    Abstract: A door is pivotally mounted to a vehicle by an infinite position hold open hinge including conventional male and female hinge members pivotally interconnected. The female hinge member pivotally mounts one end of a lever about an axis inboard from the hinge axis with the other end of the lever having a depending flange with a center arcuate surface generated about and facing away from the hinge axis. The male hinge member mounts a plastic brake having an arcuate surface generated about and facing the hinge axis for engagement with the arcuate surface of the lever. A spring extending between the female hinge member and the other end of the lever biases the arcuate surface of the lever into frictional engagement with the arcuate surface of the brake. The depending flange also has lead in surfaces providing a smooth transition to the center arcuate surface the female hinge member includes and a stop preventing engagement of the lever the and brake when the door is in closed position to prevent the brake from taking a permanent set. Moving the door from closed position to open position moves the arcuate surface of the lever along the arcuate surface of the brake to produce a frictional drag which wedges the surfaces apart against the action of the spring to decrease the effort of opening the door. Moving the door from open position to closed position moves the arcuate surface of the lever oppositely along the arcuate surface of the brake to produce a frictional drag which wedges the surfaces together aiding the action of the spring to increase the effort of closing the door. When the door is in an intermediate position between the open and closed positions, the engagement between the arcuate surfaces of the lever and brake prevents movement of the door toward either the open or closed positions until a predetermined force is applied to the door.

    Abstract translation: 门通过无限位置保持开启铰链枢转地安装到车辆，包括枢转地互连的常规公和铰链构件。 阴铰链构件将杠杆的一端围绕铰链轴线内侧的轴线枢转地安装，杆的另一端具有垂直凸缘，其中心弓形表面围绕并背离铰链轴线产生。 阳铰链构件安装塑料制动器，其具有围绕并面对铰链轴线产生的弓形表面，用于与杆的弓形表面接合。 在所述阴铰链构件和所述杆的另一端之间延伸的弹簧将所述杆的弓形表面偏压与所述制动器的弓形表面摩擦接合。 悬垂的凸缘还在表面提供平滑过渡到中间的弧形表面，并且当门处于关闭位置时防止接杆和制动器的接合，以防止制动器采取永久变形。 将门从关闭位置移动到打开位置沿着制动器的弓形表面移动杠杆的弓形表面以产生摩擦阻力，该摩擦阻力克服弹簧的作用楔入表面，以减小打开门的力度。 将门从打开位置移动到关闭位置使杆的弓形表面沿着制动器的弓形表面相反地移动，以产生摩擦阻力，该摩擦阻力将表面楔入一起辅助弹簧的作用以增加关闭门的力度。 当门处于打开位置和关闭位置之间的中间位置时，杠杆和制动器的弧形表面之间的接合防止门向打开或关闭位置移动，直到预定的力施加到门。
