摘要： A vehicle seat assembly (12) is mounted to a vehicle base member (24) such as a riser or a vehicle floor. Weight sensor assemblies (32) for measuring weight on the vehicle seat (12) are mounted to a seat structural component. The weight sensor assemblies (32) each include plate (44) having a bendable center body portion (46) for supporting a strain gage (48). The strain gage (48) measures bending in the center body portion caused by normal weight force applications on the vehicle seat (12). A secondary resilient beam member (34) is mounted between each weight sensor (32) and the vehicle base member (24). The beam member (34) and the weight sensors (32) deflect to prevent failure of the weight sensors (32) in response to an overload force applied in an opposite direction to the direction of a normal weight force application. The beam member (34) prevents permanent deformation of the plate (44) and strain gage (48) failure by allowing the weight sensor (32) to deflect upwardly away from the vehicle floor. An overload stop (68) reacts between the seat structural component and the vehicle floor to prevent seat separation under overload conditions.

摘要： A system for measuring seat belt forces is used to control deployment of vehicle airbags. The system includes a rigid plate member having one end attached to a portion of the seat belt and an opposite end mounted to a vehicle structure. The seat belt is used to secure passengers or an infant car seat to the vehicle seat. A sensor including a strain gage is mounted on the rigid plate between the ends and is used to measure the magnitude of forces exerted on the seat belt by the passenger or car seat. The strain gage generates a signal representative of the tension in the seat belt, which is used to control deployment of the airbag. The airbag is not deployed if the tension in the seat belt exceeds a predetermined limit.

摘要： A method and apparatus is provided that classifies a seat occupant into one of several different weight classes based on an estimated value of the seat occupant weight. An occupant's measured weight varies when the occupant's seating position changes or when the vehicle travels over adverse road conditions. A plurality of weight sensors are used to measure the weight exerted by a seat occupant against a seat bottom and are used to determine center of gravity for the seat occupant. A seat belt force sensor is also used to assist in classifying the seat occupant. Compensation factors using the seat belt force and center of gravity information are used to generate an estimated weight value. The estimated value of the occupant weight is compared to a series of upper and lower weight thresholds assigned to each of the weight classes to generate an occupant weight sample class. Over a period of time. Several estimated weight values are compared to the weight class thresholds. Once a predetermined number of consistent and consecutive occupant weight sample classes is achieved, the occupant is locked into a specific occupant weight class. When the weight class is locked, the separation value between the upper and lower thresholds is increased to account for minor weight variations due to adverse road conditions and changes in occupant position.
摘要翻译：提供了一种方法和装置，其基于座椅乘员重量的估计值将座椅乘员分为几个不同的重量级中的一个。当乘员的座椅位置发生变化或车辆在不利的道路条件下行驶时，乘客的测量重量会发生变化。使用多个重量传感器来测量座椅乘员施加在座椅底部上的重量并且用于确定座椅乘员的重心。座椅安全带力传感器也用于帮助分类座椅乘员。使用安全带力和重心信息的补偿因子用于生成估计的重量值。将乘员重量的估计值与分配给每个重量类别的一系列上和下重量阈值进行比较，以生成乘员重量样本类别。经过一段时间。将几个估算的重量值与重量级别阈值进行比较。一旦达到预定数量的一致且连续的乘员体重样本类别，乘客就被锁定在特定的乘员体重等级中。当重量级别被锁定时，上限和下限之间的分离值会增加，以解决由于不利的路况和乘员位置变化引起的轻微重量变化。

摘要： A sensor assembly is used to measure the weight of an occupant (20) seated on a vehicle seat (12). The sensor assembly is integrated into a bracket (18) that is mounted between a seat structure such as a track assembly (38) and a vehicle structure such as floor (30) or riser. One bracket is mounted on an inboard side of the seat and a second bracket is mounted on an outboard side of the seat. Each bracket (18) includes opposing end mounts that are mounted to the vehicle structure. Between the opposing ends, each bracket includes a pair of deflectable portions (34) that define a mount interface for attachment to the seat structure. A central body (42) extends between the deflectable portions (34) to form unitary bracket member that includes the end mounts, the deflectable portions (34) and the central body (42). A strain gage is mounted on each deflectable portion to measure the weight of the seat occupant.

摘要： Weight sensor assemblies for measuring weight on a vehicle seat are mounted at the connecting points between a seat bottom frame and a seat mounting member. The weight sensor assemblies each include a beam member having a bendable center body portion for supporting a stain gage. the strain gage and associated traces are screen printed on the surface of the beam. The beam acts similar to a dual constrained cantilever beam, concentrating the bending at a reduced neck section that narrows in the middle of the center body portion. The strain gage measures strain resulting from bending in the center body portion caused by a weight force being applied against the seat.
