Abstract
A frame structure of a seat cushion can include a right and left plate-like side panel having side portions of the seat cushion, and a tubular front pipe reinforcing front side portions of the right and left side panels. The front pipe can include right and left erect portions extending over the length of front sides of the side panels, right and left extending portions extending forward from upper end portions of the right and left erect portions, and a bridge portion bridging across front end portions of the right and left extending portions.
Claims19
A frame structure of a seat cushion for a vehicular seat, comprising:
- a right plate-like side panel and a left plate-like side panel constituting side portions of the seat cushion;
- a tubular front pipe reinforcing front side portions of the right plate-like side panel and the left plate-like side panel,
- wherein the front pipe includes:
- a right erect portion and a left erect portion, the right erect portion and the left erect portion respectively extending substantially over an entire length of a front side of the right plate-like side panel and a front side of the left plate-like side panel so as to protrude above each plate-like side panel, and the right erect portion and left erect portion being oriented in a first plane,
- a right extending portion and a left extending portion extending forward from an upper end portion of the right erect portion and an upper end portion of the left erect portion, respectively, the right extending portion and the left extending portion being oriented in a second plane, and the first plane and the second plane being oriented substantially perpendicular to each other, and
- a bridge portion bridging a front end portion of the right extending portion and a front end portion of the left extending portion;
- and
- a horizontally extending rod having a longitudinal axis extending in a direction that a longitudinal axis of the bridge portion extends such that the horizontally extending rod is mounted between a front portion of the right plate-like side panel and a front portion of the left plate-like side panel.

A frame structure for a vehicular seat, comprising:
- a right side panel and a left side panel;
- a front rod extending between a front side portion of each panel;
- a rear rod extending between a back side portion of each panel;
- a front pipe proximate to and in front of the front rod in a front-rear vehicular seat direction, wherein the front pipe includes:
- a right side erect portion and a left side erect portion, the right side erect portion and the left side erect portion extending upward to a right side extending portion and a left side extending portion, respectively, each extending portion extending in a direction away from the front rod, the right side erect portion and left side erect portion being oriented in a first plane, the right side extending portion and the left side extending portion being oriented in a second plane, and the first plane and the second plane being oriented substantially perpendicular to each other,
- a bridge portion horizontally extending between the right side extending portion and the left side extending portion;
- a right side connection member and a left side connection member connecting the front pipe to the right side panel and the left side panel, respectively;
- and
- a horizontally extending rod having a longitudinal axis extending in a direction that a longitudinal axis of the bridge portion extends such that the horizontally extending rod is mounted between a front portion of the right side panel and a front portion of the left side panel.
