INFLATOR STRUCTURE

To meet all the performance and quality requirements for airbags, we now manufacture three types of airbag inflators that employ different methods.

PYROTECHNIC METHOD

Gas generation through combustion of propellant.

COMPRESSED GAS METHOD

Release of inert compressed gas.

HYBRID METHOD

A combination of pyrotechnic and compressed gas methods.

Also, by leveraging our expertise gained in pyrotechnics, we are developing and manufacturing PGGs, initiators and other new products that work instantaneously.

INITIATOR

The ignition device is trig-gered by an electrical signal. It can be deployed in a variety of applications.

Gas Emitted Through Diffuser Window

An airbag system comprises an inflator that activates upon receiving a signal from collision sensors and a bag that inflates like a balloon. When the sensors detect a collision, a signal is sent to the ECU (a device containing circuitry for diagnosing a collision). If the ECU determines a collision has occurred, it generates an ignition current to activate the inflator within a few milliseconds, which inflates the airbag to protect the occupant.

DUAL-STAGE INFLATORS FOR DRIVER/PASSENGER AIRBAGS

CYLINDER-TYPE INFLATORS FOR PASSENGER AIRBAGS

INFLATORS FOR SIDE CURTAIN AIRBAGS

This gas-generating system protects an occupant’s head in a side collision. It employs the pyrotechnic, compressed gas, and hybrid methods.

INFLATORS FOR SIDE AIRBAGS

This gas-generating system protects an occupant’s chest and abdomen in a side collision. It employs the pyrotechnic and hybrid methods.

INFLATORS FOR KNEE AIRBAGS

This gas-generating system protects an occupant’s legs in a head-on collision. It employs the pyrotechnic and hybrid methods.

DSTT Product

GAS GENERATORS FOR SEAT BELT PRETENSIONERS (PGG)

This gas generator protects an occupant by retracting the seat belt during a collision. It employs the pyrotechnic method.

Our Products

GAS GENERATORS FOR SEAT BELT PRETENSIONERS

(PGG)

During a collision, the seat belt remains locked while the pressure is dispersed maximally to the chest area.

After the collision, the PGG applies force to the piston, causing the pretensioner to instantly pull on the seat belt, restraining the occupant in the seat.

After the collision, the inflation of the airbag reduces the force applied to the head and chest area.

At the same time, the seat belt tension is moderately eased by the activation of force limiters.

POWER DISCONNECT DEVICE

This device provides an instant disconnection of an electrical harness for facilities or equipment that require an emergency electrical disconnection. It is used primarily with hybrid and electric vehicles to prevent leakage from a battery during a collision.

PIN THRUSTER

This device instantly pushes out a pin. It is expected to be used as a hood lifter to protect people in the event of a car collision where it is necessary to push out a pin in an emergency situation.

PIN PULLER

This device instantly pulls a pin. It is used on devices that require a pin to be pulled in an emergency situation.
