Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a leg support support strip and leg support for automotive seats. Background Technology

[0002] Many car seats have a retractable leg rest at the bottom, near the front of the seat cushion. This leg rest supports the passenger's lower legs, improving passenger comfort. In addition, the leg rest is retractable and adjustable to accommodate passengers of different heights and body types.

[0003] Existing car seat leg support structures mainly consist of a frame, foam components, and a cover. The foam components are mounted on the frame, and the cover covers them. Because the foam components are not fixed to the frame, after the cover is placed over them, the upper part of the cover lacks rigid support. Under the tensile force of the cover, the foam components are prone to separating from the frame and shifting, resulting in uneven gaps between the foam components and the plastic parts on the leg support. Furthermore, the stitching at the upper end of the leg support is not straight, leading to uneven gaps between it and the seat cushion. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a leg support strip and leg support for car seats that can solve the problem of movement of foam parts on the leg support and improve the appearance of the leg support.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a leg support cover support strip for automobile seats. The leg support includes a frame, a foam component, and a cover. The foam component is disposed on the frame, and the cover covers the foam component.

[0006] One end of the support strip is provided with a fixing buckle, and the other end of the support strip is provided with a straight support part. The support strip is fastened to the skeleton by the fixing buckle, and the straight support part extends toward the foaming part and is arranged along the edge of the foaming part.

[0007] After the cover is wrapped around the foam, the straight support portion supports the cover at the edge of the foam.

[0008] Furthermore, the foamed component has a first edge and a second edge that are disposed opposite to each other along the thickness direction of the leg support;

[0009] A support plate is connected to the straight support part, the straight support part supports the faceplate at the first edge, and the support plate supports the faceplate at the second edge.

[0010] Furthermore, the edge of the support plate away from the straight support portion is arranged parallel to the straight support portion.

[0011] Furthermore, the cross-section of the support plate is arc-shaped.

[0012] Furthermore, the thickness of the support plate is less than the thickness of the support strip;

[0013] The thickness at the connection between the support plate and the flat support portion is less than the thickness of the support plate, and the support plate can be folded relative to the flat support portion.

[0014] Furthermore, the fixing buckle includes a first locking part and a second locking part arranged opposite to each other, and the first locking part and the second locking part can be respectively locked onto both sides of the frame.

[0015] Furthermore, the first snap-fit ​​portion protrudes towards the side closer to the second snap-fit ​​portion with anti-detachment barbs, and the second snap-fit ​​portion protrudes towards the side closer to the first snap-fit ​​portion with anti-detachment barbs.

[0016] Furthermore, the second snap-fit ​​portion is formed by bending from the first snap-fit ​​portion, and has a snap-fit ​​guide on the second snap-fit ​​portion, the snap-fit ​​guide gradually approaching the first snap-fit ​​portion from one end to the other end;

[0017] Multiple fixing buckles are provided at intervals along the length of the support strip.

[0018] Furthermore, the support strip is provided with a plurality of reinforcing ribs along the side away from the fixing buckle, and the reinforcing ribs are arranged along the length direction of the support strip.

[0019] The technical solution adopted by this utility model to solve its technical problem is to also propose a leg support, on which the above-mentioned support strip is configured.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In this invention, the support strip is fixed to the frame by a fixing buckle, and its straight support part extends towards the foam part and is arranged along the edge of the foam part. It can support the cover at the edge of the foam part, provide rigid support for the cover at the edge, and block the transmission of the covering and pulling force of the cover to the foam part, so as to prevent the foam part from separating from the frame. It can effectively solve the problem of the foam part easily moving, and can also improve the problem of uneven matching gap between the cover and the plastic part.

[0022] In this invention, in the support strip with a support plate, the support end and the support plate can respectively support the faceplate at the first edge and the second edge of the foam, ensuring that the faceplate edges at these two points are straight, which can effectively improve the appearance.

[0023] In this utility model, the fixing buckle includes a first locking part and a second locking part. Both the first locking part and the second locking part are provided with anti-loosening barbs to ensure reliable fixing and good stability of the support strip and the skeleton.

[0042] Example 1:

[0043] like Figures 1-6 As shown in the figure, the leg support cover support strip 1 for a car seat in this embodiment includes a frame 2, a foam component 3, and a cover (not shown). The foam component 3 is disposed on the frame 2, and the cover covers the foam component 3. A fixing buckle 11 is provided at one end of the support strip 1, and a straight support portion 12 is provided at the other end of the support strip 1. The support strip 1 is fastened to the frame 2 by the fixing buckle 11, and the straight support portion 12 extends toward the foam component 3 and is arranged along the edge of the foam component 3. After the cover covers the foam component 3, the straight support portion 12 supports the cover at the edge of the foam component 3.

[0044] In actual use, the support strip 1 of this embodiment is fixed to the frame 2 by the fixing buckle 11, and its straight support part 12 extends towards the foam 3 and is arranged along the edge of the foam 3. It can support the cover at the edge of the foam 3, provide rigid support for the cover at the edge, and block the transmission of the cover covering pulling force to the foam 3, so as to prevent the foam 3 from separating from the frame 2. It can effectively solve the problem that the foam 3 is easy to move, and can improve the problem of uneven matching gap between the cover and the plastic part.

[0045] The end of the straight support portion 12 is a straight edge, which provides rigid support for the cover at the upper edge of the foam 3, and forms a straight ridge on the cover at that point, improving the aesthetics and refinement of the leg rest. Furthermore, by adding the support strip 1 of this embodiment to the upper end of the leg rest, the problem of uneven gap between the leg rest and the seat cushion can be improved, enhancing the overall appearance. This solves the process bottleneck of not being able to place the supporting PE sheet due to the foam being too thin.

[0046] like Figures 3-6 As shown, in the support strip 1 of this embodiment, the fixing buckle 11 includes a first engaging part 111 and a second engaging part 112 arranged opposite to each other. The first engaging part 111 and the second engaging part 112 can be respectively engaged on both sides of the frame 2. Specifically, the frame 2 is provided with a through groove corresponding to the fixing buckle 11, and the first engaging part 111 and the second engaging part 112 of the fixing buckle 11 are respectively engaged to both sides of the frame 2 from the through groove.

[0047] Multiple fixing buckles 11 are spaced apart along the length of the support strip 1. Correspondingly, multiple fixing buckles 11 are provided in the frame 2 with corresponding through slots. The multiple fixing buckles 11 are engaged with the frame 2 to ensure the fixing effect of the support strip 1 on the frame 2.

[0048] Furthermore, the second snap-fit ​​portion 112 is formed by bending from the first snap-fit ​​portion 111, creating a gap between the second snap-fit ​​portion 112 and the first snap-fit ​​portion 111. The support strip 1 can be integrally injection molded. The second snap-fit ​​portion 112 has a snap-fit ​​guide head 112A, which gradually approaches the first snap-fit ​​portion 111 from one end to the other. When assembling the support strip 1 onto the frame 2, the snap-fit ​​guide head 112A provides guidance during assembly, eliminating the need for precise alignment and facilitating assembly. Furthermore, if it is necessary to remove the support strip 1 later, the snap-fit ​​guide head 112A can be used as a force application point, allowing it to be pried outwards and detached from the frame 2.

[0049] Furthermore, the first snap-fit ​​portion 111 protrudes towards the side near the second snap-fit ​​portion 112 with an anti-detachment barb 113, and the second snap-fit ​​portion 112 protrudes towards the side near the first snap-fit ​​portion 111 with an anti-detachment barb 113. The anti-detachment barbs 113 on the first snap-fit ​​portion 111 and the barbs on the second snap-fit ​​portion 112 are symmetrically arranged. The anti-detachment barb 113 has an outwardly convex arc surface and an inwardly concave arc surface. The outwardly convex arc surface can be easily snapped into place when assembled with the frame 2, and the inwardly concave arc surface can further improve the anti-detachment effect. A folded edge is provided at the through groove of the frame 2. This folded edge can be adapted to the anti-loosening barb 113. After the fixing buckle 11 is engaged with the frame 2, the anti-loosening barb 113 abuts against the folded edge. When the fixing buckle 11 moves downward from the frame 2, the anti-loosening barb 113 abuts against the folded edge, forming interference, so that the fixing buckle 11 cannot be disengaged from the frame 2, ensuring a good engagement and fixing effect of the fixing buckle 11.

[0050] In actual use, the fixing buckle 11 of the support strip 1 in this embodiment includes a first locking part 111 and a second locking part 112. Both the first locking part 111 and the second locking part 112 are provided with anti-loosening barbs 113 to ensure that the support strip 1 and the skeleton 2 are reliably fixed and have good stability.

[0051] Preferably, the support strip 1 is provided with a plurality of reinforcing ribs 14 along the side away from the fixing buckle 11. The reinforcing ribs 14 are arranged along the length direction of the support strip 1 to avoid the formation of a large flat surface on the support strip 1, which is prone to deformation during molding and use. The setting of the reinforcing ribs 14 can prevent deformation and increase its strength.

[0052] Example 2:

[0053] like Figures 7-9 and combined Figure 2As shown, this embodiment is an optimization of the support strip 1 in Embodiment 1. A support plate 13 is added to the support end of the support strip 1 in Embodiment 1, while the other structures are the same as in Embodiment 1. Similarly, a fixing buckle 11 is provided at one end of the support strip 1, and a straight support portion 12 is provided at the other end. The support strip 1 is fastened to the frame 2 by the fixing buckle 11, and the straight support portion 12 extends towards the foam component 3, arranged along the edge of the foam component 3. After the cover is applied to the foam component 3, the straight support portion 12 supports the cover at the edge of the foam component 3. Specifically, the foam component 3 has a first edge 31 and a second edge 32 arranged opposite to each other along the thickness direction of the leg support, i.e., the first edge 31 and the second edge 32 are located on the inner and outer sides of the upper end of the leg support, respectively. In this embodiment, a support plate 13 is connected to the straight support part 12. The straight support part 12 supports the cover at the first edge 31, and the support plate 13 supports the cover at the second edge 32, ensuring that the cover at the first edge 31 and the cover at the second edge 32 both form a straight ridge line, which can improve the aesthetics and refinement of the leg rest.

[0054] Among them, the edge of the support plate 13 away from the straight support part 12 is arranged parallel to the straight support part 12. After the support plate 13 and the straight support part 12 support the faceplate at the first edge 31 and the faceplate at the second edge 32, the two edges formed are also parallel.

[0055] The cross-section of the support plate 13 is arc-shaped. The thickness of the support plate 13 is less than the thickness of the support strip 1. The thickness at the connection between the support plate 13 and the straight support part 12 is less than the thickness of the support plate 13. The support plate 13 can be folded relative to the straight support part 12. Since the thickness at the connection between the support plate 13 and the straight support part 12 is the smallest, it is easy to fold the support plate 13.

[0056] In actual use, in the support strip 1 with support plate 13 of this embodiment, the support end and support plate 13 can support the faceplate at the first edge 31 and the second edge 32 on the foam 3 respectively, ensuring that the faceplate edge at the two points is straight, which can effectively improve the appearance.

[0057] Whether the support strip 1 of Embodiment 1 or Embodiment 2 is configured in the leg support, the support strip 1 can support the cover at the upper edge of the foam 3, provide rigid support for the cover at its edge, block the transmission of the covering and pulling force of the cover to the foam 3, so as to prevent the foam 3 from separating from the skeleton 2, and effectively solve the problem that the foam 3 is prone to shifting.

[0058] In this solution, by configuring the support strip 1, the problem of the foam part 3 moving around on the leg rest can be effectively solved, and the problem of uneven matching gap between the cover and the plastic part can be improved; the problem of uneven matching gap between the leg rest and the seat cushion can be improved, and the appearance can be refined; the process bottleneck of not being able to place the support PE sheet due to the foam being too thin can be solved; and, its cost is low.
