Description

Seat cushion shaping adjustment structure

The present invention relates to a seat cushion, in particular, it has a shaping support area that can be extended to the waist of a human body, and the support angles of the hip plate and waist plate can be changed, thereby adjusting the size, shape, and support of the shaping support area. Strength, etc., in order to suit, cooperate and respond to different users, and the waist plate and hip plate have mutual traction and linkage functions, thereby enhancing the cushion shaping and supporting effect of the cushion shaping adjustment structure.

Press; Modern people generally lack exercise, such as working, using computers, playing video games, watching TV and other occasions. They often forget to get up regularly to do some activities and maintain long-term sitting, lying and leaning postures. People also know that long-term When sitting, lying, or leaning, it is advisable to get up and move around regularly to promote blood circulation, consume calories, and improve health. However, due to concentration on work, involvement in games, or personal habits, most people are often unable to get up and move around regularly, which will lead to weight gain. , loose buttocks and other phenomena, and sitting, lying, and leaning for a long time often lead to poor posture and incorrect posture, causing back pain and other civilized diseases.

Therefore, there are some cushion products or patented technologies that can be used for specific parts of the human body and are claimed to have support, shaping and other effects. However, the design of these cushion products or patented technology structures focuses on whether the appearance and shape conform to In terms of ergonomics, because they are only suitable for specific parts of the human body, such as the buttocks, they cannot support the specific parts of the human body and deform due to heavy pressure. Therefore, in fact, these cushion products or patented technology structures do not have enough support. As a result, the effect of supporting and shaping is not good.

Therefore, based on the above reasons, the inventor has previously made improvements and innovations to the above-mentioned prior technologies, and applied for patent cases such as Taiwan Patent No. I533825 "Support Shaping Structure" and Taiwan Patent No. M486334 "Shaping Support Structure". Although it can Improve the shortcomings of the above-mentioned prior art, but the above-mentioned inventor's old patented technology, its shaping support structure is mainly corresponding to the buttocks for them to sit on, and exerts an adjustable shaping support effect, and does not correspond to the waist For it to press against, the waist cannot receive shaping support. Therefore, when the human body sits on the buttocks, it can only exert the shaping effect and effect on the buttocks.

Please also refer to Taiwan Patent No. I658821 "Posture Maintaining Apparatus" and Taiwan Patent No. M612796 "Sitting Orthopedic Seat Cushion". Both materials are made of hard plastic plates, so the angle, size, and size of the sitting area cannot be adjusted. The shape, supporting force, etc., the angle, size, shape, and supporting force of the sitting area are all fixed and cannot be suitable, matched, or adapted to different users.

Based on the above, the structure and function of conventional seat cushion technology are still not ideal, and there is a need for improvement.

It is said that the inventor has come up with the present invention based on many years of practical experience in product design and development, as well as active research and development thinking, and numerous practical tests and experiments.

The purpose of the present invention is to provide a shaping support area that can be extended to the waist of the human body, and the support angles of the hip plate and waist plate can be changed, and the size, shape, support force, etc. of the shaping support area can be adjusted to suit the needs. , a cushion shaping adjustment structure that adapts to different users, and the waist panel and hip panel have a pulling and linking effect with each other, thereby enhancing the cushion shaping and supporting effect.

In order to achieve the above object, the present invention includes a seat cushion, which is selected from flexible materials. The seat cushion includes a hip panel and a waist panel, wherein the waist panel is extended from the hip panel and bent to connect with the hip panel. The plate forms a shaping support area; the seat cushion is provided with at least two cutouts to define at least two adjustment parts, one end of each adjustment part is connected to the hip plate, and the other end of each adjustment part is arranged on the rear side of the waist plate , the other end of each adjustment part is connected by at least one adjustment unit to form an adjustable shape that can move relatively inward or outward.

The shaping support area can be expanded to accommodate the human body's buttocks and waist pressure. By adjusting the adjustment portion, the support angles of the hip board and waist board can be changed, thereby adjusting the size, shape, and support force of the shaping support zone. etc., in order to be suitable, cooperative, and responsive to different users, and the adjusting portion enables the waist board and the hip board to have a mutual traction and linkage effect. For example, when the human body's buttocks sit and press on the hip board, a tension effect can be generated to jointly make the waist board It can tilt forward to support the waist to enhance the support for the waist. When the human waist is pressed against the waist board, both sides of the hip board can be pulled up to enhance the support for the buttocks, thereby enhancing the shaping support effect of the seat cushion. .
