In order to give full play to the safety role of seat belts at the end of this year, the following items should be paid attention to when installing seat belts.
(1) Installation of waist belt. When installing the waist belt, it should be noted that the two fixed points of the waist belt should be high on the body floor, seat frame or side wall of the body (most of them are on the floor). The position of the fixed point on the floor is related to the hip point of the person sitting on the seat. The angle between the waist belt fixing point and the side line of point H and the horizontal datum of the car body should be 450 as much as possible. In addition, in all positions within the adjustable seat adjustment range. This included angle must be within the range of 20750.
(2) Installation of shoulder strap. The position range of the upper fixed point of the shoulder strap has been stipulated by the civil industry in the relevant standards and should be implemented in accordance with it. The distance between the shoulder strap fixing point and the center line of the seat shall not be less than 140mm.
(3) Installation of accessories. The proper location of the attachment is one of the important conditions for determining whether the seat belt can effectively play a role. It is generally required that the lateral distance between the two lower mounting accessories of two-point and three-point safety belts should not be 350mm, and the distance between these two mounting accessories and the center line of the seat should be as equal as possible.
