    摘要： A releasable fastener for securing together lap belt straps, shoulder harness straps and a parachute ripcord lanyard. The fastener includes a buckle member or release assembly on one lap belt interengageable with a tongue member or link assembly on the other lap belt. A key on the end of the ripcord lanyard is releasably attached to the link assembly. The shoulder harness straps are engaged with the release assembly before it is coupled with the link assembly. The fastener provides for automatic release of the lap belt and shoulder harness straps to release the user from an aircraft ejection seat after its ejection from the aircraft, while retaining the parachute ripcord in attachment to the ejection seat for initiating automatic deployment of the parachute. Upon manual release of the fastener, the lap belt and shoulder harness straps are released and the ripcord lanyard key is positively ejected from the fastener to ensure its release.

    摘要翻译： 一个可拆卸的紧固件，用于固定在一起的腰带皮带，肩带束带和降落伞拉索挂绳。 紧固件包括在一个搭接带上的带扣构件或释放组件，其与另一个腰带上的舌构件或连杆组件相互接合。 撕开绳索末端的钥匙可拆卸地连接在连杆组件上。 在与释放组件联接的连接组件之前，肩带束带与释放组件接合。 紧固件提供腰带和肩带束带的自动释放，以在从飞行器弹出之后将使用者从飞行器弹出座释放，同时将降落伞拉索保持在与弹出座位相连以起动降落伞的自动展开。 在手动释放紧固件时，释放腰带和肩带束带，并将拉索系绳从紧固件中正确地弹出以确保其释放。
