US Patent 9718340 Underfloor unit for a motor vehicle

An underfloor unit (10) for protecting components of a motor vehicle, in particular a traction battery for electrically driving the motor vehicle, from ground impacts is provided. The underfloor unit (10) has a floor panel (12) for covering the motor vehicle component on the ground side and a plurality of separate impact protection tiles (16) connected to the floor panel (12) and intended for taking up ground impacts. As a result of the multiplicity of impact protection tiles (16), only individual impact protection tiles (16) need be exchanged on being subjected to a hard absorbed ground impact, thus making it possible to have a motor vehicle with low maintenance and/or repair costs.
