Description
1 / 23 “TRACE ROUTING FIXTURE” RELATED REQUEST
[001] This application claims priority to U.S. Provisional Patent Applications No. 63 / 696,408, filed September 19, 2024, and No. 63 / 780,561, filed March 31, 2025, both entitled “Trace Routing Fastener”, each of which is incorporated herein by reference. FUNDAMENTALS OF THE INVENTION
[002] Automotive components require fastening techniques that are simple to manufacture and assemble. Furthermore, fastening techniques must, above all, be reliable and efficient. In some cases, objects need to be secured to the vehicle to dampen movement and / or displacement during operation, which can result in damage or twisting of the object. For example, pipes, hoses, wires, and other objects are frequently attached to vehicle components using fasteners. When a fastener is installed incorrectly, such that it is not fully inserted into the opening, the fastener may become detached and / or the object being secured may be damaged or come loose. Similarly, when an object is incorrectly secured to a fastener, the object may become detached from the fastener or be damaged or come loose.
[003] Conventional fastening or mounting systems often require the use of heavy screws and tools during installation on assembly lines. This not only increases the overall weight of the system, but also introduces complexity, higher labor demands, and potential delays in the manufacturing process.
[004] Therefore, it would be desirable to provide an installation indicator to enhance the proper installation of the object in relation to the fastener and / or the fastener in relation to the first component during assembly. SUMMARY OF THE INVENTION
[005] The present description refers, in general, to a fastening system for forming a connection between the first and second components, such as pipes and Petition 870250084217, dated 09 / 18 / 2025, page 9 / 50 2 / 23 panels.

In other words, “x, ye / or z” means “one or more of x, y and z”.
[030] The fastener assembly described, according to one aspect of the description, addresses deficiencies in the technique through an all-plastic construction that eliminates the need for tools during assembly, thus simplifying the installation process and reducing weight. The design also allows for visual or automated verification of the assembly through integrated features compatible with vision systems. Specifically, the design incorporates scannable elements that allow for real-time confirmation of proper assembly without physical inspection or manual validation.
[031] In one example, a fastening system configured to fasten one or more second components to a first component comprises: a base structure defining a grommet portion and a carrier portion, the carrier portion including a fiducial support with Petition 870250084217, dated 09 / 18 / 2025, page 14 / 50 7 / 23 an installation indicator; and a locking pin comprising a rod and a head, the head including a fixed part and a flap pivotingly coupled to the fixed part, wherein the flap is movable between a first position and a second position relative to the installation indicator, and wherein the flap is configured to pivot by engaging with the fiducial support during the advancement of the locking pin to a fully seated position, thus allowing the installation indicator to be read by a visual quality system.
[032] In some examples, the flap is attached to the fixed part by means of one or more film hinges.
[033] In some examples, in the first position, the tab covers at least partially the installation indicator to indicate that the locking pin is not fully seated.
[034] In some examples, the base structure comprises one or more flexible tab elements configured to engage a window in the first component, the flexible tab elements deflecting during insertion and returning to an extended position to retain the base structure.
[035] In some examples, the fiducial support is positioned at an angle relative to the transport part to optimize detection of the installation indicator by the visual quality system.
[036] In some examples, the tab is attached along an outer edge of the fixed part.
[037] In some examples, moving the tab to the second position provides visual confirmation of the proper installation of the locking pin in relation to the base structure.
[038] In some examples, the fastening system further comprises a strap and a strap opening in the transport part, the strap configured to fasten one or more secondary components to the transport part. Petition 870250084217, dated 09 / 18 / 2025, p. 15 / 50 8 / 23
[039] In another example, a locking pin assembly for use with a base structure comprising a fiducial support carrying an installation indicator, the locking pin assembly comprising: a rod; a head including a fixed part and a flap pivotingly coupled to the fixed part; and wherein the flap is movable between a first position and a second position relative to the installation indicator, and wherein the flap is configured to pivot by engaging with the fiducial support during the advancement of the locking pin to a fully seated position, thus allowing the installation indicator to be read by a visual quality system.
[040] In some examples, the head further comprises a pair of flexible arms extending from the stem, each flexible arm having a first notch and a second notch configured to engage a tongue in the base frame to hold the locking pin in a transport position and a fully installed position.
[041] In some examples, the flap is configured to pivot by engaging with the fiducial support.
[042] In some examples, the flap is pivoting around a pivot axis formed along an outer edge of the fixed part.
[043] In some examples, the installation indicator comprises a barcode, QR code or other machine-readable symbol.
[044] In some examples, the fiducial support is a block-shaped structure, at least partially received by a window in the fixed part of the locking pin head.
[045] In yet another example, a fastening system configured to fasten one or more second components to a first component comprises: a base structure comprising a carrying part and one or more tabs; a locking pin comprising a rod and a head, the head including a fixed part, a tab pivotingly coupled to the fixed part, and a pair of flexible arms that Petition 870250084217, dated 09 / 18 / 2025, page 16 / 50 9 / 23 extend from the shaft, each flexible arm having a first notch and a second notch configured to engage the tongue to hold the locking pin in a transport position and a fully installed position, respectively; and wherein the tab is movable between a first obstructive position and a second non-obstructive position relative to an installation indicator mounted on a fiducial support of the transport part, the tab pivoting upon engagement with the fiducial support as the locking pin advances to a fully seated position.
[046] In some examples, the flexible arms are configured to deflect inward in order to disengage the tongue from the first notch during the advance of the locking pin.
[047] In some examples, the tongue engages with the second notch of the flexible arms to lock the locking pin in the fully installed position.
[048] In some examples, the fiducial support is positioned to stabilize the tab and maintain a consistent angle of the installation indicator for visual detection.
[049] In some examples, improper seating of the locking pin prevents the tab from pivoting fully, resulting in at least partial obstruction of the installation indicator.
[050] In some examples, the base structure further comprises an eyelet part that defines an eyelet opening configured to receive the locking pin rod.
[051] Figures 1a and 1b illustrate a fastening system 100 configured to fasten one or more second components 110 to a first component 104 by means of a fastener assembly 102 which includes a locking pin 108 and a base structure 116, according to a first aspect of this description. The fastening system 100 generally includes a fastener assembly 102, which is a multicomponent assembly configured for installation on a first component 104. One or more second components 110 may be fastened to a part of the fastener assembly 102. The first component 104 defines an opening 106 configured to receive and retain the Petition 870250084217, dated 09 / 18 / 2025, p. 17 / 50 10 / 23 fastener set 102.
[052] The first component 104 includes a side surface A 104a (e.g., outer surface) and a side surface B 104b (e.g., inner surface). One or more second components 110 are mounted on the side surface A 104a by means of the fastener assembly 102. The first component 104 may comprise structural or body elements of a vehicle, such as doors, pillars (A, B or C pillars), panel components, seat structures, center consoles, fenders, sheet metal structure or similar elements.
[053] Depending on the application, the first component 104 may be formed from metal, metal alloys, synthetic or semi-synthetic polymers (e.g., ABS or PVC), composite materials (e.g., fiberglass), or combinations thereof. The opening 106 may be formed integrally during manufacturing and is generally rectangular in the example illustrated, although other geometries—such as circular, oval, triangular, or other quadrilateral openings—are also considered. The second components 110 may include brake lines, fuel lines, electrical cables, piping, or other tubular or elongated structures.
[054] Details of fastener assembly 102 are illustrated in more detail in Figures 2a to 2l. Specifically, Figures 2a and 2b show perspective views of fastener assembly 102 in a first assembled position (Position A) and in a second assembled position (Position B), respectively. Figures 2c and 2d show side elevation views of fastener assembly 102 in the same two positions. Figures 2e and 2f represent side elevation cross-sectional views of fastener assembly 102, taken along the section line AA in Figure 2a, in positions A and B, respectively. Figures 2g and 2h represent, respectively, perspective and cross-sectional views of fastener assembly 102, taken along the section line BB in Figure 2g, at Position A. Figures 2i and 2j represent, respectively, perspective and cross-sectional views of fastener assembly 102, taken along the section line BB of Petition 870250084217, dated 09 / 18 / 2025, p. 18 / 50 11 / 23 Figure 2g, in Position B. Figures 2k and 2l show top plan views of fastener assembly 102 in positions A and B, respectively.
[055] The fastener assembly 102 illustrated comprises multiple components, including a locking pin 108 and a base frame 116. In some examples, the fastener assembly 102 may be pre-assembled in the first assembled position to serve as a pre-installation configuration shipped (Position A). The fastener assembly 102 also includes one or more elements in the base frame 116 that facilitate attaching the second component 110 to it by means of a strap 140. For example, the base frame 116 includes a transport part 116a and a fastening part 116b. The transport part 116a and the fastening part 116b may be formed as a single unitary component. Alternatively, the fastening part 116b may be attached to the transport part 116a by means of adhesives, welding, mechanical fasteners, or other joining methods.
[056] Additional elements, such as ribs, tabs, linings, padding, etc., may be incorporated to attenuate buzzing, squeaking and rattling (BSR) between the fastener assembly 102 and the first component 104 and / or the second component 110. The carrier part 116a is configured to engage one or more second components 110 and secure them relative to the first component 104. In the example illustrated, the carrier part 116a includes a payload part 134 and a grommet part 136.
[057] The payload part 134 interfaces with the second component 110, while the eyelet part 136 defines an eyelet opening 138 configured to receive at least one part of the locking pin 108. The eyelet part 136 further comprises a fiducial support 112 carrying an installation indicator 126, such as a barcode or QR code, which can be detected by a visual quality system 120. In the illustrated example, the fiducial support 112 is formed as a generally block-shaped structure with an upper surface having the installation indicator 126 on it. Petition 870250084217, dated 09 / 18 / 2025, p. 19 / 50 12 / 23 an external surface thereof. The fiducial support 112 may be hollow or partially perforated to conserve material and reduce weight. The fiducial support 112 is dimensioned to correspond to a window 148 formed in the fixed part 128b of the locking pin head 128. During assembly, the fiducial support 112 is guided inward and at least partially received by the window 148.
[058] In the fully seated condition (Position B), the upper surface of the fiducial support 112, which carries the installation indicator 126, aligns and / or is substantially flush with the surrounding upper surface of the fixed part 128b, as illustrated in Figure 2i. This block-and-window engagement between the fiducial support 112 and the window 148 provides several functional benefits. First, it stabilizes the fiducial support 112 relative to the locking pin 108, preventing lateral displacement or rotation that could otherwise misalign the installation indicator 126. Second, it ensures repeatable and consistent positioning of the installation indicator 126 in a known plane and orientation, which improves the accuracy and reliability of detection by the visual quality system 120. Third, the positive seating of the fiducial support 112 within the window 148 provides tactile and visual confirmation of correct installation, further reducing assembly errors.Finally, the use of a hollow or lightweight block structure reduces the overall cost and mass of the parts, while providing sufficient rigidity to support and protect the 126 installation indicator during handling and maintenance.
[059] The fastening part 116b is configured to connect the transport part 116a to the first component 104. In the illustrated example, the fastening part 116b is configured to fit into the opening 106 of the first component 104 during installation.
[060] In the illustrated example, a strap opening 142 is defined through the payload part 134. There may be one or more openings for strap 142. A strap 140 is placed through the strap opening 142 and wrapped around for one or more seconds. Petition 870250084217, dated 09 / 18 / 2025, page 20 / 50 13 / 23 components 110, with the free ends secured using a strap fastener 144. Suitable strap fasteners 144 may include ratchet mechanisms, latches, snap fasteners, clips, Velcro fasteners or cable ties (e.g., plastic cable ties). Although a single strap 140 is illustrated, additional or fewer straps 140 and strap openings 142 may be used, depending on design requirements and the number of secondary components 110 to be secured.
[061] The dimensions of the transport part 116a can be modified to accommodate the required number of straps or components. Although described in the context of pipe clamping, the fastening assembly 102 can be used to secure various other objects. During installation, a front end 132 of the fastening part 116b is inserted into the opening 106 of the first component 104 in the direction shown by arrow 118. The fastening part 116b generally extends perpendicularly to the transport part 116a and includes a central longitudinal axis 114. In the illustrated example, the fastening part 116b comprises a pair of resilient legs 150 fixed to the lower part of the transport part 116a. The distal ends of the resilient legs 150 converge and are connected at the front end 132. The fastening part 116b may further comprise one or more elements formed on the outer surfaces of the resilient legs 150.
[062] US Patent Application No. 19 / 233,139, a common property filed on June 10, 2025, and entitled “Trace Routing Fastener,” describes a fastening part 116b with steps extending circumferentially or partially circumferentially around the leg surface and includes a protruding or shoulder-like element configured to grip or engage the inner surface of the opening 106 formed in the first component 104. A multi-step engagement helps ensure a firm fit, compensates for dimensional variation, and attenuates buzzing, squeaking, and rattling (BSR) noise during use or vibration. US Patent Application No. 19 / 233,139 is incorporated herein by reference as follows. Petition 870250084217, dated 09 / 18 / 2025, p. 21 / 50 14 / 23 was fully established here.
[063] The locking pin 108 and the base structure 116 can each be formed as unitary components using plastic injection molding or additive manufacturing. In additive examples, the components can be manufactured by fused deposition modeling (FDM), stereolithography (SLA), selective laser sintering (SLS), or other 3D printing methods, offering precision and flexibility, particularly for complex geometries and low-volume production. Additive manufacturing processes consider horizontal resolution (XY plane) and vertical resolution (layer thickness on the Z axis). Horizontal resolution typically ranges from 50 to 100 μm (510 to 250 DPI), while vertical resolution can range from 16 to 100 μm (1600 to 250 DPI). Higher resolutions produce finer details but increase production time. Different parts of the 102 fastener assembly can be printed at different resolutions based on functional or design needs.
[064] Improper installation of the second component 110 or fastener assembly 102 may lead to detachment or misalignment. Improper fastening may also damage or loosen the first component 104. To aid in tracking the installation, the locking pin 108 includes a head 128 attached to the rod 152. The head 128 comprises a fixed part 128b and one or more tabs 128a that can pivot relative to the fixed part around a pivot axis 130. The tab 128a is connected to the fixed part 128b by means of one or more film hinges 156, which allows for pivoting movement. In the illustrated example, the tab 128a is connected to the fixed part 128b by means of a pair of spaced film hinges 156, which is best illustrated in Figure 2k. In the illustrated example, the head 128 includes a fixed part 128b with a window 148 with a single flap 128a attached in a hinged manner. During assembly, the flap 128a is tilted or pivoted via the fiducial support 112.
[065] When the head 128 is fully seated (Position B), the flap 128a Petition 870250084217, dated 09 / 18 / 2025, page 22 / 50 15 / 23 pivots upward and away so that the installation indicator 126 is not obstructed by tab 128a, allowing the visual system 120 to fully read the installation indicator 126. In intermediate or pre-installation positions (Position A), tab 128a is tilted to at least partially obstruct the installation indicator 126, making the installation indicator 126 illegible or at least reflecting that it is partially obstructed by tab 128a. Contact with the fiducial support 112 causes tab 128a to pivot upward as the locking pin 108 is pushed into place.
[066] If locking pin 108 is installed incorrectly, tab 128a will at least partially obstruct installation indicator 126, resulting in a misaligned position. This misalignment prevents the visual quality system 120 from reading (or fully reading) installation indicator 126, signaling an improper assembly. In some examples, an installation indicator may be additionally (or alternatively) positioned on tab 128a. In this example, the visual quality system 120 may read the installation indicator positioned on tab 128a or use it to determine an angle of tab 128a, thus being able to determine if and by what degree locking pin 108 is positioned between Position A and Position B.
[067] The fastener assembly 102 is configured to be mounted on a first component 104, such as a vehicle frame, after having been pre-attached to a second component 110 (for example, an electrical harness) using a strap 140, such as a plastic clamp or a cable tie. During installation, the fastener assembly 102 may first be attached to a first set of components using the strap 140.
[068] As shown in Figures 2a and 2c, during transport and before installation, the locking pin 108 is held in a part-in-assembly (PIA) position relative to the base frame 116. This is achieved by means of the engagement between a locking tab, located on the locking pin 108, and a corresponding element on the frame. Petition 870250084217, dated 09 / 18 / 2025, page 23 / 50 16 / 23 base 116. The locking tab may be formed as a fixed lateral protrusion extending from the rod 152 of the locking pin 108. The locking tab is configured to produce an interference fit with the base frame 116, temporarily holding the locking pin 108 in its first position (PIA) (Position A). For example, the locking tab may engage with an inner wall of the grommet opening 138 or with a structural element, such as a notch, recess or protrusion, within a cavity or recess located between a pair of resilient legs 150 of the base frame 116.
[069] The base structure 116 may further include one or more flexible flap elements 146, which are integrally formed with, or fixed to, the resilient legs 150. These flexible flap elements 146 are designed to retain the base structure 116 within a first component 104, engaging in an opening 106 when the fastening system is in its second assembled position. These flexible flap elements 146 are located near the proximal ends of the legs, close to the point where each leg connects to the transport part 116a.
[070] Each flexible flap element 146 comprises an inclined body part, such as a triangular or wedge-shaped flap, and a movable base part, which is elastically or pivotally coupled to its respective elastic leg 150. These flexible flap elements 146 are designed to deflect towards or away from the central longitudinal axis 114 during insertion into the opening 106. For example, as the base structure 116 is pressed against the first component 104, an outer edge of the opening 106 applies a thrust force to the inclined part, causing the flap 146 to temporarily retract.
[071] Once the flexible flap elements 146 are removed from the opening 106, they resiliently return to their original extended positions. A part of the inclined body, such as its upper edge, then rests against a surface of the first component 104 (for example, an inner side wall of the opening 106), attenuating the recoil of the base structure 116. The locking pin 108 then advances through the Petition 870250084217, dated 09 / 18 / 2025, page 24 / 50 17 / 23 opening of the eyelet 138 until reaching a second assembled position.
[072] Before complete installation, the visual quality system 120 cannot read the installation indicator 126 positioned on the fiducial support 112 (or, at least, can detect that the installation indicator 126 is at least partially obstructed). Once fully seated, the resilient legs 150 extend outwards (see arrows 154a and 154b, Figure 1a), anchoring the base structure 116 within the first component 104. Simultaneously, the tab 128a moves away from the installation indicator 126, allowing the visual system 120 to verify the installation. During the final installation of the fastener assembly 102 in the first component 104, continuous pressure (direction of arrow 118) causes the locking pin 108 to advance to its fully seated position.
[073] In addition, the locking tab on the locking pin 108 engages with the protrusion elements on the base frame 116. These elements cooperate to prevent axial recoil of the locking pin 108, either from the transport position (Position A) or from the final installation position (Position B), thus improving the retention and overall robustness of the system. In some respects, the locking pin 108 includes a channel 158 formed along at least part of the rod 152. This channel aligns with the flexible tab elements 146 during insertion, allowing them to move freely towards and away from the shaft 114.
[074] In configurations where the flexible tabs 146 are positioned asymmetrically, the channel 158 may also be located asymmetrically to match. In other designs, the channel 158 may be omitted. In these cases, the rod 152 obstructs the inward movement of the flexible tab elements 146, keeping them in an outward unfolding state. This locked configuration may be desirable where maximum mechanical restraint, structural rigidity or vibration resistance is required, such as in aerospace, automotive or structural panel applications.
[075] Figures 3a and 3b illustrate a second example of the fastening system. Petition 870250084217, dated 09 / 18 / 2025, page 25 / 50 18 / 23 100, configured to fasten one or more second components 110 to the first component 104 by means of a fastener assembly 102 which includes a locking pin 108 and a base frame 116, according to a second aspect of this description.
[076] The fastener assembly 102 in Figures 3a and 3b is generally similar in structure and function to the fastener assembly described above with reference to Figures 1a to 2l. Consequently, to avoid redundancy, the emphasis in this section will be placed on the differences between the two examples. Unless otherwise indicated, the various elements described together with the first example provide a similar or equivalent function in the present example and, for the sake of brevity, will not be repeated in detail. In this second example, the tab 128a of the locking pin 108 is positioned so as to engage a fiducial support 112 located on or adjacent to the payload part 134.
[077] Figures 4a and 4b show perspective views of fastener assembly 102 in positions A and B, respectively. Figures 4c and 4d show side elevation views in positions A and B, respectively. Figures 4e and 4f show side elevation cross-sectional views taken along section line CC of Figure 4g in positions A and B, respectively. Figures 4g and 4h show perspective and cross-sectional views taken along section line CC of Figure 4g in Position A, respectively. Figures 4i and 4j show perspective and cross-sectional views taken along section line CC of Figure 4g in Position B, respectively. Figures 4k and 4l show top plan views in positions A and B, respectively.
[078] In this second example, the locking pin head 128 includes a rod 152 flanked on both sides by a pair of flexible arms 402. Each flexible arm 402 is formed by a first notch 406 and a second notch 404, which function as engagement surfaces for a tongue 408 mounted on the base frame 116. The first notch 406 is configured to receive the tongue 408 and secure the pin. Petition 870250084217, dated 09 / 18 / 2025, page 26 / 50 19 / 23 locking pin 108 in the transport or pre-installation position (Position A). The second notch 404 is configured to engage the tongue 408 once the locking pin 108 is fully installed, thus securing the locking pin in the final mounting position (Position B).
[079] During installation, the locking pin 108 is pushed in the direction indicated by arrow 118. The applied force causes the rod 152 and the flexible flanking arms 402 to deflect inward, overcoming the engagement of the tongue 408 with the first notch 406. As the locking pin 108 continues to advance, the tongue 408 slides along the flexible arm 402 until it engages with the second notch 404, thus locking the pin in the installed position (Position B).
[080] In this example, the pivoting tab 128a is coupled to the fixed part 128b along an outer edge of the fixed part, instead of being hinged in a window as in the first example. This outer edge coupling allows the tab 128a to pivot upwards and out of the way during installation, clearing the line of sight to the installation indicator 126.
[081] The installation indicator 126 is mounted on a fiducial support 112, which is angled to position the indicator ideally for reading and analysis by a visual quality system 120. This arrangement ensures that the visual system can reliably detect correct installation, while incorrect seating of the locking pin 108 or incomplete movement of the tab 128a will be immediately indicated by an incorrectly read or partially obstructed installation indicator 126.
[082] Figures 5a and 5b illustrate, respectively, isometric views of the fastener assembly 102 with the first component 104 and a visual quality system 120. The fastener system 100 can be used in conjunction with a visual quality system 120, which includes a reader 122 and a computer 124. The reader 122, which can be connected to the computer 124 via a connection with Petition 870250084217, dated 09 / 18 / 2025, page 27 / 50 20 / 23 or wireless, it is positioned adjacent to the fastener assembly 102 and / or the first component 104 to monitor the assembly process, including the insertion of a second component 110.
[083] As in the previous examples, elements not specifically highlighted here may be understood as providing the same or an equivalent function to that described above and, for the sake of brevity, will not be repeated. In some examples, the head 128 is designed so that one or more installation indicators 126 remain hidden from the visual quality system 120 until the locking pin 108 is fully assembled. Specifically, if the locking pin 108 is not fully engaged, the tab 128a will not be flush with the fixed part 128b, and the system will be unable to detect the installation indicator 126 or will detect an incorrect angle.
[084] In both cases, the visual quality system 120 registers an error or anomaly. Based on the data from the installation indicator 126, the computer 124 (by means of the processor 124a and the memory 124b) can determine whether the fastener assembly 102 is correctly installed on the first component 104. If an improper installation is detected, the system can alert an operator, for example, by means of a portable communication device. In automated or robotic applications, the robot can automatically repeat the assembly process to correct the error.
[085] Although a single installation indicator 126 is illustrated, multiple indicators can be used to increase redundancy or accuracy by providing multiple positional data points. Furthermore, indicators can be located in other parts of the fastener assembly 102, such as on a side wall of the transport part 116a, as a supplement or replacement for the head-mounted indicator. The installation indicator 126 is fixed to the fiducial support 112, printed directly, applied as a label, or fixed by another method. The tab 128a is connected to the fixed part 128b by hinges 156 and can pivot between obstructive and non-obstructive positions. Petition 870250084217, dated 09 / 18 / 2025, page 28 / 50 21 / 23 obstructive.
[086] Figure 6A illustrates a fastening system 100 configured to fasten one or more second components relative to a first component by means of a fastener assembly 102 which includes a locking pin 108 and a base structure 116, according to a third aspect of this description. The fastening system 100 is shown in a first assembled position. Figure 6B illustrates a cross-sectional view of the fastener assembly 102 taken along the cutting line DD in Figure 6A, and Figure 6C illustrates an exploded view of the fastener assembly 102 corresponding to Figures 6A and 6B.
[087] The fastener assembly 102 in Figures 6A to 6C is substantially the same as the fastener assembly 102 in Figures 2A to 2L, except for the mechanical interaction between the rod 152 and the fastening part 116B. In this example, instead of positioning locking tabs on the base frame 116 to hold the locking pin 108 in place until the base frame 116 is inserted into the opening 106 of the first component 104, locking elements are formed on the locking pin 108 itself. For example, the locking pin 108 illustrated includes a locking tab 602 resiliently coupled to the fixed part 128b and / or the rod 152, the locking tab 602 being configured to engage the base frame 116 in order to secure the base frame 116 and the locking pin 108 in a transport position (Position A). As shown in the cross-sectional view of Figure 6B, the locking tab 602 attaches to the base frame 116 at or adjacent to the eyelet opening 138.The rod 152 may additionally include one or more protrusions 606 (illustrated as ramps) positioned on an outer surface of the rod 152 along its length. These protrusions 606 are configured to engage one or more ridges 604 formed on an inner surface of each of the pair of resilient legs 150.
[088] Figure 7A illustrates a fastening system 100 configured to fasten one or more second components to a first component by means of Petition 870250084217, dated 09 / 18 / 2025, page 29 / 50 22 / 23 a fastener assembly 102 comprising a locking pin 108 and a base frame 116, according to a fourth aspect of this description. The fastening system 100 is shown in a first assembled position. Figure 7B illustrates a cross-sectional view of the fastener assembly 102 taken along the cutting line EE in Figure 7A, and Figure 7C illustrates an exploded view of the fastener assembly 102 corresponding to Figures 7A and 7B.
[089] The fastener assembly 102 of Figures 7A to 7C is substantially the same as the fastener assembly 102 of Figures 4A to 4L, except for the mechanical interaction between the rod 152 and the fastening part 116B. Similar to the embodiment of Figures 6A to 6C, instead of positioning locking tabs on the base frame 116 to hold the locking pin 108 in place until the base frame 116 is inserted into the opening 106 of the first component 104, locking elements are formed on the locking pin 108 itself. For example, the locking pin 108 illustrated includes a locking tab 602 coupled to each flexible arm 402, the locking tab 602 being configured to engage the base frame 116 in order to secure the base frame 116 and the locking pin 108 in the transport position (Position A). As shown in the cross-sectional view of Figure 7B, the locking tab 602 attaches to the base frame 116 at or adjacent to the eyelet opening 138.
