Definitions

  • the present disclosure relates to an adapter for attaching an accessory to a chair, in particular to a gaming chair that has a seat and a backrest, and a chair with such an adapter.
  • 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.
  • 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 classic desk chairs, which is due to the special cushions (source: www.stern.de).
  • the (separate) neck pillow is usually attached by means of elastic loops (e.g.
  • 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. Furthermore, light sources integrated in the chair, which are not uncommon in gaming chairs, can be covered by the neck cushion.
  • the document DE 202008000077 U1 relates to seating and / or reclining furniture.
  • the document DE 202005000 852 U1 relates to seating and reclining furniture with back cushions, armrests and shelves that can be inserted all around and also with variable seat depth.
  • the document EP 1 716 786 A1 relates to a chair and an armchair with an adjustable headrest. It is therefore desirable to provide an adapter which can be fixed to the chair (also subsequently in the sense of a retrofit kit) and which enables an accessory to be attached. In particular, an attachment of the accessory is desired that is optically inconspicuous so that the accessory cannot be recognized as an accessory.
  • an adapter for attaching an accessory to a chair, in particular to a gaming chair, which has a seat and a backrest, the seat and / or the backrest each consisting of several parts, in particular special upholstery elements, are formed, which are separated from one another by at least one intermediate space that extends in a depth direction of the seat and / or the backrest and along a respective associated dividing line, wherein the adapter has: an insert member which has at least one insert portion that positively can be inserted into the at least one intermediate space, the at least one insertion section extending along a contour which is defined by the respective associated dividing line between directly adjacent parts of the seat and / or the backrest; and a fastening member which is connected to the male member and which is configured to fix the accessory to the fastening member.
  • the adapter is inserted into the chair.
  • the connecting elements are not visible.
  • the form fit ensures a high level of positional security, even if the user moves heavily.
  • the forces exerted by the user during a movement cause the adapter to be moved even deeper into the gaps.
  • the adapter cannot be lost. From the outside it is not noticeable that the adapter does not originally belong to the chair. There are no visually disturbing accessories (e.g. rubber bands).
  • the male member in an inserted state, can preferably be fixed in a non-positively releasable manner by a spring force in the at least one intermediate space in the chair.
  • the adapter remains in its desired mounting position even when forces act on the adapter which are directed opposite to an insertion force.
  • the male member is completely received by the at least one intermediate space, so that it is not visible from the outside.
  • At least some of the parts, preferably all parts, of the chair are upholstered so that the at least one intermediate space is a cushion space.
  • the upholstery ensures a holding force which is caused by the elasticity of the upholstery.
  • the upholstery ensures that the adapter is automatically fixed in place in the chair.
  • the at least one insertion section can extend continuously or discretely distributed along the respective associated dividing line.
  • the fastening member has a plate which is shaped so that the plate is in flat contact with the opposite parts of the seat and / or the backrest in the inserted state of the adapter.
  • the adaptation of the shape of the adapter to the shape of the chair parts into which the adapter is inserted produces a good optical effect.
  • the adapter visually merges with the chair.
  • the adapter is not perceived as an accessory, which in particular improves customer acceptance.
  • the plug-in member has a thickening along a depth direction of the intermediate space in order, for example, to engage behind a zip fastener, which is provided in the at least one intermediate space through the, preferably padded, parts.
  • the thickening ensures anchoring of the adapter in an undercut provided on the chair side. The adapter cannot be accidentally disconnected from the chair.
  • the plug-in member can comprise one or more centering lugs, which are arranged discretely distributed along the contour.
  • the centering lugs facilitate an initial positioning of the adapter on the chair before the adapter is pressed into the gaps.
  • the fastening member can comprise an adjusting device which can be brought into engagement with a further adjusting device which is fastened to the accessory part in order to adjustably fasten the accessory part to the chair.
  • a chair which comprises the adapter and an accessory.

  • the height-adjustable neck support system 12 generally has a neck support 16 and a holding plate 18.
  • the system 12 can also have a (fabric) cover 20, which can be pulled over the neck support 16 for reasons of hygiene, see FIGS Height adjustability is irrelevant.

  • the neck support 16 is wedge-shaped and has a support body (cushion, e.g. made of foam) and a base plate (optionally provided separately for this), see FIG. 7.
  • the neck rest 16 generally defines a support edge 22 (see. Dashed line in Fig. 3), on which a (not shown here) user can support himself with his neck while using the chair 10, that is, while sitting Place the head in an area above the supporting edge 22.
  • the wedge shape of the neck rest 16 is along the width Direction B is preferably concave in order to accommodate the neck as ergonomically as possible (ie in particular in a form-fitting manner).
  • the neck support 16 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 an unequal triangle, as will be explained in more detail below with reference to FIGS.
  • the system 12 comprises an adjustment mechanism 24, which has at least two adjustment devices 25, which are designed in particular as latching devices 26.
  • the adjustment mechanism 24 can, for example, be equipped with a locking (stepwise), stepless (not shown) or also via a gear (not shown) with a handwheel.
  • the adjustment devices 25 could, for example, also be designed as a slot and slot nut connection, as a magnetic strip and magnet block connection or as a similar connection made of mutually corresponding elements.
  • a step-by-step locking mechanism is assumed as an example.
  • the adjusting 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 connected to the neck support 16 (see FIG. 4) and wherein the second latching device 26-2 is formed, for example, in the form of a point and is connected to the holding plate 18 (cf. FIG. 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 holding plate 18 can be permanently and detachably in a first orientation 01 and in a second, opposite orientation 02 (cf. 8) is connectable.
  • the adjustment devices 25 and in particular the locking devices 26 are set up in opposite adjustment directions R1 and R2 (see. Fig. 7-9), which are parallel to a longitudinal extension of at least one of the locking devices 26, here the locking device 26-1, are oriented to be moved relative to one another, preferably in steps, within an adjustment range Vges (cf. FIG. 9).
  • the neck support 16 is therefore rotated by 180 °, as illustrated in FIG. 4 by an arrow, in order to move from the first orientation 01 (cf. FIG. 8, left) to the second Orientation 02 (see. Fig. 8, right) to change.
  • the locking devices 26-1 and 26-2 are disengaged by shifting against each other, as will be explained in more detail below, in order to be able to rotate the neck support 16 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.
  • the rotation by 180 ° can also be implemented differently.
  • the neck support 16 could, for example, also be permanently (and captively) connected to the holding plate 18 via a swivel joint (not shown). In this case, the neck support 16 can be rotated through 180 ° without separating the neck support 16 from the holding plate 18. The user pulls, for example, on the neck support 16, disengages the adjustment devices 25 (not shown) in this way, while the neck support 16 remains permanently connected to the holding plate 18, rotates the support 16 and then pushes it again in the opposite direction into the holding plate 18 in order to bring the adjustment devices 25 into engagement again.

In the area of the thickening 114, the insertion section 110 has a greater material thickness than in a region facing the fastening member 108. In this way, the adapter 100 is protected from unintentional loosening (in the depth direction T of the intermediate space 104) from the chair 10.
  • the insert member 106 can have one or more centering lugs 116, as is shown schematically by way of example in the side view of FIG. 13 shows part of an insertion section 110 which, as in the other embodiments, extends in a collar-shaped manner, preferably vertically, from the bottom-like fastening member 108, in FIG. 13 upwards.
