TECHNICAL FIELD

[0001] The utility model relates to the technical field of waist rest, especially to an ergonomic posture correcting waist rest. BACKGROUND

[0002] With the continuous increase of modern people's sitting time, long-time office work, study or driving activities are prone to cause muscle tension and spine bending of the waist and back, resulting in problems such as lumbar disc herniation and muscle strain. In order to effectively prevent and alleviate the above symptoms, various auxiliary cushion products have emerged in the market, and posture correcting waist rests, as an important category, are widely used in office chairs, car seats and household seats, etc. The main function is to provide necessary support for the waist and back through reasonable support structure, to help users maintain a scientific and reasonable sitting posture, thereby reducing the health risks caused by improper sitting posture.

[0003] The posture correcting waist rest in the prior art usually adopts a whole integrated structure design, mainly including a waist rest body, a back plate and a support piece, etc. The support piece is usually made of a single hard material, which is used to fix the waist rest body on the seat and provide a unified support surface for the user's waist and back. The waist rest body generally forms a relatively fixed support shape by the built-in elastic filler combined with the hard skeleton, so as to provide overall support to the waist and back when the user sits. Its working principle relies on the elastic recovery force and structural strength of the cushion material itself, so that the waist and back can obtain basic support effect during the pressing process. However, the design of such whole structure mostly lacks the function of adjusting the partitioned support for different areas of the waist and back, so that in actual use, the support force is difficult to be dynamically adjusted regardless of the difference in user's body shape or the change in sitting posture.

[0004] However, the posture correcting waist rest in the prior art lacks effective backrest and seat cushion partition structure, which cannot provide differentiated support effect for different stress requirements of the human back and waist during long-time use, and is prone to cause local compression discomfort to the user during long-time use, especially when the back and waist are stressed, which is prone to cause fatigue and discomfort, seriously affecting the user's experience and the comfort of the product. Therefore, there is an urgent need for a posture correcting waist rest that can realize independent partition support of back cushion and waist cushion, and has the functions of buffering and adjusting the angle of swing, to effectively improve the above problems and improve the comfort and use value of the product.
