Abstract: A self-coiling dent guard for protecting vehicles and other objects from damage caused by unwanted collisions is disclosed. The guard is comprised of a main body adapted to absorb the impact of colliding objects. A bistable spring strip is integrated within the main body of the guard, thus giving the guard its self-coiling properties. When not in use, a user may cause the guard to coil so as to be easily stored. A magnetic strip is attached to the length of the main body such that the guard may be removably attached to a vehicle or other object. A layer of felt covering the bottom of the guard protects the vehicle from being scratched when the guard is applied or removed.

Abstract: A bumper for a vehicle is disclosed. The bumper includes a housing that has a pair of interlocking supporting frames. One of the supporting frames is fixed to the vehicle body. The bumper includes a plurality of rebounding elements and a plurality of biasing elements, each that are fixed within one of the supporting frames of the housing. Each of the rebounding elements has a predetermined rebounding elements spring coefficient. The plurality of biasing elements has a biasing elements spring coefficient that is not equal to, and is preferably less than, the spring coefficient of each rebounding element. Further, each of the biasing elements abuts one of the rebounding elements. As such, as the interlocking supporting frames of the housing are compressed in a vehicle collision, the plurality of rebounding elements together with the plurality of biasing elements absorb the collision energy and are each compressed at different rates.

The bumper reinforcement member has a first lateral end section, a second lateral end section, an outboard facing side extending between the first and second lateral end sections and an inboard facing side with a vehicle mounting structure. The corner bracket is pivotally supported to the first lateral end section of the bumper reinforcement member proximate the inboard facing side. The biasing member extends between the outboard facing side of the bumper reinforcement member and an outboard side of the corner bracket. The biasing member biases the corner bracket outwardly relative to the vehicle mounting structure to a normal rest position for absorption of low speed impact energy.

During deformation, the primary beam-column slides into the secondary beam-column having a central channel that accommodates the primary beam-column.

Abstract: A pneumatic energy absorbing arrangement, for use between the bumper and the frame of an automobile, includes a piston and cylinder combination which provides for an increasing amount of force or energy absorbed in relation to an increasing amount of travel between the piston and cylinder combination and, therefore, of the automobile itself. Exhaustion of the air within the piston cylinder combination is accomplished by a decreasing area of vent holes as the travel of the piston and cylinder increases. A specific or variable rate spring is provided to bias the piston and cylinder arrangement in an extended before-impact condition and absorb energy. The energy absorption device provided by this invention is reusable in that it is not destroyed during an impact.

Abstract: A movable molding is provided for a vehicle on the vehicle body adjacent to a wrap-around end portion of the bumper. The molding and end portion of the bumper have mating abutment walls through which these elements are fastened together. When the bumper moves towards the vehicle upon impact, the molding is thereby caused to move therewith. Slide elements are provided between the molding and vehicle body for sliding of the molding along the body. A fastening element attaches the molding to the bumper end portion. The fastening element comprises a tensioned flexible cable which permits vertical movement of the bumper end portion with respect to the molding.

Abstract: The collision protection device comprises a collision protector held in a rest position by spring force. Upon collision against an obstacle, the collision protector is displaced against the spring force and thus cooperates with a de-energizing device. This collision protector is mounted on the vehicle chassis by two swing arms arranged symmetrically non-parallel or in angled relationship to the longitudinal axis of the vehicle. This is to permit the de-energizing device to function effectively, irrespective of the place of impact of the obstacle against the collision protector and irrespective of any deformation of the collision protector. Each swing arm is pivotably mounted on the collision protector and on a sliding link member. Each sliding link member is acted upon by the spring force and is displaceably positioned on a cross-shaft mounted on the vehicle chassis perpendicular to the longitudinal axis of the vehicle.
