Embodiment Construction

[0074] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar extensions without violating the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0075] figure 1 It is an application schematic diagram of this embodiment—an overall view of a pretensioned seatbelt retractor, which can be applied to various occasions. This article takes an automobile as an example.

[0076] The pre-tensioned seat belt retractor (retractor for short) includes a retractor frame assembly 1-5, a reel 1-1, a base 1-2, a pre-tensioning device 1-3 and an auxiliary side cover 1- 4.

[0077] Such as figure 2 Shown is the structural diagram of the scroll 1-1. The reel 1-1 includes a reel bod...

Abstract

The invention provides a pre-tightening pipe applied to a pre-tightening safety belt. The outlet end of the pre-tightening pipe is connected with a pre-tightening pipe guide structure, the pre-tightening pipe guide structure is arranged at the outlet end of the pre-tightening pipe and can prevent a drive unit from deviating from one side of a preset path, and the work plane of the pre-tightening pipe guide structure is in smooth connection with the corresponding inner wall of the pre-tightening pipe. The pre-tightening pipe guide structure can guide the drive unit to accurately beat a pedal wheel, pre-tightening efficiency is improved, and stability of the whole pre-tightening pipe can be increased by connecting the pre-tightening pipe guide structure with other structures.

Description

technical field [0001] The invention relates to a pre-tightening safety belt, in particular to a pre-tightening tube applied to the pre-tightening safety belt. The invention also relates to a retractor and a safety device. Background technique [0002] Seat belts, as the basic protective device to protect drivers and passengers in the process of car collision, are important safety components of cars, and their quality is an important standard to measure car performance. [0003] The earliest safety belts applied to car seats are standard three-point safety belts, which restrict the user to the seat through a locking mechanism and webbing. However, this simple design has many drawbacks. [0004] First of all, due to the subjective factors of comfort and objective factors such as the thickness of the clothes and the elasticity of the webbing, after the seat belt is fastened, the webbing has a substantial tension margin relative to the user, which may cause the user to lose w...
