Abstract
The present invention relates to a method of welding an upper rail of a seat track for vehicle seat and adapter bracket for supporting a seat frame, the method comprising: contacting surface-to-surface a lower surface of a planar coupling surface part which constitutes a lower end part of the adapter bracket and extends in a longitudinal direction to a predetermined length onto an upper surface of a planar horizontal surface part which constitutes an upper end part of the upper rail and extends in the longitudinal direction; and joining the coupling surface part and the horizontal surface part by welding a lower surface of the horizontal surface part where the horizontal surface part is overlapped with the coupling surface part. Therefore, welding strength between the upper rail of the seat track and the adapter bracket can be reinforced and working hours required to the welding job can be remarkably decreased compared to a conventional art where the welding was performed along an edge of the coupling surface part.
