Abstract

A vehicle seat frame that uses one spacer to enable maintaining of positional relationship between three components is provided. The vehicle seat frame comprises a rod; a first frame; a second frame that comprises a first open hollow for the rod to pass through and extends to cross a rod axis; a third frame that extends to cross the rod axis; and a spacer that comprises a first spacer portion that is disposed between and contactable to the first frame and the second frame, and a second spacer portion that extends from the first spacer portion, passes through a second open hollow disposed in the second frame towards a third frame, and has an extending end that is contactable to the third frame.

First claim

What is claimed is:

1. A vehicle seat frame that configures a framework of a vehicle seat, the vehicle seat frame comprising:
a rod;
a first frame that is disposed in a first axial end of the rod and extends to cross a rod axis;
a second frame that is disposed closer to a second axial end of the rod than the first frame is, comprises a first open hollow for the rod to pass through, and extends to cross the rod axis;
a third frame that is disposed closer to the second axial end of the rod than the second frame is and extends to cross the rod axis; and
a spacer that comprises:
a first spacer portion that is disposed between and contactable to the first frame and the second frame; and
at least one second spacer portion that extends from the first spacer portion towards the third frame, passes through a second open hollow disposed in the second frame, and has an extending end that is contactable to the third frame.

2. The vehicle seat frame according to claim 1 , wherein
the first open hollow comprises a through hole that surrounds an outer circumference of the rod;
the second open hollow comprises a recess that is sunken radially outwardly from a periphery of the first open hollow;
a first distance, which is a distance between the first frame and the second frame, is greater than a second distance, which is a distance between the second frame and the third frame;
the first spacer portion comprises a hollow cylinder though which the rod is inserted; and
the at least one second spacer portion comprises an extended portion extending from a part of an end of the first spacer portion along the rod axis.

3. The vehicle seat frame according to claim 1 , wherein
at least a part of a periphery of the first open hollow is welded to the rod; and
the first frame and the third frame are rotatable about and relative to the rod.

4. The vehicle seat frame according to claim 3 , wherein
the first frame is a side frame that is a part of a cushion frame;
the second frame is a tilt link that is a part of a tilt mechanism for tilting a front end of a seat cushion;
the third frame is a lifter link having a first end coupled to the rod and a second end coupled to a vehicle to support the cushion frame;
the rod transmits a rotational force to the second frame;
the third frame is situated closer to the center of a seat than the second frame is along a seat-width axis; and
the first frame is situated closer to an end of the seat than the second frame is along the seat-width axis.

5. The vehicle seat frame according to claim 1 , wherein the first spacer portion and the at least one second spacer portion are made of metal and integrally formed.
