Portable ergonomic cushion with adjustable angle

Technical Field

The utility model relates to the technical field, in particular to a portable ergonomic cushion with an adjustable angle.

Background

Ergonomics is an application discipline which is centered on humans, studies the interrelations among humans, machinery equipment and work environments, explores work ways which adapt to the physiological and psychological requirements of humans, and aims to create healthy, safe, comfortable and efficient work environments and conditions. Musculoskeletal diseases are closely related to sitting postures, and many human engineering studies show that there is a certain relationship between postures and posture changes and human comfort. Sitting posture work is the most common and popular work mode at present, and when the person sits in front of a computer to work, the influence of the posture on the comfort level is large. The comfortable feeling is brought to people by reasonable sitting posture, and the long-term unreasonable sitting posture can affect the body health and even cause body injury. The office table and chair is the furniture which is contacted with the human body most closely in sitting posture work. The human body mostly depends on the seat to achieve the balance of one limb, and the comfort level of the seat and the cushion is very important. The comfort of the seat cushion is related to the sitting posture of a human body, the structure of the seat and the material performance of the seat cushion. The cushion can alleviate various discomforts of a human body caused by direct contact with a harder seat to a certain extent, and meanwhile, the cushion with scientific design is favorable for keeping a good sitting posture and reducing the risk of musculoskeletal injury, so that the working efficiency of the cushion is better improved.

Occupational musculoskeletal diseases are directly or indirectly caused by occupational harmful factors, are manifested by discomfort, injury, persistent pain or limited movement of tissues such as muscles, tendons, joints, bones, nerves, ligaments, cartilage, intervertebral discs, can affect various parts of the body, and among the occupational musculoskeletal diseases, lumbago is the leading cause. The risk factors of the occupational musculoskeletal diseases of the waist are mainly because the erector spinae muscles and iliocostal muscles of the waist are in a tense state for a long time when the same sitting posture is kept for a long time or the wrong sitting posture is kept for a long time, and the gluteus maximus, gluteus medius, abdominal rectus abdominus muscles, abdominal transverse muscles and abdominal internal and external oblique muscles of the hip are relatively weak, so that musculoskeletal injuries are more likely to occur. In fact, when a human body keeps various bad postures during work, the burden of musculoskeletal load of each joint of the human body is increased, muscles are kept in a state of long-term unbalance and tension, and musculoskeletal damage is easily caused. In the work, the height of the seat and the gradient of the seat are properly adjusted, the sitting posture is timely adjusted to ensure that the sitting posture is correct and comfortable, the pressure of musculoskeletal force can be effectively relieved, and the injury of the musculoskeletal force is relieved.

Currently, human ergonomics for occupational musculoskeletal disorders have just begun, and many ergonomically influencing factors are involved in the development of occupational musculoskeletal disorders.

The cushion is a common product placed on the seat, and aims to maintain scientific sitting posture, form good habit, reduce hidden troubles of diseases such as lumbar intervertebral disc protrusion, lumbar muscle strain and the like and protect the health. Most of the existing cushions pay attention to the problems of warm keeping, comfort and the like, most of the existing cushions adopt sponge, latex and other integrated structures, the shapes and the structures of the cushions are relatively fixed, and the heights of four sides and the center of the cushions are relatively uniform. The habitual forward slippage of the human body when the human body is in a sitting position cannot be avoided, so that the stress of muscles of the waist, the hip and the lower limbs is changed, the waist cannot be supported, the pressure born by the waist is increased, and the risk that the human body suffers from diseases such as lumbar intervertebral disc protrusion and lumbar muscle strain is increased due to the long-term increased pressure of the waist. Meanwhile, unreasonable pressure distribution can increase the pressure of the buttocks and the legs, and the pressure of nerves and blood vessels of the thighs is increased, so that the discomfort such as pain and the like is easily caused, and the phenomena of numbness and edema of the lower limbs are easily caused. And a part of the seat cushion has a front-back height difference to form a certain seat inclination angle, but the height and the angle are fixed accordingly. Meanwhile, the angles are also selected irregularly, and the stress on the front parts of the thighs is increased by a small elevation angle; the larger elevation angle is opposite to the larger elevation angle, so that the stress of the buttocks is increased, the sitting posture is unscientific, and the risk of diseases such as gluteal myofascitis is easily increased.

Most of the ergonomic products on the market today regarding seating are mainly focused on seats and vehicle seats, while little research has been done on seat cushions. The cushion product is guided by human ergonomics, people are promoted to protect the body by scientific sitting postures, diseases similar to lumbar intervertebral disc protrusion, lumbar muscle strain and the like are reduced, and the cushion has important significance for protecting the body health.
