Abstract

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.
