A window deflector is a transparent plastic fitting, mounted above the doors of some automobiles, to protect the interior from rain or other precipitation in case of slightly opened windows. Deflectors may also be fitted to sunroofs to change the flow of air.

Types

[edit]

Based on the way wind deflectors are installed, they may be classified as follows:

In-Channel

[edit]

Installed into the upper window channel and kept in place due to tension; sometimes an additional thin strip of adhesive tape is used.

Stick-on

[edit]

The deflector has a strip of self-adhesive tape for mounting. This allows mounting a deflector above the window, to either the window frames, or the roof if the windows are frameless.

Hood protector

[edit]

A hood protector or bug guard is a similar product for protecting the paintwork on the front of the vehicle against insects.

Rear window louvers

[edit]

A Rear window louver or rear window blind (German: Heckjalousie or Heckscheibenjalousie) is a type of window blind mounted to the rear window of a car. It is intended to protect the window from dirt and restrict sunlight from entering through the rear window to reduce heat. In 1966, Lamborghini Miura became one of the first production cars that came with rear window louvers.^{[citation needed]} Rear window louvers have been criticized by some reviewers as a fashion phenomena, with little practical use.^[1]
