An airbag system includes a bag unit which deploys on an enginehood of a vehicle body by a gas from an inflator. The bag unit is divided into bags back and forth and right and left. The bags include adjacent bags communicating with each other through communication paths. The bags include at least one upright bag to be upright on at least one fender of left and right fenders of the vehicle body. A gas flows from a front bag of the bags located at a front side of the vehicle body through communication paths to a rear bag of the bags behind the front bag and the at least one upright bag on the side of the front bag.

Embodiments of safety trucks incorporate multiple connection points to which a variety of attachments, or combinations of attachments, can be releasably and interchangeably coupled to enable their use with increased effectiveness to safeguard roadway construction, maintenance and repair personnel as they perform tasks within or relatively near to roadway workzones and worksites. Also, methods of operation of the safety truck embodiments enhance their ability to guard and protect roadway construction, maintenance and repair personnel while they work within or relatively near to roadway workzone and worksite locations.

An increased amount of absorption of a load from the diagonally upper front side is achieved even in, for example, a vehicle having a high vehicle height. A first shock absorbing member is provided inside a bumper face upper to absorb a load from the diagonally upper front side, a second shock absorbing member is mounted on a front face portion of a bumper beam, and a third shock absorbing member is disposed below the first shock absorbing member and between a bumper face and the bumper beam to absorb a load from the diagonally upper front side. The rigidity of the first and third shock absorbing members in the up-down direction is higher than rigidity of the second shock absorbing member in the front-rear direction.

A vehicle front structure that absorbs a shock load applied to immediately under a front grille by using a structure at a position higher than a bumper beam as a support. The vehicle front structure includes a shock absorbing member at an interior of a bumper face below a front grille. The shock absorbing member includes a load receiving portion that receives a load, an abutting portion abutting against a structure above a bumper beam during receding of the shock absorbing member, an upper-side connecting portion connecting the load receiving portion and the abutting portion, a locking portion deformed while being locked to the bumper beam during receding of the shock absorbing member, and a lower-side connecting portion connecting the load receiving and locking portions. A bending facilitating portion extending in the vehicle width direction is formed on the side of a rear portion of the upper-side connecting portion.

Apparatuses, systems, and methods for absorbing energy in a hinge are provided. An apparatus may include a first portion, a second portion coupled to the first portion to move relative to the first portion, and a tab configured relative to the first and second portions to absorb energy imparted to the second portion during a collision. The tab may be bendable via rotation as the second portion moves towards the first portion during the collision. The first portion may be a hinge bracket securable to a vehicle body. The second portion may be a hinge arm securable to a vehicle hood. The tab may be positioned at least partially between the first portion and the second portion for selective interference of the tab with one of the first portion and the second portion.

A duct 20 includes: wall portions 24, each of which defines a corresponding one face of an air flow path 22 leading air from an air inlet 20a to an air outlet 20b; and groove portions 26, which are provided on at least two of the wall portions 24, 24, respectively, and extend so as to cross an air flow direction of the air flow path 22, and the groove portions 26 are independent from each other for every wall portion 24, and have a concave shape so as to thin the wall portions 24.

An extension of a grille extends rearward and in a left-right direction of a vehicle. The extension is located rearward from a grille body and below a ventilation hole. An extension rear edge is arranged above a structure front upper edge. An extension front edge at which the grille body and the extension are connected to each other is arranged below the structure front upper edge. The extension is inclined from the extension front edge toward the extension rear edge. The extension includes weak portions that divide the extension into a plurality of sections in the left-right direction.

A deformation structure includes at least one first layer and a second layer, which are arranged spaced apart from one another in a deformation direction and such that they can be displaced relative to one another. 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 and recesses of the second layer, as well as the protrusions of the second layer and recesses of the first layer can dip into one another. The first layer and the second layer are connected to one another via deformable web elements in such a way that, with a high impulse in the deformation direction, the protrusions of the first layer dip into recesses of the second layer, and protrusions of the second layer dip into recesses of the first layer, such that a deformation of the deformation structure occurs at a low force level in the deformation direction, and with a low impulse in the deformation direction, the protrusions of the first layer impinge on the protrusions of the second layer such that a deformation of the deformation structure occurs at a high force level in the deformation direction.

A bumper arrangement of a passenger car has an upper and a lower load path. A spring element is provided on the transverse support of the lower load path, which, in the event of a collision of a pedestrian with the passenger car, exerts an additional force on the lower leg of the pedestrian, so as to support the movement of the pedestrian in the direction of the front hood of the passenger car.

An energy absorber for interposition between a cover and a covered object includes a generally planar matrix of cells. Each of the cells includes a plurality of generally elongate micro-elements interconnected to form a cell micro-structure, with each cell having a respective energy absorption capacity such that an energy absorption capacity of the energy absorber varies across at least one direction. The cells are configured such that impulse of an object with the cover with the energy absorber sandwiched between the cover and the covered object causes a deceleration vs. time response in the object, beginning with a generally linear rise in the deceleration to a peak deceleration within 5 ms after the beginning of the impulse event, followed by a generally nonlinear decrease in the deceleration over a period of not greater than 15 ms to a final target deceleration of not greater than 10% of the peak deceleration.
