Abstract: A bumper system for a vehicle is installed on the front and rear of a vehicle frame. The system prevents a crash impact force from being transmitted to the vehicle body by absorbing such impact force. The system has a bumper assembly and bumper supporters or deflectors located between the bumper assembly and the frame. The bumper assembly has transverse portion and side portions. Each of the bumper supporters has a shaft portion fixed to the frame, and a supporting member pivotally mounted about the shaft. The supporting member has first and second arms which are integral to and opposite each other and support the transverse and side portions of the bumper assembly. The bumper supporters push the lateral sides of the bumper assembly outwardly by force transmitted to the bumper assembly during a collision, thereby preventing the body adjacent to the bumper assembly from being damaged.
