Description
Technical Field
The invention relates to an automobile safety airbag protection device, in particular to a T-shaped cylindrical central airbag.
Background
In a side collision of an automobile, passengers at the far end of the collision side can topple over to the collision side, so that the passengers and the driver collide with each other. The prior airbag technology has the technical proposal that one airbag is arranged between a front row driver and a passenger seat, and the prior airbag technology has the technical proposal that two airbags are arranged at the back of the front row driver and the passenger seat. The technical scheme of the single airbag only can weaken the movement trend of the passengers due to the weak structure and poor rigidity of the airbag after the airbag is vertically unfolded, and can not effectively block the movement of the passengers, so that the injury value of the passengers is larger. The technical proposal that two safety airbags are arranged at the chair back of the front row driver and passenger chair has the advantages of large volume, large occupied space and more uncertain factors of expansion in the expansion process, so the protection effect on passengers is poor, and the injury value of the passengers is larger. Thus, both of the above solutions have failed to meet the far end occupant protection requirements for side collisions by the european new vehicle evaluation code Euro NCAP.

The front and rear outer pull straps and the upper end of the extension part are fixed, so that the outer pull straps and the air bag form a stable triangle, and the head of a driver is effectively prevented from entering between the outer pull straps and the air bag in the movement process.
Further, the inner draw tape comprises an inner draw tape one and an inner draw tape two.
The first inner pull belt is provided with two transition parts which are bilaterally symmetrical, the front end of the first inner pull belt is connected with the front inner surface of the horizontal part of the air bag body, the rear end of the first inner pull belt is connected with the longitudinal part of the air bag body and the horizontal part of the air bag body, the second inner pull belt is provided with two transition parts which are bilaterally parallel, and the two ends of each inner pull belt are respectively connected with the left inner surface and the right inner surface of the longitudinal part of the air bag body.
Further, a plurality of vent holes are respectively arranged on the first inner pull belt and the second inner pull belt.
Further, a sleeve opening for installing the gas generator is arranged at the rear end of the longitudinal part of the gas bag body.
Further, the air bag body is mounted on the driver seat back toward the occupant side.
The invention has the beneficial effects that the air bag is unfolded to be in a T-column shape through the inner drawstring, the outer drawstring is obliquely arranged on the air bag body, so that the shape of the air bag body is firmly restrained, the movement of a driver is effectively prevented when the driver impacts the outer drawstring, the head, the neck and the chest of the driver can be effectively protected, and the legal requirements of European new vehicle evaluation standard EuroNCAP on the protection of remote passengers can be met.
