Abstract

A vehicle seat, in particular a passenger seat for a bus, includes a seat member with a seat upholstery carrier and seat upholstery, which is rigidly arranged on the seat upholstery carrier; the vehicle seat also includes a backrest with a back upholstery carrier and back upholstery, which is rigidly arranged on the back upholstery carrier; and a support structure for receiving forces which act on the vehicle seat. The support structure is constructed as a rigid carrier frame arranged at the peripheral side outside the seat member and the backrest and which is connected to the seat upholstery carrier and the back upholstery carrier. The carrier frame has carrier rails which are arranged in pairs and which extend along opposing lateral edges of the seat member and the backrest.
