AUTOMOBILE ENERGY-ABSORBING BUMPER WITH GUARD Russian patent published in 2006 - IPC B60R19/18 B60R19/36 F16F7/12 

FIELD: transport engineering; automobile protection means.

SUBSTANCE: proposed bumper connected to load-bearing structure of automobile includes two sections arranged at a distance from each other and energy-absorbing device adjoining each other. Each energy-absorbing device consists of two interconnected energy-absorbing members, each being mirror image of the other and made as integral part from cut of round metal bar including base, additional base, near, additional and far bridges interconnected by main and additional braces and located in relatively perpendicular planes. Bases of energy-absorbing members are arranged vertically and connected to support surface, bridges of energy-absorbing members are arranged horizontally coaxially relative to each other, main and additional braces of energy-absorbing members of each section are arranged lower than support surface being inter connected by rigid plates. Each section of bumper is provided with guard made up of interconnected vertical and horizontal tubular members connected to additional bases of energy-absorbing devices and shock-absorbing devices connected to tubular members of guard and load-bearing structure of automobile and made integral of two leaf springs. Bumper includes outer sheathing with thinning sections to provide order destruction in preset places and elastic resilient members in form of cylinders connected to tubular members of guard.

EFFECT: simplified design, provision of high energy-absorbing properties and stability of shock absorbing, possibility of repeated use of structure.
