Blow-molded headrest armature assembly

Claim 2

An armature assembly for use in a motor vehicle headrest comprising two substantially straight support posts joined to a preformed hollow elongated armature having angular indentations formed therein for receiving one end of each support post and to permit retention of the support posts in a fixed position relative to each other.

Claim 3

The armature assembly of claim 1 in which the support posts are solid steel.

Claim 4

The armature assembly of claim 1 in which the support posts are parallel to each other.

Claim 5

The armature assembly of claim 1 in which the armature is formed to provide a shroud about the end of each support post.

Claim 6

A motor vehicle headrest comprising the armature assembly of claim 1, a suitable amount of foam disposed around the armature, and a cover.

Claim 7

The armature assembly of claim 1 in which the support posts include a curved portion adjacent the armature.

Claim 8

The armature assembly of claim 1 in which the support posts have multiple notches to permit adjustment of the height of the headrest with respect to a motor vehicle seat back.

Claim 9

The armature assembly of claim 1 in which one end of each support post is provided with a substantially flattened surface adjacent the armature.

Claim 10

The armature assembly of claim 1 in which the armature is made of blow molded plastic.

Claim 11

The armature assembly of claim 1 in which each support post has a formed upper end, and the armature is provided with at least two attachment ports, each having a surface shaped to contact flush to at least a portion of the formed upper end of each support post.

Claim 12

The armature assembly of claim 10 in which the armature is provided with front and back angular indentations formed therein at each attachment port.

Claim 13

The armature assembly of claim 1 in which the support posts are joined to the armature by one or more rivets.

Claim 14

The armature assembly of claim 1 in which each support post is joined to the armature by at least two rivets.

Claim 15

An armature assembly for use in a motor vehicle headrest comprising: two substantially straight support posts, wherein a formed upper end of each support post has a substantially flattened surface adjacent the armature; and, a blow molded hollow elongated plastic armature, preformed with attachment ports comprising paired angular indentations formed therein each said attachment port being adapted to receive one end of one of said support posts to permit retention of the support posts in a fixed position relative to each other and, a fastener extending through each of said support posts and said attachment ports and firmly securing said support posts to said attachment ports.

Claim 16

An armature assembly for use in a motor vehicle headrest comprising: two substantially straight support posts, wherein a formed upper end of each support post has a substantially flattened surface adjacent the armature; and, a blow molded hollow elongated plastic armature, preformed with attachment ports comprising paired angular indentations formed therein each said attachment port being adapted to receive one end of one of said support posts to permit retention of the support posts in a fixed position relative to each other and, a fastener extending through each of said support posts and said attachment ports and firmly securing said support posts to said attachment ports.

Claim 17

An armature assembly for a headrest comprising two steel support posts joined to a plastic armature having one or more attachment ports, wherein: each of said support posts has a formed upper end; said armature, comprising essentially a hollow elongated box, forms a shroud about the formed upper end of each said support post; said armature further includes at least one angular indentation formed therein at each attachment port with a surface formed to mate with a corresponding surface of the formed upper end of a corresponding one of said support posts; each attachment port is shaped to receive the formed upper end of the corresponding one of said support posts such that the support posts are retained in a fixed and essentially parallel position relative to each other; and, each of said support posts, being essentially straight along most of its length, has a curved portion near said formed upper end adjacent the armature.

Claim 18

An armature assembly for a headrest comprising two steel support posts joined to a plastic armature having one or more attachment ports, wherein: each of said support posts has a formed upper end; said armature, comprising essentially a hollow elongated box, forms a shroud about the formed upper end of each said support post; said armature further includes at least one angular indentation formed therein at each attachment port with a surface formed to mate with a corresponding surface of the formed upper end of a corresponding one of said support posts; each attachment port is shaped to receive the formed upper end of the corresponding one of said support posts such that the support posts are retained in a fixed and essentially parallel position relative to each other; and, each of said support posts, being essentially straight along most of its length, has a curved portion near said formed upper end adjacent the armature.

Claim 19

A motor vehicle headrest comprising the armature assembly of claim 15, a suitable amount of foam disposed around the armature, and a cover.
