Embodiment 1

[0028] Embodiment 1: a kind of safety belt and safety belt use detection system of the present embodiment 1, such as figure 1 and figure 2 As shown, it includes a seat belt webbing 1, a webbing holder 2 connected to one end of the seat belt webbing and fixed on the seat, and a retractor connected to the other end of the seat belt webbing and wound around the seat belt webbing and installed on the vehicle frame 3. The clip that is set on the webbing of the seat belt and can slide along the webbing of the seat belt 4. The buckle that matches with the clip and is installed on the other side of the seat and the seat belt that is installed on the frame on the same side as the retractor Ribbon guide 5, the safety belt webbing is designed with a conductive section 6 with a layer of metal coating, the starting point of the front end of the conductive section is close to the exit of the safety belt webbing of the retractor, and most of the conductive section is wound on the webbing wh...

Embodiment 2

[0030] Embodiment 2: The extension detector of this embodiment 2 is a non-contact detector, comprising a pair of photoelectric emission tubes and photoelectric receiving tubes, the photoelectric emission tubes and photoelectric receiving tubes are installed on the bracket, and the photoelectric emission tubes and photoelectric receiving tubes There is a certain distance between the tube and the surface of the seat belt webbing and a reflection angle is designed to be symmetrical to each other. The laser light emitted by the photoelectric emitting tube is reflected from the surface of the metal coating layer of the conductive section of the seat belt to the photoelectric receiving tube to form a signal loop. Other parts are similar to the corresponding parts of Embodiment 1, and will not be repeated here.

Embodiment 3

[0031] Embodiment 3: The protruding amount detecting device of this embodiment 3 is installed on the webbing guider of the safety belt, such as Figure 5 As shown, the protruding amount detection device is a contact detector, and the other parts of the third embodiment are similar to the corresponding parts of the first embodiment, and will not be repeated here.

Abstract

The invention discloses a seat belt, a seat belt use detection system and detection method. The seat belt comprises a woven belt, a woven belt fastener, a retractor, a clamp, a lock catch matched with the clamp, and a woven belt guide device arranged on a frame, wherein a conductive section is arranged on the woven belt, and a clamp detection device is arranged in the lock catch; and a seat belt extension amount detection device is arranged at a woven belt outlet of the retractor. The insertion of the clamp into the lock catch can be detected, and simultaneously the extension amount of the woven belt is also detected, accordingly, the situation that the seat belt is correctly used is determined by simultaneously meeting two conditions, so that the accuracy of detection is improved, the phenomenon that the normal use of the seat belt is avoided is avoided, and the factor of safety of drivers and passengers is improved.

Description

technical field [0001] The invention relates to the field of automobile active safety design, in particular to a novel safety belt, a safety belt use detection system and a detection method capable of preventing drivers and passengers from avoiding using the safety belt. Background technique [0002] At present, for most models, the only signal to determine whether the driver and passengers are using the seat belt correctly comes from whether the seat belt buckle has been inserted into the slot correctly. Avoid the alarm in the following ways: 1) Use an item similar to a seat belt buckle to replace the seat belt buckle and insert it into the seat belt slot; 2) Or insert the seat belt directly from the back into the seat belt slot. In order to solve this problem, China Patent No. ZL201020669183.3, a utility model patent titled a seat belt monitoring and control device, discloses a seat belt monitoring device, including a safety webbing, a seat belt buckle, and a seat belt hol...
