A trailer includes front and rear ends spaced in a longitudinal direction to define a cargo area. A frame includes a rear bolster extending in a transverse direction across the rear end below a bottom rear edge of the cargo area. Spaced rear frame posts extend upwardly from respective distal ends of the rear bolster. A rear impact guard includes a bumper extending transversely and spaced below the rear bolster, a pair of outboard posts extending between the bumper and the rear bolster adjacent the respective distal ends of the rear bolster, and at least one inboard post. Each of the outboard posts has a rearward-extending horizontal first flange and an upward-extending vertical second flange spaced forwardly of the first flange, these flanges including multiple apertures aligned with apertures in the trailer frame, each of the apertures accommodating a removable fastener securing the rear impact guard to the trailer frame.

A mounting system for a guard panel on a vehicle with cross members. The mounting system comprises a mounting rail having first and second ends. The mounting rail includes a clamping portion including a mounting platform, a mounting slot in the mounting platform along a length of the mounting rail between the first and second ends, and a panel portion. The mounting system includes a panel bracket coupled to the panel portion. The panel bracket receives at least one guard panel. The mounting system includes a clamping body coupled to the mounting platform. The clamping body is movable along the mounting slot of the mounting platform. The clamping body engages a first surface of a cross member and the mounting platform engages a second surface of the cross member so as to clamp the cross member between the clamping body and the mounting platform.

In a truck having a plate-like side guard disposed at each of the right and left side faces of a vehicle body and arranged apart from the lower face of a cargo bed, a flexible sheet having a rectangular shape is attached between the cargo bed and the side guard. The sheet has one end portion in the vertical direction secured to one of the cargo bed and the side guard, and the other end portion in the vertical direction detachably fastened to the other of the cargo bed and the side guard.

[Object] To improve load resistance performance in response to collision. [Solution] An end structure of a vehicle according to the present invention includes: a beam 2 that extends in a vehicle width direction; and a connecting structure 3 that connects the beam 2 to a vehicle body frame. In a cross-sectional view perpendicular to the vehicle width direction, the beam 2 includes a first top surface part 2a and a first bottom surface part 2b which face each other, a first side surface part 2c that connects one ends of the first top surface part 2a and the first bottom surface part 2b, and first flange parts 2d that are formed to protrude vertically outwardly at the other ends of the first top surface part 2a and the first bottom surface part 2b. The beam 2 is fixed to the connecting structure 3 by at least one of bonding of a protrusion 6 that is provided in the connecting structure 3 and is arranged to protrude inside the beam 2 to the first top surface part 2a and the first bottom surface part 2b and bonding of a beam attachment member provided in the connecting structure 3 to the first flange parts 2d.

A secondary bumper assembly is provided and includes a base plate, a secondary bumper, and heel blocks. The base plate includes holes for mounting the secondary bumper assembly to a primary bumper. The secondary bumper is disposed on the base plate. The secondary bumper includes a main body and a base. First and second grooves exist between portions of the main body and the base, which has base segments. The heel blocks include flanges and maintain contact between or at least partially prevent movement between the secondary bumper and the base plate. The base segments slide into gaps between the base plate and the heel blocks. A hardness level of the base segments is greater than a predetermined level to prevent flexing of the base segments in a direction away from portions of the main body opposite the base segments. The flanges slide respectively into the first and second grooves.

Devices and methods are disclosed for detecting or predicting an underride impact. An example vehicle includes a camera for capturing an image of a target vehicle, sensors for detecting a speed and heading of the vehicle, and a processor. The processor is configured to determine a target vehicle classification, determine an open space of the target vehicle, determine a closing speed between the vehicle and target vehicle, predict an underride impact based on the classification, open space, and closing speed, and responsively execute an impact action.

A selectively deployable lower rear bumper for the back end of a school bus. The deployable bumper is mounted using a support frame including mounting holes for connection to the bus frame and a deployment frame is moveably connected to the support frame. A bumper bar is connected to the deployment frame and a deployment motivator is connected to the support frame and the deployment frame to move the bumper bar between a retracted position and an extended position. Various circuit interfaces are electrically connected to the bus circuit and the deployment motivator for automatic operation of the deployment motivator.

A side underride system configured to be coupled to a trailer is disclosed. The side underride system comprises a support system configured to be positioned below the trailer to provide side underride protection. The support system includes a cable system and a brace system. The cable system is configured to couple to the trailer. The brace system includes a plurality of cross-braces that each extend at least partially across a width of the trailer, are spaced apart at intervals along a length of the trailer, and are configured to capture the cable system.
