Abstract

A conveyance seat includes a seat frame, and a rod that extends to a region on a seat inside, and that is connected to the seat frame. The rod is connected to the seat frame via a shaft member. The shaft member includes a tubular portion having a through-hole, and a protruding portion protruding toward an outside in a radial direction from one end of the tubular portion in an axial direction. The shaft member is assembled to the seat frame in a state in which the tubular portion is inserted through the seat frame from a seat outside, and an insertion position of the shaft member in the axial direction is restricted by a position where the protruding portion abuts against an outside surface of the seat frame. The rod is inserted in the axial direction through the through-hole in the shaft member, and assembled to the shaft member.

First claim

What is claimed is:

1. A conveyance seat comprising:
a seat frame having side frames;
a rod that extends to a region on a seat inside;
a first shaft member and a second shaft member that connect the rod to the side frames of the seat frame, the first shaft member and the second shaft member each include:
a tubular portion that has a through-hole that extends in an axial direction through each respective shaft member; and
a protruding portion that protrudes toward an outside in a radial direction of each respective tubular portion from one end of the respective tubular portion in the axial direction;

a first link that one of the first shaft member and the second shaft member is inserted in; and
a second link that the other of the first shaft member and the second shaft member is inserted in, wherein
the first shaft member and the second shaft member are each assembled to the seat frame such that each respective tubular portion is inserted through a respective side frame of the side frames of the seat frame from a seat outside, and an insertion position of each respective shaft member in the axial direction is restricted by a position where each respective protruding portion abuts against an outside surface of the seat frame,
the rod is inserted in the axial direction through each respective through-hole of the first shaft member and the second shaft member and thereby assembled to the first shaft member and the second shaft member, and
the rod is located in the first shaft member and in the second shaft member such that the rod overlaps with and extends through the first link in a radial direction of the rod and such that the rod does not overlap with the second link in the radial direction of the rod.

2. The conveyance seat according to claim 1 , wherein
the rod extends between both side frames of the seat frame,
the rod includes end portions, and each end portion of the rod is connected to the corresponding side frame via the corresponding shaft member, and
each of the shaft members are substantially identical to each other.

3. A conveyance seat comprising:
a seat frame having side frames;
a rod that extends to a region on a seat inside;
a first shaft member and a second shaft member that connect the rod to the side frames of the seat frame, the first shaft member and the second shaft member each include:
a tubular portion that has a through-hole that extends in an axial direction through each respective shaft member; and
a protruding portion that protrudes toward an outside in a radial direction of each respective tubular portion from one end of the respective tubular portion in the axial direction;

a first link that one of the first shaft member and the second shaft member is inserted in; and
a second link that the other of the first shaft member and the second shaft member is inserted in, wherein
the first shaft member and the second shaft member are each assembled to the seat frame such that each respective tubular portion is inserted through a respective side frame of the side frames of the seat frame from a seat outside, and an insertion position of each respective shaft member in the axial direction is restricted by a position where each respective protruding portion abuts against an outside surface of the seat frame,
the rod is inserted in the axial direction through each respective through-hole of the first shaft member and the second shaft member and thereby assembled to the first shaft member and the second shaft member,
the rod is located in the first shaft member and in the second shaft member such that the rod overlaps with and extends through the first link in a radial direction of the rod and such that the rod does not overlap with the second link in the radial direction of the rod,
the rod extends between both side frames of the seat frame,
the rod includes end portions, and each end portion of the rod is connected to the corresponding side frame via the corresponding shaft member, and
each of the shaft members are substantially identical to each other.
