A rear link assembly for a vehicle seat, comprising;
- a pipe provided with a first and a second stop protrusion portions in a vicinity of each end thereof;
- a link bracket fixed between the first and second stop protrusion portions;
- a serration formed by repeatedly forming pluralities of protrusions and depressions on an inner circumferential surface of a coupling hole of the link bracket into which the pipe is inserted;
- stepped portions formed on the protrusions;
- and
- a first introduced volume portion formed in such a manner that one side of the second stop protrusion portion is deformed and introduced into the stepped portions.
A method of manufacturing a rear link assembly for a vehicle seat, comprising:
- a first swaging step of forming a first stop protrusion portion in a portion in a vicinity of each end of a pipe;
- a link bracket installation step of installing a link bracket at the end of the pipe so that one side of the link bracket is supported on the first stop protrusion portion;
- a second swaging step of forming a second stop protrusion portion configured to come into close contact with a remaining side of the link bracket;
- and
- a step of forming a first introduced volume portion in such a manner that the second stop protrusion portion is deformed and introduced into the stepped portions formed in the protrusions of the serration formed on a coupling hole of the link bracket.
