Description

Technical Field

[0001] This application relates to the field of consumer goods technology, and in particular to a seat cushion. Background Technology

[0002] Seat cushions are a common item in daily life. Existing seat cushions typically consist of an outer cover and a filling material inside the cover, which is made of flexible materials such as sponge.

[0003] A search revealed a Chinese patent with authorization announcement number CN222031958U, which discloses a seat cushion, including a seat cushion cover, a filling material in the seat cushion cover, a flexible layer on the upper surface of the seat cushion cover, and a concave hole structure on the flexible layer.

[0004] The cushion in the aforementioned patent has the following shortcomings: Although the cushion can improve breathability and heat dissipation, and avoid the cushion temperature from being too high in summer, thus affecting the user experience, the cushion cannot be adjusted to tilt according to different sitting postures. Therefore, the comfort and flexibility of the cushion during use can be further improved. Utility Model Content

[0005] The purpose of this invention is to solve or at least alleviate the problem in the prior art that the seat cushion cannot be adjusted to tilt according to different sitting postures during use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a seat cushion, comprising a first frame, a second frame, and a seat cushion body mounted on the first frame and the second frame, wherein a connecting part for flipping adjustment is hinged between the first frame and the second frame, and the connecting part is provided with an adjustment mechanism for adjusting the tilt angle of the seat cushion body.

[0007] The adjustment mechanism includes a rotating shaft rotatably installed in the connecting part, a rotating column fixedly installed at one end of the rotating shaft, a first thread on the rotating column, and a first nut screwed onto the first thread;

[0008] The adjustment mechanism also includes a knob fixedly installed at one end of the rotating column. A plurality of positioning holes are provided on one side of the connecting part. A round hole is provided on the knob. A positioning post is provided in the round hole. A second thread is provided on the positioning post. A second nut is screwed onto the second thread.

[0009] By adopting the above technical solution, rotating the rotating column will drive the rotating shaft to rotate. The rotating shaft will then drive the second frame and the second cushion to flip through the connecting part. This allows the tilt angle of the second cushion to be adjusted according to the sitting posture requirements. By installing the first nut on the rotating column, the rotating shaft, the second frame, and the second cushion can be positioned and installed. Therefore, the tilt angle can be quickly adjusted to match the sitting posture requirements, further improving the comfort and flexibility of the seat cushion.

[0010] Optionally, all the circular holes are the same size as the plurality of positioning holes, and the plurality of positioning holes are set to the same size.

[0011] By adopting the above technical solution, positioning holes can be set to assist in the rotation of the device.

[0012] Optionally, the seat cushion body is composed of a first cushion and a second cushion.

[0013] By adopting the above technical solution, the seat cushion body is composed of a first soft cushion and a second soft cushion, which facilitates the adjustment of the tilt angle.

[0014] Optionally, the first and second cushions are connected by knitted yarn.

[0015] The above technical solution uses a knitted thread to connect the first and second soft pads, which facilitates flipping.

[0016] Optionally, the first cushion is provided with a plurality of telescopic springs, each of which is filled with a filling layer, and the filling layer does not contact the telescopic springs.

[0017] By adopting the above technical solution and setting a telescopic spring, better support and comfort can be provided for the seat cushion body.

[0018] Optionally, the filling layer is made of sponge material.

[0019] By adopting the above technical solution, the comfort of the seat cushion can be improved by using sponge material as the filling layer.

[0020] Optionally, both sides of the seat cushion body are connected by multiple connecting straps through knitted threads, and one side of each of the multiple connecting straps is wrapped with a buckle. Both sides of the first frame are provided with multiple mounting grooves corresponding to the buckles, and each of the multiple mounting grooves is fixedly installed with a mounting ring that matches the corresponding buckle.

[0021] By adopting the above technical solution, the seat cushion body can be installed on the corresponding first frame and second frame through the cooperation of multiple latches and multiple mounting rings, thereby completing the stable installation between the seat cushion body and the first frame and second frame.

[0022] Optionally, an adhesive layer for fixing is provided between the seat cushion body and the first and second frames. The adhesive layer is Velcro, and the pile surfaces on the first and second frames are wrapped with knitted yarn for installation.

[0023] By adopting the above technical solution, a Velcro adhesive layer is provided on the seat cushion body, the first frame, and the second frame, thereby achieving a stable installation between the seat cushion body and the first and second frames.

[0024] In summary, the beneficial effects of this application are as follows:

[0025] 1. In this invention, the first frame and other components work together to rotate the rotating column, which in turn drives the rotating shaft to rotate. The rotating shaft, in turn, drives the second frame and the second cushion to flip through the connecting part. This allows the tilt angle of the second cushion to be adjusted according to the sitting posture requirements. By installing the first nut on the rotating column, the rotating shaft, the second frame, and the second cushion can be positioned and installed. Therefore, the tilt angle can be quickly adjusted to match the sitting posture requirements, further improving the comfort and flexibility of the cushion body.

[0026] 2. In this application, the seat cushion body is installed on the corresponding first and second frames through the cooperation of multiple latches and multiple mounting rings, thereby achieving a stable installation between the seat cushion body and the first and second frames. By setting a telescopic spring, better support and comfort can be provided for the seat cushion body. Attached Figure Description

Thus, this application can be installed and fixed in two different ways, so it can be selected according to the situation when using it, and improve the convenience and flexibility of use.

[0055] By rotating the rotating column 9, the rotating column 9 will drive the rotating shaft 4 to rotate. The rotating shaft 4 will drive the second frame 3 and the second soft cushion 502 to flip through the connecting part 2. This allows the tilt angle of the second soft cushion 502 to be adjusted according to the sitting posture requirements. By installing the first nut 6 on the rotating column 9, the rotating shaft 4, the second frame 3 and the second soft cushion 502 can be positioned and installed. Therefore, the tilt angle can be quickly adjusted to match the sitting posture requirements, which can further improve the comfort and flexibility of the seat cushion body 5.

[0056] By rotating the knob 15, the rotating column 9 will rotate, which in turn will cause the rotating shaft 4 and the second frame 3 to flip, thereby adjusting the tilt angle. The positioning column 12 is inserted into the corresponding round hole 16 and positioning hole 11, and the second nut 14 is installed on the positioning column 12 to complete the positioning installation. This application uses two different methods for adjustment, so the choice can be made according to the situation during use, thereby improving the convenience and flexibility of use. By setting the telescopic spring 7, better support and comfort can be provided for the seat body 5.
