Abstract: The invention relates to a device (5) for supporting and for movably guiding a chair (6) in a slotted guide (8, 8.1, 8.2), which is provided in a housing (7) and is designed as an elongated hole guide, having a carriage (10) that can be moved in the slotted guide (8, 8.1, 8.2) and supports a chair receptacle (9) of the chair (6). In order to be able to use this device in a more varied manner, according to the invention, the slotted guide (8, 8.1, 8.2) has at least two slotted guide tracks (13, 14), between which an adjustable track switch (12) is provided in order to transfer the chair (6) out of the one slotted guide track (13) into the other slotted guide track (14), and vice versa.
