DEPLOYABLE STIFFENER OF VEHICLE FRONT BUFFER FOR PEDESTRIAN PROTECTION Russian patent published in 2018 - IPC B60R21/34 B60R19/26 B60R19/40 

FIELD: motor vehicle industry.

SUBSTANCE: group of inventions relates to the field of transport machine building. In the first embodiment, the front-buffer system of the vehicle having the front frame members supporting the buffer bar contains linear actuators and a stiffener for protecting the pedestrian. Linear actuators are mounted adjacent to the front frame members and are extendable along the displacement axes extending forward and downward relative to the vehicle. Stiffness element for pedestrian protection is connected to the actuators for linear movement. In a second variant, the vehicle front buffer system comprises an actuator mounted on the vehicle frame behind the buffer. Buffer rests on the frame. In a third variant, the vehicle front buffer system includes actuators having pistons and a pivot hinge defining a horizontal pivot axis around which the front portion of the piston rotates.

EFFECT: improved safety when colliding with a pedestrian is achieved.
