- a seat pan (21) havingseat and backrest portions (22,
23) having inward and outward facing sides,a flange (24) directed to extend at a first angle (A) toward said inward facing side and terminating in a contoured edge (26) to provide said seat pan inward facing side with a concave seat and backrest cushion receiving portion,said flange having an inner surface (25) adjacent said contoured edge, andan edge finishing means (63, 163, 263,
363) on said contoured edge of said seat pan,an inner support ring (31) on said inward facing side of said seat pan havinga periphery (30) matching the contour of said contoured edge,a main portion (32) extending inwardly from said periphery, coextensively with and in spaced parallel relation to said inner surface of said flange,a lock rim portion (33) flaring outwardly at a second angle (B) toward said contoured edge,an interior surface (36)an outer surface (34) in facing relation to said seat pan inner surface (25),a seat front peripheral portion (37),a seat backrest top peripheral portion 38, andseat side peripheral portions (39,
41);
a mounting means (71) securing said inner support ring on said inward facing side of said seat pan;

Abstract
A seat assembly for use on a vehicle which comprises a seat pan having seat and backrest portions and a contoured edge. An inner support ring is provided that has a periphery to match the contoured edge, and an interior surface and an outer surface. Seat and backrest cushions are supported by the seat pan and have an outer margin secured to the interior surface of the support ring. A channel shaped finishing strip is mounted on the contoured edge. An upholstery covers the cushion and has a selvage edge that extends beyond the cushion to lay between the outer surface of the support ring and the contoured edge of the seat pan. A mounted means secures the support ring to the seat pan to lock both the selvage edge and the channel shaped finishing strip in place between the support ring and the contoured edge.
