Abstract
The door threshold for a railway vehicle is intended to partially fill the gap between the vehicle and a platform. It comprises a support (22) which can be connected to the structure (16) of the railway vehicle and a strip (24) which is retained by the support (22). The strip (24) can be displaced between a normal position, in which it projects relative to the support (22), and a position retracted in the support (22). It comprises means (30A, 30B) for clamping the strip against at least a clamping surface (30A, 30B) of the support in order to produce friction of a specific value between the strip (24) and the support (22) counter to the displacement of the strip (24) relative to the support (22) in the plane of the or each clamping surface (30A, 30B).
