Abstract: A fastening device for facilitating temporary fastening of an electronic component to a circuit board. The fastening device includes a base embedded in an electronic device and two elastic plates extending from the base. Each elastic plate includes a diagonal portion, which extend diagonally relative to the plane of the circuit board, and a leg, which extends continuously from the diagonal portion. When the legs are inserted through a connecting hole of the circuit board, the resilient force of the elastic plates presses the diagonal portions against the wall of the connecting hole.

Abstract: In an assistant apparatus for fastening a webbing, which is adapted to move an intermediate portion of a webbing in the front direction of a vehicle for aiding an occupant of the vehicle in fastening the webbing around the occupant, a reach arm is provided which supports the webbing passing through the reach arm. The reach arm is capable of being swung in the front and rear directions of the vehicle and is always urged in the front direction by a return spring. The reach arm can be held in a rearward position by a cam engaging therewith, the cam being disengaged by a solenoid when the solenoid is energized. Therefore, a complicated gearing mechanism is unnecessary for driving the reach arm.
