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. Due to the design of the screw means the driving shaft between the motor and the spindle does not prevent the fastening of the bar at the motor end.
