Abstract
A vehicle seat includes a link mechanism for liftably connecting a seat cushion to a support base directly or indirectly mounted to a vehicle body. The seat cushion is composed of a seating frame with side frames arranged at both right and left ends. The link mechanism includes link members connecting the support base and side frames, and a link connecting member connecting the link members together. Flange portions are formed at both end portions of the extending direction of the link connecting member. End surfaces of the extending direction of the flange portions and facing surfaces of the link members facing the end surfaces are abutted, and the end surfaces and the facing surfaces are joined by welding.

7. A method for manufacturing a vehicle seat comprising a link mechanism for liftably connecting a seat cushion to a support base directly or indirectly mounted to a vehicle body, the method comprising:
-
connecting link members constituting the link mechanism to side frames arranged at both right and left ends, which constitute a seating frame becoming a frame of the seat cushion; forming flange portions by connecting the link members together, pressing end portions of a link connecting member having the end portions widening into a tapered shape to the link member side against facing surfaces of the link members facing the end portions, and flexibly deforming the end portions to be parallel to the facing surfaces; joining end surfaces of the flange portions and the facing surfaces of the link members by welding in a state of being abutted; and connecting the link members to the support base. - View Dependent Claims (8)
