Passenger transport seats with lateral seat lips
Seat assemblies are provided which include a seat base structure, a seat cushion supported by the seat base structure and at least a lateral outboard seat lip positioned relative to the seat cushion so as to assist a passenger during seat entry and exit. The lateral outboard seat lip is preferably attached relative to the seat cushion for manual movements between an extended position wherein the outboard seat lip extends outwardly thereby increasing effective surface area of the seat cushion and a deflected position wherein the outboard seat lip extends upwardly or downwardly relative to the seat cushion so as to thereby decrease the effective surface area of the seat cushion.
1. A seat assembly comprising:
a seat base structure;
a seat cushion supported by the seat base structure which defines a top seating surface; and
a lateral outboard seat lip positioned relative to the seat cushion so as to assist a passenger during seat entry and exit, wherein
the lateral outboard seat lip is attached relative to the seat cushion for manual movements between (i) an outboard extended position wherein the outboard seat lip extends essentially horizontally outwardly of the seat cushion to thereby provide an essentially horizontal extension of the seat cushion to increase an effective surface area of the top seating surface, (ii) an outboard upwardly inclined deflected position wherein the outboard seat lip extends upwardly and outwardly relative to the top seating surface of the seat cushion to provide a lateral thigh support for an occupant seated on the top seating surface of the seat cushion, and (iii) an outboard downwardly inclined deflected position wherein the outboard seat lip extends downwardly and outwardly relative to the top seating surface of the seat cushion so as to thereby decrease the effective surface area of the top seating surface and allow an occupant to more easily be seated on the top seating surface of the seat cushion.
2. The seat assembly according to claim 1 , which further comprises a lateral inboard seat lip positioned relative to the seat cushion opposite of the outboard seat lip.
3. The seat assembly according to claim 2 , wherein the inboard seat lip is in a fixed-position so as to be upwardly deflected relative to the top seating surface of the seat cushion.
4. The seat assembly according to claim 2 , wherein the lateral inboard seat lip is attached relative to the seat cushion for manual movements between (i) an inboard extended position wherein the inboard seat lip extends essentially horizontally outwardly from the top seat surface of the seat cushion thereby increasing the effective surface area of the top seat surface of the seat cushion, (ii) an inboard upwardly inclined deflected position wherein the inboard seat lip extends upwardly and outwardly relative to the top seat surface of the seat cushion, and (iii) an inboard downwardly inclined deflected position wherein the inboard seat lip extends downwardly and outwardly relative to the top seat surface of the seat cushion.
5. The seat assembly according to claim 2 , wherein each of the inboard and outboard seat lips is attached to the seat base structure.
6. The seat assembly according to claim 2 , wherein each of the inboard and outboard seat lips is integral with the seat cushion.
7. The seat assembly according to claim 1 , further comprising a seat back connected to the seat base structure and upwardly extending from the seat cushion.
8. The seat assembly according to claim 7 , wherein the seat back comprises a head rest.
9. A vehicle which comprises the seat assembly according to claim 1 .
10. A seating arrangement which comprises a set of seat assemblies according to claim 1 positioned in side-by-side relationship.
11. The seating arrangement according to claim 10 , wherein the lateral outboard seat lip of each seat assembly is attached relative to the seat cushion for manual movements between (i) the outboard extended position, (ii) the outboard upwardly inclined deflected position, and (iii) the outboard downwardly inclined deflected position.
12. The seating arrangement according to claim 10 , which wherein each seat assembly further comprises a lateral inboard seat lip positioned relative to the seat cushion opposite of the outboard seat lip.
13. The seating arrangement according to claim 12 , wherein the inboard seat lip is in a fixed-position so as to be upwardly deflected relative to a top seating surface of the seat cushion.
14. The seating arrangement according to claim 12 , wherein the lateral inboard seat lip is attached relative to the seat cushion for manual movements between (i) an inboard extended position wherein the inboard seat lip extends essentially horizontally outwardly thereby increasing the effective surface area of the top seat surface of the seat cushion, (ii) an inboard upwardly inclined deflected position wherein the inboard seat lip extends upwardly and outwardly relative to the top seat surface of the seat cushion, and (iii) an inboard downwardly inclined deflected position wherein the inboard seat lip extends downwardly and outwardly relative to the top seat surface of the seat cushion.
15. The seating arrangement according to claim 10 , which further comprises a fixed-position common inboard seat lip conjointly extending between each of the seat assemblies.
16. The seating arrangement according to claim 15 , wherein the common inboard seat lip is elevated relative to top seating surfaces of the seat cushions of the seat assemblies.
17. The seating arrangement according to claim 16 , wherein the common inboard seat lip is inclined upwardly from a front end thereof toward an aft end thereof.
18. A vehicle which comprises the seating arrangement according to claim 10 .
