2025-04-28 10:12:48

As an assembly part on the car, car seats are increasingly valued by manufacturers and users. Car seats are the permanent intersection between the driver and the occupants, and their performance is directly related to the comfort and safety of the passengers. At the same time, the appearance, shape and firmness of the seat also affect the aesthetics and reliability of the vehicle.

1. Purpose

The main purpose of car seat testing is to ensure that the seat can provide adequate support and protection under various conditions, ensure the safety of passengers, and improve ride comfort. The following requirements should also be met:

1. Safety: By simulating dynamic tests in real crash situations, the strength of the seat and its connection to the vehicle fixtures, as well as the protective performance of the seat for occupant safety, are tested.

2. Comfort: Through modal testing and pressure distribution collection, the frequency response characteristics and stress distribution of the seat are tested to ensure that the seat has good absorption and vibration damping capabilities, so that it is controlled within the comfort range of the human body.

3. Reliability: Through fatigue durability and strength tests, test the seat assembly, skeleton, slide rail and other adjustment devices should have sufficient strength and predetermined service life.

To sum up, car seat testing is of great significance to ensure driving safety and comfort.

2. Introduction to the laboratory

The seat laboratory of Zhejiang ATTC Automotive Technical Service Co., Ltd. is equipped with the most advanced testing equipment in the industry, including: simulated human entry and exit durability test robot system, bump peristaltic durability test bench, high and low temperature multi-functional test bench, SPI pressure distribution acquisition system, H-point human model, 3D (point cloud) scanner, thermal imager, etc.

epilogue

The car seat test is like a comprehensive "physical examination" of the car seat. Through various tests, you can see whether the seat is comfortable, such as whether people can find a suitable posture when they sit on it, and they will not feel tired after sitting for a long time. It can also check whether the seat is safe or not, and whether it can protect passengers well in the event of a car collision or other accident, such as whether it will break, whether the seat belt is firmly fixed, etc.

In addition, through testing, you can also know whether the seat is durable, whether it is wear and tear in daily use, or the test of some special situations, such as high temperature and humid environment, whether its performance will decline. In short, the car seat test is to make us sit more comfortably and safer, so that the seat can function stably for a long time, and provide a guarantee for our riding experience.

Therefore, we must pay attention to the experience of the seat for the passenger, which is not only comfortable, but also safe.
