seat belt height adjuster

Abstract

The invention discloses a safety belt height adjuster and belongs to the technical field of automobiles. The safety belt height adjuster comprises a sliding rail and a sliding piece arranged on the sliding rail in a sliding mode, and multiple gear grooves formed up and down are formed in the sliding rail. The sliding piece is connected with a safety belt and comprises a sliding block, a gear piececapable of extending into and out of the corresponding gear groove and a gear shifting control piece fixedly connected with the sliding block. At least one end of the gear piece is magnetic, and themagnetic end extends into an inner cavity of the gear shifting control piece. Two movable magnetic bodies are arranged in the inner cavity of the gear shifting control piece, and the magnetic poles, near the gear piece, of the two magnetic bodies are different. The safety belt height adjuster has the beneficial effects of being simple in structure, easy to operate and convenient to adjust; and gear shifting is achieved through the gear shifting control piece, and the two magnetic bodies are arranged in the gear shifting control piece to be opposite to the magnetic gear piece alternately so asto correspond to the states of the gear piece extending into and out of the corresponding gear groove.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a safety belt height adjuster. Background technique [0002] Car seat belts are an indispensable part of the passive safety system of cars. Three-point safety belts are usually used in existing auto parts; The first fixed point is usually fixed under the B-pillar of the vehicle body and on the side of the seat to constrain the occupant's hip position, and the third fixed point is usually fixed on the B-pillar of the vehicle body to provide restraint for the shoulders of the occupant. The ideal position is that the shoulder belt of the seat belt can just be located in the middle of the passenger's shoulders, but due to the difference in the size of the passengers, the fixed upper fixing point cannot meet the requirements of all target groups. [0003] Therefore in the design of existing automobile seat belt generally be to design upper fixed point to be highly adjustable, hav...
