Abstract:
A hood lifting mechanism includes a housing and a piston assembly movably mounted in the housing. The piston assembly has a groove formed therealong. A retainer is coupled to the housing so as to form a cavity therebetween. A locking member is positioned in the cavity so as to be engageable by the groove, for preventing motion of the piston assembly with respect to the housing.
Abstract:
The invention relates to a triggered-stroke actuator (10) comprising a body (12) housing a piston (14) and a rod (16), and a gas generator (18) mounted in said body (12) opposite said piston (14) and capable of pressurising a first chamber (20) defined between said gas generator and said piston, in which the piston (14) comprises, on its external face, a groove (30) in which is housed a sealing joint (40) with the body (12) of the actuator (10). A calibrated passage (50), adapted to evacuate gas from the first chamber (20), is formed between the sealing joint (40) and the wall of the groove (30).
Abstract:
A hood front cover assembly usable on a vehicle in which the hood has a leading edge and an underside adjacent the leading edge to reduce pedestrian injury in a pedestrian-vehicle impact event is disclosed. The cover assembly includes a deployable cover and cover housing. The housing is located on the underside of the hood adjacent the leading edge. The cover is movable between a stowed position and a deployed position. The cover may be entirely rigid or may be partially deformable and may include a hollow flexible front portion. A mechanism is provided for moving the cover between the stowed and deployed positions. The mechanism is associated with the housing and may be driven by a spring driver, a motor or a pneumatic driver. A pedestrian impact sensor is provided in the front end of the vehicle. The sensor is operatively associated with the hood front cover assembly.
Abstract:
An active hood apparatus for a vehicle may include a vehicle body bracket including a guide slot formed upwardly, an operation pin having one end configured to be inserted and slid into the guide slot and the other end connected to a hood by a link, an operation link pivotally coupled to the vehicle body bracket by a hinge pin and having one end configured for contacting the one end of the operation pin to slide the one end of the operation pin upwardly along the guide slot simultaneously with moving the operation pin in a length direction of one end at the time of being rotated, and an inflator rotating the operation link at the time of applying an operation signal thereto.
Abstract:
A latch assembly for driving a closure panel from a closed panel position to an open panel position. The latch assembly comprises: a latch mechanism having a first latch element for retaining a mating latch component in a latched position and for moving the mating latch component from the latched position to an unlatched position when released, the movement of the first latch element biased towards the unlatched position by a latch biasing element; and an actuation system having: a mechanical energy storage system having a device for storing mechanical potential energy for assisting the latch biasing element in moving the mating latch component from the latched position to the unlatched position; a mechanical advantage system having a plurality of advantage elements for engaging the device, such that movement of the plurality of advantage elements is associated with a trigger force and cooperation of the plurality of advantage elements provides for amplification of the trigger force as an initiating force to release the stored mechanical potential energy; and a trigger system configured to provide the trigger force to release the stored mechanical potential energy.
Abstract:
An active hood device for a vehicle may include a hood panel which is provided in the front of a vehicle body to cover an engine room, and rotatably mounted by a hood hinge coupled to a rear end of the hood panel, a hinge actuator which has a first side connected to the hood hinge, and a second side coupled to a bracket coupled to the vehicle body, and has a rod movable, and an operating unit which connects the bracket and the hood hinge, and allows the rod to be moved when the rod is raised, wherein at a time of a vehicle-pedestrian collision accident, the hood actuator is operated by a signal from a detecting sensor installed at a front portion of the vehicle, to raise the rod, and the rod allows the hood panel to pop up while being raised by the operating unit.
Abstract:
A pedestrian protection device for a motor vehicle, includes a front flap that is connected to a body of the motor vehicle by means of at least one coupling device and at least one adjusting device, by means of which adjusting device the front flap, by way of at least one actuator, can be moved into a protective position that is raised relative to the body of the motor vehicle and can be fixed in the protective position, wherein the at least one actuator is connected to the corresponding coupling device and to the front flap by means of a coupling joint, the coupling joint including a joint head and a joint socket unit that receives the joint head, the joint socket unit having a joint socket and a retaining element that at least partially surrounds the joint socket.
