Description
Technical Field
The invention belongs to the technical field of automobile parts, and particularly relates to a side airbag structure of an automobile seat.
Background
With the continuous improvement of the consciousness of Chinese people on the safety of automobiles, an automobile safety index mechanism is newly established in recent two years. Because of the great difference of the evaluation methods of various organizations, various host plants face more difficulty and challenge in the development and design of new vehicle models. The C-NCAP assessment comprises: the front crash was 50 km FRB and 50% 50 km MPDB, and the side crash was 50 km AE-MDB (bogie weight 1400 Kg). The C-IASI assessment comprises: the front collision is 25% of 64 km ODB, and the side collision is 50 km MDB (trolley weight is 1500 Kg). Besides the difference of the whole vehicle collision form, the two evaluation methods also have great difference in the injury indexes and evaluation definitions of the test dummy and the dummy. For example, the differences between C-NCAP side impact and C-IASI side impact are mainly: the weight of the trolley is different from 100 kg; the shape, size and material design of the collision blocks are different; the positions of the trolley impact test vehicles are different (including the X direction and the Z direction); fourthly, different dummy persons are placed in the main driver seat, the side collision of C-NCAP is a 50-percentile WorldSid dummy, and the side collision of C-IASI is a 5-percentile SidIIs (D edition) dummy; the injury index and evaluation definition of each body part of the dummy are also different. Thus, side impact development requires balancing the vehicle body structure and seat side airbag design. The Worldsid dummy is larger in size, the SidIIs (D edition) dummy is smaller in size, and the height of the dummy in sitting posture is greatly different. Thus, when side collision happens, the door plate armrest extrudes the seat side air bag to move towards the inside of the vehicle, and the relative position is in a staggered state because the Worldsid sitting posture is high, and the lower rib is higher than the door plate armrest. Thus, the door panel arm rests compress the seat side air bag and the WorldSid dummy thorax is much less affected. However, SidIIs (D edition) dummy has a low sitting posture, and the lower rib and the door plank support an overlapping area. Thus, the door plate armrest presses the seat side air bag, and the chest of the SidIIs (D edition) dummy is greatly influenced. The middle area of the air bag can extrude the rib pressure sensor at the lower part of the chest to increase the chest pressure in the air leakage process, so that the chest of a driver is greatly injured.
In the current automobile on the market, the structural design form of the side airbag of the automobile seat is mainly a round cake-shaped airbag, and the air release hole is a round hole or a long seam hole and is not provided with a drawstring. The main technical defects of the disk-shaped air bag are that the rigidity distribution of each area is almost the same and the thickness of each area is almost the same in the process of explosion, ejection and air leakage of the air bag. Therefore, the air bag is difficult to reduce the injury value of each part of the body of the driver and the passenger to the maximum extent, and the driver and the passenger cannot be effectively protected. In the side impact development of various main engine plants at present, in order to meet the development target of the safety performance of the whole automobile, the side structure of the automobile body is generally strengthened or the door panel and the side wing of the seat are sacrificed. Thus, the door plate shape arrangement and the light weight design of the vehicle are not facilitated. And greatly increase development costs and weight.
