A fluid damper for modulating a retaining force of a seat belt is provided. The fluid damper includes an outer cylinder and an inner cylinder. The inner cylinder encloses an inner space. The fluid damper includes a piston shiftable in the inner space. The fluid damper includes a duct. The duct conductively connects a front fluid chamber disposed in front of the piston to a rear fluid chamber disposed behind the piston and/or a reservoir for the damping fluid. The duct includes an outer duct portion and an inner duct portion. The inner cylinder is deflectable from a rest position by a force acting on the piston so that the deflection of the inner cylinder causes an adjustment of an overlap of the outer duct portion and the inner duct portion depending on the magnitude of the force.

A self-regulating damper unit comprising a cylinder having a first working chamber and a second working chamber, a piston, a piston rod, and a through-hole between the first working chamber and the second working chamber. The damper unit also comprises a shiftable weight which modifies a passage cross-section of the through-hole. The shiftable weight is movably mounted such that retardation of the piston causes enlargement of the passage cross-section. A seat belt unit comprises a seat belt and the damper unit.
