Abstract: A releasable joint configured to attach a cradle to an underbody of a vehicle subjectable to an external force includes a fastener, an attachment portion of the cradle, and a partial sleeve. The fastener attaches the cradle to the underbody. The attachment portion of the cradle encircles the fastener and includes a breakaway portion that fractures when the external force exceeds a threshold force. The partial sleeve is attached to and disposed within the attachment portion of the cradle and partially encircles the fastener so as to form an opening that provides a horizontal pathway for the fastener to move through to exit the cradle when the breakaway portion fractures. The cradle may separate from the underbody at the releasable joint with no vertical motion of the cradle relative to the underbody when the external force exceeds the threshold force.

Abstract translation: 可释放接头被构造成将托架附接到能够受到外力的车辆的底部包括紧固件，托架的附接部分和部分套筒。 紧固件将摇篮连接到底部。 托架的附接部分包围紧固件，并且包括当外力超过阈值力时断裂的分离部分。 部分套筒附接到并设置在支架的附接部分内并且部分地环绕紧固件，以便形成开口，当分离部分断裂时，该开口提供用于紧固件移动通过以离开托架的水平路径。 当外力超过阈值力时，托架可以在可释放接头处与底座分离，在托架相对于底部没有垂直运动时。
