Abstract
A frame has a pivot protruding therefrom. A first gear is rotatable relative to the frame. A cam is rotatable with the first gear. A second gear is between the pivot and the cam. The second gear is engaged with the cam for rotation. The second gear is to be rotated on the pivot, thus to be locked with the first gear. The pivot has smaller mechanical strength than the first gear and the second gear.
Claims11
A reclining device comprising:
- a frame having a pivot protruding therefrom, the frame being fixed to a first seat component;
- a first gear rotatable relative to the frame, the first gear being fixed to a second seat component for establishing an angle between the first seat component and the second seat component;
- a cam rotatable to the first gear and with an input component;
- and
- a second gear driven by the cam for rotating on the pivot to lock with the first gear,
- wherein the pivot has smaller strength than the first gear and the second gear,
- so that the pivot is deformed radially outward by the second gear under a predetermined load to mesh with the first gear, with the first and second gears locked with each other so as to prevent rotation of the first gear.
