Definitions

  • the present invention relates to a height-adjustable neck support system for an office chair, in particular for an e-gaming chair, to adapt to different head and neck support heights of users of different sizes and a chair with such a system.
  • Gaming chairs also called eGaming chairs, are becoming more and more 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 provided 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 by means of elastic loops (eg.
  • Elastic bands firmly attached to the cushion, drawn vertically across the top of the chair's backrest.
  • the upper area of the backrest is typically tapered towards the top in order to function as a headrest.
  • the neck pillow 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 due to the 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.
  • 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.
  • a neck rest that can be fixed on the chair (also subsequently in the sense of a retrofit kit).
  • 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.
  • the document DE 102010020 165 A1 relates to a headrest and seating furniture.
  • the document DE 34 13814 A1 relates to a dental patient chair with a head part fastened to a belt.
  • the document EP 1 716 786 A1 relates to a chair and armchair with an adjustable headrest.
  • a height-adjustable neck support system for an office chair, in particular for a gaming chair, to adapt to different neck support heights of users of different sizes, comprising: a neck support that has a support 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, the first adjusting device being connected to the neck rest and the second adjusting device being connected to the holding plate, and the adjusting devices defining a length of an adjusting range when the adjusting devices are in a state of engagement with one another are engaged; 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 holding 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 area does not change that is covered by the neck support system at maximum deflections of the neck support upwards and downwards with respect to the mounting plate - with the position of the mounting plate unchanged. 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 defined by a maximum, or maximum possible, offset of the adjustment devices in the opposite adjustment directions.
  • this generally means that the longer at least one of the adjustment or latching devices - compared to other adjustment or latching devices - is formed, the larger the adjustment range and the greater the expansion of the adjustment range, in particular the more eccentrically the headrest edge of the neck rest is positioned.
  • 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 cause the neck support to be movable relative to the holding plate only along desired directions.
  • the positive guide elements also have the effect that the neck rest can be attached to the holding plate in a captive manner.
  • 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 the racks and thus enables a gradual adjustment of the neck support relative to the holding plate according to the pitch of the teeth of the rack gene Valleys of the rack engages.
  • the locking lug is pretensioned in the direction of the valleys of the racks.
  • the neck rest has a support body, wherein the support edge extends parallel to a width direction of the neck support and protrudes farthest from the support body in a depth direction, the width direction being oriented horizontally when the system is on Chair is attached.
  • 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 arranged on a side of the neck rest which faces the holding plate in the engaged state, and wherein the supporting edge is arranged on a side of the neck rest which is facing away from the holding plate in the engaged state.
  • Adjusting devices are inaccessible to the user and not visible, so that a The risk of injury is excluded and an aesthetically pleasing overall impression is created when the system is installed.
  • 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 holding 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.
  • the second latching device is arranged on the bottom section of the holding plate.
  • the retaining plate is shell-shaped, so that the edge portion is oriented obliquely, preferably perpendicular, to the bottom portion, and a contour of the bottom portion and / or a contour of the edge portion to a contour of an upholstery space of the chair and / or is adapted to a contour of another chair element.
  • 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.
  • 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 adjust the adjustment devices by a relative movement to disengage the adjustment devices beyond the adjustment range for a change in the orientation of the neck support.
  • the adjustment directions are oriented parallel to a longitudinal extension of at least one of the adjustment devices, a length of at least one of the adjustment devices preferably defining the length of the adjustment range.
  • the above-mentioned object is achieved by a chair with a corresponding neck support system, the contour of the holding plate in particular being adapted to the contour of the chair for the positive, fixed positioning of the system on the chair.

  • the headrest 16 can be switched between the orientations 01 and 02 by removing the headrest 16 from the holding plate 18 and rotating it 180 degrees before the headrest 16 is reinserted into the holding plate 18, for which no active actuation of the securing elements 48 is necessary is because the securing elements 48-2 and 48-3 are beveled accordingly (see. Fig. 7).
  • the orientation 01 is shown on the left in FIG. 8.
  • the orientation 02 is shown on the right in FIG. 8.
  • the locking devices 26-1 and 26-2 (with their respective centers) are each at the level HO.
  • the support edge 22 is arranged lower than in the orientation 02.
  • the various extreme positions P1-P4 of the neck support 16 are illustrated in FIG. 9.
  • the neck rest 16 is in the orientation 01, ie the support edge 22 is arranged in a lower region of the neck rest 16.
  • the neck support 16 is in the orientations 02, ie the support edge 22 is located in an upper region of the neck support 16.
  • the neck support 16 is deflected in the orientation 01 to a maximum in the adjustment direction R2.
  • the position P1 defines the highest position that the support edge 22 can assume in the orientation 01.
  • the latching devices 26-1 and 26-2 are maximally offset from one another (in the direction R2).
  • the position P2 illustrates the lowest point that the support edge 22 can occupy when the neck support 16 is in the orientation 01.
  • the latching device 26-1 of the neck rest 16 is offset at most in the direction R1 with respect to the latching device 26-2.
  • the second latching device 26-2 - via the mounting of the retaining plate 18 on the chair 10 - is positioned in a stationary manner and, in particular, does not change its orientation either.
  • position P3 again illustrates the lowest position of support edge 22 and position P4 the highest position of support edge 22.
  • the highest and lowest positions are indicated in FIG. 9 by Hmaxl, Hmax2, Hminl and Hmin2 .
  • a size of the (entire) adjustment range Vges is independent of the orientation 01 or 02 of the neck support 16.
  • a comparison of the orientations 01 and 02 clearly shows that the neck support 16 is always the same maximum in the directions R1 and R2 is adjustable.
  • 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.
  • 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 26. 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 Latch of the second latching device 26-2 (in the height direction H) minus the length of the second latching device 26-2.
  • the locking devices 26-1 and 26-2 could also be interchanged with regard to their positioning on the neck rest 16 and the holding plate 18. Nevertheless, the length L v of the adjustment range Vges would be determined by the length of the latching devices 26.
  • the eccentric arrangement of the support edge 22 is caused by the cross section of the neck support 16 (in the TH plane).
  • the cross section is an unequal-sided triangle, so that the support edge 22 is eccentric with respect to the locking device 26, which essentially determines or co-determines the length L v of the adjustment range Vges.
  • the positions P2 and P4 are advantageous because the position P2 is suitable for very small users and because the position P4 is suitable for very tall users.
  • Conventional neck pillows would be attached to a different location on the chair 10 to accommodate different body sizes. In the case of the system 10 disclosed here, this is not necessary.
  • the retaining plate 18 remains at the same location, and a coverage area of the system 10 does not change either, despite an extended adjustment range Vges.

Abstract

On divulgue un système (12) réglable en hauteur de support de nuque destiné à une chaise de bureau, en particulier pour une chaise de jeu (10), afin qu'elle s'adapte à différentes hauteurs de support de nuque requises par des utilisateurs de différentes tailles, comprenant : un support de nuque (16), présentant un bord de support (22) ; une plaque de retenue (18), conçue pour se fixer dans une position fixe sur la chaise (10) ; et un mécanisme de réglage (24), comprenant des premier et second dispositifs de réglage (25), dont le premier est relié au support de nuque (16) et le second à la plaque de retenue (18), tandis que les dispositifs de réglage (25) définissent une longueur (LV) d'une zone de réglage (Vges) lorsqu'ils s'engagent l'un avec l'autre en état d'engagement. Les dispositifs de réglage (25) peuvent s'engager l'un avec l'autre de sorte que le support de nuque (16) puisse être relié à la plaque de retenue (18) selon une première orientation (O1) ou une seconde orientation opposée (O2). Ils sont conçus pour être déplacés l'un par rapport à l'autre selon des sens opposés de réglage (R1, R2). Et lorsque le support de nuque (16) est positionné au centre dans la zone de réglage (Vges), le bord de support (22) est disposé excentriquement par rapport à cette dernière. On divulgue en outre une chaise correspondante.
