Car seat belt locking performance tester

Applicable standards:

Automotive seat belt locking performance tester mainly meets the following national or industry standards:

GB 14166-2013 Seat belts, restraint systems, Child restraint Systems and ISOFIX Child Restraint Systems for Motor Vehicle Occupants

GB 27887-2011 Restraint System for Child Occupants of Motor Vehicles

Main parameters:

Control system:

PLC control system is usually used to realize automatic control and data processing.

Operation interface:

It is equipped with a color touch screen and supports switching between Chinese and English for easy operation.

Emergency lock test parameters:

After installation, the winder can reach a speed of 2.94m/s within 50ms to simulate the locking function in emergency situations.

Angle adjustment:

The installation Angle can be adjusted, such as the winding shaft to the horizontal plane of 45°, 90°, 135° and 180° to adapt to different test requirements.

Vehicle acceleration adjustment range:

The acceleration adjustment range is usually 0.2——1.5g （can be set） to meet the needs of different test conditions.

Acceleration adjustment step:

The acceleration adjustment step is usually less than or equal to 0.05g to ensure the accuracy of the test.

Maximum displacement of car feeling:

The maximum displacement of the car is usually 100mm, which is used to simulate the displacement of the vehicle during an emergency stop or collision.

Inductive acceleration adjustment range:

The inductive acceleration adjustment range is not less than 0.2——2.5g to adapt to the test needs of different seat belt materials.

Acceleration measurement accuracy:

The measurement accuracy of acceleration is usually less than 0.01g to ensure the accuracy of the test results.

Repeatability deviation of acceleration:

The repeatability deviation of acceleration is usually less than or equal to ±0.01g to ensure the stability and reliability of the test results.

Maximum overshoot of acceleration:

The maximum overshoot of the acceleration is usually less than 10% of the set acceleration value to ensure the accuracy of the test.

Seatbelt locking distance measurement accuracy:

Seat belt lock distance measurement accuracy is usually less than or equal to ±0.01mm, to ensure the accuracy of the test results.
