1. A device for actuating locks on a door of a vehicle, the device comprising:

  • a rotary latch arranged in a lock on a door and spring-loaded into an open position, wherein the rotary latch, when the door is closed, receives a stationary lock member of the lock and is rotated into at least one defined locked position, wherein the rotary latch has at least one detent;

    a catch pivotably and stationarily supported in the lock, wherein the catch, upon rotation of the rotary latch, drops into the at least one detent of the rotary latch and defines a blocking position of the catch for securing the locked position of the rotary latch;

    a catch spring having a spring force and forcing the catch into the blocking position;

    an actuation for lifting the catch from the blocking position into a release position in which release position the rotary latch is released;

    a snow load device arranged in the lock, wherein the snow load device, when actuated, holds the catch in the release position until the rotary latch has reached the open position;

    wherein the catch spring is an over-center helper spring that, when the catch moves between the blocking position and the release position, reverses a direction of action of the spring force; and

    wherein the snow load device consists only of the over-center helper spring that interacts with the catch and with the rotary latch.
