In a device (1) for the actuation of vehicle brakes, with a pull element (2) which can be brought into a lockable braking position in order to pull at least one braking means of the vehicle brakes, the pull element (2) being capable of being tensioned by a tension element (3) in this braking position, and which can be brought into a released position, in which the pull element (2) is relaxed to an extent such that the braking means is released, the device being provided with a retensioning device which, in the released position, automatically rentensions the pull element. The automatic resetting operation should take place as continuously as possible. This is achieved in that, that the tension element (3) is provided with at least one gripping means (4) which, in the braking position, acts non-positively on the tension element (3) under the spring effect of a first spring element (6), in that, that in the released position, the gripping means (4) can be released from the tension element (3) in such a way that the gripping means (4) slides over the tension element (3), and in that, that in the released position, the tension element (3) is arranged so as to be movable under the effect of a second spring element (7) in such a way and the spring force of the second spring element (7) is dimensioned in such a way that the pull element (2) is automatically retensioned. |
