Safety air bag is to be used for alleviating the vehicle sudden stop or to bring human injury's safety device of vehicle to the occupant when bumping, and generally sews up with the safety air bag proprietary material to form, and instantaneous inflation is with the protection related parts of human body when the vehicle sudden stop or when bumping.In order to control the shape behind the airbag aeration, in the manufacturing process of the band of gas, to increase the drawstring structure.
The air bag drawstring is arranged in the gasbag chamber, be fixed on the airbag wall, degrees of expansion during in order to the inflation of restriction gasbag chamber, the development rate at control airbag middle part, reduce in the airbag deployment process instant impact to the occupant, thereby avoid air bag the forward occupant of sitting posture to be damaged, also can provide protection after launching fully, just can realize different occupants are effectively protected without any need for occupant sensor to the occupant of normal sitting position in the expansion starting stage; This device need not the vehicle structure change, and compatible mutually with current air bag system, only uses current ignition circuit to realize.
Existing air bag drawstring form is more single, generally just be provided with one, two or three at zone line, as Chinese utility model patent ZL2008200154688, just relate to a kind of " can discharge the airbag apparatus of drawstring ", development rate by drawstring control air bag middle part launches the air bag both sides in advance.Existing airbag structure can only be controlled the thickness of zone line; Behind the middle increase drawstring, cause the centre of air bag thinner, thicker on every side, the pressure of inflation rear gasbag peripheral region can increase, thereby can increase the injury to occupant's chest; The version of existing drawstring is to the control weak effect of air bag global shape, can not satisfy the different needs of different automobile types and the shape of controlling air bag to reduce injury values to occupant's head, neck, chest.
Summary of the invention
The technical problems to be solved in the utility model, provide and a kind of existing drawstring set-up mode has been carried out improved automobile passenger side air bag drawstring, cooperate by four drawstrings, in collision, can control the shape of air bag well, thereby the contact form of change air bag and human body head, chest, belly and balance air bag are to the application force of human body head, chest, belly, and to reduce the injury of air bag to human body, it is simple in structure, controllability is strong, and is cheap.In addition, regulate, can regulate human body head, the stressed degree of uniformity of chest by length to each drawstring.
The utility model is for solving the problems of the technologies described above, and the technical scheme that is adopted is as follows:
A kind of automobile passenger side air bag drawstring, described air bag comprise airbag and in the drawstring of airbag internal fixation, described drawstring comprises root drawstring, head drawstring, chest drawstring and belly drawstring;
The fixed end of described root drawstring is fixed in the upper limb place of airbag inwall inflation inlet; Its controlled end position in airbag is equivalent to the central area behind the airbag aeration;
Head drawstring, chest drawstring, belly drawstring are respectively front wide and rear narrow structure, and the narrow end in rear portion separately is fixedly connected with controlled end respectively; Anterior wide end separately is individually fixed in the airbag inwall, after they are respectively airbag aeration in the position on the airbag inwall towards the human body head place, chest place, belly place.
More than be basic structure of the present utility model, the drawstring system that is provided can control the shape of air bag in collision, thereby the contact form of change air bag and human body head, chest, belly (chest is following) and balance air bag are to the application force at above-mentioned position, to reduce the injury of air bag to human body, have simple in structure, controllability is strong, cheap characteristics.
As optimization of the present utility model,
Described head drawstring is the isosceles trapezoid shape, and the width of the width of its narrow end in rear portion and root drawstring is corresponding, and the two connects through sutured; Its anterior wide end connects through sutured with the airbag inwall.
Described chest drawstring is the isosceles trapezoid shape, and the width of the width of its narrow end in rear portion and root drawstring is corresponding, and the two connects through sutured; Its anterior wide end connects through sutured with the airbag inwall.
Described belly drawstring is the isosceles trapezoid shape, and the width of the width of its narrow end in rear portion and root drawstring is corresponding, and with the controlled end of root drawstring between connect through sutured; Its anterior wide end connects through sutured with the airbag inwall.
More than the concrete shape of head drawstring, chest drawstring, belly drawstring is optimized; make it be easy to make; more make air bag after the inflation in the relative rule of shape at airbag and place, the anterior wide end of drawstring suture site, thereby guarantee that the utility model is more effective to the protection effect of head, chest, belly.
As further optimization of the present utility model,
Described chest drawstring and belly drawstring are isometric, and greater than the length of head drawstring.
Described head drawstring and belly drawstring are isometric, and greater than the length of chest drawstring.
Described head drawstring and chest drawstring are isometric, and greater than the length of belly drawstring.
More than be alternative optimization to drawstring length, can realize respectively as required the moment that bumps the outstanding head, chest, belly of reducing stressed, to protect the purpose of head, chest or belly emphatically.
Because the technical scheme more than having adopted, the utility model are compared with prior art, obtained technological advance is:
Cooperate with the belly drawstring by root drawstring, head drawstring, chest drawstring, effectively control the shape of air bag when realizing inflation, thereby the contact form of change air bag and human body head and chest and balance air bag are to the application force of human body head, chest and belly, to reduce the injury of air bag to human body, it is simple in structure, controllability is strong, and is cheap.In addition, regulate, can regulate human body head, chest, the stressed degree of uniformity of abdomen by length to each drawstring.The utility model is applicable to various vehicles such as car, cross-country car, commercial vehicle/comm..vehicle, when being used for collision happens automotive occupant is carried out protecting human body.
