Abstract

This disclosure relates to a motor vehicle having a door check mechanism. An example motor vehicle a pivotable door, a door check mechanism including a bar, wherein the door check mechanism is configured to hold the door open in a fully open check position, and a retarder assembly configured to oppose opening of the door beyond the fully open check position by applying a force generated by a non-linear surface of the bar.

First claim

The invention claimed is:

1. A motor vehicle, comprising:
a pivotable door;
a door check mechanism including a bar, wherein the door check mechanism is configured to hold the door open in a fully open check position; and
a retarder assembly configured to oppose opening of the door beyond the fully open check position by applying a retarding force to the door, wherein the retarding force is generated by interaction between the retarder assembly and a non-linear surface of the bar,
wherein the bar is attached at a first end to a body of the motor vehicle and is attached to the door via a support housing,
wherein the support housing abuts a compressible member, wherein the retarding force includes a reaction force produced by deformation of the compressible member,
wherein the bar extends through an aperture in the compressible member,
wherein the non-linear surface is a non-linear section of a groove of the bar, and
further comprising a pin engaging the groove, wherein the groove includes a linear section parallel with a longitudinal axis of the bar and the non-linear section.

2. The motor vehicle as recited in claim 1 , wherein the door check mechanism includes at least one detent configured to contact a recess in the bar to hold the door in the fully open check position.

3. The motor vehicle as recited in claim 2 , wherein the detent is biased toward the recess by a spring.

4. The motor vehicle as recited in claim 1 , wherein the pin is embedded in the compressible member.

5. The motor vehicle as recited in claim 1 , wherein, when the pin engages the non-linear section, the compressible member is torsionally deformed.

6. The motor vehicle as recited in claim 1 , wherein the non-linear portion diverges from the longitudinal axis of the bar.

7. The motor vehicle as recited in claim 1 , wherein the non-linear portion is helical.

8. A motor vehicle, comprising:
a pivotable door;
a door check mechanism including a bar, wherein the door check mechanism is configured to hold the door open in a fully open check position; and
a retarder assembly configured to oppose opening of the door beyond the fully open check position by applying a retarding force to the door, wherein the retarding force is generated by interaction between the retarder assembly and a non-linear surface of the bar,
wherein the door check mechanism includes at least one detent configured to contact a recess in the bar to hold the door in the fully open check position,
wherein the detent is biased toward the recess by a spring,
wherein the bar is attached at a first end to a body of the motor vehicle and is attached to the door via a support housing,
wherein the support housing is attached to a compressible member,
wherein the retarding force includes a reaction force produced by deformation of the compressible member,
wherein the bar extends through an aperture in the compressible member,
wherein the non-linear surface of the bar is a curved portion of the bar or a non-linear portion of a groove of the bar, and
wherein the compressible member is spaced-apart from the at least one detent in a direction toward the non-linear surface of the bar.
