  • a vehicle as referred to herein can be a motor car, truck, bus, motorcycle, van, race car, aircraft, train, boat, ship or any other type of vehicle used moving at speed .and needing a windshield.
  • Windshields today are primarily one dimenaon and are provided to the front of the cabin of the vehicle characterised by extending across the vehicle as distinct from forward on the vehicle.
  • Windshields across a vehicle predominantly incur high air drag and increased injury risk from front on accidents cannot be moved to allow an open front and cause other problems such as easy to break from the outside by persons or stones.
  • This present invention aims to overcome at least in part the above referred to and other problems, and does so in the following descriptions and aspects.
  • a motor vehicle such has a conventional front position engine and bonnet, a cabin placed generally controlled lengthwise in the vehicle and the cabin having a front end and frame to which a windshield can be mounted.

Abstract

L'invention concerne un pare-brise (20) aérodynamique d'un véhicule (10), s'étendant depuis un cadre (17) situé à l'avant de l'habitable (12) de manière à recouvrir le capot (13) et à obturer ce dernier. Le pare-brise (20) est fixé à l'aide de charnières (15) au toit (11) ou au capot (13), ce qui permet l'accès au moteur du véhicule. Le pare-brise décrit dans cette invention peut remplacer ou compléter un pare-brise classique, le rebord avant (84) peut être incurvé ou droit. Lorsqu'il est installé sur un aéronef, le pare-brise décrit dans cette invention améliore les propriétés aérodynamiques à grande vitesse mais, il se rétracte au-dessus d'un pare-brise classique pour l'atterrissage et le décollage.
