Abstract: A knee restraint device for vehicles comprises a base, a knee protector component which is movable towards the knees of a vehicle occupant, a drive means which is arranged between the base and the knee protector component, and catching and positioning means which control the movement path of the knee protector component at least in the up/down direction relative to the vehicle and which, in the limit of travel of the drive means, define a predetermined end position of the knee protector component in the space. To provide a knee restraint device which accomplishes the controlling of the movement path and the definition of the end position of the knee protector component and which can be adjusted in a simple manner to various end positions of the knee protector component, the catching and positioning means are arranged outside the drive means and the drive means loosely contacts the knee protector component.
