Rotary motion brake for motor vehicle seat, has disk spring for tensioning in sliding direction, where difference of brake torques is produced by detention force and/or sliding friction force in disks and spring

摘要

The brake has disks (6, 7) converting a relative rotating movement of parts into a sliding movement coaxially running relative to an axis of rotation. A disk spring is provided for tensioning in a sliding direction. Brake torques are developed based on the direction of rotation of the brake. A difference of the brake torques is produced by a detention force and/or a sliding friction force in the disks and the spring.
