Description
Technical field
The utility model relates to correct the technical field of the seat, more specifically a kind of seat sitting posture monitoring device.
Background technique
Existing correcting sitting posture seat multi-pass over-voltage force snesor detects sitting posture posture, such as Patent No.
A kind of 2012203755103 Chinese patent, publicity preventing sitting posture undesirable seat unit, is sensed using multipoint mode weight
Device, i.e. a back sensor and two waist sensors, to judge whether sitting posture is rectified.
The pressure sensitive of backrest is identified when sensors with auxiliary electrode is sat on the seat by human body waist or back whether
By back, since that there are sensitivity is low for pressure sensor, the disadvantages of dynamic response is slow, easy mechanical fatigue, if user wears
Fluffy down jackets are even in the case where normally wearing, even if waist and back are bonded backrest just, and backrest does not receive
If enough pressure, the back position of user can not just be identified by the seat of such sensor.The seat also can not just judge
Whether user's sitting posture is rectified.Therefore, it is badly in need of a kind of seat sitting posture monitoring device that discrimination is high.
