An attenuation system is connected to a structural portion and includes a first portion, a second portion, and an actuator. The actuator is configured to move the attenuation system between a retracted position and an extended position. The first portion is moved outward relative to the second portion during movement of the attenuation system from the retracted position to the extended position.

The present invention discloses an active extension type car front bumper. Three fixed sleeves are rigidly connected to a cross beam of a U-shaped fixed frame, an impact rod is fitted in each fixed sleeve, a front end of each impact rod passes through the cross beam and is fixedly connected to the bumper, and a rear end of each impact rod is fixedly connected to a movable cross beam arranged horizontally left and right. Left and right longitudinal beams of the U-shaped fixed frame are each provided with a movable longitudinal beam that is movable forward and backward. Left and right ends of the movable cross beam respectively extend into the left and right longitudinal beams. A rear end of each movable longitudinal beam is fixedly connected to a hydraulic mechanism. An energy absorption mechanism is provided between every two adjacent fixed sleeves.

It is an expansion system (10) of parts (20) of a vehicle (VE) for reducing the impact resulting from a collision with another vehicle (VE′) or any obstacles, said expansion system (10) of parts (20) of a vehicle (VE) is comprised by the association of proximity/speed readers (30) with at least one electrical trigger device (40) housed in a gas release capsule (51) that has an association with at least one hermetically-sealed extension arm (50) that, once actuated, is responsible for displacing one or more components (20) that are part of the protective fairing of the vehicle (VE), such as the front (21) and/or rear (21a) bumper, door (P) plates and/or trim pieces (22), roof (T) plates and/or trim pieces, or other components that can be displaced relative to the vehicle (VE) fairing in collisions with obstacles or other vehicle(s) (VE′)

A bumper includes a carrier having a wall extending along a longitudinal axis, and a first leg and a second leg extending away from the wall in a first direction. A plurality of fins are movably attached to the carrier between the first leg and the second leg, and are spaced from each other the longitudinal axis. The fins may be moved to a deployed position to reinforce the bumper to improve low-speed damageability of the bumper, and may be moved to an inactive position, which may allow a fascia to more easily deform relative to the deployed position to provide energy absorption for pedestrian impacts.

A pedestrian safety system is disclosed herein. The pedestrian safety system includes a vehicle crossing arm system, an alarm annunciator, a plurality of sensors and an in-vehicle display device. In one embodiment, the vehicle crossing arm system may include a crossing arm and a crossing arm motor. The pedestrian safety system may be useful for improving the ability to detect movement of pedestrians in proximity to a vehicle. In particular, for detecting movement of children in proximity to a school bus.

A vehicle front end includes a bumper and a carrier attached to the bumper. A plurality of fins are movably attached to the carrier and are spaced from each other. The fins taper in a direction transverse to the bumper. The fins may be moved to a deployed position to reinforce the bumper to improve low-speed damageability of the bumper, and may be moved to an inactive position, which may allow a fascia to more easily deform relative to the deployed position to provide energy absorption for pedestrian impacts.

A vehicle includes a vehicle frame and a bumper supported by the vehicle frame. A bumper extension is supported by the bumper and is moveable downwardly relative to the bumper from a raised position to a lowered position. A reinforcement has a first end fixed relative to vehicle frame and a second end fixed relative to the bumper extension. The reinforcement includes a lock fixing the first end and the second end of the reinforcement relative to each other when the bumper extension is in the lowered position.
