Description

[0001] The invention relates to a seat cushion for seating furniture of all kinds, which enables self-ventilation without a blower unit, is portable and easy to clean, and is easily adaptable.

[0002] Various seat cushions are known in the prior art which use blower units to provide ventilation or back-ventilation of the seat of a piece of seating furniture. Seating furniture known from documents EP0201419A2 and CN205220455U may be useful for understanding the invention.

[0003] The aim of the invention is to create a seat cushion with a backrest that generates ventilation behind the seat surface in the simplest way possible.

[0004] The object of the invention is to create a seat cushion with a backrest for seating furniture of all kinds, wherein the seat cushion is ventilated from behind without a blower unit and thus constant ventilation of the seat surface is provided.

[0005] The object of the invention is solved by realizing claim 1 with its dependent claim.

[0006] A seat cushion with a backrest for all types of seating furniture was created, made from coil springs of a known design. Depending on the size of the seat, a seat cushion is woven from individual coil springs, which are twisted together. After each coil spring is twisted into the previous one, a hook at each end of the coil spring is used to secure it, preventing it from unwinding. Thus, the interconnected coil springs are secured against untwisting.

[0007] Subsequently, further coil springs are twisted in, each offset by 180 degrees, and connected at the end with the respective hook. The hook shape is specifically designed so that the end of the coil spring is bent into the coil spring itself. This creates a hook that anchors the individual coil springs together. The interlocking of the individual coil springs is intended to prevent injury or snagging.

[0008] It is also possible to form a small loop by bending the end of the coil spring inwards. Care must be taken to prevent snagging or injury from the ends. Depending on the load on the seat cushion, it is advisable to connect the individual hooks together or to run a separate rope through the resulting eyelets.

[0009] The inventive solution lies in the fact that by twisting coil springs together, a surface is created where the body does not touch the seat of the furniture when sitting. This lack of contact allows for constant ventilation of the seat surface through the seat cushion and the resulting cavity formed by the coil spring structure.

[0010] Advantageously, the material of the spiral spring is made of hardened and rust-free spring steel.

[0011] The invention is explained using an exemplary embodiment.

[0012] The following show: Figure 1: a spiral spring; Figure 2: a top view of a spiral spring; Figure 3: a side view of a spiral spring; Figure 4: a mesh of spiral springs; Figure 5: a retaining clip.

[0013] In principle, it can be stated that according to Figure 4A network of spiral springs 5 ​​serves as the basis of the invention. This network of spiral springs 5, offset by 180 degrees to each spiral spring 1, creates a seat cushion 6, which can be designed according to the size of the seating furniture.

[0014] In the Figure 1 A spiral spring 1 with an upper and lower end is shown. It is important to note that at the end of the spiral spring 1, a spiral spring end 2 is bent into a hook 7 within the spiral spring 1.

[0015] In the Figure 2 A top view of end 3 of the spiral spring 1 is visible.

[0016] According to Figure 3A side view of the coil spring end 2 is shown, from which it can be seen that the coil spring end 2 is bent into a hook 7 in the coil spring 1 at the upper and lower ends of the coil spring A. The coil spring end 2 is rounded. This creates a hook 7, which serves to connect the respective coil springs 1 to each other. This connection via the hooks 7 of the respective coil springs 1, which are connected by 180 degrees to each other, creates an end that does not cause injury or snagging on clothing.

[0017] Another way to anchor the individual coil springs 1, which are twisted together, is to attach a rope to each coil spring end 2, which is guided through the existing eyelet over the hook 7 and the coil spring end 2. This ensures that the coil springs 1 can rotate 180 degrees against each other, but cannot unscrew themselves.

[0018] There are countless ways to design the rope routing. You can attach the rope to the first and last available eyelets with a loop and pull it straight through the other eyelets, or you can pull the rope through all the eyelets of the spiral spring ends and connect the rope ends together. It's important that the rope is guided through all the eyelets so that they can rotate 180 degrees, but are prevented from twisting out. Ideally, the rope should be made of polyester.

[0019] From the Figure 4A retaining clip 8 is shown, which is preferably used to attach the seat cushion 6 to the corresponding seating furniture. This retaining clip 8 advantageously consists of a woven bend 9, which is inserted into the woven coil springs 5, with a bend 11 depending on the size of the seat, and a seat support 10, which is anchored below the seating furniture. The size of this retaining clip 8 can vary depending on the seating furniture.

[0020] In principle, the braiding bend 9 is introduced into the braid of spiral springs 5 ​​at each end and at specific points, and the seat bracket 10 is attached to the seating furniture via the bend 11. The dimensions resulting from the Figure 4 The details shown are only examples and may vary depending on the seating furniture and the size of the seat cushion 6.

[0021] Furthermore, an inventive solution is described, which describes a seat cushion with a backrest.

[0022] Conventional backrest cushions cover the entire back, preventing air circulation and moisture from escaping. This leads to sweating and all its unpleasant consequences.

[0023] The developed backrest cushion, designed to complement the inventive seat cushion, serves to allow air to circulate through a gap between the backrest and the seat back. This is achieved by a spacer fabric with a thickness of 8 to 12 mm.

[0024] The spacer fabric consists of a polyester mesh with a mesh size of approximately 2 to 10 mm on both the front and back. The two sides are connected by ultra-thin threads, known as pile threads, which maintain the spacing. The strength of this connection is so high that it cannot be compressed against the back, thus ensuring a constant distance. This material is processed using ultrasonic welding. A special anti-slip coating is applied to the back side, facing the seat back. This coating prevents the fabric from sliding on the backrest and therefore eliminates the need for additional straps or cords for attachment to the seat.

[0025] The backrest is attached by two straps connected by a slider, allowing for length adjustment. The backrest is then hung over the headrest. The straps are long enough to accommodate all common backrest types. The spacer fabric is edged with a polyester band, which can be colored, and joined by sewing, gluing, or welding. Two sections can also be joined together to create an innovative combined seat and backrest surface. Reference sign
