In urban traffic accidents, mainly pedestrians and cyclists are at risk of being injured and killed. Lethal injuries are usually caused by the immediate impact of a car or a tram. This paper presents a fatal accident without any direct contact with a motor vehicle. A 63-year-old woman sitting on a chair in a pavement cafe was killed by the impact of a 60-year-old male cyclist, who was flung in her direction after colliding with a car. Autopsy yielded intracutaneous haemorrhages on the impact sites of the female victim (left cheek, left shoulder and left upper arm). The woman sustained a ring fracture of the skull base encircling the foramen magnum with subtotal severance of the brain stem and massive chest trauma. All the injuries were caused by the blunt impact of the moving human body. The head was forcibly bent towards the contralateral shoulder resulting in a depression fracture of the skull. Reconstruction of the accident at the scene was challenging, as the fatally injured victim remained sitting on the chair and did not show any striking external signs of traumatisation. According to the assessment of the technical expert, the collision velocity of the moving body amounted to 6-8 m/s.
在城市交通事故中，主要是行人和骑自行车的人面临受伤和死亡的风险。致命伤通常是由汽车或电车的直接撞击造成的。本文介绍了一起与机动车没有任何直接接触的致命事故。一名63岁的女性坐在人行道咖啡馆的椅子上，被一名60岁的男性骑自行车者撞击致死，该骑车者在与一辆汽车相撞后被甩向她的方向。尸检发现女性受害者的撞击部位（左脸颊、左肩和左上臂）有皮内出血。该女子颅骨底部环绕枕骨大孔处出现环形骨折，脑干部分离断，胸部有大面积创伤。所有损伤均由移动人体的钝性撞击造成。头部被强行弯向对侧肩部，导致颅骨凹陷性骨折。由于致命受伤的受害者仍坐在椅子上，且没有明显的外部创伤迹象，因此在现场重建事故具有挑战性。根据技术专家的评估，移动人体的碰撞速度为6-8米/秒。
