The process of the constraint driver and crew 132 of pad 108 is illustrated.
As illustrated in Fig. 5 (a), taken a seat if the driver and crew 132 of co-pilot seat 104 have worn safety belt 136.Now, it is right
When vehicle impacts, never illustrate at the sensor come, to the sending action signal of airbag apparatus 100, such as Fig. 5 (b) institutes
Show, the expansion expansion of cushion pad 108.When there is angular impact, driver and crew 132 move to the diagonally forward of in-car side.In this embodiment party
In formula, central balloon 114 is protruded to the vehicle rear-side of main gasbag 112, and the head E1 of driver and crew 132 is from side head E1a with
Side surface part 162 on the outside of the car of motive capsule 114 is in contact.
Fig. 5 (c) is the figure that driver and crew 132 in Fig. 5 (b) travel further into the side of cushion pad 108.Moved to diagonally forward
It is viewed from above when the head E1 of driver and crew 132 is with being that the positive main gasbag 112 of co-pilot seat 104 is in contact, in head
Occur on portion E1 using neck E2 as axle, the power turned clockwise, i.e., the rotation 140 exemplified with arrow.Therefore, in this implementation
In mode, will be arranged on the in-car side of main gasbag 112 central balloon 114 rear view of vehicle from rear area 160 to main gasbag 112
Extension.Moreover, being provided with slit 122 between main gasbag 112 and central balloon 114.
The head E1 of mobile driver and crew 132 makes side head E1a connect with central balloon 114 in front of to in-car skew back
Touch while, head constraint 128 entrance by support, or cause be deep into head constraint 128
Portion and suffer restraints.Particularly in the present embodiment, central balloon 114 central joint 120, on side engagement portion 124 and
Engaged in the presence of lower side engagement portion 126 with main gasbag 112.Therefore, central balloon 114 is in the state of it will not damage posture
Head E1 is constrained, the rotation 140 occurred on the E1 of head more efficiently can be reduced or eliminate.According to this structure, energy
The angular speed of its rotation 140 of the head E1 of driver and crew 132 is enough reduced, the head E1 occurred along with rotation 140 can be suppressed
Injury values.
In addition, the rear area 160 of central balloon 114 behind end 166 constrain driver and crew 132 left shoulder E3a.
Right shoulder E3b of the driver and crew 132 on the outside of car is constrained to the position of the flank of in-car side by safety belt 136.But, it is left
Shoulder E3a is not constrained by safety belt 136.Therefore, when there is angular impact, driver and crew can regard left shoulder E3a as car
Front is towards vehicle front.Now, the rearward end 166 of central balloon 114 from front and top constraint left shoulder E3a, and after
It is continuous to constrain right shoulder E3b with main gasbag 112.Particularly in the present embodiment, in the presence of junction surface 120,124,126,
Central balloon 114 is engaged with main gasbag 112.Therefore, central balloon 114 can also constrain left shoulder E3a well.
As described above, in the present embodiment, the central balloon that can be supported using joint 120,124,126
114 constrain side head E1a, reduce the angular speed of head E1 rotation 140.At the same time, left shoulder E3a is energetically constrained,
The rotation occurred on the upper part of the body can also be offset.For central balloon 114, even if heavier-weight
The head E1 of driver and crew 132 is in contact on the outside of car, and central balloon 114 also will not be far off at main gasbag 112, and head
The narrowness of portion constraint 128 can be kept, therefore, it is possible to constrain head E1 with higher restraining force.Therefore, it is possible to
Efficiently suppress the injury values of driver and crew 132.
In the present embodiment, as carried out explanation with reference to Fig. 4 (b), main gasbag 112 is by instrument board 102
Expanded with clamped by vehicle window protective cover 116, posture is stable.Effect of the central balloon 114 at junction surface 120,124,126
Under, engage, separated so as to suppress central balloon 114 from main gasbag 112 so that posture is more stable with the main gasbag 112.
In the above, reference picture 5 (b) etc., illustrate the contact between driver and crew 132 and cushion pad 108 be from
Side head E13 is in contact beginning with central balloon 114.But, the way of contact between driver and crew 132 and cushion pad 108,
For example, have head E1 while being in contact with central balloon 114 and main gasbag 112, or head E1 is first since main gasbag 112
The various modes such as contact.In addition, head E1 and main gasbag 112 when also shoulder E3 and chest E4 and main gasbag 112 etc. are contacted sometimes
Etc. being in contact, reference picture 4 (b) etc..But, no matter in the case of which kind of, the structure in present embodiment can utilize head
Portion constraint, row constraint is effectively entered by the head E1 of driver and crew 132.
In Fig. 5 (b), as the rotation example occurred on the E1 of head, it is illustrated and turns clockwise 140.But, example
Such as, on the co-pilot seat of right direction jiggering, viewed from above, the inverse time centered on neck also occurs on the E1 of head sometimes
The rotation of pin.Even for the counter-clockwise rotation, the cushion pad 108 in present embodiment, then using central balloon 114 and
Head constraint 128 can also reduce or eliminate counter-clockwise rotation, moreover, can also reduce head E1 angular speed.That is, this reality
Apply airbag apparatus 100 in mode even for occur on the E1 of head turn clockwise and rotate counterclockwise among it is any
One kind rotation, can obtain effect same.
The process of driver and crew 132 is now constrained for cushion pad 108, examination is illustrated from other direction.Fig. 6 is to exemplify
Cushion pad 108 from vehicle front in Fig. 4 constrains the status of processes figure of driver and crew 132.As being illustrated Fig. 6 (a),
If the driver and crew 132 of co-pilot seat 104 have worn safety belt 136 and taken a seat.Now, when being impacted to vehicle, such as Fig. 6 (b)
Shown, main gasbag 112 deploys to the positive surface expansion of driver and crew 132, and central balloon 114 is to the in-car side of driver and crew 132
The front expansion expansion on right side in Fig. 6 (b).
As illustrated in Fig. 6 (b), the driver and crew 132 moved from seating position to the diagonally forward of in-car side make side head
E1a is in contact with the side surface part 162 of central balloon 114.Moreover, the left shoulder E3a not constrained by safety belt 136 is by center
The rearward end 166 of the rear area 160 of air bag 114 is constrained, reference picture 5 (b).Moreover, as illustrated in Fig. 6 (c), head E1 exists
While guiding by central balloon 114, constrained towards vehicle front by the entrance of head constraint 128 or inside.Now,
Central joint 120 provides support from the head E1 of driver and crew 132 vehicle front, therefore, and that is born comes from head
E1 loading can efficiently be absorbed.Therefore, head E1 is inhibited to the movement of vehicle front, for example, head can be prevented
Portion E1 is in contact with instrument board 102.Further, since central joint 120 is to engage central balloon 114 with main gasbag 112
, therefore, central balloon 114 can not constrain the head E1 and left shoulder E3a of driver and crew 132 to car medial movement.
Now the structure for central joint 120 is described further.Fig. 7 is to amplify the cushion pad exemplified in Fig. 4 (c)
108 and the figure of driver and crew 132.It is to regard vehicle fore-and-aft direction as Y-axis in the figure after Fig. 7；In being figure by vehicle front
Right is used as Y1；It is that left is illustrated as Y 2 in figure using rear view of vehicle.In addition, using above-below direction as Z axis, by car
Top is top Z1 in figure；It is that lower section is illustrated with Z2 in figure by under-vehicle.In addition, driver and crew's head in Fig. 7
Portion E1 is to contemplate to be exemplified what is come by the state that head constraint 128 suffers restraints.
As illustrated in Fig. 7, the vehicle of the lower end 121 at the centrally disposed junction surface 120 in upper end 119 of central joint 120
Front Y1 is right side in figure.Therefore, central joint 120 is upward, gets over to the inclined structures of vehicle front Y1.It is special
It is not that possess defined angle [alpha] 1 compared with imaginary line L2 along the imaginary line L1 of central joint 120 tilts to vehicle front Y1,
Imaginary line L2 is illustrated the above-below direction of the head E1 in the state of being suffered restraints by head constraint 128.Should
Tilt the consideration for being intended to further suppress to carry out the head E1 of driver and crew 132 injury values.
For example, when the head E1 of driver and crew 132 is in contact with the central joint 120 in said structure, head E1 from
Probably it is that the lower portion of nose 144 is first begin to contact near the jaw 142 of its underpart.That is, driver and crew 132 are not from top
The grade of forehead 146 start to be in contact with central joint 120., can be by avoiding the contact of the grade of forehead 146 according to this structure
To prevent the rear of head E1 from bending.Generally, bent after head E1 neck occurred on the contrary backward, it is attached to head E1 and neck
Near load is larger, and easily increases injury values.Central joint 120 in present embodiment, can be from head E1's
Bottom starts contact, prevents from bending after the E1 of head, so that injury values when reducing constraint.
