Fig. 2 is the view showing the curtain airbag according to the various embodiment of the present invention.Fig. 3 is the view of the various embodiments showing Fig. 2.
Curtain airbag according to various embodiments of the present invention includes: air bag cushion 100, it couples with the side surface of vehicle interior, there is multiple independent cabin 110 and 150, and there is the aerating device 130 and 170 corresponding with cabin 110 and 150 so that cabin 110 and 150 optionally expands；Detection equipment 500, it for detecting the dress circle of vehicle and the shock of back row seats when vehicle collision；And control unit 300, it is for comparing from the shock of detection equipment 500 transmission so that air bag cushion 100 expands.
Although including covering the dress circle cabin 110 of the side surface of dress circle and the back row seats cabin 150 of the side surface of covering back row seats by describing air bag cushion 100 in the various embodiments of the present invention, it is clear that the quantity in cabin increases along with the increase of seat row always according to the change of type of vehicle.Therefore, in the various embodiments of the present invention, it is configured such that dress circle aerating device 130 couples with dress circle cabin 110 and back row seats aerating device 170 couples with back row seats cabin 150 including the air bag cushion 100 in dress circle cabin 110 and back row seats cabin 150.
The dress circle cabin 110 of air bag cushion 100 is positioned at the front side of B post 700, and there is the size even as big as covering whole dress circle, and the back row seats cabin 150 of air bag cushion 100 is positioned at the rear side of B post 700, and there is the size even as big as covering whole back row seats so that the cabin 110 and 150 of air bag cushion 100 is blocked essentially without by B post 700.Consequently, because only aerating device 130 and 170 is arranged in B post 700 and removes air bag cushion 100 from B post 700, so need not the anti-gear structure of such as ramp bracket so that manufacturing cost can be reduced by removing parts.
In addition; as shown in Figure 1; according to correlation technique; although the mid portion of air bag cushion 10 is blocked by B post 70 when air bag cushion 10 expand into B post 70; air bag cushion 10 is made to expand into the degree less than the desired degree of the design shape of air bag cushion 10; and the head of the passenger that therefore cannot adequately protect, will not disturb with B post 700 completely when air bag cushion 100 expands according to the air bag cushion 100 of the present invention, thus can more safely protect the head of passenger owing to air bag cushion 100 works more reliably.
Therefore, in order to remove the air bag cushion 100 corresponding with B post 700, air bag cushion 100 includes dress circle cabin 110 and back row seats cabin 150, make the air bag cushion 100 can independently-inflatable, and aerating device 130 and 170 moves on to B post 700 from C post so that dress circle cabin 110 and back row seats cabin 150 can independently-inflatable and separate.
Therefore, because the independently controlled cabin 110 and 150 of control unit 300, thus dress circle aerating device 130 makes dress circle cabin 110 expand, back row seats aerating device 170 makes back row seats cabin 150 expand, the expansion in dress circle cabin 110 and back row seats cabin 150 postpones can be different, and cabin 110 and 150 individually can expand according to collision situation, it may thereby be ensured that outstanding collision performance.
In addition, different from foregoing description, air bag cushion 100 does not include dress circle cabin 110 and back row seats cabin 150, but air bag cushion 100 itself can be completely separated into dress circle air bag cushion and back row seats air bag cushion, thus dress circle air bag cushion and back row seats air bag cushion can pass through aerating device expansion corresponding respectively, and this can derive from this technology when not by environment or design limit.
Control unit 300 compares the shock from detection equipment 500 transmission and controls, so that can first work with the corresponding aerating device being subject to higher shock in dress circle and back row seats, and if the shock detected in dress circle and back row seats is in similar level, then control unit 300 controls so that the aerating device of dress circle and back row seats can work simultaneously.This is because when carrying out dress circle crash tests and back row seats crash tests, owing to the deformation velocity of each several part of part bodyshell is different, so the speed of expansion of dress circle and back row seats air bag must be made different according to vehicle collision position.Therefore, the speed of expansion by making each several part of air bag cushion 100 is different according to vehicle collision position, it is possible to more safely protects passengers from injury, and air bag cushion can be made to work more reliably by eliminating the interference of B post 700.
Fig. 4 is the flow chart of the control method showing the curtain airbag according to the various embodiment of the present invention.Fig. 5 is the view of the position showing detection equipment.
The control method of the curtain airbag according to the various embodiment of the present invention includes: clash into comparison step S100, it detects the shock of dress circle and back row seats when vehicle collision by detection equipment 500, the shock detected is sent to control unit 300, and is compared the difference between shock by control unit 300；And operating procedure S300, it is according to the corresponding aerating device 130 and 170 of Value Operations from shock comparison step S100 derivation, and makes air bag cushion 100 expand by aerating device 130 and 170.
In clashing into comparison step S100, when when clashing into more higher than the shock of back row seats of dress circle, front aerating device 130 works earlier than rear inflation apparatus 170.In clashing into comparison step S100, when when clashing into more higher than the shock of dress circle of back row seats, rear inflation apparatus 170 works earlier than front aerating device 130.But, in clashing into comparison step S100, when the shock of dress circle and back row seats is in similar level, front aerating device 130 and rear inflation apparatus 170 are operating as simultaneously and make air bag cushion 100 expand.
Therefore, if detection equipment 500 detects the shock of dress circle and back row seats and the shock of detection is sent to control unit 300 when vehicle collision, then control unit 300 compares the shock of dress circle and back row seats, and operating and clash into corresponding aerating device so that corresponding air bag cushion 100 expands with relatively strong, then operation clashes into corresponding aerating device so that corresponding air bag cushion 100 expands with more weak.Because when one of dress circle and back row seats collide, the deformation velocity being reflected each several part of bodyshell by this operation in the expansion of air bag cushion 100 is different according to there is the position clashed into, so can Absorption shock in head of passenger better, and can more effectively support the head of passenger.
According to curtain airbag and control method thereof; because air bag cushion includes dress circle cabin and the back row seats cabin that can be independently controlled; and the aerating device of correspondence couples with cabin; so by each several part of the fully bodyshell that covering deformation velocity can be different according to position of collision, it is possible to more effectively support and more safely protect the head of passenger.
In addition, because removing the air bag cushion corresponding with B post, so ramp bracket etc. can be removed so that structure becomes simple, and decrease the quantity of parts, reduce manufacturing cost, and because being possible to prevent the expansion of air bag cushion to be interfered when vehicle collision, it is possible to control the expansion of air bag cushion more reliably, and the quality of vehicle and the satisfaction of passenger can be improved.
