Abstract: A method for manufacturing a hollow spring member having a hollow steel spring rod having terminal sealed portions at both ends thereof. Each terminal sealed portion has a rotationally symmetric shape in which an axis passing through a center of the spring rod is an axis of symmetry. Each terminal sealed portion has an end wall portion including an end face; an arc-shaped smoothly curved surface between an outer peripheral surface of the spring rod and the end face, and a hermetically closed distal-end-center closure portion on the axis passing through the center of the spring rod. The method includes forming each of the end portions of the spring rod by forming a chamfered portion on an inner or outer peripheral side of the end portion of a hollow wire, the end portion having an opening portion at a distal end, heating the end portion of the hollow wire having the chamfered portion, and spinning the heated end portion to be gathered toward the axis from the outer peripheral side by a jig. The end wall portion, which includes the distal-end-center closure portion, is formed by the distal end of the end portion being joined together on the axis.

Abstract: In a vehicle seat frame, a connection member that connects left and right links together in a seat left-right direction is disposed below a rear portion of a cushion pan included in a seat cushion frame. A sloped surface sloped with a downward gradient toward a seat rear side is formed at a lower surface of the rear portion of the cushion pan. The sloped surface of the cushion pan slides in a seat rearward and diagonally downward direction relative to the connection member when the cushion pan deforms in a seat downward direction under load from the occupant during a head-on collision of the vehicle.
