Seatbelt retractor having an electrically actuatable blocking device

A seatbelt retractor for a vehicle, with

• a rotatably mounted seatbelt shaft, and
• a control cam rotatably mounted on the rotatably mounted seatbelt shaft and having a toothing system, and
• an electrically actuatable blocking device comprising
• a housing having a base plate and an upright first limb, and
• a blocking lever which is pivotably mounted on the upright first limb and comprises a steel plate, wherein
• the electrically actuatable blocking device stops the control cam relative to the rotatably mounted seatbelt shaft by an engagement of the blocking lever into the toothing system of the control cam, thereby blocking the rotatably mounted seatbelt shaft in a pull-out direction, and wherein
• the blocking lever has a lever arm that projects outward from the first limb and on which a first end of a first spring acts, which preloads the blocking lever into a position in which it engages into the toothing system of the control cam with a blocking tip arranged at the end of a blocking arm, and
• an electromagnet arranged in the housing, which exerts a force on the blocking lever by energization, by means of which force said blocking lever is pulled out of the toothing system of the control cam together with the blocking tip,
• wherein
• a projection is provided on the housing, and is shaped in such a way that the first spring bears against it independently of the position of the blocking lever and is preloaded transversely with respect to the spring force exerted on the lever arm.
