摘要： An improved vehicle crash sensing apparatus quickly and reliably characterizes frontal impacts with only minimal data processing requirements. Two or more longitudinally separated piezoelectric strips strategically located in a frontal portion of the vehicle produce impact signals that are analyzed to characterize the type of impact and the structural crush rate. In a simple implementation involving only two piezoelectric strips, a first strip extends laterally along a forward portion of the front bumper, and a second strip extends laterally along a forward portion of the hood panel, above and rearward of the first strip. In cases where an impact signal is developed by only one of the two strips, a high (under-ride) or low (over-ride) impact is indicated. If impact signals are developed by both strips, the intervening time is measured as an indication of the structural crush rate. In a more complex implementation, the bumper and hood strips are divided into two or more individual strip segments so the center and distribution of impact and the impact vector may be quickly and reliably characterized as well.

摘要： An improved weight-based occupant characterization method that can inexpensively and reliably distinguish between a child or small adult and a tightly cinched child seat. When the sensed weight is in a specified range that could be produced by a tightly cinched child seat, the system characterizes the occupant based on a detected variation in sensed weight during movement of the vehicle. If the variance of the sensed weight is below a threshold for a predetermined interval, the occupant is characterized as a child seat, since a tightly cinched seat belt severely restricts variance. If the variance exceeds the threshold for a predetermined interval, the occupant is characterized as a child or small adult. A correlative factor that can be used in distinguishing between a child seat and a child or small adult is determined by computing a slope reversal rate, or frequency, of the measured weight. In this case, a child seat is indicated by the combination of low variance and a high frequency, whereas a child or small adult is indicated by the combination of high variance and a low frequency. Additionally, movement of the vehicle can be detected when the variance of the sensed weight is within a predetermined range for at least a predetermined interval.
摘要翻译：改进的基于重量的乘员表征方法，其可以廉价和可靠地区分儿童或小成人和紧密束缚的儿童座椅。当感测到的重量在可以由紧密束缚的儿童座椅产生的指定范围内时，系统基于在车辆移动期间检测到的重量变化来表征乘员。如果感测到的重量的差异在预定间隔内低于阈值，则乘客被表征为儿童座椅，因为紧紧的安全带严重限制了变化。如果方差超过阈值达预定间隔，乘客被表征为儿童或小成人。通过计算测量重量的斜率反转率或频率来确定可用于区分儿童座椅和儿童或小成人的相关因素。在这种情况下，儿童座椅由低方差和高频率的组合表示，而小孩或小成人由高方差和低频率的组合表示。此外，当感测到的重量的变化在至少预定间隔内在预定范围内时，可以检测车辆的移动。

摘要： The airbag system includes in addition to conventional crash sensing apparatus seat sensors to gauge occupant mass, an occupant position sensor and a vehicle speed sensor. Desired initial restraining force is calculated from speed at impact and the occupant's mass, and an appropriate degree of inflation is effected. The occupant speed is continuously calculated from the position sensor signal and the vehicle speed. A target speed profile is established based on an estimated restraint period and the vehicle speed, and an airbag vent is varied to control the occupant speed to the target speed. The target speed profile is adjusted as a function of passenger compartment acceleration to account for vehicle speed variations and for vehicle crush.

摘要： A method and apparatus for controlling the deployment of a passive inflatable restraint system wherein driver and passenger air bags are employed each having two independently actuatable gas generators of the same or different sizes which are activated in a fixed time sequence. The sequence is timed to provide an initial low inflation rate to just open the airbag container and initially deploy the airbag followed by a higher gas flow rate to complete filling of the cushion. An electronic control unit containing a control algorithm and connected to external sensors monitors vehicle decelerations, detects impacts, and determines if impact severity warrants deployment of an airbag for occupant protection. The external sensors include one or more sensors located in the forward portion of the vehicle to provide early impact detection and crash severity indications; a weight based occupant detection system located in the passenger seat to identify infants and small children and provide airbag suppression; and a seat belt mode or seat belt tension sensor to determine the presence of a cinched child seat and provide additional airbag suppression. The control algorithm monitors the above described sensors and if a deployment is required, a signal for activating the first initiator and a second signal for activating the second initiator are provided, the second signal being delayed a predetermined time after the first signal is generated.

摘要： An air bag restraint system and control system for controlling an air bag in a vehicle and compensating for ambient temperature variations. The control system includes a temperature sensor for sensing temperature of an air bag device, and an air bag controller for controlling actuation of an air bag. The controller controls restraining force produced by the air bag as a function of the sensed temperature. Accordingly, the air bag compensates to changes in temperature so as to optimize the air bag performance.

摘要： A modular containment wall for a sports area. The containment wall is an assembly of panels, each panel having a first edge, an opposing second edge, and interlocking members configured and arranged for (i) interlocking the first edge to a first adjacent panel and (ii) interlocking the second edge to a second adjacent panel. Support legs are rotatably disposed on a back wall of the panels. Each support leg is removably attachable to at least three different attachment sites at the back wall of a panel. The interlocking, modular design of the containment wall enables quick and easy assembly and reassembly, as well as modification to form door ways, sitting areas and similar component structures. In one embodiment, the rear side of the panel includes a recess formed therein. During periods of nonuse, the support leg can be rotated into the recess in a storage position, permitting easy stacking and storage of the panels with the support legs neatly disposed in the rear recesses.

摘要： An elastomeric seat bladder for a vehicle occupant weight estimation system includes a plurality of elastomeric tethers defined by bands or sheets of elastomeric material coupling upper and lower layers of the bladder within a peripheral weld in order to reduce fluid pooling and distention or bulging of the bladder due to localized loading. The elastomeric tethers are spot or seam welded to upper and lower sheets of the bladder; they extend to limit distension where required, and otherwise partially or fully collapse to minimize vertical shunting of occupant weight through the bladder.

摘要： A vehicle restraint control system provides sophisticated, adaptable control of occupant restraints through the use of a system level architecture to predict the nature of a crash event at the earliest possible time and an occupant injury model to tailor the restraint deployment in an adaptable way to characteristics of the protected vehicle occupant(s) and the nature of the crash event. The occupant injury model derives the potential for injury in a particular vehicle crash in real time as a function of occupant mass, vehicle interior stiffness and occupant impact velocity with respect to the vehicle interior. Peak vehicle crush zone velocity is used as a predictor of occupant impact velocity with the vehicle interior. Predicted occupant impact velocity is preferably adjusted in response to derived impact angle factor, which is derived from orthogonal lateral and longitudinal accelerometers in the vehicle occupant compartment. Vehicle longitudinal velocity may be integrated to predict occupant displacement, relative to the vehicle, as an additional factor used in the control system.
