ABSTRACT:
A safety restraint sensor system for detecting a latched position and/or an unlatched position of a latch and a buckle. The latch is movably mounted with respect to a housing. A vane projects from the latch. A magnet and a Hall element are mounted with respect to the housing. When the buckle engages the latch, the vane and the buckle move within the magnetic field of the magnet. A magnetic field is distributed through the Hall element by way of the buckle and the vane. The Hall element sends a signal indicating the latched position to an appropriate receptor, such as a safety restraint.
