Introduction
Safety belts are safety parts used in equipment, flying in airplanes and other flying machines, or working at height and performing arts performances, in order to ensure the safety of the belts used. The main raw materials are polyester, polypropylene, nylon. Seat belts do not only refer to the webbing, in addition to the webbing, seat belts have other parts assembled.
"Seat belts have become a priority for drivers and passengers, and are one of the most important features of automobiles and other vehicles. Traditional components to ensure safe driving, such as mirrors and left and right door mirrors (traditional rear-view system), seat belts, AIRBAG (airbags) and ABS (anti-lock braking system) have been familiar to the majority of motorists and passengers, and in the imported luxury cars are commonly used.
Safety Belt Types
1. High-altitude Work Type
Individual protective equipment that prevents a fall of an operator from a height or suspends the operator safely after a fall. According to the different conditions of use, it can be divided into the following 3 types:
Circumference pole work safety belt
Through the rope or belt around the fixed structure to bind the human body near the fixed structure, so that the operator's hands can carry out other operations of the safety belt.
Regional restriction safety belt
Used to limit the range of activities of the operator to avoid the possibility of falling to the area of the safety belt.
Fall Suspension Harness
When a person working at a high place or climbing up to a high place falls, the safety belt will suspend the working person.
2. Semi Full Body Type
According to the operation, wear type of different, can be divided into full-body safety belt and half-body safety belt:
Full body hasty harness, that is, the safety belt wraps the whole body, equipped with lumbar, thoracic, back multiple suspension points. It can generally be disassembled into a half-body harness and a chest harness. The biggest application of full-body harness is to enable rescuers to take the "head down" way of operation without having to consider the safety belt slipping off. For example, in the deep well type of rescue, need to rescue personnel "head down" deep and close to the trapped person.
Half body hasty harness, that is, the safety belt only wrapped half-body (generally the lower half of the body, but there are such as chest safety belt, for the protection of the upper half of the body). Its scope of use is relatively narrow compared to the whole body safety belt, generally used for "seat drape".
The parameters of the harness are working tension (WS) and bursting tension (BS). These parameters vary depending on the standard and manufacturer.
3. Bungee Equipment Type
Personal fall protection systems are a set of products that are necessary to connect a worker to a fixed point and either completely prevent or stop a fall from a height. These products alone do not provide fall protection. However, when these components are combined, they form a personal fall protection system that is essential to both workplace safety and the overall fall protection program. Personal fall protection system products primarily include lanyard points, lanyard attachments, intermediate attachments, and full body harnesses.
4. Automobile Type
Traditional three-point seat belt: The traditional three-point seat belt is the most common type and consists of a shoulder belt and two lap belts that form a triangular fastening structure.
The shoulder belt runs across the occupant's shoulders, while the lap belt runs across the abdomen. This is a simple and practical structure that effectively restricts the occupant's forward, backward, and side-to-side movement during a collision.
How to make a safety belt?
Safety belt in the parts of the common processing technology in addition to weaving, stamping, injection molding, cold heading, machining, more characteristic of the pressure riveting, rotary riveting, ultrasonic welding, sewing, stamping and other assembly processes. Without doubt, sewing is also an important part of the production process, most people want to know why sewing is also important part definitely.
Actually, it has been shown that the stitch length, stitch density and stitch pattern are the three determinants of the total number of stitches and stitch density at the suture site, and they are also the three main factors affecting the degree of structural damage of the webbing. Therefore, to improve the sewing strength of seat belts, the sewing method and maximum stitch density should be selected according to the material and weaving structure of the selected webbing, as well as the material and twisting method of the sewing threads, and the sewing should be done according to the optimal sewing length on this basis.
Regular domestic sewing machines are unable to achieve these sewing results, so industrial sewing machines specialized in the production of safety belts have been created.
