About This Product

[Airbag deployment device] Uses high pressure gas to simulate the gas flow rate of an actual inflator. Cold Gas System is an airbag deployment device that does not use an inflator. The compressed gas is controlled with high precision to simulate the gas flow rate of the inflator. Because it does not use an inflator, experiments can be performed as many times as you like quickly and at low cost. It also has repeatability several times that of an inflator. Application example

■System test

Airbag module development test.

■Inflator alternative

- Research and development of dashboard covers and airbag cushions. ・Research and development of airbag fabric folding. - Verification and confirmation testing of airbag modules, dashboard panels, cushions, and folding defects. ・Impactor and drop tower tests. ・Optimization experiments for new inflator development. ・Replacement of actual inflator in manufacturing process inspection.

■Main features

・Output gas flow rate can be set in the range of 0.5 mol to 8.0 mol (depending on tank capacity and injection gas pressure). ・Gas flow rate can be set by selecting the orifice bar (flow rate control opening). ・Uses an electronically controlled special valve that enables high-speed response and large flow rate. Valve drive delay: 0.2ms or less from trigger signal. (When using electronic control valve) ・Valve full opening time: 2.0ms or less from the trigger signal. (When using electronic control valve) -Can be replaced with conventional cold gas inflators, hybrid models, and pyrotechnic models. ・One-stage deployment model and two-stage deployment model can be supplied. - Compressed gases include helium, argon, nitrogen, and a mixture of these gases.

Available upon quote

Room temperature

0.5~8.0mol (Select tank capacity according to the capacity of the airbag used.)

Helium, Nitrogen (Helium can be discharged at high speed. Helium is more expensive than nitrogen.)

0.25L, 0.5L, 0.75L (The amount of gas used is determined by the total capacity of the charge tank and the gas filling pressure.)

0.25L

AC100V, 50/60Hz, 5A

Helium and nitrogen 150kg/cm2, 7m3

10kg/cm2

Up to 1-1/4 inch

It takes less than 2 milliseconds to fully open (gas discharge is fully opened within 1/500 seconds after receiving the trigger signal).

Fully closed for less than 30 seconds (The valve returns to its normal position (fully closed) after 30 seconds after receiving a trigger signal.)

5~20MPa (This is the pressure of the compressed gas that is supplied. The compressed gas pressure changes depending on the airbag deployment speed.)

Φ25mm

Maximum 20mm (Gas discharge diameter is variable and can be set from φ2mm to maximum φ20mm. Gas flow rate is determined by the orifice diameter. If you want to lower the gas flow rate, reduce the orifice diameter.)
