It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments of the present disclosure are not to be considered as limiting, unless the claims expressly state otherwise.

[0027] The terms "comprise", "comprises", or "comprising" or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element preceded by "comprises... a" does not, without further constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0028] Referring now to the drawings Figures 1 to 17 , reference numeral 10 generally designates a patient support apparatus 10 having a frame assembly 12 including an upper frame 14 operatively coupled to a base frame 16. The upper frame 14 has an upper support surface 18 and a lower surface 20 opposite the upper support surface 18. A first side surface 22 and a second side surface 24 extend between the upper support surface 18 and the lower surface 20. The first side surface 22 and the second side surface 24 are generally opposite lateral side surfaces of the upper frame 14. A surface assembly 26 is selectively positioned on the upper support surface 18 of the upper frame 14. The surface assembly 26 includes an outer cover or pad 28 to which a harness 30 is coupled. The harness 30 includes first harnesses 32a, 32b (collectively, first harnesses 32) extending from a first side of the outer pad 28 and second harnesses 34a, 34b (collectively, second harnesses 34) extending from a second side of the outer pad 28. The first side is opposite the second side.

[0029] The first strap connectors 40 (including first strap connectors 40a, 40b) are coupled to the first straps 32a, 32b, and the second strap connectors 42 (including second strap connectors 42a, 42b) are coupled to the second straps 34a, 34b. The strap connectors 40, 42 are coupled to distal ends 44 of the first straps 32a, 32b and the second straps 34a, 34b, respectively. The docking connectors 46, 48 are coupled to at least one of the upper frame 14 and the outer mattress 28. The first straps 32a, 32b and the second straps 34a, 34b are configured to extend along the first side surface 22 and the second side surface 24 of the upper frame 14, and the strap connectors 40, 42 are configured to engage the docking connectors 46, 48, respectively, to couple the surface assembly 26 to the upper frame 14. The engagement between the strap connectors 40 and the docking connectors 46, 48 is configured to allow sliding engagement between the upper support surface 18 and the outer mattress 28 as the upper frame 14 is articulated between a plurality of positions.

[0030] Figures 1 to 4 The surface assembly 26 is shown, and the patient support apparatus 10 is configured as a hospital bed. In examples of a hospital bed, the support apparatus 10 includes a frame assembly 12 with a base frame 16 coupled to an upper frame 14. The upper frame 14 is adjustable (e.g., raise, lower, tilt, etc.) relative to the base frame 16. Additionally, the upper frame 14 generally includes a plurality of sections 60, 62, 64 that are independently adjustable relative to one another. These sections 60, 62, 64 generally include a head end section 60 (also referred to as a head and thorax section or a head section 60), a base or seat section 62, and a foot section 64 (also referred to as a foot end section 64). The sections 60, 62, 64 are configured to move relative to one another to allow the upper frame 14 to be articulated between a plurality of positions (e.g., a head elevated region or bed head elevated position, a foot lowered region, etc.). The support apparatus 10 includes actuation assemblies 66, 68 for adjusting the position of the upper frame 14 relative to the base frame 16 and for adjusting the position of the sections 60, 62, 64 of the upper frame 14 relative to one another. The base frame 16 includes casters 70 for moving the hospital bed relative to an underlying floor. The hospital bed also includes bed rails 72 that are generally adjustable between a raised position and a lowered position.

[0031] The upper frame 14 (also referred to as a platform) forms a support surface 18 that selectively supports the surface assembly 26. An underside 20 of the upper frame 14 is opposite the support surface 18 and generally faces the base frame 16 and an underlying floor. The first side surface 22, the second side surface 24, and the first end surface 80, the second end surface 82 extend between the support surface 18 and the underside 20.

[0032] The surface assembly 26 is configured to be coupled or removably attached to the upper frame 14. The support surface 18 can assume different shapes based on movement of the sections 60, 62, 64, which can affect the position of the support surface 18 as described herein. The attachment system 90, generally including the straps 30 (i.e., the first straps 32a, 32b and the second straps 34a, 34b), the strap connectors 40, and the docking connectors 46, 48, facilitates coupling of the surface assembly 26 to the upper frame 14 while allowing predefined slippage between the support surface 18 and the upper frame 14 as the upper frame 14 articulates between the plurality of positions.

[0033] The surface assembly 26 includes an outer pad 28 that defines an interior. The surface assembly 26 can include various components in the interior, such as, but not limited to, a pneumatic system 92, a Micro-Climate Management (MCM) layer, support foam, etc. The straps 30 of the attachment system 90 are coupled to the outer pad 28. The straps 30 can generally be secured to the outer pad. In some aspects, the first straps 32a, 32b and the second straps 34a, 34b are welded to the outer pad 28, and more particularly, Radio Frequency (RF) welded to the outer pad 28. RF welding the first straps 32a, 32b and the second straps 34a, 34b to the outer pad 28 increases the seam strength between the outer pad 28 and the first straps 32a, 32b and the second straps 34a, 34b. The welding also creates a flexible attachment that couples the surface assembly 26 to the frame assembly 12 while allowing some movement and reducing the bunching phenomenon described herein.

[0034] The welding also attaches the first straps 32a, 32b and the second straps 34a, 34b to the outer pad 28 without creating holes, openings, or perforations in the outer pad 28 (e.g., no openings in the outer pad 28 are traversed by the seams), as stitching connections often do, which can allow fluid ingress into the mattress. As such, the welded attachment between the first straps 32a, 32b and the second straps 34a, 34b and the outer pad 28 is fluid-tight, thereby creating a self-contained surface assembly 26.

[0035] Alternatively, the straps 30 can be sewn to the outer pad 28. Sewing can increase manufacturing efficiency while providing a connection that allows the surface assembly 26 to move slightly, thereby reducing the bunching phenomenon. It is also contemplated that the straps 30 can be removable such that the connection between the straps 30 and the outer pad 28 can be a semi-permanent or temporary connection. Different areas or units of a healthcare facility can use different connection methods for the straps 30 of the surface assembly 26.

[0036] Furthermore, the outer pad 28 may be moisture-proof and / or air-proof. In a non-limiting example, the outer pad 28 may be made of nylon or polyester material coated with a moisture-permeable polyurethane coating. This configuration may be advantageous if the surface assembly 26 has an MCM layer. The MCM layer typically consists of a spacer material and a blower, which is typically included in the control assembly 94 and pneumatic system 92 of the MCM layer. The blower is configured to direct air through the spacer material to cool the patient's skin and wick away moisture.

[0037] In another non-limiting aspect, the outer sheet 28 may be impermeable to both fluid and moisture, resulting in almost no fluid flowing through the outer sheet 28. The outer sheet 28 and the welded straps 30 then form a separate fluid-resistant surface assembly 26, which may help reduce the entry of fluids, contaminants, etc., into the interior of the surface assembly 26 in a medical environment.

[0038] Still refer to Figures 1 to 4 The surface assembly 26 typically has two first straps 32a and 32b, which, for clarity, may be referred to herein as a first left strap 32a and a first right strap 32b. The surface assembly 26 also typically has two second straps 34a and 34b, which, for clarity, may be referred to herein as a second left strap 34a and a second right strap 34b. The first straps 32a and 32b are positioned closer to the head end 100 of the surface assembly 26, and the second straps 34a and 34b are positioned closer to the foot end 102 of the surface assembly 26. The left straps 32a and 34a extend from a first side surface 110 of the outer pad 28 (illustrated as the left side surface), and the right straps 32b and 34b extend from a second side surface 112 of the outer pad 28 (illustrated as the right side surface). It is also conceivable, as detailed herein, that the strap 30 may extend from the bottom surface 114 of the outer sheet 28, which would both allow the sheet to be tucked around the surface assembly 26 and facilitate the use of the attachment system 90 with the different support devices 10 described herein.

[0039] As shown in the figure, the first bands 32a, 32b and the second bands 34a, 34b are arranged as mirror images of each other about the centerline 118 of the surface assembly 26. However, one or both of the second bands 34a, 34b may be offset relative to the first bands 32a, 32b, and / or one or both of the left bands 32a, 34a may be offset relative to the right bands 32b, 34b. This offset configuration helps the surface assembly 26 to be properly aligned on the upper frame 14 (e.g., the head end 100 on the head end segment 60, etc.) and / or aligned with the mating connectors 46, 48 to properly position the various components of the surface assembly 26 used for treating the patient. The offset configuration can provide caregivers with an indication of the orientation of the surface assembly 26 relative to the upper frame 14. Other indicators may also be provided without departing from the teachings herein, such as distinguishing the first band 32 from the second band 34.

[0040] The first straps 32a, 32b and the second straps 34a, 34b can be made of an elastic or stretch material. The elastic material of the straps 30 can allow for convenient installation of the surface assembly 26 and / or the straps 30 to maintain tension when the straps 30 engage the docking connectors 46, 48 to assist in securing the surface assembly 26 to the top frame 14. Having the straps 30 with elastic qualities can advantageously allow the straps 30 to conform closely around the top frame 14 to reduce or prevent excess strap length between the top frame 14 and the bottom frame 16. Additionally, the elastic straps 30 can hold the surface assembly 26 more securely to the top frame 14. Furthermore, the elastic material of the straps 30 can assist a caregiver in installing the surface assembly 26 by allowing the caregiver to stretch the straps 30 to engage the docking connectors 46, 48 and allow the straps 30 to recover tension after being engaged securely.

[0041] Additionally or alternatively, the first straps 32a, 32b and the second straps 34a, 34b can be made of a durable, easy-to-clean material or fabric, such as a 210 denier (210D) coated material, such as nylon. Furthermore, the first straps 32a, 32b and the second straps 34a, 34b or the left straps 32a, 34a and the right straps 32b, 34b can be made of different materials based on the configuration of the attachment system 90.

[0042] Still referring to Figures 1 to 4 Each strap 30 includes a respective strap connector 40 at the distal end 44 thereof. The strap connector 40 can be coupled, integrated, or embedded to the strap 30. The specific relationship between the strap 30 and the strap connector 40 can depend on the configuration of the attachment system 90, including the configuration and / or location of the strap connector 40 and the docking connector 46, 48.

[0043] Still referring to Figure 2 And Figure 3 In various examples, the strap connectors 40a, 40b on the first straps 32a, 32b (also referred to as first strap connectors 40a, 40b) are configured to engage or dock with each other, and the strap connectors 42a, 42b on the second straps 34a, 34b (also referred to as second strap connectors 42a, 42b) are configured to engage with each other. In such examples, the docking connectors 46, 48 are configured as right strap connectors 40b, 42b, such that separate docking connectors 46, 48 can be omitted from the attachment system 90. The engagement between the first straps 32a, 32b and the engagement between the second straps 34a, 34b are located on the side of the top frame 14 opposite the outer pad 28 to couple the surface assembly 26 to the top frame 14.

[0044] Generally, the first strap connectors 40a, 40b are configured to engage one another, and the second strap connectors 42a, 42b are configured to engage one another proximate or adjacent the lower surface 20 of the upper frame 14. For clarity, the strap connectors 40a, 42a on the left straps 32a, 34a can be referred to as left strap connectors 40a, 42a, and the strap connectors 40b, 42b on the right straps 32b, 34b can be referred to as right strap connectors 40b, 42b.

[0045] In various examples, the surface assembly 26 is positioned on the support surface 18 of the upper frame 14. The left straps 32a, 34a extend from the outer pad 28 along the first side surface 22 of the upper frame 14 and along the lower surface 20 of the upper frame 14 toward the second side surface 24. The right straps 32b, 34b extend from the outer pad 28 along the second side surface 24 of the upper frame 14 and along the lower surface 20 toward the first side surface 22.

[0046] In various aspects, the first straps 32a, 32b and the second straps 34a, 34b can have substantially similar lengths. Alternatively, one of the first straps 32a, 32b or one of the second straps 34a, 34b can be longer to adjust the engagement position between the opposing straps 30. This can allow the engagement position between the first strap connectors 40a, 40b and / or the second strap connectors 42a, 42b to be proximate or adjacent one of the side surfaces 22, 24, which can be more convenient for a caregiver to access to install the surface assembly 26.

[0047] Additionally, some or all of the strap connectors 40, 42 can be moveable along the length of the respective strap 30. This can allow the engagement position relative to the centerline 118 and / or the length of the strap 30 to be adjusted. The adjustable length can facilitate adjusting the tension of the straps 32, 34 around the upper frame 14 to better secure the surface assembly 26. Additionally or alternatively, one or both of the first straps 32a, 32b and one or both of the second straps 34a, 34b can have a plurality of strap connectors 40 arranged along the length of the strap 30. This configuration can allow different engagement positions to be achieved with the mating strap connectors 40. This can facilitate the surface assembly 26 being used with different support devices 10.

[0048] Still referring to Figure 2 and Figure 3In various non-limiting examples, the left strap connectors 40a, 42a are magnets and the right strap connectors 40b, 42b are counter-magnets. In such examples, the magnets engage one another proximate the lower surface 20 of the upper frame 14. The magnets and counter-magnets can be permanent magnets of opposite polarity. In further non-limiting examples, the left strap connectors 40a, 42a are magnets and the right strap connectors 40b, 42b are metal or metal components that are magnetically attracted to the magnets to operatively couple the first and second straps 32a, 32b and 34a, 34b. It is also contemplated that the left strap connectors 40a, 42a are metal or metal components and the right strap connectors 40b, 42b are magnets.

[0049] Further, the left strap connectors 40a, 42a and / or the right strap connectors 40b, 42b can be electromagnets. It is contemplated that both the first and second straps 32a, 32b and 34a, 34b include electromagnets, the first and second straps 32a, 32b include electromagnets and the second straps 34a, 34b include permanent magnets or metal components, or the second straps 34a, 34b include electromagnets and the first straps 32a, 32b include permanent magnets or metal components.

[0050] Additionally or alternatively, the first strap connectors 40a, 40b and the second strap connectors 42a, 42b can be counter hook and loop fasteners. In illustrative examples, the left straps 32a, 34a include hooks and the right straps 32b, 34b include loops. The hook and loop fasteners can be provided at the distal ends 44 of the first and second straps 32a, 32b and 34a, 34b, arranged in spaced segments along the lengths of the first and second straps 32a, 32b and 34a, 34b, and / or extend for a majority or all of the lengths of the first and second straps 32a, 32b and 34a, 34b. In other non-limiting examples, the first strap connectors 40 and the second strap connectors 42 can be buckle fasteners, lacing assemblies, harness-style connectors, clamps, snap features, grommet connectors, and the like.

[0051] The surface assembly 26 includes straps 30 having left connectors 40a, 42a configured to engage right connectors 40b, 42b around the upper frame 14. In this regard, the straps 30 couple the surface assembly 26 to the frame assembly 12. Further, the surface assembly 26 can be coupled to a variety of types and configurations of frame assemblies 12 because the surface assembly 26 does not utilize specific components of the frame assembly 12 to couple to the upper frame 14. The straps 30 can extend from the side surfaces 110, 112 of the outer pad 28, which can include a bend or seam between the side surfaces 110, 112 and the bottom surface 114, and thereby along the side surfaces 22, 24 of the upper frame 14.

[0052] In review Figure 4 and Figure 5 and Figure 6In various examples, the attachment system 90 includes docking connectors 46, 48 configured as frame connectors 130, 132 that can be coupled or integrated to the frame assembly 12. Generally, the frame connectors 130 include frame connectors 130a, 130b and the frame connectors 132 include frame connectors 132a, 132b. During manufacturing, the frame connectors 130, 132 are coupled to an outer surface of the upper frame 14 and can be integrated or incorporated into the upper frame 14. The frame connectors 130, 132 are arranged on the upper frame 14 to respectively dock with the strap connectors 40, 42. The first strap connector 40 and the second strap connector 42 are configured to engage the corresponding frame connectors 130, 132.

[0053] The frame connectors 130, 132 are positioned to engage the strap connectors 40, 42. The straps 30 can have different lengths or the strap connectors 40, 42 can have different adjustability to engage the frame connectors 130, 132. Generally, the attachment system 90 includes two first frame connectors 130a, 130b on the head and thorax section 60 and two second frame connectors 132a, 132b on the foot section 64. For clarity, one of the first frame connectors 130 and the second frame connectors 132 is referred to as a first left frame connector 130a and a second left frame connector 132a arranged on a first side (e.g., illustrated as a left side) of a centerline 140 of the upper frame 14 and the other of the first frame connectors 130 and the second frame connectors 132 is referred to as a first right frame connector 130b and a second right frame connector 132b arranged on a second side (e.g., illustrated as a right side) of the centerline 140 of the upper frame 14.

[0054] The left frame connectors 130a, 132a are generally mirror image arrangements of the right frame connectors 130b, 132b. However, based on the arrangement of the straps 30, one or both of the left frame connectors 130a, 132a can be offset relative to the right frame connectors 130b, 132b. This can help to properly position the surface assembly 26 on the upper frame 14. In addition, the frame connectors 130, 132 on the head end section 60 and the foot end section 64 help to couple the surface assembly 26 proximate the head end 100 and the foot end 102, which can reduce or prevent twisting or sliding of the ends 100, 102 of the surface assembly 26 relative to the upper frame 14 that can be caused by a caregiver, a patient, or the like.

[0055] Still referring to Figures 4 to 6Frame connectors 130 and 132 can be positioned in various locations, such as near the centerline 140, off-center between the centerline 118 and the side surfaces 22 and 24, or close to the side surfaces 22 and 24. In some respects, frame connectors 130 and 132 are positioned adjacent to or located on opposite side surfaces 22 and 24 of the upper frame 14. For example, frame connectors 130 and 132 can be coupled to the lower surface 20, which is less than 10 inches from the side surfaces 22 and 24. Positioning frame connectors 130 and 132 adjacent to or located on the side surfaces 22 and 24 allows for easier access by caregivers, facilitates the engagement of strap connectors 40 and 42 to frame connectors 130 and 132, and reduces interference of the strap 30 with the operation of the frame assembly 12. Additionally, the frame connectors 130, 132 located on or adjacent to the side surfaces 22, 24 will help provide visual feedback to caregivers that the surface assembly 26 has been correctly mounted on the frame assembly 12 (i.e., the strap connectors 40, 42 engage with the frame connectors 130, 132).

[0056] As shown in the figure, the strap 30 extends from the side surfaces 110, 112 of the outer sheet 28. It is also conceivable, as detailed herein, that the strap 30 may extend from the bottom surface 114 of the outer sheet 28. In such examples, the strap 30 may extend from the bottom surface 114 of the outer sheet 28, along the support surface 18, around the side surfaces 22, 24, and along the lower surface 20 to engage the mating frame connectors 130, 132. This configuration is advantageous both for tucking the sheet around the surface assembly 26 and, as described herein, for use with various support devices 10.

[0057] In all aspects, such as Figure 4 and Figure 5 As shown, frame connectors 130 and 132 are coupled to the lower surface 20 of the upper frame 14. This facilitates both concealing the engagement point between the strap connector 40 and the frame connectors 130 and 132 and moving the engagement point to an area normally inaccessible to the patient. In this example, the left straps 32a and 34a extend from the first side surface 110 of the outer pad 28, along the first side surface 22 of the upper frame 14, and along the lower surface 20 of the upper frame 14 to engage the left frame connectors 130a and 132a. Similarly, the right straps 32b and 34b extend from the second side surface 112 of the outer pad 28, along the second side surface 24 of the upper frame 14, and along the lower surface 20 of the upper frame 14 to engage the right frame connectors 130b and 132b.

[0058] like Figure 6 As shown, in some non-limiting aspects, frame connectors 130, 132 are coupled to the side surfaces 22, 24 of the upper frame 14. In such examples, compared to frame connectors 130, 132 located on the lower surface 20 (Figure 4 and Figure 5 ) or the strap connectors 40, 42 engage each other ( Figure 2 and Figure 3 ), the strap 30 can have a shorter length and can be biased or contracted to a shorter length. Moreover, moving the frame connectors 130, 132 to the side surfaces 22, 24 can facilitate improved visibility of the engagement location for a caregiver to engage the strap connectors 40, 42 with the frame connectors 130, 132 and confirm proper installation of the surface assembly 26.

[0059] The strap connectors 40, 42 and the frame connectors 130, 132 can have a configuration similar to that described with respect to Figure 2 and Figure 3 . The strap connectors 40, 42 can be movable along the length of the respective strap 30. Additionally or alternatively, one or both of the first strap 32a, 32b and the second strap 34a, 34b can have a plurality of strap connectors 40, 42 disposed along the length of the strap 30. This can allow for adjustment of the strap 30 for different locations of the frame connectors 130, 132, such as on different frame assemblies 12. Moreover, as described herein, the strap 30 can be operatively coupled to a contraction assembly 150 ( Figure 16 ).

[0060] Still referring to Figures 4 to 6 , in certain aspects, the strap connectors 40, 42 and the frame connectors 130, 132 can be hook and loop fasteners. In such examples, the surface assembly 26 is positioned on the upper frame 14 and the strap 30 extends along the respective side surface 22, 24 of the upper frame 14. The caregiver can then engage the strap connectors 40, 42 to the frame connectors 130, 132 on the side surface 22, 24 or the lower surface 20. The hook and loop fasteners can be provided at the distal end 44 of the first strap 32a, 32b and the second strap 34a, 34b, spaced apart along the length of the first strap 32a, 32b and the second strap 34a, 34b and / or extend for a majority or all of the length of the first strap 32a, 32b and the second strap 34a, 34b. In additional non-limiting examples, the first strap connector 40 and the second strap connector 42 can be a buckle, a lacing assembly, a harness-style connector, a clamp, a snap feature, a grommet connector, etc.

[0061] Moreover, the strap connectors 40, 42 and the frame connectors 130, 132 can be permanent magnets of opposite polarity or a combination of permanent magnets and metal components that are magnetically attracted to the magnets. In examples where both the frame connectors 130, 132 and the strap connectors 40, 42 are magnets or one of the frame connectors 130, 132 and the strap connectors 40, 42 is a magnet, the magnetic field of the magnets can be sufficient to enable automatic installation of the surface assembly 26.

[0062] In one non-limiting illustration, the frame connectors 130, 132 are permanent magnets whose magnetic fields can extend to or near the side surfaces 22, 24 of the upper frame 14 to attract components such as the strap connectors 40, 42. In other words, the magnetic fields of the frame connectors 130, 132 can magnetically attract components that extend adjacent to or along the side surfaces 22, 24 of the upper frame 14. In this way, when a caregiver positions the surface assembly 26 on the upper frame 14, the strap 30 extends downward, along or near the side surfaces 22, 24 of the upper frame 14, the strap connectors 40, 42 can be drawn toward or to the frame connectors 130, 132 by the magnetic fields of the frame connectors 130, 132. In such a strong magnetic field, the frame connectors 130, 132 can cause automatic engagement with the strap connectors 40, 42, which in turn causes automatic installation of the surface assembly 26 after the surface assembly 26 is positioned on the support surface 18.

[0063] Still referring to Figures 4 to 6 In this way, positioning the surface assembly 26 on the support surface 18 with the strap 30 hanging downward (e.g., not clamped under the surface assembly 26) brings the strap connectors 40, 42 into the magnetic field range of the frame connectors 130, 132 to allow the strap connectors 40 to move toward and ultimately engage the frame connectors 130, 132 without the caregiver having to actively or manually move the strap 30. This can facilitate more efficient and convenient installation of the surface assembly 26 on the frame assembly 12. The frame connectors 130, 132 in such a magnetic field can be located on the side surfaces 22, 24 or on the lower surface 20. It is also contemplated that magnets with automatic installation attractive magnetic fields can be located on the strap 30 without departing from the teachings herein.

[0064] In the example where the frame connectors 130, 132 are magnets, the attachment system 90 can include a cover 156. Generally, the attachment system 90 can have one cover 156 per magnet, but other configurations are contemplated. The cover 156 can be operably coupled to the frame assembly 12 to extend over the magnets and provide a barrier over and / or around the magnetic frame connectors 130, 132. This barrier can reduce or prevent the magnetic fields from extending beyond the cover 156, thereby reducing or preventing any potential interference with other objects in the medical facility or patient room. Generally, the cover 156 is made of a metallic material.

[0065] For example, certain machines or equipment can be affected by magnetic fields. When using such machines or equipment, the cover 156 can be moved over the frame connectors 130, 132 to block the magnetic field, thereby reducing or preventing any impact on the operation of the machine or equipment. The cover 156 can be coupled to the frame assembly 12 in a pivoting, hinged, rotating, sliding, snapping, hooking, or other manner that allows the cover 156 to move between a covered position over the frame connectors 130, 132 and an uncovered position.

[0066] The band connectors 40, 42 and the frame connectors 130, 132 are either magnets or examples where the band connectors 40, 42 and the frame connectors 130, 132 are to remain engaged, the cover 156 can be configured to extend over the band connectors 40, 42 and the frame connectors 130, 132 when the band connectors 40, 42 and the frame connectors 130, 132 are engaged. As such, the cover 156 can be shaped to match the connectors 40, 42, 130, 132 while providing a barrier over and around the engaged connectors 40, 42, 130, 132. Such a configuration can facilitate maintaining engagement between the band 30 and the upper frame 14 while also allowing for components that can be affected by magnetic fields.

[0067] In further non-limiting examples, at least one of the band connectors 40, 42 and the frame connectors 130, 132 can be an electromagnet. The electromagnet can be operably coupled to one or more activation switches 170 for adjusting the electromagnet between an activated state, emitting a magnetic field, and a deactivated state. By way of illustration, the frame connectors 130, 132 can be configured as electromagnets and the band connectors 40, 42 can be permanent magnets or metallic components that can be magnetically attracted to the electromagnets when activated. In examples employing electromagnets, the attachment system 90 can further include the cover 156 to allow the electromagnets to be activated and engage the band connectors 40, 42 while reducing the impact of the magnetic field on other equipment or machines.

[0068] Furthermore, it is also contemplated that the band connectors 40, 42 can engage docking connectors 46, 48 on the upper support surface 18. In such examples, the frame connectors 130, 132 can be coupled to the support surface 18, generally adjacent the side surfaces 22, 24 of the upper frame 14. The band 30 can extend from the bottom surface 114 or the side surfaces 110, 112. The band 30 extends between the bottom surface 114 and the support surface 18 to engage the frame connectors 130, 132.

[0069] Still referring to Figures 4 to 6The surface assembly 26 includes a harness 30 having left harness connectors 40a, 42a that engage with the left frame connectors 130a, 132a and right connectors 40b, 42b that engage with the right frame connectors 130b, 132b. The surface assembly 26 is coupled to the frame assembly 12 by engagement between the harness connectors 40, 42 and the frame connectors 130, 132. The harness 30 can be elastic or associated with a retraction assembly 150 to adjust the harness 30 to different or alternating positions of the frame connectors 130, 132. The surface assembly 26 can be coupled to frame assemblies 12 of various types and configurations.

[0070] Referring to Figures 7 to 16 In various aspects, the support device 10 includes a frame assembly 180 having a bottom frame 182 and an upper frame 184 that features facilitate maintaining engagement with the surface assembly 26. The frame assembly 180 is generally similar in configuration and operation to the frame assembly 12 shown in Figures 2 to 6 The upper frame 184 shown in

[0071] Similar to the arrangement of the frame connectors 130, 132 shown in Figures 4 to 6 The upper frame 184 shown in Figures 7 to 16 For clarity, one of each of the first and second slots 190, 192 is referred to as a first left slot 190a and a second left slot 192a, arranged on a first side (e.g., illustrated as the left side) of the centerline 140 of the upper frame 184, and the other of each of the first and second slots 190, 192 is referred to as a first right slot 190b and a second right slot 192b, arranged on a second side (e.g., illustrated as the right side) of the centerline 140 of the upper frame 184.

[0072] The left slots 190a, 192a are generally mirror-imaged with the right slots 190b, 192b. However, based on the arrangement of the straps 30, one or both of the left slots 190a, 192a can be offset relative to the right slots 190b, 192b. This can help to properly position the surface assembly 26 on the upper frame 184. In addition, the slots 190, 192 on the head end segment 60 and the foot end segment 64 help to couple the surface assembly 26 proximate the head end 100 and the foot end 102, which can reduce or prevent misalignment of the ends 100, 102 of the surface assembly 26 from twisting or sliding relative to the upper frame 14.

[0073] The slots 190, 192 generally extend between the end surfaces 80, 82 parallel to the centerline 140 of the upper frame 184. The length of the slots 190, 192 between the head end surface 80 and the foot end surface 82 allows for predefined slippage of the surface assembly 26 relative to the support surface 18 while maintaining overall proper positioning of the surface assembly 26 as described herein.

[0074] The surface assembly 26 includes straps 30 extending from the opposing side surfaces 110, 112 or the bottom surface 114 of the outer mat 28, which extend through the respective slots 190, 192 and engage the docking connectors 46, 48. Generally, the first left strap 32a extends through the first left slot 190a, the first right strap 32b extends through the first right slot 190b, the second left strap 34a extends through the second left slot 192a, and the second right strap 34b extends through the second right slot 192b. Based on the docking connectors 46, 48 and the straps 30, the engagement between the straps 30 and the outer mat 28 and the straps 30 and the upper frame 184 can vary. The straps 30 loop around the side surfaces 22, 24 and through the upper frame 184 to engage the docking connectors 46, 48 (e.g., in a “backpack” configuration).

[0075] Still referring to Figure 8 and Figure 9 The straps 30 include the strap connectors 40, 42 at the distal ends 44 thereof, and the attachment system 90 further includes the docking connectors 46, 48 configured as proximal connectors 200, 202 at proximal portions 204 of the straps 30 (closer to the seams with the outer mat 28) (e.g., both the strap connectors 40, 42 and the docking connectors 46, 48 are provided on the straps 30). As such, the first left strap 32a includes the first left strap connector 40a and the first left proximal connector 200a, and the first right strap 32b includes the first right strap connector 40b and the first right proximal connector 200b. Similarly, the second left strap 34a includes the second left strap connector 42a and the second left proximal connector 202a, and the second right strap 34b includes the second right strap connector 42b and the second right proximal connector 202b.

[0076] A strap 30 extends from the side surfaces 110, 112 of the outer pad 28 along the side surfaces 22, 24 of the upper frame 184. The strap 30 then extends along the lower surface 20 of the upper frame 184 through corresponding slots 190, 192 to encircle and engage proximal connectors 200, 202, respectively. Accordingly, the strap 30 encircles the side surfaces 22, 24 of the upper frame 184, along the lower surface 20, through slots 190, 192, and along the upper support surface 18 of the upper frame 184, so that it self-engages near the side surfaces 22, 24 to couple the surface assembly 26 to the upper frame 184. The strap 30 may also extend from the bottom surface 114 of the outer pad 28. In such an example, the strap 30 extends through slots 190, 192, along the side surfaces 22, 24, and along the upper support surface 18 to engage proximal connectors 200, 202. The strap 30 may extend from the bottom surface 114 near the side surfaces 22, 24 to facilitate engagement of the strap connectors 40, 42 with the proximal connectors 200, 202.

[0077] like Figures 10 to 13 As shown, the attachment system 90 includes strap connectors 40, 42 at the distal end 44 of the strap 30, and mating connectors 46, 48 configured as surface connectors 208, 210. Surface connectors 208, 210 are coupled to or integrated into the outer pad 28, such as the side surfaces 110, 112 of the outer pad 28. Figure 12 ) or bottom surface 114 ( Figure 11 and Figure 13 The bottom surface 114 is the surface that abuts and abuts against the support surface 18 of the upper frame 184. Surface connectors 208 and 210 are generally aligned or correspond to slots 190 and 192, but may be slightly offset relative to slots 190 and 192 without departing from the teachings herein. Accordingly, the first left surface connector 208a is aligned with the first left slot 190a, the first right surface connector 208b is aligned with the first right slot 190b, the second left surface connector 210a is aligned with the second left slot 192a, and the second right surface connector 210b is aligned with the second right slot 192b.

[0078] The strap 30 may extend from the bottom surface 114 of the outer pad 28 rather than from the side surfaces 110, 112. In such examples, the strap 30 is typically positioned on the bottom surface 114 aligned with slots 190, 192. The strap 30 may directly mate with slots 190, 192, or it may be slightly offset relative to slots 190, 192 to minimize the distance the strap 30 extends along the support surface 18 below the surface assembly 26.

[0079] like Figure 11As shown, the strap 30 extends downwards from the bottom surface 114, through slots 190 and 192, along the lower surface 20, and along the outer surfaces 22 and 24, engaging the surface connectors 208 and 210 shown on the bottom surface 114. Thus, the strap 30 extends from the bottom surface 114, surrounds the side surfaces 22 and 24 of the upper frame 184, and engages the surface connectors 208 and 210 on the bottom surface 114 near the point where the strap 30 extends from the bottom surface 114. This configuration facilitates tucking the sheet around the surface assembly 26 without the attachment system 90 touching the sheet. Furthermore, caregivers can easily and conveniently see that the surface assembly 26 is correctly installed on the upper frame 184.

[0080] like Figure 12 As shown, surface connectors 208 and 210 can be coupled to the side surfaces 110 and 112 of the outer pad 28, respectively. In this example, the strap 30 extends from the bottom surface 114, through slots 190 and 192, around the outer surfaces 22 and 24 of the upper frame 184 to the side surfaces 110 and 112 to engage surface connectors 208 and 210. This configuration facilitates both simple and convenient coupling of connectors 40, 42, 208, and 210 and allows caregivers to easily see the coupling location. Caregivers can easily and conveniently see that the surface assembly 26 is correctly installed because the engagement location is on the side surfaces 110 and 112 of the outer pad 28.

[0081] like Figure 14 As shown, surface connectors 208, 210 are typically vertically aligned with slots 190, 192, with straps 30 extending from the side surfaces 110, 112 of the outer pad 28. When the surface assembly 26 is positioned on the upper frame 184, surface connectors 208, 210 are arranged above the corresponding slots 190, 192 for access from below the upper frame 184. This allows caregivers to loop straps 30 around the side surfaces 22, 24 of the upper frame 184 and insert the distal end 44 of straps 30 through slots 190, 192 to engage bottom surface connectors 208, 210, respectively. Frame connectors 130, 132 may extend to most or all of the length of slots 190, 192 to facilitate easier and more efficient engagement between frame connectors 130, 132 and strap connectors 40, 42, which is beneficial in situations with poor visibility below the upper frame 184.

[0082] Reference Figure 14 and Figure 15 In some respects, the strap connectors 40 and 42 engage with each other, similar to Figure 3In such examples, the first strap connectors 40a, 40b and the second strap connectors 42a, 42b (e.g., the docking connectors 46, 48) can be docking features that couple to and engage one another. In such examples, the straps 30 extend from the bottom surface 114 of the outer pad 28 through the respective slots 190, 192. Rather than extending outward, the straps 30 extend inward toward one another to engage the opposing respective strap connectors 40, 42.

[0083] In review Figures 7 to 15 , the strap connectors 40, 42 and the docking connectors 46, 48 (e.g., the opposing strap connectors 40, 42, the proximal connectors 200, 202, and / or the surface connectors 208, 210) can have similar configurations as described herein with respect to Figure 2 , Figure 3 and Figures 4 to 6 . As such, the strap connectors 40, 42, the proximal connectors 200, 202, and the surface connectors 208, 210 can be configured as one or more of: permanent magnets, metal features, electromagnets, hook and loop fasteners, buckles, lacing assemblies, harness-style connectors, clamps, snap features, grommet connectors, etc.

[0084] Still referring to Figures 7 to 15 , the slots 190, 192 in the upper frame 184 can facilitate coupling of the surface assembly 26 to the upper frame 14 and allow for a predefined sliding engagement therebetween. Further, the extension of the straps 30 through the slots 190, 192 can facilitate retaining the surface assembly 26 to the frame assembly 180 in the event of an accidental or incidental disengagement between the connectors. The engagement achieved through the slots 190, 192 provides additional engagement locations for the surface assembly 26 to the frame assembly 180. The surface assembly 26 can be interchangeable between a support device 10 having the upper frame 14 without the slots 190, 192 (e.g., the strap connectors 40, 42 engage one another or engage the frame connectors 130, 132) and a support device 10 having the upper frame 184 with the slots 190, 192 (e.g., the strap connectors 40, 42 engage one another, engage the proximal connectors 200, 202, or engage the surface connectors 208, 210). It is also contemplated that the upper frame 184 having the slots 190, 192 can also include the frame connectors 130, 132 without departing from the teachings herein.

[0085] In review Figures 4 to 6 and Figures 7 to 15It is also contemplated that the attachment system 90 can use both the surface connectors 208, 210 and the frame connectors 130, 132 simultaneously. In such examples, the strap connectors 40, 42 can engage either the surface connectors 208, 210 or the frame connectors 130, 132. Additionally or alternatively, the surface connectors 208, 210 can engage the frame connectors 130, 132 to couple the surface assembly 26 to the frame assembly 12, 180. In such examples, the attachment system 90 can use the surface connectors 208, 210 on the outer pad 28 to engage the frame connectors 130, 132 on the upper support surface 18. The attachment system 90 can utilize the engagement between the surface connectors 208, 210 and the frame connectors 130, 132 and the engagement between the strap connectors 40, 42 and the docking connectors 46, 48 to provide both engagements to couple the surface assembly 26 to the upper frame 14, 184.

[0086] Review Figure 16 And Figures 1 to 15 The attachment system 90 can also include a retraction assembly 150 or a plurality of retraction assemblies 150, one for each of the first straps 32a, 32b and the second straps 34a, 34b. The retraction assembly 150 allows for adjustment of the length of the first straps 32a, 32b and the second straps 34a, 34b. Typically, each retraction assembly 150 can have a ratchet that allows the corresponding strap 30 to be pulled from the retraction assembly 150 and lengthened and held at the increased length. The retraction assembly 150 can also include a spring or other biasing member to allow the ratchet to release and the spring to retract or shorten the strap 30 when the strap 30 is pulled again, thereby pulling the strap 30 into the retraction assembly 150.

[0087] When the attachment system 90 includes a retraction assembly 150, the strap 30 can be thickened at its distal end 44 to accommodate the pulling motion used to adjust the length of the strap 30. The retraction assembly 150 can be disposed within the interior of the outer pad 28 or coupled to the exterior surface of the outer pad 28. The retraction assembly 150 can facilitate placing the strap 30 in tension to hold the position of the surface assembly 26 and reduce excess length of the strap 30 that can interfere with the frame assembly 12, 180 or the caregiver. Allowing for adjustment of the length of the strap 30 can also assist the caregiver in installing the surface assembly 26 and retracting excess length of the strap 30 to secure the surface assembly 26 to the frame assembly 12, 180. The retraction assembly 150 with the strap 30 can be removably coupled to the surface assembly 26, such as the side surfaces 110, 112 of the outer pad 28. This can allow the attachment system 90 to be added to a surface / bed pad that does not originally include the strap 30.

[0088] When using the retraction assembly 150, the belt 30 is configured to retract into the housing of the surface assembly 26 or the retraction assembly 150. Retracting the belt 30 can efficiently and conveniently assist in transporting the surface assembly 26 separate from the frame assembly 12, 180, and more conveniently store the surface assembly 26. The retraction assembly 150 can be used with any configuration of the attachment system 90 and / or support apparatus 10.

[0089] Further, still referring to Figures 1 to 16 , in examples where one or both of the belt connectors 40, 42 and the docking connectors 46, 48 (e.g., the other of the belt connectors 40, 42, the frame connectors 130, 132, the proximal end connectors 200, 202, and / or the surface connectors 208, 210) are examples of electromagnets, the electromagnets can be activated and deactivated by a caregiver via one or more activation switches 170. The activation switches 170 can be located on the frame assembly 12, 180, can be buttons, dials, switches, or other features with which a caregiver can interact to adjust the electromagnets. In such examples, the caregiver can position the surface assembly 26 on the upper frame 14, 184 and switch the electromagnets to an active state via the one or more switches 170 to engage the docking connectors 46, 48. The magnetic field strength of the electromagnets can be sufficient to automatically install the surface assembly 26 as described herein. Without departing from the teachings herein, the frame assembly 12, 180 can have a single activation switch 170 for the electromagnets or multiple activation switches 170.

[0090] Referring to Figure 17 , the electromagnets can also be automatically or controlled by a user interface 220 of the support apparatus 10 when the surface assembly 26 is electrically coupled with the frame assembly 12, 180. Installing the surface assembly 26 to the frame assembly 12, 180 can include providing electrical communication or electrical coupling of the surface assembly 26 to the frame assembly 12, 180. For example, in aspects, the surface assembly 26 can include electronic control components, such as the retraction assembly 150, the pneumatic system 92, and / or the MCM layer, can be in communication with a controller 230 of the control assembly 94 of the surface assembly 26. The pneumatic system 92 generally includes a blower and air bladders for providing various therapies or assistance to a caregiver, such as a turning air bladder, an alternating pressure air bladder, a percussive air bladder, and the like.

[0091] In such examples, the electronic control components can be communicatively coupled with the controller 230 of the support apparatus 10. A first electrical connector 232 of the surface assembly 26 engages with a docking electrical connector 234 of the support apparatus 10 to provide electrical communication therebetween. Generally, the communication between the surface assembly 26 and the frame assembly 12, 180 is wired communication. However, without departing from the teachings herein, the communication can be wireless communication.

[0092] When communication is established between the surface assembly 26 and the frame assembly 12, 180, the controller 230 of the support device 10 can activate the electromagnets to couple the surface connectors 208, 210 with the mating connectors 46, 48, including the electromagnets on the surface assembly 26 and / or the upper frame 14, 184. The controller 230 includes a processor 240, a memory 242, and other control circuitry. Instructions or routines 244 are stored in the memory 242 and executable by the processor 240. The controller 230 can include communication circuitry 246 for bidirectional wired and wireless communication.

[0093] The controller 230 can activate the electromagnets in response to input by a caregiver in the user interface 220. The caregiver can position the surface assembly 26 on the upper frame 14, 184, couple the electrical connectors 232, 234, and input a command on the user interface 220 to activate the electromagnets. The user interface 220 can also be located on a remote device in wireless communication with the controller 230 without departing from the teachings herein.

[0094] Additionally or alternatively, the controller 230 can be configured to automatically activate the electromagnets based on routines 244 and can also automatically adjust the drape 156. The controller 230 can include routines 244 (e.g., software or algorithms) that automatically trigger activation of the electromagnets when electrical communication is established between the surface assembly 26 and the frame assembly 12, 180. In other words, when the electrical connectors 232 of the surface assembly 26 are connected to the electrical connectors 234 of the frame assembly 12, 180, the controller 230 can recognize the connection and trigger activation of the electromagnets. This can facilitate maximizing efficiency of the surface installation process. Moreover, this communication can allow the controller 230 to recognize and control components of the surface assembly 26, such as the MCM layer, the pneumatic system 92, the retraction assembly 150, etc.

[0095] In examples where the controller 230 is configured to control the attachment system 90 and / or the surface assembly 26 in response to input in the user interface 220 of a remote device, the controller 230 is configured to communicate with remote or external components (such as a remote device) via a wireless communication network. The communication network can be part of a medical facility network, which can include a combination of wired connections (e.g., Ethernet) and wireless connections (which can include the wireless communication network). The communication network can include various electronic devices that can be configured to communicate through various wired or wireless communication protocols. The communication network can include wireless routers through which remote access devices can communicate with each other and with local servers.

[0096] The communication network can be implemented via one or more direct or indirect non-hierarchical communication protocols, including but not limited to Bluetooth Bluetooth Low Energy (BLE), Thread, Ultra-Wide Band (UWB), Z-Wave, Zigbee, etc. Additionally, the communication network can equate to a centralized or hierarchical communication network in which one or more devices communicate via a wireless router (e.g., a communication routing controller). As such, the communication network can be implemented through various communication protocols including, but not limited to, Global System for Mobile Communications (GSM), General Packet Radio Service, Code Division Multiple Access, Enhanced Data GSM Environment, fourth generation (4G) wireless, fifth generation (5G) wireless, Wi-Fi, Worldwide Interoperability for Microwave Access (WiMAX), Local Area Network, Ethernet, etc. Through flexible implementation of the communication network, various devices and servers can directly communicate with one another via the wireless communication network or cellular data connection.

[0097] In certain aspects, the controller 230 is capable of wireless communication via a wireless communication module. The wireless communication module generally communicates with circuitry associated with the support apparatus 10 (e.g., the communication circuitry 246) via an SPI link and with a wireless access point via a wireless 802.11 link. The wireless access point is generally coupled to an Ethernet switch via an 802.3 link. It is contemplated that the wireless communication module can communicate with the wireless access point through any wireless protocol of the present disclosure. Additionally or alternatively, the Ethernet switch can generally communicate with an Ethernet network via an 802.3 link. The Ethernet network also communicates with a local server, allowing information and data to be communicated to and from the controller 230.

[0098] Still referring to Figures 1 to 17 The attachment system 90 of the present disclosure generally reduces the number of coupling components between the surface assembly 26 and the frame assembly 12, 180. In certain aspects, there can be no or very few components of the attachment system 90 between the bottom surface 114 of the outer pad 28 and the upper support surface 18. In other examples, the straps 30 extend between the support surface 18 and the bottom surface 114 of the outer pad 28. In such examples, the straps 30 are generally less than 1 millimeter in thickness and about 1 or 2 inches in width, thus not creating substantial pressure points on the patient.

[0099] Other systems generally utilize knobs to attach the mattress to the frame. The height of the knobs (extending from the surface of the frame) can create pressure points on the patient when installed improperly or not fully installed. Over time, improperly installed knobs can cause damage to the mattress, which can result in pressure sores or discomfort for the patient. Additionally, the knob components are manually attached by the caregiver.

[0100] The attachment system 90 of the present disclosure generally reduces the number of coupling components between the surface assembly 26 and the frame assembly 12, 180. In certain aspects, there can be no or very few components of the attachment system 90 between the bottom surface 114 of the outer pad 28 and the upper support surface 18. In other examples, the straps 30 extend between the support surface 18 and the bottom surface 114 of the outer pad 28. In such examples, the straps 30 are generally less than 1 millimeter in thickness and about 1 or 2 inches in width, thus not creating substantial pressure points on the patient.

[0101] Additionally, other conventional attachment designs, such as knobs, generally do not allow the mattress to move relative to the frame. As such, when the frame is moved, such as to a sit-up position, the mattress bunches up in the patient's seat region. This bunching can cause discomfort, such as causing pressure points or shear on the patient's skin. The attachment system 90 of the present disclosure utilizes the straps 30 and / or the slots 190, 192 to keep the surface assembly 26 coupled to the frame assembly 12, 180 while allowing the surface assembly 26 to slide a predefined distance.

[0102] For example, the engagement provided by the attachment system 90 facilitates movement of the upper frame 14, 184 relative to the lower frame 16, 182. As the segments 60, 62, 64 of the upper frame 14, 184 articulate relative to one another, the surface assembly 26 also moves between positions with the frame assembly 12, 180. The surface assembly 26 remains coupled to the upper frame 14, 184 to continue to support the patient and / or provide various therapies in the various positions. The surface assembly 26 can slide relative to the support surface 18 a predefined distance while remaining positioned to provide the various therapies for the patient. This sliding generally occurs in the chest region of the surface assembly 26 along the head and chest segment 60 of the upper frame 14, 184. This sliding can also occur in the foot segment 64 based on the articulation of the upper frame 14, 184.

[0103] The length of the straps 30 and the length of the slots 190, 192 allow the surface assembly 26 or a portion of the surface assembly 26 to move a predefined degree or distance as the upper frame 14, 184 articulates between positions. This movement keeps the surface assembly 26 properly positioned to the frame assembly 12, 180 and the patient to provide the various therapies and treatments. Further, the sliding can move about less than 5 inches. For example, with the attachment system 90 of the present disclosure, the surface assembly 26 can slide relative to the support surface 18 while remaining engaged between the docking connectors 46, 48 when the head end segment 60 is rotated to raise the head of bed position as compared to conventional attachment designs, thereby reducing or eliminating bunching in the seat region of the upper frame 14, 184 (e.g., in the region proximate the junction between the head segment 60 and the seat segment 62).

[0104] Further, the attachment system 90 can provide feedback to the caregiver regarding the engagement between the strap connectors 40, 42 and the docking connectors 46, 48. The feedback can be visual based on the position of the docking connectors 46, 48 and the position of the engagement between the strap connectors 40, 42 and the docking connectors 46, 48. Further, with the surface assembly 26 electrically coupled to the frame assembly 12, 180, the feedback can be provided via the user interface 220 or wirelessly communicated to a remote device.

[0105] Still referring to Figures 1 to 17In various aspects, the attachment system 90 can provide for automatic installation of the surface assembly 26 with the frame assembly 12, 180. The attachment system 90 can be configured to pull the strap 30 into engagement with the docking connector 46, 48 without requiring substantial manual movement of the strap 30 by the caregiver. In addition, the attachment system 90 can include a retraction assembly 150 to adjust the length of the strap 30 so as to properly engage the docking connector 46, 48, place the strap 30 in tension to secure the surface assembly 26, and reduce or eliminate excess length of the strap 30. Shorter straps 30 can reduce the risk of the strap 30 catching or hitting the frame assembly 12, 180. In addition, shorter straps 30 are generally used with more accessible docking connectors 46, 48, which can allow the caregiver to more easily and efficiently install and remove the surface assembly 26.

[0106] The attachment system 90 can also include positioning features of the docking connector 46, 48. These positioning features can assist the caregiver in locating the docking connector 46, 48. Such a configuration can be particularly advantageous for configurations in which the frame connector 130, 132 is disposed on the lower surface 20 of the upper frame 14, 184 or the bottom surface 114 of the outer pad 28, as the caregiver can have less visibility of the docking connector 46, 48 in such configurations. These positioning features can be visual, tactile, and / or audible features to assist the caregiver in locating the docking connector 46, 48, or the strap connector 40 in close proximity to the docking connector 46, 48 (e.g., within a predefined distance).

[0107] Additionally, while the support apparatus 10 is shown as a hospital bed, the support apparatus 10 can have various configurations such as an operating table, a stretcher, a transport bed, a MedSurg bed, etc. Each configuration of the support apparatus 10 can include the frame connector 130, 132 and / or the slot 190, 192 to allow for selective exchange of the surface assembly 26 between various types of support apparatus 10 using the attachment system 90. In addition, the surface assembly 26 can be used with different docking connectors 46, 48 or different locations of the docking connector 46, 48 on different styles and types of support apparatus 10. The attachment system 90 provides an interchangeable system of the surface assembly 26 on various support apparatus 10. The strap 30 generally extends around the side surfaces 22, 24 of the upper frame 14, 184, but additionally or alternatively can extend around the end surfaces 80, 82 depending on the configuration of the support apparatus 10.

[0108] The attachment system 90 facilitates proper installation of the surface assembly 26 and the frame assembly 12, 180 to provide a selected therapy to a patient and to align the electrical connectors 232, 234. For example, when the pneumatic system 92 is used, various air bladders are arranged in specific locations of the surface assembly 26 to provide the therapy. Proper alignment of the surface assembly 26 to the frame assembly 12, 180 allows proper alignment between the patient and the surface assembly 26. In addition, this relationship between the patient, the surface assembly 26 and the frame assembly 12, 180 remains constant as the upper frame 14, 184 is articulated between various positions, but allows for slight slippage to prevent bunching of the surface assembly 26. Proper installation of the surface assembly 26 facilitates maximum functionality of the surface assembly 26 to the patient.

[0109] Numerous advantages and benefits are provided by the disclosed apparatus. For example, the attachment system 90 maintains engagement between the surface assembly 26 and the frame assembly 12, 180. In addition, the surface assembly 26 is interchangeable with various types and configurations of support devices 10. In addition, the attachment system 90 is thin, thereby minimizing the risk of pressure ulcers to the patient and any impact on the caregiver workflow and functionality of the frame assembly 12, 180. In addition, the attachment system 90 provides flexible engagement between the surface assembly 26 and the frame assembly 12, 180, allowing the surface assembly 26 to slip as the upper frame 14, 184 is articulated to prevent bunching at the articulation of the surface assembly 26. Other benefits and advantages can be realized and / or obtained.
