Abstract
The utility model relates to a vehicle safety device. Aiming at the problem that the existing safety air bag in the ejected state can cause the injury on passengers in off-position states in a vehicle, the utility model provides a double-air-bag passenger air bag with the advantages that the structure is simple, the cost is low, and in addition, the protection function on normal passengers cannot be influenced. The double-air-bag passenger air bag has the concrete scheme of comprising an outer layer air bag, wherein an inner layer air bag is arranged in the outer layer air bag, the volume of the inner layer air bag is 30 percent to 60 percent of that of the outer layer air bag, an exhaust hole and an air inlet hole are arranged on the inner layer air bag, and the air inlet hole is connected with an air generator. The double-air-bag passenger air bag has the advantages that on the premise of not influencing the protection on the passengers in the normal sitting posture, the injury on the passengers in the off-position state during the safety air bag ejection can be greatly reduced, in addition, the structure is simple, and the cost is low.
Description
Technical field
The utility model relates to a kind of safety device of vehicle, particularly a kind of pair of airbag occupant air bag.
Background technology
Safety air bag can be given the occupant when serious collision takes place vehicle life has become the standard security equipment of vehicle with protection.Since safety air bag require the utmost point after the triggering in the short time (about 0.03 second) just airbag is full of; Therefore safety air bag flick gas filed speed can be up to 320 kilometers/hour; So probably at that time too near the safety air bag occupant of (or claiming undocked state), wait such as child or the adult that do not fasten the safety belt to damage.The main solution of taking at present is on seat or vehicle body, occupant detection sensors to be installed, and near detecting safety air bag, man-hour ability SELF CL safety air bag is arranged.Utility model patent (the notification number: CN 201080167Y of China national Department of Intellectual Property disclosed by name " a kind of airbag control device that has position control function for passenger " for example; The day for announcing: 2008-07-02), to the effect that: the linking to each other of the gas generator of inertia flip flop equipment and belt with pre-load device; The inertia flip flop equipment links to each other with the time delays device, and the time delays device links to each other with safety air bag; Position transduser is installed on the seat, and position transduser links to each other with the time delays device; The quick-fried power supply of point of the gas generator of described belt with pre-load device is controlled by the inertia flip flop equipment; The quick-fried power supply of point of described safety air bag is controlled by the time delays device; The time delays device is controlled by the inertia flip flop equipment.The subject matter of this method is that the precision of common sensor is not high, wrong report easily, and high-precision sensor can increase more cost, has closed safety air bag in addition and also can normal occupant's protection have been impacted.
The utility model content
The purpose of the utility model is to solve present safety air bag to be in the injury problem that the occupant of undocked state causes in to car at At time of eject, provide a kind of simple in structure, cost is low and can not influence the two airbag occupant air bags to normal passenger protection function.
For achieving the above object; The utility model adopts following scheme: a kind of pair of airbag occupant air bag; Comprise outer airbag, be provided with an internal layer airbag in the said outer airbag, the volume of said internal layer airbag is the 30%-60% of outer airbag; Said internal layer airbag is provided with deflation hole and induction opening, and said induction opening is connected with gas generating unit.In the safety air bag of common single-layer type, increase an internal layer airbag; Gas at first is full of the internal layer airbag and gets into outer airbag through deflation hole after safety air bag is triggered, and at last whole safety air bag is full of, and safety air bag just is full of after the expansion earlier fully; Significantly reduced impact dynamics to periphery; And do not influence protection to normal occupant, through the volume and the exhaust hole size of adjustment internal layer airbag, can also adjust the speed that safety air bag ejects as required in addition.
As preferably, the inwall of said internal layer airbag scribbles flame-retardant layer.Flame-retardant layer can prevent that the high-temperature gas that produces after safety air bag is triggered from getting into the burning hidden danger that causes behind the internal layer airbag fast, improved the safety when the utility model uses.
As preferably, said outer airbag and internal layer airbag are installed in the instrument desk before the vehicle front passenger's seat.Because what undocked state appearred in the occupant of front passenger's seat maybe be bigger, before being arranged at front passenger's seat, the utility model can bring into play protective effect to greatest extent to the occupant.
The beneficial effect of the utility model is: under the prerequisite that does not influence the normal sitting position passenger protection, can significantly reduce the safety air bag At time of eject to being in undocked state occupant's injury, and simple structure, with low cost.
Description of drawings
Fig. 1 is the scheme drawing of the utility model after launching.
Wherein:
The outer airbag of 1-, 2-internal layer airbag, 3-deflation hole, 4-induction opening, 5-instrument desk, A-normal sitting position occupant, B-undocked state occupant.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further:
As shown in Figure 1; A kind of pair of airbag occupant air bag is installed in the preceding instrument desk 5 of vehicle front passenger's seat, comprises outer airbag 1 and internal layer airbag 2; The volume of internal layer airbag 2 is 50% of outer airbags 1; Internal layer airbag 2 is provided with deflation hole 3 and induction opening 4, and induction opening 4 is connected with gas generating unit, and the inwall of internal layer airbag 2 scribbles flame-retardant layer.Collision happens and trigger the utility model after; Gas gets into through induction opening 4 earlier and is full of internal layer airbag 2, gets into outer airbag 1 through deflation hole 3 simultaneously, just is filled after outer airbag 1 launches earlier; So just reduced the speed that outer airbag 1 ejects; Significantly reduced the injury to undocked state occupant B, can not influence the protection to normal sitting position occupant A again, the flame-retardant layer of internal layer airbag 2 inwalls has reduced the possibility of high-temperature gas initiation fire in addition.
The utility model need not to install any complex sensing device; Only through simple modifications to original bag structure; Just can reduce safety air bag greatly and eject the potential safety hazard that the passenger is caused, having does not simultaneously influence its defencive function to the passenger, and through changing the size of internal layer airbag 2 and deflation hole 3; Can also control the response time of the utility model flexibly, expand the field of application of the utility model.
