Abstract
A seatbelt retractor including a frame, a retracting shaft rotatably coupled to the frame which retracts a seatbelt thereon, a locking gear coupled to the retracting shaft, a first and a second pawl provided adjacent to the locking gear and independently rotatably coupled to the frame such that when the first and second pawl rotate they engage with the locking gear and prevent rotation of the retracting shaft in the extending direction. A rocker arm pivotably supported at a pivot point and having a first catch pin at one end thereof which engages with a portion of the first pawl and a second catch pin at the other end thereof which engages with a portion of the second pawl such that the first pawl is caused to engage with the locking gear when the rocker arm rotates in one direction about the pivot point and such that the second pawl is caused to engage with the locking gear when the rocker arm rotates in the other direction about the pivot point and an acceleration sensing member which causes the pivot point to move during a motor vehicle emergency such that at least one of the first and second pawl is caused to rotate.
