Description

Technical Field

[0001] This utility model relates to the field of automotive seat cushion technology, and in particular to a snap-on washable 3D seat cushion assembly. Background Technology

[0002] With the continuous increase in car ownership, consumers' demands for the comfort, practicality, and ease of maintenance of car interiors are growing. As a core component for enhancing the user experience of seats, the performance of car seat cushions has become a key focus for consumers. The core difference between 3D seat cushions and traditional flat seat cushions lies in their "three-dimensional bionic structure." By simulating the curve of the human spine and the contour of the buttocks through three-dimensional modeling, the seat cushion can form "multi-point support" when in contact with the human body.

[0003] Most existing car seat cushions use simple straps or anti-slip particles for securing the seat, resulting in a limited range of fixation structures. For separate backrest and seat cushion designs, the backrest often lacks a tight gripping structure, making it prone to leaning forward or shifting to the sides during seating. The seat cushion, relying solely on bottom anti-slip particles or a single strap for support, is also susceptible to sliding forward when passengers get in and out of the vehicle or adjust their posture. This shifting is particularly noticeable during sudden braking and cornering, affecting not only seating comfort but also potentially causing the seat's original support function to fail, posing a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a snap-on washable 3D seat cushion assembly, which solves the problems of traditional seat cushions being easy to slide and shift, and is convenient and quick to install.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A snap-on washable 3D seat cushion assembly includes a 3D backrest, a 3D soft cushion at the lower end of the 3D backrest, a back panel at the rear of the 3D backrest, right-angle clips at each of the four corners of the back panel, first straps fixedly connected to the upper and lower ends of the left and right sides of the 3D backrest, a first plug fixedly connected to the end of the first strap, the end of the first plug snapping into the inside of the opposite end of the right-angle clip, connecting straps fixedly connected to the left and right sides of the front end of the 3D soft cushion, a third plug fixedly connected to the end of the connecting strap, the upper end of the third plug snapping into the inside of the lower end of the right-angle clip at the lower end of the back panel.

[0006] Furthermore, a headrest is fixedly connected to the upper end of the 3D backrest.

[0007] Furthermore, a second strap is fixedly connected to both the upper left and right sides of the 3D backrest, and a second plug is fixedly connected to the lower end of the second strap.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-5 This utility model provides an embodiment of a snap-on washable 3D seat cushion assembly, including a 3D backrest 1, a 3D soft cushion 3 at the lower end of the 3D backrest 1, a back panel 4 at the rear of the 3D backrest 1, right-angle clips 5 installed at the four corners of the back panel 4, first straps 6 fixedly connected to the upper and lower ends of the left and right sides of the 3D backrest 1, and first plugs 7 fixedly connected to the ends of the first straps 6. The ends of the first plugs 7 are snapped into the inside of the opposite ends of the right-angle clips 5. Connecting straps 10 are fixedly connected to the left and right sides of the front end of the 3D soft cushion 3, and the ends of the connecting straps 10 are fixedly connected to... There is a third plug 11, the upper end of which is snapped into the lower end of the right-angle clip 5 at the lower end of the back panel 4. The upper end of the 3D backrest 1 is fixedly connected to the headrest 2. The upper left and right sides of the 3D backrest 1 are fixedly connected to the second straps 8. The lower end of the second straps 8 is fixedly connected to the second plug 9. The lower end of the second plug 9 is snapped into the upper end of the right-angle clip 5 at the upper end of the back panel 4. The right side of the 3D cushion 3 is fixedly connected to the hanging ring 12. The left side of the 3D cushion 3 is fixedly connected to the third strap 13. The right end of the third strap 13 passes through the hanging ring 12 and is fixedly connected to the Velcro 14.

[0021] First, lay the 3D cushion 3 flat on the seat cushion. Then, thread the connecting strap 10 of the 3D cushion 3 through the gap between the seat and the 3D backrest. Place the main 3D backrest 1 tightly against the original 3D backrest of the seat. Next, place the back panel 4 behind the 3D backrest of the seat. By inserting the first plug 7 on the first strap 6 on both sides of the 3D backrest 1 and the second plug 9 on the second strap 8 at the top into the right-angle clips 5 at the four corners of the back panel 4, the 3D backrest 1 and the back panel 4 can be tightly clamped and fixed. This counteracts the force that causes the main 3D backrest 1 to tilt forward or shift to the sides when sitting, thus firmly fixing the main 3D backrest 1 to the seat and forming the back support frame of the seat cushion assembly. This securely installs the entire seat cushion assembly onto the seat. To further improve stability, insert the third plug 11 at the end of the connecting strap 10 upwards into the right-angle clip 5 at the bottom of the back panel 4. This operation links the 3D cushion 3 with the backrest 4, effectively preventing the 3D cushion from sliding forward while seated. Finally, the third strap 13 on the left side of the 3D cushion 3 is wrapped around the front of the seat cushion, passed through the hanging ring 12 on the right side, tightened, and secured with Velcro 14 to form a bottom wraparound restraint, ensuring the 3D cushion remains stable in all directions. The lengths of the first strap 6, second strap 8, third strap 13, and connecting strap 10 can be adjusted as needed to maintain stability. Both the 3D cushion 3 and the 3D backrest 1 are designed using 3D modeling to simulate the curve of the human spine and the contour of the buttocks, creating "multi-point support" when the cushion contacts the human body, thus improving the user experience. The hollow internal structure significantly enhances airflow, allowing air molecules to quickly penetrate and effectively optimizing breathability for a more refreshing user experience.

[0022] Reference Figures 1-5 A tabletop 15 is rotatably connected to the front side of the back panel 4. A knob 16 for fixing the tabletop 15 is rotatably connected to the upper front side of the back panel 4. Slide grooves 17 are provided on the front sides of both the left and right ends of the tabletop 15. A slider 18 is slidably connected to the inner side of the slide grooves 17. Support rods 19 are rotatably connected to the left and right sides of the lower front side of the back panel 4. The upper end of the support rod 19 is rotatably connected to the front side of the slider 18. A connecting rod 20 is fixedly connected to the opposite side of the upper end of the support rod 19.

[0023] Loosen the knob 16 at the top of the back panel to unlock the table 15, allowing it to flip down and unfold. During this process, the table 15 moves the sliders 18 in the slide grooves 17 on both sides, which in turn pushes the support rod 19 to unfold. When the table 15 rotates to be perpendicular to the back panel 4, the sliders 18 slide to the end of the slide grooves 17. At this time, the support rod 19, the back panel 4, and the table 15 automatically form a stable triangular support structure, creating a sturdy temporary table for use. To retract the table, simply flip it up and tighten the knob 16. This provides a flat surface for rear passengers to temporarily place items, eat, or entertain, effectively expanding the seat's functionality and improving space utilization.

[0024] Working principle: During installation, place the 3D cushion 3 on the seat cushion, and pass the end of the connecting strap 10 through the gap between the seat and the 3D backrest. Then, press the 3D backrest 1 tightly against the 3D backrest, and place the back panel 4 behind the 3D backrest. Insert the first plug 7 and the second plug 9 into the right-angle clips 5 respectively for fixation. Then, insert the third plug 11 into the lower right-angle clip 5 to connect the 3D cushion 3, prevent the 3D cushion 3 from sliding forward, and tighten the back panel 4. The third strap 13 is wrapped around the front of the seat cushion, then passed through the hanging ring 12 and tightened, and then fixed with Velcro 14. Passengers in the rear row can turn the knob 16 to release the fixation of the table 15, so that the table 15 can rotate downward, thereby driving the slider 18 to slide inside the slide groove 17. When the table 15 is perpendicular to the back panel 4, the slider 18 just slides to the end of the slide groove 17, thereby forming a triangular support between the support rod 19, the back panel 4 and the table 15, thus forming a simple small table.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
