An inflatable, window-covering system is described. The inflatable, window-covering system may include an inflatable cushion and a drive assembly, the drive assembly including a power source; one or more sensors, where the one or more sensors may be configured to detect a triggering event; and an air pump configured to inflate the inflatable cushion based, at least in part, on the detected triggering event. In some cases, the triggering event may include any of sensing a predetermined temperature, sensing a predetermined level of light intensity, sensing a predetermined time, or receiving an instruction, or any combination thereof.

A vehicle side window shade for mounting on the side window to block the sun and heat from entering the vehicle through the side window. It comprises a foldable, opaque cloth, with a plurality of thin, rigid yet flexible tabs attached to at least one of its edges. Installing the sunshade on a car's side window is done by wedging the tabs vertically into the upper edge of the window's frame, such that the top of each tab is pressed between the window's glass and the flexible rubber seal which lines the window's frame in the door.

The novelty of the invention lies in the combination of a foldable cloth and rigid yet flexible tabs, forming an effective and convenient vehicle side window shade.

A roller shade may be retracted and extended. In various implementations, when a roller shade is extended it may be laterally repositioned. The roller shade may include a track and a travelling member.

The invention relates to stackable slats for directing light as a preliminary product for blind sun protection hangings for directing light: the slats are folded in the longitudinal direction and have a lateral light shadow side and a lateral light irradiation side vis--vis lateral light from the upper half-space. At least two slats lying one on top of another have at least partly a fold-shaped contour zone K, in which the slats are able to be placed one on top of another shape-complementarily, and also at least one edge zone RZ. An upper slat lying on a bottom slat in the installation state at least in an edge zone RZ on the lateral light incidence side has at least one larger fold angle 3 and/or 4 relative to the contour zone K. At least one edge zone RZ of a top slat is shaped differently from an edge zone RZ of a bottom slat. With the slat preliminary products bifocal blind sun protection hangings are producible, by means of which in the lower hanging region through the bottom slats lateral light is able to be reflected back substantially into the half-space of the light incidence and in the upper region of the blind sun protection hanging through the overlying slats lateral light with high angles of incidence from the sun is able to be reflected at least partly into the half-space opposite the lateral light incidence. Lateral light incidence is able to be reflected back into the half-space of the light incidence by way of the shape-complementary contour zone K.
