Description

The present invention relates to a height-adjustable neck support system for an office chair, in particular for an e-gaming chair, for adapting to different head and neck support heights of users of different sizes, and a chair with such a system.

Gaming chairs, also known as eGaming chairs, are becoming increasingly popular. A gaming chair is a desk chair that is used to play computer games. The gaming chairs are given a sporty and eye-catching design thanks to a special look and presentation.

A separate head and neck pillow and a separate lumbar cushion are clear signs of gaming chairs. Like office chairs, gaming chairs usually have seat height adjustment, armrests and a rocker mechanism that can be locked if necessary. The seating comfort of gaming chairs is often many times higher than that of classic desk chairs, which is due to the special cushions (source: www.stern.de).

The (separate) neck pillow is usually pulled vertically over the upper area of the back of the chair by means of elastic loops (e.g. rubber bands) that are firmly attached to the pillow. The upper area of the backrest is typically tapered towards the top in order to function as a headrest. With the elastic, horizontally circumferential loop, the neck pillow can be attached to the chair at the desired height.

The disadvantage here is that the horizontal and vertical position of the neck pillow can change during use. This changes an optimal position previously set by the user into an (ergonomically) bad position. The user feels the (unintentional) change in position of the neck pillow disturbing. This can mean that the user has to interrupt his current activity in order to reposition the neck pillow or optimally again.

As already explained above, the gaming chairs are also characterized in particular by their striking appearance. Due to the unstable positioning, it can happen that the neck pillow covers optically relevant (decorative) areas of the backrest, so that, for example, the logo of the chair manufacturer is no longer visible. This is undesirable. In addition, light sources integrated into the chair, which are not uncommon in gaming chairs, can be covered by the neck cushion.

It is therefore desirable to provide a neck support which can be fixed to the chair in a stationary manner (also subsequently in the sense of a retrofit kit). In particular, a height adjustment is desired that covers a larger adjustment range than conventional (fixed) neck supports. The desired expansion of the adjustment range should preferably not result in functionally relevant areas of the chair being covered.

This object is achieved by a height-adjustable neck support system for an office chair, in particular for a gaming chair, for adapting to different neck support heights of users of different sizes, which has: a neck support which has a supporting edge; a holding plate which is adapted to be fixedly attached to the chair; and an adjusting mechanism which comprises a first adjusting device and a second adjusting device, wherein the first adjusting device is connected to the neck rest and the second adjusting device is connected to the holding plate and wherein the adjusting devices define a length of an adjusting range when the adjusting devices are in a state of engagement with one another Are engaging; wherein the adjusting devices can be brought into engagement with one another in such a way that the neck rest can be connected to the holding plate in a first orientation and in a second, opposite orientation; wherein the adjustment devices are set up to be moved relative to one another in opposite adjustment directions; and wherein the support edge, when the neck rest is positioned centrally in the adjustment area, is arranged eccentrically with respect to the adjustment area.

The neck support can be connected to the retaining plate in two opposite orientations. Since the support edge is arranged off-center, the support edge can be adjusted in a larger adjustment range when the neck support is oriented in the opposite direction than would be possible with a single orientation of the neck support. Thus it is possible that very small users and very tall users can use the same headrest by rotating the orientation of the headrest. Nevertheless, the maximum area that is covered by the neck support system with maximum deflections of the neck support upwards and downwards with respect to the holding plate - with the position of the holding plate unchanged - does not change. This means that relevant areas of the chair are not covered, although the height adjustment range for the neck support has been expanded.

The length of the adjustment range is preferably a maximum or maximum possible offset of the adjustment devices in the opposite adjustment directions.

In other words, this generally means that the longer at least one of the adjustment or latching devices - compared to other adjustment or latching devices - is designed, the larger the adjustment range and the greater the expansion of the adjustment range, in particular the further off-center the headrest edge of the neckrest is positioned.

In an advantageous embodiment, the support edge in the first orientation of the neck rest, during a maximum offset of the adjustment devices in the engaged state in one of the adjustment directions to each other, is positioned further away from a center of the adjustment range than in the second orientation during the maximum offset of the adjustment devices in FIG same direction of adjustment.

The adjustment mechanism preferably comprises at least one forced guidance element, so that the adjustment devices are positively guided in the adjustment directions.

The positive guide elements have the effect that the neck support can only be moved along desired directions relative to the holding plate. The positive guide elements also have the effect that the neck rest can be attached to the holding plate in a captive manner.

In particular, the adjustment devices are designed as latching devices.

One of the latching devices can preferably comprise toothed racks which are arranged at a distance from one another and which extend parallel to the longitudinal extent of the neck rest.

The extension of the racks define the adjustment directions. The racks are therefore preferably oriented parallel to the longitudinal extension of the neck support.

A pitch of the teeth defines an adjustment interval.

Two racks are provided in order to be able to move the neck support in both orientations (stepwise or stepwise).

The other of the latching devices preferably defines an elastically mounted latching lug, which in particular comprises an (omega-shaped) spring plate.

The locking lug engages in the racks and thus enables a gradual adjustment of the neck rest relative to the retaining plate according to the pitch of the teeth of the racks. The spring plate is preferably omega-shaped so that the protruding part of the spring plate engages resiliently in the valleys of the rack. In this case, the locking lug is pretensioned in the direction of the valleys of the racks.

Furthermore, it is advantageous if the neck support has a support body, the support edge extending parallel to a width direction of the neck support and protruding furthest out of the support body in a depth direction, the width direction being oriented horizontally when the system is attached to the chair.

In particular, a cross section of the neck rest in a plane perpendicular to the width direction corresponds to an unequal triangle.

The shape of the non-isosceles triangle results in the eccentric arrangement of the support edge when the latching device extends along the hypotenuse of the triangle.

The first adjusting device is preferably arranged on a side of the neck rest which faces the retaining plate in the engaged state, and wherein the supporting edge is disposed on a side of the neck rest which faces away from the retaining plate in the engaged state.

In the engaged state, the neck rest lies flat against the holding plate. The adjustment devices are inaccessible and not visible to the user, so that there is no risk of injury and an aesthetically pleasing overall impression is created when the system is installed.

In particular, the holding plate comprises a bottom section and an edge section which are shaped such that the holding plate can be inserted into the chair in a form-fitting manner.

The form fit enables the retaining plate to be inserted into the chair. Fixing rubber bands, Velcro fasteners and the like can be dispensed with.

The form fit ensures the fixed orientation of the retaining plate on the chair.

There are no aesthetically disturbing straps.

Furthermore, it is preferred if the second latching device is arranged on the bottom section of the holding plate.

In a particular embodiment, the holding plate is shell-shaped so that the edge section is oriented obliquely, preferably perpendicularly, to the floor section, and a contour of the floor section and / or a contour of the edge section to a contour of an upholstery space of the chair and / or to a contour another chair element is adapted.

By adapting the contours, the overall aesthetic impression is further enhanced. The system is mounted on the chair without any visually disturbing elements. The neck support lies directly against the chair and thus appears in a form integrated into the chair.

Preferably, the adjustment mechanism further comprises a safety mechanism, which is arranged in particular at at least one end of the adjustment range and which is activated in a normal state and mechanically limits the adjustment range, wherein the safety mechanism can be deactivated by the user in order to move the adjustment devices over the To bring the adjustment range out of engagement for a change in the orientation of the neck support.

In particular, the adjustment directions are oriented parallel to a longitudinal extension of at least one of the adjustment devices, with a length of at least one of the adjustment devices preferably defining the length of the adjustment range.

Furthermore, the above-mentioned object is achieved by a chair with a corresponding neck support system, the contour of the retaining plate in particular being adapted to the contour of the chair for the form-fitting, fixed positioning of the system on the chair.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination, but also in other combinations or on their own, without departing from the scope of the present invention.

Exemplary embodiments of the invention are shown in the drawing and are explained in more detail in the following description. Show it:

• 1 a perspective view of a gaming chair with a mounted neck support system;
• 2 a perspective view of the gaming chair of FIG 1 without the neck support system;
• 3 an exploded view of a front of a neck support system;
• 4th an exploded view of a rear side of the neck support system of FIG 3 ;

In the perspective view of the 1 is a gaming chair 10 with a height-adjustable neck support system 12th shown in an upper region of a backrest 14th on the chair 10 is attached. the 2 shows the chair 10 the 1 without the system 12th .

The Cartesian coordinate system of all 1 until 9 is spanned by a height direction H, a width direction B and a depth direction T. One height of the chair 10 and the system 12th extends along the height direction H. A depth of the chair 10 and the system 12th extends along the depth direction T. A width of the chair 10 and the system 12th extends along the width direction B. In the 1 is the system 12th shown in a use situation, ie in an assembled state. The directions H, B and T are particularly with respect to a seat back 14th Are defined.

The height-adjustable neck support system 12th generally has a neck support 16 and a holding plate 18th on. Optionally, the system 12th also a (fabric) cover 20th have, for reasons of hygiene, over the neck support 16 can be drawn, cf. 3 and 4th . On the reference 20th will will not be discussed in more detail below, as it is irrelevant for height adjustability. The system 12th will therefore be given below with particular reference to the neck support 16 and the holding plate 18th are described in more detail.

3 Figure 3 shows an exploded view of the system 12th in a front view. the 4th Figure 3 shows an exploded view of the system 12th the 3 in a rear view. the 5 Figure 3 shows a perspective view of the system 12th the 3 and 4th in an assembled (engaged) state.

The neck support 16 is wedge-shaped and has a support body (cushion, for example made of foam) and a base plate (optionally provided separately), cf. 7th .

The neck support 16 generally defines a supporting edge 22nd (see dashed line in 3 ), which a user (not shown here) can contact while using the chair 10 , so when sitting, can support his neck with his head in an area above the supporting edge 22nd to discard. The wedge shape of the neck support 16 is preferably concave along the width direction B in order to accommodate the neck as ergonomically as possible (ie in particular in a form-fitting manner). In a plane that is spanned by the height direction H and the depth direction T, the neck support 16 has a triangular cross-section which corresponds to a non-isosceles triangle, as will be described below with reference to FIG 8th and 9 will be explained in more detail.

The system also includes 12th an adjustment mechanism 24 , the at least two adjustment devices 25th , in particular as locking devices 26th are formed, having. The adjustment mechanism 24 can be equipped with a handwheel, for example, latching (stepwise), steplessly (not shown) or via a gear (not shown). The adjustment devices 25th could, for example, also be designed as a slot-slot nut connection, as a magnetic strip-magnet block connection or as a similar connection made of elements that correspond to one another. In the following, a step-by-step locking mechanism is assumed as an example.

The adjustment mechanism 24 has in particular a first latching device 26-1 and a second latching device 26-2, the first latching device 26-1 being, for example, elongated and with the neck support 16 is connected (cf. 4th ) and wherein the second latching device 26-2 is formed, for example, point-like and with the retaining plate 18th is connected (cf. 3 ). The latching devices 26-1 and 26-2 can be brought into engagement with one another (in a longitudinal direction) in such a way that the neck rest 16 with the retaining plate 18th permanent and releasable in a first orientation O1 and in a second opposite orientation O2 (cf. 8th ) is connectable.

In general, the adjustment devices 15 and in particular the latching devices are 26th set up, in opposite adjustment directions R1 and R2 (cf. 7-9 ), which are parallel to a longitudinal extension of at least one of the locking devices 26th , here the latching device 26-1, are oriented within an adjustment range Vges (cf. 9 ), preferably in stages, to be moved relative to one another.

The neck support 16 is rotated by 180 °, as shown in 4th is illustrated by an arrow in order to move from the first orientation O1 (cf. 8th , left) in the second orientation O2 (cf. 8th , right). When the orientations O1 and O2 are changed, the latching devices 26-1 and 26-2 are disengaged around the neck rest by being different from one another, as will be explained in more detail below 16 to be able to rotate accordingly in the separated state, so that the latching devices 26-1 and 26-2 can then be brought back into engagement with one another by sliding them into one another. It goes without saying that the rotation by 180 ° can also be implemented differently. The neck support 16 could for example also be permanently (and captive) with the retaining plate via a swivel joint (not shown) 18th be connected. In this case, the neck support can be used 16 Turn 180 ° without the headrest 16 from the holding plate 18th to separate. The user pulls on the neck support, for example 16 , brings the adjustment devices 25th (not shown) disengaged in this way while the neck support 16 permanently with the retaining plate 18th remains connected, the prop rotates 16 and then pushes it back into the holding plate in the opposite direction 18th in to the adjustment devices 25th to re-engage.

6th shows a perspective view of the retaining plate 18th the 3 until 5 . The holding plate 18th is shown in isolation. The holding plate 18th is preferably an injection molded part from plastic.

The holding plate 18th is cup-shaped. The holding plate 18th is from a floor section 28 and an edge portion 30th educated. The bottom section 28 is preferably designed as a flat surface. The edge section 30th stands out of the plane of the floor section 28 before. The edge section 30th is inclined, in particular perpendicular, to the plane of the bottom section 28 oriented. The edge section 30th is C-shaped here, if you look perpendicular to the back of the retaining plate 18th looks. It goes without saying that a contour 40 of the edge section 30th could also be different. The edge section 30th could, for example, consist of two separate, mutually parallel spaced sections, ie of the connecting vertical section of the C-shape, but which are nevertheless along the contour 40 extend.

In common parlance, the “contour” of an object is a curve or a curve that separates the object from its surroundings for an observer. The contour of an object depends not only on the shape of the object itself, but also on the direction from which the observer is observing the object. In the present text, the term “contour” is not (only) to be understood in the classic sense of an (outer) contour line. A “contour” can also be defined by a dividing line between adjacent objects (e.g. upholstery), as is exemplified below for spaces between upholstery 42 will be explained.

It is preferred, as will also be explained in more detail below, that the contour 40 of the edge section 30th with a contour 36 the spaces between the upholstery 42 (see. 2 ) of the chair 10 corresponds to by inserting the retaining plate 18th , especially the edge portion 30th , in the spaces between the upholstery 42 a form-fitting connection between the chair along the depth direction T. 10 , especially the backrest 14th , and the retaining plate 18th in the height and / or width direction H and B to be generated. By a suitable choice of a cross section of the edge section 30th and through a suitable choice of upholstery 38 (Elasticity) can be the edge section 30th force-fit (in the depth direction T) in the spaces between the upholstery 42 be releasably fixed.

In the present example, the second latching device 26-2 is with the retaining plate 18th tied together. In the 6th only a part of the second latching device 26-2 is shown, which is set up to receive a spring steel sheet (not shown here) (with an omega-shaped cross section). The spring plate is in the exploded view of the 3 illustrated.

This recording for the spring plate is in the 6th preferably in one piece with the retaining plate 18th educated. It goes without saying that the latching device 26-2 can also be provided separately and in a different manner (for example by means of an adhesive) with the holding plate 18th can be connected.

The latching device 26-2 is on a front side 32 the retaining plate 18th arranged. The front 32 is in an engaged state of the locking devices 26th (see. 5 ) to the headrest 16 turned towards. A back of the retaining plate, not designated here in more detail 18th is in an assembled state of the system 12th (see. 1 ) to the chair 10 turned towards.

The edge section 30th is shaped so that the retaining plate 18th form-fit in the chair 10 is pluggable, as it is in the 1 is shown. The edge section 30th optionally has nose sections that act as barbs so that the retaining plate is attached 18th not so easy from the chair 10 solves.

One contour 34 of the bottom section 28 (in a top view of the retaining plate 18th ) in the 6th is indicated with a dash-dotted line, is on a contour 36 a (multi-part) upholstery 38 of the chair 10 customized. The contour 34 of the bottom section 28 in turn defines a course - and thus also a contour 40 - the edge section 30th (in a view from below of the retaining plate 18th ), as mentioned above.

The upholstery 38 of the chair 10 consists of several parts 39 , e.g. from parts 39-1 to 39-4, the corresponding padding spaces 42 (see. 2 ) define between themselves. The upholstery spaces 42 define the congruent contour 36 and are dimensioned in such a way that they can preferably completely accommodate the edge section 3 (in the depth direction T). The upholstery 38 is made of an elastic material that plugging (immersing) the edge portion 30th allows and the edge section 30th in the inserted state non-positively (in the height and / or width direction H and / or B) holds, so that the retaining plate 18th is releasably fixed in the depth direction. It goes without saying that the parts 39 can be made of different materials with different elasticities. It is also possible that some of the parts 39 are not padded at all. However, at least one of the adjoining parts is preferably 39 upholstered, the space or spaces between the upholstery 42 define. As a further alternative it is possible that all parts 39 are unpadded and the edge section 30th has a corresponding elasticity.

So it goes without saying that the contours 34 , 36 and 40 are adapted to one another that the retaining plate 18th form-fit in the spaces between the upholstery 42 is pluggable. The bottom section 28 could also have a larger area than illustrated, so that it extends over the edge section 30th extends beyond (not shown).

It is also understood that the holding plate 18th also different, ie without a form fit, stationary with the chair 10 can be connected. For this purpose the chair could 10 For example, snap fasteners, Velcro strips or the like, not shown here, preferably in the upper area of the backrest 14th exhibit. The holding plate 18th is in this case with corresponding elements (not here shown) provided to the fixed connection between the retaining plate 18th and the chair 10 to manufacture.

In general, the adjustment mechanism 24 also one or more forced guidance elements 44 may include. The forced guidance elements 44 serve to one, several or all locking devices 26th forcibly guided along the adjustment directions R1 and R2. The forced guidance elements 44 cause the locking device 26th are only movable along the adjustment directions R1 and R2 and the connection between the neck support 16 and the retaining plate 18th is secure against loss.

In the 6th are several positive guide elements 44 shown coming from the front 32 of the bottom section 28 protrude. Two, for example, pin-shaped positive guide elements 44-1 and 44-2 are arranged centrally with respect to the width direction B and are arranged at a distance from one another in the height direction H. Two further positive guide elements 44-3 and 44-4 are arranged on the outside in the width direction B. The positive guide elements 44-3 and 44-4 each have an L-shaped cross section along the height direction H. The positive guidance elements 44-1 to 44-4 are positioned relative to one another in such a way that they are connected to further (not shown here) positive guidance elements 44 cooperate on the neck support 16 are arranged as referring to 7th will be explained in more detail. The relative positioning and shape of the forced guidance elements 44 the retaining plate 18th depends on the position and shape of the positive guide elements 44 the neck support 16 adapted in such a way that the desired forced operation is brought about. It goes without saying that the in 6th Shown arrangement and shape of the positive guide elements 44 can also be chosen differently.

It is also generally true that the adjustment mechanism 24 a safety mechanism 46 may include. The safety mechanism consists of one or more safety elements 48 attached to the neck support 16 and / or on the holding plate 18th are arranged.

In the 6th a securing element 48-1, for example mounted in a rocker-like manner, is shown, which is located in an opening in the bottom section (not designated here in greater detail) 28 the retaining plate 18th is arranged. The securing element 48-1 is arranged in the width direction B between the centrally arranged constrained guide element 44-2 and the externally arranged constrained guide element 44-3. The fuse element 48-1 is from the front 32 along the depth direction T and is pivotable about an axis of rotation, not shown in detail here, which extends parallel to the width direction B, as indicated by an auxiliary arrow in FIG 6th is indicated.

In the 6th some areas are shown hatched. The hatched areas illustrate sliding and bearing surfaces with the locking devices 26th , the forced guidance elements 44 and the securing elements 48 the neck support 16 cooperate as it is below with reference to 7th will be explained in more detail.

7th Fig. 13 is a perspective view of a rear side 50 the neck support 16 , see also 4th . The backside 50 can be made in one piece with the neck support 16 be designed or as a separate base plate 52 be implemented on which a padding (support body) to form the neck support 16 can be attached.

In the 7th are also the first latching device 26-1, positive guide elements 44 and securing elements 48 shown that of the neck support 16 assigned.

The first locking device 26-1 of the 7th is formed by two racks 54-1 and 54-2. The racks 54-1 and 54-2 extend parallel and spaced apart from one another essentially along the depth direction T in the 7th . The racks 24-1 and 24-2 are on an elongated forced guidance element 44 mounted on the side so that the teeth of the racks 54 are aligned in the width direction B. The constraining guide element 44-5 interacts with the pin-shaped constraining guide elements 44-1 and 44-2 of the holding plate 18th (see. 6th ), which engage in a centrally arranged groove of the positive guide element 44-5 and ensure a sliding bearing there. Like in the 6th are also in the 7th Sliding and bearing surfaces of the neck support 16 shown hatched.

The teeth of the racks 54-1 and 54-2 are arranged in such a way that they are connected to the spring plate of the second latching device 26-2 (cf. 3 ) come into engagement with a detent. The second latching device 26-2 defines a latching lug which is in spaces between the teeth of the racks 54 (resiliently) engages the locking devices 26th to move gradually against each other by a movement along the adjustment directions R1 and R2. It goes without saying that only one of the toothed racks 54-1 and 54-2 is in engagement with the detent, depending on the orientation of the neck rest 16 relative to the holding plate 18th . But this also means that the back 50 with respect to the first latching device 26-1, the positive guide elements 44 and the securing elements 48 are arranged symmetrically to a central axis, which is in the 7th extends centrally in the width direction B and parallel to the height direction H. This axis of symmetry is in the 7th indicated by a dashed line.

In addition to the centrally arranged constrained guide element 44-5, further constrained guide elements 44-6 and 44-7 are provided. The constraining guide elements 44-6 and 44-7 are arranged offset in the width direction B outwardly in relation to the constraining guide element 44-5. The positive guide elements 44-6 and 44-7 each extend essentially along a longitudinal extension of the neck rest 16 , ie in the 7th parallel to the height direction H. The positive guide elements 44-6 and 44-7 of the neck rest 16 act with the L-shaped (outer) positive guide elements 44-3 and 44-4 on the retaining plate 18th (see. 6th ) together. The positive guide elements 44-6 and 44-7 also have, for example, an L-shaped cross section that emerges from the rear 50 protrudes in the depth direction T. It goes without saying that the positive guide elements 44-3, 44-4, 44-6 and 44-7 are adapted to one another with regard to their dimensions.

Furthermore, the neck support 16 the 7th two securing elements 48-2 and 48-3, which with the securing element 48-1 of the neck rest 16 the 6th cooperate. The fuse elements 48-2 and 48-3 are in an outer area of the rear 50 the neck support 16 arranged and spaced from one another in the width direction B. The securing elements 48-2 and 48-3 protrude from the rear 50 in the depth direction T and are resilient in the rear 50 stored to with the securing element 48-1 of the retaining plate 18th in the event of a change in the orientation of the headrest 16 to be depressed. When pressing down, the safety elements 48-2 and 48-3 are manually brought to the level of the rear by the user 50 lowered so that the neck support 16 by a movement in the adjustment direction R1 from the holding plate 18th can be separated. In normal operation, the securing elements 48-2 and 48-3 serve as stops for the racks 54 who have disconnected the neck support 16 from the holding plate 18th prevented by a movement along the adjustment direction R1.

A length of racks 54 and / or a position of the securing elements 48-2 and 48-3 in the height direction H define a length of a maximum possible adjustment range that is associated with the 9 will be explained in more detail and which is denoted by Vges.

8th serves to illustrate the two different orientations O1 and O2 that the neck support 16 in relation to the retaining plate 18th can take, which is stationary and with an unchanged orientation on the chair 10 is to be attached. In the 8th is the neck support 16 schematically in the form of the first latching device 26-1, and in particular in the form of the rack 54 , as well as in the form of the support body with the triangular cross-section. The holding plate 18th is shown schematically exclusively in the form of the second latching device 26-2.

The locking devices 26-1 and 26-2 are in the 8th shown in a normal position. In the normal position, the locking devices 26-1 and 26-2 are exactly in a center (H0) of the adjustment range Vges. The adjustment range Vges is defined in the deflection directions R1 and R2 by a maximum offset of the locking devices 26-1 and 26-2. The maximum offset is in 9 for the orientations O1 and O2 of the neck support 16 shown. The orientations O1 and O2 of the neck support 16 differ in that the supporting edge 22nd in a lower section (orientation O1) of the neck support 16 or in an upper section (orientation O2) of the neck support 16 is positioned. The neck support 16 can be switched between orientations O1 and O2 by using the neck support 16 from the holding plate 18th is removed and turned 180 before the headrest 16 is reinserted into the holding plate 18, including no active actuation of the securing elements 48 is necessary because the securing elements 48-2 and 48-3 are beveled accordingly (cf. 7th ).

The orientation O1 is in the 8th shown on the left. The orientation O2 is in the 8th shown on the right.

In the normal position, the locking devices 26-1 and 26-2 (with their respective centers) are each at the level H0. The support edge is in orientation O1 22nd arranged lower than in orientation O2.

In the 9 are the various extreme positions P1-P4 of the neck support 16 made clear. The headrest is in positions P1 and P2 16 in the orientation O1, ie the supporting edge 22nd is in a lower area of the neck support 16 arranged. The headrest is in positions P3 and P4 16 in orientations O2, ie the supporting edge 22nd is located at the top of the neck support 16 .

The headrest is in position P1 16 in the orientation O1 deflected maximally in the adjustment direction R2. The position P1 defines the highest position that the supporting edge 22nd can take in the orientation O1. The latching devices 26-1 and 26-2 are maximally offset from one another (in the direction R2).

The position P2 shows the lowest point that the support edge 22nd can take when the neck support is on 16 is in orientation O1. In this case, the latching device 26-1 is the neck support 16 offset maximally in the direction R1 with respect to the latching device 26-2.

In general, it goes without saying that the second latching device 26-2 - via the assembly of the retaining plate 18th on the chair 10 - Is stationary, and in particular does not change its orientation.

In the orientation O2, the position P3 again shows the lowest position of the support edge 22nd and the position P4 the highest position of the support edge 22nd . The highest and lowest positions are in the 9 indicated by Hmax1, Hmax2, Hmin1 and Hmin2.

A size of the (entire) adjustment range Vges is independent of the orientation O1 or O2 of the neck support 16 . A comparison of the orientations O1 and O2 clearly shows that the neck support 16 is always adjustable by the same distance maximum in the directions R1 and R2.

In relation to the normal position, the (entire) adjustment range Vges is composed of two sub-adjustment ranges V1 and V2, which in turn are determined by the adjustment directions R1 and R2.

As already indicated above, a length L _{v of} the adjustment range Vges is essentially determined by a length L _R of at least one of the latching devices 26th certainly. In the present case, this is twice the length of the first latching device 26-1, ie the length of the toothed rack (s) 54, which is much greater than an extension of the latching lug of the second latching device 26-2 (in the height direction H), minus the length of the second latching device 26-2.

It goes without saying that the locking devices 26-1 and 26-2 with regard to their positioning on the neck rest 16 and the retaining plate 18th could also be swapped. Nevertheless, the length L _{v of} the adjustment range would be Vges through the length of the locking devices 26th to be determined.

9 shows that an adjustment range (in the height direction H, if the system 10 on the chair 10 is mounted) due to the off-center arrangement of the supporting edge 22nd is significantly enlarged. In other words, this means that Vges is greater than V1 and greater than V2. Nevertheless, the system hides 12th (maximum) the same area of the chair when a viewer whose eye is in the 9 is indicated on the left, along the depth direction T onto the system 12th looks.

The off-center arrangement of the supporting edge 22nd is determined by the cross section of the neck support 16 (in the TH level). The cross section is an unequal triangle, making the supporting edge 22nd off-center with respect to the locking device 26th which essentially determines or co-determines the length L _{v of the adjustment range Vges.}

In particular, positions P2 and P4 are advantageous because position P2 is suitable for very small users and because position P4 is suitable for very tall users. Conventional neck pillows would be used to adapt to different body sizes in a different place on the chair 10 be attached. In the system disclosed here 10 this is not necessary. The holding plate 18th remains at the same location, including a coverage area of the system 10 does not change, despite an extended adjustment range Vges.
