Device for activating a functional equipment unit of a motor vehicle provided with a safety device

摘要

The electric motor (1) is mounted on the equipment by a pivot link. Reset springs (25,26) return the motor to a neutral position with respect to the equipment. One at least of the springs is calibrated. The safety device has a measuring system (31,32) which includes a resistive gauge whose resistive part is fixed with respect to the equipment and the resistance is a function of the position of the motor with respect to the resistive gauge (32). Activating mechanism for a functional piece of automobile equipment. The mechanism includes an electric motor (1), a transmission (17) connected to and output shaft (12) of the motor and to the functional equipment so that the transmission and the motor exert mutual force on one another. The motor is fitted with a security device to modify its electrical supply as a function of a significant operating parameter of the mutual forces. The motor is mounted on the equipment with at least a degree of displacement with respect to the latter. The security device has at least means (31,32), for measuring the motor displacement, which delivers signals which determine the operating parameter.
