ABSTRACT:
An obstacle proximity warning device for vehicles having an ultrasonic transceiver, for sending an ultrasonic signal and receiving the ultrasound reflected by an obstacle, a receiver signal process means connected to the ultrasonic transceiver, to generate trigger signals upon a threshold level signal being received from the ultrasonic transceiver, an alarm means responsive to the trigger signals, a housing in which the ultrasonic transceiver is mounted and a mounting bracket for fixedly mounting the housing to the vehicle. The mounting bracket has a resilient coating adapted to substantially absorb ultrasonic vibrations generated by the ultrasonic transceiver, to prevent the radiation of ultrasonic vibrations from other elements of the vehicle or the mounting bracket.
