Abstract
A recoil blocking device for vehicles (1) for roller-coasters, monorails or the like. To avoid the ratchet noises occurring in the case of prior-art ratchet-type blocking mechanisms of such recoil blocking devices, the present invention provides a catch drive (21), which is designed as an eddy current drive and spaces the catch (2) from the countercatch (5) when the vehicle (1) is moving forward and allows the catch (2) to engage the countercatch (5) when the vehicle (1) is standing or moving backward. The catch (2) is mounted rotatably at the vehicle, whereas the countercatch (5) is arranged stationarily in the form of a toothed rack in the area of the rail arrangement (4) of an uphill section.
