Push/pull handle operating system for a motor vehicle door
An operating system for a motor vehicle door includes a handle that is displaceable between a latching position, a first unlatching position and a second unlatching position. The operating system also includes a latch mechanism including a latch and a cooperating receiver. The operating system further includes a mechanical connection feature connecting the handle to the latch whereby the motor vehicle door may be unlatched by displacing the handle.
1. An operating system of a motor vehicle door, comprising:
a handle displaceable between a latching position, a first unlatching position and a second unlatching position;
a latch mechanism including a latch and a cooperating receiver; and
a mechanical connection feature connecting said handle to said latch whereby said motor vehicle door is unlatched by displacing said handle.
2. The operating system of claim 1 , wherein said handle includes a first pivot, a first cam surface and a first biasing element biasing the handle toward said latching position.
3. The operating system of claim 2 , wherein said mechanical connection feature includes a mechanical cam having a second cam surface engaging said first cam surface, said mechanical cam being displaceable between a first position and a second position.
4. The operating system of claim 3 , wherein said mechanical cam includes a second pivot and a second biasing element biasing said mechanical cam toward said second position.
5. The operating system of claim 4 , wherein said mechanical connection feature includes a link having a first end connected to said mechanical cam and a second end connected to said latch.
6. The operating system of claim 5 , wherein said latch includes a third pivot and is displaceable between a door latching position in engagement with said receiver and a door unlatching position disengaged from said cooperating receiver.
7. The operating system of claim 6 , further including an actuator to swing said motor vehicle door open when said latch is in said unlatching position.
8. A motor vehicle, comprising:
a chassis;
a door carried on said chassis and displaceable between a closed position and an opened position; and
an operating system for said door including (a) a handle displaceable between a latching position, a first unlatching position and a second unlatching position, (b) a latch mechanism including a latch and a cooperating receiver and (c) a mechanical connection feature connecting said handle to said latch whereby said door is unlatched by displacing the handle.
9. The motor vehicle of claim 8 , wherein said handle, said latch and said mechanical connection feature are carried on said door and said cooperating receiver is carried on said chassis.
10. The motor vehicle of claim 9 , wherein said handle includes a first pivot, a first cam surface and a first biasing element biasing the handle toward said latching position.
11. The motor vehicle of claim 10 , wherein said mechanical connection feature includes a mechanical cam having a second cam surface engaging said first cam surface, said mechanical cam being displaceable between a first position and a second position.
12. The motor vehicle of claim 11 , wherein said mechanical cam includes a second pivot and a second biasing element biasing said mechanical cam toward said second position.
13. The motor vehicle of claim 12 , wherein said mechanical connection feature includes a link having a first end connected to said mechanical cam and a second end connected to said latch.
14. The motor vehicle of claim 13 , wherein said latch includes a third pivot and is displaceable between a door latching position in engagement with said receiver and a door unlatching position disengaged from said cooperating receiver.
15. The motor vehicle of claim 14 , further including an actuator to swing said door open when said latch is in said unlatching position.
16. The motor vehicle of claim 8 , wherein said latching position is between said first unlatching position and said second unlatching position.
17. The motor vehicle of claim 16 , wherein said handle passes through a support carried on said door.
18. A method of unlatching a motor vehicle door including a pivoting handle, comprising:
pivoting said pivoting handle from a latching position either in a first direction to a first unlatching position or in a second direction to a second unlatching position; and
unlatching a latch for said motor vehicle door via a mechanical connection feature.
19. The method of claim 18 , including pushing or pulling on said pivoting handle to unlatch said motor vehicle door.
20. The method of claim 19 , including opening said motor vehicle door when unlatched by an automatic door opening feature.
