seats, U- railway seats, living room armchairs, hairdressing chairs, dentist chairs,
• "Seat frame” also means auxiliary devices which can be fitted to existing seats and which have corresponding armpit supports. Such racks can be mounted as desired, for example from the rear.
• the term “seat cover” means a device consisting of a backrest alone or backrest and seat element, which can be placed on existing seats and, if necessary, can be fixed thereon.
• the armrests are preferably adjustable, in a particularly preferred manner both upwards and downwards and in the lateral direction.
• the adjustability can be done manually, but is preferably automatic, ie via a mechanical, pneumatic, hydraulic or electrical drive.
• a suitable control part for example one or more control buttons, can be provided on the seat or the seat cover, the actuation of which causes the armpit supports to move.
• the axillary supports can be adjusted without contacting the axillary region of a seat user.
• the seat user preferably first assumes his corresponding sitting position and puts his arms over the armpits.
• the supports are then adjusted to the position of his armpits, preferably in both the lateral and vertical directions.
• the body of the seat user can then be "raised”, i.e. be raised until his buttocks only lightly touch the seat. This results in the desired relief or extension of the spine.
• This process can be repeated any number of times, i.e. by successively moving the axillary supports up and down, a large number of successive relief processes can be carried out.
• the armrests are mounted on the backrest of the seat so that they can be plugged in or screwed on.
• the axillary supports are removed by manual pulling or unscrewing after use, while the use is made by inserting or screwing on.
• a further embodiment of the invention is characterized in that the armpit supports can be folded into and out of the backrest plane. Folding in or out can also be done manually, but also automatically with the aid of a suitable drive, which in turn is controlled by a control device, for example corresponding pressure buttons that can be operated.
• Another embodiment of the invention provides for the axillary supports to be countersunk into the backrest.
• the seat user takes this place. He then actuates the control device so that the axillary supports are folded out of the level of the backrest and protrude from it. The user can then place his arms around or on the armpits so that they contact the armpits or arms of the user. By further actuating the control device, the axillary supports can be moved in the lateral or vertical direction until a corresponding spinal relief effect is achieved.
• the axillary supports are arranged on the side walls of the backrest. As mentioned, they are preferably arranged to be adjustable, the adjustability being, for example, with
• the axillary supports are expediently designed to be foldable, whereby they are folded out of the level of the backrest in order to reach the position of use.
• the axillary supports are arranged on the front of the backrest, in particular they extend through recesses in the front of the backrest. These recesses are preferably so large that they allow the position of the axillary supports to be adjusted in the horizontal and vertical directions. It goes without saying that the front of the backrest can be provided with a corresponding cushion, for example, recesses is spared.
• the armpit supports or armpit support supports can be installed directly in the respective seat or added to the respective seat as an additional device, for example by plugging, screwing, clamping, etc. They can also be arranged on a seat cover or a seat frame, which or which is placed on a corresponding seat and, if necessary, fixed thereon.
• a preferred embodiment of the invention is characterized in that the axillary supports are arranged movably in the lateral direction on a common support which is mounted so that it can be moved up and down.
• the carrier can be T-shaped, the vertical leg forming part of the device for up and down movement.
• the carrier is expediently guided via at least one guide to carry out an up and down movement.
• the lateral movement of the armpits is preferably carried out via an endless belt, an endless chain or an endless rope, which is guided around two pulleys.
• the supports are fastened to the endless belt, preferably one at the lower section and one at the upper section of the endless belt guided over the deflection rollers, so that when the belt moves in one direction both
• Supports are guided inwards or outwards.
• the axillary supports can be movably mounted in corresponding guides in order to achieve a fixed but laterally displaceable position.
• the up and down movement of the carrier is preferably carried out via a rack and pinion drive or a gas spring mechanism.
• the armpits are in the manner of shelf elements with the help of Locking pins fixed in elements provided with corresponding locking holes.
• the plug pins here preferably have a rear angled section, which lies against the rear side of the support element and thus enables the axial support to be loaded from above.
• the entire supporting element can be designed to be movable or displaceable in the lateral and / or vertical direction, so that corresponding adjustment options for the axillary supports also result here.
• the armpit supports can extend through recesses in the front of the seat back.
• lateral recesses can also be arranged in the front of the seat backrest, in the area of which the two armpit supports are located, so that they can be adjusted there.

Of course, a remote control device can also be used. The seat user can thus comfortably carry out a corresponding adjustment of the arm supports in the lateral direction and move the arm supports up and down.
