Definitions

  • the present invention relates to a hinge mechanism for connecting a bonnet to a motor vehicle that facilitates the raising of a portion of the bonnet nearest the vehicle's windscreen in the event of a collision with a pedestrian.
  • US 2006/01751 15 A1 discloses a device for reducing the impact for pedestrians wherein a bonnet lifting device has two separate airbags located near the hinges at the part of the bonnet nearest the windscreen. During their deployment the each airbag causes the associated hinge mechanism to raise the portion of the bonnet nearest the windscreen. The hinge mechanism allows the bonnet to be raised at the front of the vehicle during normal use. When the airbag is deployed it causes a pin to move towards the front of the vehicle in a guide slot, this causes a pivot point of the hinge to move forwards causing the arms of the hinge to raise the rear portion of the bonnet giving the airbags an opening to deploy over the windscreen. That is to say a pivot point of the articulated hinge is moved when the airbag is deployed resulting in the lifting of the rear section of the bonnet.
  • US 2008/0093150 A1 discloses a pedestrian protection bonnet lifting system wherein a device that causes the rearward portion of a bonnet to be raised has a spring that is under load, the load is released by a mechanism that releases the load, for example by retracting a stop, the spring then causes a piston to move.
  • the moving piston forces air into an inflatable body that causes the bonnet to be raised.
  • the piston causes an articulated hinge to move and raise the bonnet.
  • one end of a leaf spring is attached to the piston and when tension of the coil spring is released the other end of the leaf spring causes the bonnet to be raised.
  • a claimed advantage of this device is that it can be readily reset if the bonnet is raised without interacting with a pedestrian.
  • US 2009/0288271 A1 discloses an over center sprung bonnet hinge for use with an active pedestrian protection system wherein two arms of a hinge are joined together by a pivot.
  • An over center spring has one end of the spring attached to each of the hinge arms.
  • an actuator causes a piston to move upward and push on the upper of the two hinge arms
  • the upper hinge arm engages a bottom surface of the vehicle's hood.
  • the over center spring limits the travel of the upper hinge arm.
  • a pin extending through a slot in the lower hinge arm also aids in limiting the travel of the upper hinge arm. While the vehicle hood may be manually pushed back into place after the deployment device has been activated, the device will not operate properly again until after it has been serviced.
  • US 2009/0289473 A1 discloses a key cam system for hinge with active pedestrian protection system wherein two arms of a hinge are joined together by a pivot.
  • a cam mechanism locks the hinge in a closed position.
  • an actuator causes a piston to move upward and push on the upper of the two hinge arms a shear pin is broken by the movement of the piston.
  • a cam moves along a cam path in the cam mechanism to limit the upward movement of the upper hinge arm and the vehicle hood. While the vehicle hood may be manually pushed back into place after the deployment device has been activated, the device will not operate properly again until after it has been serviced.
  • EP 2351671 A1 discloses a hinge mechanism for connection of a vehicle bonnet to the vehicle wherein a hinge has an upper hinge wing with upper and lower parts that are articulately connected with each other. A relative motion of the upper part takes place in relation to the lower part from a normal position into a crash position after separation of a connection fixing the upper part with the lower part by a separating mechanism.
  • the upper part lies in a normal position over a stopper element against a limiting element of the lower part.
  • a contact surface extends parallel to an adjustment direction of the upper part in relation to the lower part.
  • the stopper and limiting element may have a plastic coating.
  • WO 2009/01 1731 A1 discloses a pedestrian protection airbag system wherein a mechanical device functions as both a hinge allowing the bonnet to be raised at the front of a vehicle and as a release allowing a region of the hood closest to the
  • JP 2004-322724 discloses a device for protecting a pedestrian wherein when an airbag is deployed, the length in a vehicular width direction is shortened.
  • a lock pin is pulled out from a hole in the hinge mechanism by a wire, thereby releasing locking of a hinge mechanism.
  • This device is undesirable because the lock pin can become jammed in the locking hole such that both movement mechanisms namely the lifting of the hood by the airbag and the removal of the lock pin from the locking hole block each other.
