Welding method for car seat

Abstract

The invention discloses a welding method for a car seat. The welding method is characterized by comprising welding the car seat. The car seat comprises a backrest framework, wherein a seat frame is arranged at the lower part of the backrest framework; the backrest framework comprises a bottom rod, a left side rod, a right side rod, an upper sinuous spring, an upper retaining ring, a left sinuous spring, a right sinuous spring, a left retaining ring and a right retaining ring; and all of the retaining rings and connecting rods are made of flexible materials. The welding method comprises mounting the upper sinuous spring and the upper retaining ring, mounting the upper sinuous spring together with the upper retaining ring at the top of the left side rod and the top of the right side rod, mounting the left sinuous spring and the right sinuous spring, integrally forming the left retaining ring and the right retaining ring respectively with the connecting rods connected therewith, respectively mounting the connecting rods together with the left retaining ring the right retaining ring, and welding the bottom rod of the backrest framework to the rear side of the seat frame. The welding method for the car seat can solve the problems of difficult welding, uncomfortable use and high consumption of materials of rear seats in the prior art.

Description

technical field [0001] The invention relates to the technical field of automobile seat manufacturing, in particular to a welding method for rear seats. Background technique [0002] At present, the backrest frame assembly of the rear seats generally includes three adjacent backrest frames, wherein the horizontally arranged snake springs in each backrest frame are fixed by a fixer, and the backrest frame includes two left and right side bars, two The upper ends of the side bars are equipped with upper bent pipes, the lower ends of the two side bars are equipped with lower bent pipes, and the side bars are provided with lumbar supports on the upper parts of the lower bent pipes. The amount of welding of such rear seats is very large, and there are many welding dead angles, which makes welding difficult; it is also very uncomfortable to use, and the transition between the three seats is also very uneven and comfortable, and the amount of snake springs Also bigger, material con...
