摘要： An improved method of producing a fluid filled elastomeric bladder for occupant weight sensing involves annealing the bladder material prior to its installation in a vehicle seat so as to quickly relieve initial stress due to stretching of the bladder material which occurs during fluid injection. In a preferred implementation, the initial stress is relieved by immersing the fluid-filled bladders in heated water for a time period on the order of 60 seconds or more. Alternatively, the bladder material may be heated with steam or radiant heat, by injecting heated fluid into the bladder, or by injecting heated air into an empty bladder before fluid injection. In each case the initial stress is quickly relieved, substantially eliminating a potential source of error in the sensed weight.

摘要： An improved weight estimation apparatus in which an elastomeric bladder is supported on a semi-rigid backer board which is installed in a vehicle seat between the seat cushion and an underlying spring suspension. The bladder is secured onto the backer board, and the backer board is attached to the seat, enabling proper and consistent placement of the bladder relative to the seat surface. The backer board provides the reaction surface for the bladder, and masks non-uniformities of the seat structure. Additionally, the backer board will reduce or eliminate the effect of objects lying on the floor under the seat, which might otherwise pinch the bladder and produce weight estimation errors. Further, the board tends to protect the bladder from damage due to sharp objects, pinching by the suspension elements, and the effects of wires or cables routed through the seat. The backer board may be smooth to provide a uniform reaction surface, or contoured to increase or decrease sensitivity to weight applied on certain areas of the seating surface.

摘要翻译： 一种改进的重量估计装置，其中弹性体囊被支撑在半刚性支撑板上，该半刚性支撑板安装在座垫和下面的弹簧悬架之间的车辆座椅中。 气囊被固定在支承板上，并且支撑板附接到座椅上，使得气囊相对于座椅表面的适当和一致的放置。 支撑板提供了膀胱的反应表面，并掩盖座椅结构的不均匀性。 此外，背板将减少或消除躺在座椅下面的地板上的物体的作用，否则可能会夹住膀胱并产生重量估计误差。 此外，板倾向于保护膀胱免受尖锐物体的伤害，由悬挂元件夹住，以及穿过座椅的电线或电缆的影响。 支撑板可以是平滑的以提供均匀的反应表面，或者轮廓以增加或降低施加在座面的某些区域上的重量的灵敏度。
