Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] The assembly process of the safety belt and the safety belt retractor is characterized in that it comprises the following steps:

[0027] Step 1. Fix the seat belt retractor on the auxiliary tooling, so that the included angle between the axis of the movable guide of the seat belt retractor and the axis of the mandrel through hole is an obtuse angle; the included angle described in the present invention is 150 °-179°.

[0028] Step 2, passing the end of the safety belt through the movable guide and the through hole of the mandrel in turn;

[0029] Step 3, bending the end of the safety belt to form a folded portion;

[0030] Step 4. Sew the end of the folded part to the safety belt to form a piercing part;

[0031] Step 5. Insert the locking rod into the piercing part, and withdraw the safety belt, so that the locking rod and the end of the through hole of the...

Abstract

The invention belongs to an automobile part production process, and particularly relates to an assembly process of a safety belt and a safety belt winder. The assembly process has the advantages that the assembly process of the safety belt and the safety belt winder is improved; the assembly process of firstly connecting the safety belt onto the safety belt winder in a penetrating way and then sewing the end part of the safety belt is adopted; the problem of assembly difficulty of the safety belt and the safety belt winder in the prior art is solved; the work difficulty of workers is reduced; and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the production process of auto parts, in particular to an assembly process of a seat belt and a seat belt retractor. Background technique [0002] Seat belt devices for automobiles include webbing retractors, and there are many types of webbing retractors. Among them, webbing retractors with pre-tensioning functions can eliminate the slack between the webbing and the occupant in a collision accident, It reduces the relative motion between the occupant and the vehicle body, and has an obvious protective effect on the occupant's chest and abdomen, and has been extensively studied. [0003] In the production process of the seat belt retractor in the prior art, the end of the seat belt is first bent and then stitched to form a sleeve, and then the sleeve is manually passed through the guide on the retractor. device, then pass through the through hole of the mandrel of the retractor, and finally perform a fixation by snapping the f...
