Stress reduction gear and apparatus using same

A door lock mechanism for use in an automotive vehicle, said door lock mechanism comprising:

• a housing having an opening;
• a moveable latch accessible from said opening of said housing;
• a drive transmission disposed within said housing operably driving said latch;
• a stress dissipation rotatable member located within said drive transmission, said stress dissipation rotatable member including a rim and a hub, at least a first structure inwardly projecting from said rim, at least a second structure outwardly projecting from said hub, a deformable member located between said structures, said rim being movable substantially independent from said hub;
• a first set of gear teeth mounted to said stress dissipation member movable concurrent with said rim;
• and
• a second set of gear teeth mounted to said stress dissipation member offset from said first set of teeth, said second set of teeth being movable concurrent with said hub;
• said stress dissipation rotatable member operably reducing sudden movement stresses within said drive transmission.

A door lock mechanism for use in an automotive vehicle, said door lock mechanism comprising:

• a housing having an opening;
• a linearly moveable latch accessible from said opening of said housing;
• a drive transmission disposed within said housing operably driving said latch;
• a stress dissipation rotatable member located within said drive transmission, an anti-buckling plate attached to said stress dissipation rotatable member, said stress dissipation rotatable member operably reducing sudden movement stresses within said drive transmission;
• and
• a pinion gear rotatably coupled to said stress dissipation rotatable member;
• a rack enmeshing with said pinion gear, said rack being coupled to said latch in a lost motion manner whereby said rack is linear moveable a predetermined distance prior to coincidental movement of said latch.
