Belt Retractor
First Claim
1. A belt retractor comprising a rotatable belt roll, a rotary member that can be connected to the belt roll in a torsion-proof manner, and an actuator that generates an actuating force and acts upon at least one frictional element in order to engage the frictional element with the rotary member that can be connected to the belt roll in a torsion-proof manner so as to decelerate a rotational movement of the belt roll, wherein an arrangement for self-reinforcing the actuating force generated by the actuator is disposed between the actuator and the rotary member.

Abstract
A belt retractor (10) is suitable especially for use in an adaptive seat belt system and has a rotatable belt roll (14), a rotary member (18) that can be connected in a torsion-proof manner to the belt roll (14), and an actuator (32; 72) which generates an actuating force and acts upon at least one frictional element (22, 22′) in order to engage said frictional element (22, 22′) with the rotary member (18) that can be connected in a torsion-proof manner to the belt roll (14) so as to decelerate a rotational movement of the belt roll (14). An arrangement for self-reinforcing the actuating force generated by the actuator (32, 72) is disposed between the actuator (32; 72) and the rotary member (18).
