Abstract: The purpose of this plan is to reduce the damages in intercity train crash cases to the passengers. Berth sleeper airbags are designed to protect the passenger's head and body while the passenger is asleep in the berth sleeper, which inflates in the event of a rollover accident.

Abstract: In severe traffic accidents, crumpling the front of the car causes the passenger's leg get stuck between the seat and the car's dashboard. In this article, the condition of the seat and occupant safety sack is checked, which keeps the passenger in place, in heavy crashes, then raises the occupant's knee, and pulls the front seats back as far as possible.

Abstract: The purpose of this plan is to reduce the damages in intercity train crash cases to the passengers. In the next phase, if the train catches fire with the increase in the incident time of smoke and fire entering to the train, the passenger is required to react appropriately. The coupe and the corridor are designed to prevent the fuel, fire, heat and wear from penetrating into the coupe so passengers can have plenty of time to get out of the train. In addition to sound proof its walls are heat and fire proof.

Abstract: In this device, the nozzles that often used in order to make a linear motion, so they can be helpful in rotating the disc if they are placed at the external ring of disc. In addition, in this case, apart from generating electricity from the discharging fluid of the nozzle by ionization method, the kinetic energy of the discharging fluid can be used for rotating the disc as well.

Abstract: A protective cover that is resistant to absorption and transfer of heat resistant to shocks and penetration of sharp objects and damping shocks at the events, Which combined with the seat fully covers the passenger, and protects him/her against shocks, burns and sharp objects in accidents and is searchable by location-finders.
