An inflatable seat belt system comprises an inflatable bag, a pressure sensor, an ECU (Electronic Control Unit) and an air pump; the inflatable bag can be arranged on a seat belt ribbon in a sleeving mode; the pressure sensor is arranged inside the inflatable bag; the air pump is connected with the inflatable bag and used for inflating the inflatable bag; the pressure sensor is used for sensing the pressure of the inflatable bag and transmitting a pressure signal to the ECU; the ECU is used for receiving and processing the pressure signal and further controlling the air pump to perform inflation or inhalation on the inflatable bag. According to the inflatable seat belt system, the pressure inside the inflatable bag can be detected through the pressure sensor and further transmitted to the ECU, the air pump is controlled by the ECU to inflate or deflate the inflatable bag, and accordingly the structure is intelligent and simple, the use is convenient, and the requirements of a user are met.
Description
technical field [0001] The invention relates to the field of automobile safety protection, in particular to an inflatable safety belt system. Background technique [0002] With the advancement of science and technology, the passive safety technology based on airbags and seat belts is also being updated day by day. The safety protection effect of traditional seat belt technology and similar passive protection car safety devices is also more and more valued by the majority of users. However, in the traditional safety belt technology, it can only play the role of fixing the human body, and there is a certain degree of deficiency in the protection of the frontal impact of the object on the human body. [0003] The main function of the traditional seat belt is to limit the position of the driver and members when an accident occurs or emergency braking to avoid collisions between the personnel and other parts of the vehicle body, and to reduce the degree of injury to personnel in ...
