Problems solved by technology

The sensor used in this installation method is sensitive enough, but it is prone to failure conditions in practical applications
The different material characteristics of the seat upholstery, the occupant's sitting posture and the seat position, etc., may cause the sensor of the seat belt reminder device to trigger a wrong signal; and this installation method is likely to cause the sensor to be damaged by external activities or sharp objects. Difficult to maintain and repair it

Abstract

The invention relates to a compression spring type safety belt reminding device which is used for sending a passenger on an automobile seat. The compression spring type safety belt reminding device comprises a compression spring type safety belt reminding sensor (2), a seat foam mat (3), a seat basin or hanger bracket (4) and an electronic controller (10). The compression spring type safety belt reminding sensor (2) is arranged between the seat foam mat (3) and the seat basin or hanger bracket (4). The bottom face of the seat foam mat (3) is provided with a groove (5) used for installation of the compression spring type safety belt reminding sensor (2). The electronic controller (10) is connected with the compression spring type safety belt reminding sensor (2) through a wire. The compression spring type safety belt reminding sensor (2) is fixedly connected with the seat foam mat (3) or the seat basin or hanger bracket (4). Compared with the prior art, the compression spring type safety belt reminding device has the advantages of being simple in structure, high in reliability, low in manufacturing cost and the like.

Description

Technical field [0001] The invention relates to an automobile safety belt reminding device, in particular to a compression spring type safety belt reminding device. Background technique [0002] Car seat belts are important facilities to ensure the safety of drivers and passengers. According to statistics, wearing seat belts while driving can significantly reduce casualties in accidents. Today's motor vehicles are generally equipped with occupant safety systems, which usually include seat belt reminders and airbag ignition controllers. For example: a seat belt reminder device is combined with a seat belt switch to detect an occupant who is not wearing a seat belt, and then remind the occupant to wear a seat belt with appropriate sound and light signals. [0003] In China, the commonly used method of installing seat belt reminders is to install a pressure sensor between the seat decorative skin and the seat foam cushion. The sensor used in this installation method is sensitive eno...
