1. A webbing height adjusting device adapted to be connected to a main webbing extending out from a webbing retractor of a seat belt system of a vehicle, and the webbing height adjusting device comprising:
a shock absorbing component having
a D-loop configured to be connected to an upper position in the vehicle and configured for the main webbing to be mounted therethrough, thereby the D-loop dividing the main webbing to a rear section and a front section;
a supplementary webbing configured to be located between the rear section and the front section of the main webbing and having
a top end connected to the D-loop;
a bottom end being opposite to the top end and configured to be connected to a lower position in the vehicle; and
at least one flexible section; and
at least one elastic element located beside said flexible section and having two opposite ends fixed to two opposite ends of said flexible section respectively; and
a webbing height adjusting unit disposed below the D-loop, configured to be connected to the front section of the main webbing and the supplementary webbing to form an adjustable top position, and having
an adjuster base having
a frame;
a webbing-abutting portion formed on an upper section of the frame; and
a sliding space formed between the webbing-abutting portion and the frame;
a webbing-mounting portion formed on a lower section of the frame; and
a main webbing slot formed in the webbing-mounting portion and the frame and configured for the front section of the main webbing to be mounted therethrough;
a slider mounted in the sliding space of the adjuster base, configured to move up and down, and having an inclined slot configured for the supplementary webbing to be mounted therethrough;
an elastic member disposed between the slider and the adjuster base and configured to provide a restoring force to allow the slider and the webbing-abutting portion of the adjuster base to clamp the supplementary webbing; and
an outer shell mounted on the adjuster base, configured to move up and down relative to the adjuster base, and being operable to actuate the slider and the adjuster base to move relatively so as to unclamp the supplementary webbing;
wherein when the outer shell is released, the restoring force provided by the elastic member pushes the slider and the adjuster base to move relatively and re-clamp the supplementary webbing.
