ELEVATOR BELT WITH LAYERED LOAD BEARING ELEMENTS
FIG6 is a cross-sectional view of still another embodiment of a load bearing tension member of an elevator system 
Another embodiment is illustrated in FIG6. In this embodiment, the traction sheave 52 has a crowned sheave surface 54. In some embodiments the crown is a constant crown radius 56. In the belt 16, the tension elements 24 are arrayed across the belt 16 in a pattern defined by a tension element curve 58. Each tension element center of the tension elements 24 is located along the tension element curve 58. In the embodiment shown the tension element curve 58 is defined by a tension element radius 60, which is equal to the crown radius 56, but inverted relative to the crown radius 56. This arrangement has the technical effect of equalizing loads on the tension elements 24 regardless of their position along the belt width 26.

['1. 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.', '12. The elevator system of claim 11, wherein the plurality of tension elements are arrayed such that a center of each tension member is positioned along a preselected arc; and, wherein the preselected arc matches a sheave crown of the elevator system.']
