A rear bumper structure includes a lower side member at both sides of a vehicle parallel to a length direction of a floor panel and below the floor panel, an upper side member at both sides of the vehicle parallel to the length direction of the floor panel and above the floor panel and connected to the lower side member by a rear cross member, a bracket having a first end fixed to the lower side member and a second end extending in a bent form toward the rear of the vehicle, a bumper having a first end hinge-coupled to the second end of the bracket and a second end extending in a bent form from the first end toward an outside of the vehicle, and a crash box fixed to the second end of the bumper and coupled to the upper side member.

A vehicle front structure that reduces a shock load applied to immediately under a front grille by using a bumper beam as a support. A vehicle front structure includes a shock absorbing member at an interior of a bumper face on the side near an upper portion thereof which absorbs a load from the diagonally upper front side. The shock absorbing member is at the interior of the bumper face below a front grille, and includes a load receiving portion that receives a load, a locking portion locked to an upper end edge of a bumper beam located behind and below the load receiving portion, at the time of receding of the shock absorbing member, and a connecting portion connecting the load receiving portion and the locking portion. A deformation facilitating portion with respect to a load from the upper front side is thus configured at the connecting portion.

A motor vehicle deformation device has two elements moveable together in a collision event and optionally locked. A locking device has a first centrifugal lever pivotably mounted about a first pivot axis located on the first element, a first torsion spring operatively connected to the first lever, a first rolling surface and a first contact surface arranged distally to same, as well as an identically designed second centrifugal lever neighboring the first lever. In a low-speed collision, the two levers each swivel such that the two rolling surfaces are in contact with one another and the two contact surfaces each rest against a corresponding receiving surface on the second element. In a pedestrian accident situation, the two levers each swivel such that the two rolling surfaces are in contact with one another, while the first and second contact surfaces are at a distance from the second element.

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 bumper-face support member extending in a vehicle width direction in front of a vehicle-body member provided at a vehicle-body front portion and having an attachment portion where a bumper face is attached, plural brackets fixedly connecting the vehicle-body member and the bumper-face support member, a bumper beam extending in the vehicle width direction below the bumper-face support member, and a stay connecting the bumper-face support member and the bumper beam in a vertical direction are provide. The stay has a deformation promotion portion configured to be bent so as to promote deformation of the stay when a collision load is downwardly inputted to the bumper-face support member.

There are provided a vehicle-body member provided at a vehicle-body front portion, a bumper-face support member supporting a bumper face in front of the vehicle-body member, and plural brackets fixedly connecting the vehicle-body member and the bumper-face support member. The bracket comprises an inclination portion which is inclined such that a front side thereof is positioned on an inward or outward side, in the vehicle width direction, of the bracket, a high-rigidity portion, at least part of which is positioned at the inclination portion and which is configured to have high rigidity against an input of a load applied in a vehicle longitudinal direction, and a fragile portion which is configured to be deformable by receiving the input of the load applied in the vehicle longitudinal direction. The high-rigidity portion and the fragile portion are provided adjacently to each other in the vehicle longitudinal direction.

A vehicle shock absorbing structure provided on the vehicle includes a shock absorbing member and a bracket. The shock absorbing member is disposed on a front end of the vehicle so as to extend in a vehicle width direction. The shock absorbing member includes a front end serving as a collision portion. The bracket includes a front end coupled to a rear end of the shock absorbing member. The bracket interposed between the shock absorbing member and a vehicle body. A deformation control member that extends forward and obliquely upward is provided in a coupling portion at which the bracket is coupled to the shock absorbing member. The deformation control member is more fragile than a front portion of the shock absorbing member that in front of the coupling portion and a rear portion of the bracket in rear of the coupling portion.

A pressure sensor layout structure includes: a bumper beam; an absorber disposed at a front of the bumper beam; a pressure tube arranged between the bumper beam and the absorber; a pressure sensor attached to an end of the pressure tube; and a sensor cover fixed to a rear surface of the absorber, wherein the sensor cover is fixed to an end portion in a vehicle width direction of the absorber, at two or more positions which are located variously in the vehicle width direction.

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 vehicle body front structure of a vehicle is provided. The vehicle is equipped with a bumper beam disposed on a front side of a vehicle body and extending in a vehicle width direction. The bumper beam is fixed at its lateral end portions in the vehicle width direction to the vehicle body. A guide member is disposed on each lateral end portion of the bumper beam to cover a laterally outer end surface of the bumper beam in the vehicle width direction. The guide member has a deformation allowance caused to extend in a collision in accordance with a displacement of the bumper beam.
