Description

[Technical Field]

[0001] This utility model relates to the field of lumbar support belt technology, specifically a back cross-strap structure for lumbar support. [Background Technology]

[0002] In existing technologies, common lumbar support structures typically consist of a main support component and straps located on both sides of the waist or back. These straps are tightened and then fastened to secure the support, providing wrapping and support for the waist. This type of lumbar support structure has a relatively simple design, using conventional methods such as Velcro, elastic bands, or buckles for fixation. While it can provide some lumbar support, it still has the following shortcomings:

[0003] Firstly, the single fixing position of the straps makes it difficult to personalize the fit according to different user body shapes, resulting in poor fit and comfort.

[0004] Secondly, some structures only provide tension on both sides of the waist, lacking an effective support point for the middle of the back, resulting in insufficient overall stability of the lumbar support, which is prone to slippage or support shift, especially during strenuous exercise or prolonged sitting.

[0005] Third, traditional straps often require repeated pasting during adjustment, which is cumbersome and not conducive to quick wearing and adjustment by users. [Utility Model Content]

[0006] The purpose of this invention is to address the aforementioned shortcomings by providing a cross-strap structure for lumbar support, which effectively improves stability and support during wear, enhances wearing comfort, and offers greater adaptability and functionality.
