Impact strength tester for car seat headrest

Applicable standards:

GB 15083-2006 "Automobile seats, seat fixtures and headrest strength requirements and test methods" : This standard specifies the impact strength test method of automobile seat headrest in detail, including test equipment, test conditions, test steps and evaluation of test results.

GB 11550-1995 "Car seat headrest performance requirements and test methods" 

Main parameters:

Impact energy: The tester should be able to simulate the impact energy of the head to the headrest when the car crashes, usually this energy value can be adjusted within a certain range to adapt to different test needs. For example, the impact energy of some testers can reach 20J or higher.

Impact velocity: Impact velocity refers to the speed at which the impact head hits the headrest, and this parameter is crucial for assessing the impact strength of the headrest. The tester should have an adjustable impact speed to adapt to different test standards and seat types. Common impact velocities range from 0-25km/h or higher.

Impact head type: The impact head is usually a spherical or hemispherical design to simulate the shape of the human head. The diameter and quality of the impact head should meet the requirements of the relevant standards to ensure the accuracy of the test. For example, some standard impact heads have a diameter of 165mm and a mass of 6.8kg.

Measurement accuracy: The tester should have a high measurement accuracy to ensure the accuracy of the test results. This includes the measurement accuracy of impact energy, impact velocity, acceleration and other parameters.

Test device: The test device shall include a stable support for fixing the car seat and headrest; A movable impact arm for carrying the impact head for impact testing; 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 protective net, emergency stop button, etc., to ensure the safety and reliability of the test process.
