Working Machine Support Belt Load Distribution

The support belt is divided into multiple functional segments: shoulder belts for upper body support, side belts for lateral support, pelvis belts for lower body support, and suspender bands connecting these segments. This segmentation allows each component to independently perform its specific function while collectively distributing the load throughout the entire upper body framework, resolving the contradiction between protecting the chest area and maintaining adequate load distribution.

The support belt system transitions from concentrating load on a single point or line to distributing load across a two-dimensional area of the waist and upper body. The combination of horizontal waist belts, vertical suspender bands, and diagonal side belts creates a distributed load-bearing network that spreads forces across multiple anatomical regions, reducing local pressure points and operator fatigue while maintaining structural integrity.

The support belt incorporates adjustable length mechanisms in key components such as the suspender bands and side belts. These adjustable elements allow the belt configuration to be dynamically modified to accommodate different operator sizes, body types, and working conditions. The adjustability features enable customization of the support system without fundamentally changing the overall structure or manufacturing process, thus maintaining ease of manufacture while significantly improving adaptability.
