Abstract
An automotive lift-off hinge joint to rotationally connect an automotive door and body comprises first and second door side hinge brackets and a body side hinge bracket. A detent shaft is provided with an interiorly threaded intermediate portion adapted to receive a removable threaded fastener and with a shaped detent shaft feature adapted to engage a similarly shaped pyramidal portion of a guide pin fastened to the body side hinge bracket. The detent shaft is rotationally mounted within a cylindrical check mechanism and secured in relation to the first and second door side hinge brackets. Bushings in door side hinge bracket apertures allow rotation of portions of the detent shaft extending through the apertures. The pyramidal shaped portions are preferably square.

- a first end bushing and a second end bushing located respectively adjacent the first end and the second end of the detent shaft;
- a cylindrical check mechanism with an open central core adapted to receive the first end and the intermediate portion of the detent shaft;
- said first end bushing and second end bushing being located between the detent shaft and the first and second door side hinge brackets respectively;
- the first end of the detent shaft being rotationally affixed to the first door side hinge bracket and the second end of the detent shaft being rotationally affixed to the second door side hinge bracket;
- a guide pin with a square base pyramidal shape at a central portion, a polygonal first portion, a polygonal second portion and a pin hollow core adapted to receive the removable threaded fastener;
- the first portion of the guide pin being non-rotationally affixed to the body side hinge bracket;
