    To this end, the invention is based on the said stand having both the adjustable back portion and the headrest device mounted on the said adjustable back portion, the length of a headrest shell mounted on the said headrest device self-adjusting to adapt to the person's head position which changes continuously depending on the current installation. sates party and back party.
    The invention is further based on the said capital device, which enables a quick installation to the operating room and can handle a sufficient load and occupy a low installation height. The space under the said back portion becomes as spacious as possible, which together improves the ergonomics of a surgeon and assistant staff using the operating table. . The invention is further based on handling different weights on the head shell shells whose design may look different in different markets or look different for different treatments where said head shell shells angles can be set on an electrical or mechanical wall.
    Although the present invention has emerged in connection with an operating table Mom ogon surgery, with the ddr assigned different seas to aft create a for users weightless capital device, it stands, at least RV a professional Mom this technical field, clearly aft said capital device much choice can get a application in other areas of application where the head needs to be fixed and a back portion can be aliases such as operating tables, bunks or chairs for surgical procedures or treatments around the head as in drone-ndsa-throat, facial plastic surgery, dental surgery and the like. Other purely surgical attachments may be for wheelchairs and similar aids where the head was provided which accompanies the movement of the heads as needed.
    The invention comprises a capital device provided with a capital belt which is stored with low friction, a counterweight which is stored with low friction where said capital shaft and counterweight run parallel on top of each other connected to a belt or the like for power transmission where said belt runs on an over belt bearing and a lower belt bearing fixed in the headrest device.
    The invention relates to a headrest device to which a headrest shell is hingedly and fixably connected. The headrest device is connected to a back portion hingedly connected to a seat portion on a treatment table, preferably an operating table. The headrest device is steplessly and autonomously longitudinally displaceable in relation to the supine portion only under the influence of a person with a sifted head placed in the headrest shell and resting against the treatment table near the back of the treatment table other angles in relation to the seat part. This autonomous displaceability comprises a storage of the longitudinal movable parts, the viii saga including the headrest device with the headrest shield.
    In one embodiment of the invention, the headrest device is provided with a weight balancing means. Because the longitudinally displaceable parts can weigh up to 10 kg, some form of weight balancing is necessary to avoid unpleasant force on the patient during the said angular change or because the said displaceable parts are not displaced longitudinally by their own weight if the patient for some reason wishes to adjust position and lifts the head.
    Such a weight balancing means must thus compensate for the inherent weights of the parts.
    In an embodiment of the invention, the weight balancing means comprises a counterbalance magazine connected to the capital device by means of a power transmission means and a capital cable stored for linear reciprocating movement in a bar means for the capital device. The power transmission means may be constituted by a belt, for example a toothed belt, a rope, a wire or the like which is Wig luing one or more stored breaking rollers to effect movement in two opposite directions. The counterweight magazine can easily be adjusted in terms of weight by adding or removing weights in order to adjust the counterweight magazine to the exact mass that needs to be balanced, ie the components connected to the headrest device.
    In one embodiment of the invention, the power transmission means consists of a belt which scratches over an upper layer and a lower layer. This embodiment entailed a simple explanation of the connection of the headrest cable and the counter-magazine to the power transmission means.
    In an embodiment of the invention, the headrest shell is hingedly and fixably connected to an adjusting arm which is fixedly connected to a rotation shaft which is mounted in the headrest device. This embodiment entailed a complementary installation option for the height of the head in relation to the back portion.
    In an embodiment of the invention, the axis of rotation is provided with a sea arm hingedly connected to a longitudinal arm which is connected to an electrical stable device for a substantially axial action on the longitudinal arm and an angular rotation on the axis of rotation. This embodiment involved an electrical angular installation of the head bearing before the actual treatment. An electrical installation can be done with the help of a foot pedal whereby the hands of the treating person, for example the doctor, are free.
    The invention further relates to a back portion of a treatment table, preferably an operating table, wherein a headrest device is connected to the back portion so that the headrest device is completely or partially infantly mounted in a recess in the back of the back portion. The head restraint device which is recessed in the recess is designed as described in this application. The advantages of such a recessed headrest device are that the treating person must be offered as much space as possible under the back part, at the same time as the headrest device must not be an obstacle in the treatment work.
    In an embodiment of the invention, the back portion is articulated and steplessly fixably connected to a side portion of the treatment table. This means that several treatment days can be set for an optimal treatment mode depending on the type of treatment. The articulation of the back part entails a force effect on the patient's head, neck and shoulder part, which force force is considerably reduced when the back part is combined with the previously described headrest device.
    In an embodiment of the invention, the back portion is steplessly fixable in any position in relation to the seat part.
    The invention also relates to a treatment table, preferably an operating table, comprising a leg portion, a seat portion and a back portion which portions are hingedly connected to each other and whose inward angles can be set. A headrest device is connected to the said back portion. This headrest device is designed as described in this application.
    Embodiments of the invention also comprise a stable device for the main body device, which can electrically or hydraulically mesh the angle of the main body shell in relation to the main body wire.
    The invention also makes it possible for the headrest device to consist of a completely free-standing unit, which can only be mounted by and on the back portion for disinfection and / or switching between different types of headboard wedges.
    The invention also makes it possible for different types of headrest shells and accessories to be mounted on the headrest device, regardless of its separate weights, whereby the device can still be perceived by a patient or surgeon as weightless or floating.
    Although the present invention is intended to be applicable to each type of stand, the following exemplification of the application of the invention will only focus on an operating table stand.
    It will then be emphasized at the outset in the following description, over a present four-stroke embodiment, which shows the 7 pitches significant with the invention and which is clarified by the figures shown in the following drawings, we have chosen terms and a special terminology for that purpose. aft thereby in the first place let clarify the inventive side.

    Figure 3 shows the back portion 13 with the headrest device 19 and the headrest shell 18. The headrest device 19 is connected to a support member 31 via a movable headrest cable 32 which is arranged with guides which are stored for reciprocating movement in the support member 31. The bar member is further mounted in a recess 33 provided on the rear side of the back portion 13 in order to eliminate in some way protruding parts of the bar member 31.
    Figure 4 shows the bar member 31 with the headrest device 19 mounted on the headrest shield 32 where these parts are exposed from the back portion shown in figure 3. Mounted on the carrier means is an electric stable 41 which acts as a linear motor which can displace a jug 42 back and forth. The lance arm 42 is hingedly connected to a sea arm 43 which is fixedly connected to the main body device 19 via a rotation shaft 44, a displacement of the lance arm 42 providing an angular landing of the capital device 19 and thereby a curved angular layer of the capital shell.
    Figure 5 shows the movable capital sled 32 which is coordinated with a counterweight 51 so that the capital shell should be perceived as weightless regardless of the angle at which the back portion is installed. The capital sled 32 and the counterweight 51 are connected to each rudder side 521, 522 of a power transmission member 52. Preferably in the form of a strap, in such a way that the counterweight 51 moves in the opposite direction to the headrest cord 32 and thus balances its weight. Saval counterweight 51 which the main body sled 32 stored there for forward and backward movement in the bar member 31. In one embodiment, the power transmission member 52 is breathless and running around an upper bearing 53 in the bar member and around a lower bearing 54 in the support member 31 with the head sled and the counterweight respectively connected to different As shown in Figure 5, the counterweight 51 is divided into several subweights 511, 512, 513 which can be detached or added and which can also be of different weights in order to correctly balance different constellations of connected parts to the main body 32. The bar member 31 is further provided with weight steamers intended aft in the external breath contribute to a smooth stop of the counterweight 51 movement. A handle 55 is arranged at the lower end of the bar member 31, which handle has a spring-loaded speed which makes the entire headrest device 19 easily detachable from the back portion. The figure also shows the lance arm 42 connected to the sea arm 43 and mounting bracket 56 in the lintel arm 42 and mounting hall in the capital cable 32 for mounting the stable device removed in the figure, which is shown in figure 4.
    Figure 6 shows a weight balancing means 61 which includes the counterweight magazine 62 with the previously shown counterweight, the power transmission means 52 and the main body sling 32. The power transfer means 52 is thus connected between the counterweight magazine 62 and the main body device 19 with the main body sled 32. The main body is folded. lines forward and reciprocating movement in the bee member flir the headrest device 19.
    Figure 6 also shows that the headrest shell 18 is connected to the headrest device 19 via an adjusting arm 63 which is fixedly connected to the headrest device 19 but rotatable and weldable in relation to the headrest shell 18. Through this adjusting arm the height and angle of the headrest shell 18 relative to the headrest shield 32 and the angle of the main body shell 18 is manually smoothed by means of a control knob 64.
    Within the framework of the invention, the design of the weight balancing means of the weight balancing means can be modified and may, for example, consist of a line running over line wheels.
