Abstract: An improved automotive vehicle door hinge assembly enabling the vehicle doors to be quickly removed and reassembled during the assembly line advancement of the vehicle body. The hinge body half comprises a main member and a U-shaped extension member. The main member includes a flat mounting plate portion and a channel shaped angled portion bent outwardly from the plate portion. The U-shaped extension member has a planar base portion provided with right angled side flanges defining a pair of parallel legs each terminating in a hinge knuckle. The main member angled portion is sized for snug nested reception of the U-shaped extension member. An aperture is provided in the extension member base wall aligned with an aperture in the main member channel shaped portion bight wall. Upon tightening a threaded bolt in the aligned apertures the juxtaposed surfaces of the members are adapted for mutual clamped abutment preventing both separation and relative rotation thereof.

Abstract: A counterbalance pinion gear arrangement for a vehicle window regulator employing a guide track and flexible rack rotary-to-linear motion converter. The pinion gear is meshed with the rack and includes a spiral spring operative upon translation of the rack to rotate the pinion. The spiral spring stores energy when the window is lowered such that the spring assists in raising the window. The pinion may be used interchangeable on either side of a vehicle by providing a mirror image spring capturing cleat formed on the radial interior of the pinion rim releasably retaining a hooked end of the spiral spring. The pinion gear teeth have a blank portion to prevent inadvertent disassembly of the regulator prior to its mounting in a vehicle.
