Installation structure of a car seat belt retractor

Abstract

The invention discloses an automobile safety belt retractor installation structure and belongs to the technical field of automobile body accessories. The automobile safety belt retractor installation structure comprises a safety belt retractor support and safety belt retractor support reinforcing plates. The safety belt retractor support, the safety belt retractor support reinforcing plates and an automobile body B-pillar inner plate are connected together through three-layer welding spots. The safety belt retractor support and the automobile body B-pillar inner plate are further fixedly connected through other two-layer welding spots. The safety belt retractor support reinforcing plate and an automobile body B-pillar inner plate reinforcing plate are fixedly connected through other two-layer welding spots. The automobile safety belt retractor installation structure has the advantages of being simple in structure, low in cost, convenient to install and beneficial to engineered mass production; in addition, the automobile safety belt retractor installation structure meets installation requirements of an automobile safety belt retractor, improves rigidity of the safety belt retractor support, avoids the phenomenon of sudden spontaneous firing of side air bags and improves safety in automobile driving.

Description

technical field [0001] The invention relates to an automobile safety belt, in particular to a retractor installation structure suitable for the automobile safety belt, and belongs to the technical field of automobiles. Background technique [0002] The car seat belt is a device installed on the car body to ensure the personal safety of passengers and drivers. When a high-speed vehicle collides, the car body stops moving quickly, and the passenger's body will continue to move forward due to inertia. When it collides with the vehicle body, it may smash the windshield and fly out of the window in severe cases. Therefore, in order to prevent similar injuries from colliding, the public security department requires that the driver of a small bus and the passengers in the front row must use safety belts. In high-end cars, in addition to the front and rear seats are equipped with seat belts, an airbag system is also installed. The airbag system transmits the induction signal to the...

Problems solved by technology

At present, there are many ways to install seat belt retractors, but basically they are assembled through seat belt retractor brackets and body B-pillars or floor side beams. During the use of seat belts, the retractor brackets are frequently installed. Therefore, it will pull the floor side beam or the inner panel of the B-pillar to produce plastic deformation, which will cause the seat belt to fail to return; in addition, the side impact sensor of the airbag system is also installed on the inner panel of the B-pillar, which is located in the bracket of the seat belt retractor. Nearby, when the seat belt retractor bracket is stressed, the stability of the installation point of the side impact sensor will be greatly reduced, and there is a risk of side airbag detonation due to misjudgment by the airbag ECU control unit
