Height adjustment structure for safety belt and safety belt

Abstract

The invention provides a height adjustment structure for a safety belt and the safety belt. The height adjustment structure comprises a sliding rail, a frame rack, locking blocks, locking block supporting columns, a locking block adjusting limit groove, locking teeth, a tooth-shaped rail, a spring limit column, a spring and a screw cap. The limit groove and a guide groove can both contain the locking blocks. When the locking block supporting columns are in the limit groove, the locking teeth are separated from the tooth-shaped rail, and the frame rack can move up and down along the sliding rail. When the locking block supporting columns are in the guide groove, the locking teeth are matched with the tooth-shaped rail, and the frame rack is static relative to the sliding rail. Due to the fact that the frame rack can move up and down along the sliding rail, one end of the safety belt can be connected with the frame rack, and the adjustment of the safety belt height can be achieved. The height adjustment range of the safety belt can be further satisfied according to actual need by designing the length of the sliding rail to satisfy requirements of people with different height. According to the safety belt with the height adjustment structure, the height adjustment range is wide, and the universality is better.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a height adjustment structure for a safety belt and the safety belt. Background technique [0002] In order to ensure the safety of the people in the cab of the car, the cab of the car is equipped with a safety belt. The seat belt has two ends, which are respectively fixedly connected to the interior of the car. When the vehicle is running, the person in the car can fasten the seat belt to the body.
