Abstract

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.

First claim

What is claimed is:

1 . A seat assembly comprising:
a seat base structure; a seat cushion supported by the seat base structure; and a lateral outboard seat lip positioned relative to the seat cushion so as to assist a passenger during seat entry and exit.

2 . The seat assembly according to claim 1 , wherein the lateral outboard seat lip is 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.

3 . 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.

4 . The seat assembly according to claim 3 , 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.

5 . The seat assembly according to claim 3 , wherein the lateral inboard seat lip is attached relative to the seat cushion for manual movements between an extended position wherein the inboard seat lip extends outwardly thereby increasing effective surface area of the seat cushion and a deflected position wherein the inboard seat lip extends upwardly or downwardly relative to the seat cushion so as to thereby decrease the effective surface area of the seat cushion.

6 . The seat assembly according to claim 3 , wherein each of the inboard and outboard seat lips is rigid.

7 . The seat assembly according to claim 3 , wherein each of the inboard and outboard seat lips is attached to the seat base structure.

8 . The seat assembly according to claim 3 , wherein each of the inboard and outboard seat lips is integral with the seat cushion.

9 . 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.

10 . The seat assembly according to claim 9 , wherein the seat back comprises a head rest.

11 . A vehicle which comprises the seat assembly according to claim 1 .

12 . A seating arrangement which comprises a set of seat assemblies according to claim 1 positioned in side-by-side relationship.

13 . The seating arrangement according to claim 12 , wherein the lateral outboard seat lip of each seat assembly is 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.

14 . The seating arrangement according to claim 12 , which wherein each seat assembly further comprises a lateral inboard seat lip positioned relative to the seat cushion opposite of the outboard seat lip.

15 . The seating arrangement according to claim 14 , 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.

16 . The seating arrangement according to claim 14 , wherein the lateral inboard seat lip is attached relative to the seat cushion for manual movements between an extended position wherein the inboard seat lip extends outwardly thereby increasing effective surface area of the seat cushion and a deflected position wherein the inboard seat lip extends upwardly or downwardly relative to the seat cushion so as to thereby decrease the effective surface area of the seat cushion.

17 . The seating arrangement according to claim 14 , wherein each of the inboard and outboard seat lips is rigid.

18 . The seating arrangement according to claim 12 , which further comprises a fixed-position common inboard seat lip conjointly extending between each of the seat assemblies.

19 . The seating arrangement according to claim 18 , wherein the common inboard seat lip is elevated relative to top seating surfaces of the seat cushions of the seat assemblies.

20 . The seating arrangement according to claim 19 , wherein the common inboard seat lip is inclined upwardly from a front end thereof toward an aft end thereof.

21 . A vehicle which comprises the seating arrangement according to claim 12 .
