Abstract:
An air bag restraint system and control system for controlling an air bag (18) in a vehicle and compensating for ambient temperature variations. The control system includes a temperature sensor (40) for sensing temperature of an air bag device (10), and an air bag controller (30) for controlling actuation of an air bag (18). The controller (30) controls restraining force produced by the air bag (18) as a function of the sensed temperature. Accordingly, the air bag (18) compensates to changes in temperature so as to optimize the air bag performance.
Abstract:
A crash sensing system for determining a vehicle impact includes an electronic controller for activating impact mitigation equipment during both a first stage event and a second stage event. One or more sensors are used for determining the magnitude of both frontal and side impact forces during the vehicle impact. The controller operates to adjust the sensitivity of the sensors based upon vehicle speed measurements.
Abstract:
An elastomeric seat bladder (30) for a vehicle occupant weight estimation system (10) includes a plurality of elastomeric tethers (38) defined by bands or sheets of elastomeric material coupling upper and lower layers (30a, 30b) of the bladder within a peripheral weld (36) in order to reduce fluid pooling and distention or bulging of the bladder (30) due to localized loading. The elastomeric tethers (38) are spot or seam welded to upper and lower sheets (30a, 30b) of the bladder (30); they extend to limit distension where required, and otherwise partially or fully collapse to minimize vertical shunting of occupant weight through the bladder (30).
