Abstract: In today’s world ,There are new breakthroughs in the area of transportation, which is to make people feel secure. At the same time , People have been pursuing high speed ,time and time again to break the limit of traffic safety , of course ,those behaviors are also to pay great price .On the highway ,many people get injured ｏｒ disabilities ｏｒ even lose their lives because of not wearing seat belts in the traffic accidents. To make people wear seat belts, the market sold in the interior of the car is equipped with pressure sensor and safety belt alarm device .But even so the importance of wearing seat belts has not been able to cause people's full attention. The behavior of not wearing the safety belts on the highway will not be severely punished , which is not responsible for their life’s safety ｏｒ to other people's life safety. We travel is to pay attention to efficiency, both to fast travel, also safe travel, so that our life will be more beautiful. If a device is designed to integrate the existing pressure sensor and the role of a safety belt warning system, a new type of safety belt is added to ensure that the safety belt is taken from the front of the body. So ,to make people’s life much more convenient, to have safety and harmony traffic, We are based on the sensor working characteristics, the vehicle motion trigger system and the safety belt motion trigger system and so on and we have We made some researches on the safety belts, this study is a device for the safety belt in the front row of the vehicle. Through this study, we must come from the technology to force the front seats of the car to be able to further enhance the awareness of the safety belt, to further reduce traffic accidents caused casualties. Therefore, the research and design of safety belt device which is directed against people in front of the vehicle is a big project.
