Seat, particularly for public transportation

A seat (1), particularly for public transportation, having a carrying frame (2) and a support unit (8) connected thereto, said support unit having a base frame (6) as well as an elastic cover (10) held thereon and made of a knitted fabric (11) as an unsupported structure, and said cover (10) forming a support surface (9) having a seat region (13) and a back region (12), wherein said cover (10) is configured to be continuous between the seat region (13) and the back region (12) and the support surface (9) of the cover (10) has a plurality of zones (33 to 38) located consecutively in the longitudinal direction of said cover, of which at least one zone (34) has a greater elastic deformability relative to the other zones (33, 35, 36, 37, 38), wherein zone (34) having the greatest elastic deformability is formed between the seat region (13) and the back region (12), and wherein in a strip-shaped edge section (42) of the zone (33) of the back region (12) is disposed in each case in the longitudinal edge region (41) of the knitted fabric (11) on both sides of the zone (34) having the greatest elastic deformability.
