Abstract

The invention provides an auto seat cushion with heating and pressure sensing functions and adopts the technical points that the auto seat cushion with the heating and pressure sensing functions comprises a pressure sensor arranged on a seat cushion and is characterized in that the pressure sensor comprises plastic film layers which are arranged in a corresponding manner; an aluminium foil layer conducting circuit and a carbon paste conducting layer are printed on each plastic film layer in sequence; each carbon paste conducting layer comprises a sensing circuit and a heater circuit; the plastic film layers printed with printed circuits are bonded together through a middle layer to form a composite structure; a plurality of sensing units capable of measuring the load on the automobile seat repeatedly are arranged in the composite structure; the tail end of the pressure sensor is connected with a plastic seal block; a core board is arranged in the plastic seal block and used for processing the resistance value signals of all the sensing units in a classified manner; and the core board is connected with an electric control center of a safe air bag of the whole automobile. The auto seat cushion with the heating and pressure sensing functions has the advantages of being simple and convenient to mount, having a concise appearance, and controlling the popup amount of the air bag to remind passengers of tying the safety belts well.

Description

technical field [0001] The invention relates to a safety belt reminder for vehicle occupants in the aspect of vehicle passive safety, and a pressure sensing device for classifying and protecting the occupants with airbags. It is used to judge and identify the condition of the occupant or object on the car seat, so as to take effective measures to remind the occupant to fasten the seat belt or provide airbag classification protection for the occupant, and also involves the car seat heating device. Background technique [0002] At present, with the further improvement of vehicle safety regulations, CNCAP also has clear evaluation criteria for new vehicle occupant protection measures. The invention can more effectively improve the use effect of the safety airbag and improve the safety performance level of the vehicle by providing detailed information on the occupants of the vehicle. The national road safety regulations of the United States put forward clear regulatory requirem...
