Seat Occupancy Membrane Pressure Sensor for Car Seat





Verification code

►Product name: Seat Occupancy Membrane Pressure Sensor for Car Seat

►Keyword:  Pressure Sensor,Pressure Sensor for Car Seat,Membrane Sensor for Car Seat,seat sensor,seat belt sensor.
The car seat sensor is a film type contact sensor in which the contacts of the sensor are evenly distributed on the force receiving surface of the seat, and a trigger signal is generated when the seat is subjected to pressure from the outside. Used in car seat occupant perception systems, such as seat belt alarm sensors,Taxi automatic meter, airbag sensing and driver departure. For example, with this device, it can sense if there is anyone in the seat, if there is no one, the airbag It won't open.

Design of seat sensor focuses on two perspectives: (1) the shape of the seat (2) the weight trigger value

①Shape of the sensor
The shape and size of the sensor are mainly based on the shape and size of the seat cushion.

In order to make the sensing point in the groove feeling the pressure from above the seat,we have to install the sensor in the core position of the seat cushion, the shape should be basically consistent with the seat, and the measuring point should avoid the grooves on the seat. The size of the sensor should also be the same as the size of the seat cushion, preventing the change in the sitting position of the passenger on the seat of the seat does not affecting the test results.

②The trigger weight value
The seat sensor (SBR) trigger weight is affected by the seat structure, the softness and hardness of the seat cushion, the installation position, and the material of the seat surface. If the same seat sensor was installed into different seat cushions, the performance on trigger weight value and sensitivity will be much different from each other.
In order to get the trigger weight value of SBR, we suggest to measure the surface of one sensing point of it, test the pressure value required for a single point trigger.
The trigger weight value of an adults seat cushion is 30kgs. If the trigger weight value can not meet your requirements, we have to make some modifications on the thickness, softness & hardness of the cushions filler.
Otherwise, we have to make some changes on the design of SBR to meet your requests on trigger weight value.
