Problems solved by technology

[0003] The object of the present invention is to provide a test device and method for testing the breaking strength of webbing used in automobile safety belts. The webbing is wound on the newly designed device according to a specific winding method, and the webbing is clamped by the load applied to the webbing to solve the problem of safety belts. The problem of webbing slippage in the webbing breaking strength test is that the test results are accurate and reliable

Embodiment Construction

[0035] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0036] This embodiment relates to a device and method for testing the breaking strength of webbing used for safety belts. The power part of this program is a common universal testing machine in the laboratory. Two pieces of this device form a group. The connecting end is made according to the interface of the universal testing machine. The device is mainly composed of a load-bearing frame and a locking part that acts as a locking webbing. The buckle clamping platform plays the function of transmitting load and supporting and locking the buckle. The buckle is composed of two parts with a wavy contact surface, and plays the function of locking the webbing. The webbing is wrapped around the buckle in a specific way to ensure that it does not slip during the test. The breaking strength valu...

Abstract

The invention relates to facture strength testing device and method of a ribbon for an automobile safety belt, wherein a power part is a universal testing machine usually used in a testing laboratory, the testing device takes two components as a group, a connecting end of each component is connected with the universal testing machine and manufactured according to an interface of the universal testing machine, and the facture strength testing device mainly comprises a bearing frame and a locking part which plays a role of locking the ribbon. A lock catch chucking table plays the functions of transferring a load as well as supporting and locking a lock catch, and the lock catch comprises a concave part and a concave part which have wavy contact surfaces and plays the roles of locking the ribbon. The ribbon is wound on the lock catch in a specific mode so as to ensure not to skid during the testing process. The fracture strength value is finished through the universal testing machine.

Description

technical field [0001] The invention relates to a test device and a test method for the breaking strength of a webbing used in an automobile safety belt, which belongs to the technical field of automobile product testing and can also be applied to the testing field of other textiles. Background technique [0002] The webbing is the main component of the seat belt system. It is required in Article 4.3 of the national standard GB14166-2003: it is required to test the strength of the webbing many times, but the test device and detailed operation method are not mentioned in this standard. The breaking strength of the webbing is mostly above 23kN, even up to 30kN. Since the webbing is a smooth ribbon, it is easy to slip relative to the clamping device or even slip off when a large load is applied to it. It is difficult to test its breaking strength, that is, There are the following technical problems in the prior art: there is no feasible testing device and operation method for s...
