Hereinafter, the operation of the airbag device 1 for a motor vehicle according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.
As in 1 . 2 and 8th illustrates when the driver's seat is the first seat 70 is fixed and the passenger seat as a second seat 72 is fixed, the seat sensor 52 capture if an occupant is in second seat 72 sits, and the detected value to the control unit 60 send. The control unit 60 may be based on the detected value of the sensor unit 50 about whether the occupant is sitting, and about the unfolding mode of the chamber part 20 decide.
The deployment mode may be in the single mode in which the occupant 74 only on the first seat 70 seated as a driver's seat, and divided into the dual mode in which the passenger 76 also on the second seat 72 sitting.
In addition, a collision mode may include a collision on a nearby side where an external impact acts on the driver's seat side, and a collision on a remote side where an external impact acts on the passenger's seat side.
The control unit 60 can control the unfolding mode for each of the collision modes and the lock release part 40 acting as a tether-releasing device, operate to adjust the operating condition of the tether portion depending on whether occupants are seated 30 determines that serves as an outer tether. Therefore, the control unit 60 the full development of the chamber part 20 Taxes.
In the single mode, in which only the occupant 74 on the first seat 70 sits, can the first tether 32 a connection with the Lock release part 40 maintained. As the length of the first tether 32 shorter than the length of the second chamber 24 may be the second chamber 24 beyond that, they are deployed while passing from the top to the bottom of the first chamber 22 is bent.
Because the first tether 32 , which serves as an outer tether, the unfolding of the second chamber 24 leads while maintaining a tension, the chamber part 20 be formed in a U-shape, which is convex upward. Because the width of the chamber part 20 corresponds to a value obtained by adding the width of the space between the first and second chambers 22 and 24 to the widths of the first and second chambers 22 and 24 is achieved, the volume of the chamber part 20 be increased in width in this case. As a movement of the occupant 74 who is on the first seat 70 sitting in the direction of the second seat 72 is limited, may cause injury to the occupant 74 therefore be reduced. That is, in the single mode, the width of the chamber part 20 be increased considerably more than the width of the first or the second chamber 22 or 24 ,
As in 4 . 5 and 8th illustrated, the latch release part 40 be actuated so that he is in the double mode in which the occupant 74 on the first seat 70 sits and the passenger 76 on the second seat 72 sits, the first tether 32 from the latch release part 40 separates.
Because a tension to pull the second chamber 24 through the first strap 32 is eliminated, the second chamber 24 towards the top of the first chamber 22 be extended. Because the bottom of the first chamber 22 at the first seat 70 or on the console box 90 is attached and the second chamber 24 towards the top of the first chamber 22 is extended, a partition wall structure between the occupant 74 and the passenger 76 be formed. Therefore, the construction can cause a collision between the heads of the occupant 74 and the passenger 76 prevent a violation caused by contact. Furthermore, the structure may normally be the upper body of the occupant 74 and the passenger 76 protect from the chest to the head.
The existing center airbags can protect occupants only in the dual mode. The airbag device 1 however, for a motor vehicle according to the embodiment of the present invention can automatically distinguish between the single mode and the dual mode and protect occupants according to each situation.
