Abstract

The invention provides a vehicular bumper system formed by installing a collision bumper component at a vehicular bumper beam which is arranged at the front face side and has a hollow structure. The collision bumper component is provided with a collision wall part, a side wall part and a flange used for joint and is integrally formed by metal materials, and the collision wall part and the side wall part form a mode which surrounds the bumper beam and is in an approximately U-shaped section shape. The flange used for joint is jointed with a flange protruding from the back face wall of the bumper beam, and supports the collision bumper component from the back face wall side of the bumper beam. By the structure, even though the appearance size shape is narrower, the vehicular bumper system also has the function of reliably protecting human beings, such as a passerby, and the like.

Description

technical field [0001] The present invention relates to a bumper system for a vehicle body, which is excellent in absorbing load energy when the vehicle body collides with a pedestrian, and is particularly excellent in reducing the impact on the human body and reducing the damage of the pedestrian when the vehicle collides with a pedestrian. Background technique [0002] In order to ensure the safety of the occupants and protect the object being hit, a bumper system is installed on the body of a car, etc., so that when the body collides, it deforms itself in the impact direction to reduce the impact load and absorb the impact energy. [0003] As this bumper system, the typical system is composed of a bumper beam made of steel or aluminum alloy installed in front of the bumper stay, and a cushioning material made of foamed resin installed in front of the bumper. The bumper cover that is in front of it and is integral with the exterior of the vehicle. [0004] In recent years...
