Shading device for an automobile with declutching winding tubes, and corresponding motor vehicle

摘要

The device has occultation screens (21, 22) mounted on winder tubes carried by housings or semi-cassettes (11, 12), respectively. Locking units e.g. pivot, block rotation of the tubes when the device is in a storage position. Releasing units e.g. rods, act on the locking units to allow rotation of the tubes to actuate or ready to actuate when the device is in working position. Each locking unit comprises a locking piece integrated to the tubes so as to engage with another locking piece secured to the housings.
