THE GEOMETRICAL BASIS OF SEAT-BELT FIT

It is proposed that problem of seat-belt fit may be examined by planar development, since when the surface over which the seat-belt passes is developed, its path becomes a straight line. A simple geometric representation of the occupant is suggested for use with such development methods, together with suitable dimensions representing 10th percentile female and 95th percentile male occupants. Criteria are given for determining whether the lie of the seat-belt is acceptable. The paper gives worked examples to illustrate the method, and an appendix contains a description of its mathematical basis. (A)
