The Driver Airbag (DAB) is a facial protection device installed in the driver's steering wheel. Specifically, it is a 55-liter facial protection airbag mounted via a snap-in structure inside the steering wheel. When used in conjunction with the vehicle's seat belt, it can reduce the degree of injury to the driver's head and face. Compared with other airbags, it boasts advantages such as lower development costs and shorter development cycles. Additionally, it features a platform-based structure, which can adapt to different vehicle models with only minor modifications.
The Driver AirBag (DAB) cover is made of high-performance thermoplastic elastomer (TPO) through precision injection molding. Co-designed with the vehicle’s interior styling, it features specific pre-formed tear lines to ensure timely and smooth airbag deployment, combining aesthetics and functionality.

Automotive side airbags are designed to protect the occupant's torso during a side collision. When side impact sensors detect an impact of sufficient force, the control unit rapidly triggers the gas generator within the airbag module. The solid propellant is ignited, producing a large volume of harmless nitrogen gas that inflates and deploys the airbag in approximately 20 milliseconds. This forms a cushioning barrier between the occupant and the rigid door structure, effectively dispersing and absorbing impact energy to reduce the risk of injuries to the ribs, internal organs, and pelvis.
The Knee AirBag (KAB) relies on a gas generator to produce the high-pressure gas required for its activation. When a vehicle collides during operation, the acceleration sensor integrated in the generator detects the peak acceleration signal and duration of action upon impact—i.e., the magnitude of the collision energy. Based on this energy magnitude, the sensor automatically determines whether activation is necessary. If the collision energy meets the activation threshold, the sensor outputs an activation signal, which releases the firing pin, sequentially igniting the stab primer and booster cup assembly. The combustion of the booster cup assembly then ignites the propellant cartridge assembly, which instantly generates high-pressure gas. This gas is discharged through the baffle plate and filter screen, inflating the airbag and rupturing the trim cover. The airbag rapidly deploys in the occupant’s knee area to protect their safety.
The Passenger AirBag (PAB) is a key component of a vehicle’s passive safety system, typically installed in the instrument panel in front of the front passenger. When a vehicle experiences a collision of medium or higher intensity, sensors will quickly trigger the airbag, which completes inflation and deployment within 0.03 seconds to form a cushion. This effectively supports and protects the head and chest of front-seat passengers, avoiding or mitigating injuries caused by direct impact with hard objects inside the vehicle. The airbag then deflates rapidly to reduce secondary impact. Its primary function is to significantly lower the risk of injury or death to occupants in accidents and enhance driving safety.
Electronic Automotive Safety Restraint System – ECU & Sensors
The central controller serves as the brain of the airbag system, receiving signals from collision sensors and other input devices to determine whether to ignite and deploy the airbag. It also performs self-diagnosis to detect any system malfunctions.
The central controller is composed of components such as the ignition controller, driver circuit, storage circuit, and diagnostic circuit.
At the heart of the ignition controller lies the ignition control algorithm, which precisely determines the timing of airbag deployment and ensures robust performance even in challenging conditions like rough road surfaces—this is the core technology behind airbag control. Given the diverse structural designs of real-world vehicles and the varying characteristics of collisions they experience, numerous variations of the ignition control algorithm have been developed to seamlessly adapt to different scenarios.
Electronic Automotive Safety Restraint System – Curtain Airbag
The curtain airbag (CAB) covers the upper portion of the vehicle’s inner side panels, providing critical head protection for all occupants seated near the side in the event of a side-impact collision or rollover accident. Positioned above the door frames along the roof rails, the CAB’s coverage area can vary depending on the vehicle’s specific structure—ranging from the A-pillar to the C-pillar or even extending from the A-pillar to the D-pillar. The gas generator can either be mounted in the center of the airbag (closer to the B-pillar) or placed toward the rear end (near the C- or D-pillar). Once triggered by an ignition signal, the curtain airbag inflates within 25 milliseconds, shielding occupants from direct contact with external hard objects and significantly reducing the risk of head injuries.
Electronic Automotive Safety Restraint System – Driver-Side Airbag
Side Air Bags (SABs) are installed on the sides of car seats or inside the doors, providing critical protection to occupants' chests and heads during side-impact collisions.
There are generally two main types of side airbags: one is a head-and-chest integrated design, primarily protecting both the chest and head areas; the other is a chest-only airbag, which mainly safeguards the chest, abdomen, and pelvic regions. When used in conjunction with side curtain airbags, these systems deliver exceptional protection.
Upon receiving an ignition signal, side airbags rapidly inflate—typically within about 20 milliseconds—to cushion occupants and significantly reduce injury risks during side-impact crashes.

Safety Component - Wiring Harness
A wire harness consists of wires, connectors, and accompanying components. Depending on the customer's specific needs, the wires and connectors can be processed according to blueprints and technical specifications into customized multi-circuit assemblies—each circuit comprising one or more wires—designed to connect various functional electrical devices (or components) and enable them to operate by conducting electricity. As a critical component for linking and controlling electrical parts, the wire harness forms the backbone of an entire circuit network. Its applications are vast, serving industries and products such as transportation vehicles, construction machinery, agricultural equipment, communication devices, and energy systems—essentially any product that involves either power usage or control mechanisms relies on wire harnesses.
