Weight sensor for vehicular safety restraint systems |
摘要 |
An weight sensor (16) for use in the crash management system of a motor vehicle's safety restraint system (10). The weight sensor (16) functions to determine the weight of an occupant sitting on a vehicle seat (12) and is mounted between the seat frame (42) and mounting structure (46) of the vehicle seat (12). The weight sensor (16) includes a position sensing unit (52) retained in an enclosed housing assembly (50). The weight of a seat occupant causes a portion (56) of the housing assembly (50) to deflect and the position sensing unit (52) measures the corresponding displacement caused by such deflection. The position sensing unit (52) includes a Hall effect sensor (70) fixed to the rigid portion (54) of the housing assembly (50) and a magnet (74) fixed to the deflectable portion (56) of the housing assembly (50). As such, movement of the magnet (74) relative to the Hall effect sensor (70) generates a varying electric output signal which is indicative of the weight of the occupant or object causing the deflection.
