A variable shear control energy absorption system for a vehicle is provided. The system may include a vehicle frame component and a primary deformable impact absorber located adjacent the vehicle frame component. The vehicle frame component may be a bumper reinforcement member. The system may include a plurality of secondary deformable impact chambers located within the primary deformable impact absorber, each secondary deformable impact chamber including a shear thickening fluid that exhibits an increasing or decreasing viscosity responsive to an impact force. At least one elastic relief chamber is provided in fluid communication with the plurality of secondary deformable impact chambers. The elastic relief chamber is configured to temporarily accept the shear thickening fluid from the plurality of secondary deformable impact chambers during low force impacts, and to redirect the shear thickening fluid back to the secondary deformable impact chambers after the low impact force recedes.

A structural component, in particular for a vehicle, includes a beam and at least one energy absorption device which is disposed on a portion of the outer surface of the beam. The beam is profiled and has at least one inner chamber.

A deformation structure has at least a first layer and a second layer, which are spaced apart from each other and displaceable relative to each other in the deformation direction or load direction. The first layer and the second layer have complementary protrusions and recesses, which are designed in such a way that the protrusions of the first layer can plunge into the recesses of the second layer and the protrusions of the second layer can plunge into the recesses of the first layer. The first layer and the second layer are connected to each other by deformable webs in such a way that, in the event of a high impulse in the deformation direction, the protrusions of the first layer plunge into the recesses of the second layer and the protrusions of the second layer plunge into the recesses of the first layer such that deformation of the deformation structure in the deformation direction occurs at a relatively low force level and, in the event of a low impulse in the deformation direction, the protrusions of the first layer hit the protrusions of the second layer such that further deformation of the deformation structure in the deformation direction occurs at a relatively high force level.

A pedestrian protection device for a motor vehicle includes a crossbar and a deformation device which is arranged in front of the crossbar. The deformation device has bending limbs with ends which contact a surface or come into contact with the surface in the event of a collision of the motor vehicle and which are designed to be movable along the surface as a result of the collision, and a latching device is formed on the surface, said latching device being latchable with the ends of the bending limbs as a result of the collision. The deformation device has a plurality of such bending limbs, wherein a first bending limb and a second bending limb are arranged adjacently to each other, and the first bending limb and the second bending limb are offset relative to each other in the movement direction of the bending limbs and/or the end of the first bending limb and the end of the second bending limb are designed to be movable in opposite directions.

A method is disclosed for manufacturing a bumper structure. A blank made out of fiber-reinforced composite material is deep drawn in a molding tool to form a bumper cross member having a first groove. A first rib structure is molded in the first groove onto the bumper cross member in the molding tool.

A bumper beam structure includes a bumper beam that extends in the vehicle-width direction and that has a closed section formed by an outer vertical wall, an inner vertical wall, a top member, and a bottom member and a reinforcing member that is mounted inside the closed section of the bumper beam at the center in the vehicle-width direction of the bumper beam. The reinforcing member has a pair of angled members that diverge in the vehicle-width direction from the outer vertical wall toward the inner vertical wall and, in a minor collision, causes an impact load to act as a tensile force on the inner vertical wall of the bumper beam through the angled members. The angled members are spot-welded to the bottom member with mounting surfaces therebetween. In a major collision, spot welding points fracture after the bumper beam collapses, thereby absorbing impact energy.

A vehicle body front structure comprises a bumper beam provided in a front portion of a vehicle body, a hood lock member provided on a rear side and an upper side of the bumper beam, and a hood lock provided on an upper side of the hood lock member and configured to engage with a hood so that the hood can be opened/closed. The hood lock member is made of a resin. A hood lock bracket made of a metal is attached to the hood lock member. The hood lock is attached to the hood lock bracket. The hood lock bracket and the bumper beam are connected by a connecting member.

A bumper unit of a vehicle includes a plurality of bumper beams arranged in a width direction of the vehicle, each of the bumper beams being coupled at both ends thereof to a vehicle body, a bumper reinforcement member configured as a molded synthetic-resin base, the base being formed with a plurality of through-holes in the width direction of the vehicle such that the bumper beams penetrate the base via the through-holes, and a strengthening band formed of reinforcement fiber tows, the strengthening band being configured to surround the exterior of the bumper reinforcement member.

A vehicle component includes a main panel extending in a first direction; a plurality of lobes extending in a second direction transverse to the first direction; and a plurality of ridges extending in the second direction. Each ridge extends around a subset of the lobes. Each lobe may be encircled by one of the ridges. The cover may include a plurality of depressions connecting the ridges to the corresponding lobes.

An energy absorbing device includes a tube. A plurality of first pellets are disposed in the tube and a plurality of second pellets are disposed in the tube. The first pellets are deformable relative to the second pellets.
