Tray latching device

A tray latching device comprising:

• a latch including a hook panel to catch an end of a clasp panel that protrudes from a side of an automobile tray, a heart cam to release the clasp panel of the tray from the hook panel when a predetermined stroke is applied thereto by the clasp panel of the tray, and a plurality of supporting indentations each formed with a plurality of stepped supporting portions;
• a housing including a passage to allow the latch to move therethrough so that the hook panel of the latch catches the clasp panel, a fixture lever to move in one direction along the heart cam in accordance with the movement of the latch to be fixed in a restrictive dent of the heart cam and to be separated from the restrictive dent if a predetermined stroke is applied thereto, and a spring to be pressed by the latch;
• and
• a plurality of inertial sensors each including a supporting portion to be coupled to the housing via a shaft, and an extension that protrudes from the supporting portion to support an innermost stepped supporting portion of one of the indentations of the latch, the extension configured to rotate by collision inertia to support an outermost stepped supporting portion of one of the indentations of the latch to suppress a stroke that causes unintentional separation of the fixture lever from the heart cam and configured to be elastically returned to support the innermost stepped supporting portion simultaneously with the removal of the collision inertia,
• wherein the innermost stepped supporting portion is a step provided in the indentation toward the tray, and
• an end of the extension is configured to contact the innermost stepped supporting portion upon removal of the collision inertia.
