摘要： The object of the present invention is to provide a seat-occupant sensing device for a car seat, such that a heater can be installed in the seat without deterioration of sitting comfort.
A load sensor (50) is mounted to a cushion frame (21) of a car seat. The end of a flexible cushion support (25) is linked with the load sensor (50). Because the flexible cushion support flexes when a person sits on the seat, the load sensor senses when the person sits on the seat.摘要翻译： 本发明的目的是提供一种用于汽车座椅的座椅乘员检测装置，使得加热器可以安装在座椅中而不会降低坐姿舒适度。 负载传感器（50）安装到汽车座椅的坐垫框架（21）上。 柔性衬垫支撑件（25）的端部与负载传感器（50）相连。 因为当人坐在座椅上时，柔性缓冲垫支撑件弯曲，所以负载传感器感测人何时坐在座椅上。

摘要： In a vehicle seat, a central support member typically consisting of wire mesh or grid and supports most of the load of the vehicle occupant via spring members, and undergoes a relatively large displacement when the occupant is seated in the seat. Thus, by detecting the displacements of various parts of the central support member, preferably peripheral parts thereof, the magnitude of the total load and distribution of the load can be evaluated both reliably and accurately. Additionally, displacement sensors for measuring such large displacements are relatively inexpensive and easy to handle. Also, such sensors would not interfere with the existing seat designs, and would not be adversely affected by the equipment of the seat such as seat heaters.
