A device for climbing stairs for a wheelchair having a chassis (1) having a lifting device (3) and having receivers (17, 18) for the running wheels (16) of the wheelchair on arms running transversely to the wheel axles laterally next to the chassis (1) is described. In order to provide advantageous construction conditions, it is suggested that the arms each form at least one bow (10), which is mounted so it is pivotable around a transverse axis (11) positioned in a frame (7) from a stop-delimited pivoted-out position into a positioned pivoted in against the frame (7), and the frame (7), which is linked laterally to the chassis (1) around a longitudinal axis (8), may be folded up from a stop-delimited, folded-down operating position into a rest position.
