A seatbelt retractor includes a spool, a piston, a cylinder, a ring, and a valve. The spool is rotatably connected with a base by the piston and the cylinder. The piston is fixed to one of the base and the spool. The cylinder receives the piston and is fixed to the other of the base and the spool. The piston and the cylinder define a first chamber. The ring is sealed against the cylinder and defines a second chamber connected with the first chamber by an aperture. The valve is disposed across the aperture.
