Abstract

An adjustable headrest assembly for an aircraft seat with secondary flaps is disclosed. The adjustable headrest assembly may include a base structure configured to attach to a headrest area of an aircraft seat. The base structure may include a base frame with u-shaped brackets on both an upper and a lower side. The base structure may also include two slide guides configured to retain sliding members, with an upper slide guide coupling into the u-shaped brackets on the upper side and a lower slide guide coupling into the u-shaped brackets on the lower side. The sliding members may include a first sliding member and a second sliding member, configured to slide horizontally outwards. The assembly may further include primary flaps, each rotatably coupled to opposing sides of the base structure, and secondary flaps, each rotatably coupled to the primary flaps.

First claim

What is claimed:

1 . An adjustable headrest assembly for an aircraft seat, the adjustable headrest assembly comprising:
a base structure configured to attach to a headrest area of an aircraft seat, wherein the base structure comprises:
a base frame comprising u-shaped brackets on an upper side of the base frame and u-shaped brackets on a lower side of the base frame; and
two slide guides configured to retain sliding members,
wherein the two slide guides comprise:
an upper slide guide configured to couple into the u-shaped brackets on the upper side of the base frame; and

a lower slide guide configured to couple into the u-shaped brackets on the lower side of the base frame;
wherein the sliding members comprise a first sliding member and a second sliding member, wherein the first sliding member is configured to simultaneously be retained within a first side of the upper slide guide and the lower slide guide, wherein the second sliding member is configured to simultaneously be retained within a second side of the upper slide guide and the lower slide guide, wherein the first side is opposite relative to the second side; wherein the sliding members are configured to slide horizontally outwards;
primary flaps comprising a first primary flap and a second primary flap, the primary flaps rotatably coupled to opposing sides of the base structure via a primary set of friction hinges configured to rotate around a primary rotation axis; and secondary flaps comprising:
a first secondary flap rotatably coupled to the first primary flap; and
a second secondary flap rotatably coupled to the second primary flap,
wherein the secondary flaps are coupled via a secondary set of friction hinges configured to rotate around a secondary rotation axis that is perpendicular to the primary rotation axis.

2 . The adjustable headrest assembly of claim 1 , wherein the adjustable headrest assembly is configured to support a user's shoulders when the secondary flaps are in a folded down position.

3 . The adjustable headrest assembly of claim 1 , when in a folded stowed position, a shape of secondary flap cushions of the secondary flaps is equal to, overlapping with, and aligned with a shape of primary flap cushions of the primary flaps.

4 . The adjustable headrest assembly of claim 1 , wherein a base structure cushion coupled to the base frame is twice a thickness of primary flap cushions and secondary flap cushions coupled to the primary flaps and secondary flaps, respectively.

5 . The adjustable headrest assembly of claim 4 , wherein the adjustable headrest assembly comprises dress cover fabric between primary flaps cushions covers of the primary flaps and a base structure cushion cover of the base structure cushion.

6 . The adjustable headrest assembly of claim 1 , wherein the primary flaps are rotatable between 0 to at least 90 degrees relative to the base structure.

7 . The adjustable headrest assembly of claim 1 , wherein the secondary flaps are rotatable between 0 to at least 180 degrees relative to the primary flaps.

8 . The adjustable headrest assembly of claim 1 , wherein the base structure is configured to enable a horizontal movement of the first primary flap and the second primary flap by at least 3.35 inches.

9 . The adjustable headrest assembly of claim 1 , wherein the secondary flaps are configured to provide shoulder support to users having a height of less than 5 foot 9 inches when rotated to a second position.

10 . The adjustable headrest assembly of claim 1 , wherein the adjustable headrest assembly further comprises stops configured to stop a horizontal movement of the first sliding member and the second sliding member by engaging one or more slot ends of slots of the first sliding member and the second sliding member.

11 . An aircraft seat comprising:
a seat frame; and an adjustable headrest assembly coupled to the seat frame and comprising:
a base structure configured to attach to a headrest area of an aircraft seat, wherein the base structure comprises:
a base frame comprising u-shaped brackets on an upper side of the base frame and u-shaped brackets on a lower side of the base frame; and
two slide guides configured to retain sliding members, wherein the two slide guides comprise:
an upper slide guide configured to couple into the u-shaped brackets on the upper side of the base frame; and
a lower slide guide configured to couple into the u-shaped brackets on the lower side of the base frame;

wherein the sliding members comprise a first sliding member and a second sliding member, wherein the first sliding member configured to simultaneously be retained within a first side of the upper slide guide and the lower slide guide, wherein the second sliding member is configured to simultaneously be retained within a second side of the upper slide guide and the lower slide guide, wherein the first side is opposite relative to the second side; wherein the sliding members are configured to slide horizontally outwards;

primary flaps comprising a first primary flap and a second primary flap, the primary flaps rotatably coupled to opposing sides of the base structure via a primary set of friction hinges configured to rotate around a primary rotation axis; and
secondary flaps comprising:
a first secondary flap rotatably coupled to the first primary flap; and
a second secondary flap rotatably coupled to the second primary flap,
wherein the secondary flaps are coupled via a secondary set of friction hinges configured to rotate around a secondary rotation axis that is perpendicular to the primary rotation axis.

12 . The aircraft seat of claim 11 , wherein the adjustable headrest assembly is configured to support a user's shoulders when the secondary flaps are in an folded down position.

13 . The aircraft seat of claim 11 , when in a folded stowed position, a shape of secondary flap cushions of the secondary flaps is equal to, overlapping with, and aligned with a shape of primary flap cushions of the primary flaps.

14 . The aircraft seat of claim 11 , wherein a base structure cushion coupled to base frame is twice a thickness of primary flap cushions and secondary flap cushions coupled to the primary flaps and secondary flaps, respectively.

15 . The aircraft seat of claim 14 , wherein the adjustable headrest assembly comprises dress cover fabric between primary flaps cushions covers of the primary flaps and a base structure cushion cover of the base structure cushion.

16 . The aircraft seat of claim 11 , wherein the primary flaps are rotatable between 0 to at least 90 degrees relative to the base structure.

17 . The aircraft seat of claim 11 , wherein the secondary flaps are rotatable between 0 to at least 180 degrees relative to the primary flaps.

18 . The aircraft seat of claim 11 , wherein the base structure is configured to enable a horizontal movement of the first primary flap and the second primary flap by at least 3.35 inches.

19 . The aircraft seat of claim 11 , wherein the secondary flaps are configured to provide shoulder support to users having a height of less than 5 foot 9 inches when rotated to a second position.
