Safety Systems Business

An inflator is a gas generator for airbags. When a squib that receives an electric signal at the time of a collision operates, it conveys heat to a propellant. Thermal ignition generates gas from burned propellant, which inflates the airbag. Nippon Kayaku manufactures and sells inflators for driver's and passenger's seats, side airbags, and knees. To further enhance the safety of automobiles, we are developing new products.

Micro gas generators are used in seatbelt pretensioners (mechanisms for winding seatbelts in an automobile collision). A squib, which receives an electrical signal in the event of a car collision, activates and ignites the propellant. The propellant burns and creates pressure that winds the seat belt. Fix your body in the correct position by taking up the seat belt and align it with the inflated airbag. This improves the effectiveness of the airbag and ensures occupant safety. Micro gas generators are also used as a pop-up hood mechanism to raise the bonnet to protect pedestrians.

Squib is an ignition component embedded in the Inflator and Micro Gas Generator. When the sensor senses an impact during an automobile collision, electric current flows into the squib, and the heat generated in the squib ignites the propellant inside the squib, and the squib operates. It is also used in mechanisms to adjust the inflation of airbags to match the occupant's body shape and in battery disconnect unit installed in electric vehicles.

The use of drones (unmanned aerial vehicles) is being promoted worldwide in the fields of logistics, surveying, inspection, and disaster relief. Nippon Kayaku develops the Parachute Safety Device PARASAFE ^® for drones by applying pyrotechnic technologies cultivated in automotive safety components such as air bag inflators and gas generators for seat belts. When PARASAFE ^® detects a drop in the drone, the pyrotechnic component is remotely actuated to inject the parachute at high speed and to safely lower the drone. In addition to preventing damage to the drone itself and the equipment it carries, it also protects buildings and people on the ground. PARASAFE ^® is full of possibilities for further expanding the scope of drone activities. We will continue to develop products that match various drones based on the needs of the drone industry and expand our lineup.
