Abstract

A vehicle seating assembly for a motor vehicle has a lower seat and a seatback extending upwardly from the lower seat. The seatback comprises a forward facing surface, a rearward facing surface, and a headrest mounted on an upper portion of the seatback and received within a central recess disposed on the forward facing surface of the seatback, wherein the seatback further comprises a headrest dovetail mounted on the headrest and a dovetail receiver mounted within the recess having a slot into which the headrest dovetail is received.

First claim

What is claimed is:

1. A vehicle seating assembly for a motor vehicle having a lower seat and a seatback extending upwardly from the lower seat, the seatback comprising a forward facing surface, a rearward facing surface, and a headrest mounted on an upper portion of the seatback and received within a central recess disposed on the forward facing surface of the seatback, wherein the seatback further comprises a headrest dovetail mounted on the headrest and a dovetail receiver mounted within the central recess having a slot into which the headrest dovetail is received.

2. The vehicle seating assembly of claim 1 , wherein the seatback further comprises a headrest cup disposed within and defining the central recess.

3. The vehicle seating assembly of claim 1 , wherein the headrest includes a headrest mechanism comprising an upwardly extending tubular member and a rear mounting base plate to which the headrest dovetail is coupled.

4. The vehicle seating assembly of claim 3 , wherein the upwardly extending tubular member is a U-shaped tubular member pivotably coupled with the rear base mounting plate.

5. The vehicle seating assembly of claim 4 , wherein the U-shaped tubular member is pivotably coupled with the rear mounting base plate via a spring-loaded ratchet mechanism which allows pivoting of the headrest to a plurality of positions in discrete increments.

6. The vehicle seating assembly of claim 1 , wherein the headrest dovetail comprises a rectangular block member having a rear surface and a pair of laterally engaging tabs that extend laterally in both side directions beyond the rectangular block member proximate the rear surface.

7. The vehicle seating assembly of claim 6 , wherein the dovetail receiver has a forward surface and an upper surface, each of the forward surface and the upper surface being provided with an opening to create a cavity having a lateral width on the upper surface that exceeds the lateral width of the forward surface and to thereby form a T-shaped slot exposed on the forward surface and the upper surface of the dovetail receiver having a bottom shoulder, the T-shaped slot being adapted to receive the laterally engaging tabs of the headrest dovetail as the headrest dovetail is slid into the T-shaped slot in the dovetail receiver from above until bottoming out on the bottom shoulder.

8. The vehicle seating assembly of claim 7 , further comprising a headrest cup disposed within the central recess, wherein the headrest cup has an opening adapted to conform to the T-shaped slot, the headrest cup substantially concealing the dovetail receiver.

9. The vehicle seating assembly of claim 8 , wherein a forward facing surface of the T-shaped slot is provided with a recess into which a spring-loaded roller bearing is installed and wherein a rearward facing surface of the headrest dovetail is provided with an indented dimple aligned with the spring-loaded roller bearing when the headrest dovetail assembly is slid into the T-shaped slot in the dovetail receiver from above until bottoming out on the bottom shoulder.

10. The vehicle seating assembly of claim 9 , further comprising a pair of recesses into which a pair of spring-loaded roller bearings is mounted and a pair of aligned indented dimples.

11. The vehicle seating assembly of claim 2 , wherein the headrest cup is formed as a polymeric shell mounted within and on the forward facing surface of the seatback and the headrest is removably mounted within the headrest cup.

12. The vehicle seating assembly of claim 11 , wherein the headrest cup is lined with rubber padding.

13. The vehicle seating assembly of claim 1 , wherein the dovetail receiver is mounted to a forward surface of an upper movable seatback hood module capable of vertical adjustment within a range of about 75 mm between an uppermost position and a lowermost position.

14. A seatback for a motor vehicle comprising a forward facing surface, a headrest disposed on an upper portion of the seatback and received within a central recess formed on the forward facing surface of the seatback, wherein the seatback further comprises a headrest dovetail mounted on the headrest and a dovetail receiver mounted within the central recess having a slot into which the headrest dovetail is received.

15. The seatback of claim 14 , wherein the headrest includes a headrest mechanism comprising a U-shaped tubular member pivotably coupled with a rear mounting base plate to which the headrest dovetail is pivotably coupled and a spring-loaded ratchet mechanism which allows pivoting of the headrest to a plurality of positions in discrete increments.

16. The seatback of claim 14 , wherein the headrest dovetail comprises a rectangular block member having a rear surface and a pair of laterally engaging tabs that extend laterally in both side directions beyond the rectangular block member proximate the rear surface and the dovetail receiver comprises a forward surface and an upper surface, each of the forward surface and the upper surface being provided with an opening to create a cavity having a lateral width on the upper surface that exceeds the lateral width of the forward surface and to thereby form a T-shaped slot exposed on the forward surface and the upper surface of the dovetail receiver having a bottom shoulder, the T-shaped slot being adapted to receive the laterally engaging tabs of the headrest dovetail as the headrest dovetail is slid into the T-shaped slot in the dovetail receiver from above until bottoming out on the bottom shoulder.

17. The seatback of claim 16 , wherein a forward facing surface of the T-shaped slot is provided with a pair of recesses into which a pair of spring-loaded roller bearings are installed and wherein a rearward facing surface of the headrest dovetail is provided with a pair of indented dimples aligned with the spring-loaded roller bearings when the headrest dovetail assembly is slid into the T-shaped slot in the dovetail receiver from above and bottomed out on the bottom shoulder.

18. A vehicle seating assembly for a motor vehicle having a lower seat and a seatback extending upwardly from the lower seat;
the seatback comprising a forward facing surface, a headrest disposed on an upper portion of the seatback and received within a central recess formed on the forward facing surface of the seatback, wherein the seatback further comprises a headrest dovetail mounted on the headrest and a dovetail receiver mounted within the central recess having a T-shaped slot into which the headrest dovetail is received;
wherein the headrest dovetail comprises a rectangular block member having a rear surface and a pair of laterally engaging tabs that extend laterally in both side directions beyond the rectangular block member proximate the rear surface and the dovetail receiver comprises a forward surface and an upper surface, each of the forward surface and the upper surface being provided with an opening to create a cavity having a lateral width on the upper surface that exceeds the lateral width of the forward surface and to thereby form the T-shaped slot exposed on the forward surface and the upper surface of the dovetail receiver having a bottom shoulder, the T-shaped slot being adapted to receive the laterally engaging tabs of the headrest dovetail as the headrest dovetail is slid into the T-shaped slot in the dovetail receiver from above until bottoming out on the bottom shoulder.

19. The vehicle seating assembly of claim 18 , wherein the forward facing surface of the T-shaped slot is provided with a pair of recesses into which a pair
