[0034] Specific implementation plan:

[0035] Example 1: See Figure 1-Figure 8 The utility model is a waist block mounting structure applied to a seat-back integrated cushion. The seat-back integrated cushion 1 includes an integrally formed seat plate and a backrest plate 11. The left and right sides of the waist block 4 are respectively provided with sliding grooves 44. The waist block 4 mounting structure includes:

[0036] The strip-shaped slot 12 is provided on the backrest plate 11 and arranged in the vertical direction. The backrest plate 11 is provided with side strips 13 on the left and right sides corresponding to the strip-shaped slot 12;

[0037] The anti-skid structure is installed on the side strip 13 along its own extension direction. The side strip 13 slides in the sliding groove 44. The anti-skid structure abuts against the inner groove wall of the sliding groove 44 to prevent the top waist block 4 from sliding up and down along the extension direction of the strip groove 12.

[0038] As a preferred implementation of this embodiment, please refer to Figure 2It can be seen that in this embodiment, the anti-slip structure includes a plurality of snap-in holes 131 arranged on the edge strip 13 and spaced apart along the extension direction of the edge strip 13, and anti-slip spikes 2 snap-fitted and fixed to the snap-in holes 131, and the front end faces of the anti-slip spikes 2 abut against the front inner groove wall of the sliding groove 44.

[0039] In addition, in order to ensure that the anti-slip nails 2 can have an anti-slip effect on the top waist block 4 when the top waist block 4 is at different heights, and also take into account the aesthetics of the installation, in this embodiment, a plurality of snap-in holes 131 are evenly spaced along the extension direction of the edge strip 13 itself.

[0040] See also Figure 8 In this embodiment, the anti-skid studs 2 are all made of soft rubber material, and the rear side of the anti-skid studs 2 is provided with a clamping block 21 for cooperating with the clamping hole 131.

[0041] In this embodiment, since the anti-skid stud 2 is made of soft rubber material (such as silicone, rubber, etc.), after the anti-skid stud 2 is installed in the engaging hole 131 through the engaging block 21, it will not be easily separated from the engaging hole 131.

[0042] It should be noted that when the human body leans against the backrest board 11, the waist rests against the top waist block 4, which will give a large positive pressure to the top waist block 4. In addition, please refer to Figure 2 and Figure 8 It can be seen that the contact area between the anti-skid nail 2 and the inner groove wall of the sliding groove 44 is relatively large. At this time, the static friction between the top waist block 4 and the anti-skid nail 2 will be very large, which can ensure that the position of the top waist block 4 will not shift (even if a large vertical force is applied to the top waist block 4 at this time, the top waist block 4 will not shift in position).

[0043] When the human body leaves the seat cushion, the positive pressure applied to the waist block 4 disappears, and the static friction between the waist block 4 and the anti-slip spikes 2 decreases. At this time, the waist block 4 can be pushed to move vertically with a small force to adjust its height. Of course, the waist block 4 will not slide without external force.

[0044] Generally, 2-4 anti-skid spikes 2 will enter the sliding groove 44 to cooperate with each other to prevent the top waist block 4 from sliding along the strip-shaped groove 12, thereby achieving a good anti-skid effect.

[0045] Next, see Figure 2 and Figure 3 It can be seen that in this embodiment, the anti-skid structure further includes at least one convex rib 132 extending in the transverse direction and arranged between adjacent anti-skid studs 2 , and the convex rib 132 is fixed on the edge strip 13 .

[0046] Here, the ribs 132 can cooperate with the anti-skid spikes 2 to provide a better anti-skid effect.

[0047] Then, see Figure 4-Figure 7 It can be seen that in this embodiment, the top waist block 4 includes a front top 41, a rear top 42, and a middle block 43 connected between the front top 41 and the rear top 42, two sliding grooves 44 are respectively arranged on the left and right sides of the middle block 43, and a plurality of massage protrusions 45 spaced apart from each other are provided on the front side surface of the front top 41.

[0048] In addition, the top waist block 4 is made of soft rubber material (such as silicone, rubber, etc.).

[0049] In this embodiment, the user can choose to install the front top 41 toward the front, at this time, the massage convex head 45 can provide a better back massage experience for the back. When the massage convex head 45 is not needed, the user can choose to install the rear top 42 toward the front.

[0050] More specifically, in this embodiment, the upper end of the strip-shaped slot 12 is connected to the outside.

[0051] In this way, the top waist block 4 can be inserted into the strip slot 12 from the upper end of the strip slot 12 from top to bottom, and the installation is very convenient.

[0052] Embodiment 2 is different from Embodiment 1. Please refer to Fig. 9 It can be seen that in this embodiment, the anti-slip structure includes an anti-slip strip 3 fixed at the front end of the edge strip 13 and arranged along the extension direction of the edge strip 13 itself, and the front end surface of the anti-slip strip 3 abuts against the front inner groove wall of the sliding groove 44.

[0053] In this embodiment, the anti-slip strip 3 is made of soft rubber material (materials such as silicone and rubber can be used), and the contact area between the anti-slip strip 3 and the front inner groove wall of the sliding groove 44 is larger. When the human body leans against the backrest board 11, the waist rests on the top waist block 4, which will give a large positive pressure to the top waist block 4. At this time, there is a large static friction between the top waist block 4 and the anti-slip strip 3, which can effectively prevent the top waist block 4 from sliding up and down.

[0054] When the human body leaves the seat cushion, the positive pressure applied to the waist block 4 disappears, and the static friction between the waist block 4 and the anti-slip strip 3 decreases. At this time, a small force can be used to push the waist block 4 to move vertically to adjust its height. Of course, the waist block 4 will not slide without external force.

[0055] The above description of a top waist block mounting structure applied to a seat-back integrated cushion of the utility model is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the inventive concept of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the utility model.
