Door check for vehicle sliding door
First Claim
1. A door check arrangement for a sliding door of a vehicle comprising:
- an arm generally fixably connected with the door, along a first end of the arm, and the arm being generally translationally connected with the vehicle along a second end of the arm, the arm adjacent the second end having an elongated aperture with first and second ends;
a track mounted with the vehicle for receiving the second end of the arm, the track having a striker plate and an entrapment section;
a rotary detent plate pivotally and slidably mounted in the elongated aperture of the arm, the detent plate having first and second arms and the detent plate also having a locking member;
a spring for biasing rotation of the detent plate in a first angular direction and for translationally biasing the detent plate toward the first end of the elongated aperture;
a contact surface fixed upon the arm, the fixed contact surface interacting with the second arm of the detent plate whereby motion of the door from a closed position to a checked open position causes the detent plate locking member to contact the striker and to pivot the detent plate in a second angular direction opposite the first angular direction and to move the detent plate toward the second end of the elongated aperture and wherein further movement of the door toward a checked open position causes the detent plate to pivot again in the first angular direction to place the locking member 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 direction of the elongated aperture 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 locking member to contact the striker and for the detent plate second arm to have relative motion with the fixed contact surface, thereby causing the detent plate to rotate in the second angular direction and causing the detent plate locking member to pivot out of the entrapment section and for the detent plate to translate toward the second end of the elongated aperture to allow the detent locking member to release the door from the checked position.

Abstract
A vehicle door check is provided including an arm connected with the door along a first end and with the vehicle along a second end, the arm adjacent the second end having a slot with first and second ends; a track of the vehicle for receiving the arm second end having a striker plate and an entrapment section; a rotary detent plate slidably mounted in the arm slot having its own first and second arms and a locking member; a spring for biasing rotation of the detent plate in a first angular direction and toward the slot first end; a contact surface fixed upon the arm interacting with the detent plate second arm whereby motion of the door from a closed position to a checked open position causes the detent plate locking member to contact the striker and pivot the detent plate in a second angular direction opposite the first angular direction and to move the detent plate toward the slot second end and wherein further movement of the door toward a checked open position causes the detent plate to pivot again in the first angular direction to place the locking member in the track entrapment section of the track with a low 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 slot.

11. A door check arrangement for a sliding door of a van-type vehicle comprising:
-
an arm generally fixably connected with the door along a first end of the arm and the arm being generally translationally connected with the vehicle along a second end, the arm adjacent its second end having a generally straight elongated aperture with a first end and a second end; a track mounted with the vehicle for receiving the second end of the arm, the track having a striker plate, the striker plate being inclined between 28 and 32 degrees, and an entrapment section; a rotary detent plate pivotally and slidably mounted in the elongated aperture, the detent plate having a first arm and a second curvilinear arm and the detent plate also having a downwardly extending locking member; a coil spring engaged with the rotary detent plate first arm for biasing rotation of the detent plate in a first angular direction and biasing the detent plate translationally toward the first end of the arm elongated aperture; a fixed contact surface connected with the arm and contacting the second arm of the detent plate, whereby motion of the door from a closed position to a checked open position causes the detent plate locking member to contact the striker inclined surface, causing the detent plate to pivot against the biasing of the spring and to move the detent plate toward the second end of the elongated aperture and whereupon further opening movement of the door causes the detent plate to pivot in the first direction to place the locking member in the entrapment section of the track when the door is imparted with a low first threshold of force, and wherein the door is checked open even when the vehicle is on an incline, and wherein pulling the door closed from the checked position under a second force significantly higher than the first force causes the detent plate locking member to contact the striker and the detent plate second arm to contact with the fixed contact surface, causing the detent plate locking member to pivot out of the entrapment section in a second angular direction and for the detent plate to translate toward the second end of the elongated aperture to allow the detent locking member to release the door from the checked position.
