Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority to, and the benefit of, Singapore Patent Application No. 10202107385U, filed on Jul. 5, 2021.

FIELD OF INVENTION

The present invention relates broadly, but not exclusively, to a head support assembly and method of supporting a cushion on a headrest.

BACKGROUND

A typical seat head cushion or pillow is attached to a chair using an integrated elastic strap or Velcro strap and a user subsequently adjusts the head cushion/pillow to their desired position. However, the elastic strap may re-position the cushion/pillow to an unstretched position due to the nature of the strap's elasticity even after adjustment. Furthermore, the strap loses its elasticity after prolonged stretching and relaxing cycles, and thus the cushion/pillow may be loosely attached to the chair.

Current elastic straps also restrict the adjustability of the cushion/pillow. In addition, the use of elastic or Velcro straps may not look good aesthetically as the elasticity of the straps is lost after using for a period of time.

Accordingly, a need exists to provide a head support assembly that seeks to address some of the above problems.

DETAILED DESCRIPTION

The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description. Herein, a head support assembly is presented in accordance with present embodiments which may have the advantages of having a clean and neat cushion/pillow that can be securely attached to a chair while being able to be easily adjusted at the same time.

FIG. 1A shows a side view of a head support assembly 100, according to an example embodiment. In FIG. 1A, embedded or occluded elements are shown in broken lines. The head support assembly 100 includes a headrest 102 extending upwardly from a seatback 104, the headrest 102 comprising one or more magnetizable plate members 106. The head support assembly 100 also includes a cushion 108 adjustable between a first position and a second position relative to the headrest 102 (shown in FIGS. 1B and 1C). The cushion 108 includes a plurality of magnets 110a, 110b such that the one or more magnetizable plate members 106 and the plurality of magnets 110a, 110b are configured to magnetically attach the cushion 108 to the headrest 102 for supporting the cushion 108 at the first or second position. In other words, the magnetic force between the magnets 110a, 110b and the plate members 106 can support the weight of the cushion 108 at the first or second position.

The cushion 108 includes a deformable fore section 112 and a substantially flat aft section 114, whereby the fore section 112 is configured to support a head of a user (not shown) and the aft section 114 is configured to slidingly abut a substantially flat fore surface 116 of the headrest 102. The one or more magnetizable plate members 106 are embedded adjacent the fore surface 116 of the headrest 102. Each of the plurality of magnets 110a, 110b includes a base 118a, 118b and a protrusion 120a, 120b extending from the base 118a, 118b, whereby the protrusion 120a, 120b has a cross-section smaller than a cross-section of the base 118a, 118b. A more detailed view of the base 118a, 118b and the protrusion 120a, 120b is shown in FIG. 2A. Even though two magnets 110a, 110b are shown in this Figure, it can be appreciated that more than two magnets are possible, for example, four magnets as shown in FIG. 2A, to better attach and support the cushion 108 to the headrest 102. The strength and/or positions of the magnets 110a, 110b may be selected based on practical requirements, e.g. number of magnets used, weight of the cushion 108, etc.

In example embodiments, the magnets 110a, 110b magnetically attach the cushion 108 to the headrest 102 by having the magnet protrusions 120a, 120b adjacent to the one or more magnetizable plate members 106. The magnetic force of the magnets 110a, 110b can be sufficiently strong to ensure that the cushion 108 is attached to the headrest 102 without having any physical and mechanical interaction. At the same time, the plurality of magnets 110a, 110b are securely held in place by the cushion 108 and are not dislodged when the cushion 108 is magnetically attracted to the one or more magnetizable plate members 106.

FIGS. 1B to 1C show perspective front views of the head support assembly 100 of FIG. 1A with the cushion 108 at a first and second position, respectively, relative to the headrest 102, according to an example embodiment. In FIG. 1B, the cushion 108 is magnetically attached to the headrest 102 at a first position. If a user finds that the cushion 108 is too low, he may adjust the cushion 108 to a second position above the first position as shown in FIG. 1C. As the cushion 108 is magnetically attached to the headrest 102 without the use of physical or mechanical means, the cushion 108 can be easily adjusted by the user between the first position and the second position. It can be appreciated that the user can adjust the cushion 108 to various positions along the one or more magnetizable plate members 106 and not limited to only the first and second positions. The plurality of magnets 110a, 110b can be selected to include dimensions, magnetic strength and maximum temperature characteristics based on the weight of the cushion 108. This may ensure sufficient magnetic force to support the cushion 108 at the first or second position.

FIG. 2A shows an exploded perspective view of the cushion 108 of the head support assembly 100 of FIG. 1A, according to an example embodiment. As shown in FIG. 2A, the cushion 108 includes a carrier member 202 removably attached to the aft section 114, the carrier member 202 configured to securely retain the plurality of magnets 110a, 110b, 110c, 110d such that the magnets are disposed at the aft section 114 proximate to the one or more magnetizable plate members 106 of the headrest 102. As described previously, each of the plurality of magnets 110a, 110b includes a base 118 and a protrusion 120 extending from the base 118 such that the protrusion 120 has a cross-section smaller than a cross-section of the base 118. In this example, the magnet protrusion 120 is circular while the base 118 is cuboid. However, it will be appreciated that the protrusion 120 and base 118 may have different shapes in alternate embodiments. Each magnet 110a, 110b, 110c, 110d has a body shaped with different cross-sections so that the carrier member 202 can secure the magnet 110a, 110b, 110c, 110d inside the cushion 108 by retaining the base of the magnet 110a, 110b, 110c, 110d while allowing the protrusion to be as close to the magnetizable plate members 106 (FIG. 1A) as possible to maximise the attractive forces.

The carrier member 202 may be a resilient material and includes a plurality of cavities 204a, 204b, corresponding to the plurality of magnets 110a, 110b, 110c, 110d. Each cavity 204 includes an opening 205a, 205b, 205c, 205d sized based on the cross-section of the protrusion 120. In this way, the magnets 110a, 110b, 110c, 110d are disposed in the cavities 204a, 204b such that the protrusion 120 of each magnet is snugly received by a respective opening 205a, 205b, 205c, 205d.

The cushion 108 may also include a plurality of recesses 206a, 206b, 206c, 206d corresponding to the plurality of cavities 204a, 204b. Each recess 206 is sized based on the cross-section of the base 118 and a layer of resilient material forming the cavities 204a, 204b surrounding the base 118, whereby the magnets 110a, 110b, 110c, 110d together with the resilient material are disposed in the recesses 206a, 206b, 206c, 206d such that the base 118 of each magnet 110 together with the resilient material is snugly received by a respective recess 206.

In an alternative embodiment, the magnets 110a, 110b, 110c, 110d can be shaped with a uniform cross-section and fixedly mounted onto the plurality of recesses 206a, 206b, 206c, 206d so that the magnets 110a, 110b, 110c, 110d remain in position when the cushion 108 is magnetically attached to the headrest 102. Accordingly, the magnets 110a, 110b, 110c, 110d can have other shapes and sizes such that they are in proximity to the magnetizable plate members 106.

The carrier member 202 may be removably attached to the cushion 108 via attaching means 208. The attaching means 208 may be conventional attaching means, for example Velcro, but can include other types such as tape or pin-and-hole to securely attach the carrier member 202 to the cushion 108. In an example embodiment, the carrier member 202 can be designed with multiple undercuts and holes 210 to create sufficient mechanical bonding with the cushion 108. The carrier member 202 can also include apertures 214 which may reduce the presence of trapped air during over-molding to provide the user a softer feeling.

FIG. 2B shows a perspective view of the assembled cushion 108 of the head support assembly 100 of FIG. 1A, according to an example embodiment. In FIG. 2B, the plurality of magnets 110a, 110b, 110c, 110d are assembled into the recesses 206a, 206b, 206c, 206d of the cushion 108. The magnet protrusions 120 are received by the openings 205a, 205b, 205c, 205d of the carrier member 202 such that they are flushed with an aft surface 212 of the carrier member 202. When assembled, the aft surface 212 of the carrier member 202 and the aft section 114 of the cushion 108 are also flushed and substantially flat to allow strong magnetic interaction between the magnets 110a, 110b, 110c, 110d and the magnetizable plate members 106. The magnet protrusions 120 are thus proximate to one or more magnetizable plate members 106 (shown in FIG. 1A). The strong magnetic attraction may thus prevent the cushion 108 from sagging or falling off from the magnetizable plate members 106 as the centre of gravity is closer to a magnetic plane.

FIG. 2C shows a rear view of the assembled cushion 108 of FIG. 2B while FIG. 2D shows a cross-sectional view taken about the line A-A of the assembled cushion 108 of FIG. 2C, according to an example embodiment. In FIG. 2D, the carrier member 202 is shaped and disposed within the recesses 206a, 206b, 206c, 206d while securely retaining the plurality of magnets 110a, 110b within the plurality of cavities 204a, 204b. This may ensure that the protrusions 120c, 120d are flushed with the aft section 114 of the cushion 108, resulting in the magnets 110a, 110b being proximate to the one or more magnetizable plate members 106 (shown in FIG. 1A).

FIG. 2E shows an exploded perspective view of a carrier member 216 of the head support assembly 100 of FIG. 1A according to an alternate embodiment, while FIG. 2F shows a perspective view of the assembled carrier member 216 of FIG. 2E. In this embodiment as shown in FIG. 2E, the carrier member 216 is configured to receive two magnet assemblies 218a, 218b. Each of the two magnet assemblies 218a, 218b includes a base 220a, 220b and a protrusion 222a, 222b extending from the base 220a, 220b. In a non-limiting implementation, the base 220a, 220b comprises a steel plate while the protrusion 222a, 222b comprises a permanent magnet. The magnet may be fixedly attached to the steel plate using an adhesive or bonder such as Loctite 326. The carrier member 216 may be removably attached to the aft section 114 and configured to securely retain the magnet assemblies 218a, 218b such that the magnet assemblies 218a, 218b are disposed at the aft section 114 proximate to the one or more magnetizable plate members 106 of the headrest 102.

The carrier member 216 also includes a plurality of cavities 224 corresponding to the magnet assemblies 218a, 218b. Each cavity 224 includes an opening 226a, 226b sized based on the cross-section of the protrusion 222a, 222b. In this way, the magnet assemblies 218a, 218b are disposed in the cavities 224 such that the protrusion 222a, 222b of each magnet is snugly received by a respective opening 226a, 226b, as shown in FIG. 2F.

FIG. 2G shows an exploded perspective view of a carrier member 228 of the head support assembly 100 of FIG. 1A according to an alternate embodiment, while FIG. 2H shows a perspective view of the assembled carrier member 228 of FIG. 2G with the cushion 108 of FIG. 2A. The carrier member 228 in this embodiment is configured to receive two magnet assemblies 230a, 230b. The carrier member 228 includes a plurality of cavities 232b with openings 234a, 234b corresponding to the shape of the magnet assemblies 230a, 230b. The two magnet assemblies 230a, 230b may be of similar shape/construction to the magnet assemblies 110a, 110b of FIG. 2A but may have a higher magnetic strength. Accordingly, the carrier member 228 can have a smaller width compared to the carrier member 216 of FIG. 2E. The cushion 108 may therefore be lighter and contribute to reducing the overall weight of the cushion assembly.

FIG. 3 shows a perspective view 300 of the headrest 102 and one or more magnetizable plate members 106 of the head support assembly 100 of FIG. 1A, according to an example embodiment. As shown in FIG. 3, the headrest 102 is formed as part of the seatback 104. In other embodiments, the headrest 102 may be removable from the seatback 104 and can be adjusted vertically relative to the seatback 104. The one or more magnetizable plate members 106 shown in FIG. 3 includes a pair of rails parallel to a height direction of the seatback 104 such that the cushion 108 can be moved vertically along the headrest 102. In alternate embodiments, the one or more magnetizable plate members 106 may be a single metallic (for example, steel) piece which can allow the cushion 108 to be adjusted both vertically and horizontally relative to the seatback 104. In example embodiments, the size and/or position of the one or more magnetizable plate members 106 may be varied. For example, the one or more magnetizable plate members 106 may have longer rails to accommodate a greater vertical adjustability of the cushion 108.

The plate members 106 may be embedded to the headrest 102 at a predetermined depth such that headrest 102 can be aesthetically appealing while maintaining the magnetic attractive force of the magnets 110a, 110b, 110c, 110d to the plate members 106 at the same time. The position and the dimension (such as length and width) of the plate members 106 may be predetermined to indicate a position and adjustable range of the cushion 108 when it is attached to the headrest 102. For example, the plate members 106 can be positioned at a predetermined specific depth and position using guides and spacers inside a foam tool during over-molding with the fore surface 116 of the headrest 102.

In alternate embodiments, the plate members 106 can be embedded into the fore surface 116 to provide a better experience so that users will not feel the existence of the plate members 106 in the headrest 102 when leaning against it in the absence of the cushion 108. The embedment depth of the plate members 106 can be controlled to provide sufficient magnetic force interaction with the magnets 110a, 110b, 110c, 110d. The plate members 106 can also be positioned in the headrest 102 such that they are not in direct contact with a user's head. The thickness of the plate members 106 can be optimized by considering the overall weight of the product and the strength of magnetic force interaction with the magnets 110a, 110b, 110c, 110d.

In another example embodiment, the plate members 106 may be embedded in the cushion 108 while the magnets 110a, 110b, 110c, 110d are embedded in the headrest 102 near the fore surface 116. Such an arrangement still allows the cushion 108 to be magnetically attached to the headrest 102 and yet adjustable between different position relative to the headrest 102.

In another embodiment, the magnets may be installed on a steel plate which is then embedded in the cushion 108. Such an arrangement allows small magnets to be used while still providing the cushion 108 with adjustability relative to the headrest 102, as the steel plate embedded in the cushion 108 is magnetized by the magnets and can interact with the plate members 106 embedded in the headrest 102 to magnetically attach the cushion 108 to the headrest 102.

FIG. 4 shows a flowchart 400 illustrating a method of supporting a cushion on a headrest, according to an example embodiment. The method comprises, at step 402, embedding one or more magnetizable plate members into the headrest, the headrest extending upwardly from a seatback. At step 404, the method comprises disposing a plurality of magnets in the cushion and at step 406, the method comprises placing the cushion against the headrest such that the one or more magnetizable plate members and the plurality of magnets magnetically attach the cushion to the headrest for supporting the cushion at the first or second position.

The method of placing the cushion against the headrest may include slidingly abutting the aft section with a substantially flat fore surface of the headrest. Disposing the plurality of magnets in the cushion may include securely retaining magnets in the carrier member at the aft section proximate to the one or more magnetizable plate members of the headrest. Embedding the one or more magnetizable plate members into the headrest may include positioning the one or more magnetizable plate members adjacent the fore surface of the headrest.

Disposing the plurality of magnets in the cushion may include forming in the carrier member a plurality of cavities corresponding to the plurality of magnets, each cavity comprising an opening sized based on the cross-section of the protrusion; and disposing the magnets in the cavities such that the protrusion of each magnet is snugly received by a respective opening. Disposing the plurality of magnets in the pillow may further include positioning the magnets based on a position of the one or more plate member on the headrest.

The head support assembly 100 as described herein may provide a clean and neat device that can allow users to adjust to their desired position and held in place without the need for constant re-positioning. The head support assembly is durable and can also be used for prolonged a period of time as the magnetic strength is not easily lost.
