The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, this adjustable safety gas-bag system comprises control module, location sensitive module and air bag device, air bag device comprises safety air bag, gas generator and crash sensor, and crash sensor is used to respond to impact strength, and sends induced signal to control module.Gas generator also is connected with control module, sends ignition signal control gaseous producer by control module and produces the igniting action.
Automotive seat are arranged on to be regulated on the slide rail, and can slidably reciprocate along regulating slide rail, when seat adjustment during to the appropriate location, utilizes securing device to be fixed.Regulate slide rail and be provided with the location sensitive module of being made up of several position transdusers, position transduser sets gradually and all is connected with control module along the adjusting slide rail.Connect by a connection channel between gas generator and the safety air bag, offer escape valve on the interface channel sidewall, this escape valve also is connected with above-mentioned control module.
The occupant regulates the position of seat as required; after the change in location of seat; the position transduser of regulating on the slide rail will be responded to the seat actual position; and induced signal is sent to control module; control module is revised the time parameter of control gaseous producer action in real time according to the induced signal that is collected; according to seat forward or the variation after leaning in real time in advance or delay quick-fried time of point of air bag device gas generator; the original time of having set is in advance revised at any time along with the variation of seat position, made safety air bag performance best protection effect.
For example seat is more forward than the original position of setting, at this moment, the occupant is near than original setting of the distance of car front portion, the occupant will contact with safety air bag than the pre-determined time in advance, if the gas generator of safety air bag is still opened according to original setting-up time the occupant is contacted in advance with safety air bag than the original time of setting, safety air bag is in inflated condition when contacting in advance, will damage the occupant, therefore control module is revised delay time automatically, make that the time ratio of time-delay is original predefinedly will lack, shorten the quick-fried time of point of the gas generator of safety air bag, thereby avoid injury the occupant; But; when if seat leans on the back than predefined position; this moment, the occupant was from far away than original setting of the distance of car front portion; if the gas generator of safety air bag is still quick-fried according to the time point of original setting; when the occupant contacts with safety air bag; safety air bag has leaked a part of gas; so in order to protect the occupant effectively; when seat leans on the back than predefined position; position transduser will be revised delay time; the time that adds long time delay makes the gas generator of safety air bag more quick-fried than predefined time-delay point, makes safety air bag bring into play best protection effect to the occupant.
