Car seat headrest static strength tester

Applicable standards:

GB 11550-2009 "Automobile seat headrest strength requirements and test methods" : This standard specifies the static strength test method of automobile seat headrest in detail, including test equipment, test conditions, test steps and evaluation of test results. This standard is the main basis of static strength test of car seat headrest in China.

ECE R17 and R21 and other Economic Commission for Europe （ECE） regulations: These regulations also contain static strength requirements for car seat headrests and apply to automotive products in the European market. While the details may differ from GB 11550-2009, the overall requirements are similar.

Us Federal Motor Vehicle Safety Regulations （FMVSS） : The US market also has its own static strength requirements for car seat headrests, which are often reflected in the relevant provisions of FMVSS. There may be some differences compared to European and Chinese standards.

Main parameters:

Load capacity: The maximum static load that the tester should be able to withstand. This parameter is usually determined according to the design and requirements of the headrest, and the common load capacity range is 500kg or higher.

Load accuracy: The measurement accuracy of the tester when a static load is applied. This parameter is crucial for assessing the static strength of the headrest, with common load accuracy of ±1% or higher.

Displacement range: The maximum amount of displacement that the tester can measure during the test. This parameter is usually determined according to the design and requirements of the headrest, and the common displacement range is between 300mm and 400mm.

Displacement accuracy: The accuracy of the tester when measuring displacement. This parameter is also important for evaluating the static strength of the headrest, with common displacement accuracy of ±1% or higher.

Test speed: Although the static strength test is mainly concerned with the measurement of load and displacement, the tester usually has a certain test speed control function to adapt to different test needs. The test speed can usually be adjusted within a certain range, such as 10-30 times/minute.

Control mode: The control mode of the tester may include manual control and automatic control. Modern tester usually adopts computer automatic control mode to improve the accuracy and efficiency of the test.

Test device: The test device shall include a stable support for fixing the car seat and headrest; A loadable static load device for applying a static load; And the necessary sensors and data acquisition systems for real-time monitoring and recording of various parameters during the test.

Safety protection: The tester should have perfect safety protection measures, such as overload protection, emergency stop button, etc., to ensure the safety and reliability of the test process.
