Waist cushion with adjustable supporting curved surface

Abstract

The invention provides a waist cushion with adjustable supporting curved surface. By adjusting and maintaining the shape of the supporting curved surface, the supporting curved surface fits the waistcurved surface of each user to provide rigid support for the waist, the different regions of the supporting curved surface is separately controlled to rise or descend, different massage techniques aresimulated, and precise massage is performed on the waist.

Description

technical field [0001] The invention relates to a waist cushion with adjustable supporting curved surface shape. For different users, by adjusting the shape of the support surface of the back cushion, the back cushion and the user's waist can be closely fitted, so that the waist is more evenly stressed, so as to maintain the correct sitting posture and relieve fatigue. Background technique [0002] At present, lumbar cushions are divided into five categories: one is the soft material filling type. The cushion cover is made of textile fabrics, and the inside is filled with down, crushed sponge, cotton, PP cotton and other soft fillings. Its advantages are various shapes, low cost, and suitable for production. The disadvantage is that the filling material is soft and loosely combined with each other.

Problems solved by technology

[0002] At present, lumbar cushions are divided into five categories: one is the soft material filling type. The cushion cover is made of textile fabrics, and the inside is filled with down, crushed sponge, cotton, PP cotton and other soft fillings. Its advantages are various shapes, low cost, and suitable for production. The disadvantage is that the filling material is soft and loosely combined with each other. The support provided by this type of cushion is not enough, which makes the lumbar spine unreasonable and damages the health; the second is the elastic material shape. It is made of curved shape. Its advantage is that after the elastic material is compressed, the supporting curved surface can fully contact with the waist of the human body, which can disperse the force on the waist. The disadvantage is that the supporting force is uneven and the rigidity is insufficient. When the user's sitting posture is incorrect, the cushion cannot Strong support for the deformed lumbar spine can not restore the lumbar spine to the correct shape, and it is easy to suffer from back pain and fatigue after long-term use; the third is the rigid material integral type, and the back cushion is composed of a whole piece of hard material with a curved surface. , can provide greater support

The disadvantage is that the shape of the curved surface is fixed, there is no elasticity, and the support curved surface cannot be completely fitted to the user's waist. A curved pallet made of solid material, the pallet is connected to the bottom plate through a spring or a spring piece

Its advantage is that it has a certain support force and elasticity, and can adapt to the change of the angle of the seat back. The disadvantage is that the shape of the curved surface is fixed. For people of different heights and shapes, the support curved surface cannot be completely fitted to the user's waist, resulting in stress on the waist. Uneven, the use effect is not good; the fifth is the electric massage type, the electric massage device is installed inside the cushion, and the massage head is driven by the motor to rotate or vibrate on the human body. The advantage is that the structure is simple and can meet the massage needs of some people. The disadvantage is that , the touch is blunt, the massage method is simple, and the massage intensity and speed cannot be adjusted according to the part for precise massage
