The invention relates to a safety belt device for a vehicle, having a belt force limiting unit (13), which is designed as a piston/cylinder arrangement comprising a piston tube (23) and a piston (25), which in the event of the belt force being limited, in particular in the event of a crash, can be displaced in the piston tube (23) for a force limiting distance (s) while expanding and being plastically deformed, such that the belt force (F) exerted on a vehicle occupant is limited to a pre-defined force level. According to the invention, the safety belt device has a switching unit (36), by means of which, in particular in a pre-crash phase, the force level profile (F(s)) can be predefined via the force limiting distance (s) depending on the height and/or the weight and/or the sitting position of the vehicle occupant.
