Priority requirements

[0001] This patent application claims the rights of Chen et al. ， The priority interest is claimed in U.S. Provisional Patent Application Serial No. 63 / 548916, entitled “INTEGRATED RETAINER FOR TRIM TO FOAM ATTACHMENT”, filed on February 2, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] An integrated retainer for trims and foam attachments. Background Technology

[0003] In the field of vehicle manufacturing, the design and assembly of vehicle seats involves a variety of components and materials. The main component is the seat trim, which is the outermost layer of the seat that comes into direct contact with the occupants. Seat trim is typically made of materials such as leather or fabric, and its design aims to provide both comfort and aesthetics.

[0004] Seat trim pieces are attached to the foam vehicle seat body, which serves as structural support. The foam body is typically made of a resilient material capable of supporting the weight of occupants while providing a comfortable seating experience. It is usually molded to the desired shape of the seat and incorporates features such as contours and grooves to enhance comfort and ergonomics.

[0005] Attaching seat trim to the foam vehicle seat body is a process that requires precision and care. Traditionally, this is done using attachment mechanisms such as clamps, which are designed to securely hold the seat trim to the foam body for easy installation and removal. These clamps are typically made of durable materials such as plastic to withstand the stresses associated with vehicle seat use.

[0006] However, traditional attachment systems typically rely on receivers embedded within the foam seat body to secure these clips. This approach has several drawbacks. Embedding receivers increases manufacturing complexity, requiring precise alignment and attachment steps during production. It also increases costs due to the additional parts and labor involved. The fixed position of the receivers limits design flexibility, making it difficult to adjust or reposition seat trim without modifying the foam body. Over time, embedded receivers can wear or damage, leading to potential integrity issues with the seat trim attachments and making repairs difficult and expensive. Summary of the Invention

[0007] In one aspect, this disclosure relates to a vehicle seat trim retainer assembly including a flexible support rail and a plurality of spring-loaded clamps on the flexible support rail. Each of the plurality of spring-loaded clamps includes a first spring-loaded element and a second spring-loaded element. The first spring-loaded element has a first hook, a first rest position relative to the flexible support rail, and a first bent position relative to the flexible support rail. The second spring-loaded element has a second hook, a second rest position relative to the flexible support rail, and a second bent position relative to the flexible support rail. The first rest position and the second rest position are offset from each other to engage the first hook and the second hook with a vehicle seat body, and the first bent position and the second bent position are offset from each other to disengage the first hook and the second hook from the vehicle seat body.

[0008] In some examples of this, the first and second hooks protrude on opposite sides of the flexible support rail for engagement with the vehicle seat body.

[0009] In some examples of this, flexible support rails are made of soft materials for integration into seat trim, and multiple spring-loaded clamps are made of rigid materials for engagement with the vehicle seat body.

[0018] In some examples of this aspect, the first stationary position and the second stationary position are offset from each other to engage the first hook and the second hook with the foam vehicle seat body, and the first bent position and the second bent position are offset from each other to disengage the first hook and the second hook from the foam vehicle seat body.

[0019] In some examples of this, the opening in the foam vehicle seat body is positioned within a recess in the foam vehicle seat body.

[0020] In some examples of this, the opening in the foam vehicle seat body is a slit of length for accommodating two or more spring-loaded clamps among a plurality of spring-loaded clamps.

[0021] In some examples of this, flexible support rails are stitched into vehicle seat trim.

The following description of at least one example is merely illustrative and is in no way intended to limit this disclosure, its application, or its use. Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any specific values ​​should be interpreted as illustrative rather than limiting. Therefore, other examples may have different values. Note that similar reference numerals and letters refer to similar items in the following drawings, so once an item is defined in one drawing, further discussion may not be necessary for subsequent drawings. Examples will now be described with reference to the accompanying drawings.

[0038] To address the challenges associated with traditional seat trim attachment methods, a novel vehicle seat trim retainer assembly has been introduced. The assembly employs a series of spring-loaded clamps that are directly anchored to the foam of the vehicle seat body, eliminating the complexity and cost associated with embedding plastic receivers within the foam body.

[0039] The vehicle seat trim retainer assembly includes a flexible support rail and multiple spring-loaded clamps. The flexible support rail serves as a base for the spring-loaded clamps, providing a robust and adaptable structure that can be customized to the specific dimensions of the vehicle seat body. The flexibility of the support rail allows it to conform to the contours of the seat body, ensuring a safe and precise fit.

[0040] Each spring-loaded clamp on the flexible support rail is designed to engage directly with the foam vehicle seat body. These clamps consist of at least two spring-loaded elements, each with a hook. The spring-loaded elements are arranged in a scissor-like manner, allowing them to bend towards each other when inserted into the foam and spring away from each other when withdrawn from the back of the foam. This action enables the hook to engage with the back of the foam, providing a secure anchor point for the seat trim.

[0041] Spring-loaded clamps are designed to be inserted into slots within the foam body of the vehicle seat. These slots can be molded into the foam at desired locations, providing flexibility for the positioning of the seat trim. Once inserted, the hooks of the spring-loaded clamps engage with the back of the foam, holding the seat trim in place under tension and preventing the clamps from being pulled out of the foam.

[0042] Importantly, the spring-loaded clamp does not contain an actual spring. Instead, the spring-like action is achieved through the inherent flexibility of the rigid plastic component that forms the spring-loaded element. This design simplifies the clamp's construction, reduces manufacturing costs, and improves durability.

[0043] To remove the spring-loaded clamp from the foam, the clamp needs to be rotated approximately 90 degrees. This action disengages the hook from the foam, allowing the clamp to be pulled out. This feature facilitates easy removal and repositioning of seat trim, providing additional flexibility to the seat assembly process.

[0044] Reference Figure 1A The image shows a vehicle seat trim retainer assembly 100. Assembly 100 includes a flexible support rail 102 and a series of spring-loaded clamps, such as spring-loaded clamps 104A, 104B, and 104C formed on the flexible support rail 102. The flexible support rail 102 serves as a base for the spring-loaded clamps, providing a robust and adaptable structure that can be customized to the specific dimensions of the vehicle seat body. The flexibility of the support rail 102 allows it to conform to the contours of the seat body, ensuring a safe and precise fit.

[0045] These spring-loaded clamps, such as clamp 104A, are designed to engage directly with the foam vehicle seat body. In one example, the clamp is formed using two spring-loaded elements, each with a hook. The spring-loaded elements are arranged in a scissor-like manner, allowing them to bend toward each other when inserted into the foam and spring away from each other when withdrawn from the back of the foam. This action allows the hook to engage with the back of the foam, providing a secure anchor point for the seat trim.

[0046] In some cases, the flexible support rail 102 can be attached to the vehicle seat trim at a desired location, for example, by stitching. This configuration allows for precise positioning of the spring-loaded clamps on the seat trim, ensuring a safe and accurate fit when the seat trim is installed on the vehicle seat body. In particular, the flexible support rail 102 can be attached to the vehicle seat trim at a location corresponding to a recess in the vehicle seat body, for example, by stitching.

[0047] Turn Figure 1B The images show different perspective views of the vehicle seat trim retainer assembly 120. This assembly 120 also includes similar... Figure 1A The flexible support rail 122 is described herein. The flexible support rail 122 serves as a base for spring-loaded clamps, such as spring-loaded clamps 124A, 124B, and 124C. These clamps are systematically aligned and secured to the flexible support rail 122. This alignment and securing of the spring-loaded clamps to the flexible support rail 122 demonstrates the component's design, intended to anchor vehicle seat trim to the seat body with extremely high precision and order.

[0048] Each spring-loaded clamp, prominently protruding from the guide rail, is meticulously crafted to effectively grip the vehicle seat body, providing secure and reliable retention for the seat trim. The clamps and flexible guide rail can be molded simultaneously, or they can be molded separately, in which case the clamp is attached to the flexible guide rail. The spring-loaded clamps are designed to insert into slots within the foam vehicle seat body. These slots can be molded into the foam at desired locations, providing flexibility for the positioning of the seat trim. Once inserted, the hooks of the spring-loaded clamp engage with the back of the foam, holding the seat trim in place under tension and preventing the clamp from being pulled out of the foam.

[0049] In addition to the features described above, each spring-loaded clamp may optionally include retaining legs 126. These retaining legs 126 are designed to enhance the retaining force of the spring-loaded clamp within the foam vehicle seat body. When the spring-loaded clamp is inserted into the foam, the retaining legs 126 engage with the internal structure of the foam. This engagement increases the retaining force of the spring-loaded clamp, further securing the seat trim to the foam vehicle seat body. The retaining legs 126 provide an additional level of safety, ensuring that the spring-loaded clamp remains firmly anchored in the foam even under heavy use or stress conditions. This optional feature increases the versatility and effectiveness of the spring-loaded clamp.

[0050] Now refer to Figure 1C The image presents a detailed view 140 of a single spring-loaded clamp 142 from a vehicle seat trim retainer assembly. The spring-loaded clamp 142 consists of two rigid plastic components, specifically a first spring-loaded element 144 and a second spring-loaded element 146. These components are connected at a common base 147, which is part of or connected to a flexible support rail 148.

[0051] The first spring-loaded element 144 and the second spring-loaded element 146 are arranged side-by-side in a scissor-like manner. This arrangement allows the elements to bend inward toward the axis of the flexible support rail when inserted into the foam, and then spring away from the axis of the flexible support rail when withdrawn from the back of the foam. In other words, elements 144 and 146 have a natural resting state offset relative to the axis of the flexible support rail. This resting state can be overcome by the external force exerted by the foam when elements 144 and 146 are squeezed together in a bent position when inserted into a narrow foam groove. In other words, elements 144 and 146 can bend toward the axis of the flexible rail when squeezed through a narrow space such as a foam groove. However, after withdrawing from the back of the foam groove, elements 144 and 146 spring back to their natural offset resting state. This action allows the hook of the spring-loaded element to span a distance greater than the groove, thereby engaging with the back of the foam and providing a secure anchor point for the seat trim.

[0052] It is important to note that the spring-loaded element does not contain an actual spring. Instead, the spring-like action is achieved through the inherent flexibility of the rigid plastic component that forms the spring-loaded element. This design simplifies the construction of the clamp, reduces manufacturing costs, and improves durability.

[0053] Each spring-loaded element, namely the first spring-loaded element 144 and the second spring-loaded element 146, has heads 144A and 146A, hooks 144B and 146B, necks 144C and 146C, and bodies 144D and 146D. The head of each element is designed to insert into the foam vehicle seat body. The hook of each element is designed to engage with the back of the foam, providing a secure anchor point for the seat trim. The neck and body of each element provide structural support and facilitate scissor-like action of the spring-loaded clamp.

[0054] The spring-loaded clamp 142, consisting of a first spring-loaded element 144 and a second spring-loaded element 146, is also designed to be easily detached from the foam vehicle seat body when needed. This is achieved in one of two ways. If the first spring-loaded element 144 and the second spring-loaded element 146 are accessible, they can be squeezed together until they are no longer engaged with the foam and then pulled out through the foam groove. If the elements are inaccessible, a technician can rotate the spring-loaded clamp 142 approximately 90 degrees. This rotation causes the hooks of the spring-loaded elements to disengage from the foam, allowing the spring-loaded clamp 142 to be pulled out of the foam groove.

[0055] This feature of the spring-loaded clamp 142 provides practical advantages during seat assembly. It facilitates the easy insertion, removal, and repositioning of seat trim, offering additional flexibility during the seat assembly process. This is particularly beneficial when adjustments or modifications to the positioning of the seat trim are required, as it eliminates the complexity and potential damage associated with removing the embedded receiver from the foam vehicle seat body.

[0056] It is worth noting that the rotational action used to disengage the spring-loaded clamp 142 does not compromise the structural integrity or functionality of the clamp. The scissor-like arrangement of the spring-loaded elements (i.e., the first spring-loaded element 144 and the second spring-loaded element 146) allows them to retain their spring-like action even after repeated insertion and removal. This ensures that the spring-loaded clamp 142 can be reused multiple times, further enhancing the cost-effectiveness and durability of the vehicle seat trim retainer assembly.

[0057] Reference Figure 2AThe image depicts a front view of a vehicle seat 200. The vehicle seat 200 includes a seat back 202A, a headrest 202B, and a seat base 202C. These components constitute the main structure of the vehicle seat 200, providing support and comfort for the occupant. The seat back 202A and seat base 202C are typically made of foam material, which is molded into the desired shape to enhance comfort and ergonomics.

[0058] On the seat back 202A, multiple spring-loaded clamp insertion positions are marked. These insertion positions, specifically 204A, 204B, 204C, 204D, 204E, and 204F, are strategically positioned to align with contoured recesses in the foam into which the spring-loaded clamps of the vehicle seat trim retainer assembly will be inserted. These insertion positions are effectively designed to receive the spring-loaded clamps, providing secure anchoring points for the seat trim on the foam vehicle seat body.

[0059] Spring-loaded clamp insertion positions can be molded into the foam at desired locations (e.g., contoured grooves within the foam), providing flexibility for the positioning of seat trim. Once the spring-loaded clamps are inserted into these positions, the clamp hooks engage with the back of the foam, holding the seat trim in place under tension and preventing the clamps from being pulled out of the foam. This design simplifies the seat trim installation process, reduces manufacturing complexity and cost, while providing a safe and precise fit for seat trim on the vehicle seat body.

[0060] Turn Figure 2B This presents another view of the foam vehicle seat body 220. The foam vehicle seat body 220 includes a seat back 202A, which is typically constructed of foam material. The foam material is molded into a desired shape to enhance comfort and ergonomics. The seat back 202A is designed to provide support for the occupant's back, ensuring a comfortable seating experience.

[0061] On the seat back 202A, multiple spring-loaded clamp insertion positions are clearly marked. These insertion positions, specifically 204A, 204B, 204C, 204D, 204E, and 204F, are strategically positioned to align with the spring-loaded clamps of the vehicle seat trim retainer assembly. These insertion positions are designed to receive the spring-loaded clamps, providing a secure anchoring point for the seat trim on the foam vehicle seat body.

[0062] This design simplifies the installation process of seat trim, reduces manufacturing complexity and cost, while providing a secure and precise fit for the seat trim on the vehicle seat body. It also offers flexibility in seat trim positioning, as the slots can be molded into the foam at any desired location, allowing for adjustments or modifications to the seat trim positioning without the complexity and potential damage associated with removing the embedded receiver from the foam vehicle seat body.

[0063] Now for reference Figure 2C The image shows a top view of a seat trim piece with an integrated clip 240. The seat trim piece includes an inner surface 244 and an outer surface 242. The inner surface 244 is the side of the seat trim piece designed to attach to the foam vehicle seat body. The outer surface 242 is the side of the seat trim piece designed to be exposed to the vehicle seat occupants.

[0064] A series of spring-loaded clamps, including 248A, 248B, 248C, 248D, 248E, 248F, 248G, 248H, and 248I, are integrated into the inner surface 244 of the seat trim. These spring-loaded clamps are strategically positioned along the edge of the inner surface 244, conforming to the contour of the seat trim. For example, flexible guides can be stitched into the seat trim at locations corresponding to the contour of the seat trim. This strategic positioning of the spring-loaded clamps allows for a secure and precise fit when the seat trim is mounted on the vehicle seat body.

[0065] Each of the spring-loaded clamps 248A-248I is designed to engage with a corresponding slot (not shown) in the foam vehicle seat body. When the spring-loaded clamp is inserted into these slots, the hook of the clamp engages with the back of the foam, holding the seat trim in place under tension and preventing the clamp from being pulled out of the foam. This design simplifies the seat trim installation process, reduces manufacturing complexity and cost, while providing a secure and precise fit for the seat trim on the vehicle seat body.

[0066] In some cases, the spring-loaded clamps can be spaced at predetermined distances along the edge of the inner surface 244. This configuration allows for precise positioning of the spring-loaded clamps on the seat trim, ensuring a secure and accurate fit when the seat trim is installed on the vehicle seat body. It also provides flexibility in seat trim positioning, as the slots can be molded into the foam at any desired location, allowing for adjustments or modifications to the seat trim positioning without the complexities and potential damage associated with removing the embedded receiver from the foam vehicle seat body. The spacing of the spring-loaded clamps along the flexible guide can be uniform or non-uniform, depending on the application.

[0067] Turn Figure 2DThe image presents a rear view of the foam vehicle seat body 260. The foam vehicle seat body 260 has a series of aligned foam slots, such as foam slots 262, 266, and 270. These slots are strategically positioned to align with the spring-loaded clamps of the vehicle seat trim retainer assembly. Inserted into each of these slots is the corresponding spring-loaded clamp. Specifically, spring-loaded clamp 264 is engaged in foam slot 262, spring-loaded clamp 268 is engaged in foam slot 266, and spring-loaded clamp 272 is engaged in foam slot 270. Each of these spring-loaded clamps is designed to engage directly with the foam vehicle seat body. These clamps are formed using two spring-loaded elements, each with a hook. The spring-loaded elements are arranged in a scissor-like manner, allowing them to bend towards each other upon insertion into the foam and spring away from each other upon withdrawal from the back of the foam. This action allows the hooks of the spring-loaded elements to engage with the back of the foam, providing a secure anchor point for the seat trim.

[0068] Once the spring-loaded clamps are inserted into these slots, the hooks of the clamps engage with the back of the foam. This engagement holds the seat trim in place under tension and prevents the clamps from being pulled out of the foam. This design simplifies the seat trim installation process, reduces manufacturing complexity and cost, while providing a secure and precise fit for the seat trim on the vehicle seat body.

[0069] In some cases, the foam vehicle seat body 260 can be constructed, for example, by being molded with grooves in these desired locations, or by being molded without grooves and then having grooves cut out in the foam at the desired locations. This design allows for precise positioning of the spring-loaded clamps on the seat trim, ensuring a secure and accurate fit when the seat trim is installed on the vehicle seat body. It also provides flexibility in seat trim positioning, as the grooves can be molded into the foam at any desired location, allowing for adjustments or modifications to the seat trim positioning without the complexity and potential damage associated with removing the embedded receiver from the foam vehicle seat body.

[0070] Now for reference Figure 2E This image presents a close-up view of the back of foam 280. Foam 280 has a foam groove 282 into which a spring-loaded clamp 284 is inserted. The spring-loaded clamp 284 is designed to engage directly with the foam vehicle seat body. The clamp is formed by two spring-loaded elements, each with a hook. The spring-loaded elements are arranged in a scissor-like manner, allowing them to bend toward each other when inserted into the foam and spring away from each other when withdrawn from the back of the foam. This action allows the hooks of the spring-loaded elements to engage with the back of the foam, providing a secure anchor point for the seat trim. Once the spring-loaded clamp 284 is inserted into the foam groove 282, the hooks of the clamp engage with the back of the foam. This engagement holds the seat trim in place under tension and prevents the clamp from being pulled out of the foam.

[0071] Turn Figure 3 The flowchart 300 details the sequential steps for preparing and installing the vehicle seat trim. The process begins with the step of molding the vehicle seat trim retainer assembly, as shown in step 302. In this step, the vehicle seat trim retainer assembly, including flexible support rails and multiple spring-loaded clamps, is molded either as a single component or as separate components that are subsequently attached to each other (i.e., the clamps are attached to the rails). The vehicle seat trim retainer assembly can be molded to a length directly corresponding to the installation use case (i.e., the length of a particular seat), or it can be molded as a long roll that can be cut to the desired length by a technician.

[0072] Following the molding of the vehicle seat trim retainer assembly, the next step, as shown in step 304, involves forming grooves in the seat body where the vehicle seat trim retainer assembly is to be engaged. These grooves can be molded into the foam at desired locations or cut into the foam at desired locations, providing flexibility in seat trim positioning. In either case, once the grooves are formed, spring-loaded clamps of the vehicle seat trim retainer assembly can be inserted into these grooves, providing a secure anchor point for the seat trim on the foam vehicle seat body.

[0073] The next step in this process, as shown in step 306, is optional and involves cutting the support rail to the desired length of the vehicle seat. The flexible nature of the support rail allows it to be easily cut to the desired length, ensuring a precise fit when the seat trim is installed on the vehicle seat body. This step is not required if the support rail is molded to the desired length in step 302. Once the support rail has been cut to the desired length, the next step, as shown in step 308, involves attaching the support rail to the back of the seat trim. This can be achieved through various methods, such as stitching and bonding, providing a strong and robust connection between the seat trim and the support rail.

[0074] The next step in this process, as shown in step 310, involves mounting the seat trim onto the seat body by inserting the spring-loaded clamp of the seat trim retainer assembly into a recess in the seat body. Once the spring-loaded clamp is inserted into the recess, the hook of the clamp engages with the back of the foam, holding the seat trim in place under tension and preventing the clamp from being pulled out of the foam.

[0075] In addition to the steps outlined for installing seat trim using the vehicle seat trim retainer assembly, the installation process may include supplementary measures to ensure a secure and durable fit. One such measure may involve pinning the end of the seat trim to the back of the seat body. This step will provide additional reinforcement, preventing any potential slippage or movement of the seat trim over time. The pins will act as additional anchor points, supplementing the mechanical coupling provided by the spring-loaded clamps, and will be particularly useful in areas where the seat trim experiences high tension or stress during use. This method will further enhance the overall integrity and durability of the seat trim attachment to the foam vehicle seat body.

[0076] The design of the spring-loaded clamps in the vehicle seat trim retainer assembly is adjustable, allowing for various configurations to meet specific requirements. While the standard configuration includes two spring-loaded elements, clamps with more than two elements may be used to provide additional engagement points with the foam vehicle seat body. The bodies and hooks of these elements can also be varied in shape to optimize the mechanical coupling with the seat body, whether for enhanced grip, ease of insertion, or stress distribution. Furthermore, the materials used to manufacture the spring-loaded clamps can range from different types of plastics to metal alloys, depending on desired properties such as flexibility, strength, and durability. Material selection may also be influenced by factors such as weight considerations, cost constraints, and the specific environmental conditions the vehicle seat will be exposed to.

[0077] Furthermore, the recesses designed to accommodate the spring-loaded clamps of the vehicle seat trim retainer assembly can be integrated into the foam vehicle seat body in various ways. They can be channels within the foam body, providing concealed attachment points for the spring-loaded clamps. Alternatively, the recesses can be exposed on the back of the foam seat body, where they are easily accessible for insertion and engagement of the spring-loaded clamps. The choice between internal or exposed recesses can be determined by factors such as desired aesthetics, ease of assembly, or structural requirements of the seat design. Both configurations serve to securely anchor the seat trim to the foam body while allowing flexibility in the trim's positioning and adjustment.
