Abstract
Claims
1. A seat belt device suitable for installation in a vehicle body and for use with a buckle on a seat in the vehicle body, and for signal connection to an in-vehicle system of the vehicle body, the seat belt device comprising: a webbing that can be pulled outward and rolled up in the vehicle body for placement next to the seat; a buckle including an insert portion movably fitted onto the webbing and insertable downward into the buckle, and a body portion mounted outside the insert portion, the body portion having a sensing surface; A communication module, disposed within the main body, is used to wirelessly connect to the vehicle system and can receive a start signal sent by the vehicle system; and a sensor, disposed within the main body and connected to the communication module, is triggered by the start signal to sense the webbing abutting the sensing surface, and when the webbing is not sensed, the sensor generates a trigger signal to drive the communication module to wirelessly send an alarm signal to the vehicle system.
2. The seatbelt device as claimed in claim 1, wherein, The insert has a perforation through which the webbing passes, and the sensing surface is located on the side of the body above the perforation and adjacent to the seat.
3. The seatbelt device as claimed in claim 2, wherein, The webbing is magnetic, and the sensor is an electronic component that can sense changes in the magnetic field.
4. The seatbelt device as claimed in claim 2, wherein, The webbing includes a belt body and a magnetic part sewn into the belt body.
5. The seat belt device as claimed in claim 1 further includes an alarm element disposed within the body portion of the buckle and signal-connected to the sensor, the alarm element being able to receive the trigger signal and, upon receiving it, emit a predetermined warning sound.
6. A seatbelt device suitable for installation in a vehicle body and for use with a seat in the vehicle body, and for signal connection to an in-vehicle system of the vehicle body, the seatbelt device comprising: a fixing unit disposed beside the seat, including an anchor, a retractor on the same side of the anchor on the seat, and a buckle on a different side of the anchor on the seat; a webbing retractable into the retractor and having one end disposed on the anchor; and a fastener including an insert portion movably fitted onto the webbing and capable of being inserted downward into the buckle, and a body portion disposed outside the insert portion, the body portion having a sensing surface; A communication module, disposed within the main body, is used to wirelessly connect to the vehicle system and can receive a start signal sent by the vehicle system; and a sensor, disposed within the main body and connected to the communication module, is triggered by the start signal to sense the webbing abutting the sensing surface, and when the webbing is not sensed, the sensor generates a trigger signal to drive the communication module to wirelessly send an alarm signal to the vehicle system.
7. The seatbelt device as claimed in claim 6, wherein, The insert has a perforation through which the webbing passes, and the sensing surface is located on the side of the body above the perforation and adjacent to the seat.
8. The seatbelt device as claimed in claim 7, wherein, The webbing is magnetic, and the sensor is an electronic component that can sense changes in the magnetic field.
9. The seatbelt device as claimed in claim 7, wherein, The webbing includes a belt body and a magnetic part sewn into the belt body.
10. The seatbelt device as claimed in claim 6 further includes an alarm element disposed within the body portion of the buckle and signal-connected to the sensor, the alarm element being capable of receiving the trigger signal and emitting a predetermined warning sound upon receipt.
