Abstract: A motorized height adjuster for adjusting the height of the pillar loop in vehicle safety belts comprises an elongate bar (10) having a substantially U-shaped cross-section; a threaded spindle (14) rotatably mounted in the bar; a motor (18) for driving the spindle; and a carrier (19) for the pillar loop (20) adapted to be moved in the bar by the rotation of the spindle. The bar is adapted to be attached to the car body at the seat for which the seat belt is intended by means of a first and a second screw means. The screw means are positioned close to the different ends of the bar and have a threaded portion and a main portion. The first screw means (23) has a main portion which is designed to be brought into engagement with the bar (10), when the threaded portion has been screwed into the car body. The main portion is provided with a recess through which a driving shaft (17) between the motor (18) and the spindle (14) can pass freely.

Abstract: A safety belt buckle has a slider having first and also second parts each adapted to engage and retain a locking member in a locking condition in which it engages a tongue inserted in the buckle. The slider is spring biassed to a position in which one part engages and retains the locking member and is movable against the spring bias to a second position to permit the locking member to move to release the tongue. The arrangement is such that if the buckle is subjected to a severe force, which moves the slider against the spring bias, the slider moves to a third position in which the second part engages and retains the locking member in the locking position.
