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 an elastic cushion type safety belt reminding device. The elastic cushion type safety belt reminding device is used for sensing existence of a passenger on an automobile seat and comprises an elastic cushion type safety belt reminding sensor (2), a seat foam cushion (3), a seat basin or suspension (4) and an electronic controller (14). The elastic cushion type safety belt reminding sensor (2) is arranged between the seat foam cushion (3) and the seat basin or suspension (4), a groove (5) for installing the elastic cushion type safety belt reminding sensor (2) is formed in the bottom surface of the seat foam cushion (3), and the electronic controller (14) is connected with the elastic cushion type safety belt reminding sensor (2) through a wire (13). Compared with the prior art, the elastic cushion 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 an elastic pad type safety belt reminding device. Background technique [0002] Car seat belts are an important facility to ensure the safety of drivers and passengers. According to statistics, wearing seat belts while driving can significantly reduce casualties in accidents. Current motor vehicles are generally equipped with occupant safety systems, which usually include seat belt reminder sensors and airbag ignition controllers. For example: the seat belt reminder device is combined with the seat belt switch to detect an occupant who is not wearing a seat belt, and then reminds the occupant to wear the seat belt with appropriate sound and light signals. [0003] In China, the installation method of the safety belt reminder device commonly used at present is to install the pressure sensor between the seat trim skin and the seat foam pad. The sensors used in this mo...
