1. Erecting mechanism for a swivel-up rollover bar for vehicles having a bar leg which is supported in a swivel bearing on one vehicle side, said bar leg being swivellable about a transverse axis of the vehicle and having a supporting section remote from its swivelling axis which serves to support the vehicle during a rollover movement, wherein the bar leg is supported by a support assembly such that, during swivelling-up of the rollover bar to a vehicle supporting position, the supporting section of the bar leg describes a curved path which deviates from a circular arc around the swivelled bearing at least over a partial range of its swivelling angle to thereby change the effective length of the bar leg with respect to a vehicle structure in response to its swivel position, and wherein said supporting structure includes a cam driven swivellably about a cam bearing point and serving to displace the bar leg in a longitudinal direction of the bar leg, wherein the cam is formed by an eccentrically swivel-mounted disc.
