HEIGHT-ADJUSTABLE DEFLECTION DEVICE FOR A THREE-POINT SEAT-BELT, VEHICLE SEAT COMPRISING A THREE-POINT SEAT-BELT AND METHOD FOR ADJUSTING THE HEIGHT OF THE UPPER RETAINING POINT OF A THREE-POINT SEAT-BELT

摘要

The invention relates to a height-adjustable deflection device (3) for the upper retaining point (23) of a three-point seat-belt (2), with a retainer (4), which can be connected in a fixed manner to a support element (9) of a vehicle seat (1) or can be connected in a fixed manner to the frame of a vehicle. A deflection element (11) is displaceably mounted in the retainer (4), said element comprising a roller (12) with a rotational axis (13), over which the belt strap (29) of a three-point seat-belt (2) is guided and a housing (24) comprising an exit slot (15) for the belt strap (29), said slot running parallel to the rotational axis (13) of the roller (12). First connecting means (7) are configured on the retainer (4) and second connecting means (17) are configured on the deflection element (11). Said means mesh with one another in a positive fit in a locked position and do not mesh in an adjustment position, permitting the deflection element (11) to rotate about the rotational axis (13). The invention also relates to a vehicle seat (1) comprising a three-point seat-belt (2) with an inventive height-adjustable deflection element (3). The invention further relates to a method for adjusting the height of the upper retaining point (23) of a three-point seat-belt (2) by means of an inventive height-adjustable deflection device (3), according to which the deflection element (11) is pushed backwards against a pressure, is rotated about the rotational axis (13) and then released again.
