Description
Technical Field
The invention relates to an automobile safety airbag structure, in particular to a wrapping and rolling type automobile safety airbag structure.
Background
Conventional airbags for manned vehicles are usually equipped with DAB, PAB, KAB, SAB, CAB, etc. for occupant protection in case of vehicle collision. DAB airbags are typically installed in the middle of the steering wheel of a vehicle, PAB airbags are typically installed in the instrument panel on the side of the front passenger of the vehicle, KAB airbags are typically installed at the instrument panel near the knees of the driver and front passenger, SAB airbags are typically installed at the seat back of the driver and passenger of the vehicle, and CAB airbags are typically installed above the side windows of the vehicle. With the popularization of the automatic driving automobile, the steering wheel driven by a person is not required for the completely automatic driving automobile, and the internal structure and the passenger protection mode of the automobile are also greatly changed. Although the impact damage value between the vehicle body and the passenger during the vehicle collision can be reduced by the flexible design of the vehicle interior trim, the airbag protection is still required to reduce the impact damage value between the passenger and the passenger during the vehicle collision. The conventional air bag for a manned vehicle has failed to satisfy the structural mounting requirements and occupant protection requirements for an autonomous vehicle, and it is required to develop a new air bag that satisfies the structural mounting requirements and occupant protection requirements for an autonomous vehicle.
Disclosure of Invention
The invention aims at the problems and provides a wrapping and rolling type automobile safety air bag which is arranged on an automobile passenger seat. When the automobile collides, the safety air bag is unfolded around the trunk of the passenger, so that collision damage values between the passenger and between the passenger and the automobile interior are reduced, and the collision safety of the automatic driving automobile is met.
The technical scheme of the invention is as follows:
a wrap-and-roll type airbag structure is characterized in that: the two groups of the automobile safety air bags are two in each group, one safety air bag in the first group is respectively arranged on two sides of a chair back framework of a passenger seat, and the other safety air bag in the second group is respectively arranged on two sides of a seat cushion framework of the seat; when the automatic driving automobile collides, the four air bags are simultaneously detonated, and air bags of the safety air bags are unfolded around the upper trunk and knees of a passenger to form two groups of wrapping shapes, so that the passenger is protected.
More preferably, the first two airbags attached to the both sides of the seat back frame have their upper torso-protecting bags deployed and then wrapped around the upper torso of the occupant to protect the chest, the rib, and the shoulder of the occupant.
More preferably, the knee and lower leg protection airbags of the two airbags two attached to both sides of the seat cushion frame are deployed and then wrapped around the knees and lower legs of the occupant to protect the knees and lower legs of the occupant.
Preferably, the upper torso protection air bags are formed by sewing an upper air bag outer bag sheet, an upper air bag inner bag sheet and an upper air bag outer pull belt in order to realize the bending expansion of two upper torso protection air bags for protecting passengers and two knee and shank protection air bags; the knee and shank protecting air bag is formed by sewing a lower air bag outer bag sheet, a lower air bag inner bag sheet and a lower air bag outer stretching belt.
Further preferably, the surface of the upper airbag inner sheet is folded by a fold line and sewn by a sewing thread to form a plurality of folds, and each fold is provided with an outer pull belt passing hole; the opposite ends of the upper air bag outer bag sheet and the upper air bag inner bag sheet are overlapped and sewn by sewing threads to form an air bag mounting upper fixing part, a gas generator mounting opening is reserved after sewing, and the upper air bag outer bag sheet and the periphery of the upper air bag inner bag sheet are sewn to form an air bag body; the upper air bag outer stretching strap penetrates through the outer stretching strap passing hole on the folds of the upper air bag inner bag sheet, and two ends of the upper air bag outer stretching strap and the folds of the two ends of the upper air bag inner bag sheet are sewn together by outer stretching strap sewing threads; the bending radian of the upper trunk protection air bag is influenced by pre-adjusting the length of the pull belt outside the upper air bag, so that the proper bending radian of the upper trunk protection air bag is realized, and finally, the wrapping and rolling type structure of the first safety air bag is realized.
Further preferably, the surface of the lower air bag inner bag sheet is folded by a fold line and sewn by a sewing thread to form a plurality of folds, and each fold is provided with an outer pull belt passing hole; the opposite ends of the lower air bag outer bag sheet and the lower air bag inner bag sheet are overlapped and sewn by sewing threads to form an air bag mounting lower fixed part, a mounting opening of the gas generator is reserved after sewing, and the peripheries of the lower air bag outer bag sheet and the lower air bag inner bag sheet are sewn to form an air bag body; the lower air bag outer stretching strap penetrates through an outer stretching strap passing hole on the folds of the lower air bag inner bag sheet, and two ends of the lower air bag outer stretching strap and the folds of the two ends of the lower air bag inner bag sheet are sewn together by outer stretching strap sewing threads; the bending radian of the knee and lower leg protection air bag is influenced by pre-adjusting the length of the lower air bag outer stretching strap so as to realize the proper bending radian of the knee and lower leg protection air bag, and finally the wrapping and rolling structure of the second safety air bag is realized.
The invention has the beneficial effects that:
when the automatic driving automobile collides, the 4 safety airbags are simultaneously detonated, the two airbags are unfolded and wrapped around the upper trunk of the passenger, and the two airbags are unfolded and wrapped around the knees of the passenger, so that the injury values of the chest, the rib, the shoulder, the knee and the lower leg of the passenger when the passenger collides with the passenger and the passenger collides with the automobile body are reduced.
