Description

Shaping and adjusting structure for seat cushion

Technical Field

The invention relates to a cushion, in particular to a cushion shaping and adjusting structure.

Background

Modern people generally lack movement, work at work, use computers, play games, watch television and other occasions, often forget to take a short time to get up and do little activity, and keep sitting, lying and leaning postures for a long time; people also know to sit, lie and lean for a long time, should take a good place for a short time, promote blood circulation, consume heat and promote health, but most people often cannot take a good place for a short time due to concentration of work, input of games or personal habits, so that phenomena such as weight increase and hip relaxation can be caused, and sitting, lying and leaning for a long time can often cause poor posture and incorrect posture to cause civilized diseases such as waist soreness and back pain.

Therefore, some cushion products or patent technologies with supporting and shaping effects can be called for being attached to specific parts of a human body, but the cushion products or patent technology structures are focused on whether the appearance shape accords with the ergonomics in design, and because the cushion products or patent technology structures only can be attached to specific parts of the human body such as buttocks, and can not be supported to deform after the specific parts of the human body are pressed, the cushion products or patent technology structures are not enough in supporting force, so that the supporting and shaping effects are not good.

For the above reasons, the present inventors have previously improved and innovated the prior art, and filed the taiwan patent I533825 "support and shape-forming structure" and taiwan patent M486334 "shape-forming support structure", which can improve the drawbacks of the prior art, but the prior art of the present invention mainly uses the shape-forming support structure corresponding to the buttocks for sitting and applies the adjustable shape-forming support function, and does not correspond to the waist for pressing, so that the waist cannot be subjected to the shape-forming support function, and therefore, only can apply the shape-forming function and effect of the buttocks when sitting and pressing the buttocks.

In addition, please refer to taiwan patent I658821, taiwan patent M612796, which discloses a sitting posture correcting seat cushion, which is made of hard plastic plates, so that the angle, size, shape, supporting force and the like of the sitting and leaning area cannot be adjusted, and the sitting angle, size, shape and supporting force of the sitting and leaning area are fixed, so that the sitting and leaning area cannot be suitable, matched and corresponding to different users.

Based on the above, the structure and function of the conventional cushion technology are not ideal, and there is an improved necessity.

The present inventors have thus made the present invention through numerous practical tests and experiments, based on practical experience of product design and development for many years, and with active diligent research and development thought.
