Abstract: An outer end portion of a webbing is guided in the longitudinal direction of the vehicle, and a tongue plate provided on said outer end portion is engaged with a buckle device secured to the rear portion of a roof side, whereby the webbing is fastened to an occupant. A release plate movable a certain distance with respect to the tongue plate is moved forwards in the vehicle by drive means, whereby the tongue plate is moved forwards in the vehicle after the tongue plate is disengaged from the buckle device, so that the webbing can be separated from the occupant to automatically unfasten the webbing from the occupant.

Abstract: A miniature self-starting electric motor includes a rotor shaft rotatably disposed in a casing. Two rotors fixed to said rotor shaft each have a circular body portion of soft magnetic material, said circular body portion having a periphery with pole teeth extending therefrom and spaced from each other at equal angular spacings. Two exciting coils each are disposed to face the pole teeth. Two magnets each provide radially north and south poles alternating at an equal angle with axially same polarities as the other magnet and facing the pole teeth, the number of poles on each permanent magnet being an even multiple of the number of pole teeth. The two rotors are in an opposite relation each other, the pole teeth of one of said two rotors being staggered from the pole teeth of the other by a predetermined electric angle. A condenser is selectively connectible to either one of said two exciting coils. Such miniature self-starting motor rotates reliably in a predetermined direction at the time of starting.
