    • A sensor pad for controlling the deployment of an automobile airbag. Weight sensing pad 10 is used in the seat 54 of an automobile, (not illustrated), to detect the presence of an occupant on the seat. Weight sensing pad 10 is used in conjunction with the vehicle's airbag control module in order to allow deployment of the airbag, in the event of a collision, only if the seat is occupied by a person of a preselected weight. Weight sensing pad 10 is defined by a bladder member 15 having an interior volume subdivided into a plurality of individual cells 42 in fluid communication with each other and that is filled with a non-compressible fluid 18, such as silicon or a silica gel of medium viscosity. A pressure tube 22 is in fluid communication with bladder 15 and is in further fluid communication with a pressure activated electronic transducer 26 which in turn is in electronic communication with the airbag controller 30. When a person sits upon weight sensing pad 10, there is a volumetric displacement of fluid 18 that provides a pressure change in the bladder member. If there is a sufficient pressure change due to the volumetric displacement of fluid to activate transducer 26, transducer 26 sends a signal to air bag controller 30. Electronic transducer 26 is selected to generate a signal upon detection of pressure resultant from the volumetric displacement of fluid 18 from bladder 15 expected from the average size adult of approximately one hundred pounds or heavier.
    • 一种用于控制汽车安全气囊展开的传感器垫。 重量检测垫10用于汽车的座椅54(未示出),以检测座椅上乘员的存在。 重量检测垫10与车辆的安全气囊控制模块一起使用,以便在发生碰撞的情况下,只有当座椅被预选的重量的人占据时才允许展开安全气囊。 重量感测垫10由具有细分为彼此流体连通的多个单独电池42的内部体积的气囊构件15限定,并且填充有不可压缩流体18,例如硅或介质硅胶 粘度。 压力管22与气囊15流体连通,并且与压力激活的电子换能器26进一步流体连通,压力激活的电子换能器26又与气囊控制器30电子连通。当一个人坐在重量感应垫10上时, 在膀胱构件中提供压力变化的流体18的体积位移。 如果由于流体的体积位移而产生足够的压力变化以激活换能器26,则换能器26向气囊控制器30发送信号。电子换能器26被选择以在检测到来自流体的体积位移的压力 18岁从膀胱15预期从平均成年人大约一百磅或更重。
