OCCUPANT PROTECTION SEAT FOR HEAD-ON CRASH
Among fatal accidents while riding on cars, about sixty percent of people are killed in frontal collisions(1*).

“Occupant protection seat for head-on crash” is a stand-alone restraint system to enhance occupant restraint performance in a frontal collision. Once sensors detect a collision, occupant restraint system launches extremely fast: it strongly retracts the lap belt and at the same time, it raises the front of the seat cushion with tugging it rearward. This work is supported by two actuators under the seat cushion that are driven by combustion of powder. The system reduces forward movement of occupant’s lumber approximately in half in our ratio(2*) and also reduces the maximum gravity that acts on the occupant.
