Collision object for use as board-like two-dimensional foam material barrier to check e.g. sensor systems of passenger car, has frame structure with pressurized air-filled tubular elements and complemented to closed body by cladding element

摘要

The object (1) has a frame structure (2) comprising pressurized air-filled tubular elements (2.1), where the frame structure is complemented to a closed body by a cladding element (3). The cladding element comprises openings (3.2), which are closed by cover elements (3.3). The frame structure and the cladding element are filled with air, where pressure of the air corresponds to surrounding pressure. The cladding element is made of plastic, and the pressurized air-filled tubular elements are detachably connected together by Velcro(RTM: hook-and-loop fasteners). An independent claim is also included for a collision unit for checking of a sensor system and collision-avoiding or damage-reducing assistance systems of a vehicle.
