Embodiment Construction

[0038] The present invention is explained below with reference to exemplary embodiments and reference examples. However, the present invention is not limited to this exemplary embodiment.

[0039] A first structure corresponding to the prior art was simulated by computer. The weight of the head 1 is 4.8 kg. The head hits at a speed of 35 km / h the fixed metal plate 2 which is flexible compared to the vehicle components 3 arranged in the vehicle body. The sheet metal 2 is made of 0.7 mm thick steel and is part of the car body. A non-flexible rigid vehicle component 3 is arranged behind the body interior sheet metal. The separation distance between the vehicle component 3 and the metal plate 2 is 55 mm.

[0040] Computer simulations showed a HIC value of 41,000. The dashed line in Fig. 2 shows the temporal characteristics of the head velocity. Shown is a curve of speed in [km / h*10] and time t in [second]. The solid line plotted as a function in Figure 2 shows the accelerat...

Abstract

The invention relates to a device for reducing injuries to vehicle occupants in the event of an accident with a motor vehicle.

Description

technical field [0001] The present invention relates to devices for reducing injuries in motor vehicle accidents. Background technique [0002] When a pedestrian or passer-by is hit by a motor vehicle, the collision between the person and the body of the motor vehicle can cause injury. In Europe, approximately 7,000 pedestrians are killed each year as a result of such collisions with passenger vehicles. The leading cause of death was injury to the head. According to accident statistics, for pedestrians, 80% of all fatal injuries are due to impact of the head on the hood or A-pillar. In 95% of such impacts, the speed of the vehicle is below 60 km / h; the statistical average is about 40 km / h. [0003] In order to reduce such fatalities, motor vehicles should be designed in such a way that in the event of a collision between a pedestrian and a vehicle moving at 40 km / h, the so-called head injury criterion (HIC value) is within 100% of the exactly defined surface area of ​​the...
