Description

Safety belt height adjusting mechanism Technical Field The utility model relates to the technical field of safety belts, in particular to a safety belt height adjusting mechanism. Background The safety belt is a safety device used on vehicles such as vehicles, and mainly has the function of restraining drivers and passengers on the seat when the vehicles collide, sudden braking and other emergency conditions occur, so that the collision between the passengers and hard objects in the vehicle or the collision between the passengers and the hard objects out of the vehicle caused by impact force generated by inertia is avoided, and the casualty risk is effectively reduced. The safety belt is characterized by generally comprising a braid, a retractor, a fixed point, a lock tongue, a fastener and the like, wherein the braid is a part for directly restraining a human body, the retractor can automatically retract and release the braid, the fixed point is used for fixing the safety belt on a vehicle body, and the lock tongue and the fastener are used for connecting and disconnecting the braid. In order to adjust the fixing position of the webbing on the vehicle body pillar, the relative position of the webbing and the body of the driver is changed, and a webbing height adjusting mechanism is usually provided. Most of the existing safety belt height adjusting mechanisms adopt a clamping groove type structure, and the clamping groove type structure realizes height adjustment by clamping the adjusting sliding blocks into clamping grooves with different heights. However, the height adjusting mechanism of the slot type safety belt can only support limited-level height adjustment and cannot completely match drivers with different height and body types, and certain limitation exists. Disclosure of utility model In order to solve the technical problems, the utility model provides a safety belt height adjusting mechanism for realizing stepless adjustment of the height of a safety belt and adapting to different drivers and passengers.
