Abstract: A motor vehicle bumper assembly according to an exemplary aspect of the present disclosure includes, among other things, a main bumper body and an actuator. The actuator includes a bracket mounted to the main bumper body, a screw jack supported by the bracket, and a trolley driven to translate by the screw jack. A lower support is mounted to the trolley. The actuator is configured to translate the lower support relative to the main bumper body from an integrated position to a deployed position.

Abstract: There is provided an under-run protector which is light-weighted and has sufficient strength, owing to a change in a plate thickness of its portion optimum for strength improvement. In an under-run protector which includes a hollow material having a rectangular cross section and mounted on a vehicle body frame via a mounting bracket, a plate thickness of a substantially horizontal surfaces forming the hollow material on a vehicle body frame side with respect to a longitudinal-direction center line of the hollow material is larger than a plate thickness of a substantially horizontal surfaces opposite the vehicle body frame with respect to the longitudinal-direction center line of the hollow material.

Abstract: The device may have a plurality of upright supports where the supports may include a mounting plate with mounting openings, a plurality of vertical members that may be in non-welded communication with the extruded back mounting plate and a plurality of horizontal members where the vertical members provide strength and support to the supports. The horizontal under-run prevention beam may include mounting openings that correspond to the horizontal beam mounting openings and a removable reflective strip that correspond to reflective strip openings in the beam. The vertical and horizontal members may be stacked extruded rectangles of the desired widths and lengths.

Abstract: An impact energy management system comprises at least a portion of vehicle structure with an impact energizable structure attached thereto. The impact energizable structure receives impact energy from an obstacle and transfers the impact energy to the vehicle structure, and has a reconfigurable engagement area extending generally vertically with respect to the vehicle structure. The impact energizable structure is reconfigurable from a first position to a second position to increase the engagement area in response to an impact between the impact energizable structure and the obstacle.

Abstract: A bumper assembly securable beneath an extended rear support bed of a vehicle wherein the bed can tilt from a horizontal orientation to a downwardly inclined position and wherein the retractable safety bumper will become retracted when the bed is in the inclined position and will be deployed for safety protection when the bed is in the horizontal position. Movement of the bumper is powered solely by a biasing device such as a spring used in combination with gravitational forces exerted upon the bumper assembly for properly coordinating movement thereof between the deployed and the retracted position with movement of the bed between the horizontal and the inclined position.

Abstract: A rear impact guard assembly for trailers for absorbing the energy of a rear impact from another vehicle including a pair of tubular vertical guards having a lower tubular horizontal tube mounted at their lower ends. The upper ends of the vertical guards are attached to a horizontal beam, which in turn is affixed to longitudinally extending side rails. The vertical guards are removably affixed to the horizontal beam and respectively removable affixed to the slide rails.

Abstract: This invention relates to a motor vehicle protector against car intrusion into its bottom. It mainly comprises two stationary frames (i.e., steady rests), two pendant arms (i.e., pending arms) and a pipe frame, wherein the upper end of the pendant arms is connected to the rear end of the stationary frame while the pipe frame is connected at the lower and rear side of the two pendant arms. The pipe frame is composed of an upper horizontal annular pipe, a lower horizontal annular pipe, a plurality of upright pipes, and multi-group piling pipes. Additionally, an warning alarm is provided at the rear end of the upper horizontal annular pipe, and a strip front fender is fixed at the internal side of the upright pipe and the lower horizontal annular pipe.

Abstract: An auxiliary protection device is attached to the rear of a semitrailer wh resists the tendency of passenger vehicles to go under a trailer upon impact in order to provide an increased measure of safety. In addition, the device to will absorb energy incrementally so as to minimize vehicle damage at low speeds but have sufficient energy absorption to safely prevent incursion at moderate speeds. The device can be moved to a retracted position to allow the trailer to back up a ramp or into a plane with the protection device retracted so as to avoid injury to the ramp.

Abstract: A crash attenuator (10) includes a plurality of layers (22) of fibrous cellular material. Each of the layers is comprised of a plurality of hexagonal elongate cells fabricated of a fibrous cellulose material that has a longitudinal axis that is disposed horizontal to the ground such that the edge of the cell is directed toward the impacting vehicle. A flat sheet of fibrous material (24) is disposed between each of the layers to provide an energy dispersing surface. A rear impact plate (18) is disposed on the impacting end of the crash attenuator (10) and is fabricated from a soft metal. A front mounting plate (20) is disposed on the opposite end thereof and the two secured by tension cables (42). The exterior of the layers (22) is covered by sheets (26) and (46). Thereafter, a layer of moisture proof material (78) is disposed over the surface of the crash attenuator (10) to prevent moisture from entering the interior.

Abstract: A front bumper for vehicles which can replace conventional bumpers to a great advantage mechanically.

Abstract: A shock absorbing apparatus suitable for use on a load carrying vehicle at the rear and/or front thereof comprises an arm pivotable to the frame or chassis of the vehicle close to the end thereof and extending downwardly to support on its lower end a horizontally disposed bumper bar extending across the vehicle, a shock absorbing device pivoted to the arm between said pivot and the bar and pivoted to the vehicle frame or chassis at a point spaced along the vehicle from said arm pivot, said three pivots forming the three apices of a triangle, lost motion means associated with at least one of said pivots to vary the configuration of said triangle to permit the arm to swing upwardly away from the vehicle frame or chassis to clear ground height variations in the path of the bar, and means to restore the arm to its normal position when the bar is clear of such ground variations.
