A number of variations may include a product comprising an airbag mounted in a fender region laterally adjacent a hood and forward of a vehicle side door which provides a means for deployment through a discrete door to provide protection to a pedestrian from impacting the frontal area of a vehicle structure.

A vehicular pedestrian protecting airbag device that is capable of suppressing increases in weight and cost accompanying reinforcement measures, and capable of maintaining good pedestrian protection performance of an upper face of a hood. An automobile pedestrian protecting airbag device is installed at a vehicle lower side of a rear end section of a hood at a vehicle rear side of a protruded portion. A pedestrian protecting airbag and an inflator are installed inside a module case. The inflator is attached to a bottom wall of the protruded portion by inflator attachment brackets each formed with an excess length portion at an intermediate portion. Accordingly, when the inflators attempt to move toward the vehicle front side due to deployment reaction force of the pedestrian protecting airbag, the excess length portions are compressed and deform to enable the deployment reaction force to escape.

Disclosed are impact sensor arrangements for active hood systems, methods for making and for using such impact sensor arrangements, and motor vehicles with active hood systems using such impact sensor arrangements. Disclosed, for example, is an impact sensor arrangement for an active hood system of a motor vehicle. An active hood system actuator is selectively actuable to displace the vehicle's engine hood. The impact sensor arrangement includes a sensor connected to a sensing tube to detect a characteristic change of the sensing tube and responsively output an actuator trigger signal. First and second blocks, each formed from a high-density material, attach to the vehicle body adjacent the bumper and collectively define an internal channel within which is nested the sensing tube. The first block is movably attached to the second block such that displacement of one block with respect to the other initiates the characteristic change of the sensing tube.

A hood back portion moving mechanism is supported with a hinge on a side of a vehicle body such that a back end portion of a hood provided at a front portion of a vehicle body is able to be opened and closed, and the hood is lifted up by an actuator. A back end portion of a pop-up link is rotatably coupled to an upper hinge included in the hinge, the hood is rotatably coupled to a front end portion of the pop-up link, and the actuator is bridged over the upper hinge and the hood.

A hood lifter assembly includes an actuator having a piston displaceable between a home position and a hood lifting position. The hood lifter assembly also includes a cover overlying the piston in the home position and protecting the actuator from water exposure. A cowl vent grille and a method of lifting a vehicle hood in response to a pedestrian impact event are also disclosed.

A novel actuator contains a housing having a first end, a second end, and an inner wall. A piston rod assembly is contained within the housing, wherein the assembly contains a piston rod, a first end cap fixed at one end of the piston rod, and a second end cap fixed at an opposing end of the piston rod. An energy management device is constrained about an outer diameter of the first end cap, wherein upon actuation of the actuator, the energy management device may under predetermined conditions be deformed upon movement of said piston rod.
