FRONT DAMPING AUTOMOTIVE GUARD AND DAMPING CARTRIDGE FOR IT Russian patent published in 2011 - IPC B60R19/02 E01F15/14 

FIELD: transport.

SUBSTANCE: invention relates to automotive passive protection means. Proposed guard comprise frame with attachments to vehicle or stationary structure, and damping cartridge jointed to said frame. Damping cartridge comprises case with means to absorb energy generated in collision. Damping cartridge rear section serves to interact with vehicle driven into guard. Its central section serves to decelerate and absorb kinetic energy due to deformation and destruction of energy absorbing means. Its front section serves to limit cartridge deformation and to be attached to base component of road front guard. Cartridge central part energy absorbing means are formed by vertical shaped sheet elements with beads oriented in crosswise direction relative to cartridge lengthwise axis and in opposite direction relative to adjacent elements. Beads of shaped sheet elements are formed by walls and vertical flanges. Adjacent shaped sheet elements are jointed together along vertical flanges either directly or via flat sheet elements to form cells between inclined walls and flanges of adjacent shaped sheet elements. Cartridge front section located on the side of base component of road front guard represents a frame with stiff traverse element. Cartridge rear section represents a 3d module made from thin-sheet material with trapezoidal cross section filler with porous filler. 3d-module vertical flange is jointed with vertical flanges of adjacent shaped sheet element of cartridge central section.

EFFECT: higher safety.
