Abstract

This disclosure includes armrests having one or more laminates and methods and kits for making the same. Some armrests include an elongated beam extending between a first end and a second end, the elongated beam having one or more laminates configured to be disposed along the elongated beam, each including a plurality of fibers dispersed within a matrix material, and a reinforcing structure having a plurality of ribs, the reinforcing structure configured to be coupled to the one or more laminates, where the first end of the elongated beam is configured to be pivotally coupled to a mount. In some armrests, the one or more laminates are configured to be disposed along the elongated beam such that the one or more laminates define a channel and/or an arch extending between the first and second ends.

First claim

1 - 2 . (canceled)

3 . An armrest comprising:
an elongated beam extending between a first end and a second end, the elongated beam including:
one or more laminates, each comprising a plurality of fibers dispersed within a matrix material, the one or more laminates configured to be disposed along the elongated beam such that the one or more laminates define a channel having a bottom portion and opposing side portions that each extend away from the bottom portion, the channel extending between the first and second ends; and
a reinforcing structure including a plurality of ribs, the reinforcing structure configured to be coupled to the one or more laminates such that the plurality of ribs extend into the channel;
wherein the first end of the elongated beam is configured to be pivotally coupled to a mount.

4 . The armrest of claim 3 , wherein the one or more laminates define an arch extending between the first and second ends.

5 . The armrest of claim 3 , wherein a depth of the channel decreases from the first end to the second end.

6 . The armrest of claim 3 , wherein the one or more laminates extend along a majority of the length of the elongated beam.

7 . The armrest of claim 3 , wherein the one or more laminates define at least a portion of an outermost surface of the elongated beam.

8 . The armrest of claim 3 , wherein:
the one or more laminates define one or more openings or slots; and the reinforcing structure is disposed through the one or more openings or slots.

9 . The armrest of claim 3 , wherein the elongated beam includes a cover configured to be coupled to the reinforcing structure.

10 . The armrest of claim 9 , wherein the cover is configured to be coupled to the reinforcing structure via interlocking engagement of the cover and the reinforcing structure.

11 . The armrest of claim 9 , wherein the cover is unitary with at least a portion of the reinforcing structure.

12 . The armrest of claim 9 , wherein the cover is configured to extend around at least a portion of the one or more laminates at the second end.

13 . The armrest of claim 3 , wherein:
the first end of the elongated beam defines one or more openings or slots configured to receive one or more fasteners to pivotally couple the elongated beam to the mount; and at least one of the one or more openings or slots is defined through the one or more laminates and the reinforcing structure.

14 . The armrest of claim 3 , wherein:
the first end of the elongated beam is configured to be pivotally coupled to the mount such that the elongated beam is movable relative to the mount between a stowed position and a deployed position in which the elongated beam extends further from the mount in a horizontal direction than when in the stowed position; and the armrest comprises one or more support elements configured to be coupled between the mount and the elongated beam such that the one or more support elements physically limit movement of the elongated beam beyond the deployed position.

15 . The armrest of claim 3 , comprising one or more elbow rests, each configured to be movably coupled to the elongated beam such that the elbow rest is movable relative to the elongated beam between a stowed position and a deployed position in which the elbow rest extends further from the elongated beam in a horizontal direction than when in the stowed position.

16 . The armrest of claim 15 , wherein, for each of the one or more elbow rests, a portion of the elbow rest that is disposed outside of the elongated beam when the elbow rest is in the deployed position is disposed within the elongated beam when the elbow rest is in the stowed position.

17 . The armrest of claim 3 , comprising a divider configured to be movably coupled to the elongated beam such that the divider is movable relative to the elongated beam between a stowed position and a deployed position in which the divider extends further from the elongated beam in a vertical direction than when in the stowed position.

18 . The armrest of claim 3 , wherein at least a portion of the reinforcing structure and the matrix material of at least one of the one or more laminates comprise the same material.

19 . (canceled)

20 . A method for forming an armrest, the method comprising:
overmolding a plastic material onto one or more laminates to form an elongated beam extending between a first end and a second end, each of the one or more laminates including a plurality of fibers dispersed within a matrix material; wherein the overmolding is performed such that:
the one or more laminates define an arched channel having a bottom portion and opposing side portions that each extend away from the bottom portion, the channel extending between the first and second ends; and
the plastic material defines a reinforcing structure including a plurality of ribs, each extending into the arched channel.
