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 a 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:
A method and apparatus for controlling deployment of pedestrian head protection devices on a motor vehicle having a metal bumper is disclosed. The disclosed inventive concept involves strategic placement of accelerometer sensing devices and the derivation of a real time impact signal from the signals generated by the accelerometers. This real time impact signal is used along with thresholds and a time window to control deployment. The apparatus includes a metal bumper, two support brackets attaching the bumper to the vehicle and at least two accelerometers fitted to the bumper proximate the brackets. The derivation and use of a single impact signal from said first and second signal-generating accelerometers is achieved by taking the larger of two absolute values derived from the accelerometers.
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:
A hinge arrangement for a bonnet of a vehicle comprises a hinge portion adapted to be attached to a body of the vehicle, a bonnet portion adapted to be attached to the bonnet, and a rear deployment guiding element adapted to control transition of the hinge arrangement between a normal position and a deployed position. The hinge portion comprises one or more hinge pivot axes providing a hinged connection between the bonnet and the body of the vehicle allowing opening of the bonnet. The bonnet portion is arranged to be in a fixed position relative to an upper portion of the hinge portion during opening of the bonnet. The bonnet portion as a whole is arranged to be translationally displaced at least upwards in relation to the upper portion of the hinge portion during a transition of the hinge arrangement between the normal position and the deployed position.
Abstract:
A pedestrian safety system for use with a motor vehicle includes a vehicle hood movable between a closed position and a raised position wherein a leading edge of the hood is raised relative to a front surface of the vehicle to form a gap, and a leg stiffener movable between a retracted position wherein it is beneath the hood when the hood is closed and a deployed position wherein the stiffener projects through the gap and is forward of the leading edge of the hood when the hood is raised. At least one actuator mounted beneath the hood moves the stiffener between the retracted and deployed positions. A remote sensing system detects an impending collision with a pedestrian and triggers the raising of the hood and extension of the actuators.
Abstract:
A pyrotechnic device contains a housing having a first end and a second end. A structural component or piston is contained within the housing. A polymer is infused into and/or about the structural component thereby accommodating the immediate ignition of the same by a known initiator/igniter in a known manner, the initiator also contained within the housing.

Abstract:
A vehicle front structure includes a cable member, one end portion of which is connected to a clutch pedal and the other end portion of which is detachably held by a retaining member arranged between an engine and a wall-like member arranged in front, in a vehicle longitudinal direction, of the engine, the cable member being arranged running across in back, in the vehicle longitudinal direction, of the wall-like member, and a protruding pressing member that is provided on a wall surface that faces a rear, in the vehicle longitudinal direction, of the wall-like member so as to face the cable member, and that detaches the other end portion of the cable member from the retaining member by pushing the cable member toward the rear in the vehicle longitudinal direction when a load is input from the front of the vehicle in the vehicle longitudinal direction.
Abstract:
A safety arrangement for a vehicle comprises a bonnet and at least one support member. In case of a collision between the vehicle and a large animal, the bonnet is supported from beneath by the at least one support member in at least a rear central portion, such that the bonnet forms a ramp for the large animal, the ramp being adapted to direct the large animal over a windscreen and/or a roof structure of the vehicle. A method of mitigating the consequences of a collision between a vehicle and a large animal may be employed in conjunction with the safety arrangement.
