Abstract

A door check including an arm with an arm mount is provided for mounting the arm to a vehicle door or frame. The arm includes a first surface and an oppositely disposed second surface. The door check further includes an arm guide including a housing, including a guide mount for mounting the housing to the vehicle door or frame, and a guideway for receiving the arm. The arm guide also includes two generally facing arm engaging structures mounted within the housing for receiving the arm therebetween. Each arm engaging structure faces its respective arm surface. The arm guide includes a spring between the housing and the second arm engaging structure. The spring biases that structure towards the first arm engaging structure to urge these structures into contact with the respective arm surfaces restricting longitudinal movement of the arm through the guideway.

Claims

1. A door check, comprising;

an arm, the arm comprising;

an arm mount provided at one end thereof for mounting the arm to one of a vehicle door or vehicle frame; and

a generally longitudinally extending first surface and an oppositely disposed longitudinally extending second surface;

an arm guide, the arm guide comprising;

a housing, the housing comprising;

a guide mount for mounting the housing to the other of the vehicle door or vehicle frame;

a guideway for receiving the arm therein; and

first and second generally facing arm engaging structures for receiving the arm there between;

the first arm engaging structure being mounted to the housing and facing the first arm surface; and

the second arm engaging structure slidably mounted within the housing and facing the second arm surface;

biasing means mounted between an inner surface of the housing and the second arm engaging structure;

the biasing means being configured to bias the second arm engaging structure towards the first arm engaging structure, to urge the arm engaging structures into contact with the respective arm surfaces and thereby restrict longitudinal movement of the arm through the guideway;

wherein the first arm engaging structure comprises a pair of slider pads, with each slider pad mounted to an opposing housing sidewall adjacent the guideway opening; and

each of the pair of slider pads comprising an arm contact surface facing and in contact with the first arm surface; and

the second arm engaging structure comprising a slider pad having an arm contact surface facing and in contact with the second arm surface.

2. A door check according to claim 1, wherein the housing comprises an open end.

3. A door check according to claim 1, wherein the vehicle frame includes at least one door pillar, and the arm mount is configured for mounting to an inner surface of the at least one door pillar of the vehicle frame and the guide mount is configured for mounting to an inner surface of the vehicle door.

4. A door check according to claim 1, wherein the arm mount is pivotally connected to the arm, and the guide mount is rigidly connected to the arm guide.

5. A door check according to claim 1, wherein the second arm surface comprises at least one position locator for locating the second arm engaging structure at a discrete position longitudinally along the arm.

6. A door check according to claim 5, wherein the second arm surface comprises at least two position locators spaced longitudinally along the arm for locating the second arm engaging structure at any one of at least two discrete positions longitudinally along the arm.

7. A door check according to claim 6, wherein the second arm engaging structure is locatable at three discrete positions longitudinally along the arm, with one of these positions corresponding to the vehicle door being closed.

8. A door check according to claim 5, wherein each position locator corresponds to a depression or detent in the second arm surface for receiving the second arm engaging structure.

9. A door check according to claim 5, wherein each position locator is defined between two proximate raised portions longitudinally spaced along the second arm surface.

10. A door check according to claim 5, wherein each position locator is at least partially defined by a friction force existing between second arm surface and the second arm engaging structure.

11. A door check according to claim 1, wherein the arm comprises an end stop for limiting longitudinal movement of the arm through the guideway.

12. A door check according to claim 1, wherein the biasing means comprises at least one of a compression spring and a rubber block.

13. A door check according to claim 1, wherein the biasing means is pre-stressed.

14. A door check according to claim 1, wherein the biasing means and the second arm engaging structure are integrated.

15. A door check according to claim 1, wherein the first surface of the arm is generally flat, and the second surface of the arm comprises three longitudinally spaced raised portions defining two locators in the form of detents between the spaced raised portions.
