Abstract (en)
A coupling for a rail vehicle comprises a coupler shank (2) for attaching the coupling to a rail vehicle, a coupler head (1) pivotably connected to a free end of the coupler shank so as to rotate about a primary axis (6) between an operational position and a non-operational position, a pivoting mechanism configured to rotate the coupler head (1) about the primary axis (6) from the coupler head's operational position toward the coupler head's non-operational position, and a locking member (8) configured to block rotation of the coupler head (1) about the primary axis (6) when the coupler head (1) is in the operational position. When the pivoting mechanism is actuated so as to rotate the coupler head (1) from the coupler head's operational position to the coupler head's non-operational position, the pivoting mechanism moves from an operational state to an interim state in a first period and from the interim state to a non-operational state in a second period, wherein the pivoting mechanism is configured to release the locking member (8) during the first period and to rotate the coupler head (1) into the non-operational position during the second period.
