The shock absorber includes: a base portion fixed to the attachment target; a shock absorbing portion having flexibility and attached to the base portion so as to be reversibly switchable between a housed state in which the shock absorbing portion is retracted toward the base portion and a protruding state in which the shock absorbing portion protrudes from the base portion; and a drive unit driving the shock absorbing portion to reversibly switch between the housed state and the protruding state. The drive unit, when operating the shock absorbing portion, at least switches the shock absorbing portion from the housed state to the protruding state.

A crash impact attenuator is adapted for deployment on a vehicle, and includes a cartridge portion having at least one energy absorbing module, as well as a backup system having a backup frame, which is adapted to attach the cartridge portion to the vehicle. The backup system includes an actuator configured to pivot the cartridge portion between a deployed orientation and a stored orientation about a pivot axis disposed on a lower half of the backup system. The backup system further includes a lockout frame member having a contact surface on one end thereof, the lockout frame member being actuatable between a deployed orientation wherein the contact surface engages a portion of the backup frame to support the backup frame against vehicular impact forces and a stowed orientation wherein the contact surface is not engaged with the backup frame.

A crash impact attenuator system for deployment in front of a structure includes a rail and a plurality of diaphragms initially disposed in spaced relation along the length of the rail. Each of the plurality of diaphragms moves along the rail, so that when a front end of the crash attenuator system receives an impact force from a vehicle, a first one of the diaphragms moves rearwardly along the rail and impacts a second one of the diaphragms so that both the first and second diaphragms move further rearwardly along the rail, this process continuing with additional ones of the diaphragms until the impact forces have been fully attenuated. A tearing member on the crash attenuator system engages material forming a side or fender panel of the crash attenuator system, the tearing member tearing material forming the side panel to attenuate the impact force.

The present technology is generally directed to a magnetic repulsion system configured to reduce or mitigate the severity of an inadvertent collision between two or more vehicles. For example, the anti-collision systems disclosed herein comprise a plurality of magnetic bars carried by a vehicle. The magnetic bars have a particular polarity and, upon inadvertent contact between the vehicle and another vehicle having magnetic bars with a different polarity, the bars will repel each other, thereby inhibiting/reducing the severity of impact during an inadvertent collision between the two vehicles.

A front windshield film for vehicles is provided, which includes a windshield film and a filter film, two sides of the windshield film are provided with an installation webbing strap configured to be fixed on a target anti-roll frame, a front of the windshield film is provided with a velvet surface fixing strap, and a rear thereof is provided with a hook surface fixing strap matching the velvet surface fixing strap. The beneficial effect of the present application is that by providing the installation webbing strap on two sides of the windshield film, the windshield film is fixed on the target anti-roll frame, velvet surface fixing strap and hook surface fixing strap are provided on surfaces of the windshield film and filter film. When sunlight is too strong, a user can selectively and quickly attach the filter film to an inner side of the windshield film.
