LOAD LIMITING SEATBELT RETRACTOR

A vehicle includes a seatbelt retractor including a housing and a spool rotatably supported by the housing. The seatbelt retractor includes a load limiter fixed to the spool and lockable with the housing. The load limiter has a first coupling and a second coupling spaced from the first coupling on the rotational axis. The first coupling has a first energy absorber retained in a first cavity. The first energy absorber is compressible relative to a first male segment and a first female segment of the coupling. The second coupling has a second energy absorber retained in a second cavity. The second energy absorber is compressible relative to a second male segment and a second female segment of the second coupling.
