A bumper assembly includes a beam and a plurality of members attached to and positioned sequentially along the beam. Each member includes an outer tube extending transverse to the beam and an inner tube extending parallel to and in the outer tube. Adjacent ones of the members are configured to contact each other when both adjacent ones of the members are deformed.

A vehicle bumper includes: a bumper beam, a bumper face, covering a vehicle body front surface of the bumper beam, and a buffer component, provided between the bumper beam and the bumper face. The buffer component includes a platelike component configured to be folded upon collision load. The buffer component includes a folded part, and two surface parts that are connected through the folded part and are opposite to each other with a gap therebetween in a front-rear direction of the vehicle. A pressure pipe configured to be deformed by being clamped between the two surface parts so as to detect impact is provided in the gap. A lower space part that avoids interference between the bumper beam and a setting part for the pressure pipe in the buffer component is provided below the bumper beam.

An arrangement for absorbing kinetic energy acting on a front bumper of a vehicle, in particular a motor vehicle, includes at least one pedestrian protection element which can be arranged on a cross member of the bumper, at least one absorption element which can be arranged on the cross member and is movable on the cross member in the longitudinal direction of the vehicle relative to the cross member between a front absorption position and a rear release position, and at least one locking device which can be arranged on the cross member by which the absorption element can be temporarily arrested in the absorption position thereof. The absorption element, in the absorption position thereof, is switched parallel to the pedestrian protection element in respect of a force initiated by the kinetic energy into the bumper.

A pedestrian protection device for a motor vehicle includes a bumper crossmember and a deformation element which is arranged on the bumper crossmember and which has a first element and a second element which are displaceable relative to each other in the event of a collision of the motor vehicle, and a mechanical locking mechanism. The locking mechanism has a movable locking element which is pretensionable or is pretensioned with a spring device and which is arranged on the first element or on the second element, and with a depression or step to which the other of the first element and the second element can be latched in a form-fitting manner. In the event of a high displacement speed which is greater than or equal to a predetermined second displacement speed, the locking mechanism prevents displacement of the first element relative to the second element by means of self-locking of the locking element. In the event of an average displacement speed which is lower than the predetermined second displacement speed and greater than a predetermined first displacement speed, the locking mechanism permits displacement of the first element and of the second element relative to each other.

A pedestrian protection device for a motor vehicle, in particular for a front part of the motor vehicle, includes a bumper crossbeam and a deformation element arranged in front of the bumper crossbeam. The deformation element has a bending section, the end of which is in contact with a surface or which comes into contact with the surface in the event of a collision, in particular a front collision of the motor vehicle. The end of the bending section is designed such that it can move along the surface as a result of the collision, wherein the surface has an engaging device with which the end of the bending section can be, in particular, engaged.

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 front end structure is disclosed for a vehicle to enhance vehicle compatibility performance. The front end structure includes a bumper disposed behind a front fascia panel. Crush cans are attached between the bumper and a frame rail. A shield is attached to the bumper that extends above the bumper and below the bumper to spread deformation caused by the crush cans and bumper of a deformable barrier in a collision to areas above and below the bumper.

A pedestrian protection apparatus for a motor vehicle front end has a leg-contacting segment which, in a pre-impact position, is arranged completely above an approach plane of the vehicle (which is defined by way of a front approach angle of the motor vehicle), and can be adjusted into a post-impact position by means of a force deflecting apparatus by way of at least proportionally vertical deflection of an impact force which acts along the longitudinal direction. In a post-impact position, the contact segment is arranged at least partially below the approach plane and lower than a bumper crossmember.

A method for making a crush can for a vehicle which has an internal moulded structure can include providing a crush can with a hole, filling the hole in the crush can with a fibre-reinforced material and compression moulding the fibre-reinforced material using the internal shape of the crush can as an outer shell of a split mould.

A bumper arrangement (1) for a motor vehicle, in particular for a lower load plane, wherein the bumper arrangement (1) has a bumper crossmember (2) and two spaced-apart supporting profiles (3, 3), the first ends (4, 4) of which are each fastened indirectly or directly to one of the two regions of the bumper crossmember (2) that are in the vicinity of the end and which are each fastened at a second end (5, 5) to chassis parts or longitudinal member parts (6) formed on the motor vehicle, wherein the bumper crossmember (2) is held by the supporting profiles (3, 3) on the vehicle structure and has a preferably symmetrically curved portion (7) in the form of a portion of a tube or a portion of a groove or a portion of a profile, wherein the portion (7) is fastened by its ends (8, 8) in the vicinity of the second ends (5, 5) of the supporting profiles (3, 3) to the chassis parts or longitudinal member parts (6), wherein the curved portion (7) is shaped in a manner projecting with a central region (9) to the bumper crossmember (2) and therefore at least lies against the bumper crossmember (2).
