Description

Technical Field

[0001] This utility model relates to the field of seat cushion technology, and more specifically to a folding seat cushion. Background Technology

[0002] The folding cushion is easy to carry because it can be folded up. When playing outdoors, it can be folded up and placed in a backpack or hung on a backpack, and unfolded flat when needed for the user to sit on.

[0003] Folding cushions are widely used in outdoor picnics and camping due to their portability and ease of storage. However, existing folding cushions generally suffer from a single-function limitation. Their structures are mostly flat, providing only flat support for sitting or lying down. When users need to lean back and rest, traditional folding cushions lack an independent back support structure, relying on external objects such as trees, chairs, or rocks for support, severely restricting their use. For example, in open grasslands or beaches lacking natural support, users struggle to achieve a comfortable backrest experience, significantly impacting the convenience and comfort of outdoor rest. Utility Model Content

[0004] The purpose of this utility model is to provide a folding seat cushion that solves the problem of traditional folding seat cushions relying on external supports, so that users can comfortably lean against and rest in outdoor environments where there are no suitable supports.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A folding seat cushion includes two cushion bodies, each consisting of a bottom hard support plate and an upper soft cushion layer. The two upper soft cushion layers are sewn together by a flexible connecting strip. The two bottom hard support plates are rotatably connected by a damping pivot. A storage groove is symmetrically provided on both sides of the bottom of one of the bottom hard support plates. A telescopic support rod is provided in the storage groove. One end of the telescopic support rod is rotatably connected to the storage groove, and a pad is rotatably provided at the other end of the telescopic support rod. A pad limiting component is provided in the storage groove.

[0007] Furthermore, an installation groove is provided on one side wall of the storage slot; the pad limiting assembly includes an elastic limiting pin installed in the storage slot, a spring is connected between the elastic limiting pin and the installation groove, and a limiting hole is provided on the pad opposite the elastic limiting pin, and the elastic limiting pin is inserted into the limiting hole.

[0008] Furthermore, a toggle plate is fixedly provided on the elastic limiting pin.

[0009] Furthermore, the telescopic support rod includes a sleeve and a movable rod slidably connected inside the sleeve. One end of the sleeve is rotatably connected to the storage groove. The sleeve has multiple positioning holes spaced longitudinally at equal intervals. The movable rod has a positioning pin opposite to the positioning holes. The end of the movable rod away from the sleeve is rotatably connected to the pad.

[0010] Furthermore, the bottom of the pad is provided with an anti-slip rubber pad.

[0011] Furthermore, the bottom of the underlying rigid support plate is provided with anti-slip texture.

[0012] Furthermore, the flexible connecting strip is made of nylon fabric.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention features a telescopic support rod that can be stored in a storage slot at the bottom of the underlying rigid support plate, without affecting the folding and carrying of the cushion. When back support is needed, the telescopic support rod can be removed from the storage slot and unfolded to provide additional support for the cushion, enabling independent back support. This solves the problem of traditional folding cushions relying on external supports, allowing users to comfortably lean back and rest even in outdoor environments where there is no suitable support.

[0020] like Figures 1 to 4As shown, a folding seat cushion includes two cushion bodies, each composed of a bottom hard support plate 1 and an upper soft cushion layer 2. The two upper soft cushion layers 2 are sewn together by a flexible connecting strip 3. The two bottom hard support plates 1 are rotatably connected by a damping pivot 4. A storage groove 101 is symmetrically provided on both sides of the bottom of one of the bottom hard support plates 1. A telescopic support rod 5 is provided in the storage groove 101. One end of the telescopic support rod 5 is rotatably connected to the storage groove 101, and a pad 6 is rotatably provided at the other end of the telescopic support rod 5. A pad limiting component is provided in the storage groove 101.

[0021] An installation groove is provided on one side wall of the storage slot 101; the pad limiting assembly includes an elastic limiting pin 7 installed in the storage slot 101, and a spring is connected between the elastic limiting pin 7 and the installation groove. A limiting hole 601 is provided on the pad 6 opposite to the elastic limiting pin 7, and the elastic limiting pin 7 is inserted into the limiting hole 601; the combination of the elastic limiting pin 7 and the limiting hole 601 can limit the pad 6 when the telescopic support rod 5 and the pad 6 are stored in the storage slot 101, thereby preventing the telescopic support rod 5 from falling out of the storage slot 101.

[0022] A toggle plate 8 is fixedly installed on the elastic limiting pin 7; the user can easily control the extension and retraction of the elastic limiting pin 7 by toggling the toggle plate 8, which facilitates the unfolding and storage of the pad and improves the ease of use.

[0023] The telescopic support rod 5 includes a sleeve 51 and a movable rod 52 slidably connected within the sleeve 51. One end of the sleeve 51 is rotatably connected to the storage groove 101. The sleeve 51 has multiple positioning holes 501 spaced longitudinally at equal intervals. A positioning pin 53 is provided on the movable rod 52 opposite the positioning holes 501. The end of the movable rod 52 away from the sleeve 51 is rotatably connected to the pad 6. Through the cooperation of the positioning holes 501 and the positioning pin 53, the telescopic support rod 5 can be adjusted in length according to actual needs, adapting to different usage scenarios and user requirements. It can be flexibly adjusted to provide stable support regardless of whether the ground is flat or has a certain slope.

[0024] The bottom of the pad 6 is provided with an anti-slip rubber pad; the anti-slip rubber pad increases the friction between the pad 6 and the ground, effectively preventing the pad 6 from sliding during use, and further improving the stability and safety of the entire support structure.

[0025] The bottom of the underlying rigid support plate 1 is provided with anti-slip texture.

[0026] The flexible connecting strip 3 is made of nylon fabric.

[0027] Working principle:

[0028] During normal use, the two seat cushions can be flexibly unfolded or folded via the flexible connecting strap 3 and the damping pivot 1. When the user only needs to use them as flat seat cushions, the two seat cushions can be unfolded and laid flat. The bottom hard support plate 1 and the upper soft seat cushion layer 2 provide stable support and a comfortable sitting experience. The anti-slip texture on the bottom of the bottom hard support plate 1 prevents the seat cushion from sliding.

[0029] When the user needs to lean back and rest, the two seat cushions are rotated to form a suitable obtuse angle, which the damping shaft 1 maintains stably. The actuating plate 8 is moved to disengage the elastic limiting pin 7 from the limiting hole 601, and then the telescopic support rod 5 is taken out from the storage slot 101 and unfolded. The length of the telescopic support rod 5 is adjusted by adjusting the engagement of the positioning pin 53 with different positioning holes 501 to adapt to the ground conditions. The pad 6 is then unfolded to contact the ground. At this point, the telescopic support rod 5 and the pad 6 together form a support structure, providing reliable back support for the user.

[0030] This invention effectively solves the problem of limited functionality in existing folding seat cushions, enabling the conversion between a flat seat and one with independent back support, greatly expanding its application scenarios. Even in outdoor environments without suitable support, users can comfortably rest. Its rational structural design ensures both support strength and stability, while also balancing comfort and portability. The retractable design of the telescopic support rod 5 and the pad 6 makes the cushion compact and easy to carry when folded. Furthermore, optimized designs for various components, such as anti-slip rubber pads, anti-slip textures, and flexible nylon connecting straps, improve the cushion's lifespan and enhance its safety and convenience.
