Abstract
An actuation system for facilitating opening and closing of a closure panel of a vehicle via a hinge, the actuation system comprising: a pop up safety system mounted to a body of the vehicle adjacent to the hinge, the pop up safety system including a bracket connected to the closure panel; and a coupling mechanism coupling the hinge to the body in order to facilitate moving the closure panel from a closed hinge position to an open hinge position, such that the bracket is also connected to the coupling mechanism; wherein when the pop up safety system is operated, the bracket is decoupled from the coupling mechanism in order to facilitate movement of the closure panel away from the coupling mechanism.
Claims18
An actuation system (9) for facilitating opening and closing of a closure panel (13) of a vehicle (11), the actuation system comprising:
- a hinge (12) coupled to a body of the vehicle and to the closure panel, the hinge having a normal mode for moving the closure panel to an open position and an active pedestrian protection mode for moving the closure panel to an active pedestrian protection position;
- a first actuator (16) for actuating the hinge to move the closure panel to the open position in the normal mode;
- a second actuator (300) for actuating the hinge to move the closure panel to an active pedestrian position in the active pedestrian protection mode;
- and
- a counterbalance (308) adapted to assist with moving the closure panel;
- wherein the counterbalance is adapted to assist with moving the B closure panel during both the normal mode and the active pedestrian mode;
- wherein
- the first actuator comprises an electric motor and the second actuator comprises a pyrotechnic device;
- wherein
- the first actuator further comprises gearing actuated by the electric motor during the normal mode, wherein the gearing is not actuated by the electric motor during the active pedestrian protection mode.
An actuation system for facilitating opening and closing of a closure panel (13) of a vehicle (11), the actuation system comprising:
- a hinge (12) coupled to a body of the vehicle and to a rear of the closure panel, the hinge having a normal mode and an active pedestrian protection mode;
- a striker assembly (130) coupled to the front of the closure panel, the striker assembly having a striker bracket having a striker mounted thereon, and a closure panel striker bracket connected to the closure panel;
- a first actuator (300) for moving the rear of the closure panel from a closed position to an active pedestrian position in the active pedestrian protection mode;
- and
- a second actuator (16b) adapted to move the front of the closure panel from a closed position to an active pedestrian position;
- wherein the closure panel striker bracket (13y) is adapted to move relative to the striker bracket (13x) during the second actuator moving the front of the closure panel to the active pedestrian position;
- wherein
- the first actuator comprises an electric motor and the second actuator comprises a pyrotechnic device;
- wherein
- the first actuator further comprises gearing actuated by the electric motor during the normal mode, wherein the gearing is not actuated by the electric motor during the active pedestrian protection mode.
A method (1500) for operating the opening and closing of a closure panel of a vehicle via a hinge, the method comprising:
- using a first actuator adapted to move the closure panel between a closed position and an open position (1502);
- using a second actuator adapted to move the closure panel from the closed position to an active pedestrian position (1504);
- using a third actuator adapted to move the closure panel from the closed position to both the open position and the active pedestrian position (1506);
- wherein
- the first actuator comprises an electric motor and the second actuator comprises a pyrotechnic device;
- wherein
- the first actuator further comprises gearing actuated by the electric motor during the normal mode, wherein the gearing is not actuated by the electric motor during the active pedestrian protection mode.
