1. A door check arrangement for a sliding door of a vehicle comprising:

  • an arm generally fixably connected to the door along a first end of the arm, and the arm being generally translationally connected to the vehicle along a second end of the arm;

    a track mounted within the vehicle for receiving the second end of the arm, the track having a striker plate and an entrapment section;

    a support connected to the arm generally adjacent the second end of the arm, the support having a first slot with first and second ends and a second slot having first and second surfaces angled from one another;

    a detent plate having a surface inclined with respect to the striker plate, the detent plate also having first and second pivot pins mounted within the first and second slots;

    spring means biasing the detent plate to place the first pivot pin toward the first slot first end and the second pivot pin on the first surface of the second slot, whereby motion of the door from a closed position to a checked open position causes the detent plate inclined surface to contact the striker and to pivot the detent plate in a first angular direction and wherein further movement of the door toward a checked open position causes the detent plate to pivot again in a second angular direction opposite the first angular direction to place the detent plate in the entrapment section of the track with a low first threshold of force on the door in the opening direction and wherein the door is thereafter checked open even when the vehicle is on a declining surface toward the first end of the first slot, and wherein pulling the door closed from the open checked position with a second force on the door significantly higher than the first opening force causes the detent plate to contact the striker and the first pivot pin to move toward the first slot second end and for the second pivot pin to move from the second slot first surface to the second slot second surface, thereby causing the detent plate to pivot in the first angular direction and causing the detent plate to pivot out of the entrapment section to allow the detent plate to release the door from the checked position.
