Abstract
A roof air bag module for motor vehicle has gas generator and air bag, and air bag is configured as has the shape of sealing oval curtain when being in vented condition, wherein air bag is configured as when being in vented condition and expandes and surround passenger and headrest from this to passenger's buttock downwards from the car roof. The utility model aims to provide a modified roof air bag, this roof air bag still realize carrying out better protection to the passenger to penetrating the thing.
Description
Technical field
The utility model relates to the roof air bag module for power actuated vehicle, has gas generator and safety air bag, and safety air bag is configured to the shape when being in inflated condition with occluded ellipse shape curtain.
Background technology
US Patent 5,470,103B discloses a kind of usually said roof safety air bag, this roof safety air bag from the roof drops down of passenger accommodation, to provide the ring protection from the above-head of passenger to shoulder when colliding.But the headrest at the head of passenger and seat is left out.
US Patent 8,087,690B2 also discloses a kind of roof safety air bag, and this roof safety air bag is inflated downwards from roof when colliding.But the roof safety air bag of this roof safety air bag and US Patent 5,470,103B is contrary and is not curtain, but be designed to barrel-shaped and around the upper torso region of passenger.Therefore, only passenger himself is surrounded except the headrest of seat.
Utility model content
Correspondingly, the purpose of this utility model is the roof safety air bag providing improvement, and this roof safety air bag also realizes better protecting passenger for penetrant.
This object is realized by roof safety air bag as described below, namely, a kind of roof air bag module for self-propelled vehicle, there is gas generator and safety air bag, safety air bag is configured to the shape when being in inflated condition with occluded ellipse curtain, and safety air bag is configured to launch when being in inflated condition from the buttocks of car roof down to passenger and surround passenger and headrest thus.
Recognize according to the utility model, when air bag to be designed to when being in inflated condition from roof drops down to the hip of passenger and to surround passenger and headrest, front can be saved and/or bearing circle safety air bag also has side airbag, even can save anti-after to ram pillow technology and safety belt tensioning device.
In addition; at least two safety air bags (chaufeur and passenger) are arranged on a position (top) like this; this make the accommodation in vehicle than placement altogether 6 or 8 other fender guards (2 frontal airbag, 2 seat safety airbags, 2 anti-after ram pillow, 2 deflagration type (pyrotechnisch) safety belt tensioning devices may be also had) easier, health also cannot skid off outside curtain in this case.
Safety air bag is configured to also surround back of seat in a preferred embodiment.Be constructed to when firmly surrounding passenger and back of seat be useful especially when safety air bag.
Therefore, in the Euro-NCAP relevant criterion that the protection realized now is not the side glass as broken, the object (collision to lorry, goods part, thin iron (traffic sign, pin)) penetrated and rollover or rolls, collides.When turning on one's side and/or collide, head can at both direction and/or front and back whipping.The injury protection of almost 100% only can be ensured at head with when being stably fixed above the waist in seat and fixing headrest and thering is no the glass fragment of side window and/or penetrate bag structure that object flies to part opens.
Under the cooperation of Collision Detection (distance radar, active breaking systems etc.) of at least also almost deferring to standard for relatively large vehicle, even safety strap can be omitted completely when the ejection speed according to safety air bag of the present utility model, because when the vehicle with high security calculates collision, it can pass through in time to expand before wounding safety air bag body tape to best straight/stand up position.
Safety air bag can be placed in the edge of two-piece type (driver/passenger) roof module-then expand/inflation, due to arrange oval have thickness around module can elasticity opening and closing rubber flange and may not inside roof lining be damaged.Then these can be substituted more valuably.
In very serious accident or vehicle falling into water (except roof lying after upset), passenger climbs out of fast by roof opening and/or is rescued if necessary, because gate open Chang Buneng is opened and rescue group separates A or B post through the clamping of conventional costliness and separating tool again when to have an accident more than 64km/h.
Along with increasing in a large number of current driver assistance function, no longer need until the instant protection (Sichtschutz) of last moment before accident.Before self-propelled vehicle can participate in accident without the need to chaufeur, automatic heavy braking is even avoided.
Valuably, safety air bag has crack line or predetermined interface, the separation unit of its safety air bag relaxed for collision rift or opening.Safety air bag lax in several seconds wherein after accident automatically can be separated and make chaufeur and passenger flee from out rapidly the automobile had an accident.This can such as by the functional realiey in contrast to safety belt tensioning device of safety strap injection device.It can also with friction heat and or additionally only outwards effect and taken apart airbag cover by the cutting metal wire heated, especially in the region of crack line or predetermined interface.
Can more easily and be stopped more at low cost according to the chaufeur of safety air bag of the present utility model because the needs less and less (drive-by wire referring to the selection as future) to bearing circle have.Usually significantly copilot's safety air bag of abduction stops forward/downward head movement easily changing.
Accompanying drawing explanation
Other marks of the present utility model and details appear in the description of accompanying drawing below.It illustrates:
Fig. 1 is according to the diagrammatic side view with the operating seat of aeration vehicle roof safety air bag of the present utility model;
Fig. 2 is the schematic front view of the operating seat coming from Fig. 1; And
Fig. 3 is the schematic sectional view of the operating seat coming from Fig. 1.
Detailed description of the invention
Show substantially with the inner space of 1 car represented, there is the passenger P be positioned on the operating seat 2 comprising back of seat 3 and headrest 9 in the accompanying drawings.
Inner space 1 is provided with roof 4, is furnished with roof air bag module 5 wherein, and its safety air bag 6 fills at accompanying drawing and illustrates and be in inflated condition.
In addition, safety air bag 6 has occluded ellipse curtain or barrel-shaped shape, its from vehicle roof 4 downwards until the buttocks of passenger P extends and therefore firmly around ground or surround passenger P, back of seat 3 and headrest 9 circlewise.
Further, safety air bag 6 launch on the direction of arrow 7 and therefore cannula-like around passenger P from top to approximately to its buttocks.In the case, whole seat 2 is besieged together with headrest 9, back of seat 3 and safety strap 11.
Therefore, passenger P does not rely on the safety strap 11 being and is fixed and is squeezed on seat 2 and can not encounters or break through bearing circle 10 or Windshield 8.
