Strap tensioning apparatus

摘要

A strap tensioning apparatus (26) suitable for use in a motor vehicle having strap (11) for retaining a sensor (12) strapped inside a tire/wheel assembly (14) is described. The strap tensioning apparatus includes an arcuate member (28) having a first radius of curvature along a longitudinal axis unequal to the installed radius of curvature. The difference in radii of curvature is such that the arcuate member will maintain a predetermined tension in the strap (11) in the event the strap relaxes during normal use, thus preventing the dislocation of the strap (11) and sensor (16) relative to an installed location.
