Description

Technical Field

[0001] The present invention generally relates to cushions for seating furniture and to methods for manufacturing such cushions. Background Art

[0002] Cushions for seating furniture, such as sofa cushions, are typically made of foam. Foam cushions may be a comfortable option in the short term, but they may sometimes look and feel saggy after some use. Another problem with conventional foam cushions is packaging and transportation. Due to the non-flexible composition of conventional foam cushions, they cannot be compressed to a great extent, and conversely, conventional foam cushions have to be transported in large packages, which results in a low efficient use of space in, for example, shipping containers. The production setups for manufacturing foam cushions typically involve cumbersome manual production steps, and the choice of foam materials is often limited to non-sustainable materials.

[0003] Accordingly, there is a need for a cushion for seating furniture that is easier to produce and efficiently transport while also providing good comfort. Summary of the Invention

[0004] It is an object of the present invention to solve or at least mitigate the problems associated with the prior art. This object is achieved by the technology set forth in the appended independent claims; preferred embodiments are defined in the relevant dependent claims.

[0005] In one aspect, there is provided a cushion for seating furniture. The cushion includes a plurality of pocketed springs. A first height of a first set of pocketed springs is different from a second height that is a height of a second set of pocketed springs, such that a top side portion of the cushion is non-planar.

[0006] A pocketed spring may be defined as a spring enclosed in a bag. Due to the independent bag-enclosed springs, the plurality of pocketed springs can become relatively independently flexible, such that each spring can flex individually without affecting adjacent springs. Advantageously, this can increase the comfort of the user, as the weight of the user will be more evenly distributed over the load-receiving surface. The flexibility of the pocketed springs also allows for efficient packaging methods, such as roll packing, so that the cushion requires less space during transportation.

[0007] In an embodiment, the plurality of pocketed springs all have the same diameter. Advantageously, this allows for cost-effective manufacturing.

[0008] The pocket springs can be arranged in rows and columns. This allows for a rectangular shape of the bottom side and linear edges of the pad. Additionally, this configuration allows multiple pocket springs to be manufactured in strings, and then these pocket springs can be handled and connected to each other, rather than assembling individual pocket springs. When all the pocket springs have the same diameter and are manufactured in strings, all these pocket springs can be arranged in rows and columns in a simple handling step even in the same handling machine. This is more efficient than attaching pocket springs in separate handling steps, thus saving time and cost.

[0009] The first height can be higher than the second height, and the first set of pocket springs can be arranged in the center of the pad such that the top side of the pad is convex. Thereby, a higher level of comfort for the user is ensured, and the pocket springs are configured to match the design of a conventional foam material pad.

[0010] The first set of pocket springs can be arranged towards the front edge of the pad such that the top side of the pad is tapered or inclined. In other words, the pad can have a higher height towards the front edge and a lower height towards the rear edge. This facilitates a wider range of design options for the pad and provides the user with a direction not to sit on the front edge of the pad.

[0011] The multiple pocket springs can also include a third set of pocket springs having a third height lower than the first height and the second height. Thereby, a gradually non - flat shape of the top side of the pad can be achieved.

[0012] The third set of pocket springs can be arranged on the opposite side of the second set of pocket springs relative to the first set of pocket springs.

[0013] The multiple pocket springs can be arranged such that there is a gradual increase in the pocket spring height from the edge to the center of the pad.

[0014] The multiple pocket springs can be arranged in a first layer and a second layer. The first layer can be arranged below the second layer. The first layer and the second layer can include pocket springs having different properties such as height, width, and / or hardness. The first layer and the second layer can include pocket springs arranged differently. As an example, the first layer can only include pocket springs having the same height, while the second layer includes pocket springs having different heights. The pocket springs of the first layer and the second layer can be arranged in corresponding rows and columns or overlapping rows and columns. The first layer can be a harder layer, and the second layer can be a softer layer. By arranging the pocket springs in at least two layers, more design options regarding the shape of the pad are facilitated.

[0015] The multiple pocket springs can be arranged such that the bottom side of the pad is flat.

[0016] The pad may further include a top layer disposed on top of the plurality of pocket springs. The top layer may include materials that provide increased stability and / or comfort.

[0017] Alternatively or additionally, the pad may include a cover layer disposed around the plurality of pocket springs. The cover layer may be manufactured and shipped separately from the pocket spring core, which is beneficial as it facilitates cost-effective and convenient packaging, such as coiling the pocket spring core and flat-packing the cover. Assembly of the pad can be simply performed by sewing or buttoning. The pad may alternatively be provided with a zipper, allowing the user to purchase the cover and the pocket spring core separately and easily assemble the pad by zipping the cover around the pocket spring core. This also facilitates more design options for the pad, and the user can easily replace the cover while keeping the pocket spring core. After use, the core and the cover can be easily separated and properly recycled. The cover layer may be combined with the top layer for additional comfort and / or stability, or the cover layer may include additional materials to provide comfort and / or stability by itself.

[0018] The top layer and / or the cover layer may include comfort materials such as foam, padding, fabric, or non-woven textiles. Examples of suitable comfort materials include, but are not limited to: polyester fill, non-woven polypropylene, polyurethane foam.

[0019] In an embodiment, the plurality of pocket springs, the top layer, and / or the cover layer include waterproof materials. The pocket springs may include, for example, stainless steel in a synthetic non-woven material such as polypropylene, and the top layer and / or the cover layer may include polyester fiber fill. The top layer and / or the cover layer may include sufficient waterproof material to provide the necessary comfort and / or stability. This is advantageous as it allows the pad to be manufactured without any water-sensitive materials such as metals that are prone to corrosion, absorbent fabrics, or foams. A pad made only of waterproof materials may be suitable for use, for example, in outdoor seating devices.

[0020] According to a second aspect, there is provided a piece of furniture, particularly a seating furniture such as a sofa or an armchair. The furniture includes a pad according to the first aspect.

[0021] In another aspect, there is provided a method for manufacturing a pad for a seating furniture. The method includes the step of arranging a plurality of pocket springs in rows and columns. A first height of a first group of pocket springs is different from a second height that is the height of a second group of pocket springs, such that the top side portion of the final pad is non-flat. The manufacturing method is highly flexible, and the arrangement of the plurality of pocket springs can be varied in a plurality of ways to achieve different types of pad performance. Thus, pads with different performances can be easily manufactured in small batches, or the properties can even be specifically adapted for each pad. At the same time, the pad can be manufactured in a relatively uncomplicated and cost-effective manner.

[0022] During the arranging step, a plurality of pocketed springs may be arranged such that there is a gradual increase in pocketed spring height from the edge to the center of the cushion.

[0023] During the arranging step, a plurality of pocketed springs may be arranged in a first layer and a second layer.

[0024] The method may further include the step of roll-packing the cushion. Roll-packing is an efficient way to compress the cushion for transportation and greatly improves the cost-effectiveness of the logistics involved in the manufacture and distribution of the cushion.

[0025] Other objects and advantages of the present invention will be readily apparent to those skilled in the art upon reading the following detailed description of the different embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Hereinafter, a cushion for seating furniture and a method for manufacturing a cushion for seating furniture will be described.

[0037] The terms "top" and "bottom" are used to define the normal position of the cushion, i.e., the top side on which a person using the cushion intends to sit, and the bottom side that forms the lower side of the cushion during normal use. Similarly, the term "front" refers to the front edge of the cushion that points outward from the seating furniture, while the "rear" refers to the rear end of the cushion that points inward towards the back of the seating furniture.

[0038] As used in this specification, the expression "longitudinal" refers to the length direction of the cushion, i.e., the front-to-back direction. The expression "transverse" refers to the width direction of the cushion. Thus, the longitudinal direction and the transverse direction are perpendicular to each other.

[0039] The cushion is exemplified in the following specification as a seat cushion. However, the benefits described below also apply to other types of cushions for seating furniture, such as, for example, back cushions.

[0040] From Figure 1a the beginning, there is shown a seating furniture 1 in the form of a sofa here. The sofa 1 includes a backrest, a seat, legs, and armrests. The sofa 1 also includes a sofa cushion 100 in the form of a seat cushion on top of the seat and a back cushion that leans against the backrest.

[0041] In Figure 1b there is further shown the sofa cushion 100, which illustrates the non-planar (or non-flat) configuration of the top side T.

[0042] Figure 2 Other details of the cushion 100 according to an embodiment are shown. The cushion 100 includes a plurality of pocket springs 10. A first height H1 of a first group of pocket springs S1 is different from a second height H2 that is the height of a second group of pocket springs S2, such that the top side T of the cushion 100 is non-flat.

[0043] Each pocket spring 10 includes a spring and a fabric material that encloses the spring, preferably on all sides of the spring. The fabric material can be, for example, a non-woven fabric material, a material including a thermoplastic material, or another suitable material. The spring is preferably a helical spring, but other spring types can also be considered. Although shown as a cylindrical shape, the pocket spring 10 can have other configurations such as a barrel shape, an hourglass shape, etc.

[0044] The pocket springs 10 are arranged side by side in rows and columns. The rows extend in the transverse direction, and the columns extend in the longitudinal direction. As Figure 2As shown, the pocket springs 10 are aligned both in the lateral direction and in the longitudinal direction. The pocket springs 10 thus form a rectangular shape, thereby allowing for linear edges of the pad 100. The pocket springs may alternatively be arranged to be offset towards each other in the lateral direction and / or in the longitudinal direction. In some embodiments, the outer rows and / or outer columns may be made shorter, for example by omitting one or more pocket springs 10, such that the pad 100 presents rounded corners.

[0045] As shown in FIGS. 1 and Figure 2 As shown, a first set of pocket springs S1 is arranged in the center of the pad 100 and has a height H1 that is higher than the height H2 of a second set of pocket springs S2, which are arranged laterally and longitudinally outside the first set S1. Thereby, the top side portion T of the pad 100 assumes a convex shape. The convex shape of the pad is desired for many reasons, for example to increase the comfort of the user. Conventionally, pads for seating furniture have typically been made of foam material in order to facilitate such a shape. As mentioned in the background section of the specification, foam materials have many drawbacks. For example, the material often needs to be selected from unsustainable materials that have a low quality over time. The shape formed by the foam material may deform over time. In other words, a foam pad for seating furniture such as a sofa may look and feel saggy after being used for some time. Another problem with conventional foam-based pads is packaging and transportation. Due to the non-flexible composition of conventional foam-based pads, they cannot be compressed very much, and conversely, conventional foam-based pads have to be transported in large packages, which results in a lower efficient use of space in, for example, a shipping container. The production setups for manufacturing foam pads typically involve cumbersome manual production steps, and the selection of foam materials is often limited to unsustainable materials. By the pad 100 of the inventive concept including pocket springs of different heights, the need for foam material is reduced. The solution presented herein provides a manufacturing process with lower labor intensity, since the solution enables lean and automated production. Another effect of the pad 100 as disclosed herein is that the pad 100 can be packaged by vacuum extrusion and curling to save space and be easy to transport. Additionally, by having a shape achieved by pocket springs 10 of different heights, a better and more durable quality of the pad 100 is ensured.

[0046] Although not shown, the first set of pocket springs S1 may be arranged towards the front edge of the pad 100 such that the top side portion T of the pad 100 is tapered. This is advantageous for the same reasons as those listed above.

[0047] Returning to Figure 2 and Figures 3a to 3b, the third set of pocketed springs S3 has a third height lower than the first height and the second height. The third set of pocketed springs S3 is arranged on the opposite side of the second set of pocketed springs S2 with respect to the first set of pocketed springs S1. Thereby, the convex and / or tapered shape can be enhanced, and more design options are facilitated. A plurality of pocketed springs 10 are arranged such that there is a gradual increase in the height of the pocketed springs from the front end portion to the center of the pad 100.

[0048] In Figure 2 , a plurality of pocketed springs 10 are arranged in the first layer L1 and the second layer L2. It should be appreciated that a single layer of pocketed springs or a combination of several layers of pocketed springs is also feasible for forming the pad 100. By arranging the pocketed springs 10 in at least two layers L1, L2, more design options for the pad 100 can be obtained because more combinations of pocketed springs 10 with different heights and especially different stiffnesses are possible. The first layer L1 may include, for example, pocketed springs 10 of a single height and increased stiffness, providing a firm base for the pad 100, and the second layer L2 may include pocketed springs 10 of different heights and reduced stiffness, providing comfort for the user of the pad 100.

[0049] Thereby, the softness of the pad 100 can be easily adjusted during the manufacturing process because the elasticity of the springs can vary for the entire pad 100 or for parts of the pad 100. For example, stiffer springs can be arranged in the first layer L1 and / or towards the edges of the pad 100, and less stiff springs can be arranged in the second layer L2 and / or in the center of the pad 100. Different stiffnesses in different regions of the pad can also be achieved by the diameter of the spring pockets towards the edges being smaller or larger than the diameter of the spring pockets towards the center of the pad 100. In some embodiments, a plurality of spring pockets may have the same diameter.

[0050] In some examples, a plurality of pocketed springs 10 are arranged in rows and columns such that the pad 100 includes central pocketed springs surrounded by edge pocketed springs. The edge pocketed springs are preferably arranged in one row / column, two rows / columns or three rows / columns along each side of the pad 100, which means that each edge is formed by one, two or three pocketed springs in width. However, in some examples, the edge pocketed springs are arranged only at one or more sides of the pad.

[0051] The central pocketed springs are arranged immediately inside the edge pocketed springs. The central pocketed springs may form a uniform body of central springs covering the entire space inside the edge pocketed springs, or additional pocketed springs may be arranged inside or adjacent to the central pocketed springs. Thus, in addition to the edge pocketed springs, the central pocketed springs are not necessarily the only pocketed springs of the pad. For example, the central pocketed springs may be one or more pocketed springs arranged inside the edge pocketed springs.

[0052] Preferably, in some examples, the edge pocketed springs and the central pocketed springs have the same diameter.

[0053] A plurality of pocketed springs 10 may be arranged such that the bottom side portion of the pad 100 is flat.

[0054] As Figure 2 and Figures 3a to 3b illustrated, the pad 100 also has a top layer L3, which is arranged on top of the pocketed springs 10. The top layer L3 further stabilizes the shape of the pad 100 while providing additional comfort to the user. Many different materials and sizes can be considered for the top layer L3, such as fabrics, foams, non-woven textiles or plastic materials. The thickness of the top layer L3 can be in the range of 1 cm to 25 cm, for example in the range of 3 cm to 10 cm. Figure 2 and Figures 3a to 3b The pad 100 also includes a front panel F and a bottom layer B. The front panel F may include foam, such as polyurethane foam and / or stuffing, such as natural polyester fiber. The front panel F may include any other suitable materials for padding, filling or decorative purposes. The bottom layer B can further stabilize the shape of the pad 100 and can include fabric and / or polymer materials. The bottom layer B may be provided with an anti-slip material to better position it in the sofa 1.

[0055] Figure 3a illustrates a pad 100 according to an embodiment. The pad 100 has a top profile similar to the profile of the top side portion T shown in Figure 2 . However, in Figure 3a , the pad 100 has a single layer L1 of spring bags 10. As can be seen in Figure 3a , the pad 100 has an upper profile corresponding to the different heights of the pocketed springs S1, S2, S3. Another example of the pad 100 is shown in Figure 3b . The pad 100 has a tapered top side portion T because the pocketed springs 10 with higher heights are arranged towards the front edge and the pocketed springs 10 with lower heights are arranged towards the rear edge. In Figure 3b , the pad 100 is provided with two layers L1, L2 of pocketed springs 10. Although not illustrated, more groups of pocketed springs 10 or individual pocketed springs 10 with different heights are feasible. Each pocketed spring 10 can even have a unique height to allow for a more continuous variation. The height of the front panel F can be similar to the height of one or two pocketed springs 10, or the height of the front panel F can be higher / lower to provide more design options. Each row and each column can be fitted with between 5 and 20 pocketed springs 10, preferably about 10 to 12 pocketed springs (as Figure 2 , Figures 3a to 3bas shown in). However, fewer or more pocket springs 10 can be used to reduce or increase the width of the pad 100 in the lateral direction and / or the longitudinal direction.

[0056] Figure 4 FIG. schematically shows a method for manufacturing a pad 100. The method includes the step of arranging a plurality of pocket springs 10 in rows and columns M1. The first height H1 of the first set of pocket springs S1 is different from the second height H2 which is the height of the second set of pocket springs S2, such that the top side T of the final pad 100 is non-flat. The pocket springs 10 can be manufactured as follows. Each spring is made of metal wire. Each spring is positioned in a spring bag made of a fabric material, after which the spring bag is sealed, for example, by welding.

[0057] The pocket springs 10 can be arranged in a plurality of parallel spring strings. The spring strings can extend laterally or longitudinally. The spring strings can be attached to each other side by side, for example, by an adhesive. Compared with the conventional production setup for manufacturing foam pads, Figure 4 the method illustrated in FIG. provides a manufacturing process with lower labor intensity, because the method is lean and automated production. If the pad 100 includes a double layer L1, L2 of pocket springs, the manufacturing of the pocket springs for the first layer L1 and the second layer L2 can be carried out simultaneously. Regarding Figure 2 and Figures 3a to 3b the described embodiments can be manufactured by this method. For example, during the arranging step M1, a plurality of pocket springs can be arranged such that there is a gradual increase in the height of the pocket springs from the front end of the pad 100 to the center. As Figure 4 shown in FIG., the method can also include an additional step of roll wrapping M2. In this step M2, the pad 100 is vacuum-packed, rolled up and wrapped such that a very compact and space-reducing package is obtained. Once the package is opened, the pad 100 will return to its desired shape.

[0058] Now turning to Figures 5a to 5g , different embodiments of the pad 100 for seating furniture will be briefly described. In Figure 5a FIG., a rectangular pad 100 is shown, in which the central part 101 of the top side T is raised relative to all four edges. The central part 101 tapers towards all four edges, which means that the spring bags (not shown) are constructed and distributed accordingly, i.e., tall spring bags are arranged at the central part 101, short spring bags are arranged at the edges, and intermediate spring bags (of intermediate height) are arranged between the short and tall spring bags.

[0059] In Figure 5b FIG., a similar pad 100 is shown, but here the overall height is increased compared to the pad in Figure 5a . Optionally, in Figure 5bIn [description], the front edge of the cushion 100 can be made of a spring pocket with higher robustness, thereby providing additional stability to the front edge and reducing the risk of the user falling off the cushion 100.

[0060] In Figure 5c Another embodiment of the cushion 100 is shown. The cushion 100 is elongated compared to the Figure 5a cushion and can thus be used for a sofa bed or a multi-seat sofa with a single cushion.

[0061] In Figure 5d Another embodiment of the cushion 100 is shown. The cushion 100 is non-flat in a similar manner as shown in Figure 5a but, compared to the Figure 5a cushion, the current Figure 5d cushion 100 is tapered in the front-to-back direction. Thus, the cushion 100 is wider at its front end than at its rear end. This is achieved by reducing the number of spring pockets in the width direction when moving from the front end towards the rear end.

[0062] In Figure 5e a cushion 100 with a significantly reduced overall height is shown. Thus, compared to the Figure 5a cushion, the current Figure 5e cushion 100 is made of significantly shorter pocket springs, but the top side T is still non-flat by increasing the height of the pocket springs towards the central position 101. In a preferred embodiment, the outermost pocket springs in each row / column are shorter than the inner central pocket springs. Thus, Figure 5e the non-flat cushion 100 shown in

[0063] Figure 5f is formed of pocket springs with varying heights in order to achieve a non-flat top side T despite its small height.

[0064] In Figure 5g yet another embodiment of the cushion 100 is shown, the cushion 100 having a "T" shape such that the cushion 100 is suitable for an armchair or other similar seating furniture. The front edge has an increased width compared to the central part and the rear edge. Optionally, the width, especially with respect to the central part and the rear edge, can be reduced in the front-to-back direction. As Figure 5g indicated in

[0065] For Figures 5a to 5gIn the embodiment shown, although a foam layer may be disposed on top of the spring pocket to soften the top side T to increase user comfort, it should be noted that due to the different heights of the pocketed springs, an uneven top side T of the pad 100 is provided.

[0066] Turning now to Figures 6a to 6g , different spring pocket configurations for different embodiments of the pad 100 are shown. Throughout the description of these figures, the reference numeral FE corresponds to the front edge, RE corresponds to the rear edge, LS corresponds to the left side, and RS corresponds to the right side. Starting from Figure 6a , a spring pocket configuration of the pad 100 corresponding to Figure 5a is shown. The spring pockets are arranged in rows and columns, where each tapered edge is formed by two rows / two columns of spring pockets with gradually decreasing heights. The front edge is supported by the front panel F as described above, and a top layer L3 may be provided to enhance comfort.

[0067] In Figure 6b , another configuration indicating a rectangular pad is shown. The spring pockets are taller, thus corresponding to the pad shown in Figure 5b . Here, a top layer L3 and a rectangular frame 102 covering all sides of the pad are provided. In addition, the outermost spring pockets form a single spring pocket with a tapered width.

[0068] In Figure 6c , another configuration of the pocketed springs indicating the pad for forming Figure 5c is shown. In the example shown, a front panel F is provided, but the spring pockets are much shorter than those shown in Figure 6a .

[0069] Figure 6d The spring pocket configuration shown corresponds to the pad 100 shown in Figure 5d . The first layer of spring pockets forms a tapered shape by having one less spring pocket at the rear edge than at the front edge. All the spring pockets in the first layer have the same height. The central portion 101 is formed by so-called micro spring pockets disposed at the central portion of the first layer. The micro spring pockets have a smaller diameter and height, thereby forming a raised area at the top side T.

[0070] In Figure 6e , another spring pocket configuration corresponding to the pad shown in Figure 5e is shown. Short spring pockets are used, and a material (such as foam) may surround the spring pockets on all sides (except the bottom side) to form a desired shape. One or more of the outermost pocketed springs in each row and column may be shorter than the inner central pocketed springs, such that the top side T of the final pad 100 obtains a convex shape.

[0071] InFigure 6f is shown a spring pocket configuration for forming a pad 100 as shown in Figure 5f . The height of the spring pocket decreases in the front-to-back direction and in the side-to-center direction. A front panel F is provided at the front edge and a top layer 101 is disposed on the spring pocket.

[0072] In Figure 6g is shown a spring pocket configuration for forming a Figure 5g T-shaped pad 100 as shown in. The front portion of the spring pocket configuration includes two rows of a certain number of spring pockets, and a tapered rectangular portion is formed adjacent to the front portion. The front row of the rectangular portion is disposed at the center of the front portion, whereby the rectangular portion is tapered in the backward direction such that the rear edge RE is formed by a row of spring pockets having one less spring pocket in total number than the front row of the rectangular portion. A front panel F and a top layer T are provided.

[0073] Figure 7 Illustrated is a pad including a cover layer L4 enclosing a bagged spring 10. The cover layer L4 can be manufactured and transported separately and then zipped, buttoned or sewn around the bagged spring core 10. The cover layer L4 can be thicker on one or more sides to provide additional padding. The pad can also include a top layer L3 between the bagged spring core 10 and the cover layer L4.

[0074] It should be noted that the inventive concept is in no way limited to the embodiments described herein and that several modifications are possible without departing from the scope of the appended claims. In the claims, the term "comprising / including" does not exclude the presence of other elements or steps. Additionally, although the individual features may be included in different claims, these features can be advantageously combined and including the features in different claims does not mean that the combination of the features is not feasible and / or advantageous. Furthermore, a singular reference does not exclude a plural. The terms "a", "one", "first", "second", etc. do not exclude a plurality. The reference numerals in the claims are provided only as illustrative examples and should not be construed as limiting the scope of the claims in any way.
