[0039] Embodiment 1

[0040] The present embodiment relates to a seat cushion lifting mechanism for a vehicle seat, which has a simple structure and is easy to operate. It can achieve upward lifting of the front portion of the seat cushion at a relatively low cost and has good market competitiveness.

[0041] In terms of overall structure, Figure 1 and Figure 2 As shown, the seat cushion lifting mechanism of the vehicle seat of this embodiment includes a mounting bracket 2 arranged between a seat cushion frame 1 and the seat cushion, and an airbag assembly 3 arranged on the mounting bracket 2 .

[0042] Furthermore, the airbag assembly 3 is arranged near the front end of the vehicle seat and connected to the external air path, and the airbag assembly 3 has an inflated state in which it bulges upward, and a deflated state in which it lies flat on the mounting bracket 2. In the inflated state, the airbag assembly 3 lifts the front part of the seat cushion upward.

[0043] It is worth mentioning that, in this embodiment Figure 1 The airbag assembly 3 shown in FIG. is in a discarded state. Figure 2 The airbag assembly 3 is shown in the inflated state. Meanwhile, the seat cushion frame 1 of this embodiment includes two side plates 11 along the width direction of the vehicle seat (i.e., the left and right direction of the vehicle), and a front connecting rod 12 and a rear connecting rod 12 connected between the two side plates 11.

[0044] At this time, combined with Figure 6 As shown, in order to realize the upward lifting of the front part of the seat cushion, the seat basin 4 for lifting the seat cushion is rotatably provided on the seat cushion frame 1. Specifically, the mounting bracket 2 and the airbag assembly 3 are arranged between the seat cushion frame 1 and the seat basin 4, so that the front part of the seat cushion can be lifted by the airbag assembly 3 in the inflated state when the seat basin 4 is lifted upward. The seat cushion of this embodiment is the part for the occupant to sit directly, and the structures not mentioned here can refer to the common seat products in the prior art, such as the foamed parts with outer covering layer.

[0045] In specific implementation, the seat cushion can be preferably set to two structural forms. In the first structural form, the front part of the seat cushion is set on the seat pot 4, and the rear part of the seat cushion rotates the rear end of the seat cushion frame 1. In this way, when the airbag assembly 3 lifts the seat pot 4 upward in the inflated state, the front part of the seat cushion can be lifted. In the second structural form, the seat cushion is set to a front half and a rear half, the front half is set on the seat pot 4, and the seat pot 4 is rotatably set on the seat cushion frame 1. When the airbag assembly 3 is in the inflated state, when the seat pot 4 is lifted upward, the front half can be lifted, thereby lifting the front part of the seat cushion.

[0046] Based on the above overall introduction, specifically, in this embodiment, as a preferred implementation form, Figure 3 and Figure 4 As shown, the mounting bracket 2 includes two support rods 21 spaced apart from each other in the front and rear directions, and a mounting plate 22 connected between the two support rods 21 , and the airbag assembly 3 is disposed on the mounting plate 22 .

[0047] Here, the supporting rod 21 and the mounting plate 22 are arranged in coordination, so that the airbag assembly 3 can be easily installed between the seat cushion frame 1 and the seat cushion, and the structure is simple, which is conducive to realizing cost-reducing design.

[0048] And, as a preferred implementation form, Figure 5 As shown, in this embodiment, the airbag assembly 3 includes a bag body 31 and connecting members 32 provided on two opposite sides of the bag body 31, and each connecting member 32 is connected to the mounting plate 22. It can be understood that the connection member 32 is provided to facilitate the connection between the airbag assembly 3 and the mounting plate 22, thereby improving the installation convenience and stability of the airbag assembly 3.

[0049] In addition, in this embodiment, as a preferred implementation form, each connecting member 32 is detachably connected to the mounting plate 22 to facilitate the later maintenance and replacement of the airbag assembly 3. And as an example, each connecting member 32 is connected to the mounting plate 22 through a screw connection structure.

[0050] In specific implementation, as a preferred implementation form, combined with Figure 4 and Figure 5 As shown, the screw connection structure includes a connection hole 321 provided on the connection member 32 , a connection through hole 221 provided on the mounting plate 22 , and a bolt assembly penetrating the connection hole 321 and the connection through hole 221 .

[0051] It can be understood that the screw connection structure includes a connecting hole 321, a connecting through hole 221 and a bolt assembly, which has a simple structure, low cost, and is conducive to convenient disassembly between each connecting member 32 and the mounting plate 22.

[0052] Secondly, in this embodiment, as a preferred implementation form, the nut in the bolt assembly is fixedly connected to the mounting plate 22, so that the bolt can be disassembled and assembled more conveniently, thereby improving the convenience of disassembly and assembly between each connecting member 32 and the mounting plate 22.

[0053] It should be mentioned that in this embodiment, in order to achieve a better layout effect, each connecting member 32 is preferably arranged on both sides of the bladder body 31 along the vehicle width direction. Of course, if necessary, connecting members 32 can also be arranged on the front and rear sides of the bladder body 31, which can also achieve the effect of fixing the airbag assembly 3.

[0054] In addition, in this embodiment, as a preferred implementation form, see Figure 3 As shown, there are multiple airbag assemblies 3 arranged at intervals along the width direction of the vehicle seat, so that the airbag assemblies 3 can cover the entire front part of the seat cushion, which is beneficial to ensure the lifting effect of the front part of the seat cushion.

[0055] At the same time, in this embodiment, as a preferred implementation form, Figure 4 As shown, the mounting plates 22 are arranged in a plurality of intervals along the length direction of the support rod 21. The advantages of such arrangement are that, firstly, compared with the design form of the entire mounting plate 22, it is conducive to reducing weight and cost, and secondly, by providing connecting holes 221 on each mounting plate 22, it is convenient to install airbag assemblies 3 of different sizes, and when the airbag assembly 3 is long and installed across multiple mounting plates 22, the gap between two adjacent mounting plates 22 can also provide a certain buffer space for the airbag assembly 3, reducing the probability of damage to the airbag assembly 3 under extreme working conditions.

[0056] In addition, in this embodiment, as a preferred implementation form, refer to Figure 2As shown, in the inflated state, the bulging height of the airbag assembly 3 is gradually lowered from front to back. This is conducive to adapting to the lifting of the seat cushion, increasing the contact area with the lifted seat cushion, and improving the lifting stability.

[0057] The seat cushion lifting mechanism of the vehicle seat of the present embodiment is configured by arranging a mounting bracket 2 between the seat cushion frame 1 and the seat cushion, and arranging an airbag assembly 3 on the mounting bracket 2. When the front part of the seat cushion needs to be lifted, it can be done by inflating the airbag assembly 3. The structure is simple and the operation is convenient, which is conducive to reducing assembly costs and subsequent maintenance costs, realizing cost-reducing design, and thus helping to enhance the market competitiveness of vehicle seats.
