Abstract: A check strap assembly particularly for use with a passenger door of a motor vehicle includes an arm having a first end interconnected to the body of the vehicle and a second end interconnected to the vehicle door. The check strap assembly further includes a locating mechanism disposed within the door and attached to a forward panel of the door. The arm extends through an aperture located in the forward panel of the door and is translatable relative to the locating mechanism and the door. A seal member is provided which is operative to seal the aperture and the panel of the door. The seal member is carried by the arm such that the seal member abuts the panel of the door when the door is in the closed position and is spaced from the panel of the door when the door is in the fully opened position. The seal operates to protect the cooperating components of the check strap assembly from dirt, moisture and other contaminants when the vehicle door is in its closed position.
