Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See Fig. 1 ~ 3, a kind of occupant protection system is provided to the utility model embodiment and is described in detail.A kind of occupant protection system that the utility model embodiment provides is located on safety chair seats of car; described seat comprises the chair back 3 and vehicle seat support; wherein said vehicle seat support comprises the chair cushion 4 of skeleton and the described skeleton of parcel; the occupant protection system of the present embodiment is located in described vehicle seat support; comprise air bag 2 and gas generator 6, wherein:
Described gas generator 6 is connected on the crossbeam 5 of described skeleton.
Described air bag 2 is connected with described gas generator 6, launches by described gas generator 6 inflation.On described chair cushion 4, relatively described air bag is provided with opening 7.When not inflating, described air bag 2 folding shrinking is inside chair cushion 4; When automobile collides, described air bag 2 by described gas generator 6 inflating expanded the and outside face stretching out in chair cushion 4 from described opening 7 directly to contact and occupant's thigh 1 lifted.
In the present embodiment, weakening region is provided with around described opening 7, namely carry out local weakness to around opening 7, around automobile collision procedure split shed 7, ratio is easier to tear, thus guide air bag 2 to detonate from tear place, guarantee that air bag 2 launches completely within the shortest time, thus be beneficial to described air bag 2 launch inside chair cushion 4 eject.
As shown in Figure 1, when described air bag 2 is inflating expanded and in similar triangular prism shape after stretching out from described opening 7 by described gas generator 6.Wherein, the medial surface of described triangular prism 201 is fitted with the outside face of described chair cushion 4, and two other side 202,203 of described triangular prism is respectively towards to support occupant's thigh 1 and shank, and the region 204 that described two sides are intersected contacts inside the knee joint of occupant.Therefore, when head-on crash accident occurs, described air bag 2 is inflating expanded and can not only lift occupant's thigh 1 after described opening 7 stretches out by described gas generator 6, and be equivalent to form a large buffering pneumatic cushion at occupant's hip position, occupant's hip is subject to the constraint of buffering pneumatic cushion, can not continue forward slip, thus is subject to good constraint, and greatly reduce the contact force of occupant's chest, head and other parts, thus safety factor significantly improves.
The highest expansion pressure of the gas that gas generator 6 of the present utility model produces should be greater than 160kPs, and opening completely for air bag 2 provides sufficient pressure, ensures that air bag 2 can be opened fast.
See Fig. 3, the gas generator 6 of the occupant protection system that the utility model provides is electrically connected the ECU20 of automobile, and ECU20 is electrically connected sensor (the present embodiment comprises impact strength sensor 22 and collision protection sensor 21).ECU20 judges vehicle collision intensity according to the information that sensor detected vehicle transmits, and when impact strength reaches setting safety value, sends instruction, thus start described gas generator 6 and inflate to described air bag 2 to gas generator 6.
Understandable, sensor of the present utility model can be multiple sensors, such as speed, acceleration/accel etc.In this example, sensor comprises the impact strength sensor 22 being arranged on automotive front, detects the deceleration/decel of automobile.The deceleration/decel detected is sent to ECU20 by impact strength sensor 22.ECU20 is preset with deceleration/decel threshold values, in the collision detection process that impact strength sensor 22 sends by ECU20, the deceleration/decel of automobile compares with the deceleration/decel threshold values preset, draw the severity of collision, when the deceleration/decel that the impact strength sensor 22 that ECU20 receives sends exceedes default deceleration/decel threshold values, then send instruction to gas generator 6, start described gas generator 6 to inflate to described air bag 2, thus make described air bag 2 stretch out in chair cushion outside face directly to contact and to be lifted by occupant's thigh from described opening part in inflation process.。
In addition, the sensor of the present embodiment can also arrange collision protection sensor 21, and collision protection sensor 21 is substantially identical with the structural principle of impact strength sensor 22, is also for the deceleration/decel got is sent to ECU20.Unlike, the deceleration/decel threshold values that ECU20 sets for collision protection sensor 21 is different with the deceleration/decel threshold value set for impact strength sensor 22.Therefore, the collision protection sensor 22 of the present embodiment be with impact strength sensor 21 with the use of, according to the combination of two sensor detection information, ECU20 judges whether that starting described gas generator 6 inflates to described air bag 2, prevents impact strength sensor 21 from causing anti-operation because of accidental short circuit.So the arranging of collision protection sensor 22 can increase the accuracy that the utility model controls, the unexpected situation of opening of described gas generator 6 is avoided to occur.
Embodiment of the present utility model discloses a kind of safety chair seats of car, comprises vehicle seat support and occupant protection system as shown in Figure 1.
In sum, occupant protection system disclosed in the utility model and safety chair seats of car are by being arranged on the chair cushion inner front side of vehicle seat support by air bag, on described chair cushion, relatively described air bag is provided with opening, described air bag is inflating expanded and stretch out in chair cushion outside face directly to contact and to be lifted by occupant's thigh from described opening part by described gas generator, and the air bag stretching out chair cushion outside face is triangular prism shape, occupant's hip is subject to the constraint of air bag, forward slip can not be continued, thus receive good constraint, and greatly reduce occupant's chest, the contact force of head and other parts, thus safety factor significantly improves.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
