Shared armrest
A shared armrest includes two armrest members which are each configured for supporting a person's arm. The shared armrest is configured so that at least one of the armrest members is displaceable between an undivided condition and a split condition. In the undivided condition the armrest members are substantially together. In the split condition the armrest members diverge relative to each other with respective distal ends of the armrest members spaced apart from each other.
1. A shared armrest includes two armrest members, each of which is configured to support a person's arm, wherein
the shared armrest is configured so that at least one of the armrest members is displaceable between:
an undivided condition wherein the armrest members are together in a side-by-side arrangement, such that longitudinal axes of the armrest members are substantially parallel; and
a split condition wherein the armrest members diverge relative to each other with respective distal ends of the armrest members spaced apart from each other,
the shared armrest includes a hinge body, and the armrest members have a common axis about which the armrest members pivot with respect to the hinge body,
a flap extension is pivotally connected to each armrest member, each flap extension is pivotal between a folded position and an unfolded position, and each flap extension increases a surface area for supporting the person's arm when in the unfolded position, and
the flap extensions are configured to be in either of the folded position and the unfolded position when the corresponding armrest member is in either of the undivided condition and the split condition.
2. The shared armrest of claim 1 , wherein proximal ends of the armrest members are connected to the hinge body.
3. The shared armrest of claim 2 , wherein the hinge body is connectable to a seat or a frame in a hinged manner to provide hinged displacement of the armrest members in a plane transverse to a plane in which the armrest members pivot relative to each other.
4. The shared armrest of claim 1 , wherein the hinge body includes knuckles, and proximal ends of the armrest members include knuckles, which are interleaved with the knuckles of the hinge body to provide a joint assembly in which vertical movement of the armrest members is inhibited.
5. The shared armrest of claim 1 , wherein the armrest members have raised distal ends, which abut each other in the undivided condition to provide a gap between the armrest members.
6. The shared armrest of claim 1 , wherein a range of pivoting of each armrest member is limited.
7. The shared armrest of claim 6 , wherein the armrest members have knuckles at their proximal ends, and the knuckles have arcuate recesses in which a stop formation is received.
8. A row of seats including the shared armrest of claim 1 between adjacent seats.
9. The row of seats of claim 8 , including a row terminating armrest, which is operable to swing inwardly toward a seatback of a row terminating seat.
10. A shared armrest includes two armrest members, each of which is configured to support a person's arm, wherein
the shared armrest is configured so that at least one of the armrest members is displaceable between:
an undivided condition wherein the armrest members are together in a side-by-side arrangement, such that longitudinal axes of the armrest members are substantially parallel; and
a split condition wherein the armrest members diverge relative to each other with respective distal ends of the armrest members spaced apart from each other,
the shared armrest includes a hinge body, and the armrest members pivot with respect to the hinge body,
a flap extension is pivotally connected to each armrest member, each flap extension is pivotal between a folded position and an unfolded position, and each flap extension increases a surface area for supporting the person's arm when in the unfolded position,
each flap extension pivots about an axis that extends in a longitudinal direction of a corresponding one of the armrest members, and
the flap extensions are configured to be in either of the folded position and the unfolded position when the corresponding armrest member is in either of the undivided condition and the split condition.
11. The shared armrest of claim 10 , wherein proximal ends of the armrest members are connected to the hinge body.
12. The shared armrest of claim 11 , wherein the hinge body is connectable to a seat or a frame in a hinged manner to provide hinged displacement of the armrest members in a plane transverse to a plane in which the armrest members pivot relative to each other.
13. The shared armrest of claim 10 , wherein the hinge body includes knuckles, and proximal ends of the armrest members include knuckles, which are interleaved with the knuckles of the hinge body to provide a joint assembly in which vertical movement of the armrest members is inhibited.
14. The shared armrest of claim 10 , wherein the armrest members have raised distal ends, which abut each other in the undivided condition to provide a gap between the armrest members.
15. The shared armrest of claim 10 , wherein a range of pivoting of each armrest member is limited.
16. The shared armrest of claim 15 , wherein the armrest members have knuckles at their proximal ends, and the knuckles have arcuate recesses in which a stop formation is received.
17. A row of seats including the shared armrest of claim 10 between adjacent seats.
18. The row of seats of claim 17 , including a row terminating armrest, which is operable to swing inwardly toward a seatback of a row terminating seat.
19. A shared armrest includes two armrest members, each of which is configured to support a person's arm, wherein
the shared armrest is configured so that at least one of the armrest members is displaceable between:
an undivided condition wherein the armrest members are together in a side-by-side arrangement, such that longitudinal axes of the armrest members are substantially parallel; and
a split condition wherein the armrest members diverge relative to each other with respective distal ends of the armrest members spaced apart from each other,
proximal ends of the armrest members are connected in a pivotal manner to a hinge body, and
the hinge body includes knuckles, and the proximal ends of the armrest members include knuckles, which are interleaved with the knuckles of the hinge body, to provide a joint assembly in which vertical movement of the armrest members is inhibited.
20. A shared armrest includes two armrest members, each of which is configured to support a person's arm, wherein
the shared armrest is configured so that at least one of the armrest members is displaceable between:
an undivided condition wherein the armrest members are together in a side-by-side arrangement, such that longitudinal axes of the armrest members are substantially parallel; and
a split condition wherein the armrest members diverge relative to each other with respective distal ends of the armrest members spaced apart from each other,
the at least one of the armrest members is pivotally connected to a support structure or to the other armrest member,
a range of pivoting of the at least one of the armrest members is limited, and
the armrest members have knuckles at their proximal ends, and the knuckles have arcuate recesses in which a stop formation is received.
