Abstract
A check link assembly includes a link and a housing. The link includes a first link end portion, a second link end portion opposite the first link end portion, a first sidewall disposed between the first link end portion and the second link end portion, a second sidewall disposed between the first link end portion and the second link end portion, and a link extension protruding from the second link end portion. The link extension is closer to the first sidewall than to the second sidewall. The housing is movably coupled to the link and is configured to move relative to the link between a first housing position and a second housing position. The housing includes a mechanical stop disposed closer to the first sidewall than to the second sidewall.

A check link assembly, comprising:
- a link including a link body elongated along a longitudinal axis, the link body including a first link end portion, a second link end portion opposite the first link end portion, a first sidewall disposed between the first link end portion and the second link end portion, and a second sidewall disposed between the first link end portion and the second link end portion, wherein the link includes a link extension protruding from the second link end portion in a direction substantially perpendicular to the longitudinal axis, the link extension has a first extension end directly coupled to the link body and a second extension end opposite the first extension end, the second extension end is farther from the link body than the first extension end, the link extension defines a recess, and the recess is closer to the second extension end than to the first extension end;
- and
- a housing movably coupled to the link such that the housing is movable relative to the link between a first housing position and a second housing position, the housing including a mechanical stop disposed closer to the first sidewall than to the second sidewall;
- wherein the mechanical stop is in direct contact with the link extension when the housing is in the second housing position;
- wherein the recess is sized and shaped to at least partially receive the mechanical stop when the housing is in the second housing position.
A vehicle comprising:
- a vehicle body defining a vehicle interior compartment;
- a vehicle door movably coupled to the vehicle body, the vehicle door being configured to move relative to the vehicle body between an open position and a closed position;
- a check link assembly coupled between the vehicle door and the vehicle body, the check link assembly including:
- a housing coupled to the vehicle door and including a mechanical stop, the housing configured to move concomitantly with the vehicle door;
- a link movably coupled to the vehicle body and the housing, the link including a link body, the link body being elongated along a longitudinal axis and including a first link end portion and a second link end portion opposite the first link end portion, the link further including a link extension protruding from the second link end portion in a direction substantially perpendicular to the longitudinal axis, the housing being movable relative to the link between a first housing position and a second housing position, the link extension has a first extension end directly coupled to the link body and a second extension end opposite the first extension end, the second extension end is farther from the link body than the first extension end, the link extension defines a recess, and the recess is closer to the second extension end than to the first extension end;
- wherein the mechanical stop is in direct contact with the link extension when the vehicle door is in the open position in order to limit movement of the vehicle door;
- and
- wherein the recess is sized and shaped to at least partially receive the mechanical stop when the housing is in the second housing position.
A checklink assembly for distributing strain on sheet of metal panel having multiple strain zones and being pivotally movable with respect to an attached body comprising:
- an elongated link having one end pivotally attachable to the body an another end having a link extension;
- a checklink housing movable along said elongated link and having a mechanical stop inboard with respect to a pivotable attachment of said link to said body and configured as a sidewall to engage and apply sufficient load to said link extension when said housing moves to shift the load on said sheet metal panel sufficiently inboard with respect to said body and the strain zones of said sheet metal panel whereby to enable the downgaging of said sheet metal panel;
- wherein the checklink housing is movable relative to the link between a first housing position and a second housing position;
- wherein the link extension has a first extension end directly coupled to the link body and a second extension end opposite the first extension end, the second extension end is farther from the link body than the first extension end, the link extension defines a recess, the recess is closer to the second extension end than to the first extension end;
- and
- wherein the recess is sized and shaped to at least partially receive the mechanical stop when the checklink housing is in the second housing position.
