Crash attenuator for protecting a truck or stationary structure from damage resulting from impact of an object including a frame mountable to the structure, a bumper having an impact-receiving face adapted to receive an impact from the object, a movable displacement structure interposed between the frame and bumper and having a first position in which the bumper is relatively distant from the frame and a second position in which the bumper is relatively proximate to the frame, and an energy dissipation system coupled to the displacement structure for dissipating impact energy of the object received by the bumper which causes the displacement structure to be moved from the first position toward the second position. The energy dissipation system includes one or more deformable members which deform upon movement of the displacement structure from the first position toward the second position with such deformation causing dissipation of impact energy.

A truck mounted attenuator (TMA) is constructed to minimize length during use in a horizontal position and height in a vertical transport position, as well as to minimize wind resistance and buffeting at highway speeds. A modular construction is employed, so that only damaged portions of the TMA can be removed and replaced in the field after a vehicle impact. The TMA comprises a plurality of outwardly curved tubular structural members which are designed to buckle upon application to the TMA of forces resulting from vehicular impact. The rigid tubes buckle at a high initial force, then proceed to crush at a lower force once the sides have buckled outwardly sufficiently to protect vehicle occupants during the critical first two feet of travel after impact. This design also provides increased protection for errant vehicles which impact the TMA device from an angle (i.e. “coffin corner” impact).

The vehicle impact attenuator comprises at least two impact absorber bodies for transforming impact energy which acts along a central impact axis, into deformation energy. The bodies are arranged in pairs, and the bodies of each pair are located on either side of a central axis of the device, and are mechanically interconnected in such a way that the deformation of one of these bodies due to a crashing vehicle results in a deformation also of the other absorber body, induced by said mechanical interconnection.

A trailer-mounted crash impact attenuator is disclosed for attachment to a host vehicle, which comprises an anti-rotational attachment system having an internal support tube and a plurality of external support tubes. The internal support tube has a connector on a front end thereof for attachment to a suitable receptacle on the host vehicle, and the plurality of external support tubes each have an anti-rotation support pad on a front end thereof. At least one of the internal support tube and the plurality of external support tubes is comprised of a telescoping construction. A backup frame is disposed on a rear end of the attachment system, and a crash attenuator unit is disposed on an axle and pair of wheels for mobility. When the crash attenuator is impacted by an errant vehicle, the anti-rotational attachment system is actuated to prevent the trailer mounted crash impact attenuator from rotating relative to the host vehicle.

A trailer mounted crash attenuation system has an impact head assembly, a bursting tubular trailer frame member, and a breakaway axle assembly. Upon impact by a vehicle, the head assembly is urged forward bursting the tubular frame of the trailer. As the impact continues, the head assembly contacts an axle accelerator rod which results in the disengagement of the axle, trailer tire, and fenders from the trailer frame member. Impact energy is dissipated by the controlled deceleration of the vehicle as it moves forward through the attenuator system.

A safety device is described which is configured to orient a motor-vehicle front wheel transversely to the travel direction, following a collision of the motor-vehicle against a barrier. The device includes a ram member carried by a plate projecting laterally in a cantilever fashion from the motor-vehicle structure forwardly of the front wheel. The ram member is pushed against the front wheel following a collision of the motor-vehicle against the barrier. The ram member has a vertically elongated front portion, for engaging the wheel. With the transverse plate carrying the ram member there is associated a bumper structure located forwardly of the transverse plate and including a bumper element projecting forwardly from the transverse plate, at an intermediate position between the ram member and a connected end of the transverse plate.
