Embodiment Construction

[0019] figure 1 is a perspective view of a windshield 10 according to an embodiment of the present invention. The windshield 10 is curved in both the horizontal and vertical planes.

[0020] The windscreen has an upper edge 11 and a lower edge 12 . It should be noted that when the words "upper" and "lower", "horizontal" and "vertical" are used, they are relative to the windshield in this specification, which means Windshield when inside the car.

[0021] exist figure 1 In an embodiment of the invention, the windshield includes a break line 13. This fracture line 13 is arranged to weaken the windscreen 10 so that it breaks in a controlled manner in the event of a collision with a person (not shown). This will result in a damaged and softened windshield preventing serious injury to the person striking the windshield.

[0022] Preferably, the break line is arranged along the longitudinal direction of the windshield, such as figure 1 shown in . The advantage of the longitu...

Abstract

A windshield (10, 20, 30, 41) for a vehicle (40) comprises weakening means (13; 22; 42) arranged to weaken said windshield so that the windshield collapses in a controlled manner in the event of the vehicle (40) colliding with a person.

Description

technical field [0001] The invention relates to a windshield for a vehicle, and to a vehicle having such a windshield. Background technique [0002] Cars today are getting safer every year. Today they are equipped with airbags, seat belts, sirens to detect nearby obstacles. Generally, safety measures are aimed at protecting motorists and their passengers. However, some well-known car manufacturers are also concerned about safety measures for pedestrians. An example is automatic braking in situations where a car system detects a dangerous situation. In such a situation, the car will apply the brakes even before the driver realizes the danger. Even with this technology, pedestrians may strike the windshield during an accident. [0003] Due to the curved shape, that is, the convex shape, today's windshields are very strong and can cause serious injuries when a pedestrian hits the windshield. So there is a need to further improve the safety of cars and other vehicles to re...
