Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 363,682, filed on April 27, 2022, entitled “ELECTRONIC DEVICE SECUREMENT STRAP,” the entire disclosure of which is hereby incorporated by reference into this document. Technical Field

[0003] The described embodiments generally relate to fixtures. More specifically, the embodiments relate to fixtures for wearable electronic devices. Background Art

[0004] Recent advances in portable computing have enabled head-mounted devices to provide users with augmented reality (AR) and virtual reality (VR) experiences. Various components of these devices, such as display screens, viewfinders, straps, speakers, batteries, and other components work together to provide an immersive experience. These different components add weight to the device, which must be fixed to the user's head during use. Typically, a strap, a band, an arm, or other fixing mechanism connected to the display component of the device can extend at least partially around the user's head and apply an inward force to the head to fix the display in front of the user's eyes. These straps apply enough force to press the display against the user's face, including pressing against the user's cheeks, nose, and forehead, to fix the display in front of the user's eyes and maintain this position when the user may move around or push the device during use.

[0005] During extended use, for example, when using a head-mountable device to watch a movie or play a game for several minutes or hours at a time, the forces exerted on the user's face by the securing mechanism and, thereby, the display component may become uncomfortable. The forces exerted by the device to the user, particularly the forces exerted on the front / face of the user's head and the back of the user's head (where the fastening strap or other fastening mechanism produces the force of the display component on the face), may produce uneven pressure concentrations, which may exacerbate the user's discomfort.

[0006] Therefore, what is needed in the art are apparatus and systems for securing wearable electronic devices (including head-mountable devices) to a user without causing discomfort and pain due to prolonged use. Summary of the invention

[0007] In one example of the present disclosure, a fixing strap for a head-mountable device may include a variable length strap, a first load distributing member connected to the variable length strap, and a second load distributing member connected to the first load distributing member through the variable length strap and separated from the first load distributing member. The first load distributing member and the second load distributing member may be fixed in length. The variable length strap may include an elastic material, and the first load distributing member and the second load distributing member may be rigid.

[0008] In one example, the variable length band may include a plurality of sections, wherein one section of the plurality of sections extends between the first load distributing member and the second load distributing member. In one example, the first load distributing member may include a housing defining an interior volume and a concave curved surface. In one example, the retaining band may also include electronic components disposed within the interior volume. In one example, the retaining band may also include an elastic buffer disposed on the concave curved surface. In one example, the elastic buffer may include foam. In one example, the elastic buffer may include a fluid-filled bladder. In one example, the variable length band may include an elastic material. In one example, the first load distributing member and the second load distributing member are more rigid than the variable length band.

[0009] In at least one example of the present disclosure, a head-mountable device may include a display component and a fixing strap connected to the display component. The fixing strap may include a first load distributing member, a second load distributing member, and a first elastic portion connecting the first load distributing member and the second load distributing member and separating the first load distributing member and the second load distributing member.

[0010] In one example, the first load distributing member and the second load distributing member each include a curved surface configured to conform to the head. In one example, when the user wears the head-mountable device, the first load distributing member may be configured to press against the left side of the user's head, and the second load distributing member may be configured to press against the right side of the user's head. In one example, the head-mounted device may also include a third load distributing member disposed between the first load distributing member and the second load distributing member along the length of the fixing band, and a second elastic portion connecting the second load distributing member and the third load distributing member and separating the second load distributing member and the third load distributing member. In one example, the first load distributing member may define a first concave curved surface, the second load distributing member may define a second concave curved surface, and the third load distributing member may define a third concave curved surface, the curvature of the third concave curved surface being different from the curvature of the first concave curved surface and the second concave curved surface. In one example, the third load distributing member may be configured to press against the back of the user's head when the user wears the head-mountable device.

[0011] In at least one example of the present disclosure, a load distributing member may include a body defining a concave curvature and a strap engagement feature configured to connect the load distributing member to a securing strap of a wearable electronic device.

[0012] In one example, the concave curved surface may include a curvature configured to conform to the head. In one example, the body may include a housing defining an interior volume. In one example, the load spreading member may also include electronic components disposed in the interior volume. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Reference will now be made in detail to the representative embodiments illustrated in the accompanying drawings. It should be understood that the following description is not intended to limit the embodiments to a preferred embodiment. On the contrary, it is intended to cover substitutions, modifications and equivalents that may be included within the spirit and scope of the described embodiments defined by the appended claims.

[0029] The following disclosure relates to fixtures and systems. More specifically, the following disclosure relates to fixtures for securing a wearable electronic device to a user. In one example, a wearable electronic device may include a head-mounted device, such as an AR / VR device having a display component for securing to a user's face. However, the devices and systems described herein are not limited to head-mounted devices. For example, the fixing straps and devices described herein can be used to secure any wearable device (including a wearable electronic device) to a user's body. Other devices may include a wristwatch, an armband including a fitness tracker, a medical device such as a heart rate monitor, or other devices worn by a user.

[0030] In a specific embodiment, the head-mounted display includes a display component and a fixing strap that reduces pressure concentration and distributes the pressure experienced by the user more evenly around the user's head. In one example, the fixing strap is connected to the display component and extends at least partially around the user's head to apply inward pressure to the head, thereby maintaining the position of the display component on the user's face in front of the user's eyes. Therefore, the display component, which may include a significant portion of the weight of the head-mounted device, presses against the user's cheeks, nose, and forehead with sufficient force to maintain its position during use, which may generally include the device being pushed when the user moves around or changes position. Because the display component is positioned in front of the user's head, the reaction force provided by the fixing strap is naturally concentrated on the opposite rear side of the user's head.

[0031] However, the harness of the present disclosure includes load distributing members integral with or connected to the harness that transfers load from the front and back of the user's head to the left and right sides of the user's head. In this way, the front and back of the user's head do not need to bear the entire pressure applied by the harness. In one example, the load distributing members of the harness include a body that is more rigid than other connected portions of the harness so that the forces acting inwardly on the sides of the user's head through each load distributing member are dispersed along the entire contact area between the load distributing member and the head.

[0032] In one example, the portion of the strap described herein that extends between and connects the various load distributing members is a variable length portion of the strap for adjustability. In one example, the variable length portion may include a crank or ratchet mechanism that can be adjusted by the user to customize the overall length of the strap and the position of the various load distributing members. In contrast, the load distributing members may be fixed in length and may include a rigid body as described above to distribute the load applied to the user's head. In one example, the variable length portion of the strap described herein includes a portion of elastic material that extends between and connects the various more rigid load distributing members. The elastic material may be stretched when putting on and taking off the device and provide an inward force of the strap around the head, including an inward force of the load distributing members against the head.

[0033] Additionally, as described above, a head-mountable device may include multiple electronic components that work together during use, including speakers, batteries, logic boards and circuit components, antennas, and the like. Any one or more of these components may be incorporated into a load distribution member and electrically connected to each other and / or to the display component of the device so that the weight from these components can be distributed around the user's head rather than concentrated where the display component presses against the front of the user's face. In this way, the apparatus and systems described herein may allow a user to wear a head-mountable device or other wearable electronic device for extended periods of time without pain or discomfort.

[0034] References below Figures 1 to 12BThese embodiments and other embodiments are discussed. However, those skilled in the art will readily appreciate that the detailed descriptions of these figures given herein are for illustrative purposes only and should not be construed as limiting. In addition, as used herein, a system, method, article, component, feature, or sub-feature comprising at least one of a first option, a second option, or a third option should be understood to refer to a system, method, article, component, feature, or sub-feature comprising one of each listed option (e.g., only one first option, only one second option, only one third option), a plurality of a single listed option (e.g., two or more first options), two options simultaneously (e.g., one first option and one second option), or a combination thereof (e.g., two first options and one second option).

[0035] Figure 1 A top view of a user wearing an example of a head mountable device 100 is shown, which includes a securing strap 106 securing a display assembly 104 to a head 102. The device 100 includes a variable length strap 108, a first load distributing member 110 connected to the variable length strap 108, and a second load distributing member 112 connected to and separate from the first load distributing member 110 by the variable length strap 108. In at least one example, the first load distributing member 110 and the second load distributing member 112 are rigid and / or fixed in length. The securing strap 106 may include an overall length, which represents the longitudinal length of the strap following its curvature around the head 102. In Figure 1 In the illustrated example, the strap 106 may have an overall length that includes the sum of its individual portions, including lengths D1-D4 as shown. In one example, the load distributing members 110, 112 include a fixed length that represents the length that the rigid body of the load distributing members 110, 112 extends along one side of the user's head 102. Figure 1 In the illustrated example, each load spreading member 110 , 112 may have the same length D1 . However, other examples of load spreading members described herein are not limited thereto.

[0036] In at least one example, the fixed strap 106 may include one or more variable length straps 108, one example of which has multiple sections, such as Figure 1 As shown, each segment extends between the load spreading members 110, 112, connects and thereby separates the load spreading members and is secured to the display member 104. In one example, each segment of the variable length band 108 may vary in length. Figure 1In the illustrated example, the first section of the variable length band 108 includes a first length D2, the second section of the band 108 includes a second length D3, and the third section of the band 108 includes a fourth length D4. Each of these lengths D2-D3 can be changed or adjusted by the user during use. In one example, one or more sections of the variable length band 108 may include a plurality of rigid material sections connected together via a ratchet or turntable tensioning mechanism. In one example, the variable length band 108 may include an elastic material that stretches when the user acts on it (e.g., during putting on and taking off the head-mounted device 100). The elastic material of the variable length band 108 may include an elastic polymer, a knitted fabric, or one or more other elastic materials that are configured to be used as a component that restores shape or length after deformation. In one example, the variable length band 108 is non-rigid or flexible. Conversely, the load spreading members 110 , 112 may be formed to be rigid, inflexible, and / or stiff such that the load spreading members 110 , 112 are fixed in length.

[0037] The terms "elastic", "non-rigid", or "flexible" as used herein in describing components and materials refer to components and materials that intentionally use elasticity as a functional feature. That is, an "elastic", "non-rigid", or "flexible" component or material is deformable and recovers shape, length, or original form when not acted upon, such that deformation and recovery of the component or material are useful or advantageous features of the component or material as described herein. In contrast, the terms "plastic", "rigid", or "non-flexible" used herein to describe components and materials are those components and materials whose normal function depends on maintaining shape or form under forces that deform the "elastic" or "non-rigid" components and materials in order to perform their normal functions. Although, in theory, a "plastic" material or component can be deformable to a certain extent (e.g., a negligible extent) and still recover form, the terms "plastic" or "rigid" as used herein refer to components and materials that are not intended to be plastically deformed as part of their advantageous function, but are deformable under certain conditions.

[0038] In one example, the first load spreader 110 and the second load spreader 112 include a rigid body, shape, and / or material such that the first load spreader 110 and the second load spreader 112 are more rigid than the variable length strap 108 or segments thereof. In one example, the load spreaders 110, 112 are more rigid than the elastic material of the variable length strap 108.

[0039] like Figure 1As shown in the illustrated example of FIG, when a user wears the head mountable device 100, the first load distributing member 110 can be configured to press against the left side of the user's head 102, and the second load distributing member 112 can be configured to press against the right side of the user's head 102. When the user wears the device 100, the variable length strap 108 can thus push the more rigid, fixed length load distributing members 110, 112 inward against the head 102. At least in part because the load distributing members 110, 112 are rigid, the force from the variable length strap 108 is transmitted through the load distributing members 110, 112 and distributed along the total contact area between each distributing member 110, 112 and the head 102.

[0040] In addition, for reference throughout this disclosure, Figure 1 The orientation of the user's head 102 is shown, including the front side F, the back or rear side B, the left side L, and the right side R of the head. For clarity, Figure 1 This orientation of the user's head 102 shown in FIG. 1 is similar to other figures shown and described herein when illustrating top views of the user's head 102 .

[0041] Figure 1 Any of the features, components, and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Similarly, any of the features, components, and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Figure 1 Examples of devices, features, components, and parts are shown.

[0042] Figure 2 A top view of another example of a head mountable device 200 is shown, which includes a strap 206 that secures a display component 204 to a user's head 202. The strap 206 may include separate variable length sections 208a, 208b, and 208c, which may be collectively referred to as a variable length strap 208. The first section 208a may extend between the first load distributing member 210 and the display component. The second section 208b may extend between the first load distributing member 110 and the second load distributing member 112, and the third section 208c may extend between the second load distributing member 112 and the display component 204.

[0043] Additionally, in at least one example, the first load distributing member can include a housing 214 defining an interior volume 216 and a concave exterior surface 218 that is configured to conform to the curvature of the head 202. Similarly, the second load distributing member 212 can include a housing 220 defining an interior volume 222 and a concave exterior surface 224 that conforms to the head 202 of the user.

[0044] The shape, size, material, configuration, volume of the interior volumes 216, 222, and the contour of the outer surfaces of the load distributing members 210, 212 (including the concave surfaces 218, 224, respectively) can vary from example to example. The concave surfaces 218, 224 can vary, for example, to accommodate different curvatures of different user's heads. In one or more examples, each load distributing member 210, 212 can be changed or adjusted to change the curvature of the concave surfaces 218, 224, thereby customizing the shape of each load distributing member and the fit with the user's head.

[0045] In at least one example, the position of each load spreader 210, 212 relative to the user's head or other anatomical features including the user's ears can be adjusted for a customized fit. User preferences for comfort and preferred load spreader positioning can vary. In one example, the overall length of each section 208a-208c of the variable length strap 208 can be adjusted to change the position of one or more of the load spreaders 210, 212. In one example, the rest length of each section 208a-208b of the variable length strap 208 (referring to the length that each section 208a-208b defaults to in the absence of force or change from the user) can be adjusted to change the position of each load spreader 210, 212 around the user's head 202.

[0046] The curvature of the concave surfaces 218, 224 of the load distributing members 210, 212, respectively, may be curved to match the curvature of the head where the load distributing members 210, 212 contact the head 202. In this way, the surface area contact between each load distributing member 210, 212 and the head 202 may be maximized so that the forces acting inwardly on the head 202 from the strap 206 may be evenly dispersed through the entire contact area, thereby reducing the forces felt at any one point on the head 202.

[0047] Figure 2 Any of the features, components, and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Similarly, any of the features, components, and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Figure 2 Examples of devices, features, components, and parts are shown.

[0048] Figure 3Another example of a wearable device, such as a head mountable device 300, is shown, which includes a strap 306 disposed around a user's head 302 and securing a display component 304 to the front of the user's head 302, above the eyes. The strap can connect the display component 304 and include a first load distributing member 310, a second load distributing member 312, and a third load distributing member 326. The third load distributing member 326 may include a housing 328 defining an outer concave curved surface 332 and an inner volume 330. The third load distributing member 326 may include a rigid material or structure. In at least one example, the third load distributing member 326 is fixed in shape, length, or form, and / or is more rigid than one or more elastic / variable length portions 308a, 308b, 308c, and 308d of the strap 306.

[0049] The first section 308a of the fixing strap 306 may extend between the first load distributing member 310 and the display component and connect the first load distributing member to the display component. The second section 308b of the fixing strap 306 may extend between the first load distributing member 310 and the third load distributing member 326 and connect the first load distributing member to the third load distributing member. The third section 308c of the fixing strap 308d may extend between the third load distributing member 326 and the second load distributing member 312 and connect the third load distributing member to the second load distributing member. The fourth section 308d of the fixing strap 306 may extend between the second load distributing member 312 and the display component 304 and connect the second load distributing member to the display component. Each section 308a-308d of the fixing strap 306 may be referred to as an elastic portion and may include a variable length mechanism and / or an elastic material.

[0050] The strap 306 may include various variable length sections 308a-308d that push the load spreaders 310, 312, and 326 against the left side, right side, and rear side of the head 302, respectively. Figure 3 As shown, the force applied to the user's head by the fixing belt 308 is dispersed through the total contact area between the first load distributing member 310, the second load distributing member 312 and the third load distributing member 326 and the head 302. The concave curved surface 332 defined by the shell 328 of the third load distributing member 326 can be different from the concave curved surfaces 318 and 324 of the first load distributing member 310 and the second load distributing member 312, respectively, to adapt to the curvature of the back side of the user's head 302, which can be different from the curvature of the left and right sides of the head 302.

[0051] In at least one example, the first load spreader 310 and the second load spreader 312 specifically relieve some of the pressure that would otherwise be applied to the back of the head by the third load spreader (or that area of ​​the harness 306 if the third load spreader 326 is not present) and apply it to the left and right sides of the user's head 302. In this way, the load spreaders 310, 312 can distribute the overall load so that the maximum force felt by the user from the harness 306 is reduced.

[0052] Figure 3 Any of the features, components, and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Similarly, any of the features, components, and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Figure 3 Examples of devices, features, components, and parts are shown.

[0053] Figure 4 An example of a wearable electronic device 400 secured to a user's head 402 is shown, including a head-mountable display 404 secured via a strap 406. The strap may include one or more load distributing members, including a first load distributing member 410 configured to press against the left side of the user's head 402, a second load distributing member 412 configured to press against the right side of the user's head 402, and a third load distributing member 426 configured to press against the back side of the user's head 402.

[0054] Additionally, the securing strap 406 may include a variable length strap 408 that includes a single piece or part that extends around the user's head 402 and presses each load distributing member 410, 412, and 426 against the user's head 402. In such an example, rather than multiple different sections of the strap 408, a single strap 408 may extend around the user's head 402 and connect to each load distributing member 410, 412, 426, such that the strap 408 extends between, connects to, and separates each load distributing member 410, 412, 426. Each load distributing member 410, 412, 426 may be secured to the strap 408 using one or more attachment mechanisms, including via adhesive adhesion, co-molding with the strap 408, or buttons, buckles, clamps, hook and loop mechanisms, and the like. In one example, one or more of the load distributing members 410 , 412 , 426 can be adjustably secured to the strap 408 such that each load distributing member 410 , 412 , 426 can be adjusted into position along the length of the strap 408 to accommodate various head shapes and curvatures.

[0055] Figure 4Any of the features, components, and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Similarly, any of the features, components, and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Figure 4 Examples of devices, features, components, and parts are shown.

[0056] Figure 5 Another top view of a user wearing an electronic device 500 on his or her head 502 is shown, which includes a securing strap 506 extending around the head 502 to hold the display component 504 against the user's face in front of the eyes. In the illustrated example, the securing strap 506 includes a variable length strap 508 or multiple sections thereof extending between a first load distributing member 510, a second load distributing member 512, and a third load distributing member 526, respectively. The first load distributing member 510 may include a housing 514 defining an interior volume 514. The second load distributing member 512 may include a housing 520 defining an interior volume 522. The third load distributing member 526 may include a housing 528 defining an interior volume 526.

[0057] In at least one example, one or more electronic components 534a-534f can be disposed in the interior volume 516, 522, 530 of the load spreading members 510, 512, 526. The various electronic components 534a-534f can be collectively referred to as electronic components 5334. The illustrated example shows two electronic components 534 disposed in the interior volume 516, 522, 530 of the load spreading members 510, 512, 526, but in one or more other examples, more or less than two electronic components 534 can be disposed in the load spreading members 510, 512, 526. For ease of description, reference will be made to the electronic components 534a, 534b in the interior volume 516 of the first load spreading member 510, while the same description can apply to the various electronic components 534c-534f disposed in the interior volumes 522, 530 of the second and third load spreading members 512, 516.

[0058] As described above, the first load spreading member 510 may include a housing 514 that defines an interior volume 516 in which electronic components 534a and 534b are disposed. In at least one example, the electronic components 534 may be any component configured to operate the device 100. These components 534 may include, for example, a battery, a processor, a speaker, a circuit board and components thereof, wires, an antenna, etc. The electronic components 534 may be electrically coupled to one or more components of the display component 504, including a display screen, a speaker, a light, etc. The electronic components 534 disposed in the load spreading member 510 may be electrically coupled to the display component 504 via one or more wires, wires, or other conductive paths extending from the first load spreading member 510 to the display component 504. In one example, the wires extend through the variable length band 508 to connect the electronic components 534 to the display component 504.

[0059] Additionally or alternatively, in one or more other examples, the electronic components 534 of the load spreading member 510 can be in electrical communication with the display member 504 or components thereof via wireless communication between a transmitter / receiver in the load spreading member 510 and the display member 504. These same methods of electrically coupling the electronic components 534 of the load spreading member 510 to the display member 504 can also be applied to other electronic components 534 disposed in other load spreading members 512, 526. In addition, the electronic components 534 from one load spreading member 510, 512, 526 can be electrically coupled to other electronic components 534 in other load spreading members 510, 512, 526 in a similar manner, such as wires extending through the variable length strip 508 and / or wireless communication therebetween.

[0060] In at least one example, one or more electronic components 534 of the load spreading members 510, 512, 526 can be disposed on an exterior surface or at a location different from within their interior volumes 516, 522, 530. In one example, the housings 514, 520, 528 of the load spreading members 510, 512, 526, respectively, can define one or more openings configured to allow the electronic components 534 to communicate with an external environment, such as a sensor or a speaker that transmits sound waves through the openings, a microphone that receives external sound waves through the openings, and the like.

Similarly, any of the features, components, and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Figure 5 Examples of devices, features, components, and parts are shown.

[0062] Fig. 6A and Figure 6B Another example of a wearable electronic device 600 secured to a user's head 602 is shown, including a securing strap 606 securing a display component 604 or display of the head-mountable device 600 to the head 602. The securing strap 606 may include a variable length strap 608 including segments 608a-608d extending between various load distributing members 610, 612, 626 and between the load distributing members 610, 612 and the display component 604. The variable length strap 608 applies an inward force to push the load distributing members 610, 612, 626 inward toward the head 602 to secure the device 600 to the head. As shown, the first load distributing member 610 applies a first force 636 inward on the left side of the head 602 to counteract a second force 638 from the second load distributing member 612 acting on the right side of the head 602. The third load distributing member 626 can generate a third inward force 640 on the head to counteract the force from the display member 604 on the front side of the head 602 .

[0063] The magnitude of each of these forces 636, 638, 640 from the load spreaders 610, 612, 626 may vary, but in Fig. 6A 636, 638, 640 are shown as being substantially similar in magnitude, as indicated by the length of the reference arrow. The forces 636, 638, 640 are not limited in this regard, but are shown in this manner for purposes of explanation and are not intended to be confused with the forces 636, 638, 640 of FIG. Figure 6B The magnitudes of the different forces shown in the figure are compared. Fig. 6A , the belt angle β extending outward from the third load distributing member 626 disposed against the back side of the user's head 602 describes the angle at which the belt segments 608a and 608c extend away from the third load distributing member 626. The two opposing belt angles β are shown as being the same or similar in magnitude, but may be different in one or more other examples. As the belt angle β decreases, the force 640 exerted on the back of the user's head 602 also decreases based on the vector direction of the belt segments 608b and 608c extending from the third load distributing member 626, and vice versa.

[0064] Fig. 6A Also shown are strap angles α, which represent the angles at which strap segments 608a and 608d extend away from display member 604. Again, these strap angles α are shown to be the same or similar from the left side to the right side of head 602, but may be different in one or more other examples. As strap angles α decrease, the force applied to the user's face from display member 604 on the front of head 602 decreases, and vice versa.

[0065] The size or shape of the first load distributing member 610 and the second load distributing member 612 that exert pressure on the left and right sides of the user's head 602, respectively, at least partially determines the belt angles α and β. Therefore, in one or more examples, the first load distributing member 610 and the second load distributing member 612 can be configured to reduce the belt angles α and β and transfer some of the pressure (including the force 640) exerted on the front and back of the head 602 to the left and right sides of the head 602. Figure 6B This concept is shown where the first load spreader 610 and the second load spreader 612 are larger or further laterally extended away from the head 602 to reduce the belt angles α and β. As shown, this increases the first force 636 and the second force 638 on the side of the head 602 while reducing the third force 640 from the third load spreader 626 and thereby reducing the opposing force on the front side or face of the head 602 from the display component 604 positioned opposite the third load spreader 626.

[0066] Therefore, the size, shape, location and configuration of each load distributing member 610, 612, 626 can be designed to transfer and redistribute the force from the fixing strap 606 acting on the user's head 602. In particular, the first load distributing member 610 and the second load distributing member 612 can be configured to relieve the pressure and force from the display component of the wearable device 600 acting on the front of the user's head 602 and face, so that the user can wear the device 600 for a long time while minimizing or eliminating discomfort and pain.

Similarly, any of the features, components, and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. FIG. 6A to FIG. 6B Examples of devices, features, components, and parts are shown.

[0068] Figure 7 Another example of a wearable electronic device 700 secured to a user's head 702 is shown, including a securing strap 706 securing a display member 704 or display of the head-mountable device 700 to the head 702. The securing strap 706 may include a variable length strap 708 including sections extending between various load distributing members 710, 712, 726 and between the load distributing members 710, 712 and the display member 704. The variable length strap 708 applies an inward force to push the load distributing members 710, 712, 726 inward toward the head 702 to secure the device 700 to the head.

[0069] In at least one example, one or more of each load distributing member 710, 712, 726 can have an elastic cushioning member 742 disposed on an outer concave surface between the load distributing member 710, 712, 726 and the head 702. The elastic cushioning member can include, for example, a foam material and / or a fluid-filled bladder that can disperse any pressure concentrations that occur due to the change in curvature of the user's head 702 with the curvature of the rigid load distributing member 710, 712, 726. One or more other elastic or cushioning materials or configurations can also be included in the embodiment of the present invention. Figure 7 In the buffer member 742 shown.

Similarly, any of the features, components, and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Figure 7 Examples of devices, features, components, and parts are shown.

[0071] Figure 8 A front cross-sectional view of a user's head 802 is shown with a first load distributing member 810 and a second load distributing member 812 pressed against the sides of the head 802 by a strap 808. In the illustrated example, the load distributing members 810, 812 can include features that push the load distributing members 810, 812 upward and prevent the load distributing members 810, 812 from sliding downward over time as gravity counteracts the friction forces holding the device on the user's head 802. In at least one example, as Figure 8 As shown, these upward push features may include directional teeth or protrusions. In one or more other examples, these features may include a high friction material or coating on the inner surface of the load spreading members 810, 812.

[0072] Figure 8 Any of the features, components, and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Similarly, any of the features, components, and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Figure 8 Examples of devices, features, components, and parts are shown.

[0073] Fig. 9A front cross-sectional view of a user's head 902 is shown with a first load spreader 910 and a second load spreader 912 pressed against the sides of the head 902 by the strap 908. In the illustrated example, the load spreaders 910, 912 may be shaped so that a biasing force from the variable length strap 908 or a biasing force from tightening the variable length strap 908 pushes the load spreaders 910, 912 upward to counteract the force of gravity that over time pulls downward on the load spreaders 910, 912 and the strap 908. In the illustrated example, the outer surfaces of the load spreaders 910, 912 are angled so that the force vector from the strap 908 includes a vertical component 944 that pushes the load spreaders 910, 912 upward.

[0074] Fig. 9 Any of the features, components, and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Similarly, any of the features, components, and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Fig. 9 Examples of devices, features, components, and parts are shown.

[0075] Fig.10 An example of a head mountable device 1000 is shown that includes a display member 1004 secured to a user's head 1002 via a securing strap 1008. The securing strap may include a load distributing member 1012 similar to other load distributing members described with reference to other figures. In the illustrated example, the load distributing member 1012 is configured to distribute the load to the right side of the user's head 1002 when the display member 1004 is secured in front of the user's eyes. In the illustrated example, the display member 1004 may be secured to the securing strap 1008 via a connecting member 1046. The connecting member may extend from the securing strap 1008 to the display member 1004 so that the securing strap 1008 is not directly connected to the display member 1004.

[0076] Thus, in at least one example, the strap 1008 can extend completely around the user's head 1002, such as 360 degrees around the user's head, thereby providing space to position a load distributing member on any contact area around the head. In the illustrated example, the load distributing member 1012 is positioned on the side of the user's head 1002. In one example, the load distributing member can be positioned on the front of the strap 1008 and configured to press against the front side of the user's head in addition to the force applied by the display component 1004 on the user's face. In one example, the strap 1008 can also include a load distributing member on the back side in addition to the left and right sides and the front. In Fig.10In the illustrated example, a strap 1008 extending completely around the user's head can provide locations for load spreaders around the front and any points of the head to further disperse and distribute the total load applied to the user's head by the display component 1004 and the strap 1008.

[0077] Any of the features, components, and / or parts shown in FIG. 70 (including their arrangements and configurations) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Similarly, any of the features, components, and / or parts shown or described with reference to other figures (including their arrangements and configurations) may be included alone or in any combination in Fig.10 Examples of devices, features, components, and parts are shown.

[0078] Fig.11A and Fig. 11B A perspective view and a front view, respectively, of an example of a load distributing member 1110 are shown. In at least one example, the load distributing member 1110 includes a body 1148 defining an outer concave surface 1118 configured to conform to a user's head, and a strap engagement feature 1150 configured to connect the load distributing member to a securing strap of a wearable electronic device, such as a head-mountable device. As shown, the strap engagement feature 1150 can be positioned on either end of the load distributing member 1110, and the strap segments 1108a, 1108b can be connected to the corresponding strap engagement features 1150a, 1150b, as shown. Fig. 11B shown in top view.

[0079] The load distributing member 1110 and the strap 1108 can be connected as shown in any other examples of load distributing members and variable length straps shown and described with reference to other figures, so that the variable length strap segments 1108a, 1108b extend between various load distributing members and / or between the load distributing member and the display component and separate the various load distributing members and / or the load distributing member from the display component. In at least one example, the strap 1108 can be removably connected to the strap engagement features 1150a, 1150b so that the user can replace the strap 1108 or the strap segments 1108a, 1108b as needed. The strap engagement features 1150 can include mechanical connectors, including buttons, buckles, hooks, etc. In one example, the strap engagement features 1150 can include magnetic components located in the load distributing member and / or the strap 1108 to magnetically couple the strap 1108 to the load distributing member 1150.

[0080] FIG. 11A to FIG. 11BAny of the features, components, and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. Similarly, any of the features, components, and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts shown in other figures described herein. FIG. 11A to FIG. 11B Examples of devices, features, components, and parts are shown.

[0081] Fig. 12A A perspective view of an example of a load distributing member 1210 is shown, the load distributing member including a body 1248 defining a concave curved surface 1218 configured to be pressed against a user's head, and a strap engagement feature 1250 defined by a side of the load distributing member 1210 opposite the concave curved surface 1218. In the example shown, the strap engagement feature 1250 includes a channel or groove formed in or defined by the body 1248 that is configured to receive a variable length securing strap of a head mountable device.

[0082] Fig. 12B Another perspective view of the load distributing member 1210 is shown, wherein a portion of the variable length retaining strap 1208 extends through the gripper and is partially inserted or received into the strap engagement feature 1250. The variable length strap 1208 can be removably secured within the strap engagement feature 1250 of the load distributing member 1210 such that up and down displacement of the variable length retaining strap 1208 is limited by the edges or sidewalls of the recess of the strap engagement feature 1250. In this way, the variable length retaining strap 1208 can rest within the strap engagement feature 1250 and press the load distributing member 1210 (including its concave curved surface 1218) against the user's head. The load distributing member 1250 can include other strap engagement features that lock, clamp or engage the variable length strap 1208 to secure the variable length strap 1208 within the strap engagement feature 1250 during use. The load distributing member 1210 can be replaced with another load distributing member of other sizes, shapes or configurations to better accommodate a unique user.
