Abstract

The invention discloses an arrangement method and checking method of the lower fixed point of a safety belt. The arrangement method comprises the following steps: S1, confirming the limit positions of an H point in a motion region; S2, making a permissible region (P3) satisfying preset requirements at each limit position; S3, arranging the lower fixed point (P) of the safety belt in the crossed region (P5) of the permissible region (P3) corresponding to the limit positions. Through the arrangement method disclosed by the invention, the crossed region of all the permissible regions corresponding to the limit positions can be quickly and correctly confirmed, and the lower fixed point of the safety belt is arranged in the crossed region, so that the lower fixed point of the safety belt can be guaranteed to satisfy the preset requirements.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a method for arranging fixed points under a safety belt and a checking method. Background technique [0002] The fixed points under the car seat belt need to be designed to meet the legal requirements of the target country. Take the national standard as an example: the national standard GB14167-2013 stipulates that all positions of the front seats of M1 vehicles must meet the requirements: α1 angle of the non-buckle side should be within the range of 30°~80°, α2 (buckle side) It should be within the range of 45° to 80° (the angles α1 and α2 both refer to the angle between the line connecting the lower fixed point of the seat belt and point H (point H is the hinge center of the human trunk line and the center line of the thigh bar) and the horizontal line ). [0003] In the prior art, there is no method for quickly and accurately determining the position of the fixed point under the safe...
