Description

Background Technology

[0001] Buckles are typically used to releasably connect the ends of flexible lengths, such as straps, bands, ropes, cords, and cables. In some cases, buckles can be used to releasably connect the ends of a single flexible length to form a loop, for example, for use in belts, seat belts, or the like. In other cases, buckles can be used to releasably connect the ends of different flexible lengths to form a longer overall flexible length. Many buckle design goals may be contradictory. On the one hand, it is desirable for buckles to be quickly and easily attached to and detached from the ends. On the other hand, buckles should reliably and securely connect the ends and minimize the possibility of accidental breakage. Attached Figure Description

[0038] In all the accompanying drawings, the same reference numerals denote similar but not necessarily identical elements. The drawings are not necessarily drawn to scale, and the dimensions of some parts may be exaggerated to more clearly illustrate the examples shown. Furthermore, the drawings provide examples and / or embodiments consistent with the specification; however, the specification is not limited to the examples and / or embodiments provided in the drawings. Specific Implementation

[0039] This application discloses several example buckles designed to achieve the following competing objectives: (1) providing quick, easy, and intuitive connection and disconnection; and (2) providing a secure and stable connection that is not easily broken. The example buckles achieve these objectives using a one-piece, single-unit buckle, which can be made from a single, integral body or from multiple body parts connected together, wherein relying on additional independent components for secure connection is optional. The example buckles can be used in various applications, such as seat belts, waist belts, etc.

[0040] The example buckle includes a body having a top surface, a bottom surface, a first longitudinal end, and a second longitudinal end. Two openings are formed on the body, and a rod separates the two openings and extends between them. The rod is configured for connecting a system, wherein the rod is connected to an end of a flexible length. For the purposes of this disclosure, "flexible length" can refer to a flexible strap, strip, rope, cable, or other flexible line. In some embodiments, the end of the flexible length may wrap around or be secured to itself by stitching, welding, adhesive, or the like. In some embodiments, the end of the flexible length may include additional connecting members, such as a hook releasably connected to the rod, or a fastener clamped around or otherwise connected to the rod. The flexible length extends from the rod (or from its connector) along the bottom surface of the buckle toward and then away from the first longitudinal end of the buckle.

[0041] The buckle connection system also includes a flexible length with a flexible ring. The flexible ring is sized so that the entire buckle can pass through it. In some embodiments, different portions of the ring gradually bend or deform as the buckle passes through it. In some embodiments, the ring can be elastic, meaning it can elastically stretch upon receiving the buckle. The relative shapes and sizes of the buckle and the ring ensure that once the buckle passes through the ring, they are interconnected and prevent the buckle from accidentally pulling out or breaking off, especially when tightened. In some embodiments, the flexible length with the flexible ring is the same as the flexible length of the bar connected to the buckle. In other embodiments, a first flexible length provides the flexible ring, while a separate and distinct flexible length is connected to the bar of the buckle.

[0042] In some embodiments, the first longitudinal end has a first lateral width, and the second longitudinal end has a second lateral width greater than the first lateral width. In some embodiments, the side of the buckle may taper linearly from the wider second longitudinal end to the narrower first longitudinal end. In some embodiments, the first longitudinal end may be pointed. In some embodiments, the first longitudinal end may be rounded. In some embodiments, the second longitudinal end may be flat or straight, parallel to the bar. In some embodiments, the second longitudinal end may be convex, polygonal, or concave.

[0043] The narrower width of the first longitudinal end facilitates easier slippage of the loop, making it easier to connect and disconnect. Furthermore, the narrower width of the first longitudinal end provides a visual cue indicating which end of the buckle the loop will initially connect to. The wider width of the second longitudinal end overlaps more with the loop below it than the narrower first longitudinal end, reducing the likelihood of the buckle accidentally slipping through the loop and breaking off.

[0044] In some embodiments, the buckle includes a retainer in the form of a retaining arm on its bottom or underside (the end of the flexible length extending from the bar along the same bottom surface of the buckle). The position and size of the retaining arm form a central open channel in which the flexible ring and / or portions of the flexible length constituting the flexible ring can be positioned. Once the flexible ring or portions of the associated flexible length are inserted into the channel formed by the retaining arm, the retaining arm engages with the ring and / or the flexible length, thereby retaining the ring or flexible length within the channel to prevent it from being pulled out of the channel. Thus, the flexible ring and portions of the associated flexible length are held within the channel against the bottom surface of the buckle to prevent the ring from moving away from the buckle and to prevent the buckle from accidentally looping back through the ring. The retaining arm further inhibits accidental rotation of the ring relative to the buckle (e.g., when the buckle and ring are not tensioned) to hold the closed end of the ring along a first longitudinal end and around the buckle.

[0045] In some embodiments, the retaining arm may include a pair of rods extending longitudinally on two lateral sides of the bottom surface of the buckle. In some embodiments, the retaining arm is positioned at a second longitudinal end of the buckle. In other embodiments, the retaining arm extends along the bottom surface of the buckle, extending, if not all, but almost the entire longitudinal length of the buckle, thereby forming a longitudinal channel for receiving and retaining portions of the flexible ring. In some embodiments, the retaining arm includes inwardly extending portions forming snaps or hooks that form the bottom of the channel, wherein the bottom surface of the body opposite the hook forms the top of the channel and extends along the top surface of the ring, and wherein the hook extends along the bottom surface of the ring.

[0046] In some embodiments, the retainer may take the form of a single-sided clamp. This clamp extends downwards across the underside of the buckle body. The clamp may be resilient. In such embodiments, the ring and / or the flexible length associated with the ring can slide into a channel formed by the clamp.

[0047] In some embodiments, the buckle body is flat or planar. In some embodiments, the buckle body is shaped such that the bottom surface of the buckle is concave. The concave shape of the bottom surface of the buckle can extend from a first opening to a second longitudinal end. This concave shape can form a laterally extending cavity that can receive portions of the ring, thereby further assisting in maintaining the connection between the ring and the buckle.

[0048] In some embodiments, the bottom side of the buckle may include a pair of retaining or guiding rails. These rails form a vertical channel for receiving the ring and / or the flexible length associated with the ring therein. These rails prevent accidental separation of the ring from the buckle.

[0049] In some embodiments, the first longitudinal end of the buckle includes a vertical wall extending downward from the bottom surface of the buckle. The vertical wall provides a vertical surface facing the second longitudinal end of the buckle. In some embodiments, the vertical wall may be perpendicular to the plane of the buckle or the top surface of the flexible length. In other embodiments, the vertical wall may be angled or inclined downward relative to the plane of the buckle or the top surface of the flexible length. In some embodiments, the vertical wall may extend from a first lateral side or edge to a second lateral side or edge. In some embodiments, the vertical wall may extend only a portion of the total lateral width of the buckle.

[0050] The vertical wall helps to prevent the flexible ring from moving toward and out of its range toward the first longitudinal end of the buckle, thereby helping to hold the ring around the buckle. After the buckle passes through the ring, the closed end of the ring can be clamped between the top surface of the end of the flexible length connected to the rod and the bottom surface of the buckle, and the closed end of the ring is further clamped between the upwardly curved portion of the top surface of the end of the flexible length connected to the rod and the vertical wall. The vertical wall can act as a front hook, around which the closed end of the ring can be initially fixed, thereby further facilitating the looping, securing, and fastening of the ring onto the buckle.

[0051] For the purposes of this disclosure, the term "coupled" refers to two components being directly or indirectly connected to each other. Such a connection can be fixed or movable. This connection can be achieved by integrally forming two components, or the two components with any additional intermediate component, or by interconnecting the two components or the two components with any additional intermediate component. Such a connection can be permanent, detachable, or releasable.

[0052] For the purposes of this disclosure, the phrase “configured as” indicates the actual state of configuration that fundamentally links the function / purpose to the physical characteristics of the feature preceding the phrase “configured as”.

[0053] For the purposes of this disclosure, the terms “releasable” or “detachable” in relation to the attachment or coupling of two structures mean that the two structures can be repeatedly connected and disconnected from each other without causing material damage to either of the two structures or their function.

[0054] Figures 1-5 An example connection system 20 is shown, which includes an example buckle 24, a first end 26 having a flexible length 28, and a second end 30 having a flexible length 28 or a different flexible length, wherein the second end 30 includes a ring 32. Figure 1The connection system 20 is shown in a disconnected state. Figure 2 and Figure 3 The diagram shows how ends 26 and 30 are connected by operating buckle 24 and ring 32. Figure 4 and Figure 5 The connection system 20 in a connected state is shown.

[0055] like Figure 1 As shown, the buckle 24 includes a body 34, which has a top surface 36 and a bottom surface 38 (as shown). Figure 5 (As shown), a first longitudinal end 40 and a second longitudinal end 42. Two openings 44 and 46 are formed in the body 34, and a rod 48 separates the two openings and extends between them. The rod 48 is connected to the end 26 of a flexible length member, or flexible length 28. In the illustrated example, the end 26 of the flexible length 28 is wrapped or wrapped around the rod 48 and then reattached to itself by stitching, adhesive, or similar means. In other embodiments, the end 26 of the flexible length 28 may include additional connecting members, such as a hook releasably connected to the rod 48, or a fastener clamping or otherwise connecting to the rod 48. The flexible length 28 extends from the rod 48 (or from its connector) along the bottom surface 38 of the buckle 24 toward and then away from the first longitudinal end 40 of the buckle 24.

[0056] The flexible ring 32 is sized such that the entire buckle 24 can pass through it. In some embodiments, allowing the buckle 24 to pass through the ring 32 may involve different portions of the ring gradually bending or deforming upon receiving the buckle 24. In some embodiments, the ring 32 may be elastic, wherein the ring 32 can elastically stretch upon receiving the buckle. Figure 4 and Figure 5 As shown, the relative shapes and sizes of the buckle 24 and the ring 32 are such that once the buckle 24 passes through the ring 32, the buckle 24 and the ring 32 are connected to each other, and can prevent the buckle 24 from accidentally pulling out or breaking from the ring 32, especially when tightened. In some embodiments, the flexible length of the flexible ring 32 is the same as the flexible length of the rod connected to the buckle 24. In other embodiments, the first flexible length of the flexible ring 32 is separate from and different from the flexible length 28 of the rod 48 connected to the buckle 24.

[0057] like Figure 1As shown, the first longitudinal end 40 has a first lateral width W1, and the second longitudinal end 42 has a second lateral width W2 greater than the first lateral width W1. In the illustrated example, the side of the buckle 24 tapers linearly from the wider second longitudinal end 42 to the narrower first longitudinal end 40. In other embodiments, the first longitudinal end 40 may be pointed. In other embodiments, the first longitudinal end 40 may be rounded. In the illustrated example, the second longitudinal end 42 is flat or straight and parallel to the rod 48. In other embodiments, the second longitudinal end 42 may be convex, polygonal, or concave.

[0058] The narrower width of the first longitudinal end 40 facilitates easier slippage of the ring 32 over it, making connection and disconnection easier. Furthermore, the narrower width of the first longitudinal end 40 provides a visual cue indicating which end of the buckle 24 the ring 32 will initially receive. The wider width of the second longitudinal end 42 overlaps more with the ring 32 being connected from below than the narrower first longitudinal end 40, thereby reducing the likelihood of the buckle accidentally slipping through and disconnecting from the ring 32.

[0059] Figures 2-5 The connection method between ring 32 and buckle 24 is shown. For example... Figure 2 As shown, the closed end 49 of ring 32 is positioned above end 40 (as indicated by arrow 54). Figure 3 As shown, once the end 40 passes through the opening 56 of the ring 32, the ring 32 can move away from the end 40 (as shown by arrow 57), and the end 42 can be lifted through the opening 56 as shown by arrow 58. It should be understood that the relative movement of the buckle 24 and the ring 32 can be achieved in various different ways. Ultimately, the buckle 24 completely passes through the opening 56 and enters... Figure 4 and Figure 5 The connection status is shown.

[0060] like Figure 4 and Figure 5 As shown, in the connected state, ring 32 is completely below buckle 24. Figure 5 As shown, the closed end 49 of the ring 32 is sandwiched between the top surface of the end 26 of the flexible length 28 and the lower side or bottom surface 38 of the buckle 24. To actuate the system 20 to the open state, the closed end 49 moves forward (…). Figure 4 (left side of the middle), and shaped such that the closed end 49 of the ring 32 can be lifted beyond the end 40 to allow the buckle 24 to move to the left side (as shown in the image). Figure 4 As shown), thereby pulling the buckle 24 (usually with) out of the opening 56 of the ring 32. Figure 2 and Figure 3 (The opposite of what is shown).

[0061] In the example shown, buckle 24 is integrally molded, becoming part of a single monolithic body. For example, buckle 24 can be molded as a single piece or part from one or more polymers, metals, fiber composites, ceramics, or combinations thereof, without any fasteners, welding, bonding, or other mechanical or chemical connections. In other embodiments, buckle 24 can be made from multiple interconnected components. For example, in addition to rod 48, buckle 24 can be molded or otherwise formed as a single piece, wherein rod 48 comprises a separate bar or other component that is secured in place and attached to the molded body of buckle 24. In other embodiments, the outer contour of buckle 24 can have shapes other than the trapezoid shown.

[0062] Figures 6-11 The following are shown parts of an example connection system 120, which includes an example buckle 124, a first end 26 having a flexible length 28, and a second end 30 having a flexible length 28 or a different flexible length, wherein the second end includes a loop 32. Figure 6 The connection system 120 is shown in a disconnected state. Figure 7 and Figure 8 It is shown that the ends 26 and 30 are connected by operating the buckle 124 and the ring 32. Figures 9-11 The connection system 120 in a connected state is shown.

[0063] Buckle 124 is similar to buckle 24, except that the end 140 of buckle 24 is not narrower than the end 142. Furthermore, buckle 124 also includes a retainer 158. The remaining components in buckle 124 corresponding to those in buckle 24 are referred to with similar reference numerals. In other embodiments, end 140 may also be narrower than end 142 to achieve the advantages described above regarding buckle 24. Buckle 124 may employ... Figure 1 The shape shown.

[0064] The retainer 158 is configured to extend at least partially along the bottom surface and / or a portion of the flexible length associated with the ring 32 to retain and secure the ring 32 to the buckle 124. In the illustrated example, the retainer 158 includes a pair of opposing retaining arms 160-1 and 160-2 (collectively referred to as arms 160). The retaining arms 160 project downward from the bottom surface 38 of the buckle 124 and are configured to contact or engage the ring 32 to inhibit lateral outward movement of portions of the ring 32 relative to the buckle 24. In the illustrated example, the retaining arms 160 are in the form of inwardly projecting tabs or hooks to further inhibit downward movement of the ring 32 away from the bottom surface 38 of the buckle 124. Figure 11As shown, retaining arm 160-1 extends on the first lateral side of body 134 at the second longitudinal end 142, and the first retaining arm 160-1 extends downward and inward toward the second lateral side of body. Retaining arm 160-2 extends on the second lateral side of body 134 at the second longitudinal end 142, and the second retaining arm 160-2 extends downward and inward toward the first lateral side of body.

[0065] like Figure 7 and Figure 8 As shown, ring 32 and buckle 124 move to Figures 9-11 The connection status shown is Figure 2 and Figure 3 The movement shown is similar, except that moving to a connected state may also involve... Figure 8 The movement is shown. (As indicated) Figure 8 As shown, once the body 134 of the buckle 124 passes through the opening 56 of the ring 32, the connecting portions of the ring 32 and / or the flexible length 28 are lifted (as indicated by arrow 163) and moved or bent inward to position the portions of the ring 32 and / or the flexible length 28 within the bottom opening channel 166 formed by the bottom surface 38 of the buckle 124 and the retaining arm 160, thereby preventing them from being pulled out or falling off from the channel 166. Thus, the flexible ring and / or the portions of the associated flexible length are held within the channel 166 against the bottom surface 38 of the buckle 124 to resist movement of the ring 32 away from the buckle 124 and to prevent the buckle 124 from accidentally re-threading back through the ring 32. The retaining arm 160 further prevents accidental rotation of the ring 32 relative to the buckle 124 (e.g., when the buckle 124 and the ring 32 are not tightened) to hold the closed end 49 of the ring 32 along the first longitudinal end 140 and around the buckle 124. The inwardly extending protrusions 170 of the arm 160 form latches or hooks that form the bottom of the channel 166, wherein the bottom surface 38 of the body 134 opposite to the hook forms the top of the channel 166, and wherein the hooks or inwardly extending protrusions 170 extend along the bottom surface of the ring 32 and form the bottom of the channel 166. In some embodiments, the inwardly extending protrusions 170 may be omitted.

[0066] Figures 12-17 The various parts of the example connection system 220 are shown. Figure 12 The connection system 220 is shown in a disconnected state. Figure 13 and Figure 14 The process of connecting the ends 26 and 30 by operating the buckle 224 and the ring 32 is shown. Figures 14-17The connection system 120 in a connected state is shown. System 220 is similar to system 120, except that system 220 includes a buckle 224 with a different shaped body 234, and in addition to the aforementioned retaining arms 160-1 and 160-2, it also includes retaining guide rails 262-1 and 262-2. The remaining components in system 220 corresponding to those in system 120 are given similar reference numerals.

[0067] Similar to the body 34 of buckle 24, the body 234 of buckle 224 includes a narrower end 240 and a wider longitudinal end 242. The end 240 is narrowed (in the lateral direction) by rounding or bending and has a convex front edge facing away from the end 242.

[0068] End 242 has a concave rear edge facing away from end 240. This provides a visual cue to the convex and concave front and rear edges to indicate which end of body 234 should initially be placed for connection of the opening 56 of ring 32. In other embodiments, end 242 may have a straight edge or a convex edge. In other embodiments, the curvature (radius) of ends 240 and 242 may be greater than or less than the curvature (radius) illustrated. In other embodiments, body 234 may have a similar shape to... Figure 1 The shape shown, or other shapes as described above with respect to body 34.

[0069] Retaining rails 262 protrude downwards from the lower surface or bottom surface 38 of the body 234, near or adjacent to two opposite lateral sides of the body 234. In the illustrated example, each rail 262 protrudes further from the bottom surface 38 by a distance greater than or equal to the thickness of the strip or other line forming the ring 32. The retaining rails 262 are configured to form a longitudinal channel for receiving the ring 32 when it is secured to the buckle 224. The retaining rails 262 help retain the ring 32 in the connected state by preventing lateral movement of the ring 32 during connection. While each retaining rail 262 is illustrated as a single, elongated, downwardly projecting rod extending over most (if not all) of the longitudinal length of the body 234, in other embodiments, the retaining rails 262 may have a shorter length or may be configured as a row of multiple spaced-apart, independent segments. While each retaining rail 262 shown in the figure has a uniform height along its length, in other embodiments, the height of these retaining rails 262 may vary along its length. For example, each retaining arm may have a greater height near its end 240. In some other embodiments, the height of each retaining rail 262 near the end 242 may be relatively large. It should be understood that the retaining rail 262 can also be added to any other example buckle described above or below. In some embodiments, the retaining rail 262 may be omitted.

[0070] like Figure 13 and Figure 14 As shown, ring 32 and buckle 224 move to Figures 14-17 The connection status shown is Figure 2 and Figure 3 The movement shown is similar, except that moving to a connected state may also involve... Figure 14 The movement is shown. (As indicated) Figure 14 As shown, once the body 234 of the buckle 224 passes through the opening 56 of the ring 32, the connecting portion of the ring 32 and / or the flexible length 28 is positioned between the retaining rails 262 and further lifted (as indicated by arrow 263) and moved or bent inward, thereby positioning the portions of the ring 32 and / or the flexible length 28 within the bottom opening channel 166 formed by the bottom surface 38 of the buckle 124 and the retaining arm 160, thus preventing them from being pulled out of the channel 166. Therefore, the portions of the flexible ring and / or the associated flexible length are held within the channel 166 against the bottom surface 38 of the buckle 124 to prevent the ring 32 from moving away from the buckle 124 and to prevent the buckle 224 from accidentally re-threading through the ring 32. The retaining arm 160 and guide rail 262 further suppress accidental rotation of the ring 32 relative to the buckle 124 (e.g., when the buckle 124 and ring 32 are not tightened) to hold the closed end 49 of the ring 32 along the first longitudinal end 140 and around the buckle 224. Inwardly extending protrusions 170 of the arm 160 form latches or hooks that form the bottom of the channel 166, wherein the bottom surface 38 of the body 134 opposite the hook forms the top of the channel 166, and wherein the hook or inwardly extending protrusion 170 extends along the bottom surface of the ring 32 and forms the bottom of the channel 166. In some embodiments, the inwardly extending protrusion 170 may be omitted.

[0071] Figures 18-22 The various parts of the example connection system 320 are shown. Figure 18 The connection system 320 is shown in a disconnected state. Figure 19 and Figure 20 The process of connecting the ends 26 and 30 by operating the buckle 324 and the ring 32 is shown. Figures 20-22 A connection system 320 in a connected state is shown. System 320 is similar to system 120 described above, except that system 320 includes a buckle 324 with a different shaped body 334, and includes a retainer 358 in place of retainer 158. The remaining components in system 320 corresponding to those in system 120 are referred to with similar reference numerals.

[0072] The body 234 is similar to the body 134 of the buckle 124 described above, except that the body 234 is widest at its longitudinal midpoint and narrower at its two opposite longitudinal ends. In the example shown, the body 334 is rhomboid in shape. The two tips of the body 334 facilitate easier separation of the ring 32 from the buckle 324 from both ends. The wider middle portion helps to prevent the buckle 324 from accidentally pulling out of the ring 32. In the example shown, the retainer 358 is located near the widest part of the body 334, close to or at the longitudinal midpoint of the body 334, to enhance the fixation and retention of the ring 32 after it is positioned around and below the body 334.

[0073] Compared to a retainer 158 that includes a pair of inwardly extending forks or tabs to form channel 166, retainer 358 is in the form of a single clamp 360 that hangs from the bottom surface 38 of body 334. In the illustrated example, the clamp serving as retainer 158 extends from one lateral side and across the entire body 334 so as to be positioned below both sides of ring 32 (opposite sides of opening 56). In other embodiments, the clamp 360 serving as retainer 158 may be shorter.

[0074] like Figure 22 As shown, in the illustrated example, clamp 360 forms a channel 366 with a single-sided opening 367. In the illustrated example, clamp 360 also includes a snap or lip 369 extending upward along the opening to help retain ring 32 within channel 366. In some embodiments, the size and forming material of clamp 360 cause clamp 360 to have a resilient flexibility or bendability at its connecting end 373 and / or along the length of the arm 375 forming clamp 360, to further facilitate opening the opening 367 and inserting ring 32. While clamp 360 is shown centrally located between the two longitudinal ends (the widest part of body 334) of body 334, in other embodiments, clamp 360 may be positioned at other locations on body 334. Furthermore, retainer 358 may be used in place of retainer 158 in any of the above embodiments, or as described below. Figures 23-36 The retainer in the described embodiments. In these embodiments, the retainer 358 may extend across the respective body at or near the widest point along the longitudinal length of the respective body. For example, the retainer 358 (clamp 360) may be disposed on the underside or bottom surface of the buckle, at or near the longitudinal end 142 of each of the buckles 24, 124 and 224 described above.

[0075] like Figure 19 and Figure 20 As shown, the ring 32 is secured to the buckle 324 in a manner similar to that described above regarding the buckle 124. As mentioned above, once the buckle 324 passes through the opening 56 of the ring 32 (as shown...), Figure 19As shown), the portions of ring 32 and / or the associated flexible length 28 are lifted (as indicated by arrow 363) and manipulated (simultaneously / at once or gradually, inserting the left side of the flexible length and then the right side of the flexible length) to position the portions of ring 32 and / or the associated flexible length within the channel 166 formed by clamp 360.

[0076] Figures 23-29 An example buckle 424 is shown, used as an example connection system 420 (such as...). Figures 30-36 (as shown) is a part of the buckle 424. The buckle 424 includes a body 434 having a top surface 436 (as shown). Figure 27 As shown), bottom surface 438 (as shown) Figure 26 (As shown), a first longitudinal end 440 and a second longitudinal end 442. Two openings 444 and 446 are formed in the body 434, and a rod 448 separates the two openings and extends between them. Figure 32 As shown, the rod 448 is connected to the end 26 of the flexible length 28. In the illustrated example, the end 26 of the flexible length 28 is wrapped or encircled around the rod 48 and then attached to itself by stitching, adhesive, or similar means. In other embodiments, the end 26 of the flexible length 28 may include additional connecting members, such as a hook releasably attached to the rod 448, or a fastener clamping or otherwise attached to the rod 48. The flexible length 28 extends from the rod 448 (or from its connector) along the bottom surface 438 of the buckle 424 toward and then away from the first longitudinal end 440 of the buckle 424.

[0077] The flexible ring 32 of the connecting system 420 is similar to the flexible rings of the connecting systems 20, 120, 220, and 320 described above. The flexible ring 32 is sized so that the entire buckle 424 can pass through it. In some embodiments, the buckle 424 passing through the flexible ring 32 involves different portions of the flexible ring gradually bending or deforming upon receiving the buckle 424. In some embodiments, the flexible ring 32 can be elastic, meaning that the flexible ring 32 can elastically stretch upon receiving the buckle. Figure 33 As shown, the relative shapes and sizes of the buckle 424 and the ring 32 ensure that once the buckle 424 passes through the ring 32, the buckle 424 and the ring 32 are connected to each other, and prevent the buckle 424 from accidentally pulling out and breaking off from the ring 32, especially when tightened. In some embodiments, the flexible length of the flexible ring 32 is the same as the flexible length of the rod 448 connected to the buckle 424. In other embodiments, the first flexible length of the flexible ring 32 is separate from and different from the flexible length 28 of the rod 448 connected to the buckle 424.

[0078] like Figure 26As shown, the first longitudinal end 440 has a first lateral width W1, and the second longitudinal end 442 has a second lateral width W2 greater than the first lateral width W1. In the illustrated example, the side of the buckle 424 tapers linearly from the wider second longitudinal end 442 to the narrower first longitudinal end 440. In other embodiments, the first longitudinal end 440 may be pointed. In other embodiments, the first longitudinal end 440 may be rounded. In the illustrated example, the second longitudinal end 442 is flat or straight and parallel to the rod 448. In other embodiments, the second longitudinal end 442 may be convex, polygonal, or concave.

[0079] The narrower width of the first longitudinal end 440 facilitates easier slippage of the ring 32 over the first longitudinal end, thus making it easier to connect and disconnect. Furthermore, the narrower width of the first longitudinal end 440 provides a visual cue to indicate which end of the buckle 424 the ring 32 will initially receive. The wider width of the second longitudinal end 442 overlaps more with the ring 32 connected from below than the narrower first longitudinal end 440, thereby reducing the likelihood of the buckle accidentally slipping through the ring 32 and breaking off from it.

[0080] like Figure 23 and Figure 26 As shown, the buckle 124 also includes a retainer 458. The retainer 458 is configured to extend at least partially along the bottom surface and / or a portion of the flexible length associated with the ring 32 to retain and secure the ring 32 to the buckle 424. In the illustrated example, the retainer 458 includes a pair of opposing retaining arms 460-1 and 460-2 (collectively referred to as arms 460). The retaining arms 460 project downward from the bottom surface 438 of the buckle 424 and are configured to contact or engage the ring 32 to inhibit lateral outward movement of portions of the ring 32 relative to the buckle 24. In the illustrated example, the retaining arms 460 are in the form of inwardly projecting tabs or hooks to further inhibit downward movement of the ring 32 away from the bottom surface 38 of the buckle 124. Figure 23 and Figure 25 As shown, retaining arm 460-1 extends at the second longitudinal end 442 on the first lateral side of body 434, and the first retaining arm 460-1 extends downward and inward toward the second lateral side of body. Retaining arm 460-2 extends at the second longitudinal end 442 on the second lateral side of body 434, and the second retaining arm 460-2 extends downward and inward toward the first lateral side of body. As described above, in some embodiments, the retainer 458 formed by the retaining arms 460 can be replaced by a single clamp, such as the clamp 360 described above with respect to buckle 324.

[0081] like Figure 28 and Figure 29As shown, the shape of the buckle body makes the bottom surface 438 of the buckle concave. The concave shape of the bottom surface of the buckle can extend from the first opening 444 to the second longitudinal end 442. This concave shape can form a laterally extending cavity for receiving the various parts of the ring 32, thereby further assisting in maintaining the connection between the ring 32 and the buckle 424.

[0082] like Figure 25 and Figure 27 As shown, the first longitudinal end 440 of the buckle 424 includes a vertical wall 480 extending downward from the bottom surface 438 of the buckle 424. The vertical wall 480 provides a vertical surface facing the second longitudinal end 442 of the buckle. In some embodiments, the vertical wall 480 may be perpendicular to the plane of the buckle 424 or the top surface of the flexible length 28. In other embodiments, the vertical wall 480 may be angled downward or inclined relative to the plane of the buckle relative to the top surface of the flexible length. Figure 27 As shown, the vertical wall 480 may be concave, with a radius similar to or corresponding to the radius of the closed end 49 of the ring 32, the concave profile facing backward away from the longitudinal end 442. In some embodiments, the vertical wall 480 may extend from a first lateral side or edge to a second lateral side or edge. In some embodiments, the vertical wall 480 may extend only a portion of the total lateral width of the buckle 424. The vertical wall 480 helps to inhibit movement of the flexible ring 32 toward and beyond the first longitudinal end 440 of the buckle, thereby helping to retain the ring 32 around the buckle 424. After the buckle 424 passes through the ring 32, the closed end 49 of the ring 32 may be clamped between the top surface of the end of the flexible length 28 connected to the rod 448 and the lower side or bottom surface 438 of the buckle 424, and the closed end 49 of the ring 32 is further clamped between the upwardly curved portion of the top surface of the end of the flexible length 28 connected to the rod 448 and the vertical wall 480. The vertical wall 480 can also serve as a front hook, and the closed end 49 of the ring 32 can be initially fixed around the front hook, which further helps to fit the ring 32 onto the buckle 424, fix it around the buckle 424, and secure it to the buckle 424.

[0083] In the example shown, buckle 424 is integrally molded as part of a single monolithic body. For example, buckle 424 may be molded as a single piece or part from one or more polymers (e.g., thermoplastics), metals (e.g., aluminum), ceramics, composites, and / or fiber composites. In other embodiments, buckle 424 may be made without any fasteners, welding, bonding, or other mechanical or chemical connections. In other embodiments, buckle 424 may be made from multiple interconnected components. For example, buckle 424 may be molded or otherwise formed as a single piece, except for rod 448, which includes a separate bar or other component attached to the molded body of buckle 424. In other embodiments, the outer contour of buckle 424 may have a shape other than the trapezoid shown.

[0084] Figures 30-34 The movement of ring 32 and buckle 424 is shown. Figure 33 and 34 The process of the connection state shown. For example... Figure 30 As shown, the closed end 49 of ring 32 is brought onto end 440 (as indicated by arrow 454). Figure 3 As shown, after end 440 passes through opening 56 of ring 32, ring 32 can move in a direction away from end 440 (as indicated by arrow 456), and end 42 can be lifted through opening 56 (or ring 32 can be lowered and pass through end 442). It should be understood that the relative movement of buckle 24 and ring 32 can be achieved in various different ways. Ultimately, buckle 424 completely passes through opening 56 to enter... Figure 32 The connection status is shown.

[0085] like Figure 32 As shown, in the connected state, ring 32 is completely below buckle 424. The closed end 49 of ring 32 is sandwiched between the top surface of the end 26 of flexible length 28 and the lower side or bottom surface 438 of buckle 424. To activate the disconnected state of system 22, the closed end 49 moves forward (…). Figure 33 (left side of the ring 32), and the shape of the closed end 49 allows the closed end 49 of the ring 32 to be lifted beyond the end 440, allowing the buckle 424 to move to the right (e.g., on the left side of the ring 32), and the shape of the closed end 49 allows the closed end 49 of the ring 32 to be lifted beyond the end 440, allowing the buckle 424 to move to the right side (e.g. Figure 31 As shown), thus pulling the buckle 424 out from the opening 56 of the ring 32 (usually with... Figure 31 and Figure 32 (The opposite of what is shown).

[0086] like Figure 33 and Figure 34As shown, once the body 434 of the buckle 424 passes through the opening 56 of the ring 32, the connected portion of the ring 32 and / or the flexible length 28 is lifted and moved or bent inward, thereby allowing the portions of the ring 32 and / or the flexible length 28 to pass through the opening 467 (as shown). Figure 26 (As shown) Positioned between the arms 460 and entering the channel 466 formed by the bottom surface 438 of the buckle 424 and the retaining arm 460, thereby preventing portions of the ring 32 and / or the flexible length 28 from being pulled out of the channel 466. As a result, portions of the flexible ring and / or the associated flexible length are captured and held within the channel 466, abutting against the bottom surface 438 of the buckle 424 to prevent movement of the ring 32 away from the buckle 424 and to prevent the buckle 424 from accidentally looping back through the ring 32. The retaining arm 460 further inhibits accidental rotation of the ring 32 relative to the buckle 424 (e.g., when the buckle 424 and the ring 32 are not tightened) to hold the closed end 49 of the ring 32 along the first longitudinal end 440 and around the buckle 424. The inwardly extending protrusions 470 of the arm 460 form latches or hooks that form the bottom of the channel 166, wherein the bottom surface 38 of the body 434 opposite to the hook forms the top of the channel 466, and wherein the hooks or inwardly extending protrusions 470 extend along the bottom surface of the ring 32 and form the bottom of the channel 166. In some embodiments, the inwardly extending protrusions 470 may be omitted.

[0087] Figure 35 and Figure 36 Two different examples of a seat belt 520 with a connection system 420 are shown. Each example seat belt 520 and 520' includes three main components: a lap belt 524 (sometimes referred to as "swami") and a pair of leg loops 526-R and 526-L (collectively referred to as leg loops 526). In some embodiments, the seat belt 520 may include additional main components that wrap around or wrap around the shoulders and / or chest of the person wearing the seat belt 520. The lap belt 524 is configured to support the leg loops 526 through the waist of the person wearing the seat belt 520. The lap belt 524 is also configured to attach to a tether, rope, cable, or other flexible line, and the lap belt 524 may be suspended by an upper support to limit the extent to which the lap belt 524 and the person wearing the seat belt 520 may fall off the upper support. The belt 524 includes a wide strip portion 530, narrow extension portions 532-1 and 532-2 (collectively referred to as narrow extension portion 532), a connector 534, a tether support line connector 536, and an equipment ring 538.

[0088] The wide strip portion 530 includes an elongated strip configured to wrap around the waist of the person wearing the seatbelt 520. The width of the wide strip portion 530 allows it to distribute force along a larger surface area (in contrast to a single straight line), thus providing a more comfortable experience for the person wearing the seatbelt 520. The width of the wide strip portion 530 is uneven along its length, being wider at the rear 539 and narrower at the front portions 540-1 and 540-2. In some embodiments, the wide strip portion 530 is configured to lie on the iliac crest of the hip bone. In these embodiments, the wide strip portion 530 may have a banana-like curved shape.

[0089] Narrow extensions 532-1 and 532-2 extend from the front portions 540-1 and 540-2 of the wide strip portion 530, respectively. The width of each narrow extension 532 is less than the width of the rear portion 539, and in the illustrated example, less than at least a portion of the front portion 540. In the illustrated example, the narrow extension 532 includes strips respectively connected to a connector 534. In the illustrated example, the connector 534 includes a buckle or a pair of rungs, wherein at least one narrow extension 532 is configured to pass through the rungs or buckle to provide an adjustable length for the waist belt 524.

[0090] Connector 534 releasably connects to narrow extension 532 to secure lap belt 524 around the waist of a person wearing seatbelt 520. In the illustrated example, connector 534 includes a quick-disconnect connector in the form of a side-opening buckle. In the illustrated example, the side-opening buckle is connected to narrow extension 532-1 such that narrow extension 532-1 has an adjustable length extending between front end 540-1 and connector 534. In other embodiments, narrow extension 532-1 may be connected to connector 534 and have a fixed length between front end 540-1 and connector 534. In other embodiments, connector 534 may include other types of connectors.

[0091] Tethered support line connector 536 (sometimes also called a belay loop, such as...) Figure 35 (As shown) provides a connection point for the tethered support line, which can be a rope, cable, strap, or the like, used for suspension to the upper support. See also Figure 36 The tether support cable connector 536 includes two loops formed by the upper end of a narrow extension 556 of the leg loop 526, wherein the tether support cable is "tied" into the two loops. In some embodiments, such loops may be made of nylon, polyester fiber, ultra-high molecular weight yarn, liquid crystal polymer (e.g., VECTRAN). TM It is made of materials such as fibers or other fibers.

[0092] Equipment loop 538 includes a loop extending from the wide strip portion 30. Equipment loop 538 is configured to attach to various pieces of equipment that can be suspended on a belt 524. In some embodiments, belt 524 may include an additional equipment loop 538.

[0093] Leg loops 526-R and 526-L extend and suspend from the left and right front sides of the lap belt 524, respectively. Leg loops 526-R and 526-L are configured to wrap around the left and right thighs of the person wearing the seatbelt 520. The leg loops 526 are substantially identical to each other. Each leg loop 526 includes a wide strip portion 550, a narrow extension portion 552, a connecting system 420, a narrow extension portion 556, and a leg loop riser 558.

[0094] The wide strap portion 550 includes a wide strap configured to sit below a person's thigh, distributing force over a larger surface area to provide a more comfortable experience for the thighs of the person wearing the seatbelt 520. The wide strap portion 550 has an uneven width along its length, tapering towards the narrower extensions 552 and 556. In such applications, the wide strap portion 550 can have a banana-like curved shape. Its minimum width is 43 mm when used as part of a lap belt and when used as part of a leg loop.

[0095] A narrow extension 552 extends from the wide strip portion 550, extending along the inner thigh of the person wearing the seatbelt 520. The narrow extension 552 may be more flexible, more bendable, or more prone to twisting compared to the wide strip portion 50. In the example shown, the maximum lateral width of the narrow extension 552 is no greater than 75% of the maximum lateral width of the wide strip portion 550.

[0096] The buckle 424 of the connecting system 420 can releasably connect one end of the wide strip portion 550 to the narrow extension portion 556, thereby completing a loop around a person's thigh.

[0097] A narrow extension 556 extends from the wide strap portion 550 and connects to or is attached to the waist belt 524. Narrow extensions 556 of the leg loops 526 are connected to each other (or become part of a single integrated strap, band, rope, or the like) and pass through the tether support connector 536 (i.e., the protective ring 536). See also Figure 36 Each narrow extension 556 may be further interconnected via a transverse member 537 to form a tie point or loop 559. In other embodiments, the narrow extensions 556 are otherwise connected to the belt 524.

[0098] The leg loop riser 558 includes a strap, rope, or similar material. A first end of the leg loop riser 558 is connected to the underside of the corresponding leg loop 526 (the underside of the wide strip portion 550), and a second end of the leg loop riser 558 is connected to the rear of the waist belt 524 (the rear portion 539 of the wide strip portion 530). The leg loop riser 558 helps to support the leg loop 526 and supports the leg loop 526 to suspend it on the waist belt 524.

[0099] Figure 36 This is a perspective view of the seatbelt at 520'. Figure 35 A variant of seat belt 520 is shown. Seat belt 520' is similar to seat belt 520, except that narrow extensions 556 of leg loops 526 are interconnected (or form part of a single integral strip, strap, rope, or the like) and pass through tether support line connector 536 (i.e., protection ring 536). Each narrow extension 556 is further interconnected by transverse members 537 to form tethering points or loops 559. Other components in seat belt 520' corresponding to similar components of seat belt 520 are referred to in similar way.
