Abstract

The invention discloses a self-locking height adjuster which comprises a guide rail. Two sides of the guide rail are provided with racks. The adjuster also comprises a sliding block connected with the guide rail in a sliding mode, wherein two gears are arranged on the sliding block, the two gears are meshed with the racks respectively, and a gap is formed between the two gears; and a locking assembly arranged on the sliding block and comprises a locking block, wherein the locking block slides relative to the sliding block to be clamped into or slide out of a gap between the two gears so as to lock or unlock rotation of the gears. In the application, the locking force of the locking block on the gear can be increased along with the increase of the stress of the gear, so that the danger caused by locking failure due to excessive instant stress of the height adjuster when an automobile accident occurs can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobile safety belts, in particular to a self-locking height adjuster. Background technique [0002] With the popularity of automobiles, the safety of automobiles has become a concern for drivers and passengers. The existing seat belt buckle has a strong locking force, which can ensure the safety of the seat belt; in order to cooperate with drivers and passengers of different sizes, a height regulator is also provided on the car to adjust the height of the seat belt. [0003] The current safety belt height adjuster has the following defects: first, the existing height adjuster is mostly locked by the form of a protrusion falling into a groove, and the locking force is relatively small. In the event of a driving accident, the height adjuster of the seat belt is suddenly subjected to a large force, and the protrusion in the locking mechanism is forced out of the groove, resulting in the failure of the l...
