Abstract
A support unit for the fastening of a diverting roller to a support structure can be used for supporting a car in an elevator installation. The support unit has two yoke beams and a bearing for the diverting roller. The yoke beams are arranged parallel to one another for fastening to the support structure. On the support unit there are at least two restraint devices that are fastened to the yoke beams and which project into the intermediate space between the yoke beams such that, in the event of failure of the bearing, the restraint devices form a stop to prevent the diverting roller from moving in a support direction under the action of the support force. The support unit is stable, is of simple construction and is of space-saving design.
