Abstract

The invention relates to a load torque lock (1) comprising a sling element (12) that frictionally interacts with a brake component (13) for blocking a torque, and a drive wheel (14) that is coupled in a torque transferring manner to a carrier (15; 15a) having at least one contact area (25) to the sling element (12) and engaging axially in the drive wheel (14), by means of which a torque to be blocked can be initiated in the sling element (12). According to the invention, the carrier (15; 15a) has means for reducing the bending tension in the at least one contact region (25).
