[0028] The utility model is further described below in combination with embodiments and drawings.

[0029] As Figure 1 Indicated, a kind of integrated in seat interior's waist support, including back A and the support main body 1 installed in back A, wherein, support main body 1 upper end rotatably connect in back A.Combination Figure 2 And 3 Indicated, back A is equipped with jacking mechanism 2, this jacking mechanism 2 can drive support main body 1 upper end rotation around back A, to make support main body 1 lower part can move forward and backward relative to back A.

[0030] Based on the above structure design, by rotating the upper end of the support body 1 on the backrest A, the lifting mechanism 2 drives the upper end of the support body 1 to rotate around the backrest A, and the lower part of the support body 1 moves forward and backward, which can change the forward and backward protrusion state of the seat waist area, and realize the forward and backward adjustment of the waist support.

[0031] In actual application, the massager B can be arranged in the support body 1, so that the car seat has the functions of waist support and massage, and realizes compact and lightweight design. Specifically, referring to Figure 5 and 6 , the massager B includes a swing arm B1 rotatably arranged on the support body 1 and a driving mechanism, the distal end of the swing arm B1 is provided with a massage head B2, and the driving mechanism is used to make the swing arm B1 reciprocate within a certain range along the width direction of the support body 1 (the width direction of the support body 1 corresponds to the width direction of the car seat), so that the massage head B2 at the distal end of the swing arm B1 forms kneading massage.

[0032] Further, as shown in Figure 2 and 3 , the lifting mechanism 2 is located at the rear side of the support body 1, and includes an air bag 21 fixedly arranged in the backrest A, as shown in Figure 6 , the air bag 21 is connected with an air pump 25. When the waist support is not used, the air bag 21 is in an un-inflated state, and the air bag 21 abuts against the rear side of the support body 1. When the waist support function is needed, the air pump 25 inflates the air bag 21, and the air bag 21 expands, so that the lower part of the support body 1 can be pushed out forward.

[0033] Further, as shown in Figure 2 and 3 , the lifting mechanism 2 further includes a mounting plate 22 arranged at the rear side of the support body 1, the upper end of the support body 1 is rotatably connected with the upper end of the mounting plate 22, the lower end of the support body 1 is in a suspended state, and the air bag 21 is fixedly arranged on the mounting plate 22. When the air bag 21 expands, the upper end of the support body 1 can be rotated upward around the upper end of the mounting plate 22, and the lower end of the support body 1 can be pushed out forward relative to the backrest A. When the air bag 21 deflates, the support body 1 can be rotated downward under the action of gravity, and the lower end of the support body 1 can move towards the mounting plate 22. Such structure design is simple and compact, does not occupy extra space, and can help to integrate a relatively large mechanical massager in the support body 1.

[0034] In order to improve the stroke of the waist support forward and backward adjustment, the number of air bags 21 is at least two, and the adjacent two air bags 21 are arranged in overlap.

[0035] In the embodiment, the number of air bags 21 is two. Specifically, please refer to Figure 3 and 7Two airbags 21 are distributed vertically along the height direction of the backrest A. The two airbags 21 are an upper airbag 211 and a lower airbag 212, with the lower airbag 212 sandwiched between the lower part of the upper airbag 211 and the mounting plate 22, meaning the two airbags 21 partially overlap. This design increases the stroke within a limited space, making the lifting mechanism 2 structure more compact. Simultaneously, the supporting force of the overlapping portion of the two airbags 21 is more even and stable, further improving the overall comfort and stability of the support.

[0036] In this embodiment, the front surface of the mounting plate 22 is provided with felt material, and the air bag 21 is fixed on the felt material. The felt material can stably fix the air bag 21 to the mounting plate 22, and at the same time, the felt material can serve as a buffer layer to reduce friction between the air bag and other components and reduce noise.

[0037] Revisit Figure 7 The upper ends of both air bags 21 are fixed to the mounting plate 22 by snap-fit ​​posts 23. This design can further restrain the air bags 21, prevent the air bags 21 from shifting or falling off due to large external forces, and improve the stability of the air bags 21 during use.

[0038] like Figure 1 As shown, a support plate 4, made of flexible plastic, is installed inside the backrest A. The support plate 4 is located at the front of the support body 1 and contacts it. In use, the support plate 4 corresponds to the user's lumbar and back position. Figure 2 and Figure 3 It can be seen that when the lifting mechanism 2 drives the lower part of the support body 1 to move forward, the support body 1 can cause the support plate 4 to deform and act as a support for the user's waist. When the support body 1 returns to the initial state, the support plate 4 can return to its original state to ensure that the surface of the backrest A is flat.

[0039] like Figure 6 As shown, the support body 1 is mounted inside the backrest A via a base plate A1. The support body 1 is slidably mounted on the front side of the base plate A1 and slides in contact with the back of the support bracket 4. The upper end of the base plate A1 is rotatably connected to the upper end of the mounting plate 22. By sliding the support body 1 up and down, the massager integrated on it can massage the user's lower back over a wide area. At the same time, by moving the support body 1 up and down, the vertical protrusion of the lumbar region of the seat can be changed, realizing the vertical adjustment of the lumbar support. This allows the lumbar support integrated into the seat provided in this embodiment to have four-way adjustment functions (front, back, up, and down), further improving the user's seating comfort.

[0040] For example Figure 4As shown, an upwardly extending suspension wire 3 is fixed to the back side of the mounting plate 22, and a rotating bracket 31 is provided on the suspension wire 3. The upper end of the base plate A1 is rotatably connected to the upper end of the mounting plate 22 through the rotating bracket 31. This design saves space and increases the flexibility and adaptability of the entire structure.

[0041] Please refer to Figure 2 and 5 To protect the components on the support body 1, a baffle 11 is fixed on the support body 1, and the front side of the baffle 11 slides in contact with the back side of the support plate 4.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
