Extendible structural part for a motor vehicle

摘要

A structural part for a motor vehicle includes an inner component having a generally rectangular cross section and configured in the form of a multichamber hollow section made of light metal, and an outer component having a generally rectangular cross section. The inner and outer components are movable in a telescoping manner relative to one another between an idle state and an activated state. A first locking mechanism is provided to lock the idle state and a second locking mechanism is provided to lock the activated state. The movement of the inner and outer components from the idle state to the activated state is hereby realized by an actuator.
