Ball and socket assembly

Abstract: A ball and socket assembly may be used in an automotive suspension system. It may include a ball stud having a shaft portion extending from a ball portion, and a bearing having a wall portion defining an open end and an end portion defining a closed end, with the wall portion and the end portion further defining a cavity having the ball portion received therein, and with the open end of the wall portion including a radially outwardly extending seal flange. A shell has a sidewall portion including a generally cylindrical inner surface for receiving the bearing. The sidewall portion of the shell defines an open end face adjacent to the open end of the bearing, with the seal flange of the bearing extending radially outward of the cylindrical inner surface of the shell and substantially covering the open end face of the shell. Also, the assembly provides for securing the shell to the bearing. The assembly may also include a boot having a first open end and a second open end enclosing a portion of the bearing and the ball stud and defining a grease cavity therein, with the second open end including a flange portion disposed between the seal flange and the open end face of the sidewall, and with the first end of the boot sealingly engaging the shaft portion of the ball stud.

Tensioner tube for a seatbelt tensioner

Abstract: A tensioner tube (18) for guiding a force transmission element (20) for a seatbelt tensioner comprises a first open end (30), which is provided for coupling to a pyrotechnic driving device, and a second open end (32), which is provided for aligning with a driving wheel (14) of the seatbelt tensioner, and at least one outflow opening (34) is arranged in the vicinity of the second end (32). A seatbelt tensioner for a seatbelt system comprises a pyrotechnically movable force transmission element (20) and a driving wheel (14) which can be driven by the movable force transmission element (20). The force transmission element (20) is guided in a tensioner tube (18) of the above-mentioned type.

Pre-Crash Performance of Collision Mitigation and Avoidance Systems: Results from the Assess Project

Abstract: Integrated vehicle safety systems that combine elements from primary and secondary safety have a high potential to improve vehicle safety, due to their ability to influence crash conditions and/or to adapt to these crash conditions. So far no standard evaluation procedures have been developed and implemented. The main goal of the ASSESS project is to develop harmonized and standardized assessment procedures for related collision mitigation and avoidance systems. Procedures are developed for: (1) Driver behavior evaluation (2) Pre-crash system performance evaluation (3) Crash performance evaluation (4) Socio-economic assessment. This paper presents the activities related to the "Pre-Crash evaluation". The objective is to provide a tool box for the specific evaluation of the pre-crash performance of collision mitigation and avoidance systems and their contribution to the overall system performance. cop.

Vehicle crash sensor condition tester

Abstract: A crash sensor condition tester for use with a sensor assembly employed for actuating a vehicle safety apparatus upon the occurrence of a collision. The sensor assembly includes an inertia member positioned for movement in response to vehicle deceleration of a predetermined magnitude to actuate an electrical switch means. The switch means, in turn, serves to complete an electrical circuit to energize a detonator. This actuates the safety system which employs a confinement which, upon energization of the detonator, is inflated to an expanded condition. The sensor testing device includes a mechanism to move the inertia member to actuate the switch means. The detonator means is electrically deactivated and an indicator means provides an indication when the switch means is actuated.

Method and apparatus for determining tire condition using ideal gas law

Abstract: An apparatus is provided for determining a tire operating condition including a tire-based sensor for sensing tire pressure and temperature and transmitting a signal indicative thereof and a vehicle ignition system A vehicle-based receiver/controller is provided for receiving the signal from the tire-based sensor and for detecting the state of the vehicle ignition system The controller provides an error signal when the sensed tire pressure is less than a set threshold value P set and resets the error signal when the sensed tire pressure is greater than a reset threshold value P rst The receiver/controller determines the set threshold value P set and the reset threshold value P rst as a function of a calculated warm tire pressure value P warm , determines a mole value N of the tire pressure, and adjusts the determined set threshold value P set and the reset threshold value P rst in response to the vehicle ignition state and a change in the determined mole value N A display is provided for displaying the error signal from the vehicle-based receiver/controller
