Description

Technical Field

[0001] The utility model relates to a tool for measuring the H point of a car seat. Background Art

[0002] Car seats are important facilities that affect driving and riding safety and comfort. They can be divided into split seats and long seats according to their shape. The H-point refers to the connection point between the human torso and thigh in a two-dimensional or three-dimensional human body model template, that is, the hip point; in the human body template, it is the hip joint, which represents the reference position of the midpoint of the hip joint in the car seat after the driver or passenger takes the seat. When the driver or passenger takes the seat, most of the body weight is applied to the seat cushion through the buttocks, a part is borne by the backrest through the back, and a small part is applied to the steering wheel and floor through the left and right hands and feet. In this sitting position, the upper body movement of the driver or passenger must rotate around the horizontal axis of the H-point. Therefore, the position of the H-point determines the convenience of upper body movement and riding comfort. Therefore, after the car seat is designed and the sample is produced, the H-point of the car seat must be measured and marked.

[0003] In order to accurately measure the H-point of a car seat, the car seat must be fixed with the help of a matching positioning device. However, the stability of existing car seat positioning devices is low, and the fixation of the car seat is not firm enough. The reason is that the number of fixing points is insufficient and the position distribution is not comprehensive enough, which causes the car seat to shake easily, thereby affecting the smooth progress of the measurement. In addition, the positioning accuracy is also low, so the car seat cannot be accurately positioned, resulting in low measurement accuracy of the car seat H-point, which needs further improvement.
