Abstract

A cover anchor clip comprises a base section having a plate shape extending in one direction, that is formed with through holes into which a foam body enters, and that is configured to be retained in the foam body; and an anchor portion including a pair of extension portions that extend upward from a surface of the base section and that are disposed facing each other, and a pair of anchor claws that are formed at respective leading ends of the pair of extension portions, and that is configured to anchor an anchored member attached to a cover for covering the foam body by sandwiching the anchored member therebetween. The through holes formed at the base section are aligned in the one direction, and plural hole-rows formed by the through holes aligned in the one direction are disposed separated by a spacing in an intersection direction intersecting the one direction. A gate mark that indicates an injection port for resin material during molding is formed at the back face of the base section between adjacent hole-rows. A plate thickness changing portion at which a thickness of the base section changes is formed between the gate mark and the through holes, as viewed from a back face of the base section along a plate thickness direction of the base section.

First claim

What is claimed is:

1 . A cover anchor clip comprising:
abase section having a plate shape extending in one direction, that is formed with through holes into which a foam body enters, and that is configured to be retained in the foam body; and an anchor portion including:
a pair of extension portions that extend upward from a surface of the base section and that are disposed facing each other, and
a pair of anchor claws that are formed at respective leading ends of the pair of extension portions, and that are configured to anchor an anchored member attached to a cover for covering the foam body by sandwiching the anchored member therebetween,
wherein the through holes formed at the base section are aligned in the one direction, and a plurality of hole-rows formed by the through holes aligned in the one direction are separated by a spacing in an intersection direction intersecting the one direction, a gate mark that indicates an injection port for resin material during molding being formed at the back face of the base section between adjacent hole-rows of the hole-rows, and a plate thickness changing portion at which a thickness of the base section changes being formed between the gate mark and the through holes, as viewed from a back face of the base section along a plate thickness direction of the base section.

2 . The cover anchor clip of claim 1 , wherein the plate thickness changing portion is shaped as a curved line as viewed along the plate thickness direction.

3 . The cover anchor clip of claim 1 , wherein the plate thickness changing portion is shaped by a straight line portion and an angular portion as viewed along the plate thickness direction.

4 . The cover anchor clip of claim 1 , wherein the plate thickness changing portion extends in the intersection direction.

5 . The cover anchor clip of claim 1 , wherein the plate thickness changing portion is formed at one side in the one direction and at another side in the one direction, with the gate mark lying therebetween, and the plate thickness of the base section between two plate thickness changing portions is thicker than that of other portions of the base section.
