Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a covering mechanism for ISOFIX connectors in automotive seats. Background Technology

[0002] To facilitate the installation of child seats in car seats, car seats (usually rear seats) typically have pre-drilled ISOFIX connectors for installation. Figure 1 and Figure 2 As shown in the figure, a rear double seat is provided, in which each seat is provided with two ISOFIX ports 4, and all ISOFIX ports 4 are arranged at intervals along the extension direction of the seat back gap (i.e., the gap between the bottom of the backrest 1 and the top of the seat cushion 2).

[0003] To ensure the aesthetics of car seats, a cover curtain 32 is typically used to cover each ISOFIX connector 4. Existing cover curtains 32 are usually installed one cover curtain 32 per seat, simultaneously covering all ISOFIX connectors 4 on that seat. This cover curtain 32 has an up-and-down flip-up structure, in conjunction with… Figure 1 and Figure 2 As shown, the first end of the cover curtain 32 is rotatably connected above the corresponding ISOFIX socket 4, and the rotation axis L1 is parallel to the extension direction of the seat / backrest gap. The cover curtain 32 achieves simultaneous blocking and opening of all corresponding ISOFIX sockets 4 through its up-and-down rotation movement. Figure 1 This shows the state where the cover curtain 32 simultaneously blocks the corresponding ISOFIX port 4. Figure 2 The diagram shows the state where the cover curtain 32 is simultaneously open, corresponding to the ISOFIX connector 4. It is clear from the diagram that when the ISOFIX connector 4 is needed and the cover curtain 32 is open, an angle is formed between the cover curtain 32 and the seat cushion 2, preventing the ISOFIX connector 4 from being fully exposed. This makes it easy to misalign the ISOFIX connector 4 during child seat installation, requiring repeated attempts. Furthermore, the end of the cover curtain 32 is not fixed, requiring manual assistance to secure it during installation to keep the ISOFIX connector 4 exposed, further complicating the installation process. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a covering mechanism for ISOFIX connectors in car seats, resolving problems such as the small opening angle of existing flip-up cover curtains and difficulties in installing child seats.

[0005] This utility model is achieved through the following solution: a covering mechanism for ISOFIX connectors in automotive seats, comprising a fixing member and a covering curtain, wherein the number of the fixing member and the covering curtain are the same as the number of ISOFIX connectors, and their positions correspond one-to-one. The covering curtain is pivotally connected to the corresponding fixing member about a pivot axis; wherein: the fixing member is fixed to the automotive seat, and the pivoting of the covering curtain allows the covering curtain to switch between an open state exposing the ISOFIX connectors and a closed state covering the ISOFIX connectors; when the covering curtain is in the open state, the pivot axis is perpendicular to the covering curtain.

[0006] A further improvement of this utility model is that it includes a pivot shaft that provides a pivot axis, one of the cover curtain and the fastener is provided with a pivot hole and is pivotally connected to the pivot shaft through the pivot hole; the other of the cover curtain and the fastener is fixedly connected to the pivot shaft.

[0007] A further improvement of this utility model is that the cover curtain includes a first end with the pivot shaft or the pivot hole and a second end for covering the corresponding ISOFIX port; when the cover curtain is in the open state, the first end and the second end are coplanar; when the cover curtain is in the closed state, the first end and the second end are not coplanar.

[0008] A further improvement of this utility model is that a first docking member is fixed to the second end of the cover curtain, and a second docking member is fixed to each ISOFIX port on the car seat for the corresponding first docking member to dock with when the cover curtain is closed.

[0009] A further improvement of this utility model is that the first docking member and the second docking member are detachably connected by magnetic attraction or by snap-fit.

[0010] A further improvement of this invention is that the covering curtain includes a flexible plate that can switch between a straight state where the first end and the second end are coplanar and a curved state where the first end and the second end are not coplanar.

[0011] A further improvement of this utility model is that the covering curtain further includes an upper covering layer and a lower covering layer respectively stacked on the upper and lower surfaces of the flexible plate. The pivot shaft includes a column section that rotatably engages with the pivot hole, and a first limiting part disposed at one end of the column section. The first limiting part is engaged between the upper covering layer and the flexible plate to limit the axial displacement of the covering curtain relative to the pivot shaft. The pivot hole includes a first hole disposed on the flexible plate for the column section to pass through, and a second hole disposed on the lower covering layer for the column section to pass through.

[0012] A further improvement of this utility model is that the first hole is an oblong hole, and the length of the first hole is between the diameter of the column section and the diameter of the first limiting part, and the width of the first hole is greater than the diameter of the column section and the difference does not exceed 1mm.

[0013] A further improvement of this utility model is that the pivot shaft and the pivot hole are disposed in the seat-back gap area. When the cover curtain is in the open state, the cover curtain is at least partially embedded in the seat-back gap. When the cover curtain is in the closed state, the first end is embedded in the seat-back gap and the second end is sealed to the corresponding ISOFIX port.

[0014] A further improvement of this utility model is that the fixing member includes an edge disposed around the outer periphery of the corresponding ISOFIX socket, the edge including a first edge having a pivot shaft or pivot hole at the corresponding first end, a second edge disposed opposite to the first edge, and a third edge connecting the first edge and the second edge; the second mating member is disposed on the second edge and / or the third edge.

[0015] A further improvement of this utility model is that the fixing member includes a fixing plate with a pivot shaft or pivot hole, and the fixing plate is disposed on the seat cushion or backrest in the seat-back gap area.

[0016] A further improvement of this utility model is that the cover curtain includes a first end with the pivot shaft or pivot hole and a second end for covering the corresponding ISOFIX connector. The fastener is disposed on the front of the backrest. When the cover curtain is in the open state, the first end and the second end are coplanar and the cover curtain is attached to the front of the backrest. When the cover curtain is in the closed state, the first end and the second end are coplanar and the cover curtain covers the corresponding ISOFIX connector.

[0017] This invention, by adjusting the direction of the pivot axis, allows the cover curtain to be attached to the front of the backrest or embedded in the seat gap when it is open, thereby fully exposing the ISOFIX connectors. It does not require manual assistance to fix, solving the problems of small opening angle and difficulty in installing child seats in existing flip-up cover curtains. Attached Figure Description

[0043] To address the problems of limited opening angle and difficulty in installing child seats caused by existing flip-up blinds, this invention provides a covering mechanism for ISOFIX connectors in car seats. This mechanism ensures that the ISOFIX connectors are fully exposed when the blind is open, and requires no manual assistance for securing the seat, making child seat installation much easier. The following detailed description, in conjunction with the accompanying drawings, further illustrates this covering mechanism for ISOFIX connectors in car seats.

[0044] See Figures 3 to 15 As shown, a covering mechanism for ISOFIX connectors in automotive seats includes a fastener 31 and a covering curtain 32. The number of fasteners 31 and the covering curtain 32 are the same as the number of ISOFIX connectors 4, and their positions correspond one-to-one. Figure 3In the illustrated double-row seat, four ISOFIX connectors are spaced apart along the extension direction of the seat back gap (i.e., the gap between the bottom of the backrest 1 and the top of the seat cushion 2) (i.e., the extension direction of the existing flip-up curtain axis L1). Each ISOFIX connector is covered by a curtain 32. Each curtain 32 is pivotally connected to a corresponding fastener 31 about a pivot axis L2. Specifically, the fastener 31 is fixed to the car seat, and the pivoting of the curtain 32 allows it to switch between an open state exposing the ISOFIX connectors 4 and a closed state concealing them. When the curtain 32 is open, the pivot axis L2 is perpendicular to the curtain 32. This differs from existing flip-up curtains, which are parallel to the flip axis L1 when open. The aforementioned ISOFIX connector covering mechanism innovatively adjusts the pivot axis L2 of the covering curtain 32, changing the pivot axis L2 from being parallel to the covering curtain 32 to being perpendicular to the covering curtain 32. This allows the ISOFIX connector 4 to be fully exposed when the covering curtain 32 is in the open state, solving the problems of small opening angle and difficulty in installing child seats in existing flip-up covering curtains.

[0045] The pivotal connection between the curtain 32 and the fastener 31 can be achieved through a pivotal connection of a shaft and a hole. Specifically, the covering mechanism includes a pivot shaft 321 providing a pivot axis L2. One of the curtain 32 and the fastener 31 has a pivot hole and is pivotally connected to the pivot shaft 321 through this pivot hole. The other of the curtain 32 and the fastener 31 is fixedly connected to the pivot shaft 321. This fixed connection can also be interpreted as being integrally formed. The specific mating structure will now be described in detail through several embodiments:

[0046] First embodiment, see reference Figures 4 to 10 As shown, the curtain 32 is rectangular, including two ends arranged opposite each other along its length, namely a first end and a second end. The first end has a pivot hole for pivotal connection of the pivot shaft 321. The second end is used to cover the corresponding ISOFIX connector 4. The fastener 31 has a through hole 311 fixed on it, and is fixedly connected to the pivot shaft 321 through the through hole 311 (this can be achieved by adhesive, snap-fit, or threaded connection, etc.). The pivotal connection between the curtain 32 and the corresponding fastener 31 is achieved by the rotational engagement of the pivot shaft 321 and the pivot hole. In some other embodiments, the pivot shaft 321 can also be fixed to the curtain 32, and the pivot hole can be fixed to the fastener 31, depending on the actual situation. In this embodiment, the pivot shaft 321 and the pivot hole are rotatably engaged within the seat gap area. This ensures that the first end and the second end do not remain coplanar during the switching between the open and closed states of the curtain 32.

[0047] Specifically, such as Figures 4-6 As shown, Figures 4-6 As shown in Figure (a), the blind 32 is in the closed state. At this time, the first and second ends of the blind 32 are not coplanar, the blind 32 is curved overall, and the first end is embedded in the seat / backrest gap, while the second end is sealed to the corresponding ISOFIX connector 4. Figures 4-6 As shown in Figure (c), the curtain 32 is in the open state. At this time, the first and second ends of the curtain 32 are coplanar, and the curtain 32 is generally straight and at least partially embedded in the seat gap. To allow the curtain 32 to switch between the open and closed states, the curtain 32 includes a flexible plate 323. This flexible plate 323 can switch between a straight state where the first and second ends are coplanar and a bent state where the first and second ends are not coplanar. Specifically, the flexible plate 323 can be made of plastic materials such as PP, PE, or PC. The original state of the flexible plate 323 is straight, while the bent state requires overcoming a certain external force to maintain. To ensure that the flexible plate 323 can maintain its bent state when the curtain 32 is closed, docking components that can dock with each other at the second end of the curtain 32 and corresponding positions on the car seat when the curtain 32 is closed can be provided. When the cover curtain 32 needs to be switched from the closed state to the open state, external force needs to be manually applied first to disengage the docking components, and the cover curtain 32 needs to be in the following position: Figures 4-6 As shown in Figure (b), in the intermediate state, the first end of the cover curtain 32 remains embedded in the seat back gap, and the second end is folded upwards to be coplanar with the first end. The cover curtain 32 is in a flat state, and the corresponding ISOFIX connector 4 is open. Although the ISOFIX connector 4 is open, it cannot be used in this state because the second end of the cover curtain 32 extends out of the front of the backrest 1, occupying the installation space of the child seat. It is not a truly open state. The cover curtain 32 needs to be further rotated left / right to finally be retracted into the seat back gap. At this point, the cover curtain 32 is in the position shown in Figure (b). Figures 4-6 The open state is shown in Figure (c). Using this embodiment, when the ISOFIX connector 4 is needed, the cover 32 can be hidden and stored within the seat / backrest gap, fully exposing the ISOFIX connector 4 while maintaining a good appearance.

[0048] In this embodiment, the fastener 31 includes an edge surrounding the outer periphery of the ISOFIX connector 4. Specifically, the edge includes a first edge 312 with a pivot shaft 321 fixed to its first end (if a pivot shaft is fixed to the first end, a pivot hole is provided therein), a second edge 313 arranged opposite to the first edge 312, and a third edge 314 connecting the first edge 312 and the second edge 313. These edges together form a cover fitted over the ISOFIX connector 4, providing space for the through hole 311 and preventing the ISOFIX connector 4 from being directly exposed, thus achieving a concealing effect.

[0049] For details regarding the rotational fit between the pivot shaft 321 and the pivot hole, please refer to [link / reference needed]. Figures 16-24As shown, the covering curtain 32 further comprises an upper covering layer 322 and a lower covering layer 324 which are respectively stacked on the upper surface and the lower surface of the flexible plate 323. The arrangement of the upper covering layer 322 and the lower covering layer 324 can improve the appearance effect of the covering curtain 32. The pivoting shaft 321 comprises a cylindrical body section 3211 rotatably fitted with the pivoting hole, and a first limiting portion 3212 arranged at one end of the cylindrical body section 3211, the first limiting portion 3212 is clamped between the upper covering layer 322 and the flexible plate 323 to limit the axial displacement of the covering curtain 32 relative to the pivoting shaft 321. The pivoting hole comprises a first hole 3231 opened on the flexible plate 323 for the cylindrical body section 3211 to pass through, and a second hole 3241 opened on the lower covering layer 324 for the cylindrical body section 3211 to pass through. Wherein, the diameter of the cylindrical body section 3211 is set as d2, and the diameter of the first limiting portion 3212 is set as d1. In order to ensure that the covering curtain 32 has a moving amount for left-right rotation and the pivoting shaft 321 does not fall out, the first hole 3231 is a slotted hole, and the length d4 of the first hole 3231 satisfies: d2<d4<d1. Further, in order to ensure that the covering curtain 32 does not move up and down and the pivoting shaft 321 moves smoothly, the width d5 of the first hole 3231 is slightly larger than the diameter d2 of the cylindrical body section of the pivoting shaft 321, the difference between the two is determined according to actual conditions. In this embodiment, the width d5 satisfies: d2<d5<d2+1mm. In order to ensure that the cylindrical body section 3211 of the pivoting shaft 321 can smoothly pass through the lower covering layer 324, and be accurately installed on the through hole 311 without shaking up, down, left and right, the diameter D1 of the second hole 3241 opened on the lower covering layer 324 is substantially equal to the diameter d2 of the cylindrical body section 3211. Regarding the fixed connection between the pivoting shaft 321 and the through hole 311, the diameter of the through hole 311 is adapted to the diameter of the cylindrical body section 3211, and the two are fixedly connected, so that during the pivoting of the covering curtain 32, no relative rotation occurs between the pivoting shaft 321 and the fixing member 31. Preferably, a second limiting portion 3213 is further arranged on the other end of the cylindrical body section 3211, the diameter of the second limiting portion 3213 is set as d3 which is larger than the diameter d2 of the cylindrical body section 3211, so that the second limiting portion 3213 can be clamped below the through hole 311 (that is, the side facing away from the covering curtain 32), such as Figure 23 and Figure 24As shown. To improve stability, it is preferable that the second limiting part 3213 is provided in multiple axial directions along the column section 3211. When the first end of the cover curtain 32 is fixed with the pivot shaft 321 and the fixing member 31 is provided with a pivot hole, the through hole 311 can be directly used as a pivot hole, so that it can be pivotally connected to the column section 3211 of the pivot shaft 321. The second limiting part 3213 blocks the axial displacement between the pivot shaft 321 and the fixing member 31 by blocking below the through hole 311. The pivot shaft 321 and the first end of the cover curtain 32 are fixedly connected. Specifically, the first limiting part 3212 can be used to fix the cover curtain 32 and the pivot shaft 321 relative to each other by clamping or bonding.

[0050] Preferably, a first connecting member 51 is fixed to the second end of the cover curtain 32. A second connecting member 52 is fixed to each ISOFIX connector 4 below the center on the car seat, for engaging with the first connecting member 51 when the cover curtain 32 is closed. The first connecting member 51 and the second connecting member 52 together form the aforementioned connecting assembly. Specifically, the first connecting member 51 and the second connecting member 52 can be detachably connected by magnetic attraction, such as a combination of dissimilar magnetic sheets or a combination of magnetic sheets and metal sheets, or they can be detachably connected by snap fasteners, including male and female snap fasteners, such as Velcro or button combinations. By providing the first connecting member 51 and the second connecting member 52, the second end of the cover curtain 32 can be fixed relative to the car seat when it is closed, ensuring that the cover curtain 32 stably blocks the ISOFIX connectors 4. When it is necessary to open the ISOFIX connectors 4, the first connecting member 51 and the second connecting member 52 can be disengaged.

[0051] In this embodiment, as Figures 7-10 As shown, the first mating part 51 is a metal sheet, fixed to area B of the cover curtain 32, specifically, in conjunction with... Figure 19As shown, the cover curtain 32 also includes a pocket fabric 325, which is sewn onto the back of the lower covering layer 324 to form a pocket for accommodating the first connecting member 51. By sealing the first connecting member 51, its exposure is prevented, ensuring the aesthetic appearance of the cover curtain 32. The manufacturing steps of the cover curtain 32 are as follows: First, the pivot shaft 321 is passed through the first hole 3231 of the flexible plate 323. Then, both are placed together on the back of the upper covering layer 322. Adhesive is applied to the four edges of the upper covering layer 322, and the flexible plate 323 is folded to secure it, thus forming the front assembly. Then, the pocket fabric 325 is sewn on three sides to area B on the back of the lower covering layer 324 to form an open pocket. The first connecting member 51 is then placed inside the pocket, and the pocket is then sewn closed. Adhesive is applied to the four edges of the lower covering layer 324, and the edges are folded to form the back assembly. Finally, the front assembly and the back assembly are placed side-by-side, and decorative stitching is sewn around the edges to combine them into a complete cover curtain 32. The above-mentioned folding action effectively hides the raw edges of the fabric, improving the appearance of the cover curtain 32. Of course, besides using the aforementioned sash method to fix the first connecting piece 51, it can also be fixed directly to the back of the lower covering layer 324 using adhesive or other fixing methods. Regarding the second connecting piece 52, it is specifically divided into two parts. These two parts are symmetrically fixed (using adhesive or snap-fit ​​methods) to the upper or lower surfaces of the two third edges 314 (preferably fixed to the lower surface so that the second connecting piece 52 can be hidden below the edges for a better appearance), and their positions correspond to the first connecting piece 51. This allows the two ends of the second connecting piece 52 to attract the two parts of the first connecting piece 51 when the second end of the cover curtain 32 blocks the ISOFIX connector 4. Of course, the second connecting member 52 can also be fixed as a whole to the upper or lower surface of the second edge 313 (preferably the lower surface), or the second connecting member 52 can be divided into three parts and fixed to the second edge 313 and the two third edges 314 respectively. In any arrangement, it should be ensured that the second connecting member 52 can be stably connected to the first connecting member 51 when the cover curtain 32 is in the closed state.

[0052] Second embodiment, see Figure 4 , Figure 5 , Figure 11 and Figure 12As shown, this embodiment differs from the first embodiment in that the fixing member 31 in this embodiment is a fixing plate with a pivot shaft 321. A through hole 311 is provided on the fixing plate, through which the pivot shaft 321 passes and is fixed. This fixing member 31 is placed on the seat cushion 2 or at the bottom of the backrest 1 within the seat-back gap area, allowing the pivot shaft 321 to rotate and engage with the pivot hole within the seat-back gap area. In this embodiment, to avoid direct exposure of the ISOFIX connectors 4, the cover of the seat cushion 2 is extended to the periphery of each ISOFIX connector 4, thereby achieving a concealing effect. Furthermore, in this embodiment, the first mating member 51 and the second mating member 52 use a Velcro combination. Specifically, one of the first mating member 51 and the second mating member 52 has a barbed surface, and the other has a rough surface; both are fixed by stitching. Regarding their arrangement, as... Figure 11 As shown, the first mating member 51 is sewn along the width direction of the cover curtain 32 to the second end of the cover curtain 32, and the second mating member 52 is sewn along the width direction of the corresponding ISOFIX socket 4 below the ISOFIX socket 4. When the cover curtain 32 is in the closed state, the first mating member 51 and the second mating member 52 are glued together. For example... Figure 12 As shown, the first connecting piece 51 is divided into two parts, and the two parts are symmetrically sewn to opposite sides of the second end of the cover curtain 32. The second connecting piece 52 is also divided into two parts, and the two parts are symmetrically sewn to opposite sides of the lower part of the corresponding ISOFIX connector 4. When the cover curtain 32 is in the closed state, the two parts of the first connecting piece 51 are respectively glued to the two parts of the second connecting piece 52. In some embodiments, the above-mentioned Velcro combination can also be replaced with other fastening combinations, or with a magnetic combination as in the first embodiment, etc.

[0053] Third embodiment, see Figures 13-15 As shown, the fixing member 31 in this embodiment also uses a fixing plate, but the difference compared to the second embodiment is that in this embodiment, the fixing member 31 is fixed to the front of the backrest 1 and adjacent to the seat cushion 2, so that the pivot shaft 321 and the pivot hole are rotatably engaged with the front of the backrest 1, thereby allowing the first end and the second end of the cover curtain 32 to remain coplanar during the switching between the open and closed states. Specifically, Figure 13 The cover 32 shown is in the closed state. At this time, the first and second ends are coplanar and together seal the corresponding ISOFIX socket 4 in a naturally drooping state. Figure 14 and Figure 15 Two open states of the blind 32 are shown. In both open states, the first and second ends of the blind 32 remain coplanar, and the blind 32 is attached to the front of the backrest 1. Only in... Figure 14In the open state, the cover curtain 32 is horizontally attached to the front of the backrest 1, while... Figure 15 In the open position, the cover curtain 32 is vertically attached to the front of the backrest 1. Besides Figure 14 and Figure 15 In addition to the two open states shown, the cover curtain 32 can also be in other open states, as long as the corresponding ISOFIX socket 4 is fully exposed.

[0054] In this embodiment, the pivot shaft 321 and the pivot hole are interference-fitted, so that the pivot hole will only rotate relative to the pivot shaft 321 when a certain external force is applied. This allows the cover curtain 32 to be held in any rotational position, ensuring that the cover curtain 32 remains closed when the ISOFIX connector 4 is not used. When the ISOFIX connector 4 is used, the cover curtain 32 is held against the front of the backrest 1, allowing the ISOFIX connector 4 to be fully exposed and open. This avoids the need for manual support to secure the cover curtain 32 during child seat installation, making installation more convenient and allowing for single-person operation. Of course, to ensure that the curtain 32 can be stably attached to the backrest 1 when it is open, a docking component can also be provided. Unlike the second embodiment, this docking component includes a first docking member and a third docking member. The installation position of the first docking member can be the same as that of the first docking member 51 in the second embodiment. The third docking member is installed on the front of the backrest 1 and at the position corresponding to the first docking member, so as to dock with the first docking member when the curtain 32 is open. Preferably, in order to ensure that the curtain 32 can stably block the ISOFIX connector 4, in this embodiment, the second docking member 52 can also be retained as in the first or second embodiment. When the curtain 32 is closed, the first docking member docks with the second docking member, and when the curtain 32 is open, the first docking member docks with the third docking member. The docking can be released under a certain external force. Regarding the cooperation between the first and second docking parts, as well as the cooperation between the first and third docking parts, a magnetic combination as in the first embodiment, a Velcro combination as in the second embodiment, or other fastening combinations can be used, which will not be elaborated here.

[0055] In summary, this invention, by adjusting the direction of the pivot axis, allows the cover curtain to be attached to the front of the backrest or embedded in the seat gap when it is open, thereby fully exposing the ISOFIX connectors without the need for manual assistance in fixing it.
