The copilot air bag restraint system comprises a copilot air bag restraint system and an air bag restraint system controller, wherein a drawstring is arranged in the air pocket of the copilot air bag restraint system; one end of the drawstring is fixedly arranged in the air pocket of the copilot air bag restraint system; the other end of the drawstring is connected with a tape winder fixedly arranged on an air bag assembling box; and the tape winder is connected with the air bag restraint system controller.
Description
Technical field
The utility model relates to safe automobile air bag, relates in particular to a kind of safety air bag for the automobile copilot position.
Background technology
Co-driver the place ahead instrument panel is provided with the safety air bag of protecting the passenger that takes one's seat.Because a variety of causes is when the occupant of co-driver especially women and children occupant grade is in the attitude of offing normal when being improper attitude; traditional safety air bag seems very limited to the occupant's that offs normal protection; even safety air bag itself can damage the occupant sometimes, loses the vehicle occupant restraint system as the meaning of protection instrument.
Open day be that the patent documentation that December 16, publication number in 2009 are CN201362234Y discloses a kind of technical scheme: the safety air bag that a kind of co-driver undocked state is improved comprises being located at the safety air bag shell that vehicle interior has breather port; Be located at the aerator of the inboard also storage of safety air bag shell and supplying compressed gas; Be connected to the safety air bag shell and be inflated the pressure gas of device supply to the air cushion of car chamber direction expansion; When the passenger is in the improper development rate of air cushion of slowing down during state of taking one's seat, the passenger is in and keeps original development rate when normally taking one's seat state and launch rapidly; Minimizing is to passenger's injury.But the weak point of this technical scheme is: the reason of taking one's seat owing to the occupant is improper is more, such as because Occupant stature when lower or higher, it is far from being enough only rely on adjusting airbag deployment speed and the shape of deployment balloon not being adjusted accordingly, and the occupant also may come to harm.
Summary of the invention
The utility model main purpose is to provide a kind of the passenger side safety air bag, and it can control the shape of launching rear gasbag, and the front and back position of the centre of expansion that the control air bag contacts with the people makes occupant's head aim at the airbag deployment center.
The utility model is mainly solved by following technical proposals for the prior art problem, a kind of the passenger side safety air bag, comprise the passenger side safety air bag, safety air sac controller, airbag inside at the passenger side safety air bag arranges drawstring, it is inner that drawstring one end is fixed on the airbag of the passenger side safety air bag, and the other end links to each other bandage-winder connecting safety air bag controller with a bandage-winder on being fixed on air bag assembling box.Here, safety air sac controller is regulated drawstring length by driving bandage-winder, thereby the shape of the passenger side safety air bag after control launches and the front and back position at air-bag deployment center guarantee to contact in the optimum position with occupant's head.
As preferably, the utility model also comprises belt length sensor, LOAD CELLS and drawstring linear transducer, belt length sensor, LOAD CELLS and drawstring linear transducer connecting safety air bag controller.Judge Occupant stature by detecting belt length and occupant's body weight, thereby the release length of control drawstring (being detected by the drawstring linear transducer) makes when bumping occupant's head corresponding with the centre of expansion of the passenger side safety air bag.
As preferably, the belt length sensor setting is on Webbing retractor, and what LOAD CELLS was installed in seat sits the basin place, and the drawstring linear transducer is arranged on the bandage-winder.Come the release length of computationally secure band, drawstring at the winding radius on the taking-up device, the drawstring winding radius on bandage-winder by detecting safety strap, detect occupant's body weight by the LOAD CELLS that is installed in the sitting basin of seat place, comprehensively judge Occupant stature according to safety strap release length and body weight, safety air sac controller is regulated the release length of drawstring on this basis.
As preferably, drawstring is at least two, respectively arranges a drawstring at the inner upper-lower position of the airbag of the passenger side safety air bag, and an end and the airbag of drawstring are fixedly linked, the other end be fixed on the bandage-winder that air bag assembles on the box and link to each other.
As preferably, bandage-winder is the locking type bandage-winder.After drawstring regulate to finish with drawstring locking, to keep the passenger side safety air bag shape after the expansion.
As preferably, bandage-winder is by DC motor drive.DC motor drives control by safety air sac controller, and the DC motor drive bandage-winder rotates, to regulate drawstring length.
The beneficial effect that the utility model brings is, airbag internal placement drawstring at the passenger side safety air bag, detect and weigh and detect the stature of judging the occupant in the basin place that sits of seat by the belt length on the seat, safety air sac controller control drawstring bandage-winder is started working, regulate the length of drawstring, when bumping, the shape behind the passenger side air-bag deployment and centre of expansion front and back position are controlled, and make occupant's head aim at the airbag deployment center.

Among the figure: the 1st, bandage-winder, the 2nd, the passenger side safety air bag, the 3rd, drawstring, the 31st, upper drawstring, the 32nd, lower drawstring, the 4th, safety air sac controller, the 5th, belt length sensor, the 6th, drawstring linear transducer, the 7th, LOAD CELLS.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment: such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is a kind of the passenger side safety air bag, drawstring 3 comprises drawstring 31 and lower drawstring 32, one end of upper drawstring 31 and lower drawstring 32 is fixed in the airbag of the passenger side safety air bag 2, the other end is connected with the spool of bandage-winder 1 on being fixed on air bag assembling box, and safety air sac controller 4 is distinguished safety harness linear transducers 5, drawstring linear transducer 6, LOAD CELLS 7, bandage-winder 1 and crash sensor, gas generator; Belt length sensor 5 be installed on the Webbing retractor winding radius that detects safety strap and according to this computationally secure band discharge length, drawstring linear transducer 6 is installed in the release length that detects the winding radius of drawstring on the bandage-winder 1 and calculate according to this drawstring, and LOAD CELLS 7 is installed in the sitting basin of seat place.Bandage-winder 1 is the bandage-winder with catch gear.
An Occupant stature and the corresponding parameter list of drawstring length are set in safety air sac controller 4, safety air sac controller 4 is judged Occupant stature by belt length sensor 5, LOAD CELLS 7, search drawstring and discharge length parameter, the driving bandage-winder 1 upper drawstring 31 of adjustment drawstring 3(and lower drawstring 32) release length (being detected by drawstring linear transducer 6), when having collision to occur, the control gas generator launches the passenger side safety air bag 2.
So following feature of the utility model tool: at the airbag internal placement drawstring of the passenger side safety air bag, the stature that the occupant is judged in quality testing is born at the basin place that sits by the detection of the belt length on the seat and seat, safety air sac controller control drawstring bandage-winder is started working, regulate the length of drawstring, thereby shape and centre of expansion front and back position behind the control the passenger side air-bag deployment make occupant's head aim at the airbag deployment center.
