Abstract: Provided herein are approaches for detecting movement of a seatbelt sensor. In some approaches, a detector includes a sensor housing coupled to a plate of a vehicle restraint system, and a sensor disposed within the sensor housing, wherein the sensor is operable to sense a position of a magnet in proximity to the sensor. The detector further includes a magnetic field accumulator (e.g., a pole-piece) coupled to the sensor, wherein the magnet and the magnetic field accumulator move relative to one another, and wherein the sensor receives an indication of a magnetic field accumulated by the magnetic field accumulator as the magnet and the magnetic field accumulator move relative to one another. A change in the magnetic field distribution correlates to a change in position of the plate, to which the magnet is coupled.

Abstract: A thick film polymer membrane switch can be positioned within a seat belt buckle. The switch can detect if the seat belt buckle is fastened or unfastened. In one approach, an apparatus includes a housing having a cavity, an insertion member moveable within the cavity, a connector positioned within the cavity, and a switch positioned within the cavity, wherein movement of the insertion member causes the connector to connect or disconnect from the switch. In some approaches, the switch includes a first conductive element formed adjacent a first layer of flexible film, and a second conductive element formed adjacent a second layer of flexible film, wherein the first and second layers of flexible film are separated by a gap.

CPC classification number: B60R21/0155 , B60R21/01544 , G01L1/246
Abstract: A plate type tension sensor having apertures, a spring structure, and a gap are provided. The spring structure allows the apertures to move relative to each other as tension is applied to a seat belt to which the plate is attached. The movement changes the width of the gap. The tension applied to a vehicle restraint system may be determined based on the gap width.
Abstract translation: 提供具有孔，弹簧结构和间隙的板式张力传感器。 弹簧结构允许孔相对于彼此移动，因为张力被施加到安装板的安全带。 运动会改变间隙的宽度。 施加到车辆限制系统的张力可以基于间隙宽度来确定。
