Abstract
A load bearing tension member for an elevator system includes a plurality of tension elements arrayed across a tension member width. The tension elements are offset from a tension member central axis, the central axis bisecting a tension member thickness and extending across the tension member width. The tension elements include a plurality of fibers extending along a length of the tension element, and a matrix material in which the plurality of fibers are embedded. A jacket at least partially encapsulates the plurality of tension elements.

A load bearing tension member for an elevator system, comprising:
- a plurality of tension elements arrayed across a tension member width, the tension elements offset from a tension member central axis bisecting a tension member thickness and extending across the tension member width, the tension elements including:
- a plurality of fibers extending along a length of the tension element;
- and
- a matrix material in which the plurality of fibers are embedded;
- and
- a jacket at least partially encapsulating the plurality of tension elements;
- wherein the plurality of tension elements are arranged in a single layer across the tension member thickness and a center of each tension element is positioned along a preselected arc.
An elevator system, comprising:
- a hoistway;
- an elevator car movable along the hoistway;
- and
- one or more tension members operably connected to the elevator car to move the elevator car along the hoistway, a tension member of the one or more tension members including:
- a plurality of tension elements arrayed across a tension member width, the tension elements offset from a tension member central axis bisecting a tension member thickness and extending across the tension member width, the tension elements including:
- a plurality of fibers extending along a length of the tension element;
- and
- a matrix material in which the plurality of fibers are embedded;
- and
- a jacket at least partially encapsulating the plurality of tension elements;
- wherein the plurality of tension elements are arranged in a single layer across the tension member thickness and a center of each tension element is positioned along a preselected arc.
