Abstract: A motor vehicle including a passenger compartment is rendered collision resistant by a wedge member formed at the front of the vehicle defined by a forward most apex designed to run close to the ground, a rigid pan extending horizontally backwardly from the apex underneath the vehicle and an inclined ramp which extends upwardly and rearwardly from the apex to a position over the passenger compartment. The suspension of the vehicle is arranged so that on engaging an oncoming vehicle or the like the apex is forced downwardly to engage the pan with the ground so that the ramp acts to allow the oncoming vehicle to run up and over the vehicle while the vehicle continues to slide forwardly on skids or rollers on the underside of the pan.

Abstract: The present invention relates to a protective roller device for attachment to various kinds of vehicles for prevention of injuries to persons or damages to objects encountered in traffic accidents when persons may stumble or objects may fall under the area of the wheel of the vehicle. The device comprises a set of vertical and parallel arranged protective rollers to be fixed on the car body at a location proximate to the car wheels. The said protective rollers consists of a center shaft and an elastomeric buffer component sheathed around the said shaft for free rotate thereabout. When equipped with said protective roller devices, the car is able to gently push the persons or objects encountered out of the dangerous wheel area and to prevent injuries or damages.
