Method and apparatus for correcting control system of safety air bag with seat

Abstract

The invention discloses a method and a device which can amend a security air bag control system via a seat, aims to provide a device and a method that the seat can be amended in time when the position of the seat is changed, an alarm can be given and explosion can be stopped when the seat exceeds the setting security range, and the security air bag can stop explosion when passengers can not wear seat belts and the security air bag can exert the best protection effect. The device comprises a pretension type seat belt, a security air bag and a seat, wherein, a time delayer is arranged between the security air bag control module and an air generator of the security air bag, a position sensor is arranged on the seat, and the position sensor is connected with the time delayer; the security air bag control system can be adjusted when the position of the seat can be changed, and the error of touching time of the security air bag control module aroused by the change of the position of the passenger can be amended. The device is used for vehicles to protect the security of the passenger.

Description

technical field [0001] The invention relates to an automobile safety technology, in particular to a control system of a safety air bag. Background technique [0002] The airbag is a safety device used to protect the occupants of the car, which can effectively protect the occupants and reduce injuries when the vehicle collides. But the control module of existing safety airbag has set the triggering time of the gas generator of safety airbag before leaving the factory, and the setting of this value is determined according to the normal position of seat, and in actual use process Different occupants will adjust the seat position according to their height, arm length, driving habits and comfort. The change of the seat position will make the optimal triggering time of the airbag that has been set at the factory become different. Accurate, it will not achieve the best protection effect, and may even cause damage to the occupants; in addition, the airbag is only an auxiliary prote...

Problems solved by technology

But the control module of existing safety airbag has set the triggering time of the gas generator of safety airbag before leaving the factory, and the setting of this value is determined according to the normal position of seat, and in actual use process Different occupants will adjust the seat position according to their height, arm length, driving habits and comfort. The change of the seat position will make the optimal triggering time of the airbag that has been set at the factory become different. Accurate, it will not achieve the best protection effect, and may even cause damage to the occupants; in addition, the airbag is only an auxiliary protection measure for the occupant. Generally, the airbag can only play a protective role when the seat belt is active. When the occupant is not wearing a seat belt, the airbag cannot be recognized, and at this time not only cannot protect the occupant, but will cause injury to the occupant

Such as: Although the technology disclosed in the application number 200510088725.1 of the publication number CN1903615 announced by the Chinese Patent Office on January 31, 2007 "Ignition Signal Acquisition Device and Inspection Method for Safety Airbag System" can effectively control the opening of the safety airbag, but After the position of the occupant changes, the time when the gas generator of the safety airbag cannot be corrected in time to open, so as to bring into play the best safety effect of the safety airbag; the publication number CN1678476 application number 03820934.9 title announced by the Chinese Patent Office on October 05, 2005 Although the technology disclosed in the utility model application "airbag system with vehicle occupant sensor on the airbag" also involves real-time adjustment of the ignition time of the gas generator of the airbag, this technology can only reduce but not Avoid airbag injuries, and this technology does not consider the role of pre-tensioned seat belts. In fact, using this real-time adjustment method under the condition of installing pre-tensioned seat belts will not only fail to reduce injuries to the occupants , will cause more damage
