Description

Technical Field

[0001] This utility model relates to the field of automotive seat cushion airbag testing technology, specifically a seat fixing component for testing seat cushion airbags. Background Technology

[0002] Car seat airbag testing is a crucial part of ensuring vehicle safety. Its purpose is to verify whether the airbags can function properly under various conditions, thereby effectively reducing the risk of injury to occupants in accidents. The testing covers multiple aspects: static performance testing focuses on the airbag's appearance, size, and material quality, checking for defects, measuring key dimensions, and testing material strength and abrasion resistance; inflation testing simulates a collision signal trigger, requiring the airbag to rapidly inflate to the specified pressure and form the correct protective shape within tens of milliseconds; deflation testing focuses on the airbag deflating reasonably in a predetermined manner after inflation to avoid secondary injuries; dynamic simulation testing uses a crash test bench with a crash dummy to simulate real-world collision scenarios, evaluating the airbag's protective effect by measuring the dummy's parameters.

[0003] However, in the existing technology, the test bench and the top plate are simply fixed with bolts and fasteners, and multiple fasteners are usually used for fixing. This results in a long installation and debugging time before testing, which affects the testing efficiency. At the same time, it does not reduce the difficulty of operation and has poor practicality. Utility Model Content
