Abstract

A seat headrest is provided that includes a mounting plate for attachment to a seat back of the seat. First and second side wings are mounted on opposite ends of the mounting plate. The side wings are mounted for pivotal movement between a retracted position against the mounting plate and a deployed position extending outwardly away from the mounting plate, and for sliding movement between the retracted position against the mounting plate and a further deployed position extending outwardly away from the mounting plate.

First claim

We claim:

1. A seat headrest, comprising:
(a) a mounting plate for attachment to an upper end of a seat back of the seat;
(b) first and second slide assemblies mounted in spaced-apart relation on the mounting plate;
(c) first and second head-supporting side wings mounted on respective ones of the first and second slide assemblies for supporting a seat occupant's head against one of the first and second head-supporting side wings and for sliding movement between a relatively narrow spaced-apart position and a relatively wide spaced-apart position, the first and second slide assemblies mounted on the mounting plate at an oblique angle whereby the first and second head-supporting side wings lower as they move apart and raise as they move together;
(d) first and second hinges on which the first and second head-supporting side wings are respectively mounted for pivotal movement between a retracted position against the mounting plate and a deployed head-supporting position extending outwardly away from the mounting plate independent of the sliding movement of the first and second head-supporting side wings; and
(e) first and second support arms positioned on the mounting plate and supporting the respective first and second head-supporting side wings in a pre-determined angular head-supporting adjusted position and in a pre-determined spaced-apart position relative to the first and second slide assemblies.

2. The seat headrest according to claim 1 , and including first and second roller assemblies carried by respective first and second head-supporting side wings and adapted to permit low-friction sliding movement of the first and second head-supporting side wings on the respective first and second slides.

3. The headrest according to claim 2 , and including first and second slide hinge arms mounted for hinged pivoting movement relative to the respective first and second support arms.

4. The headrest according to claim 1 , wherein the first and second side wings each comprise a rigid plate.

5. The headrest according to claim 1 , including first and second flexible membranes stretched between respective first and second side wings and a central portion of the mounting plate between the first and second side wings.

6. The headrest according to claim 1 , including first and second curved, padded tongues attached to the respective side wings and a central portion of the mounting plate between the first and second side wings.

7. The headrest according to claim 1 , wherein the first and second support arms are positioned on the mounting plate and extend outwardly and engage the respective side wings at an oblique angle that varies as the first and second side wings slide along the respective slide assemblies.

8. The headrest according to claim 1 , and including first and second curved, padded tongues attached to the respective side wings and a central portion of the mounting plate between the first and second side wings, the first and second curved, padded tongues extending along an inward-facing surface of the respective first and second side wings and wrapping around respective distal ends of the respective first and second side wings.

9. A seat headrest, comprising:
(a) a mounting plate for attachment to an upper end of a seat back of the seat;
(b) first and second slide assemblies mounted in spaced-apart relation on the mounting plate;
(c) first and second head-supporting side wings mounted on respective ones of the first and second slide assemblies for supporting a seat occupant's head against one of the first and second head-supporting side wings and for sliding movement between a relatively narrow spaced-apart position and a relatively wide spaced-apart position;
(d) first and second roller assemblies carried by the respective first and second head-supporting side wings and adapted to permit low-friction sliding movement of the first and second head-supporting side wings on the respective first and second slide assemblies;
(e) first and second hinges on which the first and second head-supporting side wings are respectively mounted for pivotal movement between a retracted position against the mounting plate and a deployed head-supporting position extending outwardly away from the mounting plate independent of the sliding movement of the first and second head-supporting side wings;
(f) first and second support arms positioned on the mounting plate and supporting the respective first and second head-supporting side wings in a pre-determined angular head-supporting adjusted position and in a pre-determined spaced-apart position relative to the first and second slide assemblies; and
(g) first and second slide hinge arms mounted for hinged pivoting movement relative to the respective first and second support anus.

10. The headrest according to claim 9 , wherein the first and second slide assemblies are mounted on the mounting plate at an oblique angle whereby the side wings lower as they move apart and raise as they move together.

11. The headrest according to claim 9 , wherein the first and second side wings each comprise a rigid plate.

12. The headrest according to claim 9 , including first and second flexible membranes stretched between respective first and second side wings and a central portion of the mounting plate between the first and second side wings.

13. The headrest according to claim 9 , including first and second curved, padded tongues attached to the respective side wings and a central portion of the mounting plate between the first and second side wings.

14. The headrest according to claim 9 , wherein the first and second support arms are positioned on the mounting plate and extend outwardly and engage the respective side wings at an oblique angle that varies as the first and second side wings slide along the respective slide assemblies.

15. The headrest according to claim 9 , and including first and second curved, padded tongues attached to the respective side wings and a central portion of the mounting plate between the first and second side wings, the first and second curved, padded tongues extending along an inward-facing surface of the respective first and second side wings and wrapping around respective distal ends of the respective first and second side wings.
