A gear stage (14) for a vehicle seat, in particular for a motor vehicle
seat, has a driving shaft (16) and a driven shaft (18). The gear stage
(14) reduces the rotational speed of the driving shaft (16) to a lower
rotational speed of the driven shaft (18). The gear stage (14) comprises
at least one row (24) of transmission balls upon which tangentially lie
at least one, and in particular two driving surfaces (22) of the driving
shaft (16), at least one driven surface (26) of the driven shaft (18) and
at least one housing surface (28) of a housing (32).
