Abstract

A passenger seat includes a spreader with one or more open slot. The slot may be positioned on a lateral side of the spreader and may receive a portion of a seat base of the passenger seat within the slot. In some aspects, the slot may be elongated, and an insertion opening for the slot is provided in a top side of the spreader.

First claim

That which is claimed is:

1. A spreader for a passenger seat, the spreader comprising:
a forward end;
an aft end opposite from the forward end;
a top side;
a bottom side opposite from the top side;
a first side extending from the forward end to the aft end;
a second side opposite from the first side and extending from the forward end to the aft end; and
a slot on the first side and configured to receive a portion of a base assembly within the slot, wherein the slot is elongated, and wherein the top side defines an insertion opening providing access to the slot,
wherein the slot is a first slot and the insertion opening is a first insertion opening, and wherein the spreader further comprises a second slot on the first side, wherein the second slot is elongated, and wherein the top side defines a second insertion opening providing access to the second slot.

2. The spreader of claim 1 , wherein the second insertion opening is between the first insertion opening and the aft end.

3. The spreader of claim 1 , wherein at least one characteristic of the second slot is different from the first slot.

4. The spreader of claim 1 , wherein the at least one characteristic comprises at least one of a height of the insertion opening, a length of the insertion opening, a length of the second slot, an angle of the second slot relative to a horizontal axis, or a shape of the second slot.

5. The spreader of claim 1 , wherein the spreader further comprises a second third slot on the second side, wherein the third slot is elongated, and wherein the top side defines a third insertion opening providing access to the third slot.

6. The spreader of claim 5 , wherein the first insertion opening is aligned with the third insertion opening between the forward end and the aft end.

7. The spreader of claim 1 , wherein the first insertion opening comprises a forward edge and an aft edge, and wherein the forward edge and the aft edge are coplanar.

8. The spreader of claim 1 , wherein the first insertion opening comprises a forward edge and an aft edge, and wherein the forward edge and the aft edge are non-coplanar.

9. The spreader of claim 8 , wherein the aft edge is vertically above the forward edge and the insertion opening is angled upwards in a forward and aft direction.

10. The spreader of claim 1 , wherein the first insertion opening defines a greatest width of the first slot.

11. The spreader of claim 1 , wherein the first slot is elongated towards the forward end from the insertion opening.

12. A passenger seat comprising:
the spreader of claim 1 ; and
a base assembly comprising a roller, wherein the roller is positioned in the first slot via the first insertion opening or in the second slot via the second insertion opening.

13. The passenger seat of claim 12 , further comprising a seatback, wherein the seatback is fixed relative to the base assembly.

14. The passenger seat of claim 12 , further comprising an anchor configured to engage the base assembly when the roller is positioned in the first slot or the second slot.

15. A spreader for a passenger seat, the spreader comprising:
a forward end;
an aft end opposite from the forward end;
a top side;
a bottom side opposite from the top side;
a side extending from the forward end to the aft end; and
a slot on the side and configured to receive a portion of a base assembly within the slot,
wherein the slot comprises an insertion opening in the top side, and wherein the slot is elongated towards the forward end from the insertion opening,
wherein the slot is a first slot and the insertion opening is a first insertion opening, and wherein the spreader further comprises a second slot on the side, wherein the second slot is elongated, and wherein the top side defines a second insertion opening providing access to the second slot.

16. The spreader of claim 15 , wherein the first insertion opening comprises a forward edge and an aft edge, and wherein the aft edge is vertically above the forward edge.

17. A spreader for a passenger seat, the spreader comprising:
a forward end;
an aft end opposite from the forward end;
a top side;
a bottom side opposite from the top side;
a first side extending from the forward end to the aft end;
a second side opposite from the first side and extending from the forward end to the aft end; and
a slot on the first side and configured to receive a portion of a base assembly within the slot, wherein the slot is elongated, and wherein the top side defines an insertion opening providing access to the slot,
wherein the insertion opening comprises a forward edge and an aft edge, and wherein the forward edge and the aft edge are coplanar.
