MOBILE FRONTAL FENCE Russian patent published in 2023 - IPC B60R19/54 B60D3/00 

FIELD: energy-absorbing devices.

SUBSTANCE: mobile frontal fence is made in form of a wheeled trailer, on the frame of which energy-absorbing elements are placed. The frame is made of interconnected front frame and rear frame. The front frame is made in form of a coupling device with a coupling loop mounted on the front frame by means of a telescopic energy-absorbing element, on both sides of which end stops are installed. The coupling loop protrudes beyond the end stops along the axis of the frame. The front frame is mounted with the possibility of axial movement along the longitudinal elements of the frame mounted on the rear frame. At least one wheel axle is installed on the rear frame, as well as at least one energy-absorbing element of the first row. At least one energy absorbing element of the second row is installed between the front frame and the rear frame.

EFFECT: reduced inertial overload and improved safety.
