Navigation harnesses

Improved traction harness, particularly for navigation, and particularly for a sail surfboard type craft, the harness comprising a chest bolt of adjustable length with shoulder straps adjustable to the size of the user, the belt being provided on the belly side with a rigid plate having an attachment point for a connecting element releaseable by the user, the connecting element having one extremity adapted to be attached to said point and another extremity attached to a part of the craft, and a rip cord adapted to be connected to a body extremity of the user, the improved harness being characterized in that

• the attachment point to the plate for the releaseable connecting element is formed by an open hook having an operating shank and a retaining portion for the connecting element, the hook being positioned in a vertical slot provided in the plate in such manner that the retaining portion of the hook which receives the connecting element is oriented to protrude from the outer face of the plate,
• the said hook being pivotally attached through the vertical slot in the plate, so as to be capable of assuming either of two distinct positions, a hooking-on position for the connecting element in which position the retaining portion and the operating shank of the said hook are approximately parallel to the plane of the plate, and a release position for the said connecting element in which position the retaining portion and the operating shank of the said hook are approximately perpendicular to the plane of the plate,
• the said rip cord being coupled to the hook shank so that simple pulling on the cord by the user causes the hook to assume the said release position, thereby freeing the connecting element.
