Method of making cover fixing type pipe for safety belt

Abstract

The present invention relates to a method for manufacturing a pipe used in a safety belt. The method for manufacturing a cover fixing type pipe for a safety belt forms an opening groove at one side of the pipe bent in a shape of the pipe to be manufactured by using an opening groove punch and flattens an outer portion having the opening groove, thereby accurately obtaining a coupling position with a cover and simplifying a manufacturing process.

Description

technical field [0001] The present invention relates to a method of manufacturing a tube for a seat belt, that is, a method of manufacturing a seat belt tube of a cover fixing method, in which an open groove is formed on one side of the tube bent according to the shape of the tube to be manufactured by using an open groove punching machine , to flatten the outer part forming the open groove, so that the combination position with the cover is accurate, and at the same time, the manufacturing process is simple. Background technique [0002] In general, a seat belt for a vehicle mainly uses a three-point seat belt consisting of a lap belt wrapped around a passenger's waist to protect the passenger and a shoulder belt wrapped around a shoulder and chest area. The shoulder belt is combined with guide wheels, and the central pillar of the vehicle is equipped with a telescopic device for unwinding or winding the belt. The waist belt is usually installed on the door sill. [0003] ...
