Abstract: In a seat belt guide, a hanger for guiding a seat belt by inserting the seat belt through a belt passing opening is inserted into a hanger guiding portion of a main portion to be moved in a front-to-rear direction. When the hanger is slid forwards by a predetermined distance, a rear end of a sliding groove of the hanger engages with a bolt to thereby swing the hanger in a horizontal direction. Since the seat belt is urged by a spring to a side opposite to a direction in which the seat belt is taken out of the belt passing opening when the seat belt is attached to a passenger, even if the passenger of small build wears the seat belt, the seat belt is not wound round the shoulder of the passenger and the seat belt adjusted to a lower attaching height can be attached to a proper position.

The seat belt webbing payout is independent of the amount of load applied to a spindle body of the hydraulic velocity damper. In one embodiment, two pistons within an elliptical housing of a rotatable spindle body rotate about two independent drive screws. As the pistons rotate about respective drive screws, the pistons move towards each other to pressurize a hydraulic fluid within a chamber defined by the housing.
