Abstract
This invention relates to a hydrostatically activated release mechanism for vehicles which are subject to accidental submersion in water. The release mechanism contains an activating device, a latching mechanism which is connected to buoyant seat cushions and a mechanism for transmitting movement from the activating device to the latching mechanism. The activating device, which is pressure operated, releases the buoyant seat cushion when the vehicle is submerged in water, thereby providing an emergency floating gear for the passengers of said vehicle.
Claims7
A hydrostatically operated mechanism for releasing a floatation seat cushion comprising an activating device consisting of a hollow body, a flexible wall capable of movement in response to a pressure differential which is secured across said hollow body to form a single chamber which is vented to the atmosphere, and a means for transmitting movement of the flexible wall to a means which releases the floatation cushion.
