[0018] In the drawings, reference numeral 10 generally designates a support unit 10 (Figures 1 and 2) for use on an article of furniture, such as a sofa 12 (Figures 3-5). The support unit 10 includes an adjustable support structure 14 and a cushion member 34 carried by the support structure 14, The support structure 14 is in the form of a frame 16 with a support element 18 displaceably arranged relative to the frame 16. In this embodiment, the support element 18 is pivotally coupled to the frame 16 at pivot points 20, 22. However, it will be appreciated that the support structure 14 may be adjustable via any other suitable means, for example, a telescopic arrangement and / or a modular arrangement.

[0019] The frame 16 comprises two laterally spaced legs 30, 32 which are curved for following a periphery or contour of a part of the sofa 12 as described in more detail below. The laterally spaced legs 30, 32, in combination with the support element 18, allows the support structure 14 to be mounted to, or removed from, the sofa 12. Specifically, at least a part 19, 21 of the support structure 14 is removably receivable between the seat cushion 24 and the back rest 26 of the sofa 12 to mount the support structure 14 to the sofa 12. In this way, the support structure 14 is displaceably mountable to the article of furniture 12. It will be appreciated that the support structure 14 may be of any suitable shape and comprise any suitable elements for displaceably mounting the support structure 14 to the sofa 12. It will also be appreciated that the legs 30, 32 may instead be formed in one or more rectilinear portions to follow a rectilinear periphery of part of an article of furniture.

[0020] In this embodiment, the sofa 12 includes legs 23 and a base 25 supporting a plurality of seat cushions 24. A back rest 26 extends operatively upwardly from the base 25. The back rest 26 supports a plurality of back cushions 28, there being the same number of back cushions 28 as there are seat cushions 24. It will be appreciated that, while the illustrated embodiment shows a three seater sofa, the appropriate number of support units 10 could equally applicably be used with a 2 seater sofa, a chair, a chaise, or the like

[0021] While the illustrated embodiment shows one support unit 10 per seat cushion 24, the support unit 10 is modular in nature and can be placed anywhere relative to the back rest 26. Thus, if the sofa comprised one continuous seat portion, one or more support units 10 may be provided to be placed at any desired location along the back rest 26 of the sofa 12. The one or more support units 10 may each have a back cushion 28 associated with them.

[0022] As best shown in Figures 3 and 5, the support structure 14 is configured to be arranged in a first orientation 36 relative to the sofa 12 for enabling the cushion member 34 to adopt a first position 38 relative to the sofa 12. In this first position 38, the cushion member 34 functions as a bolster. To allow the support structure 14 to be arranged in the first orientation 36, the support element 18 is arranged in a first configuration 40 in which the support element 18 is pivoted to be located between within the frame 16 between the legs 30, 32 of the frame 16. The cushion member 34, functioning as a bolster, provides support to its associated back cushion 28 of the sofa 12.

[0023] As indicated above, to assist with arranging the support structure 14 in the first orientation 36, at least a part 42 of the support structure 14 is configured to follow a periphery, contour, 44 (Figure 5) of the back rest 26 of the sofa 12. This arrangement, along with at least the part 19 being received between the seat cushion 24 and the back rest 26 of the sofa 12, provides a suitable surface area for a frictional engagement between the support structure 14 and the sofa 12. Further, as best shown in Figure 5, when the cushion member 34 functions as a bolster, the cushion member 34 bears against an operatively top portion 39 of the back rest 26 of the sofa 12. This assists in locating the cushion member 34 in its first position 38 relative to the sofa 12.

[0024] As best shown in Figure 4, the support structure 14 is also configured to be arranged in a second orientation 46 relative to the sofa 12 for enabling the cushion member 34 to adopt a second position 48 relative to the sofa 12. In this second position 48, the cushion member 34 functions as a head rest. To allow the support structure 14 to be arranged in the second orientation 46, the support element 18 is arranged in a second configuration 50 in which the support element 18 is pivoted from its first configuration 40 to extend operatively downwardly from the pivot points 20, 22 of the frame 16.

[0025] Once again, as indicated above, to assist with arranging the support structure 14 in the second orientation 46, at least a part 52 of the support structure 14 is configured to follow a periphery, or contour, 54 (Figure 4) of the back cushion 28 of the sofa 12. This arrangement, along with at least the part 21 being receivable between the seat cushion 24 and the back rest 26 of the sofa 12, provides a suitable surface area for a frictional engagement between the support structure 14 and the sofa 12. Further, when the support structure 14 is in the second orientation 46, at least a part of the legs 30, 32 of the frame 16 of the support structure 14 of the unit 10, impart a measure of support to the back cushion 28 to inhibit folding of the back cushion 28 over the top of the back rest 26 of the sofa 12.

[0026] As shown in Figure 4, when the cushion member 34 functions as a head rest, the cushion member 34 bears against an operatively top portion 56 of the back cushion 28 of the sofa 12. This assists in locating the cushion member 34 in the second position 48. It will be appreciated that, in some embodiments, at least a part of the support element 18, when in its second configuration 50, is shaped to follow the periphery 44 of the back rest 26 of the sofa 12. This increases the surface area for frictional engagement between the support structure 14 and the sofa 12 in the second orientation 46.

[0027] Thus, in use, the support structure 14 of the support unit 10 may initially be arranged in the first orientation 36 as shown in Figures 1 and 6A. With reference to Figure 3, the user may mount the support structure 14, in its first orientation 36, to the sofa 12 by inserting at least the part 19 of the support structure 14 between the seat cushion 24 and the back rest 26, such that the cushion member 34 bears against the operatively top portion 39 of the back rest 26 of the sofa 12. This locates the cushion member 34 in the first position 38. The back cushion 28 may then be applied to the sofa 12 such that it bears against the cushion member 34 in the first position 38 for the cushion member 34 to act as a bolster for the back cushion 28. In this way, a user resting against the back cushion 28 will be supported, since folding or crimping of the back cushion 28 due to the applied weight of the user will be reduced by the cushion member 34 acting as a bolster.

[0028] Should the user wish to use the support unit 10 as a head rest, the user first lifts the support structure 14 out from between the seat cushion 24 and the back rest 26 of the sofa 12. The user then follows the steps shown schematically in Figures 6A-6D. Starting with the support element 18 in its first configuration 40, as shown in Figure 6A, the user pivots the support element 18 in the direction of curved arrow 58 as shown in Figure 6B, such that the support element 18 moves to its second configuration 50 as shown in Figure 6C. Once the support element 18 has been moved to its second configuration 50, the user rotates the support unit 10 about a longitudinally extending, bisecting axis (not shown) in the direction of curved arrow 60 as shown in Figure 6C to adopt the position shown in Figure 6D, such that the support structure 14 is in position to be arranged in the second orientation 46 (Figure 4).

[0029] With reference to Figure 4, the user mounts the support structure 14 in the second orientation 46 to the sofa 12 by inserting at least the part 21 of the support structure 14 between the seat cushion 24 and the back rest 26. In this second orientation 46, the cushion member 34 bears against the operatively top portion 39 of the back cushion 28 of the sofa 12 to function as the head rest.

[0030] If the user wishes to use the support unit 10 as a bolster once again, they would follow the steps of the method of use in reverse, that is, starting from Figure 6D and following the curved arrows 58, 60 in reverse to convert the support unit 10 to the configuration as shown in Figure 6A, ready to be arranged in the first orientation 36.

[0031] Advantageously, the support unit 10 acts as an accessory to the sofa 12 with two functions in a single article; the first function being to act as a bolster for the back cushion 28 of the sofa 12, and the second function being to act as a head rest for the user. In addition, the displaceability of the support unit 10 allows the user the choice of whether to apply the support unit 10 as a head rest or bolster, or whether to store the support unit 10 for a less cluttered aesthetic for the sofa 12. In some embodiments, the support element 18 being pivotally connected to the frame 16, allows the user to store the support unit 10 in the more compact first orientation 36 by moving the support element 18 to its first configuration 40.

[0032] It will be appreciated by persons skilled in the art that the support structure 14 may be formed in any suitable manner, such as the use of a solid panel instead of the frame 16 with legs 30, 32. Further, the support element 18 may also embody any suitable form, such as a solid panel displaceably arranged relative to the frame 16 or relative to the said solid panel embodiment of the frame 16. Further, it will be appreciated that a part the support structure 14 may be attached to the sofa 12, and it will also be appreciated that the support unit 10 may be applicable to other articles of furniture, such as an armchair, a bed frame, an office chair, or the like.

[0033] It will be appreciated by persons skilled in the art that numerous variations and / or modifications may be made to the above-described embodiments, without departing from the broad general scope of the present disclosure. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
