Abstract:
A pivoting door mechanism in a motor car having a body with a door frame which includes a forward door post, a door, first and second support arms, each support arm having a proximal end and a distal end, first and second body hinges mounted on the door frame at respective positions which are vertically spaced-apart a given distance, the first and second body hinges being mounted on the respective proximal ends of the first and second support arms for relative pivotal movement about respective first and second inboard pivot axes, first and second door hinges mounted on the door at respective positions which are vertically spaced-apart a distance which is substantially equal to the given distance, the first and second door hinges being mounted on the respective distal ends of the first and second support arms for relative pivotal movement about respective first and second outboard pivot axes, and the inboard and outboard pivot axes are parallel and each axis extends normal to a longitudinal mean plane of the car, each axis also extending in a direction which forms substantially the same acute angle .alpha. with a horizontal plane, the door mechanism being characterized in that the body hinges are mounted on the forward door post, the inboard and outboard pivot axes are positioned to lie in a common plane which is normal to the longitudinal axis, the mechanism further comprises a stability lever having first and second ends which are mounted for articulated relative movement on the respective first and second support arms at respective first and second points of articulation, the first and second points of articulation being located along a first axis which is parallel to a second axis that extends between the door hinges whereby the support arms guide the door for stable movement between open and closed positions relative to the door frame as the support arms undergo said relative pivotal movement with respect to the inboard and outboard pivot axes.
