Actuation unit for motor vehicle door lock, has draw roller and supply roller mechanically coupled with each other by drive unit, where supply roller is formed as winding and unwinding rollers for drive unit with winding and unwinding radii

摘要

The unit has a flexible drive unit (4) working in sense of a linear adjustment on a draw roller (9). The draw roller and a supply roller (5) are mechanically coupled with each other by the drive unit driving about the draw roller in a space variable manner. The draw roller is rotatably supported in a linear positioning unit (11) that comprises a transmission unit (14), where the positioning unit is adjustably supported and guided in a drive housing. The supply roller is formed as a winding roller and an unwinding roller for the drive unit with different winding radius and unwinding radius.
