A self-locking belt retractor for a seat belt device of a motor vehicle with a belt shaft body and a profile head, and a blocking device with a blocking catch mounted on the profile head. When activated, the blocking device engages in a blocked position with a vehicle-affixed interlock for the purpose of blocking the belt shaft in the belt extension direction. A force-limiting device is disposed in the force transmission path from the belt shaft body to the blocking catch. The profile head is made as two parts, with a carrier component and an insert component which are affixed together. The insert component exhibits a higher resistance to deformation than the carrier component and, when the belt shaft is blocked, forms part of the force transmission path between the blocking catch and the force-limiting device.
A self-locking belt retractor for a seat belt device of a motor vehicle comprising, a belt shaft body and a profile head, and a blocking device with a blocking catch mounted on the profile head, which when in an activated condition engages in a blocked position with a vehicle-affixed interlock for the purpose of blocking the belt shaft in a belt extension direction, and a force-limiting device disposed in a force transmission path from the belt shaft body to the blocking catch, the profile head is formed of two parts, with a carrier component and an insert component that is non-rotatably connected with the carrier component, the insert component exhibits a higher deformation resistance than the carrier component and forms a part of the force transmission path when the belt shaft is blocked.
