The specific embodiment
The utility model embodiment provides a kind of automotive seat that have safety air bag, and as shown in Figure 1, these automotive seat comprise backrest 10, headrest 20 and safety air bag 30.
It will be appreciated by those skilled in the art that: safety air bag is assembly parts, generally includes parts such as housing, airbag, gas generator.When automobile did not bump, airbag was compressive state, and parts such as airbag and gas generator all are contained in enclosure interior.When auto against, airbag is inflation under the effect of gas generator, ejects from housing, and human body is played a protective role.
Automotive seat constitution diagram when Fig. 2 opens fully for air bag, safety air bag 30 is arranged on the top of backrest 10, when this automobile is bumped, can block headrest 20 after airbag 301 is opened fully.The automotive seat that present embodiment relates to are not limited to the seat of chaufeur, also comprise passenger's seat.When being bumped, the airbag 301 inflation expansions in the safety air bag 30, the occupant is subjected to stopping of airbag 301 when moving backward, reduced the move distance of head and neck, therefore can head and the neck of human body be played a protective role.
Preferably, when automobile was bumped, airbag 301 was opened fully, and airbag 301 is provided with the groove 302 for the protection of head and neck.The motion of head back can be limited in the rear of groove 302, and the both sides of groove 302 can be played the effect of guiding and restriction to head in the motion of side direction.
The installation of safety air bag 30 on automotive seat can be in the following way: as shown in Figure 3, usually safety air bag 30 can be provided with housing, at housing fixed bolt 303 is set, double-screw bolt 303 is passed backrest 10, cooperate with double-screw bolt 303 by nut 40, thereby safety air bag 30 can be fixed on the top of backrest 10.
Further, above-mentioned safety air bag 30 is provided with wire harness 304, and an end of wire harness 304 links to each other with gas generator in the housing, and the other end passes backrest 10 crash sensors inner and on the automobile and is connected.Crash sensor is the common components on the automobile, also is provided with corresponding sensor wire harness 50 on the crash sensor, is used for transmitting collision alarm to parts such as the safety air bag that is positioned at bearing circle or gas curtains, as shown in Figure 5 and Figure 6.When bumping, crash sensor sends control signal, starts each safety air bag of automotive interior, and control signal reaches safety air bag 30 in this enforcement by wire harness 304, reaches other safety air bags of other automotive interiors by sensor wire harness 50.When the airbag in other safety air bags was opened, the airbag in the safety air bag 30 on the backrest also can be opened, the neck of protection human body.
In order to prevent that wire harness 304 from being worn and torn by the metallic framework of backrest 10 in backrest 10 inside, therefore wire harness 304 can be set carry out cabling along the inner panel of backrest 10, extremely shown in Figure 6 as Fig. 4, make wire harness 304 along the inner panel avris cabling of backrest 10, until wire harness 304 cause seat angle adjustor 60 near, be connected with the sensor wire harness 50 of crash sensor again.
The automotive seat that have safety air bag that the utility model embodiment provides arrange safety air bag by the top at backrest; after being opened fully, airbag in the safety air bag can block headrest; to stop human body motion backward, the head of human body and neck when effectively having protected auto against.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
