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.

A motor vehicle includes two hinge joints to swingably connect a front gate to the vehicle body. Each hinge joint includes a body-side hinge lower part and a gate-side hinge upper part that includes an upper part portion swingably arranged on another upper part portion, with the upper part portions being detachably secured by a locking member. Pivot struts swingably connect the hinge lower and upper parts to one another, with one pivot strut including a strut portion arranged on an upper part portion and movable translatorily in relation to another strut portion. To raise the front gate for protection, an actuator is activated to thereby release the locking member and pivot one upper part portion relative to the other one upper part portion, thereby translatorily moving one strut portion relative to the other strut portion, and with the one upper part portion pivoting relative to the other pivot strut.

An actuator includes a housing section that houses a driving source and is mountable on a first mounting region and a deploying section that is mountable on a second mounting region and deployable with a driving force of the driving source. The housing section includes a case of metal and a securing member supporting the driving source and secured to the case inside the case. A mounting hole is formed through the case and securing member for receiving a pivot member connected to the first mounting region. A fixing hole is formed through the case and the securing member at a different position from the mounting hole for receiving a fixing member that fixes the securing member to the case. An inner circumferential plane of the mounting hole of the case is in contact with the pivot member on the region disposed towards a deploying direction of the deploying section.

A motor vehicle includes a hinge mechanism supporting a hood and an airbag configured to deploy close to or into the exterior of the motor vehicle for protecting pedestrians. The hinge mechanism is operably for positioning the hood in a normal closed position to close off an engine compartment and a normal open position providing access to the engine compartment for servicing work. The hinge mechanism has a breakable connecting element for connecting a first part and a second part of the hinge mechanism. In the event of an accident the connecting element is broken, so that a rear end area of the hood is movable from the normal closed position into an accident position which is partly open in the area of the front windscreen. The second part is supported by a mechanism such that the hood is movable relative to the body.

A cyclist protection apparatus for a vehicle includes including a front section that protrudes forward from a boarding section and includes an upper surface formed by a hood. The cyclist protection apparatus includes a hood latch and a cyclist airbag device. The hood latch is capable of releasing a closed state of the hood such that a front of the hood is openable. The cyclist airbag device is configured to be disposed in the front section below the hood and deploy a cyclist airbag. The cyclist airbag device is configured to deploy the cyclist airbag forward from below the hood in either one of a state where the front of the hood is open and a state where the front of the hood is openable.

Please substitute the new Abstract submitted herewith for the original Abstract: A hinge system of a hood of a vehicle has a hinge which is arranged between the hood and a mating element of the vehicle. The hinge is designed both for opening the hood and for raising the hood when the latter is in the closed state, and includes a lifting-piston actuator for initiating a raising movement of the hood. The lifting-piston actuator has a piston element which can be connected to the hinge and/or the hood in a form-fitting manner in order to limit freedom of movement of the hood.
